WEATHER BUREAU 30-DAY OUTLOOK
July 1963
The Weather Bureau's 30-day outlook for July calls for temperatures to average
above seasonal normals in most of the eastern two-thirds of the Nation, except
for near to below normal in North Atlantic, South Atlantic and Gulf States. Over
the Far West generally below normal temperatures are anticipated. Rainfall is
expected to be subnormal over the Great Lakes, central Plains and middle
Mississippi Valley. Above normal amounts are predicted for the Southeast and
Northwest, and near normal in areas not specified.
WEATHER OF THE WEEK ENDING JULY 1
A large high pressure area centered over Ohio provided warm sunny weather to most
of the eastern part of the Nation during the first half of the week. Light rain
showers fell over the Carolinas, Georgia and the Florida Peninsula. Hot humid
air flowed northward on the western side of the mound of high pressure. This
air brought more than 2 inches of rain to most of southeastern Nebraska Sunday
night and early Monday morning. Fourteen inches fell at Garrison, Nebraska,
June 23-24, washing out 200 bridges and causing $10 million damage in the vicinity.

HAWAIIAN INSECT NOTES
The following notes on Hawaii insect conditions were presented at the 690th
meeting of the Hawaiian Entomological Society held on June 10, 1963.
An unidentified FLAT BUG (Aradidae) was discovered by Donald Oatley, a general
entomology student, in May 1963. This bug was somewhat abundant, feeding on
fungus under loose bark of trees above Fort Shafter, Oahu. Specimens have
been sent to U. S. National Museum for identification, This is the first
record of this family in Hawaii. (B. D. Perkins).
A general entomology student collected an adult of a predaceous CARABID
(Tefflus zanzibericus alluaudi) in the Kaneohe area, Oahu, recently. This
carabid was introduced in 1952, 1953, 1957 and 1959 to control a giant African
snail (Achatina fulica). This is the third recovery and the first in 2 years
from this area, indicating that this carabid may have become established.
(D. E. Hardy).
Young shoots of a navel orange showing severe damage by feedings of SOUTHERN
GREEN STINK BUG (Nezara viridula var. smaragdula) were exhibited. In general
the feeding of 2 pairs of adults produced complete collapsing of the shoots :
between 24 and 48 hours. There was no recovery... (Goad. Davis).

- Weather of the week ending July 1 (continued from page 740)
The eastward movement of a front that extended from North Dakota to New Mexico
set off moderate to heavy showers in North Dakota, Minnesota and Wisconsin,
Light rains also fell over the Pacific Northwest. Hot sunny weather prevailed
over the Southwest, with afternoon temperatures approaching or exceeding 100°
daily. By midweek,the high pressure area had moved slowly southeastward to a
position off the coast of South Carolina and Florida. A slowly moving cold
front stretched from the middle Plains to New England. Hot humid air moved
across the South Central States to New England, bringing 90° temperatures as
far north as Burlington, Vermont. Thursday afternoon, the temperature shot to
97° at Philadelphia, Pennsylvania, and 95° or higher over the central Plains,
the southern Rockies, and southwestern deserts. Albuquerque, New Mexico,
registered 99°; Goodland, Kansas, and North Platte, Nebraska, 101°, A few
heavy thundershowers occurred along the front which became almost stationary.
Near the weekend, cooler weather moved inland across the Pacific Northwest. The
Northeast also cooled. By daytime, heating sent the mercury to the upper 90's
over the Plains and Prairies. Pierre, South Dakota, registered a sizzling 108°
on Saturday afternoon, and Marquette, Michigan, registered 101° Sunday, equaling
the previous June record-high temperature. As July began, the hot humid weather
continued over most of the eastern half of the Nation, but more pleasant temper-
atures prevailed over the Rockies and Pacific Northwest. No rain, or only light
showers, fell during the week over most of the Nation from the Pacific Ocean to
the High Plains. Some exceptions were the extreme Northwest and a few isolated
spots in the central Plains. Rainfall was also light in the Ohio River Valley
and northward to Canada. Precipitation totals exceeded 4 inches at a few stations
near the Gulf Coast between Corpus Christi and Houston, Texas, at Jacksonville
and Orlando, Florida, and at a few stations in southeastern Georgia. Torrential
rains, with amounts of 5 to 7 inches, hit the Athens, Georgia, area late Wednes-
day, causing flash flooding and extensive damage to roads and buildings. Temper-
atures averaged below normal over central and southern Texas and eastward to the
Carolinas; also from the Pacific eastward to Montana, Wyoming, Utah and Arizona.
They averaged above normal over New Mexico, Colorado, Nebraska, the Dakotas, and
eastward to the Atlantic Ocean. Temperature departures ranged from -9° at Salem,
Oregon, and Red Bluff, California, to +11° at Goodland, Kansas, International
Falls, Minnesota, and Marquette, Michigan. (Summary supplied by U.S. Weather Bureau).

FIELD METHOD FOR SEPARATING THE CEREAL LEAF BEETLE, Oulema melanopa (L.),
FROM SIMILAR-APPEARING SPECIES OF LEMA IN THE UNITED STATES
Prepared by
Darol L. Kaufmann 1/
The cereal leaf beetle, Oulema melanopa (L.), is presently known to occur in
several counties in southwestern Michigan, northern Indiana and northwestern
Ohio. Its economic importance and the danger of its dispersal made apparent the
need of a field method for distinguishing it from similar-appearing species in
the genus Lema known to occur in the United States.
Oulema melanopa (L.):
Sternites of abdomen dark or metallic blue;
legs with some reddish areas,
U. S. Species of Lema superficially resembling
O. melanopa:
L.
longipennis Linnell Sternites and legs dark
or metallic blue.
L. collaris Say Sternites and legs dark
or. metallic blue,
L. brunnicollis Lac. Sternites and legs dark
or metallic blue,
L. texana Cr.* Sternites reddish.
L. cornuta F.* Sternites reddish,
L. simulans Schffr.* Sternites reddish,
Ha S2 yal Were Sternites reddish,
*Leg color not needed to distinguish from
O. melanopa.

WEATHER OF THE WEEK ENDING JULY 8
At the beginning of the week, a cold front extended from a Low centered north of
Lake Superior southwestward to Colorado. A weak warm front extended eastward
across northern New England. South of these fronts, afternoon temperatures were
mostly in the 90's, They reached 95° or higher in a broad band from western
Lower Michigan southwestward to Arizona and nearby portions of California. On
Monday afternoon, the temperature shot to 97° at Philadelphia, Pennsylvania, and
New York and Albany, New York, to 98° at Boston, Massachusetts, and to 101° at
Lancaster, Pennsylvania, and New Brunswick, New Jersey. The weather was espe-—
cially oppressive over the Southeast where the dew points were near or above 70°.
The western end of the front moved northeastward becoming a warm front, and
temperatures near or above 100° continued in the Midwest. Valentine, Nebraska,
registered 101° on July 3. The eastern portion of the front continued southward
and brought cooler, more comfortable temperatures to the North Central and
Northeast. A few stations near the Great Lakes registered record-low tempera-
tures on July 4. Towering cumuli were common over the Rockies. Sunny weather
predominated in the Northwest and the Southwest, with temperatures in the South-
west going past the 100° mark each day. By Friday, both ends of the front had
become stationary. The front then extended diagonally across the country from
Montana to Georgia, A pleasant pattern prevailed in the Northeast -- mild after-
noon temperatures and. record or near-record low temperatures in the early morning.
Numerous localities in New England saw temperatures no higher than the 70's from
July 4 to 7, and minimum temperatures were mostly in the 40's and 50's. On the
hot side of the front, early morning temperatures were mostly in the 70's and
afternoon temperatures were in the 90's or higher. Near the end of the week,
another mass of cool, dry air was pushing across the Canadian Border from Minne-
sota to New England, It kept the humidity low and the temperatures at comfortable

COTTON INSECTS
BOLL WEEVIL (Anthonomus grandis) - SOUTH CAROLINA - Emergence from hibernation
about complete; first-generation adults appearing in cotton fields down state.
One-fourth of counties reporting had average of 30 percent punctured squares, in
untreated fields. Average percent punctured squares for State 18 in untreated
fields and 6 in treated fields. (Cott. Ltr., July 1). GEORGIA - Percent
punctured squares in 20 counties surveyed June 27-July 3 was 1-88 in 10 percent
of fields, 11-25 in 8 percent of fields, and 26-50 in less than one percent of
fields. Infestation increased slightly from previous week; controls good in spite
of rainy weather. (Jordan). ALABAMA - Percent punctured SquareS remained static;
however, live adults reported as far north as Madison County. Emergence of first-
generation adults from south to north has been extremely light, and has been in
direct relationship to square infestation counts in individual fields over past
4 weeks. Isolated infestations as high as 40 percent reported. (McQueen et al.).
TENNESSEE - Infestations light in western area. Square counts could be made in
about 50 percent of fields surveyed. Percent punctured squares ranged 0-12,
averaged 3, in those fields found infested. Emergence slow and infestions much
lower than expected. Weather conditions ideal for buildup. (Locke). ARKANSAS -
Present in 46.2 percent of 5,922 fields scouted, 2 percent fewer fields than same
time in 1962. In spite of increase in activity, only 6 fields had infestation
levels that would justify controls. (Wkly. Cotton Ins. Rpt.; June 28). LOUISIANA -
First-brood adults present in many Tallulah area fields; infestation levels gener-
ally low. (Smith et al.). MISSISSIPPI - Punctured squares found in 8 of 31
fields checked in delta counties; averaged less than 1 percent in infested fields.
- 194 -
Adults, probably first generation, observed in experimental field. (Pfrimmer et
als) OKLAHOMA - Infestations continue light in cotton-producing areas of
State. No counts over 8 percent punctured squares reported. (Okla. Coop. Sur.).
TEXAS - Situation remains generally favorable except in some central and
southern areas where infestations reaching economic levels. (Tex. Coop. Rpt.).
Percent punctured squares averaged 25.4 in untreated fields and 0.6 in treated
fields in McLennan and Falls Counties. (Cowan et al.).
SPIDER MITES - CALIFORNIA - Tetranychus atlanticus abundant throughout most
of Kings County. (McCutcheon, June 24). Serious T. atlanticus damage to cotton
noted in Firebaugh, San Joaquin, Tranquillity and Kerman area of Fresno County;
considerable defoliation occurring. (Ferris, June 27). T. atlanticus continues
to cause severe defoliation in untreated cotton fields in Shafter area, Kern
County; rapid growth of cotton may mask many infestations. T. telarius
increasingly evident throughout Kern County and T. pacificus becoming evident in
many fields in West Side area. (Leigh, June 27). TENNESSEE - Tetranychus
cinnabarinus, T. tumidus, T. lobosus and T. atlanticus positively identified as
most prevalent species of mites that usually infest cotton over western area;
most common species T. atlanticus. Populations and number of infestations
increased over previous week. Further increase expected if controls not applied.
(Locke). MISSOURI - Marginal and spot infestations of unspecified species
present in 155 of 727 cotton fields scouted. (French). ALABAMA - Spider mite
activity retarded by rains and cooler weather; isolated infestations present
throughout State. (McQueen et al.).

nearly all counties. Some plants examined had 4-6 hollowed-out Squares per
plant, with lesser numbers of injured squares on adjacent plants. (Cotte sictx
July 1). GEORGIA - Counts made in 20 counties week of June 27-July 3. Eggs
per 100 terminals 1-10 in 78 percent of fields, 11-25 in 7 percent, 26-50 in
2 percent, and none in 12 percent of fields. Only 1 percent of fields had over
50 per 100 terminals. Larvae per 100 terminals 1-3 in 51 percent of fields, 4-10
in 14 percent, 11-25 in 2 percent and none in 34 percent of fields. Bollworms
appear to be more of a problem in southwest than southeast section of State.
Potential for damage remains high. Damaging populations currently present in
about 15 percent of fields checked. (Jordan). ALABAMA - Greater numbers
appearing in southern portion of State, with extremely heavy infestations noted
in Autauga, Dallas and Elmore Counties. Although eggs appearing in most fields,
rains apparently reduced survival. (McQueen et al.). TENNESSEE - Continue
a problem in some western area fields, but infestations not general. Counts
0-20 larvae or eggs per 100 terminals. Larvae averaged 3 per 100 terminals in
infested fields; some controls started. (Locke). MISSOURI - Only 24 of 727
fields scouted infested with 0-3 larvae per 100 plants. (French). ARKANSAS -
Activity about same as last year at this time; more found than previous week.

south central and east central areas. Larval infestation 8-42 percent in 300
acres of cotton checked in Webber Falls area, Muskogee County. (Okla. Coop.
Sur.). TEXAS - H. zea moth activity increased greatly and heavy egg deposition
occurring in most areas in southeastern half of State. H. virescens populations
about the same, but increasing H. zea population overshadowing damage caused
by H. virescens. (Tex. Coop. Rpt.). In McLennan and Falls Counties, infestation
remains heavy and injurious numbers occurring in most fields. Square injury
averaged 10.5 percent in treated fields and 11.5 in untreated fields. Boll
injury averaged 10.4 percent in treated fields and 10.3 percent in untreated
fields. (Cowan et al.).

Survey Methods
Survey Method for Grape Root Borer (Vitacea polistiformis polistiformis)
as Used in Arkansas
Prepared by
V. G. Attwood, W. D. Wylie and W. P. Boyer
A survey method for grape root borer has proved successful in determining the
extent of adult emergence in Arkansas. The number of larvae in roots cannot, of
course, be determined without destroying the vines. The adult moth is often
mistaken for a common wasp when seen flying about a vineyard.
A brief account of the life cycle in northwest Arkansas gives the basis for the
survey method. The life cycle requires two years. Adults are present in the
field from approximately the middle of July to the middle of August. They are
most active during the hottest part of the day and may be seen on the wing from
about 9 a.m. to 4 p.m. The adult female deposits over 400 eggs, enough for one
egg per vine for an entire acre of grapes. The eggs hatch in two weeks: Only
about 10 percent of the larvae become established, and these spend 22 months in
the roots. The pupal stage lasts four to five weeks. The remaining three to
four weeks are required for the adult and egg stages.
One survey method has proved successful. When pupae come to the surface of the
soil, about one-third of the pupal case extends above the ground. It is in this
position when the adult emerges. After the adult emerges, the empty pupal cases
will remain intact. Ninety percent or more of the adults emerge within a one-foot
radius of the base of the vine. Searching under the vine for the remaining pupal
cases during the last half of July and all of August will reveal the presence of
the root borer,

WEATHER OF THE WEEK ENDING JULY 15
A few thunderstorms occurred along the southern edge of Dixie as a mound of polar
continental air pushed farther toward the Gulf. By Wednesday morning, the eastern
half of the Nation was clear, cool and comfortable. Early morning temperatures
dropped into the 30's in some valleys in the Appalachians in Pennsylvania and
low-temperature records were broken at many stations from Michigan to Massachu-
setts. Afternoon temperatures over the northeastern quarter of the Nation were
mostly in the 70's. Some cloudiness and a few isolated afternoon thundershowers
occurred along the western edge of the Plains. Some communities in Kansas received
from 5 to 10 inches of rain on the 10th and llth. low clouds and light rain or
drizzle persisted along the northern Pacific coast; southwestern deserts continued
hot. As the cool air pushed eastward into the Atlantic, southerly winds brought
warm, humid air from the Gulf to replace it. Temperatures at midweek reached
the 90's over the Plains and the 70's and 80's over the northeastern quarter of
the country. Miles City, Montana, registered 95° on Wednesday. The Southwest
continued hot during the entire week. Afternoon temperatures at Needles,
California, ranged from 101° on Tuesday to 115° on Sunday, July 14. Blythe,
California, registered 96° Thursday night at midnight. Saturday morning, a cold
front extended from western Nebraska to Lake Superior, Prefrontal showers
occurred from Kansas to Wisconsin. As the front advanced, the showers spread
eastward, Areas in Wisconsin, Michigan, Illinois, Indiana and Ohio received
from 1 to 2 inches of rain from this storm, The showers continued their eastward
movement. By Saturday afternoon, most States from Minnesota to Michigan and
southward to the Gulf received rain, By Sunday, rain had fallen over the eastern
half of the Nation except that, in Florida, the showers were widely scattered,
Precipitation was generally light over the western part of the Nation. An excep-
tion was Williston, North Dakota, where 5.93 inches fell. Wide areas in Cali-
fornia, Nevada, Oregon, Idaho, Utah and Arizona received no rain or only light
sprinkles, Heavy rains fell over parts of Mississippi, Arkansas, Oklahoma, .
Kansas, Missouri and Iowa. Ha.l as large as baseballs fell at Hastings, Nebraska.
Rainfall over the central and eastern portions of the country was unevenly distri-
buted. Scattered areas received more than 2 inches and nearby stations received
less than 1) inch.
Temperatures averaged above normal over a narrow strip along the Pacific coast;
also over the eastern slope of the Rocky Mountains and most of the High Plains.
They averaged below normal over the western slope of the Rocky Mountains and
westward almost to the Pacific coast, over most of the central Plains,eastward to
the Atlantic Ocean. Temperature departures ranged from -7° over north central
Oregon, -11° at Huntington, West Virginia, and -12° at Raleigh, North Carolina,
to +6° at Roswell, New Mexico. (Summary supplied by U. S. Weather Bureau).

Quarterly Citrus Insect and Mite Outlook in Florida - July through September
This outlook is based on the assumption that weather beyond the period of the
current U. S. Weather Bureau's 30-day outlook will be normal. Therefore, the
forecasts given below cannot be viewed with the same degree of confidence as
those in the "Insect Situation in Florida" usually given twice each month.
Effects of the December 1962 freeze were so great that the pest populations,
except for citrus rust mite (Phyllocoptruta oleivora), are still quite different
in groves that were defoliated. This is true, but to a lesser extent, for trees
that have now attained a full canopy of healthy leaves.
In Freeze-damaged Groves - CITRUS RUST MITE (Phyllocoptruta oleivora) will remain
generally high through July and August with some scattered, high infestations
in September. TEXAS CITRUS MITE (Eutetranychus banksi) , CITRUS RED MITE
(Panonychus citri) and WHITEFLIES will be below average in most groves. A few
groves will develop heavy infestations in August and September. SCALE INSECTS
will increase from current low levels during July and August, but few infesta-
tions will be important.
- 823 -
In Undamaged Groves - CITRUS RUST MITE will be near normal high level for July
and August, then drop into low range in September. About 40 percent of groves
will have moderate or heavy infestations. TEXAS CITRUS MITE will subside in
July and drop to low level in August. CITRUS RED MITE will be important only
in scattered groves. BLACK SCALE (Saissetia oleae) will continue above average
until mid-August. GLOVER SCALE (Lepidosaphes gloverii) will be above normal
abundance. About 10 percent of groves will have heavy infestations in the
interior of trees. CHAFF SCALE (Parlatoria pergandii) will continue above
normal but no further increase until September. YELLOW SCALE (Aonidiella
citrina) may become unusually numerous on leaves and fruit in a few groves.
WHITEFLIES will be normally abundant through July. MEALYBUGS will soon drop
to low level and remain low. FLORIDA RED SCALE (Chrysomphalus aonidum) will
remain at very low level in all areas. (W. A. Simanton (Citrus Expt. Sta.,
Lake Alfred)).
YELLOW SCALE (Aonidiella citrina) - FLORIDA - Moderate on 2,250 sweet orange

WEATHER OF THE WEEK ENDING JULY 22
Typical summer weather continued as seasonal storms periodically raged from the
Great Plains eastward, and mostly dry, hot days, and cool nights were the order
for the Far West. Average temperatures for the week departed very little from
normal; the largest departures on either side being only 7°. Daily maxima over
90° were generally restricted to the southern half of the Nation as the period
opened, but were being observed in all areas by the 19th. States east of the
Mississippi underwent a cooling trend during the weekend, while 100° heat surged
into the northern Rockies and Plains. The Eversoll Ranch in the southeast corner
of Colorado recorded a 110° high, nearly as warm as the hottest, 114° on the 21st
at Needles, California, where the temperature never went below 82°. A frosty 25°
from Bondurant, Wyoming, was the coolest reported.
Precipitation was almost nil in California and Nevada, and mostly limited to
widely scattered showers over the remainder of the Far West. However, rain on
2 or 3 days along the Pacific Northwest coast left totals to over 2 inches. At
the close of the period the Phoenix, Arizona, Airport had its first measurable
precipitation in nearly 3 months. Rainfall totals were quite variable over the
eastern half of the Nation, ranging from none in sections of Texas, North Carolina,
and Virginia to over 6 inches in Arkansas and a strip from southern Minnesota into
northern Indiana. On the 16th, torrential rains swamped the Chicago, Illinois,
area, and even heavier downpours of 8.35 inches in 12 hours at Hot Springs,
Arkansas, led to local flooding. While hailstorms plagued the communities of
Harris and Estherville, Iowa, on the 18th, an afternoon thundershower dumped 4.15
inches of rain on Reinbeck, Iowa. That same day, heavy damage was sustained in
the areas of Austin and Albert Lea, Minnesota, by a rampaging tornado, while over
4 inches of rain flooded the northern half of Huntsville, Alabama. Severe storms
continued with equally punishing results on the 19th. Moline, Illinois, had
70 m.p.h. wind-whipped rains of 2 inches in only 45 minutes. A gas station was
tornado-damaged in Dayton, Ohio. Three buildings were unroofed and four funnels
sighted near storm wracked Chicago, Illinois. The Coast Guard Station at Waukegan,
Illinois, measured a thunderstorm-triggered seiche of 6.4 feet; the wave moved
westward across Lake Michigan.
Weekend weather reached severe proportions locally in the East Coast, Ohio Valley,
and Great Lakes States. Showery weather in southwestern Connecticut left 2.50
inches at Bridgeport, on the 2lst, while Chicago, Illinois, was again hit with
large hail and heavy rains which caused power outages, uprooted trees, capsized
boats, and flooded roads. Unofficial reports of 5 to 8 inches of rain were
received from Hammond, Indiana, and hailstones to golf-ball-size fell in. Florida
and near Mobile, Alabama, during stormy periods. Hail near Montello, Wisconsin,
stripped leaves from trees in a 2-mile wide path on the 2lst. (Summary supplied
by U.S. Weather Bureau).

CEREAL AND FORAGE INSECTS
GRASSHOPPERS - WISCONSIN - Grasshoppers range 30-60 per square yard in portions of
western Dane, southern Lafayette, southern Grant, southern Green and southern Rock
Counties; numerous in Pepin, Marquette, and portions of Columbia and Waushara
Counties; however, potential is great. Feeding noted in marginal corn rows in
Dane, Portage and Walworth Counties; some feeding on tobacco noted in Richland
County and on soybeans in lighter soiled areas. Extensive feeding on soil bank
fields in western Dane County caused 50 percent defoliation in one field and 80
percent in another field. Ranged third instar to adult in these fields;
Melanoplus bivittatus dominant. Delayed grasshopper hatch evident in southwest
area; second stage nymphs evident in some fields; populations in Ozaukee,
Sheboygan, Manitowoc, Kewaunee, and Door Counties insignificant. Populations
light in Shawano, Outagamie, and Winnebago Counties. Treatment reported only in
Pepin County. (Wis. Ins. Sur.). MINNESOTA - Counts in southeast generally low;
average Six per yard, with 15 to over 20 per square yard in occasional field. In
northwest, most ‘hoppers in field margins, ditchbanks and recently cut alfalfa;
M. femurrubrum 75 percent first instar, 25 percent second instar. Generally low
in central district. In Benton and Sherburne Counties, ranged 15-25 per square
yard in some field margins; movement into cropland observed in few fields. Fields
should be checked; early treatment recommended. (Minn. Ins. Rpt.). NORTH DAKOTA -
Survey in Cass, Barnes, Steele, Griggs, Foster, and Stutsman Counties showed
average of four ‘hoppers per square yard in margins and one in the field; averaged
ten per square yard in field and 15 in margins of few scattered alfalfa fields in
Barnes and Griggs Counties. Dominant species M. femurrubrum, M. bivittatus, and
M. sanguinipes; most in second through fourth instar. Few M. sanguinipes and
M. bivittatus adults noted. Habitats included alfalfa, small grains and soil bank
‘Iands. (Wilson). Rangeland survey in northern Billings County showed range of
less than one to 20 per square yard (average six); M. sanguinipes, Ageneotettix

required in central and northern counties. (Ins.-Dis. Newsltr., July 23).
ORCHARD MITES - MISSOURI - Mixed populations of Tetranychus telarius and.
Panonychus ulmi present in all areas of State but vary greatly. Spider mites
will probably continue as major problem in both apple and peach orchards until
fall rains. S@WkKLy. (Rpt. EreGrse),, culiy.24),
BLUEBERRY MAGGOT (Rhagoletis pomonella) - NEW JERSEY - Maggots now very
noticeable in untreated blueberry areas; some shipments of fruit rejected because
of too excessive infestation due to poor control program. Adults still very
abundant. (Ins.-Dis. Newsltr., July 23).
TRUCK CROP INSECTS
MEXICAN BEAN BEETLE (Epilachna varivestis) - NEW YORK - Very scarce this year;
not expected to be problem for bean growers. (N. Y. Wkly. Rpt., July 22).
UTAH - Damaging several home gardens at Tooele. (Knowlton).
POTATO LEAFHOPPER (Empoasca fabae) ~ NEW YORK - Building up on beans; controis
needed. (N. Y. Wkly. Rpt., July 22).
—y {Xe} 1
GREEN PEACH APHID (Myzus persicae) - UTAH - Moderately numerous on sugar beets
and potatoes at southwestern Granger, Salt Lake County. (Knowlton).
COTTON INSECTS
BOLL WEEVIL (Anthonomus grandis) - SOUTH CAROLINA - Infestations vary greatly;
punctured squares above 25 percent in untreated fields in one-third of counties
reporting. Dorchester, Berkeley, Jasper and Lee Counties report 45-64 percent
of squares punctured. Another one-third of counties report less than 15 percent
of squares punctured. Normal buildup occurring. Migration expected to begin
this week in southeast and about August 1 in Piedmont. (Cott. Ltr., July 22).
First-generation weevils increasing more rapidly in Florence area, but infesta-
tions still relatively light. (Taft et al., July 24). GEORGIA - Percent
punctured squares 1-10 in 56 percent of fields,11-25 in 29 percent, 26-50 in 9
percent, over 50 in 3 percent during period July 18-24. (Jordan). ARKANSAS -
Weevil activity increasing in southwest, but below normal statewide. Increased
activity expected next two weeks. (Wkly. Cott. Ins. Rpt., July 19). LOUISIANA -
Infestations generally light in Tallulah area, but some damage occurring where
showers interfering with control schedules. (Smith et al.). MISSISSIPPI -
Percent punctured squares ranged 0.25-77 (averaged 15.5) in 15 of 27 fields
checked in delta area. Population increasing in infested fields. (Pfrimmer
et al.). TEXAS - Nearing economic levels in some older cotton in northwest.
(Tex. Coop. Rpt., July 19).
BOLLWORMS (Heliothis spp., et al.). - SOUTH CAROLINA - Larvae per 100 terminals
July 18-24 were 1-3 in 45 percent of fields, 4-10 in 25 percent of fields,
11-25 in 5 percent of fields and over 25 in only 1 percent of fields. (Jordan).
ARKANSAS - Third-generation moth emergence heavy in some areas, especially
in sections of southeast and southwest. Egg counts increased rapidly. (Wkly.
Cott. Ins. Rpt., July 19). LOUISIANA - Of primary importance in Tallulah
area at present. Egg and larval terminal counts much higher than in previous
week. Some boll damage occurring. (Smith et al.). MISSISSIPPI - Percent
injured squares ranged 0.2-3.25 (averaged 1.44) in 20 of 27 fields checked in
delta area. Moderate moth flight still underway. Egg deposition appears to be
primarily down in plant. First and second-stage larvae found in white blooms
in several fields. (Pfrimmer et al.). TEXAS - Continues most damaging cotton
insect over State. (Tex. Coop. Rpt., July 19).
PINK BOLLWORM (Pectinophora gossypiella) - TEXAS - Much of cotton in infested
areas of Matagorda County nearing maturity, but considerable damage still being
inflicted. In Cayonose area of Pecos County, infestation still persists and
controls being continued. (Tex. Coop. Rpt., July 19).
GARDEN WEBWORM (Loxostege similalis) - TEXAS - Generally distributed over
northwest and south plains areas; some heavy infestations required controls in
these sections. (Tex. Coop. Rpt., July 19).

BEET ARMYWORM (Spodoptera exigua) - GEORGIA - Infestations found in 10 percent
of cotton fields checked in Decatur, Terrell, Sumter, Calhoun, Early, Clay,
Miller, Stewart, Colquitt and Grady Counties July 18-24. Light in all but very
few fields. Infestations appear to be decreasing. Another generation possible.
(Jordan). TEXAS - General, light infestations present over wide areas of
northwest constitute potential threat if conditions remain favorable for
population increases. (Tex. Coop. Rpt., July 19).
OOo
LYGUS BUGS (Lygus spp.) - CALIFORNIA - Counts reaching economic levels in many
fields throughout San Joanquin Valley. Reinfestation occurring in some fields
already treated. Fields should be checked closely and controls applied where
economic levels found. (Burton et al., July 22).
COTTON FLEAHOPPER (Psallus seriatus) - TEXAS - Economic populations present in
many areas of northwest and south plains sections where much cotton is in
critical fruiting stages. Controls being applied in many instances. (Tex.
Coop. Rpt., July 19).
SPIDER MITES - CALIFORNIA - Tetranychus telarius becoming severe in Kerman area
of Fresno County; ranged 50-100 per leaf in alkali soil areas. Generally
light in Clovis area with occasional fields requiring treatment. Increasing in
Mendota, Firebaugh, Tranquillity and San Joaquin areas with some fields being
treated. (Ferris, July 19). Increasing in western part of county where controls
not applied. T. pacificus appears dominant. (Leigh, July 19). Mites appear to
be less numerous in Kern County, but cotton has grown rapidly and masked some
injury. T. atlanticus continues abundant on lower portion of plants. (Black,

INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES
A FRUIT-TREE SPIDER MITE (Tetranychus viennensis Zacher)
Economic Importance: This tetranychid mite has become of conisderable importance
on fruit trees in various areas of Europe since it was first described by
Friedrich Zacher in 1920. It has been known to occur in parts of Western Europe
for many years, but was only recently found to be present in Greece, Turkey and
Japan. It was considered serious on plum, apricot and peach during 1959 in
Turkey, and damage was severe on apple locally in Greece in 1960. Apparently,
this species has become of greater importance in Europe as a result of the wide-
spread application of modern insecticides in orchards for the control of other
pests.
T. viennensis has been intercepted on several occasions at U.S. Ports of entry.
From 1958 through 1963, the pest was taken 3 times in Hawaii; twice at Seattle,
Washington; and once each at Wilmington, North Carolina; Miami, Florida; and
New York, New York,
Hosts: Recorded on a number of hosts, including apple, pear, sweet and sour
cherries, European birdcherry, quince, plum, peach, apricot, hawthorn, black-
thorn and oak,
Distribution: Europe (recorded in Austria, Bulgaria, England, France, Germany,
Greece, Hungary, Sweden and Switzerland). Also recorded in Turkey, U.S.S.R.,
China, Korea and Japan.
Life History and Habits: The biology as studied in the Mediterranean region of
France on apples in 1953 is as follows: Females overwintered in groups, mainly
in cracks in the bark or in the soil around the trees. They became active in
the spring and dispersed to the young leaves. At Montpellier, they became
active about March 25 and were found on all parts of the trees by April 7. They
fed and oviposited on the lower surface of the outer leaves of the terminal buds.
Natural mortality was high in the spring and increased still more in May and
June owing to the activities of predators. However, large populations developed
in the summer under the influences of high temperatures, long daylight hours,
an abundance of mature leaves and the destruction of natural enemies by organic
insecticides and acaricides, Maximum numbers were present in August and
September, and the hibernating females were produced in early autumn and entered
diapause in late September or early October when the critical photoperiod was
13 to 14 hours per day. The last males and eggs were seen in October. At
Sapporo, Hokkaido, Japan, the mite was found to overwinter in the adult stage.
Overwintered mites spend the winter much as they do in France and appear the
next year on leaves of host trees from the end of May to the beginning of June.
There are four or five generations a year in Hokkaido and an extra one at
Kuroishi, Honshu, Japan.
Tetranychidae, Acarina No. 155 of Series
CEIR 13 (31) :8-2-63
ROO Sila
Description: FEMALE - This is a typical tetranychid mite, with the following
exceptions. It is unique in having the distal ends of the peritreme anastomosing.
Also, the dorsal striations are transverse on the posterior portion of the body
as in Tetranychus pacificus. MALE - Aedeagus is bent sharply dorsad, and the
distal knob is modified aS a small anterior angulation near the base of the bent
portion, with the caudal angulation very attenuated and tapering. (Prepared in
Survey and Detection Operations in cooperation with other ARS agencies.)

up in northwest area week ending August 2; one-half to three-fourths grown in
Hardin and Hancock Counties. (Lyon). ILLINOIS - Melanoplus spp. abundant in
clover and alfalfa in northern area; up to 50-60 per square yard found in some
fields. Populations in grassy roadsides generally under 10 per square yard, with
occasional spot as high as 40 per square yard. (Ill. Ins. Rpt.). MISSOURI -
Damage by Melanoplus spp. evident in pastures and legumes in dry spots in north-
west areas. Counts in these areas ranged 5-31 per square yard in field. Marginal
feeding also evident on row crops in these areas. (Munson, Thomas, Wood; July 27).
IOWA - Grasshoppers eating silks from corn in first 5-6 rows and ragging soybeans
adjacent to fencerows and roadsides; M. differentialis, third instar to adult,
dominant. Populations range 15-30 per square yard in roadsides. (Iowa Ins. Inf.,
July 29). WISCONSIN - Nymphs of M. differentialis maturing in more advanced
areas of State. Populations, approximately 50 percent M. differentialis and 50
percent M. femurrubrum, completely defoliated soil bank alfalfafield in western
Dane County. Corn also being damaged in area. Populations little changed in
Rock, Green, Dane, Columbia, Marquette, Waushara, Portage, Waupaca, Green Lake,
Fond du Lac, Grant or Trempealeau Counties, and damage generally negligible.
Some damage evident in Pepin County where populations of late stage M. femurrubrum
and M. differentialis nymphs range up to 40 per square yard in some alfalfa fields.
Populations, principally M. femurrubrum, light to moderate in Juneau, Eau Claire,
Chippewa and Dunn Counties, with less than 15 per square yard in most alfalfa.
Some damage noted in parts of La Crosse and Trempealeau Counties. (Wis. Ins. Sur.,
July 26). Little change noted in populations to August 2. Adults of both M.
femurrubrum and M. differentialis appearing more commonly in southern areas. |
M. differentialis 30 percent of grasshopper population in Iowa County alfalfa,
25 percent in Lafayette, 40 percent in Grant and 50 percent in Green. M.
femurrubrum nearly entire population in Rock, Walworth, Crawford and portions of
Dane County. Noticeable feeding evident on sorghum in Rock County in which
populations of M. differentialis, about 40 per yard, made up greater share. (Wis.
Tins yy sui) TN
MINNESOTA - Grasshopper populations in southeast, south central, southwest and
central districts higher than anticipated. Warm, dry weather permitted excellent
egg hatch and survival. Economic populations, over 10 per square yard, found
where only light infestations expected. Infestations quite scattered and localized.
M. femurrubrum and M. differentialis ranged 5-54 per square yard in alfalfa and
grassland in Sherburne, Isanti, Mille Lacs and Anoka Counties. Adults appearing
and movement into corn occurring. Severe margin damage to corn seen in high
count fields, especially where M. differentialis dominant. In northwest district,
Kittson and Marshall Counties have few fields with economic numbers; infestations
primarily along roadsides and ditch banks. Very little movement into crops
occurred. In west central district in Douglas County, roadside infestation of
M. bivittatus noted south of Alexandria and moving into adjacent corn fields. In
‘Southwest district, populations average 13 per square yard. Few fields in
Cottonwood, Murray, Lyon and Rock Counties had economic populations. Most
infestations along roadsides in southeast and south central districts. Few fields
in Rice and Olmsted Counties had 20-60 per square yard. (Minn. Ins. Rpt.). NORTH
DAKOTA - Survey conducted in McLean, Sheridan and Burleigh Counties (July 19-26)
showed marginal counts of less than 1 to 25 per square yard. Field counts ranged
from less than 1 to 9 per square yard. Higher counts in flax, late oats and
alfalfa. Some light to severe boll clipping observed in flax. Light leaf strip-
ping seen on late small grain fields. Dominant species M. bivittatus and M,
packardii (approximately 40 percent adults). (Brandvik). Cropland survey (July
19-26) in McKenzie, Mountrail, Williams and Divide Counties showed 3-15 per
Square yard in roadsides and 1-5 in fields. Dominant species M. bivittatus and
M. sanguinipes. (Olson). Survey in Pierce, McHenry, Ward and Bottineau Counties
(July 19-26) gave average counts 5 per square yard in fields and 7 per square
yard in margins. Species involved were M. bivittatus, M. sanguinipes, M.
packardii, M. femurrubrum and Camnula pellucida. Most in fifth instar. Adults
- 902 -
ranged from 0 for M. femurrubrum to 35 percent for M. bivittatus. Twenty-five
percent of M. sanguinipes and C. pellucida adults. (N. D. Ins. Sur.). Adult
survey conducted on rangeland in McKenzie and Dunn Counties July 27-August 2.
Lightly infested rangeland in McKenzie County averaged 4-5 per square yard. Areas
with threatening infestations averaged 8 per square yard. Lightly infested areas
comprised 237,000 acres, and threatening areas covered 10,880 acres. Infestations
in Dunn County (Ft. Berthold) noneconomic. Average less than one. Ageneotettix
deorum, Aulocara elliotti, M. sanguinipes and C. pellucida dominant species.
(Brandvik). SOUTH DAKOTA - Range survey completed in Custer and Fall River
Counties. Custer County has approximately 65,000 acres of infestation (threaten-
ing or higher); approximately 75 percent private or State owned land, and 25
percent U.S. Forest Service land. Light infestation present on 35,000 acres in
Custer County and 20,000 acres in Fall River County. Latter area about 50 percent
private and State owned and 50 percent Forest Service land. M. occidentalis,
Aulocara elliotti, Trachyrhachys kiowa and Ageneotettix deorum species involved.
(Burge, Zimmerman; July 24). Situation unchanged from previous surveys except
for an area in Shannon County which has 20,000 to 30,000 acres of threatening
infested rangeland. Threatening area surrounded by large area of light infestation.
(Burge, Zimmerman; August 1).
NEBRASKA - Grasshopper populations up to 24 per square yard in Dawes and Sioux
Counties week ending July 26. Ageneotettix deorum, Amphitornus coloradus, M.
sanguinipes, T. kiowa and Cordillacris occipitalis species present. (Hagen).
Formal Survey indicates infestations range from noneconomic to a conservative 150
per square yard in crops and conservation reserve land or idle land. New light
infestation appeared in south central area. Extremely high populations present
in Frontier, Dawson and Lincoln Counties. Light to moderate infestations occurring
in Platte River Valley in Garden and Morrill Counties. North central and north-
east areas have light to moderate infestations, chiefly in legumes, conservation

and western New Mexico. Flagstaff, Arizona, received one of the larger totals
with 2.11 inches. Grants, New Mexico, had rainfall amounting to 1.51 inches by
noon on the 3d. From the Great Plains eastward, precipitation was quite general,
but totals were variable. The stations at Wichita, Kansas, and Springfield,
Illinois, measured no rainfall, as did most of Texas. However, a thundershower
dropped 2 inches in 45 minutes on Athens, Georgia. Local totals to 8 inches
were reported from North Carolina and western North Dakota. On the opening day,
local flooding was one result of heavy rain showers amounting to 3.38 inches at
Buffalo, New York.
Severe storms were quite frequent during the period and hail caused crop damage
in Idaho, most of the Plains States, Great Lakes States, North Carolina, and
other scattered areas, Stones to golf-ball size hit Waco, Nebraska, during a
bad storm on the 30th. On the 3lst, a tornado just north of Cadillac, Michigan,
damaged roofs and trees. Twisters also struck near Chicago, Illinois, on the 2d.
A violent nighttime storm on the 3d at Glassport, Pennsylvania, with 90 m.p.h.
winds, was responsible for 2 deaths, injuries to 70 others, and extensive property
damage. Golf-ball size hail and 85 m.p.h, winds had hit Cleveland, Ohio, that

COOPERATIVE ECONOMIC INSECT REPORT
HIGHLIGHTS
GRASSHOPPER damage becoming more noticeable in areas of Illinois, Wisconsin and
Minnesota. Adult surveys underway or completed in North Dakota, South Dakota,
Kansas and Oklahoma. Migration reported in Nevada, and damage continues in Utah.
(pp. 941-942). A second generation of CEREAL LEAF BEETLE developed in Indiana;
some activity continues in Michigan. (p. 942). NORTHERN CORN ROOTWORM adults
abundant on silks of corn in central, west central and northern Ohio, and feeding
continues in Michigan, Missouri and Wisconsin. (p. 942). Egg masses of second-
generation EUROPEAN CORN BORER reported from New York to South Dakota; infesta-
tions heavier than most years in Lee County, Arkansas. (p. 944). CORN LEAF APHID
increasing rapidly on corn at Wooster, Ohio, and in Wisconsin; colonies also
forming on small grains in latter State. (p. 945). SORGHUM MIDGE adults found in
Lea County, New Mexico. (p. 945).
SPOTTED ALFALFA APHID increasing on alfalfa in southeast South Dakota, and
variable in southwest Kansas; found in Larimer County, Colorado, for first time
this season. (p. 945). ALFALFA WEEVIL larvae still causing damage to second-
cutting of alfalfa in Washakie and Big Horn Counties, Wyoming. (p. 946). BEET
ARMYWORM unusually abundant and injurious to several late soybean fields in
Charleston County, South Carolina, during late July. (p. 947).
ORCHARD MITES, principally EUROPEAN RED MITE and TWO-SPOTTED SPIDER MITE, continue
to warrant controls in orchards in several areas of the country. (p. 948). PEACH
TREE BORER caused severe injury to sour cherries in New York; first record of
such injury to this host in the State. (p. 949). First infestation of WESTERN
GRAPE LEAF SKELETONIZER found in commercial vineyard for several years in
Maricopa County, Arizona. (p. 949). BLUEBERRY MAGGOT continues a severe problem
on blueberries in Grand Junction area of Michigan. (p. 950). Several citrus pests
above average levels in Florida, including CITRUS RUST MITE, TEXAS CITRUS MITE,
and several SCALE INSECTS. (p. 950).
BOLL WEEVIL continues to increase on cotton rather generally, with some migration
occurring. Third-generation weevils appearing in Tennessee and numerous in some
delta area fields of Mississippi. (pp. 954-955). BOLLWORMS continue to damage
cotton in Southeast and Mississippi Valley areas, and increasing populations
noted in the West. (pp. 955-956). LYGUS BUGS remain major pests of cotton in
Arizona and California, although SPIDER MITES also important in California cotton.
Spider mites increasing on cotton in several other areas of the country. (p. 957).
The 1963 GYPSY MOTH defoliation survey in Connecticut shows 32,005 acres ‘less
than 50 percent defoliated and 8,135 acres over 50 percent defoliated, (p. 959).

WEATHER OF THE WEEK ENDING AUGUST 12
Though most areas of the Nation had measurable precipitation during the week,
little or none fell in much of the eastern sections of Montana and Washington,
areas of the largest above normal temperature departures. Mostly only very light
or trace amounts moistened the Pacific States; however, moderate rains dampened
local areas of Nevada and southern California. The first sizable showers in
several months fell over the irrigated areas of southern Arizona; 0.62 inch at
Gila Bend was greater than for the calendar year through the end of the previous
week. Elsewhere shower activity was variable, ranging from locally flooding rains
in New York, Iowa, and Colorado to very light amounts in the middle Atlantic
coast, South Dakota, and western Texas. A deluge at Buffalo, New York, heaviest
24-hour fall in 70 years, caused considerable damage due to flooding on the 7th.
By the morning of the 6th, much of Iowa had received rainfall over 2 inches, with
5.25 inches reported locally. Thundershowers in central and southern Texas
brought relief after 4 hot, dry weeks. Heavy rains over the weekend across
central Minnesota into North Dakota left totals to over 4 inches.
Average temperatures were mostly above normal for the first time in 8 weeks in the
Pacific Northwest, due largely to such maxima as the 104° on the 8th at The Dalles,
Oregon. Miles City, Montana, heated to over 100° on 4 days and Glasgow, Montana,
had the largest above normal departure with 9°, The northeast quarter of the
Nation, which had very few stations recording maxima over 90° during the first 5
days, underwent even further cooling from a Canadian air mass over the weekend,
Clouds and rain helped hold Asheville, North Carolina, from warming above 66° on
the 10th. The largest temperature deficiency was 8° below normal at Huntington,
West Virginia. Summer storms took their toll in many areas. On the 8th, trailers
were overturned, utility poles downed, and hail to 1/4 inch in diameter fell
during a thunderstorm at West Fargo, North Dakota. On the same day hailstones to
baseball size fell at Hickson, North Dakota, damaging cars. Dubuque, Iowa, had
an intense rainfall of 3/4 inch in 10 minutes and Morehead, Kentucky, had a down-

CEREAL AND FORAGE INSECTS
GRASSHOPPERS - MICHIGAN - Light infestations of several species reported in
Oegmaw and Ottawa Counties. (Ferris, Van Klompenberg). ILLINOIS - Damage to
some hay fields, particularly red clover, noticeable in northern area. Melanoplus
femurrubrum and M. differentialis present; some M. femurrubrum becoming adults
and flying. Some migration to Soybeans and corn noted. (i111. Ins. Rpt.). IOWA -
Migrating into forage, soybeans and corn fields; controls recommended. (Iowa Ins.
Inf., Aug. 5). WISCONSIN - Becoming more noticeable as more growth occurs and
more feeding done. About 80 percent of M. femurrubrum population matured in
southern area. Considerable feeding on corn adjacent to recently cut alfalfa
occurring and feeding damage apparent in many soybean fields. Populations in
southern and western Dane County, portions of Rock and Green Counties, average
better than 40 per square yard with ratios of better than 35 percent M.
differentialis. This species more prevalent in many corn fields. Dissosteira
carolina adults noticeable, but not significantly abundant, although species
found more commonly feeding on tobacco than other two species. Alfalfafield in
Juneau County stripped by grasshoppers and numbers plentiful in sandier areas.
Populations heavy in northeastern Sauk County, soutnern Grant County and causing
some damage in Ashland, Bayfield and Washburn Counties... Numbers high and
particularly bothersome in gardens in Pepin County. Many homeowners in portions
of Dane County complaining about grasshoppers in lawns. (Wis Ins. Sur.).
MINNESOTA - Development of M. differentialis and M. femurrubrum rapid in west
central district. Majority of infestations along roadsides and field margins.
Counts ranged 9-20 or more per Square yard. Highest counts: found in Chippewa,
Swift and Lac qui Parle Counties. Migrating into soybeans and corn. Some
controls applied in Lac qui Parle and Chippewa Counties. Few corn fields
north of Dawson in Lac Qui Parle County have high numbers of M. differentialis
damaging margin rows; defoliation extended well into these fields. In southwest
district, roadside infestation most common. Few high count fields found in
Pipestone County, ranging up to 40 per square yard. In northwest district, few
soil bank fields in western Marshall and Kittson Counties had margin counts of
10 per square yard and field counts of 7 per square yard. M. bivittatus dominant
in these fields. In south central and southeast districts, few alfalfa fields
in Fillmore, Freeborn and Rice Counties had counts of 20-50 per square yard.
Roadside infestations up to 40 per square yard found in area. (Minn. Ins. Rpt.).
NORTH DAKOTA - Adult grasshopper survey conducted in La Moure, McIntosh and Dickey
Counties. Habitats included small grains, alfalfa, corn and soil bank land.
Infestations ranged 1-12 per square yard and averaged 3 per Square yard. Slight
boll clipping observed on flax. M. femurrubrum development ranged from third
instar to adult and M. bivittatus, M. Sanguinipes, M. dawsoni and M. packardii
ranged fourth instar to adult. (Wilson). Adult rangeland survey completed in
McKenzie, Dunn and Williams Counties. Infestations averaged 4 and 5 per Square
yard. Scattered.areas in McKenzie and Dunn Counties averaged 7 per Square yard.
Totals for these counties included 481,960 acres with light infestations, and
10,888 acres with threatening infestations. An adult survey on cropland in
McLean County showed range of 1-10 per square yard in field (average 3) and range
of 4-16 (average 7) in margins. Dominant species M. bivittatus, M. packardii and
M. sanguinipes., Light boll clipping in flax and light leaf stripping in late
small grains evident throughout area, (Brandvik). SOUTH DAKOTA - Adult survey
on cropland underway, with few of county surveys being completed. Infestations
in these counties varied noneconomic to light to threatening, with heavier
infestations being confined mainly to soil bank fields, alfalfa and field margins,
and roadsides. Dominant species M. bivittatus, M. differentialis, M. femurrubrun,
and M. sanguinipes. (Burge, Zimmerman, Hintz). KANSAS - Adult survey completed
in western two-thirds of State. All stops rated noneconomic except one stop
in Sumner and Barber Counties rated moderate and one stop in Seward and two stops
in Phillips County rated light. (Bell). OKLAHOMA - Adult surveys completed in
23 counties, with 9 counties showing populations of 10 or more per Square yard.
Highest counts noted in Oklahoma County, central area, with 10-40 per square yard
in field margins. Rangeland areas Showed counts of 1-15 per square yard in 5
central and southwestern counties, a light infestation. Several species of
— 942 -
grasshoppers involved. (Okla. Coop. Sur.). WYOMING - Counts of several species
averaged 10-12 per square yard on alfalfa and small grains in Washakie and
Big Horn Counties. (Marks). UTAH - Grasshoppers causing economic damage in some
areas of Carbon County. (Knowlton, Horne). Outbreak quite general over Juab
Valley, Nephi to 6 miles south of Levan, Juab County. Spotted and generally
moderate in alfalfa examined in Uintahand Duchesne Counties; 40 percent winged.
(Knowlton). Control in Fish Lake National Forest east of Beaver at an elevation
of 10,500 feet was very effective over 4,000 acres baited. Population extremely
high, estimated in excess of 100 per square yard. Species were Melanoplus bruneri
and M. borealis. Grasshoppers in area exhibit the alternating generation type
of development. In 1961, a severe infestation developed in this area during late
season. Very little hatching occurred in 1962; but as expected, outbreak very
severe and has occurred this season. (Thornley, Knowlton). Grasshoppers
moving from range and vacant lots to attack crops and gardens along Wasatch
Front, from Clearfield to south Bountiful. (Knowlton, Stokes). Damaging,
especially at Helper. Spring Glenn and Castle Gate, in Carbon County. (Knowlton,
Horne). About 3,000 acres of small grains and pinto beans treated for grasshoppers
in area east of Monticello, San Juan County. (Knowlton, Argyle). Grasshoppers
infesting home grounds south of Moab, Grand County. (Knowlton). NEVADA -
Heavy populations of various species migrating from drying range areas in Washoe,
Pershing and Humboldt Counties. Some migration, causing damage to home yards and
isolated crop lands. Moderate infestation of Idiostatus sp. on 100 acres of
rangeland in Red Rock district of Washoe County. (Coop. Rpt.).

Wireworm Populations During 1962-63 Fall-to-Spring Season and Their Damage to
Potatoes in Vicinity of Charleston, South Carolina, During Spring of 1963:
SOUTHERN POTATO WIREWORM (Conoderus falli) was the only wireworm species in
soil in cultivated fields of potatoes in vicinity of Charleston during fall-to-
spring season of 1962-1963. Populations varied 0-8.5 and averaged 1.9 larvae
per square foot in top 6 inches of soil in 19 untreated fields on 9 farms in
Charleston County during October, November and December. At least 16 samples
6 x 6 inches from each field were screened for wireworms. Population of 3 or
more larvae per Square foot found in only 2 fields. The 1962-63 overwintering
population only about 40 percent of the average prevailing during preceding 10
winter (late fall to early spring) seasons. Populations were not so high as
usual prior to unusually severe freezes in early December, 1962, and there was
a decline of about 67 percent during midwinter in one field under observation,
Average of 13.4 percent of tubers grown in untreated plots in wireworm-control
experiments in 2 plantings showed injury (feeding of any degree) and 3.8
percent showed "damage" as defined by U.S. Market Standards for potatoes,
Proportions of injured tubers from these plots varied 9.1 to 17.7 percent and
damaged tubers varied 2.9 to 4.7 percent. Injury and damage to potatoes in
spring of 1963 lower than average of 10 preceding springs, but number of
untreated plots harvested in 1963 not large enough for adequate comparisons.
Approximately 607 coastal shipping-point inspections of commercial crop during
June showed 1.1 percent of lots with damage in excess of 6 percent (current
tolerance allowance for damage due to all defects for U.S. Number 1 potatoes).
Damage of 3-6 percent found in 12.4 percent of lots inspected and damage of 1.5
to 2.9 in 38.7 percent of lots. Most, if not all of lots inspected, were culled
at packing sheds before inspection which indicated proportion of tubers damaged
in spring of 1963 approximately twice that of 1962 even though a lower wireworm
population apparently present in 1963. Drought during May and first half of
June possibly resulted in more feeding on tubers. (A. Day, R. G. Prochaska,
W.) Jie Reid, Ix.)

HAWAIIAN INSECT NOTES
The following notes on Hawaii insect conditions were presented at the 69lst
meeting of the Hawaiian Entomological Society held on July 8, 1963.
SOUTHERN GREEN STINK BUG (Nezara viridula var. smaragdula) was reported from
Kawaihae, Hawaii, on June 13, confirmed June 14. A single adult was found on the
Hilo Bay Front Area June 29 on rattlebox (Crotolaria sp.); 3 moderately heavy
nymphal infestations on popolo (Solanum nigrum) were found on Kailua-Keahou Kona
Coastal Road July 2. This is the first record of this pest on the Island of
Hawaii. (C. J. Davis).
AN ENCYRTID (Pseudencyrtus sp.) - Specimens were exhibited which had issued from.
puparia of a tachinid fly at Waipahu, Oahu, in June. Pseudencytrus sp. was first
reported from Hawaii in 1961 when found as a parasite of puparia of a sarcophagid
fly (Parasarcophaga misera). The present record of this wasp as a parasite of a
beneficial tachinid fly indicates that it could possibly contribute to the less-
ening of the effectiveness of beneficial tachinids in the State. (J. W. Beardsley).
A BOMBYLIID FLY (Anthrax distigma) - An empty pupal exuvium of what is believed
to be this species was found protruding from a hole in a small mud nest ina
keyhole in an unused door at Mapulehu, Molokai, June 26. When nest was opened,
it was found to contain remains of an adult vespid wasp (Pachodynerus nasidens).
As this solitary vespid species frequently nests in abandoned nests of wasps and
other small cavities, it appears likely that the Anthrax distigma larva developed
as a predator on a Pachodynerus nasidens larva and/or provisions of the nest.
Adults of A. distigma are often noted investigating small crevices in rocks, walls,
and other places. (J. W. Beardsley).
GRAY SUGARCANE MEALYBUG (Pseudococcus boninsis) - A culture containing normal,
gray colored individuals and an unusual white form of this species was exhibited.
The white form was discovered in a cane field on Waipio Peninsula, Oahu, during
March, and at first was thought to be a distinct species; however, microscopic
examination showed it to be identical with the gray form and breeding experiments
showed that both forms interbred readily. The white condition is manifest in
adult males as well as females and immature stages. (J. W. Beardsley).
A FLAT BUG (Mezira membranacea) - The undetermined species reported in CEIR 13
(27) :773 has been determined as M. membranacea (Fabricius) by R. L. Usinger.
This is a common species throughout Southeast Asia, extending from India to
New Guinea, and north to Taiwan. The species could become very abundant in forests.
This is the first record of the family Flatidae in Hawaii. (D. E. Hardy).

COOPERATIVE ECONOMIC INSECT REPORT
HIGHLIGHTS
Adult GRASSHOPPER surveys completed in Washington, Arizona and New Mexico; surveys
in latter State indicate lowest populations in many years. Grasshopper buildup
noted on cropland in southwest North Dakota, and damage to various crops continues
to occur in areas of Minnesota, Wisconsin, Illinois and Missouri. (pp. 977, 978).
SORGHUM MIDGE found on sorghum along Texas line in Lea, Curry and Roosevelt
Counties, New Mexico. Damage evident and many growers treating. Increased CORN
EARWORM infestations expected in soybeans in Virginia. (p. 978). NORTHERN CORN
ROOTWORM adults causing greater economic damage than previous years in Ohio and
lodging of corn severe in isolated spots of McCook County, South Dakota. (p. 979).
SPOTTED ALFALFA APHID found for first time since 1956 in Wisconsin, and northern
most movement in South Dakota advanced to middle Spink County. Moderate to heavy
infestations of the aphid observed in southwest Missouri; and populations heavy
on alfalfa in areas of Prowers, Bent, Otero, Crowley and Pueblo Counties, Colorado.
Spotted alfalfa aphid moderate to heavy on several fields of alfalfa in Chaves,
Eddy and De Baca Counties, New Mexico. (p. 981). JAPANESE BEETLE heavy and
causing severe damage to soybeans and defoliation of plums at Wooster, Ohio.
(pp. 983, 985). SOUTHERN CORN ROOTWORM moderate on peanuts in Early County,
Georgia. (p. 1000).
In Arizona, additional MEXICAN FRUIT FLY specimens collected and specimens of
CITRUS WHITEFLY collected on out-of-State shipment of dwarf citrus trees. (p. 983).
In Michigan, TWO-SPOTTED SPIDER MITE continues high on orchards in southwestern
area, and young larvae of ORIENTAL FRUIT MOTH noted on new growth of peach
nursery stock in Van Buren County and on ripening peaches in Allegan County.
(pp. 984, 985). PEPPER MAGGOT infesting commercial peppers in Warren, Vance,
Franklin and Wake Counties, North Carolina; lots from some fields rejected for
canning. (p. 985).
BOLL WEEVIL and BOLLWORMS continue to damage cotton in number of Southeastern
and Mississippi Valley areas; controis needed until crop matures. Some movement
of weevils noted, but generally below normal. (pp. 989, 990, 1000). CABBAGE
LOOPER increasing in areas of Arizona and New Mexico, ranged light to heavy in
Georgia and Mississippi, and "ragging' leaves in Coastal Plain of South Carolina.

WEATHER BUREAU 30-DAY OUTLOOK
MID-AUGUST TO MID-SEPTEMBER 1963
The Weather Bureau's 30-day outlook for the period from mid-August to mid-September
calls for temperatures to average below seasonal normals in the northeast quadrant
of the Nation with coolest weather over the Great Lakes and northern New England.
Above normal averages are predicted for the western third of the country and also
along the Gulf and South Atlantic coasts. In areas not specified, near normal
temperatures are indicated. Rainfall is expected to exceed normal in a broad
zone from the Northern Plains eastward to New England and southward to the
Tennessee Valley, as well as in the far Southwest. Subnormal amounts are antic-
ipated over the Southern Plains and central Rockies and also along southern
portions of the Atlantic and Pacific coasts, with near normal precipitation in
the remainder of the Nation.
Weather forecast given here is based on the official 30-day "Resume and Outlook"
published twice a month by the Weather Bureau. You can subscribe through the
Superintendent of Documents, Washington 25, D.C. Price $4.80 a year, $2.40 a

WEATHER OF THE WEEK ENDING AUGUST 12
Mid-August weather brought unseasonably cool temperatures to much of the Nation
east of the Rocky Mountains. Two surges of Canadian air lowered averages to
considerably below normal in a large area surrounding the Great Lakes; the largest
reported deficiency was 12° at South Bend, Indiana. Numerous daily record lows
were set north and east of a line arcing from Minnesota to Kansas to Georgia.
Some stations had record low maxima; the high on the 18th at St. Louis, Missouri,
was only 60°, Freezing occurred in the central lowlands of Wisconsin. Significant
unseasonably warm weather was limited to the Great Basin; Salt Lake City, Utah,
logged a 6° departure for the period, one of the largest reported. Temperatures
in southern areas of Texas and Florida averaged slightly above normal. A 114°
maximum on the 13th at Needles, California, was the warmest reported temperature.
Precipitation was quite general, though highly variable in amount east of the
Mississippi River and over the southern half of the Great Plains and Rocky
Mountains. Large sections of Texas, Arkansas, Louisiana, New England, Virginia,
Ohio, and the Carolinas received only light showers, and serious drought conditions
continued in Virginia. Phillipsburg, Kansas, had from 5 to 7 inches of rain
which flooded highways around the town on the 12th. On the 14th, Vicksburg,
Mississippi, was swamped by 4-1/3 inches in only 2 hours. Stormy weather gave
measurable rain to the southwest. An extra heavy storm with unofficial totals
of 5 inches caused local flooding near Glendale, Arizona, on the 16th and 17th.
In 45 minutes on the 17th, Thrall, Kansas, had a rainfall of 1.41 inches. On the

M. bivittatus and M. femurrubrum dominant, with some M. sanguinipes also
involved. Habitats included alfalfa, flax and small grains. (Colberg).
MINNESOTA - Annual adult grasshopper survey started on August 12. Observations
in southwest district show threatening to severe populations in eastern Jackson
County. Adequate rainfall and lush plant growth kept movement into corn and
soybeans down in this county. In central district in Sherburne and Morrison
Counties, few fields had 30-60 grasshoppers per square yard. Counts in northern
counties of central district generally 0-5 per square yard. In northwest
district, almost all high counts in soil bank land and roadsides. Kittson
and Marshall Counties have up to 23 per square yard in soil bank land west of
U. S. Highway 75. M. bivittatus dominant in these two counties. Few high count
fields found in southwestern Norman County; M. femurrubrum dominant. Generally,
populations in northwest district ranged 2-4 per square yard. M. bivittatus
gravid and beginning to deposit eggs. (Minn. Ins. Rpt.).
- 978 -
WISCONSIN - Extensive damage to various crops resulting as grasshoppers mature.
Both M. femurrubrum and M. differentialis nearly completed development in
southern counties. Dissection of M. femurrubrum females revealed about 10
percent with egg formation, and mating observed by M. differentialis. Popula-
tions vary considerably, but in general, most abundant in sandier Soiled and
drier areas of State. Populations appear high in southern Dane, Green, parts
of Lafayette, Bayfield, Trempealeau, La Crosse, Sauk, WausShara and Pepin Counties.
Numbers in sections of these counties range up to 80 per square yard, although
average only about 10-30 per square yard. Injury to variety of crops becoming
more evident in heavier grasshopper populated areas. Report from Trempealeau

County feed mill, volume of grasshoppers equaled that of oats being
milled. Reports from Green County indicated that many new seedings of alfalfa
being stripped; 30 percent of leaves in some fields. Noticeable feeding damage
to field corn evident in most of these areas. Also, several fields of alfalfa
in Juneau County stripped. (Wis. Ins. Sur.). ILLINOIS - Grasshoppers heavy in

WEATHER OF THE WEEK ENDING AUGUST 26
Autumn-like weather prevailed early and late in the period northward from the
Ohio Valley and the central East Coast States. Minima approached the freezing
mark in Pennsylvania and northern Michigan; in the former State, Phillipsburg
cooled to 33° on the 25th. Trees were reported beginning to color in northern
Wisconsin. Except for narrow strips of slightly above normal temperatures over
southern New England and from eastern Virginia to western Florida, temperatures
averaged below normal from the central Plains and Mississippi Valley eastward.
Deficiencies of 6° or more were spread from south-central Illinois to northeastern
Ohio and in northeastern Maine,
Above normal averages of Significance were largely limited to the Great Plains
and sections of the central and southern Rockies. The mercury soared to 109° in
Oklahoma and 105° in Kansas; Rapid City, South Dakota, logged maxima in the upper
90's on 3 days.
Except for extreme coastal locales, much of the remainder of the Far West
recorded unseasonably cool averages. A large area from central California over
interior Oregon was deficient from normal by at least 6°. On the 25th, Reno,
Nevada, reported a 31° low.
Over the Far West, precipitation was almost nil from southern areas of Oregon
and Idaho southward. However, up to 4 inches of rain fell in the mountains of
central Arizona. In Utah, Salt Lake City saw its first rain in 61 days on the
25th, and Cedar City was dampened by a shower of over 2 inches on the 19th.
Rainfall was mostly light in the Northwest, though Centralia, Washington, had a
1 hour deposit of 2 inches. Mostly weekend showers in eastern Montana brought
as much as 2.94 inches to Glasgow.
The light precipitation pattern over the Great Plains and Mississippi Valley was
broken by moderate to locally heavy showers in the central and eastern coast of
Texas, much of Illinois, northern Missouri, and eastern Iowa. A rain gage
measurement of 1.21 inches was the result of a 38-minute shower at La Crosse,
Wisconsin, on the 21st. On the 24th, both Dubuque, Iowa, and Moline, Illinois,
received rainfalls of over 2-1/4 inches.
Recurring showers were fairly general over the Southeast, but Apalachicola,
Florida, and Birmingham, Alabama, went without measurable rain. A 24-hour rain

CEREAL AND FORAGE INSECTS
GRASSHOPPERS - OHIO - Melanoplus differentialis ranged from half to full grown
in Brown and Highland Counties, southwest area. Heaviest populations 20-30
per square yard along grassy roadsides and field margins. Minor feeding damage
occurred in field corn. Populations of M. femurrubrum building up rapidly in
southwest, but little economic damage to field crops noted at this time. (Lyon).
MISSOURI - Moderate to heavy populations of Melanoplus spp. continue present in
southwest. Several fields of corn and grain sorghum in area completely stripped
of foliage by M. differentialis. (Munson, Thomas, Wood). WISCONSIN - Migration
into crops other than alfalfa becoming more pronounced as maturation nears
completion. In most instances, M. femurrubrum comprises at least 90 percent of
population, but M., differentialis appears to be increasing percentage-wise this
year. This is important because latter species responsible for greater share of
corn damage. Egg laying expected soon. (Wis. Ins. Sur.). MINNESOTA - Adult
grasshopper survey nearly complete in western half of State. In northwest
district, populations generally noneconomic to light, except in western Norman
County where few fields had counts of 10-12 M. femurrubrum per square yard. In
northeast district, all counts extremely low, only noneconomic populations found.
In west central district, populations generally noneconomic to light. Higher
counts found in scattered fields in Lac qui Parle, Pope, Swift and Chippewa
Counties; counts in threatening range. In central district, counts varied
greatly, but generally noneconomic to light; one alfalfafield in Kandiyohi
County heavily infested and movement to soybeans noted. Wright County had few
fields of alfalfa where counts ranged up to 40-50 per square yard. Scott and
Carver Counties in central district had noneconomic to light counts generally;
however, two high count fields found. Counts in southwest district generally
noneconomic to light, with an occasional field having threatening infestations.
M. femurrubrum dominant, with M. differentialis showing up in moderate numbers in
some fields. In east central district, Anoka, northern Washington and southern
Chisago Counties had high numbers - other counts in district had noneconomic
to light infestations. A red clover field in Watonwan County, south central
district, had counts exceeding 30 per Square yard. (Minn. Ins. Rpt.).
NORTH DAKOTA - Results of 1963 adult grasshopper range survey show 50,760 acres
with threatening infestations and 968,720 acres with light infestations. Counties
involved include Williams, Dunn, McKenzie, Billings, Golden Valley and Slope.
(Brandvik, Wilson). MONTANA - Adult survey during July shows buildup in northern
and southeastern counties. Heavy populations observed in Glacier, Toole and
Liberty Counties, and reports indicate other counties bordering Cascade County
equally infested. In southeastern area, heavy populations noted in Rosebud and
Powder River Counties. In Glacier County, some 200,000 acres found infested in
Two Medicine and Cut Bank Creek drainage north and south of Browning. (PPC, West.
Reg.). UTAH - Grasshoppers serious problem at Fountain Green and still damaging
over approximately 50,000 acres of crop and range land in West Gunnison through
Fayette and Mayfield south to Sevier County line areas of Sanpete County.
(Knowlton, Funk). This outbreak continues over an area of approximately 12,000
acres in northern Sevier County. Limited controls applied over much of large
two-county outbreak area. Grasshoppers very numerous and mating and laying eggs
7 miles southwest of Nephi and on Levan Ridge, Juab County; 80 percent M.
Sanguinipes and 10 percent M. packardii. Sarcophagid fly parasites very abundant,
striking moving grasshoppers west from Nephi. (Knowlton). NEW MEXICO - Nymphs
of several species averaged 20-52 per 100 sweeps in alfalfa checked at Belen and
Los Lunas, Valencia County. (N. M. Coop. Rpt.).
CORN EARWORM (Heliothis zea) - NEW YORK - Remained remarkably scarce in Hudson
Valley. Evidently, moth flight being surpressed by cool temperature. Only one
moth trapped so far, on August 17. (N. Y. Wkly. Rpt., Aug. 19). NEW JERSEY -
None found on sweet corn at New Market, Middlesex County. (Ins.-Dis. Newsltr.,
Aug. 20). DELAWARE - Sharp increase in adults occurred in blacklight trap
collections in Sussex County. (Burbutis, Evans). MARYLAND - Moth numbers
increasing steadily in blacklight traps in Queen Annes and Worcester Counties.
(U. Md., Ent. Dept.). OHIO - Survey of sweet corn producers in central and
= 1006 -
southern areas revealed that little economic damage has occurred. Few larvae
present in ear tips. Most growers have been treating since early July. Adult
flights have been low. (Lyon, Schurr). MICHIGAN - No adults collected to
August 23, but a general flight considered imminent for coming week; previous
records show that appearance of this pest in State coincides very closely with
cotton leafworm (Alabama argillacea) which was trapped this year on August 21.
(Newman). WISCONSIN - Populations generally very light in most areas, although
few eggs present in southern counties and few half-grown larvae present in sweet
corn in Iowa County. Few larvae also found in Dane and Rock Counties. (Wis.

in southwest and west central areas; counts ranged 1-11 larvae per 100 heads in
infested fields. (Munson, Thomas, Wood). OKLAHOMA - Light populations present
in grain sorghum in southeast, south central, southwest, north central, west
central and northwest areas. (Okla. Coop. Sur.). COLORADO - Larvae present
in some corn ears in Crowley County; 1-3 per 10 ears. Light to moderate popula-
tions present in Montrose County. (Jenkins, Bulla). WYOMING - Larvae averaged
3 per 100 plants in corn fields near Veteran, Goshen County, and in Wheatland
area, Platte County. (Marks). UTAH - Four moths taken in conventional light
trap at Delta, Millard County, night of August 19-20. Reports indicate larvae
common in Delta area and at Nephi, Juab County; 35-65 percent of ears infested.
These counts higher than those encountered from Utah County north. (Knowlton).
ARIZONA - Larvae heavy, 75-80 per 100 corn plants, in Graham and Greenlee
Counties. (Ariz. Coop. Sur.). NEW MEXICO - Damage noticeable on leaves and
tassels of field corn near Estancia, Torrance County. (N. M. Coop. Rpt.).

County; severe damage found in corn in same county. (Ariz. Coop. Sur.).
EUROPEAN CORN BORER (Ostrinia nubilalis) - NEW YORK - Number of moths trapped in
Hudson Valley increased sharply; moths common around sweet corn, but not abundant.
Infestations ranged 0-6 percent on untreated ears. Larvae mostly in tips,
ranging up to third instar, On plants still in whorl stage, infestation ranged
up to 10 percent by August 16. (N. Y. Wkly. Rpt., Aug. 19). NEW JERSEY -
Difficult to find on field corn in State. (Ins.-Dis. Newltr., Aug. 20).
DELAWARE - Adult populations, as indicated by blacklight trap collections, remain

from southern counties to north in western area. Dry weather causing a high
percent of larval mortality. Counts made in known infested fields ranged
1-86 and averaged 21 percent. Adults rather numerous in cotton blooms; first
time this condition observed this season. Conditions favorable for weevil
increase; some boll injury occurring in heavily infested fields. (Locke).

COOPERATIVE ECONOMIC INSECT REPORT
HIGHLIGHTS
Grasshopper survey in 46 Colorado counties indicates lowest level of infestation
since 1959, and results of survey in South Dakota show a substantial buildup in
both crop and range land. Grasshoppers causing severe damage to alfalfa in
Squaw Valley, Elko County, Nevada, and damage continues in areas of Juab,
Sanpete, Millard and Sevier Counties, Utah. (p. 1041).
Major outbreak of CORN EARWORM occurring on soybeans in southeast Arkansas;
activity increasing in several States. (pp. 1041, 1042). Second-generation
EUROPEAN CORN BORER moth flights peaked in Minnesota, Wisconsin and Ohio; larval
activity increasing in Maryland and Delaware. (p. 1042). SOUTHWESTERN CORN BORER
infestations general over northern half of Louisiana; heavy in some late-planted
corn. (p. 1043). WESTERN CORN ROOTWORM spread rapid in Minnesota; problems
expected on corn in next few years. NORTHERN CORN ROOTWORM adults heavy in
continuously grown corn plots at Hoytville, Wood County, Ohio. (p. 1043). TWO-
‘SPOTTED SPIDER MITE present on corn in all areas of Colorado; populations vary
considerably due to recent rains. (p. 1044).
ALFALFA CATERPILLAR activity increasing rather generally on alfalfa. (p. 1044).
Severe infestations of a CHINCH BUG (Blissus leucopterus insularis) reported on
St. Augustine grass lawns in areas of Louisiana, and several CATERPILLARS
heavy and damaging soybeans in southern half of State. (pp. 1041, 1046-1047).
Serious infestations of ORIENTAL FRUIT MOTH building up in untreated peach
orchards near Barnesville, Belmont County, Ohio, and larvae heavy in areas of
Maryland and Alabama. (p. 1047). PEACH TREE BORERS causing extensive damage to
untreated peaches in Lee, Macon and Elmore Counties, Alabama. (p. 1048). POTATO
TUBERWORM found in Monroe County, Michigan; first time in recent years that
species has caused serious economic loss to potatoes in State. (p. 1049). Larvae
of BANDED CUCUMBER BEETLE heavy in many Louisiana sweetpotato fields, with
controls unsatisfactory. CABBAGE LOOPER becoming more prevalent and damaging to
cole and other crops in several States. (p. 1050).
BOLLWORMS continue as major pest of cotton rather generally; large increases
noted in parts of Arizona. COTTON LEAF PERFORATOR continues serious problem on
cotton in Yuma, Pinal and Maricopa Counties, Arizona. (pp. 1051, 1052). High
counts of LYGUS BUGS continue to be found on cotton in areas of California and
Arizona. (pp. 1052, 1053).
Aerial surveys for GYPSY MOTH defoliation disclose more extensive areas of
defoliation in Vermont and New Hampshire and less defoliation in Maine than in
1962; totaled 12,020 acres in Vermont, 8,345 acres in New Hampshire and 1,970
acres in Maine. No gypsy moth adults trapped in Michigan in 1963. (p. 1054).
Several species of MOSQUITOES a serious provlem in Maricopa, Pinal and Pima
Counties, Arizona, and buildups noted following recent rains in McKinley,
Bernalillo, Valencia and Dona Ana Counties, New Mexico. (p. 1056). VESPID WASPS
constitute major insect problem in Rhode Island. (p. 1059).
DETECTION
EUROPEAN EARWIG collected for first time in Michigan. (p. 1059). New county
records of significance were WESTERN CORN ROOTWORM in Blue Earth, Dakota, Goodhue,
Olmsted and Redwood Counties, Minnesota (p. 1043); LOCUST LEAF MINER in Lake and
McHenry Counties, Illinois (p. 1055); and JAPANESE BEETLE in Carter and Simpson

WEATHER OF THE WEEK ENDING SEPTEMBER 2, 1963
Maximum temperatures to 100°early in the week in the Dakotas gave way to a period
of cooling as Canadian air pushed its way over the Nation from the northern
Rockies to the East Coast. Final day (September 1) maxima in Montana were as
low as 61° at Billings and weekly averages over the northern Great Plains were
deficient from normal by as much as 6° Temperatures were mostly cool all week
northward from the central Atlantic States and lower Ohio Valley and period
averages reached to 6° below normal from Illinois to Virginia and New York.
Roanoke, Virginia, heated to only 69° on the 26th. Daily highs exceeded 90°
throughout much of the Gulf States; Oklahoma and Arkansas resulted in averages
to 5° above normal. Before the cooler air reached Arkansas on the 29th,
Ft. Smith and Little Rock experienced maxima exceeding 100° on three days. The
high soared to 106° on the 26th and 28th at the former community, and to 107°
on the 28th at the latter.
Near or below normal temperatures over much of the Far West were partly due to
cloudy skies and quite general shower activity. However, very little rain fell
in California, the Pacific Northwest and northern Montana where weekly departures
were slightly above normal; some freezing early in the week caused little damage
in Nevada. General showers over much of the Rockies and plateau of the Far West
deposited some moderate to heavy amounts locally. Brigham City, Utah, received
its first measurable rainfall since June 24. An August precipitation total of
over 10 1/2 inches at Payson, Arizona, set an all time high record for any month
as much of that State continued to receive nearly unprecedented rains. Much of
the northeast quarter of the Nation had a mild dry week; most areas had weekly
totals of one inch. Totals less than one-half inch covered extensive areas from
the central Atlantic States into Wisconsin and Missouri, southern Georgia, and
eastern Florida and most of Louisiana and southern and central Texas. Heavy
showers were moving into Wisconsin as the period closed. Large areas of the
Great Plains, upper Mississippi Valley and the Gulf Coast from Mississippi to
Key West, Florida, and the southern Appalachians and Tennessee Valley had
general rains over one inch with local areas receiving excessive totals. A
weekly total of 6.43 inches fell on the 29th and 30th at Mobile, Alabama.
Nashville, Tennessee, had a 12-hour drenching of 5.22 inches by 6 a.m. on the
29th and Shelbyville, Tennessee, measured 8.30 inches during the week. Many
stations in eastern Nebraska and western Iowa had totals of 2 inches. (Summary
supplied by U.S. Weather Bureau).

CEREAL AND FORAGE INSECTS
GRASSHOPPERS - WISCONSIN - Populations little changed; 75 percent of Melanoplus
femurrubrum females with eggs in central and southern areas. Populations fluc-
tuate, 2-40 per square yard in Columbia, Marquette, Waushara, Portage, and
Waupaca County area where grasshoppers apparently consistently high. Damage
noticeable in this area, but not alarming in many fields. Disease, parasites
and predators common. (Wis. Ins. Sur.). MINNESOTA - Adult grasshopper survey
completed. Populations in southeast and south central districts quite scattered
and localized. Counts per square yard 0-50, with most fields rated noneconomic
to light. Higher counts ranging threatening or better found in Houston, Goodhue,
Wabasha, Rice and Dakota Counties. M. femurrubrum dominant species by far. M.
differentialis, and at times M. bivittatus, can be found, but never exceeding 10
percent of grasshopper population. Fungus disease noted in grasshoppers in some
fields. Blister beetles, grasshopper egg predators, found but populations
generally low. (Minn. Ins. Rpt.). SOUTH DAKOTA - Adult grasshopper survey com-
pleted. Results show a substantial buildup in both cropland and rangeland.
Degree of infestation on rangeland and acres infested by counties as follows:
Custer, 64,640 threatening and 34,560 light; Dewey, 14,060 threatening and 67,220
light; Fall River, 43,400 light; Haakon, 24,960 threatening and 131,840 light;
Harding, 11,520 threatening and 64,640 light; Meade, 9,600 threatening and 204,800
light; Pennington, 12,800 threatening and 46,720 light; Shannon, 17,939 threatening
and 86,801 light; Ziebach, 6,300 threatening and 39,480 light. Cropland infesta-
tion principally in central part of State; area of infestation extends from
Nebraska line on south to North Dakota line on north; also, isolated cropland
area infested in northwestern part of State that has higher population than pre-
vious years. (Burge, Zimmerman). KANSAS - Survey conducted August 21 and 22 in
central and western areas (including Clay, Mitchell, Osborne, Rooks, Ellis, Trego,
Ness, Lane, Scott and Rush Counties). Populations on all rangeland generally
very low, never exceeding 3 per square yard. Roadsides supported only moderate
populations, ranging 3-10 per square yard. Melanoplus spp. dominant in roadside
habitats, with M. femurrubrum being most abundant. Rangeland supported slant-
faced species primarily. Orphulella pelidna and O. speciosa dominant in central
counties and Opeia obscura dominant farther west. Occasional band-winged species
encountered, but sporadic and not of economic consequence. (Brusven, Knutson).
COLORADO - Grasshopper survey in 46 counties indicates lowest level of infestation
since 1959. Aulocara elliotti, Amphitornus coloradus, Melanoplus sanguinipes and
M. bivittatus present at economic levels on 37,500 rangeland acres (averaging 25
per square yard) in Boulder and Larimer Counties. In Archuleta County, 2,400
rangeland acres had 20 per square yard; principal species Camnula pellucida, M.
Sanguinipes and M. bivittatus. In northeast, populations concentrated in road-—
Sides where moisture available to annual growth; principal species M. bivittatus,
M. femurrubrum and M. differentialis; drought influenced conditions. Severe dry
conditions in southeast reduced populations below economic levels. (Colo. State
Dept. Agri., PPC). Grasshoppers collected from Boulder-Larimer County infested
area for research purposes parasitized and diseased 40-75 percent; mainly with
Scarcophaga sp. and bacterial disease. (Ferkovich). UTAH - Grasshopper damage
continues in several large areas of eastern Millard County, southern Juab County,
northern and southern Sanpete County and northern Sevier County. (Knowlton).
NEVADA - Grasshoppers, predominantly M. sanguinipes and M. packardii, heavy (60-
80 per square yard) and causing severe damage to alfalfa in Squaw Valley, Elko
County; controls being initated. (Earnist).
CORN EARWORM (Heliothis zea) - LOUISIANA - Ranged 6-24 per 30 feet of row on
soybeans in St. Landry, Avoyelles and West Baton Rouge Parishes; lower generally
in Tensas, Madison and East Carroll Parishes. (Newsom). ARKANSAS - Major out-
break on soybeans occurring in southeast. Majority of fields checked in Lincoln
and Desha Counties had economic infestations. Highest counts found ranged 125-
150 larvae per 30 row feet. A few higher counts reported. Most counts much
lower. Also reported on soybeans in Logan County, west central area. Extremely
heavy moth flights in all areas could result in outbreaks in other soybean-pro-
ducing areas. (Ark. Ins. Sur.). Range per 30 feet of row in Lonoke County 0-8
- 1042 -
compared with 0-18 previous week; 8 of 15 fields infested. (Sharp). Counts on
sorghum in Lincoln County, southeast, ranged 75-80 per 100 heads. (Ark. Ins. Sur.).
OKLAHOMA - Counts per 10 sweeps O-10 in Beckham County alfalfa and 3-6 in Choctaw
County. Counts per 100 sorghum heads 150 in Marshall County and 25-50 in
Kingfisher County. Counts of 36 per 100 terminals found on peanuts in Bryan
County and 5 per 10 feet of row on soybeans in Wagoner County. (Okla. Coop. Sur.).
KANSAS - Reports received of feeding damage to sorghum whorls in Barber County,
south central, and soybeans in Cherokee County, southeast. (Gates). MISSOURI -
Counts in soybeans in northeast ranged O-11 per 100 sweeps; counts in alfalfa
0-14 per 100 sweeps. (Munson, Thomas, Wood). MINNESOTA - Low numbers in field
corn in few southeast and south central district fields. (Minn. Ins. Rpt.).
WISCONSIN - Eggs becoming more common in silks of sweet corn in southern counties;
populations light in most areas. (Wis. Ins. Sur.). MICHIGAN - Three adults taken
in a blacklight trap in southern Monroe County; infestations expected. (Baker,
Newman). OHIO - Small number of adults taken in blacklight traps at Riple,
Wooster, Hoytville and Vickery. Egg masses expected on late sweet corn soon.
(Schurr). NEW YORK - Continues scarce or absent on sweet corn in Hudson Valley.
No additional adults trapped at Poughkeepsie after one of August 17. No larvae

pupae held in cartons since July. Canadian-style weather evidently controlling
pest. (N.Y. Wkly. Rpt., Aug. 26). MARYLAND - Moths increasing steadily in black-
light traps in Queen Annes and Worcester Counties; eggs light on soybeans August
29 in Talbot and Wicomico Counties. (U. Md., Ent. Dept.). DELAWARE - Adult
collections in a blacklight trap in Sussex County totaled 1,252 for last 8 nights
(Aug. 22-29), indicating extremely heavy moth flights in this area. (Burbutis,
Evans). VIRGINIA - No infestations of soybeans observed in King George,
Westmoreland, Richmond, Essex, Middlesex, Gloucester and King and Queen Counties.
Examination of corn ears in same area revealed lighter than usual infestation in
fields. (Rowell, Amos). Continued to increase on Eastern Shore and untreated
corn ears 100 percent infested. (Hofmaster). NORTH CAROLINA - Becoming fairly
abundant on soybeans locally in Wake County. (Brim). GEORGIA - Light on heads of
millet and grain sorghum; light to moderate in whorls of grain sorghum and millet;
and light to moderate on soybeans in middle and southern areas. (Johnson). NEW

(N.M, Coop. Rpt.). UTAH - Moderately numerous on corn at Green River, Emery
County. (Knowlton). NEVADA - Medium to heavy on corn, especially ears, in southern
Lincoln and Nye Counties and Clark County. (Bechtel).
EUROPEAN CORN BORER (Ostrinia nubilalis) - NEW YORK - Moth catches continue in
trap at few to several per night in Hudson Valley. Larvae, up to fifth instar,
found in sweet corn ears by August 24; treated corn clean. Infestation of
untreated tasseling planting about 15 percent. Borers chief reason for current
light silk treatment program 5 days apart. (N.Y. Wkly. Rpt., Aug. 26). MARYLAND -
Second-generation larvae increasing in field corn in all sections. (U. Md., Ent.
Dept.). DELAWARE - Infestation in field corn ranges 10-50 percent; heaviest in
Sussex County. Fresh egg masses still common on corn in many areas of State and
adult flights remain very high; light trap collections August 22-29 totaled 406.
(Burbutis, Evans). OHIO - Second-generation adult flight reaching peak at
Wooster, Wayne County. (Schurr). WISCONSIN - Fresh egg masses still being found;
larvae becoming more common in ears of sweet corn. (Wis. Ins. Sur.). MINNESOTA -
Peak moth flight occurred during week of August 19-23 according to light traps.
Relatively high numbers collected at Worthington and Fergus Falls. Development
in southeast 13 percent first instar, 13 percent second instar, 35 percent third

Lincoln County; Las Vegas, Moapa and Virgin Valleys, Clark County; and Pahrump
Valley, Nye County. (Bechtel).
SOUTHWESTERN CORN BORER (Zeadiatraea grandiosella) - LOUISIANA - Infestations
general over northern half of State; heavy on some late-planted corn. Infestation
of stalks 100 percent in one late-planted field in Bossier Parish; averaged 6
larvae per plant. About 10 percent pupae, 15 percent diapausing larvae and all
larval stages present. (Newsom).
SUGARCANE BORER (Diatraea saccharalis) - LOUISIANA - Marked increase in egg
deposition by third-generation moths during last half of August. Few moderate
to heavy infestations developing in some areas. (Newsom).
SORGHUM WEBWORM (Celama sorghiella) - GEORGIA - Light on heads of millet and
grain sorghum. (Johnson). ARKANSAS - Ranged about 75-80 per 100 sorghum heads in
Lincoln County. (Ark. Ins. Sur.).
A NOCTUID (Septis apamiformis) - WISCONSIN - Prevalent on wild-rice being harvested
in Three Lakes area, Oneida County. (Wis. Ins. Sur.).
SORGHUM MIDGE (Contarinia sorghicola) - NEW MEXICO - Light in Curry County sorghum
fields; averaged about 3-5 adults per 100 sweeps in fields checked. (N.M. Coop.
Rpt.).
WESTERN CORN ROOTWORM (Diabrotica virgifera) - MINNESOTA - Blue Earth, Dakota,
Goodhue, Olmsted and Redwood Counties added to growing list of counties infested
by this species; populations low. Species has moved rapidly across State.
Species first found in extreme southwestern corner of State in 1961 and can now
be found in Dakota County on eastern border. Corn growers can expect to have
problems with this rootworm in next few years. (Minn. Ins. Rpt.). KANSAS -
Populations of rootworms, primarily this species, decreasing rapidly in north
central and northeast areas. (Burkhardt, Peters).
NORTHERN CORN ROOTWORM (Diabrotica longicornis) - WISCONSIN - Adults common on
silks of corn, in alfalfa fields and in roadside grasses in southern counties,
(Wis. Ins. Sur.). OHIO - Heavy adult populations observed in continuously grown
field corn plots at Hoytville, Wood County. Adults 8-45 per ear; actively feed-
ing on silks. Very few adults observed in rotated corn fields one-half mile from
continuously grown corn plots. (Lyon). Adults feeding on silks of untreated corn
near Ottawa, Putnam County. Only outer rows infested. (Gerber, Aug. 22). Adults

COOPERATIVE ECONOMIC INSECT REPORT
HIGHLIGHTS
GRASSHOPPER adult survey on cropland in North Dakota showed general infestation
up in light rating from 1962, but slightly down in threatening rating; however,
severe damage present in scattered fields except in eastern third of State.
Grasshoppers migrating in many areas of Wisconsin; mating and egg laying
increased. Damage to crops also reported to have increased. CORN EARWORM
infested majority of soybean fields in upper Arkansas River Valley, Arkansas.
Egg deposition still heavy in cotton in area and younger soybeans may become
infested. Also, heavy and defoliating soybeans in parts of Mobile County,
Alabama, and ranged medium to heavy on same crop in delta counties of Mississippi.
(p. 1073). NORTHERN CORN ROOTWORM adults feeding on corn silks in areas of

WEATHER BUREAU 30-DAY OUTLOOK
SEPTEMBER 1963
The Weather Bureau's 30-day outlook for September calls for temperatures to
average below seasonal normals over the eastern half of the country except for
near to above normal along the gulf and south Atlantic coasts. Above normal
averages are predicted over the western third of the Nation and near normal in
unspecified areas, Rainfall is expected to exceed normal in a broad band extend-
ing from the Southern Plains through the Ohio Valley into the Northeast. Sub-
normal amounts are anticipated west of the Continental Divide and along the
gulf coast. In the remainder of the country, precipitation should not depart
greatly from normal,
Weather forecast given here is based on the official 30-day "Resume and Outlook"
published twice a month by the Weather Bureau. You can subscribe through the

WEATHER OF THE WEEK ENDING SEPTEMBER 9
At the beginning of the week, high pressure dominated the weather over the eastern
third of the Nation. Skies were clear and winds were calm or light. A low
pressure area, centered over central South Dakota, caused general cloudiness from
the eastern slope of the Northern Rockies to Lake Michigan and southward over the
Central Plains. Rain fell over much of the Dakotas, Minnesota, and Iowa.
Scattered thunderstorms occurred in Kansas. Variable cloudiness prevailed from
the Rocky Mountains westward to the Pacific. As the low pressure area moved
eastward, it triggered a few tornadoes in southern Wisconsin and heavy thunder-
storm activity from Michigan to Kansas. Hail fell from some of the thunderstorms.
Cloudiness and severe weather increased eastward to New England. Sunshine pre-
dominated over the western, central, and southern portions of the country. By
Saturday, the cold front associated with the low pressure area had moved to the
Atlantic and storm activity was limited to some cloudiness along the northern
Atlantic seaboard and a few showers farther south. Fog, which developed in the
cool air mass, blanketed much of the Ohio Valley, the Lake region, the Appalachians,
and parts of the Atlantic coast and New England on two or three forenoons over
the weekend. In most areas, the fog dissipated by noon.
Scattered thunderstorms dumped an inch or more of rain at spots in the north-
central Rockies, the west-central and southern Plains, and Florida on Saturday
morning. But most of the Nation enjoyed pleasant weekend weather. Most areas

COTTON INSECTS
BOLL WEEVIL (Anthonomus grandis) - NORTH CAROLINA — Punctured all squares examined
in a Harnett County field on August 30. (Vinson). SOUTH CAROLINA - Young bolls

northern counties, especially Fayette, Marion, Lawrence and others caused
considerable damage to half and three-quarter grown bolls; 1-6 bolls per stalk
noted damaged in some fields. Dry weather caused squares and small bolls to
shied; weevils used larger bolls for food and egg laying. Controls ended in
practically all cotton-producing areas as harvest underway in most counties.

HAWAIIAN INSECT NOTES
The following notes on Hawaii insect conditions were presented at the 692nd
meeting of the Hawaiian Entomological Society held on August 12, 1963.
SPOTTED GARDEN SLUG (Limax maximus) was found for the first time on the Island of
Maui on July 11, 1963. A large specimen was collected by Nobuo Miyahira at
Haleakala acres, crawling on the outside wall of a building. On Oahu, this species
was first collected in upper Manoa Valley in 1949. Det. by C, E. Pemberton.
(Mabel Chong).
SCARABS (Onthophagus catta and Copris incertus) - Investigation of damage to
roofing paper on a home in Pupukea, Oahu, during early July showed these 2 species
to be responsible. Approximately 90 percent of beetles involved were O. catta.
The section of roof damaged was part of a sun deck that had been railed off and
in which had been placed a large electrocuting-type light trap. Numerous dead
beetles were piled up in the corners. Live beetles had moved to the corners and
chewed through roofing made of 3 layers of 40# roofing felt and a top of 70#
fiber glass felt, with asphalt binder between each layer. The beetles had chewed
holes of 2-3 inches in diameter, exposing the lumber underneath. (H. Nakao).
AN ENSIGN SCALE (Arctothezia occidentalis) - Several specimens (one mature female
and 4 pre-adult and nymphal females) were collected at 8,000 feet elevation on
rim of Haleakala Crater, Haleakala National Park, Island of Maui, on July 15,
1963. The specimens were found associated with roots of a bunchgrass (Agrostis
sandwicensis) , which is common in the area. This is a new insect record for
Hawaii, and only the second ortheziid scale known to be established in Hawaii;
the other being GREENHOUSE ORTHEZIA (Orthezia insignis). (J. W. Beardsley).
A ROOT APHID (Rhopalosiphum rufiabdominalis) collected from roots of yellow nut
sedge (Cyperus esculentus) near Pepeekeo, Hawaii, on May 23, 1963. This is a new
island record and a new host plant record for this species previously known in
the State only from Oahu on Cyperus sp. (J. W. Beardsley).
A MANTID (Tenodera australasiae) - Adult and an empty ootheca were collected on
Molokai during June 1963; the first at the airport and the second at Mapulehu,
25 miles distant. An ootheca, containing viable eggs which hatched in Honolulu,
was collected near Lahaina, Maui, on July 11, 1963. These constitute new island
records for T. australasiae, which was previously known only from Oahu.
(J. W. Beardsley) .
A MYMARID (Patasson calendrae) - This minute hymenopterous parasite of eggs of
Sphenophorus spp.is being reared from parasitized eggs received from F. A, Bianchi
in Columbia, Missouri. It is hoped that this parasite will become established in
Hawaii and aid in the control of a billbug (Sphenophorus venatus vestitus) ,
which has damaged zoysia lawns and sugarcane seedlings in the State.
(J. W. Beardsley).
A CHRYSOMELID (Octotoma scabripennis) was recovered from lantana in the White
Sands Beach area, Kailua-Keauhou Road, Kona, Hawaii, on July 13, 1963, and was
subsequently discovered at Kahauloa, Kona, where it was the dominant species on
one lantana clump. This latter location was the release point for a cerambycid
(Plagiohammus spinipennis) in late December 1960. The presence of O. scabripennis
in both locations indicates that the species is well adapted to both dry and wet
habitats. O. scabripennis was first released in 1902, but apparently failed to
become established. It was reintroduced in 1954 and 1955 from Mexico; recovery
9 years later was approximately 18 miles from the nearest release point.
(Ca JeeDavis)>
PUNCTUREVINE WEEVILS (Microlarinus spp.) - Shipments of the stem feeding species,
M. lypriformis, were received from California on July 7, 1963, and released at
west Kauai for control of the weed pest, Tribulus terrestris. Riker mounts
- 1094 -
showing seed damage to native puncturevine, Tribulus cistoides, by the seed
feeding species, M. lareynii, were exhibited. (C. J. Davis).
SOUTHERN GREEN STINK BUG (Nezara viridula var. smaragdula) - In addition to
infestations found between Kailua and Keauhou, Kona, this pest was also found at
Napoopoo, Honaunau, Hookena, Hilo and at Paauhau, Hamakua Coast. Chemical
eradicative measures discontinued; biological control station established at
Honaunau through cooperation of City of Refuge National Historical Park. Other
stations are being organized in Hilo and the Hamakua Coast. An appropriation of
$13,300 was made from the Governor's contingent fund to increase laboratory
production and distribution of parasites of this pest on Oahu, Hawaii and Kauai.
Maui is also included in the program. (C. J. Davis).
A CERAMBYCID (Plagithmysus newelli) - Specimens of this interesting endemic
species were reared from Nicotiana glauca collected at Auwahi, Maui, by Nobuo
Miyahira. K. Maehler bred P. newelli from the same host on Maui in 1948 and
this was the first record of this native beetle breeding in an exotic host. The
native host of this species is not known. (Ceatdie Davis) rs

Spring and Early Summer
Observations on the Alfalfa Weevil and Other Forage Crop Insects
in Massachusetts-1963
F, R. Shaw and W. Ziener
Alfalfa weevil (Hypera postica) has caused extensive damage in some untreated
alfalfa fields in Massachusetts in 1963. Population of 2,440 individuals per 100
standard sweeps with a 15-inch net has been recorded.
The following observations are based on population studies made primarily in
Hampden and Hampshire Counties. We first observed adults and first and second-
stage larvae on May 1 but did not find overwintering eggs. By May 8, up to ten
adults and four larvae per 100 sweeps were recorded. On May 17, the first egg
punctures were found in stems; these contained an average of 8.0 eggs. The same
day 28 adults and 13 larvae, mainly third instar, were obtained per 100 sweeps.
On May 22, the populations had increased up to 44 adults and 90 larvae per 100
sweeps, with most of the larvae being third and fourth instars. Up to 37 adults
and 477 larvae per 100 sweeps were obtained on May 31. The first pupae in Hampden
and Hampshire Counties were noted on the same day. Pupation in Bristol County
was noted on May 27 and in southern Berkshire County on June 5,
The maximum population of alfalfa weevil ever recorded in the State, 2,440
specimens per 100 sweeps, was found on June 5 in Berkshire County. This total
included 39 adults, 1 pupa, 4 prepupae, 4 first instar, 189 second instar, 984
third instar and 1,219 fourth instar. On the same day, in a count of one-
hundred stems, 83 egg punctures were found with an average of 10.6 eggs per
puncture. Sixty-seven percent had one, twenty-four percent had two and nine
percent had three punctures per stem.
Newly emerged adults were observed on June 13 in Hampden County. Of 29 females
captured that day, 18 were old and gravid representing the overwintering brood
and 11 lacked developed eggs and were obviously of the new generation.
We recorded also the presence of other insects injurious to forage crops and some
of the more important beneficial arthropods as well. A total of 11,688 insects
and insect relatives was determined and the data are summarized below.

Miscellaneous Insects: 2:
Includes grasshoppers, sawflies and caterpillars
Beneficial Arthropods:
Lady beetles - Coccinellids 136
Spiders and harvestmen iy aak
Nabis ferus 0.8
Chrysopids Oj:
Of particular note is the great increase in the alfalfa weevil. In 1961, this
weevil represented only 1.4 percent of all insects; in our 1962 fall survey it
comprised 1.8 while in 1963 it rose to 38 percent.
The potato leafhopper (Empoasca fabae) thus far has not been particularly abundant.
It was first noted in the area on May 16 in Hadley, Hampshire County.
Spittlebug nymphs were first noted on May 8. In Bristol and Berkshire Counties,
heavy infestations have been found. In Hampden, Franklin and Hampshire Counties,
their abundance was about average.
Alfalfa Weevil Parasite Established in Massachusetts
In May 1962, we released Bathyplectes curculionis in two alfalfa fields in
Massachusetts. One site was in Franklin County, the other in Bristol County.
The parasites were furnished to us by James Huggans and Dr. Carl Blickenstaff,
Alfalfa Weevil Investigations, ARS, USDA.
This spring we obtained larvae of the alfalfa weevil from the two release sites.
These were sent to James Huggans who reared them and determined the percent
parasitism. From the site in Franklin County we obtained 5.6 percent parasitism
and 2 percent from the Bristol County release.
This recovery of parasitized weevil larvae in 1963 demonstrated the ability of
released Bathyplectes to attack the 1962 generation of weevil larvae and to
survive the 1962-63 winter season in Massachusetts. -

WEATHER BUREAU 30-DAY OUTLOOK
MID-SEPTEMBER TO MID-OCTOBER 1963
The Weather Bureau's 30-day outlook for the period mid-September to mid-October
calls for temperatures to average above seasonal normals over the eastern half of
the Nation, except near normal in the Tennessee Valley and over the Middle and
South Atlantic States. Below normal temperatures are indicated for the western
half of the country except near to above normal in southern portions. Precipita-
tion is expected to exceed normal along the Atlantic Seaboard and over the north-
west quarter of the Nation. Subnormal amounts are predicted for the Great Lakes
region, Gulf States, and far Southwest. In unspecified areas rainfall should be
near normal.
Weather forecast given here is based on the official 30-day "Resume and Outlook"
published twice a month by the Weather Bureau. You can subscribe through the
Superintendent of Documents, Washington, D.C, 20250. Price $4.80 a year,- $2.40
a half year.
WEATHER OF THE WEEK ENDING SEPTEMBER 16
Mild temperatures and abundant sunshine prevailed over most of the Nation on
Monday, September 9. Some early morning fog covered parts of the Ohio River
Valley and eastward, but this was mostly dissipated by midforenoon. Scattered
thunderstorms produced light showers from Oklahoma to Nebraska. A few isolated
thunderstorms occurred along the gulf in the afternoon. By Tuesday, a cold front
was pushing across the Northeast, followed by cooler, less humid air. Typical
summertime, afternoon thunderstorms built up in the western mountains and in the
warm moist air along the gulf. Pressures fell over the middle of the Nation on
Wednesday and early morning thunderstorms dumped generous rains over Iowa,
northern Missouri, and some nearby areas. As the disturbance moved eastward,
the rains spread to Wisconsin, Illinois, and the Lakes region. By Thursday,
temperatures were tumbling in the Northern Border States and cloudy skies and
thunderstorms covered the northeast quarter of the Nation. By the weekend, high
pressure and scattered clouds prevailed over most of the eastern half of the
Nation. An elongated low pressure area paralleled the Atlantic coast. This area
intensified, causing cloudiness, moderate to heavy rain, and some strong winds
from New England to the Carolinas. Weekend showers and thunderstorms also fell
along the gulf coast in connection with a stationary front that stretched from
Texas to northern Florida. (Continued on page 1114).

CEREAL AND FORAGE INSECTS
CORN EARWORM (Heliothis zea) - IDAHO - Infestations in sweet corn in southwest
heavy, ranging 50-100 percent in individual fields. A blacklight trap operated
within 100 yards of one field (about 85 percent infested) attracted no moths for
most of nights in July and August, with a top catch of 9 for any 3 successive
nights. (Scott, Bechtolt). ARIZONA - Larvae causing some damage to field corn in
Yuma and Maricopa Counties; averaged 3 per plant in infested Maricopa County
fields. (Ariz. Coop. Sur.). COLORADO - Larvae 2-10 per 10 ears of field corn in
Montezuma, Larimer, Weld and Yuma Counties. Larvae leaving ears to pupate. In
southeast, second brood of moths active. (Jenkins, Schweissing). NEBRASKA - A 5-
percent infestation occurs in Lincoln County field corn. (Pruess). MICHIGAN -
Early reports from blacklight trap catches indicate a rather general flight of
adults in sweet corn areas of Lower Peninsula on evening of September 11; earlier
collections light and spotty. This is first season during recent years when
general flights did not occur in State early enough to coincide with silking of
considerable late sweet corn acreage. Young larvae found infesting small per-
centage of a Monroe County sweet corn field September 9; reported very light in
Wayne County. (Newman, Janes, Kidd). DELAWARE - Adult collections in blacklight
trap remain high in Sussex County. (Burbutis). MARYLAND - No increase in eggs
noted on soybeans in Dorchester and Wicomico Counties. Only light pod injury by
small larvae occurred in Dorchester and Wicomico Counties. (U. Md., Ent. Dept.).

controls difficult. (Buttram, Bouler). ARKANSAS - Averaged 30 per 100 sweeps on
alfalfa in Washington County. Of larvae collected from soybeans August 28-
September 3 in Lonoke County, 1 was H. virescens and 128 H. zea. Twenty-nine
larvae collected in Monroe County September 3 were all H. zea. Total of 121
larvae taken from soybeans in Desha County June 26-30 all H. zea. Collections
during September of 1962 in southeast area were all H. zea (238 larvae). Only
prior records of these two species on soybeans show 260 H. zea and 9 H. virescens
collected during July-September 1952. (Ark. Ins. Sur.). Ranged 0-69 per 30 feet
of row of soybeans in Lonoke County compared with 0-89 previous week, Twelve of
15 fields infested compared with 10 of 13 previous week, (Sharp). OKLAHOMA -

tions in corn in Bibb, Peach, Houston and Macon Counties. This is first report
for Macon County. (Brightwell). DELAWARE - Adult collections in blacklight trap
in Sussex County remain high. (Burbutis). MICHIGAN - Egg masses, with a higher
percentage hatched than unhatched, common in Macomb County research plots. Eggs,
first instars and recent feeding injury evident in Ingham County. Some larvae
found in sweet corn ears in southern counties; adults still being taken at black-
light traps. (Evans, Janes, Kidd, Newman). MINNESOTA - Stalk breakage very
noticeable in west central district where infestations highest. (Minn. Ins. Rpt.).
SOUTH DAKOTA - Development advanced to second and third instars in extreme
northern areas. (Hintz). NEBRASKA - Infested 40 percent of corn ears in Lincoln
County. (Pruess). Infestations ranged 25-60 percent of fourth and fifth-stage
larvae in Fillmore and Saline Counties. (Bergman).
SOUTHWESTERN CORN BORER (Zeadiatraea grandiosella) - ARKANSAS - Larvae girdling
stalks and boring below ground level in Washington County, northwest area;
lodging showing up. (Ark. Ins. Sur.).
SOUTHERN CORNSTALK BORER (Diatraea crambidoides) - GEORGIA - Light to moderate
infestations on corn in Bibb County. (Brightwell).
= OGi—
WESTERN BEAN CUTWORM (Loxagrotis albicosta) - NEBRASKA - Larvae infesting less
than one percent of corn ears in Lincoln County. (Pruess).

Weather of the week ending September 16 (continued from page 1104)
Rainy weather also prevailed over the Northwest from the Pacific Ocean to the
Rocky Mountains. A few’scattered thunderstorms sprinkled spots in the desert
areas. Weekend thundershowers were general over the Northern Plains. They
produced mostly light amounts of rain. However, from central Nebraska came
reports of heavier amounts. One report, from a vicinity southwest of North
Platte, stated that 7 to 8 inches of rain had fallen. Temperatures averaged
above normal from the Pacific Ocean eastward to the Northern Plains, the Central
Plateau, the Southern Plains and along the Gulf of Mexico. Temperatures
averaged below normal from Iowa and Missouri northeastward to New England and
southeastward to Georgia. Temperature departures ranged from +7° at Boise, Idaho,
and Sheridan, Wyoming, to -7° at Binghamton, New York, and Burlington, Vermont.
The below normal temperatures were produced by the vigorous cold front that
pushed southward across the eastern United States on Friday, dropping temperatures
to 32° or lower at scattered localities from North Dakota, Minnesota, and Iowa,
eastward to New England, to the 40's as far south as the Ohio River, and to the
50's as far south as the Carolinas. in general, above normal temperatures
occurred early in the week followed by much colder on Friday and Satruday. By
Monday, September 16, a warming trend had started over much of the Nation.
Rainfall was generally light from the Pacific Ocean to the Missouri River. Some
exceptions were in northwestern Oregon and in central Texas, where weekly totals
exceed 1 inch, and from Oklahoma to central Nebraska, where several inches of
rain fell over the weekend. Amounts of an inch or more were scattered over the
eastern half of the Nation. A few eastern localities received generous rains
from thunderstorms. Several inches fell along the Virginia coast.
Hurricane Cindy developed on September 16 in the northwestern Gulf of Mexico about
140 miles south-southeast of Galveston, Texas. Moving slowly toward the north and
north-northwest, the ill-defined eye of the storm area passed inland about 8 a.m.,
c.s.t., Tuesday, September 17,midway between Port Arthur and Galveston. Gale
force winds and high tides were reported from the extreme upper Texas and west
Louisiana coastal areas, with winds of hurricane force locally in a few squalls.
Heavy rains were spreading northward through extreme eastern Texas and the
western and northern portions of Louisiana on Tuesday morning. (Summary supplied
by U.S. Weather Bureau).

INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES
NATAL FRUIT FLY (Ceratitis rosa Karsch)
Economic Importance: The earliest record of this tephritid is in the original
description by F. Karsch in 1887 from specimens collected at Delagoa Bay,
Mozambique. By the turn of the century, it was recorded as a pest of economic
importance in Natal Province, Republic of South Africa. Natal fruit fly is now
considered the most common fruit fly of economic importance in Southern Rhodesia,
and it has been reared from fruits from all parts of the eastern districts.
About 1953, after accidental introduction to Mauritius, this fly became i
established and even largely replaced the Mediterranean fruit fly (Ceratitis
capitata (Wied.)) as a pest of fruits. This situation, as to replacement, also
probably occurred in Southern Rhodesia since it is thought that the Mediterranean
fruit fly was more common in that country in previous years.
Hosts: This fruit fly infests most kinds of orchard fruits and a large number
of wild ones. Only nut crops appear to be immune from attack. Included in
those attacked are peach, apricot, apple, quince, guava, citrus, rose-apple,
loquat and an indigenous fruit, Garcinia livingstonei. Of these hosts, peaches
and guavas are particularly favored.
Distribution: Angola, Kenya, Mozambique, Nigeria, Nyasaland, Republic of South
Africa, Southern Rhodesia, Swaziland, Tanganyika, Uganda, and the islands of
Mauritius, Reunion and Zanzibar.
General Distributio: s* Ceratitis rosa Karsch
Tephritidae, Diptera No. 156 of Series
CEIR 13 (38) :9-20-63
= 33) =
Life History and Habits: The Natal fruit fly overwinters in the adult stage and
is able to withstand temperatures as low as 20°F., provided the warming period
comes Slowly. Food, water and shelter are more important overwintering factors
than temperature. Overwintering flies feed on honeydew and require an abundant
water supply. It was discovered that this species is not attracted to traps
during the winter months.
Eggs are laid, 10 to 20 at a time, by the female just below the fruit surface.
The fruit does not need to be damaged before eggs are laid, and eggs may be
deposited in tissues of fruits long before ripening occurs. Where fruits are
still very green, eggs may not hatch and may even be expelled by exudations from
the fruit. Such exudations frequently indicate the presence of the fruit fly.
Eggs usually hatch within four days after oviposition, but under cold conditions
may take longer. Larvae develop rapidly and burrow throughout the tissues of the
fruit. When removed from the fruit, larvae have a characteristic habit of arching
themselves and leaping by sudden straightening. This characteristic is also noted
in Mediterranean fruit fly larvae. There are three larval stages and a prepupal
stage which occupy a total period of about 12 days, which will vary under
different temperature conditions. When full grown, larvae leave the fruit and
pupate below the soil surface. The pupal stage lasts 10-20 days. Emerging adults
seek Shady areas of trees during hotter hours, but are active during morning and
evening hours. Females usually start ovipositing in about 7 days. During
oviposition, females are quite active and may travel considerable distances,
giving rise to a succession of generations appearing in different varieties and
species of fruits as they ripen one after the other. Toward the end of the
fruiting season, there is a large buildup of Natal fruit fly populations. Adults
may live for several months, especially under mild conditions. All stages of the
life cycle are influenced by climatic conditions, developing more rapidly under
hotter conditions. There are about 10 generations a year.
Description: Body principally brown to tawny. Thorax dark brown laterally, the
disc light brown pruinose with short, golden hairs and with a suggestion of a
pair of brown longitudinal stripes, usually ending posteriorly in large spots.
Pleura yellowish, becoming darker ventrally. Scutellum shiny black with a pair
of narrow yellow lines interrupting its expanse. Wing pattern with small, black
markings at base of disc and brown bands apically, mostly unconnected, much as in
Ceratitis capitata (Wied.). Legs yellow, the mesothoracic tibiae of males (only)
with dorsal and ventral brushes of elongated, bluish-black scales. Head,
including antennae, yellow; face whitish without a black spot; no capitate hair
in the males as in capitata. Yellowish abdomen with 2 transverse dark brown
bands. Ovipositor sheath of female shorter than width at its base. Length 4-5
mm. or about three-sixteenths of an inch. (Prepared in Survey and Detection
Operations in cooperation with other ARS agencies. Description of adult furnished

HIGHLIGHTS
A severe NORTHERN CORN ROOTWORM infestation reported from St. Clair County,
Michigan; this represents northernmost problem due to this species in State to
date. (p. 1137). ALFALFA CATERPILLAR continues a problem to alfalfa in many
areas of southern New Mexico, and larvae very numerous on alfalfa in Gila and
Dome Valley, Yuma County, Arizona. ALFALFA WEEVIL severely infested third-
growth alfalfa in Susquehanna County, Pennsylvania, and adults averaged 18 per
100 sweeps in Fremont, Washakie, Hot Springs and Big Horn Counties, Wyoming.

WEATHER OF THE WEEK ENDING SEPTEMBER 23
The third hurricane of the season moved toward the Texas upper coast on Monday,
September 16, preceded by heavy rains along the coast from Galveston, Texas, to
Mobile, Alabama. The storm dumped 15 to 25 inches of rain on some counties in
southeastern Texcs and nearby areas in Louisiana, and lesser amounts farther
inland. Another tropical storm approached the southern California coast. It
produced heavy rains over much of the southern part of that State, over nearby
portions of Arizona, and over the Great Basin. This storm drenched Yuma, Arizona,
with 2.42 inches of rain on Tuesday. That amount is four times the September
normal and is more than two-thirds of the annual normal for Yuma, A low pressure
area that early in the week lay a few hundred miles southeast of Nantucket,
Massachusetts, and a stationary front that extended southwestward to the Florida
Penninsula produced several inches at some locations along the coast and lighter
amounts farther inland. A low pressure area centered north of Winnipeg, Canada,
on Tuesday, moved rapidly northeastward. A trailing front from northern lower
Michigan to the southern Rockies produced a broad band of light rains over the
upper Mississippi Valley, the northern Great Plains and Plateau, and the northern
and central Rocky Mountains. Some very sharp temperature contrasts existed across
this front. At noon Tuesday, Des Moines, Iowa, registered 83° and Spencer, Iowa,
registered 61°. Shortly after noon, Chicago registered 92° but the temperature
tumbled to the 60's after the frontal passage. As the front continued southward,
it dropped temperatures but produced little rain. Tennessee registered no rain.
The dry area, which received no rain or only light sprinkles extended from the
central parts of Illinois, Indiana, and Ohio, southward to southern Alabama and
the coast of Georgia.
Dry, sunny weather prevailed in the wéstern counties of Florida and the north-
western part of the Peninsula, Southern Florida received generous rains from a
low pressure area which covered the eastern part of the Gulf of Mexico. Key West,
Florida, received 10.29 inches of rain during the week. Of the amount, 9.00
inches fell on Thursday and Friday. Temperatures averaged below normal over most
of California and the Great Basin; also along the Gulf of Mexico and from the

FOREST, ORNAMENTAL AND SHADE TREE INSECTS
BARK BEETLES - TEXAS - 403 new Dendroctonus frontalis infestations located on
aerial detection flights over portions of Hardin, Jasper, Liberty, Orange, Polk,
San Jacinto, Trinity and Tyler Counties; 60 percent of spots consisted of
single tree infestations. D. terebrans reported infesting loblolly, longleaf,
and slash pines in Angelina, Houston, Jasper, Liberty, Montgomery, Orange,
Polk, Sabine, San Jacinto, Shelby, Trinity, Tyler and Walker Counties.
Die terebrans severe in some localities within area of current D. frontalis
epidemic, and where populations increased through association with other species.
Infested trees treated on National Forests. Infestations of Ips avulsus,
I. grandicollis and I. calligraphus continued to decline; only small damage
observed. (Williamson; Tex. For. Pest Comm., Aug. Rpt.). ARKANSAS - Ips spp.
still active in some heavily infested spots; largest area involved is 1,200
trees on 50 acres in western section of State, with scattered infestations
in area covering 300 acres. This would be regarded as explosive situation
and might easily develop into fast moving epidemic unless cultural practices
and weather slow down beetle development. Much smaller spots. prevalent in
other areas, D. terebrans quite active in recently harvested spots. Seed
trees will be most vulnerable to attack and economic loss from this beetle.
(Ark. For. Pest Rpt., Sept.). ALABAMA - D. terebrans very active in Marengo
County; killed 25 shortleaf and loblolly pines at intersection of State Highways
10 and 69. Larvae, pupae and adults present. (McQueen). Ips spp. damaged 90
percent of young 3-foot pines in a Mobile County nursery. (Seibels, Bolton).
FLORIDA - Survey during August showed D. terebrans still active in some naval
stores areas, but not to such extent as in 1962. (McCowan). NORTH CAROLINA -
D. frontalis increasing at about normal rate for time of year. Almost inactive
in Mecklenburg County area where infestation very heavy in 1962. Infestations
in Davidson, Randolph and portions of Guilford, Forsyth and Yadkin Counties
appear slightly more severe than earlier in 1963. (For. Pest Newsltr.).
D. frontalis and Ips spp. infestations noted in Warren and Vance Counties, near
Virginia State line; relative abundance will not be known until ground survey
made, (Green). Ips calligraphus light on pines at a location in Robeson County.
(McIntyre, Mount; Sept. 2). PENNSYLVANIA - Ips pini killing white pine on
35-acre tract in Chester County; many trees damaged by construction activity.
(Nichols; Pa. For. Pest Rpt., Aug. 14).
PINE ROOT COLLAR WEEVIL (Hylobius radicis) - NEW YORK - Caused some damage to
Scotch and red pine plantings in northern Fulton County. (Northeast. For.
Pest Rpt.), Sept.))-
PINE BARK WEEVILS - PENNSYLVANIA - Hylobius pales heavy on nursery block of Mugho
pine in Centre County. (Collacott, Sept. 4). ARKANSAS - Increased activity
by H. pales and Pachylobius picivorus observed in late August; probably result
of cooler weather, As expected, these weevils most active in burned over areas
or recently harvested stands. (Ark. For. Pest Rpt., Sept.).
WHITE-PINE WEEVIL (Pissodes strobi) - Damage continues severe in southern NEW
YORK, NEW HAMPSHIRE and MAINE. Heavy attack (over 20 percent current weeviling)
continued in west central PENNSYLVANIA counties in unprotected stands; in
northern tier. of counties, up to 90 percent attack reported in untreated
stands. Current weeviling high in northwestern NEW JERSEY, particularly in
planted trees and old fields. In southern WEST VIRGINIA (Mercer County) ,
species reported to have increased. (Northeast. For. Pest Rpt., Sept.).
SPRUCE BUDWORM (Choristoneura fumiferana) - MAINE - Assessment of data from pilot
test in Oxbow area uSing material Bacillus thuringiensis still in progress;
may not be available until fall or winter. General impression is that material
not effective incontrollingC. fumiferana on spruce and fir in area. On
regular spray project of approximately 500,000 acres, control rated as excellent
on pre- and post-spray larval counts. In areas outside spray area, reduction
of 35 percent from early to late larval populations occurred. Based on intensive
egg mass survey now in progress over entire area, following general observations
- 1149 -
can be made: Within spray area, only isolated heavy egg mass collections have
been made; outside and west of general spray area, egg mass numbers in 1963
declined in comparison with previous year's data, but more sampling may change
situation; in Oxbow area, where B. thuringiensis test conducted, current
defoliation of spruce and fir heavy, as well as egg mass numbers; isolated
area of infestation in Bancroft area, well south of general infestation, appears
to be declining. (Northeast. For. Pest Rpt., Sept.).
AN OLETHREUTID MOTH (Eucosma gloriola) - PENNSYLVANIA - Causing more wide spread
concern on white and Scotch pine plantings. Distribution probably statewide,
Moderate to heavy infestations noted during July in Butler, Adams, Bedford
and Susquehanna Counties. (Kelly, Stewart, Nichols; Pa. For. Pest Rpt.,
Aug. 14). In Mercer County (western area), 10 percent of pines in white pine
plantation attacked. Species relatively new to this area of State. NEW
JERSEY - Damage by insect tentatively determined as this species, found in
hybrid white pine in experimental plantation at Washington Crossing State Park.
(Northeast. For. Pest Rpt., Sept.).
SPRUCE NEEDLE MINER (Taniva albolineana) - CALIFORNIA - Locally heavy on blue
spruce in Susanville, Lassen County. Species subject to eradicative treatment.
(Cal. Coop. Rpt.).
ZIMMERMAN PINE MOTH (Dioryctria zimmermani) - WEST VIRGINIA - Found in Scotch
pine plantations in Boone and Mercer Counties. This believed to be first record
for State, although recorded for some of surrounding States. (Northeast. For.
Pest Rpt., Sept.).
LARCH CASEBEARER (Coleophora laricella) - RHODE ISLAND - Damage very minor this
year in several larch plantations under observation. (Northeast. For. Pest
Rpt., Sept.).
A PINE LOOPER (Lambdina athasaria pellucidaria) - MASSACHUSETTS - Adult
emergence from overwintering pupae occurred about mid-June on Cape Cod;
Oviposition shortly thereafter. Eggs and young larvae observed on old pitch
pine needles July 2. Infestation general throughout Barnstable County; heavy
defoliation expected in Dennis, Truro, Mashpee and Falmouth. Application of
Bacillus thuringiensis planned for early September if infestation persists;
presently appears to be declining due to natural causes. (Northeast. For. Pest
Rpt., Sept.).
TIP MOTHS - ARKANSAS - Activity generally spotty; damaging populations very
local. Scattered summer rains favored tree growth in mid and late summer,
thus trees tolerated attack better than in absence of good growth, (Ark. For.
Pest Rpt., Sept.).
BALSAM WOOLLY APHID (Chermes piceae) - NORTH CAROLINA - Caused additional
mortality to Fraser fir stands in Mt. Mitchell and Balsam Gap areas. Large
scale outbreaks discovered on Roan Mountain and Grandfather Mountain and in
Great Smoky National Park; located during survey by U. S. Forest Service.
(For. Pest Newsltr.).
A PINE LEAF APHID (Pineus pinifoliae) - MAINE - Continues serious on white pine
in eastern area. In northern Aroostook County, crooked-shaped pine branches,
characteristic of damage by this species, noted in area near Oxbow. NEW
HAMPSHIRE - Tips of white pine beginning to droop and die in nearly alli areas
where red spruce found in proximity to white pine. NEW YORK - In Hamilton
County, new growth on pine being killed; also reported as heavy on white pine
in northern Herkimer County. Heavy but local infestation reported in township
of Parishville. (Northeast. For. Pest Rpt., Sept.).
A PINE APHID (Essigella pini) - PENNSYLVANIA - Caused severe defoliation of all
except current year's growth on 60 acres of Scotch pine in Fayette County (Sept.
10); abundant on some Scotch pines in Indiana County, on all needles, but old
needles yellow and dropping (Sept. 14). (Udine).

A RED-PINE SCALE (Matsucoccus resinosae) - NEW JERSEY - Surveys continue in
northern part of State in area where eradication attempted. No further
infestations found. (Northeast. For. Pest Rpt., Sept.).
PINE SAWFLIES (Neodiprion spp.) - PENNSYLVANIA - N. lecontei lightly defoliated
red pine in Potter County. (Kane). Controls to be applied. (Pa. For. Pest
Rpt., Aug. 14). N. lecontei heavy on few Mugho pines at Tunkhannock, Wyoming
County. (Andreychik, Aug. 9). In Monroe County, virus common to N. sertifer
used to suppress outbreak. NEW JERSEY - Populations of N. sertifer very low
in northern half of State where previous damage heavy. Moderately infested
plantation successfully treated with disease-causing virus of this pest.
N. pratti paradoxicus and N. pini-rigidae also rare this spring in southern area,
where both proved damaging in past as part of complex attacking pitch pine.
MARYLAND - Full-grown N. lecontei larvae found in Garrett County. WEST
VIRGINIA - Full-grown larvae of N. lecontei also found in Grant County. In
adjoining Hardy County, larvae full grown by mid-September 1962. VIRGINIA -
Adults and larvae of N. lecontei found August 6 in several young shortleaf pine
plantings (2-5 feet tall) on Clinch Ranger District, Jefferson National
Forest; some newly emerged larvae also found. Due to altitude and terrain,
only one late generation occurs in area. N. pratti pratti lighter this year
than in 1962. (Northeast. For. Pest Rpt., Sept.). ARKANSAS - Adult emergence
of N. taedae linearis will begin in late September and early October. Foresters
should watch for egg deposition in pine stands bordering areas defoliated past
spring; this will provide indication of possible spread of this pest. No
recent activity by N. lecontei noted. (Ark. For. Pest Rpt., Sept.). FLORIDA -
Surveys during August showed N. excitans outbreaks deteriorated to endemic
levels, with little or no tree mortality occurring in any area. (McCowan).
LARCH SAWFLY (Pristiphora erichsonii) - MAINE - In Washington County, where
defoliation recorded on 28 numbered trees on study plot, current defoliation
light; but somewhat heavier defoliation of larch noted in areas toward coast.
NEW YORK - Heavy defoliation of planted European larch on Tombannock Reservoir,
Rensselaer County, reported; in town of Greenwood, Steuben County, 50-60 acre
Japanese larch plantation heavily defoliated. (Northeast. For. Pest Rpt.,
Sept.). PENNSYLVANIA - Caused moderate to heavy defoliation of Japanese and
European larch in portions of Indiana, Lycoming and Clinton Counties. (Herman,
Miller, Walker; Pa. For. Pest Rpt., Aug. 14).
ELM LEAF BEETLE (Galerucella xanthomelaena) - CALIFORNIA - Larvae medium on elms
in Coalinga, Fresno County. (Cal. Coop. Rpt.). ARKANSAS - Populations. forced
to American elms in northwest area, as Chinese elms completely defoliated at
time of third-generation. emergence. Beetles will move into homes and
other buildings soon to hibernate; probably cause much concern because of large
numbers, (Ark, For. Pest Rpt., Sept.). ALABAMA - Continues to damage elms
in Lee, Macon, Autauga and Perry Counties; however, attack possibly not as
severe as previously reported. Heavy pupation noted about some elms in Perry
County. (Hairston et al.). OHIO - Moderate to heavy damage noted on 5 elms
in Miami County, west central. Trees half to three-quarters skeletonized;
only adults present. (Lyon).
LOCUST LEAF MINER (Xenochalepus dorsalis) - PENNSYLVANIA —- Caused 90 percent
defoliation of black locust over small area of Fayette County. (Kurtz).
Infestations in 1963 much reduced over severe defoliation of 1962, (Pa. For.
Pest Rpt., Aug. 14).
ELM BARK BEETLES - NORTH CAROLINA — Scolytus multistriatus collected from elm
in Forsyth County. This is a new county record. (Harmon, Farrier). ARKANSAS -
Dutch elm disease found in Benton, Boone, Fulton and Searcy Counties this
summer; this leaves only Baxter and Marion Counties, in northern tier, in which
disease has not been found. (Ark. For. Pest Rpt., Sept.).

ELM CALLIGRAPHA (Calligrapha scalaris) - SOUTH DAKOTA - Adults feeding on sap
draining from cankers on Chinese elm trees at Winner, Tripp County. Several
trees have died, but this can not be solely attributed to these beetles. (Hintz).
ASIATIC OAK WEEVIL (Cyrtepistomus castaneus) - OHIO - Light populations observed
in Adams and Scioto Counties. (Mowbray, Blair).
A LEAF-MINING WEEVIL (Odontopus calceatus*) - NEW JERSEY - Single adult found
August 1 on yellow-poplar in Warren County; several leaves mined by larvae
also found in same area. Significance of find not clear; area to be watched
closely. (Northeast. For. Pest Rpt., Sept.).
CARPENTERWORM (Prionoxystus robiniae) - NORTH DAKOTA - Larval damage reported
from over State. Hosts are poplar and ash in yards and shelterbelts. (N. D.
Ins. Sur.).
AMERICAN DAGGER MOTH (Acronicta americana) - NEVADA - Larvae light on silver
maple (Acer saccharinum) in Reno, Washoe County. (Gallaway).
CATALPA SPHINX (Ceratomia catalpae) -—- OHIO - Larval populations failed to
develop on catalpas throughout southwest this year. Complete defoliation of
catalpas occurred in area at this date in 1962. (Wells). MICHIGAN - Larvae
causing local damage in Ingham County. (Dowdy).
FALL WEBWORM (Hyphantria cunea) - PENNSYLVANIA - Black cherry apparently
main host in west central counties. Hatching date in area estimated as late
July, about one month later than in mountains of western Virginia, Infestations
apparently decreased in western Pennsylvania from levels of 1962. NEW JERSEY -
Infestations less abundant than in 1962. VIRGINIA - Adults and egg masses
first noted June 24 on hickories and basswood along Blue Ridge Parkway; newly
emerged larvae observed few days later. Larval webs encasing several leaves
noted by mid-July. Cool weather in Blue Ridge Mountains prolonged development
along Parkway. Early insect activity confined to hickories and basswood, but
webs later found on black cherry, sourwood, blackgum and black walnut.
Localized, heavy infestations along Blue Ridge Parkway sprayed in mid-July;
adequate control obtained. (Northeast. For. Pest Rpt., Sept.). ARKANSAS -
Infestations much heavier than usual across northwest part of State; large
areas of persimmon, walnut, hickory and pecan trees completely defoliated
this summer. (Ark. For. Pest Rpt., Sept.).
FALL CANKERWORM (Alsophila pometaria) - PENNSYLVANIA - Heavy populations destroyed
by late freezes that also killed hardwood foliage. Larvae that escaped freezing
probably died of starvation. NEW JERSEY - Common and abundant in west central
counties; some areas nearly completely defoliated. At Ring Manor State Park,
Passaic County, hundreds of large (18 to 24-inch d.b.h.) red and black oaks
died this year following heavy defoliation in 1962. WEST VIRGINIA - Rare, due
at least in part to late freezes that destroyed insects and foliage.
(Northeast. For. Pest Rpt., Sept.).
SPRING CANKERWORM (Paleacrita vernata) - MASSACHUSETTS - Controls applied to
11,325 acres of woodland south of Boston in May and June. NEW YORK - Infestations
appear to be declining in Rockland and Ulster Counties. PENNSYLVANIA - Light
infestations in northern and southeastern counties made generally lighter by late

spring freezing temperature; however, late developing infestation causing
moderate defoliation found in northern McKean County. A geometrid moth
(Operophtera bruceata) may be component of infestation. MARYLAND - Oaks heavily
defoliated in 1962 and 1963 in Bachmans Valley, Carroll County, reported being
attacked by buprestid beetles. WEST VIRGINIA - Only occasional larvae found;
rareness of species due at least in part to late freeze. (Northeast. For.
Pest Rpt., Sept.).
FOREST TENT CATERPILLAR (Malacosoma disstria) - MAINE - Defoliated poplar in
area south of Caribou, Aroostook County. PENNSYLVANIA - Only few caterpillars
observed, without defoliation, in Clarion, Clearfield and Mercer Counties,
western area. Frost in late May at least partly responsible for low
populations. NEW JERSEY - Investigation of heavily defoliated 100-acre area in
Salem County (southwest) showed approximately 35 percent of pupae parasitized.
Light infestation found on 2-acre oak stand in Hunterdon County, west central.
(Northeast. For. Pest Rpt., Sept.).
LINDEN LOOPER (Erannis tiliaria) - VERMONT - Comonly found associated with
gypsy moth (Porthetria dispar) in Bennington County. MASSACHUSETTS - General
infestations declining throughout State. As expected, heavy hatch occurred about
May 1, but disease and parasites quite effective in reducing larval populations.
NEW YORK —- Hardwoods being defoliated in Hamilton County from town of Long
Lake north to county line; noted as abundant in towns of Hope and Wells and
caused some annoyance to people using picnic areas on Lake Durant and Lewey
Lake. At Lake Eaton, campsite treated June 12 to prevent damage. Beech and
birch apparently suffer most from defoliation in Hamilton and northern Fulton
Counties. Light defoliation recorded in townships of Clifton, Colton, Fine
and Piercefield in Andirondack Mountains. Defoliation also noted in Osceola,
Highmarket, Montague and Worth in Jefferson and Lewis Counties. PENNSYLVANIA -
Heavy larval numbers nearly eliminated by late spring freeze. (Northeast.
For. Pest Rpt., Sept.).
VARIABLE OAK LEAF CATERPILLAR (Heterocampa manteo) - OKLAHOMA - Larvae
defoliating pin oaks in Stillwater area, Payne County (north central); also
feeding in Shawnee area, Pottawatomie County (central). (Okla. Coop. Sur.).
AN OAK LEAF ROLLER MOTH (Argyrotoxa semipurpurana) - PENNSYLVANIA - Heavy
populations, chiefly this species, expected to cause heavy defoliation, failed
to survive late spring freeze. NEW JERSEY - Defoliation to nearly 100 percent
found in north central area, where populations were common and abundant.
Other spring defoliators minor components: of populations. Refoliation has
masked damage of heavily defoliated trees. (Northeast. For. Pest Rpt., Sept.).
CHAIN-SPOTTED GEOMETER (Cingilia catenaria) - PENNSYLVANIA - Outbreak developed
Over approximately 50 acres in Monroe County; trees and shrubs completely
defoliated, including scrub oak, pin cherry, pitch pine, blueberries and

GYPSY MOTH (Porthetria dispar) - MAINE - Two adults captured in Northfield and
Single collections made from traps in Alexander and Plantation 14 E, D.,
Washington County. NEW HAMPSHIRE - Large number of egg parasites observed in
Red Hill section of Moultonboro; up to 5 parasitic flies per single egg mass.
VERMONT - Single collections made in Bakersfield, Enosburg and Montgomery,
Franklin County, and in Cambridge and Hyde Park, Lamoille County. NEW YORK -
Three traps yielded 9 males in Brownville, Jefferson County, south and
southwest of area treated last spring. At site 1.5 miles from treated area,
100 or more new egg masses found. In other areas outside of regulated area,
adults recovered from 7 traps in 3 towns in Franklin County and 15 traps in
2 towns in Hamilton County. In suppressive area of State, 291 traps in Orange
County, 57 traps in Rockland County and 148 traps in Westchester County attracted
1,027 adults. In Nassau County, 21 traps yielded 35 specimens and, in Sullivan
County, 38 traps attracted only 61 moths. Only 2 moths captured in suppressive

area in central New York; one each in Oneonta and Exeter townships, Otsego
County. Intensity of recoveries in southern area of State reveals serious
spread from generally infested areas to north and east. PENNSYLVANIA - Total
of 21 males recovered from 12 traps in Northampton, Monroe and Pike Counties;
egg clusters found at 3 of 5 sites in Northampton County. (PPC, East. Reg.,
Aug. Rpt.).
BROWN-TAIL MOTH (Nygmia phaeorrhoea) — NEW HAMPSHIRE - Four adults trapped at
Hooksett and 1,443 (1,356 males and 87 females) trapped at Loudon, Merrimack
County; winter webs clipped and destroyed at Hooksett site last spring. (PPC,
East. Reg., Aug. Rpt.).
GEOMETRID MOTHS - PENNSYLVANIA - Moderate numbers of Calocalpe undulata
causing moderate "flagging" on all black cherry over 100 acres in Union County.
(Miller; Pa. For. Pest Rpt., Aug. 14). C. undulata nearly absent on black
cherry in west central area, where sufficiently abundant in 1962 to cause
browning of hillsides. (Northeast. For. Pest Rpt., Sept.). VIRGINIA -
Phigalia titea caused heavy defoliation of hardwoods, mostly oaks, in Lee
Ranger District, George Washington National Forest, in 1962 and 1963. Peak
adult emergence in 1963 occurred March 23-26, and egg hatch on or very close to
April 3, Initially, only available food was green tissue of barely opened
buds of bushes and trees in understory, mainly blueberry and hickory; these
supported large number of small larvae, but great numbers died from failure to
reach food. Continued warm weather resulted in increased food supply and
P. titea larvae that survived on buds heavily defoliated stand. (Northeast.
For, Pest Rpt., Sept.).
NORWAY-MAPLE APHID (Periphyllus lyropictus) - OHIO - Moderate to heavy on maples
in Wayne, Stark and Summit Counties, northeast. Ranged 6-8 stem mothers and
30-40 nymphs per leaf on infested trees. Premature leaf drop prevalent in
most instances. (Neiswander, Lyon). ALABAMA - Ranged 25-100 per leaf on
ornamental maple in Marion and Perry Counties; causing 50 percent leaf drop.
(Hairston).

HACKBERRY-NIPPLE-GALL MAKER (Pachypsylla celtidismamma) - COLORADO - Numerous on
hackberry trees in Sedgwick County. (Hantsbarger).
AN OAK PIT SCALE (Asterolecanium minus) - PENNSYLVAINA - Caused dying of
chestnut oak over 1,000 acres in Cameron County; incidence of infestation
increasing. (Sevinsky). As reported in 1962 and 1963, this species again
on increase in State over many areas. Trees suffering severe dieback probably
will not survive, especially in view of dry weather. Trees should be salvaged
if possible before they become infested with wood borers. (Pa. For. Pest
Rpt., Aug. 14). In Lancaster and York Counties (southeast), thousands of
chestnut oaks died in 1963. This species believed to be major force in
complex of unfavorable events and agents resulting in widespread mortality.
(Northeast. For. Pest Rpt., Sept.).

INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES
BAGRADA BUG (Bagrada hilaris (Burm.))
Economic Importance: The bagrada bug is an important pest of crucifers and some
other crops in parts of Africa and Asia. It damages plants much the same way as
the harlequin bug (Murgantia histrionica (Hahn)) in North America and, from all
reports, appears to be just as destructive, if not more so, than this bug.
Bagrada bug has long been a pest of considerable importance in South Africa. It
is abundant and destructive during the dry months, but is not serious during the
wet months of the year. Damage has been estimated at hundreds of pounds sterling
each year. Bagrada bug is also regarded as a major pest of crucifers in West
Pakistan and India. B. picta F. and B. cruciferarum Kirk. are in synonymy with
Beehilaxds |) (Burm). 7) anit
Distribution: Recorded in Burma, Ceylon, Ethiopia, India, Iraq, Iran, Italy,
Kenya, Northern and Southern Rhodesia, Republic of South Africa, Sicily,
Tanganyika, West Pakistan, Uganda, United Arab Republic (Egypt) and U.S.S.R.
Hosts: Crucifers are the principal host plants, especially cabbage, turnip,
Yape, mustard, radish, cauliflower, etc. Plants of other families are also
injured, but to lesser extent. Some of these cultivated crops are beans, peas,
cowpeas, barley, oats, wheat, corn, sorghum, sugarcane, beet, carrot, foliage of
citrus, hollyhock, artichoke, lettuce, chrysanthemum, dahlia, coffee and cotton.
Among the native host plants are numerous crucifers and some grasses.
Life History and Habits: The biology as studied in Republic of South Africa is
as follows: Eggs are laid under lumps of soil; usually singly, but sometimes in
two's and three's. Hatching occurs in 8 to 14 days, depending on the temperature.
Nymphs molt five times in 50 to 81 days. They feed largely during daylight hours
when it is warm, hiding during the late afternoon and night between leaves of
plants, under lumps of soil and in rubbish of gardens and fields. Adults are
very active and migrate rapidly. Pairing takes place soon after the bug reaches
the adult stage and, shortly after copulation, the males die. The females
deposit eggs 7 to 10 days later and then die in 8 to 14 days. The number of
generations is variable and they overlap. Four or five is the usual number. The
total number of days for development ranged 58 to 81 days in the insectary at
Pretoria during 1914-1915 and 1916-1917. Weather conditions are important
factors influencing development. Wet and cold conditions retard development a
number of days.
In India, it was observed that this pest was greatly susceptible to changes in
weather conditions and its populations varied in accordance with the shelter
available in the crop. It protected itself from cold of winter or heat of
summer by remaining under thick foliage, weedy or lodged crop, within the loose
folds of leaves, crevices in soil or interspaces under clods, and it migrated
from the crop which did not provide it suitable shelter. When disturbed, the
pest ran in all directions and adults took flight only when greatly disturbed.
The suitable temperature range for feeding was 70° F. to 102° F., with 90° F,
being the optimum. It was rarely found feeding under exposed conditions. Peak
populations occur during the spring.
Pentatomidae, Hemiptera No. 157 of Series
CEIR 13(39) 9-27-63
eo AUZ AO)
Description: Coloration and markings variable, depending on the area. In South
Africa, the description is as follows: EGG - Broadly oval, less than one mm. in
length; creamy-white at first, turning orange to reddish. NYMPH - First stage
about one mm. in length. Head and thorax black. Abdomen deep orange with row
of black spots down center and another of black triangles around edge; black
spots become larger after each molt until only a few reddish spots remain on
abdomen. ADULT - Small, depressed, 4-7 mm. (0.16-0.28 inches) in length, male
only about two-thirds as large as female. Triangular in general outline.
General color black, with numerous symmetrically arranged orange and yellow
streaks and spots on both dorsal and ventral surfaces; ventral surface nearly all
yellow in most specimens. (Prepared in Survey and Detection Operations, in
cooperation with other ARS agencies).

WEATHER BUREAU 30-DAY OUTLOOK
OCTOBER 1963
The Weather Bureau's 30-day outlook for October calls for temperatures to average
below seasonal normals in states bordering the Atlantic, the Gulf of Mexico, and
the Appalachians. Above normal averages are predicted for the remainder of the
nation except for near normal in the eastern Lakes and Ohio Valley. Precipitation
is expected to exceed normal over New England, the South Atlantic States, and the
Pacific Northwest. Near normal amounts are indicated for the Middle Atlantic,
West Gulf, and Southwest border states. In the remainder of the country subnormal
rainfall is in prospect.
Weather forecast given here is based on the official 30-day ''Resume and Outlook"
published twice a month by the Weather Bureau. You can subscribe through the
Superintendent of Documents, Washington, D.C, 20250. Price $4.80 a year, $2.40
a half year.
WEATHER OF THE WEEK ENDING SEPTEMBER 30
Maritime polar air pushed into the Pacific Northwest at the beginning of the week.
It brought light rain to Washington, and, as it moved eastward, to Idaho, Montana,
and the northern Great Plains. By Tuesday the front stretched from the Red River
Valley of the North to the Oklahoma Panhandle. Light rains, generally less than
an inch, fell over the northern and central Great Plains. A stationary front,
draped across Florida, dumped drenching rains throughout most of the week over
the entire Peninsula.
A huge mound of high pressure dominated the weather over the eastern half of the
Nation. Afternoon temperatures ranged generally from the 50's and 60's over the
North Central and Northeast to the upper 70's and lower 80's along the Gulf and
lower Atlantic coasts. Subfreezing temperatures occurred on several mornings over
most of New England and New York, and the higher elevations of Pennsylvania,
Virginia, and West Virginia, and some of the mountain areas of North Carolina.
Thursday morning this high pressure area united with one which lay over the Great
Basin. The front which had separated them was pushed aloft and high pressure and
fair weather prevailed from the Great Basin to the Atlantic Ocean.
While the middle and eastern portions of the country were enjoying comfortable
temperatures characteristic of the early fall season, easterly winds over the Far
Southwest overcame the usual sea breezes and carried the 100° heat from the
deserts to the coast of southern California. This upset the familiar diurnal
temperature regime. The Los Angeles Weather Bureau Office registered 107° on
Wednesday and on Thursday the mercury at Los Angeles Airport rose to 110°. A
record-breaking 111° occurred at San Diego, and El Toro, the hottest place in
southern California, registered 113°. Afternoon temperatures at Los Angeles
exceeded 100° on every afternoon for 5 days beginning Wednesday.
Temperatures averaged above normal north and west of a line from El Paso, Texas,
to Chicago, Illinois, and below normal south and east of that line. The largest
negative departures were over northeastern New York and northwestern Vermont.
The largest positive departures were in .the Los Angeles vicinity where temperatures
averaged 16° above normal due to 5 consecutive days with afternoon temperatures
above 100°.
Light rains fell over much of Washington and nearby areas in Idaho and Montana.
Very little rain fell elsewhere west of 100° longitude. Generous rains, generally
exceeding 1 inch, fell over the area south and east of a line from Mobile, Alabama,
to Albany, New York, and extending on into New England. Some localities received
several inches. Precipitation in some spots in Florida exceeded 8 inches. Some
snow fell in extreme northern portion of New England on Monday, September 23.

FOREST, ORNAMENTAL AND SHADE TREE INSECTS
SOUTHERN PINE BEETLE (Dendroctonus frontalis) - ALABAMA - Activity continues
centered in eastern part of State. During 1963, activity remained at
relatively low level. In previous years, epidemic populations occurred during
late summer and early fall months. GEORGIA - Beetle activity continues at
reduced level on Chattooga and Tallulah Districts of Chattahoochee National
Forest. Estimated 1,600 infested trees found by aerial surveys during latter
part of July. Georgia Forestry Commission reports beetle now endemic in all
counties included in original control project. Approximately 814,000 trees
removed and treated since March 1962, Total number of treated spots approxi-
mately 18,400. Industry removed additional large number of infested trees
not included in above report. MISSISSIPPI - Beetle activity increased slightly
on Homochitto National Forest, but remains at relatively low level. Aerial
evaluation survey in July showed 1.5 infested trees per 1,000 trees, compared
0.4 for similar survey in April. SOUTH CAROLINA - Endemic populations in
Piedmont declined. Cooperative aerial and ground surveys during June and July
indicate approximately 26,000 infested trees, compared with 95,000 during June
1962. Suppressive programs on National Forest lands continue on Tyger, Enoree
and General Pickens Districts on Sumter National Forest. Activity increased
on Francis Marion National Forest, where 17,000 trees currently infested.
Although center of outbreak was on Witherbee District and Santee Experimental
Forest, recent detection surveys indicate spread to adjacent Santee and Wambaw
Districts. Most activity on wet sites, with 2-3 inches of water on ground.
Suppressive programs underway over entire forest. (Southeast. For. Pest Rpt.,
Aug.).
BLACK TURPENTINE BEETLE (Dendroctonus terebrans) - Populations in north and
central ALABAMA and GEORGIA generally at low level; however, localized
infestations reported. Activity on increase in southern parts of ARKANSAS,
Kisatchie National Forest, LOUISIANA, and Homochitto National Forest, MISSISSIPPI.
Active salvage and control operations being carried out in the National Forest
and by Arkansas State Forestry Commission. D. terebrans frequently associated
with D. frontalis (southern pine beetle) as secondary invader on Francis
Marion National Forest, SOUTH CAROLINA. In addition, D. terebrans infesting

on trees injured by logging or lightning. (Southeast. For. Pest Rpt., Aug.).
- 1183 -
ENGRAVER BEETLES (Ips spp.) - Activity increased in some areas in south ALABAMA
and south GEORGIA because of drought conditions. Ample rainfall during June
and July, however, reduced attacks. In LOUISIANA, activity increased in
Bienville, East Feliciana, East Baton Rouge and St. Helena Parishes, and the
Catahoula Ranger District, Kisatchie National Forest. I. avulsus was primary
causal agent. In MISSISSIPPI, Ips spp. activity also increased on Homochitte
and Bienville National Forests and in scattered areas over State. In SOUTH
CAROLINA, Ips spp. commonly found in trees struck by lightning on Francis
Marion National Forest and adjoining private lands in Berkeley and Charleston
Counties. On several occasions, I. avulsus brood emerged from lightning
strikes and attacked portions of crown and individual branches of adjacent
trees. (Southeast. For. Pest Rpt., Aug.).

STATE OF CALIFORNIA
DEPARTMENT OF AGRICULTURE
SACRAMENTO
June 28, 1963
€. 0) PY E-82-5
TO: All County Agricultural Commissioners
SUBJECT: Estimated Damage and Crop Loss Caused by Insect/Mite Pests - 1962
This report of estimated damage and dollar crop loss attributed to insect/mite
pests is a summarization of special reports submitted by the County Agricultural
Commissioners. Preparation of this information involves a great deal of work by
each County, and yet this data must of necessity be considered an estimate only,
as the final crop return information is not available at the required time of
preparation. The majority of the county reports were complete, giving estimated
crop value, percentage loss caused by insects and treatment costs on many of the
250 different kinds of commercial crops grown in the State on 131,000 farms.
Weather conditions during 1962 varied from normal patterns and many species of
insect/mites developed severe pest populations relatively rapidly.
Tallying of related pests comprising more than one species as a group was more
prevalent this year in field reports than has formerly been done, however, when
damage/loss is attributed to a single species it is so credited. The totals for
assessable yield loss and control costs do not always equal the estimated overall
total due to the overlapping of treatments for one or more species of insects
plus diseases or nutritional deficiency. For a more accurate representation of
state-wide losses, the maximum-minimum value is given rather than striking an
average.
Estimates in the pests of animals are partially incomplete due to lack of
centralized reporting, consequently they represent only a limited number of
counties. Forest pests are included through cooperation with the U.S. Forest
Service. In the case of Structural Pest Control reports estimated dollar costs
for individual structural pests are impossible to completely assess as treatment
for a combination of insect pests, rodents and wood rots is a general practice
in the industry. Termites are probably the most important from the economic
standpoint.
The attached table presents the breakdown of assigned damage/loss dollar value.

COOPERATIVE ECONOMIC INSECT REPORT
HIGHLIGHTS
The 1963 adult GRASSHOPPER survey in Wyoming indicates a total of 977,500 acres
of rangeland infested with moderate or above populations; this acreage 3 times
that of 1962. Moderate, widespread grasshopper populations causing damage to
pastures in Caldwell, Comal, Guadalupe and Hays Counties, Texas, and margins of
small grain fields in northwest Oklahoma. @e 1205).
Heavy, widespread populations of FALL ARMYWORM reported causing considerable
damage to pastures and small grains in McCulloch, Yoakum, Ochiltree, Brazos and
Burleson Counties, Texas, and some localized severe damage to pastures reported
in Pushmataha County, Oklahoma. (p. 1205). ALFALFA CATERPILLAR populations
caused severe damage to alfalfa in Virgin Valley, Clark County, Nevada; heaviest
in several years. ‘xtremely high populations of PEA APHID present in alfalfa
near Wooster, Wayne County, Ohio; many plants wilting and browning. (p. 1206).
THREE-CORNERED ALFALFA HOPPER continues to range from light to heavy on alfalfa
in areas of Arizona, and populations heavy in Brazos and Burleson Counties, Texas.
@ipnl20”).
WALNUT HUSK FLY heavy in peach fruit in San Jose, Santa Clara County, California;
first instance of peaches being infested in northern area of State. (p. 1209).
CITRUS RED MITE extended range in California and now nearly statewide and occurring
on many hosts other than citrus. (e210) ke
POTATO TUBERWORM continues active in northwest Ohio; adults reduced in blacklight
trap collections in Monroe County, Michigan, (p. 1210). CABBAGE LOOPER continues
a problem in areas of Arizona and New Mexico, and heavy infestations reported in
areas of Alabama. (p. 1211).
SPRUCE BUDWORM caused extensive but generally not serious damage to ponderosa pine
in northern Larimer County, Colorado. (p. 1213).
MOSQUITOES annoying in parts of Utah, New Mexico, Texas, Florida, North Carolina
and Delaware. In Lucas County, Ohio, mosquito populations lower and fewer
complaints encountered this year than in previous years. (ps 1216):
DETECTION
WALNUT HUSK FLY found for first time in Oregon (p. 1209); an ORB WEAVER SPIDER
(Argiope amoena) reported new to Hawaii (p. 1223); and an OECOPHORID MOTH

WEATHER OF THE WEEK ENDING OCTOBER 7
Unseasonably warm temperatures and abundant sunshine prevailed over most of the
Nation during the week ending October 7. Numerous stations scattered across the
country registered higher temperatures than had previously occurred in October
or so late in the season. Maximum temperature records were broken in Montana on
the 4th, in South Dakota on the Sth, from the Prairies eastward on the 6th and 7th,
and in Kansas on all three dates. A few stations registered lower early morning
temperatures than had previously occurred so early in the fall. Subfreezing
temperatures occurred in the higher valleys in the Rocky Mountains, in the
Columbus, Ohio, area, in the higher elevations of the Appalachian Mountains from
North Carolina northward to New England. Numerous places in New England registered
minimum temperatures of 32° or lower on one or more mornings.
High pressure dominated the weather over most of the Nation on Monday, September
30. Afternoon temperatures were mostly in the 50's and 60's over the Ohio River
Valley and northeastward. They exceeded 90° over the southwestern deserts, the
interior valleys of California, eastern Montana, and nearby portions of the
Dakotas. Elsewhere, maximums were mostly in the 70's and 80's. The central
Plains warmed to the 90's on Tuesday and Wednesday and 80° temperatures occurred
over portions of the Ohio River Valley. Fair weather continued over almost the
entire Nation,
A cold air mass pushed into the north-central portion of the Nation on Thursday.
It brought cooler temperatures to the Lake region and the upper Ohio River Valley
and light rains to Pennsylvania, New York, and eastward to the Atlantic. A
maritime polar air mass moved into the Far Northwest producing some light
thundershowers. High temperatures continued over the sandy Southwest and the
Rio Grande Valley.
The warm weather spread eastward and by the weekend numerous new maximum tempera-
tures were being set. Chicago, Illinois, and Milwaukee, Wisconsin, were among
the places that registered higher temperatures than had previously occurred in
October. Some of the locations which experienced warmer temperatures than had
previously occurred so late in the fall are Concordia, Kansas; South Bend,
Indiana; Detroit, Michigan; and La Crosse and Madison, Wisconsin. At the other
extreme, Hatteras, North Carolina, was among the few stations which registered
lower temperatures than had ever occurred so early in the fall.
Rainfall exceeded 6 inches at West Palm Beach and 1-1/2 inches at Key West,
Florida. Other parts of Florida received lighter amounts. Light rain fell along

HAWAIIAN INSECT NOTES
The following notes on Hawaii insect conditions were presented at the 693rd
meeting of the Hawaiian Entomological Society held on September 9, 1963,
AN AMPULICID WASP (Dolichurus stantoni) - A female was taken dragging its prey,
a cockroach (juvenile, probably Onychostylus notulatus;det. by A. B. Gurney),
by its antenna along bank of Aiea Heights trail. This was introduced from the
Philippines in 1917 and has spread through Oahu, Molokai, Kauai and Midway
Island. (C. M. Yoshimoto).
AN ANTHRIBID BEETLE (Araeocorynus cumingii) - Reared from Mucuna seed leis
purchased at the Pali look-out, Oahu, and brought in by local resident on
September 5, 1963. This beetle is endemic to the Philippines and has been
collected in Guam. Det. by Dr. J. L. Gressitt. (Mabel Chong).
A LACE BUG (Corythucha morrilli)- A moderate infestation of adults and nymphs
was noted on Wedelia trilobata at Kokohead, Oahu. This constitutes a new host
record for this tingid. (H. Nakao).
AN ORB WEAVER SPIDER (Argiope amoena) - The spider collected January 20, 1963,
and exhibited at the February meeting of the Hawaiian Entomological Society
(CEIR 13(10):186) has been determined as this species by Dr. W. J. Gertsch.
The species is known from China, Japan and New Guinea, but is new to Hawaii.
(F. Bianchi).
SOUTHERN GREEN STINK BUG (Nezara viridula var. smaragdula) is now present on
all major islands of Hawaii. In chronological order, latest reports as follows:
August 25 - one specimen collected at Tamura's Farm, Kaunakakai, Molokai
(J. R. Blalock); August 26 - one specimen found on passion-fruit farm of
Maui Farm Inc., Maui (S. Ajifu); August 27 - one adult and one egg mass found
2 blocks below Lanai Avenue, west end of Lanai City, Lanai, on chayote plant
(F. Burgos); (also, an unconfirmed report of an infestation in a plantation
field); August 28 - pair of adults and an egg cluster found at Fuke's residence,
Wailuku, Maui; August 29 - one dead adult found in a rain gauge at Village
6, Puunene, Maui (Reddicts, HSPA); 68 nymphs and 3 adults at Endo's, Paia, Maui,
from tomatoes, mustard cabbage, daikon and castor-bean, and 5 nymphs and adults
from eggplant at Lahainaluna High School, Lahaina (Kawamura). (C. J. Davis).

HIGHLIGHTS
FALL ARMYWORM larval activity increased on alfalfa in Graham County, Arizona, and
populations continue damaging to pastures and small grains in areas of Texas;
also damaging winter wheat in southwest Kansas. ALFALFA CATERPILLAR populations
heavy in alfalfa in areas of California, Arizona and Oklahoma. (p. 1237). PEA
APHID serious on alfalfa in areas of Ohio and increased noticeably in areas of
Wisconsin. SPOTTED ALFALFA APHID moderate to heavy on seedling alfalfa in Payne
and Garfield Counties, Oklahoma, but reproduction occurring and serious damage
could result; counts as high as 19 per single leaflet on seedling alfalfa in
central Kansas; increased noticeably in Wisconsin and now more widely distributed.
(ee 1238)
TARNISHED PLANT BUG populations light to heavy (6-15 per 10 sweeps) on alfalfa
in north central and northwest Oklahoma, and ALFALFA WEEVIL adults averaged 33
per 100 sweeps on same crop in areas of Wyoming. GRASSHOPPER adult surveys in
Idaho indicate 945,000 acres of rangeland and 88,600 acres of cropland presently
infested, despite control programs, (p. 1239). HESSIAN FLY infestation ranged
0-30 percent on early planted wheat in north central Kansas, (p. 1240).
TEXAS CITRUS MITE on Florida citrus higher than in September of prior years and
increasing; scattered, heavy infestations may be expected, PURPLE SCALE, GLOVER
SCALE and CHAFF SCALE. more widespread and infestations heavier than in recent
years, and YELLOW SCALE more abundant than in any prior year on record, with
further increase expected. (p. 1241).
BEET LEAFHOPPER apparently will be present in large numbers in Hagerman-Glenns
Ferry area of Idaho during the fall; host plants abundant and in vigorous condi-
tion. (p. 1242). Single PINK BOLLWORM male moth caught in sex trap October 4
in stub cotton in Maricopa County, Arizona; larval infestation heavy in many
cotton fields surveyed in Graham County. (p. 1243). VARIABLE OAK LEAF
CATERPILLAR locally severe in areas of Kansas, with severe defoliation noted.
(p. 1244).
DETECTION
A FLEAHOPPER (Spanogonicus albofasciatus) found for first time in Arkansas.
(p. 1243). New county records include EUROPEAN CORN BORER in Warren County,
Georgia (p. 1237); PINK BOLLWORM in Chicot County, Arkansas (p. 1243); ELM LEAF
BEETLE in Riley, Linn and Miami Counties, Kansas (p. 1245); and A WEEVIL
(Trachyphloeus bifoveolatus) in Skamania County, Washington (p. 1248).

WEATHER OF THE WEEK ENDING OCTOBER 14
Clear skies, abundant sunshine, warm days, cool nights, low humidity, and little
or no rain described the weather over most of the Nation for week ending October
14. Agriculturalists agreed that it was ideal weather for maturing of late crops
and harvest operations, but fine weather created problems in some areas. Some
fields became too dry for fall plowing and, especially in New York and New England,
the fields and woods became so dry that the fire hazard was serious. In fact,
numerous forest fires occurred in those areas. Afternoon temperatures on Monday
reached or exceeded 90° over the sandy Southwest, from Texas to Illinois, at
Detroit, Michigan, and over southern New England. Numerous stations in those
areas registered higher maximum temperatures than had previously occurred in
October. On Tuesday, the hot southwesterly flow gave way to an invasion of
cooler air which advanced over the northern half of the country. The temperature
at Detroit rose to 68° on Tuesday. It had reached 92° the previous afternoon.
Boston registered 90° on Monday, 72° on Tuesday. On Wednesday morning, temperatures
dropped into the 20's in some spots in New England, and at a few locations in
New York, Pennsylvania, and West Virginia. The cooling was especially noticeable
in New England. A few stations set new high temperature records on October 7 and
new low temperature records 3 days later. Chester, Massachusetts, registered
94° Monday afternoon and 23° on Thursday. Temperatures over the midsection of
the Nation continued hot. Fort Smith and Little Rock, Arkansas, registered 96°
on Thursday. This equaled Ft. Smith's previous record and set a new record at
Little Rock. The temperature at Kansas City, Missouri, climbed to 97° on Thursday.
It was the fourth occurrence of 90° temperatures in the first 10 days of October.
The long time average is only one 90° maximum in October at Kansas City.
About midweek, a low pressure area developed in the middle Plains. It moved
quickly to the Lake Region producing only patchy cloudiness and a few light
showers of little importance. Under bright skies, hot afternoon temperatures
continued over the Nation's middle. Maximum temperature readings of long standing

Quarterly Citrus Insect and Mite Outlook in Florida - October through December
This outlook is based on the assumption that weather beyond the period of the
current U.S. Weather Bureau's 30-day outlook will be normal. Therefore, the
forecasts given below cannot be viewed with the same degree of confidence as
those in the "Insect Situation in Florida" usually given twice each month.
Effects of the December 1962 freeze on tree condition and on pest populations are
diminishing but still evident. MITES were more abundant in cold-damaged groves
July through September. SCALES, MEALYBUGS and WHITEFLIES were less numerous in
in cold-damaged groves. Much of the increase reported for scales in State due to
buildup from abnormally low post-freeze levels to average pre-freeze levels in
these cold-damaged groves,
CITRUS RUST MITE will continue at high level in cold-injured groves. Trend will
be upward in most groves through November and will be more noticeable on fruit
than on leaves. TEXAS CITRUS MITE will remain above average and will gradually
increase until mid-December. Moderate to heavy infestations expected in 25
percent of groves; majority will be in cold-damaged groves, CITRUS RED MITE
populations will be near average. Upward trend in late October will cause
scattered infestations, mostly in cold-damaged groves. PURPLE SCALE, GLOVER
SCALE, CHAFF SCALE and.YELLOW SCALE will continue at above average level and will
gradually increase. Although majority of groves will have light infestations,
about 20 percent will develop heavy infestations of one or more of these scale
species. These are expected to be spotty infestations in the inner canopy of
trees. BLACK SCALE will remain above average with a decrease to low level
expected in November. Unaspis citri and Pinnaspis strachani will increase in
scattered groves now infested. GRASSHOPPERS and PLANT BUGS will be occasional
problems. (W. A. Simanton (Citrus Expt. Sta., Lake Alfred)).

During the period September 29 - October 5, a total of 430 infestations was
reported from TEXAS; 1 from NEW MEXICO; and 1 from OKLAHOMA. Specimens were
reported from 61 counties in Texas, 15 counties in New Mexico and one county in
Oklahoma. There were 3 cases of unknown origin in Texas. This reporting period
reflects the highest incidence of screw-worm found during any 7-day period this
calender year. The majority of cases in Texas are being found in and near the
overwintering area of a relatively mild winter. Slightly less than 118,000,000
flies were released during this period. Production continues to rise and it is
expected that within next few weeks, flies will again be released at the
138,000,000 level. (Anim. Dis. Erad. Div.).

HIGHLIGHTS
SPOTTED ALFALFA APHID locally heavy in Independence County, Arkansas, and
Oktibbeha County, Mississippi; continues to increase in Wisconsin and some damage
observed in southeast Illinois and Bedford County, Virginia; and generally low
populations observed in Kansas. (p. 1261). APPLE GRAIN APHID and ENGLISH GRAIN
APHID recorded on small grains in Payne and Logan Counties, Oklahoma; appearance
earlier than normal. (p. 1274). SOUTHWESTERN CORN BORER caused less lodging of
corn plants in Arkansas than for past 3 years, and damage by the borer found in
several Alabama counties. (p. 1262). ALFALFA WEEVIL adults continue active in
Utah and Colorado, and larvae continue to feed on alfalfa in Maryland with few
fields showing damage in latter State. (p. 1263). HESSIAN FLY damage to early
planted wheat variable in central and northern portions of south central Kansas,
and SORGHUM MIDGE caused light to heavy losses to late grain sorghum in Lea

recovered from several Arkansas counties and Louisiana parishes. Pink bollworm
infestation general in Eddy County, New Mexico, cotton; and heavy numbers of
larvae still being found in lint cleaners and in cotton fields in Graham County,
Arizona (pie 1267).
Larvae of a GALL MIDGE, probably Contarinia coloradensis, caused extensive damage
to ponderosa pines in area of Colorado, and INTRODUCED PINE SAWFLY caused

WEATHER BUREAU 30-DAY OUTLOOK
MID-OCTOBER TO MID-NOVEMBER 1963
The Weather Bureau's 30-day outlook for the period mid-October to mid-November
calls for temperatures to average above seasonal normals in the eastern two-thirds
of the Nation, except near normal along Gulf and South Atlantic coasts. In the
western third, below normal averages are predicted, except near normal in the
Pacific Northwest and along the west coast. Precipitation is expected to remain
subnormal in the eastern quarter of the country (except the extreme Southeast) ,
but substantial rains should replace dry weather over much of the central United
States. Precipitation in excess of normal is anticipated in most regions west of
the Continental Divide. In areas not specified, near normal amounts are in
prospect.
Weather forcast given here is based on the official 30-day "Resume and Outlook"
published twice a month by the Weather Bureau. You can subscribe through the
Superintendent of Documents, Washington, D.C. 20250. Price $4.80 a year, $2.40
a half year.
WEATHER OF THE WEEK ENDING OCTOBER 21
At the beginning of the week, a huge high pressure area spread over the East.
Another was centered over the central Rocky Mountains. Fair weather with typical
Indian summer continued over the East. Afternoon temperatures were generally in
the 70's and 80's with a few 90's scattered over the central and southern Great
Plains. Minimums were mostly in the 40’s and 50's, except in the higher elevations
of the northern Appalachians and at a few stations in New York and New England
where they dropped to freezing or near freezing. In the West, minimum temperatures
ranged from the 30's in the mountains and higher latitudes to the 50's along the
Mexican border. An upper level low pressure system, which separated the two high
pressure areas, produced some generous rains over the central Great Plains.
Wichita, Kansas, received 1.10 inches of rain on Wednesday. Des Moines, Iowa,
received 1.87 inches on Thursday, and Concordia, Kansas, received 1.11 inches on
Friday. Lesser amounts fell daily from Wednesday to Friday over a wide area which
extended from Kansas to Lake Michigan.
At midweek, an intense storm system - the remanents of a tropical storm from the
Pacific - provided rains over most of California and inland as far as the southern
Rocky Mountains. Needles, California, received 1.10 inches of rain on Friday and
1.18 inches fell at Phoenix, Arizona, on Saturday. Another storm moved into the
Far Northwest about midweek. It produced light rains over the Northwestern States.
When it reached the Great Plains, they had become loaded with moist tropical Gulf
air. Precipitation fell Sunday over a wide area extending from the Great Basin to
Wisconsin and from Montana to Oklahoma. Tulsa, Oklahoma, received 1.91 inches and
1.37 inches fell at Wichita, Kansas, on Sunday. No important rain fell during the
week east of a line from Port Arthur, Texas, to Cleveland, Ohio, except at
Hatteras, North Carolina, and vicinity, where more than 3 inches fell on Saturday
and Sunday in connection with hurricane Ginny which was remaining almost stationary
about 125 miles southeast of Hatteras. Drought continued over the eastern United
States. In some States, it was the 5th week of dry weather and the longest dry
spell of record. Numerous woods and forests were closed to the public because of
the extreme danger of forest fires. Stockwater supplies ran low and ponds and
wells dried in some areas. In some areas, where light rains fell, runoff was
insufficient to raise stream levels. With warm daytime temperatures, abundant
sunshine, and low humidity, evaporation increased, intensifying the drought and
the forest fire danger became more frightening. Precipitation totaled less than
an inch over most of the West. Some spots along the Canadian border received no
rain. Some spots in the southern Rockies received more than 1 inch. The total
for Phoenix, Airzona, was 1.43 inches.
Temperatures averaged below normal over two small areas. In the interior valleys
of California, temperatures averaged from 1° to 3° below (continued on page 1276)

INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES
INDIAN SUGARCANE LEAFHOPPER (Pyrilla perpusilla (Walker))1/
Economic Importance: This fulgorid planthopper is one of the most destructive
pests of sugarcane and corn in Pakistan and India, and is common in Afghanistan.
Adults and nymphs suck plant juices from
the underside of the leaves and retard
plant growth if not checked. The pest is
capable of reducing the sucrose content
of the juice of sugarcane by about 1.5 to
2 percent or even more. Honeydew is also
sometimes a problem. In addition, cattle
refuse to feed on sugarcane, corn and
sorghum damaged by this pest. In 1953-
1954, a scheme costing 1,071,000 rupees
was organized to control the pest in the
Peshawar Region of Pakistan. Seventy
thousand areas of sugarcane and fifty
thousand acres of corn were treated that
year, which resulted in a saving of
approximately 6 million rupees. Recently,
Fennah (4) made a study of the species of
the genus Pyrilla StA4l found in Ceylon
and India. He concluded that two
polytypic species are present: P.
perpusilla (Walker) , widespread in India
and now recognized as extending to Ceylon
and to Thailand, and P. aberrans (Kirby)
(strict sense), formerly regarded as
being confined to Ceylon, but now found
to occur also in south India. Fennah
described and named 10 geographical
subspecies of the former and 5 of the
latter. Included is P. perpusilla pusana
(Distant) which is represented by 3 color
Indian Sugarcane Leafhoppers forms, each predominant in the population
on Sugarcane Leaf at a particular period of the year.
Hosts: Sugarcane, wheat, barley, oats, sorghum, corn, Sudan grass and other
native and cultivated grasses.
Distribution: India, Pakistan, Afghanistan, Ceylon and east to Thailand.
Life History and Habits: Females lay up to 773 eggs. They are laid in clusters
on the host plants and are covered with whitish, fluffy material. Eggs hatch in
7-12 days during April-October and 20-41 days during November-March. There are
5 nymphal stages. The nymphal stage occupies 24-65 days during April-September
and 78-208 days during October-March. The pest has 3-4 broods a year; the last
two (when present) overlapping each other. Adults are most common during late
March. Eggs are laid on sprouting sugarcane in April. From May to December, all
stages of the pest are encountered, but from January to the latter part of March,
nymphs predominate. When sugarcane is harvested, the pests migrate to other
susceptible crops such as wheat, barley, oats and other grasses. When the small
grains are harvested, they migrate to sugarcane, corn and sorghum,
17 Also called sugarcane pyrilla No. 158 of Series
Homoptera : Fulgoroidea :Lophopidae CEIR 13(43) 10-25-63

Description: ADULT (P. perpusilla perpusilla(Wlk.)) - Body and legs ochraceous,
paler beneath than above; termina yellowish-white, semi-opaque, apical area and
outer claval margin speckled with minute black spots; wings pale hyaline; dorsal
ridge to cephalic process much less prominent in front of the central trasverse
ridge than behind it. Length (excl. tegm.) 9 mm. or three-eighths of an inch.

HIGHLIGHTS
PEA APHID causing severe injury to alfalfa in many southeast Ohio fields;
locally heavy in areas of Maryland, Delaware and Wisconsin, and building up in
Dona Ana County, New Mexico. Large SPOTTED ALFALFA APHID populations depositing
heavy amounts of honeydew on alfalfa in Wagoner, Muskogee and Sequoyah Counties,
Oklahoma. Occasional specimens of GREENBUG found on wheat in Bixby area of
Oklahoma (first record of season), but none found on wheat in Texas Panhandle.

of alfalfa and mixed clover-alfalfa in Wisconsin. (ye 1291)
CITRUS FLAT MITE present on most citrus in Yuma County, Arizona, and causing
damage in some areas. On Florida citrus, CITRUS RUST MITE populations increased
into high range and TEXAS CITRUS MITE continues to be more abundant than in prior
years. In addition, PURPLE SCALE, GLOVER SCALE, CHAFF SCALE and YELLOW SCALE
continue to be above average in abundance; and WHITEFLIES (larvae) increased
further and are the highest in 12 years of record, but a decrease is expected in
November. (p. 1293).

WEATHER OF THE WEEK ENDING OCTOBER 28
Dry weather continued over most of the Nation from the Rocky Mountains eastward
to the Atlantic coast. The important exceptions included the lower Rio Grande
Valley, a few small scattered areas in the northern and central Great Plains,
and a narrow strip along the coast of the Carolinas. Parts of Kansas remained
"extremely dry" as was much of Oklahoma. Most of Illinois received no rain of
consequence. The drought continued in Indiana and was in the sixth week in Ohio.
Columbus, Ohio, received no more than very light sprinkles in 45 days. In
Pennsylvania, the drought was in the 4th week. Wells and streams were low. Some
stations in New Jersey received from light sprinkles to 0.40 inch of rain on the
28th. It was the first rain since October 4. The situation was equally severe
in the South. Louisiana had received almost no rain since September 29. The
drought persisted in Mississippi, Alabama and Georgia, and was in the 4th week
in Tennessee. The drought was in the third week in Kentucky and continued in the
Carolinas (except along the coast), in Virginia, and northern Maryland. In much
of the drought area, the danger of forest and brush fires was extremely high.
More than 100 woodland fires occurred in New England during the week.
Hurricane Ginny, centered at the beginning of the week about 115 miles southeast
of Cape Hatteras, North Carolina, drifted southward to a position off the coast
of north central Florida. By midweek, she began moving northwestward producing
rains along the Carolina coast. Hurricane warnings were displayed Friday from
Charleston, South Carolina, to Cape Fear, North Carolina, and residents were
warned to prepare for hurricane winds and high tides. The damage, however, was
confined mostly to beach erosion in North Carolina. By the end of the week,
Ginny had brought heavy rains and strong winds to the Carolina coast and had
moved eastward toward Bermuda.
The Pacific Northwest received substantial rains from three storms during the
week. The first front produced heavy rains, 2 to 3 inches or more, and gales
along the Washington coast. By midweek, the front had crossed the Rocky
Mountains and trailed from Lake Winnipeg across the Dakotas, the Nebraska
Panhandle, Colorado, and southwestward to San Diego, California, and a new giant
of a storm brought more rains to the Northwest. This second front moved quickly
across the Great Plains and by Monday morning, October 28, stretched from near
Boston, Massachusetts, to Midland, Texas. It produced some light sprinkles over
the northern and central interior but was followed by the first freezing temper-
atures of the season over the northern and central Great Plains. In many areas,
this was the latest that the first freezing temperatures of the fall season had
occurred. The third storm was approaching the Pacific Northwest at the end of
the week. Widespread rains fell over the northern Great Plains on Monday,
September 21. Scattered rains, not heavy (except locally) but significant,
dampened Texas and Oklahoma during the first half of the week. More scattered
rains occurred over the north central areas, but the totals failed to relieve
the dry situation which has resulted from the scanty rains over the past several
weeks,
Temperatures for the week averaged below normal over Oregon, northern California,
and southwestern Washington; also in the vicinity of Bakersfield, California.
They averaged above normal over most of the rest of the Nation. Most of the
Country from Oklahoma City, Oklahoma, northward to the Canadian Border, eastward
to Tennessee, and northeastward to New England averaged more than 10° above
normal, Numerous stations over the northern Great Plains and Lake region
averaged 15° above normal. Some of the areas where no rain fell during the week
include southern California, most of Arizona, New Mexico (except the north central),
the Texas High Plains, western Kansas, eastern Colorado, southwestern Nebraska,
Louisiana, the eastern half of Arkansas, southeastern Missouri, east central
Indiana, most of Ohio, Tennessee, western North Carolina, western South Carolina,
Mississippi, Alabama, Georgia (except the coast), western Florida Peninsula, and
much of the area from Richmond, Virginia, northeastward to New England. (Summary

Ohio Spittlebug Survey - 1963
Results of annual fall survey of meadow spittlebug (Philaenus spumarius) adult
populations presented on map below. On the basis of the survey just completed,
spittlebug populations are above those of 1962. There will undoubtedly be damage
in a band across the central portion of the State next spring, whereas, populations
will remain low and noneconomic in much of northern and southeastern areas. Some
fields in low areas may benefit from spraying next spring. Conversely, there will
undoubtedly be fields in moderate and high areas that will have relatively low
numbers, as spittlebug populations are often quite variable from field to field.
If nymphs can be easily found while quite small, they are likely to be abundant
enough to cause damage. On the average, one adult per sweep in early September
will produce one nymph per stem the following spring. Control measures will pay
dividends where nymphal populations are at or above one per stem. (Treece,
Lyon, Holdsworth). ae aa

killed as single trees and groups, with infestation increasing. (A, Campbell,
USFS) .
SOUTHERN PINE BEETLE (Dendroctonus frontalis) - VIRGINIA - Fall coloration of
hardwoods caused cessation of aerial surveys for damage, probably until mid-
December. New outbreak of what is probably this species, first reported by
district personnel and certified by aerial observation, appears concentrated in
loblolly pine in northern Brunswick, southeast Lunenburg and central Dinwiddie
Counties. Limited reconnaisance surveys into southern Mecklenburg, Brunswick
and Greensville Counties showed evidence of limited activity. Spots in infested
zones ranged 0.25-0.50 acre in size. Resurvey of all areas of past activity in
early September showed scattered but reduced activity; about 50 percent of spots
being extensions of old infestations not salvaged. Recent aerial survey of
Eastern Shore showed no alarming increases in activity. In Farmville area,
emergence of major adult brood reported underway in mid-September. Active
throughout Waverly district, being most active in Brunswick, Dinwiddie and
Greensville Counties. Continued activity evidenced by kill of loblolly and
shortleaf pines in small patches in Chesterfield, Powhatan, Goochland and King
William Counties; still active in Fluvanna County in shortleaf pine and continued
activity evident in Amelia, Charlotte, Cumberland, Buckingham, Mecklenburg and
Prince Edward Counties; 5 new infestations noted in Accomack and Northampton

with prolonged drought conditions probably contributing factor. (Okla. Coop.
Sur.). VIRGINIA - Large numbers now found in competition with Dendroctonus
frontalis where infestations of latter species high last year. Increasing numbers
in competition with D. frontalis portends a decline in population of latter
species. Engraver beetles killed single Virginia pine in Roanoke County and
infested 9-10 shortleaf pines in tract in Scott County; I. avulsus killing group
of natural 3 to 4-year-old loblolly pines in Westmoreland County. (Va. For.

The Alfalfa Weevil in the Eastern United States
The alfalfa weevil, Hypera postica (Gyllenhal), has been known in the United
States since 1904. In that year specimens were identified from Utah. It was not
until 1952 that the weevil was reported in this country east of Nebraska. It had
been the belief of entomologists that the weevil would not become established in
the eastern part of the United States because of the difference in climatic
conditions from those in its western habitat. However, in 1952, alfalfa weevil
specimens were identified from Maryland. Later in the same year specimens were
taken in Delaware, New Jersey, Pennsylvania and Virginia. In the succeeding
years, spread of the weevil was rapid in the south and east with infestations
being reported from Arkansas, Mississippi, and New Hampshire in 1963. In the
Eastern United States, the weevil has now been found in 20 states east of the
Mississippi River and in Arkansas west of the river. During the same period,
only three new states, Kansas, North Dakota, and Washington, were reported in the
West making a total of 15 states infested in that section of the Nation. The
accompanying map shows the present distribution of the insect in the United
States.
In order to determine the impact the weevil has had on alfalfa production in the
East and South, a questionaire was submitted to entomologists in each of the
infested States in these areas. The following table is based on the information
received, combined with existing U.S. Department of Agriculture records. No
attempt was made to summarize the material, since it is believed the reader will
obtain a much better picture of the problem and related costs if he makes a
critical study of the table,
A review of the material shows a striking example of the rapid spread of an
insect within a few years and how\it can affect the economy of one of our
important crops by reducing yield and quality as well as increasing the cost of
producing the crop.

WEATHER BUREAU 30-DAY OUTLOOK
NCVEMBER 1963
The Weather Bureau's 30-day outlook for November calls for temperatures to average
below seasonal normais in States along the Atlantic and Gulf coasts and in the
Appalachian region. Above normal averages are predicted in the western Great
Lakes, and also in the western half of the Nation except for near normal in
Pacific and southern border States. In areas not specified, about normal temper-
atures are indicated. Precipitation is expected to remain deficient in the
eastern half of the Nation, except for near normal rainfali along the Atlantic
and Gulf coasts. Subnormal precipitation is also anticipated over the northern
Rockies and in the far Southwest. isewhere in the western half of the country
near normal amounts are indicated except above normal along the central and
northern Pacific coast.
Weather forecast given here is based on the official 30-day "Resume and Outlook"
published twice a month by the Weather Bureau. You can subscribe through the
Superintendent of Documents, Washington, D.C. 20250. Price $4.80 a year, $2.40
a half year.
WEATHER OF THE WEEK ENDING NOVEMBER 4
At the beginning of the week, a mound of polar continental air lay over the
Country's midsection and was pushing a cold front southeastward toward the Gulf
and Atlantic coasts. It brought light sprinkles to the lower Missouri and Ohio
River Valleys and subfreezing temperatures throughout most of the southeast. The
cold air, flowing across the warm waters of the Great Lakes, triggered numerous
thunderstorms and a few tornadoes and waterspouts. On Monday, October 28, a
storm approached the northwestern coast of Washington. It brought rain to the
coastal locations and snow to the higher elevations. As the cold front moved
inland, it brought snow to the northern and central Rocky Mountains and a few
flurries to the nerthern Great Plains. Leadville, Colorado, received 7 inches and
Lander, Wyoming, received 2 inches. A few light flurries occurred as far south
as Madison, Wiscensin. As the storm crossed the Great Plains and moved southeast-
ward, it produced rains over most of the Nation from the Great Plains eastward to
the Atlantic coast. Snowfall in Pennsylvania ranged from light flurries up to
6 inches, Heavier snowfall occurred in New England. Greenville, Maine, received
15 inches. Some other locations in Maine received up to 9 inches of snow. The
cold front, as it pushed southeastward, dropped the temperatures to new lows for’
the season, Subfreezing temperatures occurred as far south as San Angelo, Texas,
and the coasts of Alabama and Georgia. The cold temperatures ended the growing
season for tender vegetables. The cold front passage was accompanied by widespread
light rains over most of the northeast quarter of the Nation on Thursday, from
Texas to the Great Lakes and eastward (except Florida) on Friday, and from
Michigan to North Carolina and northeastward on Saturday. The light rains did not
end the drought but reduced the danger of forest fires. Another storm approached
the Far Northwest on Friday. It brought more precipitation to Washington, Oregon,

CEREAL AND FORAGE INSECTS
SPOTTED ALFALFA APHID (Therioaphis maculata) - WASHINGTON - Surveys have been
negative this year. This is first time in several years, infestations have not
been found in southeastern part of State in early fall. (Harwood, Telford).
NEVADA - Averaged 1 per sweep in Moapa Valley alfalfa fields, Clark County.
(Zoller). NEW MEXICO - Generally light in Chaves and Eddy County alfalfa fields.
(N. M. Coop. Rpt.). OKLAHOMA - Large populations depositing moderate to heavy
amounts of honeydew on alfalfa in Garvin, Murray and Bryan Counties; counts up
to 1,250 per 10 sweeps. Moderate counts reported in Cotton County, with 350 per
10 sweeps noted in Tillman County, both in southwest. (Okla. Coop. Sur.).
KANSAS - Abundant in Pottawatomie and Shawnee Counties in Kaw River Valley since
recent rains. (Gates) . Counts ranged from less than one to 200 per sweep in
southeastern area. Some chemical controls have been applied in extreme southeast.
(Peters). SOUTH DAKOTA - Averaged 64 per 100 sweeps in southeast area alfalfa.
Gross morphology of species indicates that sexual form may be present, although
thorough examination of aphids has not been completed at this time. (Hintz).
WISCONSIN - Populations decreased; numbers in observation field at Brodhead
dropped to 300-500 per sweep October 29 and 200 per sweep October 31. Alates in

POTATO LEAFHOPPER (Empoasca fabae) - WISCONSIN - Averaged 1 nymph per sweep in
many alfalfa fields in southern area. Few adults present; nymphal counts run as
high as 8 per sweep. (Wis. Ins. Sur.).
THREE-CORNERED ALFALFA HOPPER (Spissistilus festinus) - OKLAHOMA - Counts per 10
sweeps in alfalfa ranged 1-5 in Garvin and 6-12 in Bryan Counties, south central.
(Okla. Coop. Sur.).
MEADOW SPITTLEBUG (Philaenus spumarius) - OHIO - Moderate adult numbers still
being found in west central area alfalfa in spite of cool temperatures. Adults
per sweep averaged 2.5 in Champaign County and 1 in Auglaize County in old
alfalfa fields. (Lyon).
A COCCID (Chortinaspis subchortina) - TEXAS - Heavy populations damaging St.
Augustine Iawns in Bell County. This is third record of species in State;
previously reported on St. Augustine grass in Hidalgo County and on seacoast
bluestem in Kenedy County. (Decker, McDaniel).
ALFALFA CATERPILLAR (Colias eurytheme) - WISCONSIN - Larvae continue common in
many alfalfa fields; average as high as 1 per’ sweep. Wis... Ins. Sur.)):
OKLAHOMA - Ranged 1-3 per 10 sweeps in alfalfa in Garvin, Murray and Bryan
Counties (south central) and Tillman County (southwest). (Okla. Coop. Sur.).
NEVADA - Numerous adults, but very few larvae and pupae, found in alfalfa in
Moapa Valley, Clark County. (Bechtel, Zoller).
SOUTHWESTERN CORN BORER (Zeadiatraea grandiosella) - ARKANSAS - Survey showed
percent of lodged corn, by district, as follows: Northwest (4 counties), 2.8;
north central (4 counties), 0.4; northeast (6 counties), 1.7; east central (7
counties), 3.1. State average was 2.2 percent compared with 12.3 for 1962. Lower
percent of lodged corn in 1963 is due, in part, to a smaller percentage of corn
planted in June and July than in 1962 and past years; another influencing factor,
especially north of Arkansas River, was low survival of overwintering larvae
resulting from abnormally cold weather during winter of 1962-1963. (Ark. Ins.
Sur.).
SUGARCANE BORER (Diatraea saccharalis) - TEXAS - Light to moderate on second-
growth grain sorghum in Brazoria County. (Teetes).
CORN EARWORM (Heliothis zea) - OKLAHOMA - Light, scattered populations remain
active in alfalfa in south central and southwest areas. (Okla. Coop. Sur.).
GARDEN WEBWORM (Loxostege similalis) - OKLAHOMA - Light numbers reported on
seedling alfalfa in Roger Mills County, west central. (Okla. Coop. Sur.).
NORTHERN CORN ROOTWORM (Diabrotica longicornis) - OHIO - Populations continue to
decrease; adults averaged 4 per 50 sweeps in a field of alfalfa in Shelby County,
west central. (Lyon).
WESTERN CORN ROOTWORM (Diabrotica virgifera) - SOUTH DAKOTA - Resistance tests
run at the Northern Grain Insect Research Laboratory by Dr. E, W. Hamilton showed
various degrees of resistance by this pest to the chlorinated hydrocarbon
insecticides in southeastern parts of the State. (Hintz).
SPOTTED CUCUMBER BEETLE (Diabrotica undecimpunctata howardi)- OKLAHOMA - Ranged
4-8 per 10 sweeps in Bryan County alfalfa, south central area. (Okla. Coop. Sur.).
A SPOTTED CUCUMBER BEETLE (Diabrotica undecimpunctata tenella) - NEW MEXICO -
Adults ranged 8-13 per 100 sweeps in Sandoval County alfalfa fields. (N. M.
Coop. Rpt.).
CEREAL LEAF BEETLE (Oulema melanopa) - MICHIGAN - Data collected to November 1
shows very high adult mortality in such products as baled hay, baled straw and
stored grain; however, very few live beetles have been recovered recently from
- 1312 -
each of these products when handled according to conventional farm methods, Hay
and straw from which these beetles were recovered were harvested in May of this
year from heavily infested fields near Galien, Berrien County. (Turner).
WIREWORMS - NORTH CAROLINA - Melanotus communis and Conoderus lividus collected
from 2 adjacent fields near Pantego, Beaufort County. These large fields in corn
this year; reported to have been heavily damaged by these pests despite use of
recommended controls. Field sifting of approximately 3 square yards of soil
produced 13 larvae. Soil dark and high in organic material. (Jones, Mount).
GRASSHOPPERS - OKLAHOMA - Spot checks in wheat field margins in panhandle counties
showed no damage; 2 per square yard highest count. (Okla. Coop. Sur.). NORTH
DAKOTA - Egg survey in north central and central districts covered only fields
showing economic adult infestations; results aligned closely with adult survey.
Highest egg counts found in alfalfa, sweetclover and soil bank fields. Develop-
ment ranged clear to segmented, but most in coagulated stage. Melanoplus
bivittatus, M. sanguinipes, M. packardii, M. femurrubrum and M. differentialis
dominant species. Parasitism and predation by bee flies and carabid beetles
ranged up to 27 percent; average 6 percent. About 4 percent of eggs not viable,
due to lack of moisture. (Brandvick). WISCONSIN - Grasshoppers, primarily
M. femurrubrum, decreased noticeably; females continue to develop eggs. (Wis.
Ins. Sur.). OHIO - Melanoplus femurrubrum and M. differentialis populations
decreasing rapidly throughout northwest, central and west central areas.
M. femurrubrum numbers very low in west central area; no M. differentialis adults
found. (Lyon).
HESSIAN FLY (Phytophaga destructor) - KANSAS - Infestation in southeast district
ranges 0-4 percent of wheat plants infested; less than 20 percent of fields
infested. In extreme southeast and east portions of this district, drought
conditions were such that wheat did not emerge in time to be infested. Dry
weather also was not favorable for fly emergence, (Peters). OHIO - Puparia
easily found between leaf sheath and stalks of volunteer wheat plants throughout
Marion, Morrow, Hardin, Auglaize, Shelby and Logan Counties in central and west
central areas. Few autumn planted wheat fields examined with negative results.
Many wheat plants not yet emerged because of drought conditions. (Lyon).
WHEAT STEM SAWFLY (Cephus cinctus) - OHIO - Infested wheat stems and stubble
easily found in sections of Auglaize County, west central area. (Brown, Noble).
WHEAT STEM MAGGOT (Meromyza americana) - KANSAS - An occasional infested wheat
plant noted in southeast area, (Peters).
FRUIT INSECTS
UNSPOTTED TENTIFORM LEAF MINER (Callisto geminatella) - OHIO - Heavy on unsprayed
apple orchard near Columbus, Franklin County; 60-75 percent of leaves mined on
some trees. (Forsyth, Lyon).
PEACH TREE BORER (Sanninoidea exitiosa) - MARYLAND - Light in apple trees at
Fairland, Montgomery County. (U. Md., Ent. Dept.).
APPLE GRAIN APHID (Rhopalosiphum fitchii) - OHIO - Nymphs and adults light to
moderate in unsprayed apple orchard near Columbus, Franklin County; averaged
25-30 per leaf. Many dormant eggs noted on twigs. Also found on adjacent
autumn-planted wheat fields. (Lyon).

HAWAIIAN INSECT NOTES
The following notes on Hawaii insect conditions were presented at the 694th meet-
ing of the Hawaiian Entomological Society held on October 14, 1963,
A MANTID (Orthodera sp.) - Two males and 3 females were caught during latter part
of September in Ewa Beach area; all found on castorbean (Ricinus communis).
Dr. J. W. Beardsley first reported this insect when one specimen was taken in a
light trap at Waipio in September 1962. Since its collection, one female laid 3
batches of eggs. This mantid is now probably established in the State. Determi-
nation by J. W. Beardsley. (James Kim).
A CLUBIONID SPIDER (Cheiracanthium diversum Koch) - Collected on Kaunakakai,
Molokai, and Kaumalapau, Lanai, on September 26 and 27, respectively. (W. C.
Mitchell). Collected at several localities on Molokai on September 25 and 26.
The bite of this spider has caused serious discomfort to humans on Oahu in several
recorded instances. (J. W. Beardsley). These are new island records.
SOUTHERN GREEN STINK BUG (Nezara viridula (L.)) - Survey conducted by W. C.
Mitchell, Harry Nakao and J. W. Beardsley on Molokai and Lanai; infestations
reported as follows: Molokai - Aug. 25; Tamura Farm, Kaunakakai, Molokai; con-
firmed. Sept. 26; again confirmed with collection of one male on tomatoes.
Sept. 18; Burrows Farm, Palaau (Apana 1), one adult collected by R. Burrows and
infestation confirmed Sept. 25 by finding numerous nymphs. Sept. 23; one adult
collected by J. Uraichi at Kualapuu; further investigation revealed widespread
infestation around California Packing Company housing. Sept. 24; single adult
alighted on C. Lloyd at Hoolehua; no specimens found in area. Lanai - Aug. 27;
found at Lanai City; confirmed on Sept. 27. Sept. 5; single female taken by
N. Oda at Kaumalapau. Sept. 27; infestation widespread in harbor area.
(W. C. Mitchell).
A MYMARID WASP (Patasson calendrae (Gahan)) - Six releases of this species made
on Oahu thus far; 4 between August 16 and 29 at the Kunia substation of the
Hawaiian Sugar Planters Association; one on August 18 at Makiki Station; and one
August 30 at the Wailua Agricultural Company. Last release consisted of 150
wasps; other 5 totaled 27 wasps. Establishment of P. calendrae in State uncer-
tain, but breeding program to be continued vigorously in hope of establishment
because recent observations in laboratory have shown that species will not only
parasitize eggs of the BILLBUGS, Sphenophorus cariosus and S. venatus vestitus,
in vitro, but it is equally effective on the eggs of NEW GUINEA SUGARCANE WEEVIL
(Rhabdoscelus obscurus (Boisd.)), the most important pest of sugarcane in Hawaii.
(F, Bianchi, C. E. Pemberton).
AN AGAONID WASP (Euprestina verticillata Waterston) - Numerous adults observed
October 7 about Chinese banyan trees at residence in Honolulu; caused annoyance
to household; trees sprayed. (H. Arnold, Jr., C. E. Pemberton).
AN ARMORED SCALE (Kuwanaspis sp.) - Collected on leaves of ornamental bamboo at
2 widely separated localities during latter part of 1962; at Hilo, Hawaii, on
October 3 by J. W. Beardsley and at Nanakuli, Oahu, on December 8 by E. Shiroma.
A number of species of Kuwanaspis which are confined to bamboos are known from
the Orient, and one species, K. pseudoleucaspis (Kuwana), has been established
in Hawaii for a number of years. The newly discovered species, which is new to
Hawaii, closely resembles K. takahashii Takagi from Japan, except that the latter
lacks the perivulvar pores found in the Hawaiian form. The newly discovered
Kuwanaspis in Hawaii may be one of several described by the late Professor R.
Takahashi from Taiwan, but pertinent literature or specimens for comparison are
not available locally. Identification to genus made by J. W. Beardsley.
(J. W. Beardsley).
- 1324 -
A VESPID WASP (Polistes exclamans exclamans Viereck) - Collected at several
places around Kaunakakai and at Paalau, Molokai, on September 25 and 26. This
is the first record outside of Oahu in Hawaii. (J. W. Beardsley).
A CICADELLID LEAFHOPPER (Scaphytopius loricatus (Van Duzee))-Collected in vicinity
of Kaunakakai, Molokai, on September 25 and 26; first record for Molokai. (J. W.
Beardsley).
A DELPHACID LEAFHOPPER (Sogatella kolophon (Kirkaldy)) - Collected at Lanai City,
Lanai, on September 27; first record for Lanai. (J. W. Beardsley).
A PSOCID (Ectopsocus maindroni Badonnel) - Found covering walls and cupboards of
residence at Kailua, Oahu, on October 5. This species not recorded previously
from Hawaii, although in early 1962, Dr. Mockford of Illinois sent specimens of
this species that had been intercepted at Honolulu on material originating in
Hong Kong. Species originally described from Arabia, and has since been reported
from the Congo, Malaya, Hong Kong and Taiwan. Species apparently has wide range
of habitats; it has been taken on vegetation, in drawers and closets of private
houses, in a breakfast cereal packet, in cavity of a wild fig, from a young fish
owl, and from quite deep inside the Batu Caves of Malaya. The infested house in
Honolulu was on a recently constructed estate, and there had been trouble with
mildew in this and neighboring houses, which also harbored the insects. Moldy
shoes in a closet were infested, and it seems likely that the infestation was
associated with the presence of mold. (W. B. Thornton).
A PARASITIC ENCYRTID (Exoristobia philippinensis Ashmead) - Reared from puparia
of Trichopoda pennipes F., a parasite of Nezara viridula (ie) “This is first
record of this hyperparasite attacking T. pennipes. A specimen of E. philippin-
ensis was taken in a light trap at Honolulu in June 1961, according to B. D. Burks
who made the determination. (C. J. Davis).
A PARASITIC TACHINA FLY (Trichopoda pennipes F.) - Adults observed October 9 at
the mauka side of Wahiawa (elev. 1,200 ft.). One adult Nezara viridula had 237
T. pennipes eggs on its body, (W. C. Mitchell). A number of shipments of this
stink bug parasite were sent from Gainesville, Florida, by Noel Krauss during
September and October for breeding and distribution throughout Hawaii for biolo-
gical control of N. viridula. (C. J. Davis).
A TARO LEAFHOPPER (Tarophagus proserpina Kirkaldy) - Found established on Molokai
on September 25 by Harry Nakoa and W. C. Mitchell at Halawa and Wailau Valleys.
(C.J. Davis):
A GIANT AFRICAN SNAIL (Achatina fulica Bowdich) - Reported from Kalaupapa settle-
ment on Molokai by Koah Pekelo on September 25. On October 7, a resident of
Manaloa turned over a living African snail (3 inches long) to Jack Blalock, thus
making the second locality record for Molokai. (C. J. Davis).
RASPBERRY CROWN BORER (Bembecia marginata (Harris)) - Liberations of this aegeriid
commenced at Kokee in September (total of 90 adults released) to control blackberry,
a serious weed pest of Kokee and similar habitats in Hawaii. B. marginata was
collected in Oregon by Noel Krauss. (C. J. Davis).

INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES
INDIAN COTTON JASSID (Empoasca devastans Distant)
Economic Importance: This cicadellid is a well known major pest of cotton, and the
most important representative of the genus Empoasca on the Indo-Pakistan sub-continent.
The pest came into prominence early in the 1900's when it was found attacking American
varieties of cotton newly introduced in the Punjab. Since then, it also has been
reported as being serious on okra, potato, tomato and pepper. The latter three were
severely damaged during 1957-58 in West Pakistan, principally in the southern regions
of the country. E. devastans sucks the sap from cotton leaves causing them to shed.
This results in a shedding of bolls by the plant and a reduction in the quality of lint
produced by bolls remaining on the plant. Susceptible varieties often suffer a 25
percent or greater loss.
Among other species of Empoasca, E. kerri var. motti Pruthi and E. punjabensis Pruthi
occur with E. devastans on cotton in the Punjab. Studies conducted during 1940-42
showed that populations of the latter were low in some localities early in the season,
but the percentage increased slowly and reached a high figure towards the end of the
season, and was more evident in the southwestern part of the Punjab than elsewhere.
Because of the seriousness of this pest on American varieties of cotton in the Punjab,
preventive and protective measures became essential. Research studies, which began in
1937, indicated that the hairiness of the leaf vein appeared to be the most important
factor in resistance, and the use of hairy varieties of cotton is recommended where
infestations are heavy. Tree cotton and its varieties are practically immune.
Distribution: Ceylon, India, Pakistan (both East Pakistan and West Pakistan), Thailand
(™orthern) and New Britain. Recent records (Ghauri, 1963) show that the distribution
of E. devastans extends further to the east than recorded formerly, and approaches that
of E, terraereginae Paoli, which is restricted to Queensland, Australia. The latter
species is also a Serious pest of cotton.
Hosts: Cotton, okra, potato, tomato, eggplant, pepper, kenaf hibiscus, linden hibiscus
(emajagua) , hollyhock, castorbean, sunflower, Hindu datura and cacao.
Distribution of Empoasca devastans Distant
Cicadellidae, Hemiptera No. 159 of Series
CEIR 13(45) 11-8-63
- 1326 -
Life History and Habits: The biology as studied in the Punjab is as follows: Full-
grown cotton leaves, 35-45 days old, are preferred for oviposition. Infestation begins
the latter part of June or early July, six weeks after planting, reaches a peak the
last half of August and practically disappears by the beginning of November. High
atmospheric humidity was found to be the chief factor favoring the increase. Eggs are
laid inside the leaf veins, usually in the spongy parenchymatous layer between the
vascular bundles and the epidermis and have an incubation period of about 4-11 days.
A female may lay up to 29 eggs. Nymphs molt 5 times. This stage requires from 7 days
in the fall to 21 days during the winter. Unmated adults of E. devastans lived for 90
days or longer, but paired adults did not survive beyond 5 weeks in Summer and 7 in
winter. A total of 11 generations a year have been observed, but adults are long-lived
and the oviposition period is extended; therefore, there is considerable overlapping
of broods.
Description: ADULT - Head, pronotum and scutellum pale ochraceous; vertex with two
black spots on apical margin; face with the lateral areas more or less distinctly pale
brownish; body beneath pale ochraceous;
legs and tegmina pale greenish-ochraceous,
the latter with a black spot near apex of
each claval area; vertex of head short,
concially rounded anteriorly, more than
half as long as breadth between eyes;
pronotum with three grayish-white spots
near anterior margin; scutellum spotted
with grayish-white; tegmina extending far
beyond abdominal apex. Length excluding
tegmina 3 mm. The above adult description
is the original by W. L. Distant (3). The
most noteworthy feature by which the adults
can be recognized in the field is the
presence of a prominent black spot on each
of the tegmina near apex of the claval area.
Seasonal changes in coloration are also
present. The summer form is yellowish-
green with antennae pale white, eyes a
mosaic of green and white, tegmina with
greenish tinge and legs pale green. The
winter form is reddish-brown with antennae
pale white, eyes dark violet, tegmina with
a brownish tinge and legs green. - In between
these two extremes, there may be many inter-
mediate forms depending upon the time of
year. Descriptions of the various nymphal
stages are given in Husain (5). (Prepared
in Survey and Detection Operations in
cooperation with other ARS agencies).

WEATHER OF THE WEEK ENDING NOVEMBER 8
Several areas received more than an inch of precipitation during the past week.
The Washington and Oregon coasts received from 3-5 inches. Amounts tapered to
2-3 irches west of the Cascades and lesser amounts east of the mountains. Snow
accumulations in the high elevations of the Cascade and Olympic Mountains were
about the heaviest of record for so early in the season. Depths ranged from
6-10 inches at 3,000 feet, 24-30 inches at 4,000 feet and 50-60 inches at higher
elevations. Coastal areas of northern California received 2-4 inches of rain.
Snow fell in northern California above 4,500 feet. Wind gusts accompanying the
rains reached 60 m.p.h. along the coast. A frontal passage accompanied by
strong, gusty winds produced rain and showers in Arizona. Snow fell in Arizona
above 6,000 feet; accumulation reached several inches,
Southeast Texas received a few heavy showers early in the week. Thundershowers
dumped an inch or more over south central Texas on Friday. Some areas along the
middle and upper coast received 3-4 inches. Heavy rains fell along the coast
of Louisiana. Morgan City received 7.74 inches. The amounts tapered inland
to less than 0.20 inch. Much of Florida received over an inch of rain.
Scattered areas in central Florida received more than 3 inches.
Generous rains fell along the middle and northern Atlantic coast. Amounts
ranged generally from 4-5 inches in North Carolina, from 2-4 inches in Virginia,
Maryland and Delaware, from 2-4 inches or more in Pennsylvania, from 24-4
inches on Long Island and in the lower Hudson River Valley, 2-34 inches in
central New York, from 34 inches in southern New Jersey to 4 inches over the
north, and up to near or above 7 inches at a few locations in New England. The
generous rains relieved the drought and reduced the forest fire hazard.
Dry weather continued, however, over parts of the northern and central Great
Plains where many stations received no rain or only piddling amounts.
Temperatures averaged above normal over most of the Nation. Departures ranged
from +6° to +10° over the western Great Plains. Temperatures averaged slightly
below normal over the interior valley of California, on the western slope of
the southern Appalachians, and over southern Georgia.
Widespread cloudiness prevailed over the eastern half of the Nation on November
4 and 5. The storm deepened and, by Wednesday, was producing heavy rainfall over
the middle and northern Atlantic States. Another storm in the northwest
intensified, moved inland and produced rain over the Pacific States and the
Great Basin and snow in the higher elevations as far south as Arizona and New
Mexico. Snow also fell over the western Great Plains.
Frontal activity brought weekend rains to Texas, parts of Iowa and Minnesota,
A storm over the western portion of the Gulf of Mexico produced thundershowers
along the middle and upper coast of Texas and over southern Louisiana. At the
end of the week rain was falling over portions of Florida and a storm centered
north of Lake Superior was producing rains and a few snow flurries over areas
near the Great Lakes and along the St. Lawrence River. (Summary supplied by
U.S. Weather Bureau.)

Citrus Insect Situation in Florida - End of October - CITRUS RUST MITE
(Phyllocoptruta oleivora) infested 68 percent of groves (norm 69 percent); 55
percent economic (norm 42 percent). Population above average and in high range
and will continue high in most districts through November, especially in cold-
damaged groves. Infestations presently similar on leaves and fruit, but will
increase on fruit. Highest districts Gainesville, Brooksville, Bartow, west
coast and Orlando. CITRUS RED MITE (Panonychus citri) infested 51 percent of
groves (norm 46 percent); 17 percent economic (norm 21 percent). Population at
moderate level, normal for this time of year. Highest districts west coast,
Brooksville and Orlando. TEXAS CITRUS MITE (Eutetranychus banksi) infested 51
percent of groves (norm 24 percent); 19 percent economic (norm 7 percent). More
abundant than in any other October. Highest districts Brooksville, west coast,
ridge and Bartow. Both citrus red mite and Texas citrus mite presently at similar
level. Both may occur in same grove, but usually only one builds to heavy
infestations in same period. Because of the habits, injury and control measures
are Similar. The combined population should be taken into account. Thus, about
38 percent of groves may be expected to have moderate to heavy infestations of
these two species in November. PURPLE SCALE (Lepidosaphes beckii) infested 80
percent of groves (norm 63 percent); 18 percent economic (norm 4 percent).

YELLOW SCALE (Aonidiella citrina), infested 36 percent of groves (norm 13 percent) ;
- 1332 -
7 percent economic (norm 1 percent). All the above scale species continue above
normal abundance. Little change expected. Most infestations light to moderate,
but scattered groves in warmer areas will have injurious numbers. BLACK SCALE
(Saissetia oleae) infested 38 percent of groves (norm 34 percent); 13 percent
economic (norm 10 percent). Decrease to normal low level expected. WHITEFLIES
infested 77 percent of groves (norm 63 percent); 27 percent economic (norm 13
percent). Population in high range and above that of any prior October on record.
Heavy infestations will decrease but light infestations in cold-damaged groves
will become heavier, thereby keeping statewide population high. (W. A. Simanton
(Citrus Expt. Sta., Lake Alfred)).

ERIOPHYID MITES FOUND ON FLORIDA CITRUS
bes NG Denmark1/
Introduction: Three eriophyid mites occur on citrus in Florida. The citrus rust
mite (Phyllocoptruta oleivora (Ashmead)) was described from Florida in 1878. The
citrus bud mite (Aceria sheldoni (Ewing)) was first found in Florida by
H. H, Attiah in 1959 on sweet orange in South Miami. A pink citrus rust mite
(Aculus pelekassi Keifer) was first discovered in Florida by Dr. A. K. Burditt, Jr
on calamondin at Orlando in 1961, ts
Economic Importance: Citrus rust mite is one of the major citrus pests in Florida.
It damages the leaves and russets the fruit (fig. 1). This mite is usually found
on the undersurface of mature leaves, on stems, and the protected side of fruit.
The citrus bud mite probably has been in Florida for many years along the coastal
areas. Apparently it causes little damage to Florida citrus, but does cause
damage to citrus buds (fig. 2), deforming the fruit and leaves in other areas.
It has been reported on lemon and sweet orange in California and on sweet orange,
grapefruit, and lemon in Florida. A pink citrus rust mite was found in Florida
recently but probably has been here much longer. It usually feeds on the upper-
surface of new leaves, and high populations deform leaves (fig. 3). This mite
shows a positive response to light.
Distribution: The citrus rust mite probably occurs in nearly every citrus-growing
area in the world. InFlorida,it is found throughout the citrus belt. The citrus
bud mite is found in Greece, Italy, Sicily and Spain in Europe; Cyprus, Indonesia,
Israel and Turkey in Asia; Congo, Kenya, Libya, Republic of South Africa, Southern
Rhodesia, Tunisia and Uganda in Africa; Argentina and Brazil in South America;
Australia; and the United States in California, Florida and Hawaiian Islands. In
Floridayit is found along the east coast at Miami and Ft. Pierce. A pink citrus
rust mite is known to occur in Greece, Italy, Japan, Sicily and Thailand. In
Florida, it is found in the following counties: Alachua, Baker, Citrus, De Soto
Hardee, Hillsborough, Lake, Marion, Orange, Pinellas, Putnam, Seminole, Volusia.
Host: All species are found on Citrus spp. and, with the exception of the citrus
bud mite, on Poncirus trifoliata.
Description: The color of the citrus rust mite (fig. 4a) is usually a lemon
yellow to brown. Diseased specimens may be pink or dark brown. The citrus bud
mite (fig. 5a, after Keifer) is slightly smaller than the citrus rust mite and is
light yellow in color. A pink citrus rust mite (fig. 6a) is approximately the
same size as the citrus rust mite and varies in color. It may be whitish, light
yellow, light pink to reddish. A key to mounted specimens of citrus rust mite,
citrus bud mite and a pink citrus rust mite is presented on the following page.

December calls for temperatures to average below seasonal normals over the
Southeast and also in the Northern Plains. Above normal averages are predicted
for the Great Lakes, Northeast, and also the Southwest. In unspecified areas
near normal averages are in prospect. Precipitation is expected to exceed
normal over the North and Middle Atlantic States as well as the Pacific Northwest.
Subnormal amounts are indicated for the Upper Mississippi Valley, West Gulf
States and Southwest. In the remainder of the Nation near normal amounts are
anticipated.

WEATHER OF THE WEEK ENDING NOVEMBER 18
Dry weather prevailed over the northern and central Great Plains and over most
of the southern half of the Nation. The light showers in those areas were of
little consequence. The main exception was in Florida where showers, ranging up
to 2 to 4 inches in the citrus areas, fell during the first half of the week.
The heaviest rains fell along the north Pacific coast where several stations
received more than 4 inches. Numerous stations near the southern and eastern
shores of the Great Lakes, in northern New York, and in northern and eastern
Maine received from 1/2 inch to an inch or more. Snow fell in the western
mountains, the northern Great Plains, near the Great Lakes, and, in the East,
from Maine to northern Alabama and Georgia. Caribou, Maine, received 15 inches
of snow. Other heavy falls occurred in other parts of New England, in New York,
in the northern and central Rocky Mountains, and in the Cascade and Olympic
Mountains. Temperatures averaged below normal from Mississippi to Ohio and
southeastward to the Gulf and Atlantic coasts. Temperatures at Tallahassee,
Florida, averaged 10° below normal. Over the rest of the Nation, temperatures
averaged above normal. Departures ranged up to +10° at Pocatello, Idaho, and to
+11° over central Washington.
Fair weather prevailed over most of the Nation at the beginning of the week. An
important exception was near the Great Lakes and eastward to the Atlantic Ocean.
Cloudiness and light rain or snow persisted over these areas in connection with
a low pressure area centered north of the Great Lakes. Brisk northerly winds
on the eastern side of a high pressure area centered over Saskatchewan, just
north of Montana, poured polar continental air over the northern Great Plains
holding afternoon temperatures in the 30's. On Wednesday afternoon, the
temperature at Bismarck and Minot, North Dakota, reached only 29°. The cold air,
blowing across the Great Lakes, produced showers and snow flurries along the
southern and eastern shores. A mass of maritime polar air pushed into the
Northwest during the first half of the week. It produced generous rains along
the coastal portions of Washington, Oregon, and northern California, and lighter
rains farther inland. Snow fell in the Cascade and Olympic Mountains above
3,000 feet.
By Friday morning the high pressure area was centered over Alabama and sub-
freezing temperatures occurred along the Gulf of Mexico and at some stations in
northern Florida. Tallahassee, Florida, and Augusta, Georgia, registered 23°
Friday morning. Snow flurries fell as far south as northern Alabama and Georgia
and continued in the northern Appalachians. By the weekend, southerly winds on
the western side of the high pressure area, brought warm moist air northward
over the Mississippi River Valley. Springfield, Missouri, registered 78°
Saturday afternoon. The mild temperatures spread northward and a few light
sprinkles fell over the central Great Plains. Heavier rains fell along the
northern Pacific coast and snow fell over parts of the northern and central
Rocky Mountains. Denver, Colorado, received 3 inches of snow Saturday evening.
At the end of the week, cloudiness prevailed in the Far Northwest, in the Lakes
region and eastward to New England, and along a cold front which extended from
near Lake Michigan southwestward to southern Texas. Elsewhere, skies were mostly
fair. (Summary supplied by U.S. Weather Bureau).

Name Change for Red-necked Peanutworm
Ronald W. Hodgesl/
Stegasta bosqueella (Chambers) is the name to be used for the red-necked peanut-
worm. Some confusion has occurred in the spelling of the trivial name because
Chambers (1875) originally used basqueella and subsequently (1878a, 1878b) used
bosquella, Two problems arise: 1) change from "a" to "o" and 2) deletion of an
Te’, The trivial name is based on the Texas county name, Bosque, and in the
original description Chambers misspelled that name as Basque. Because a
scientific name, either generic or trivial, based on the name of a person or a
place must be spelled in the same manner as the original, the correct spelling is
"bosque" rather than "basque". The second point concerns the suffix "ella". In
the Lepidoptera this suffix was used to designate members of the Tineina and was
added to the first part of the name. For ease of pronunciation and euphony the
name probably should be spelled bosquella; however, in the original description
no clue to this fact exists. Thus, Chambers made an invalid emendation in
changing the spelling from bosqueella to bosquella,.

INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES
BARLEY APHID (Cuernavaca noxius (Mordvilko) )
Economic Importance: This aphid has been a pest of small grains in areas of
southern Russia (U.S.S.R.) for many years. In the Crimea, this species caused
enormous damage in 1912, decreasing the harvest in the area infested by 75 percent.
Earlier, in 1900, it was responsible for a loss amounting to 76 percent of the
barley crop. The barley aphid only recently has been reported as a major pest of
small grains in Turkey where it caused heavy damage to wheat and barley in the
Konya area (south central) in 1962. It infested small grains throughout Libya
that same year, and a medium infestation of this species, Macrosiphum avenae and
Sipha agropyrella was reported in 1961 from Afghanistan on wheat. In the spring
of 1945, C. noxius heavily infested barley and wheat in the valley of Soton,
Huesca Province, Spain.
Damage by C. noxius is greatest when the crops begin to ripen, and numbers
increase substantially at that time. Damaged fields of small grains have a
purplish tinge. In the Crimea, the chief damage occurs in June, barley being
damaged greater than wheat because the latter crop is usually well developed and
the ears have partly emerged from the sheath. In heavily infested barley, the
development of the ear is delayed and the upper two or three leaves often do not
unfold. Damage may amount to a total loss of harvest in the case of young barley,
or to a considerable decrease in the case of wheat or older barley.
Synonymy: Brachycolus noxius Mordv.; Cavahylopterus graminearum Mimeur ; and
Cavahylopterus noxius (Mordv.).
Distribution: U.S.S.R. (Ukraine, Caucasus, Crimea, Kazakhstan), Turkey, Iran,
Afghanistan, Israel, United Arab Republic (Egypt), East Africa, Southern Rhodesia,
Libya, Morocco, Spain and Great Britain.
Hosts: Barley and wheat appear to be the most important. Also recorded on oats,
rice, corn, sorghum, brome, canarygrass, wheatgrass and other native grasses.
Life History and Habits: The biology as studied in the Crimea is as follows:
Aphids appear in the spring and live at the base of the inflorescence or inside
the sheath of the covering leaf when the colonies are small. Later, when the
crops ripen and the numbers increase, they concentrate on the green parts of the
plant, tip of inflorescence, or as low down as the first node of the stem. In June,
colonies consist of adult parthenogenetic wingless females, immatures and winged
colonizing females. In captivity, wingless individuals live 15 or 16 days and
winged ones 12 to 14 days. Migration of winged adults takes place usually during
the morning. Peak populations are present when the grain is nearly mature, with
numbers decreasing rapidly after harvest. Colonies subsist on the residue of the
crop or on native grasses for the remainder of the season. Sexual forms appear
the first part of October and are present until the first frosts, with the
resulting eggs hatching the next spring.
Description: Cuernavaca is similar to the genus Hyalopterus (rusty plum aphid,
H. pruni (Geoffroy) is an example), but differs in possessing short cornicles and
by the presence of a supra-caudal process on the eighth tergum, Cuernavaca noxius
(Mordvilko) WINGED FORM: Head: Light brown. Frontal tubercles not well developed;
compound eyes black. Antenna light brown, base of third segment lighter. Number
of sensoria on third and fourth antennal segments 6 (ranging 4-8) and 2 (ranging
1-3) , respectively; fifth segment without secondary sensoria. Apical rostral
segment without secondary hairs. Thorax: Brown. Wing venation normal. Legs
light brown; first hind tarsal segment with two hairs. Abdomen: Light green.
Aphidae, Hemiptera No. 160 of Series
- 1358 -
Lateral sclerites faintly indicated in mounted specimens; cornicles very short,
vasiform and light green. Cauda light green; anal plate brown. Supra-caudal
process present on eighth tergum with 2 hairs. (Prepared in Survey and Detection
Operations in cooperation with other ARS agencies.)

amounts ranged widely. Many places received only light amounts. Little Rock,
Arkansas, received 1.11 inches.
By Tuesday, a mass of arcticair began pouring into Montana and continued forward
to develop the country's first early winter storm. Temperatures plunged to 5
degrees to 10 degrees below zero at some stations in Montana, east of the
Continental Divide and at stations in North Dakota and South Dakota. Aberdeen,
South Dakota, registered 4 degrees below zero Saturday morning. The Weather
Bureau issued cold wave warnings for the northern Rocky Mountains and the
northern Great Plains. Stockmen were warned to protect their animals from snow,
wind and falling temperatures. Motorists were cautioned that hazardous driving
conditions might develop in areas of freezing rain or drizzle in Nebraska and
nearby portions of Minnesota and Iowa. Similar warnings were issued to stockmen
and drivers in Arizona and New Mexico. The Rocky Mountains and northern Great
Plains received snow Wednesday night. A 6-inch blanket of freezing snow covered
Flagstaff, Arizona, Thursday morning.
The stormy weather spread eastward and the cold temperatures pushed southward.
Livestock and traveler warnings continued in effect over the northern and central
Great Plains. Showers and thunder storms occurred over the southern central
stations. Most of the Nation received some rain on November 21.
Rains fell from the Great Plains to the Atlantic on Friday, with generous amounts
in the Mississippi and Ohio Valleys. On Saturday, the heaviest rains occurred
along the Atlantic coast where the cold front lay parallel to the coast. At the
end of the week, a new storm was bringing rain to the north Pacific coast and a
weak cold front lay across southern Florida. High pressure areas were centered
over the Great Basin and the Great Lakes.
Temperatures during the week averaged slightly below normal over California,
Nevada, Utah, Arizona, western New Mexico, eastern Montana and western Dakotas.
Temperatures ranged from -7 degrees at Red Bluff, California, to +14 degrees in
southern New York,
Generous rainfall occurred along the Pacific coast and in the western hills and
western slopes of the Sierra and Cascade Mountains, also part of the coast and
southern Great Plains and the Great Lakes region. Rainfall was generally light
over the Great Basin, the Rocky Mountains and the western part of the northern
Great Plains. Amounts ranged light over the East--mostly light but a few
scattered localities received a few showers or more. (Summary supplied by U. S.

STATUS OF THE SCREW-WORM (Cochliomyia hominivorax) IN THE SOUTHWEST
During period November 10 - 16, total of 200 confirmed cases, including one of
unknown origin, found in 55 counties in TEXAS; this is decrease of 149 cases and
14 counties over previous period's total. This is least number of cases
occurring in Texas since period ending September 21. A total of 19 confirmed
cases was reported from 10 counties in NEW MEXICO. The cold wave which moved
through Texas during day of November 7 probably caused an appreciable decrease
in fly activity; until November 13 and 14, cooler weather probably contributed
to decrease of fly movement in the Southwest. Screw-worm was reported for the
first time this year from Wharton and Limestone Counties, Texas. A total of
oe neat sterile flies was released during the period. (Anim. Dis. Erad,
Div.).

WEATHER BUREAU 30-DAY OUTLOOK
DECEMBER 1963
The Weather Bureau's 30-day outlook for December calls for temperatures to average
below seasonal normals in the southeast quadrant of the Nation. Above normal
temperatures are predicted for New England, the West Coast, and a large area
extending from the Western Lakes to the Northern Rockies. In regions not mentioned
near normal averages are in prospect. Precipitation is expected to be greater
than normal in Atlantic and Gulf Coastal States. Near normal amounts are
anticipated in a zone extending from the Eastern Lakes through the Ohio and
Tennessee Valleys into the Southern Plains. In unspecified areas near normal
precipitation is indicated.
Weather forecast given here is based on the official 30-day "Resume and Outlook"
published twice a month by the Weather Bureau. You can subscribe through the
Superintendent of Documents, Washington, D.C. 20250. Price $4.80 a year, $2.40
a half year.

WEATHER OF THE WEEK ENDING DECEMBER 6
High pressure and fair weather prevailed over most of the Nation at the beginning
of the week. There were a few exceptions. A storm approached the north Pacific
coast producing several inches of rain at Tatoosh Island, Washington, during the
first few days. Scattered snow flurries fell over the southern Rocky Mountains
and parts of the upper Mississippi River Valley. A cold front lay across southern
Florida. By about midweek, a wave had developed over the Gulf of Mexico and was
bringing generous rains to south Texas and the upper coast. This storm intensified,
moved northeastward, and by midweek was bringing heavy downpours over much of
southeastern United States. Jackson, Mississippi, and Montgomery, Alabama, were
among the locations that received more than 2 inches of rain on Thanksgiving day.
Another storm, which developed north of Montana, moved quickly to near Winnipeg,
Canada, on Wednesday and continued eastward to Sault Ste. Marie, Michigan, on
Thursday. This storm produced considerable cloudiness, a few snow flurries, and
strong gusty winds. By Friday morning, high pressure and fair weather prevailed
over the western two-thirds of the country and a deepening storm centered over
West Virginia brought heavy rains to the Atlantic Coastal States. Cold air, on
the back side of the storm, produced snow in the southern Appalachians as far
south as Knoxville, Tennessee. Most of the eastern third of the Nation received
generous rains as the storm intensified and moved northeastward and another storm
moved eastward across northern Lake Superior. Most of the northeastern quarter
of the Nation received rain or snow over the weekend. Snow accumulated to 9
inches in northern Pennsylvania.
At the end of the week, a high pressure area was centered over the northern Rocky
Mountains and temperatures dropped to 7° below zero at International Falls,
Minnesota. Subzero temperatures were also registered in Wyoming and South Dakota.
Temperatures dropped to freezing or lower in the Southeast in connection with a
high pressure area centered near Jacksonville, Florida. Tallahassee, Florida,
registered 28° Sunday morning and again on Monday.
Temperatures during the week averaged slightly below normal over parts of
Washington, Oregon, and California, over the southern Appalachians, and from
southeastern New Mexico eastward to Mississippi. Elsewhere, temperatures
averaged above normal. Temperature departures ranged from -6° at Brownsville
and Laredo, Texas, to +13° at Glasgow, Montana. Some generous rains fell
in northwestern Washington. Tatoosh Island, Washington, received 3.38 inches
during the week. Several stations in southern Texas received more than 1 inch
of rain. No rain of importance fell from California to Wisconsin and Illinois.
A few eastern areas received more than 2 inches. One of these stretched from
eastern Alabama to southwestern West Virginia. Rainfall also exceeded 2 inches
over eastern New England. There was considerable fog in the valleys in the
northern Rocky Mountains. (Summary supplied by U.S. Weather Bureau.)

HAWAIIAN INSECT NOTES
The following notes on Hawaii insect conditions were presented at the 695th
meeting of the Hawaiian Entomological Society held November 4, 1963.
A SCARAB (Onthophagus sagittarius (F.)) - Approximately 10 specimens collected
from cow dung in Manoa Valley, Oahu, July 24, 1963. This insect has not previously
been reported from Hawaii, but was probably released with O. catta. (See CEIR
10(23) :477). This constitutes a new record for the State. Det. by
Opel eeCartwright..(D. Mi. ‘Tsuda)i<
A PHYCITID MOTH (Ectomyelois ceratoniae (Zeller)) - Two larvae found infesting
seeds of Barringtonia sp. from Oahu on March 10, 1963, by J. Toba. Determination
confirmed by D. M. Weisman. This constitutes a new host record for this insect.
(E, H. Davidson, E. S. Shiroma).
A PHYCITID MOTH (Ephestiodes gilvescentella Ragonot) - An adult was taken ina
blacklight trap at Olinda, Maui, by E. Bonsey. Det. by W. D. Duckworth.
Zimmerman (1958: Insects of Hawaii 8:377) records this species as occurring on
the islands of Oahu and Molokai. This constitutes a new record for the island of
Maui. (E. H. Davidson, E. S. Shiroma).
A LYGAEID BUG (Graptostethus manillensis (St&l)) - On August 31, 1963, a specimen
was intercepted from box of assorted cut flowers from Hilo, Hawaii, enroute to
the mainland by R. Nave. Although previously reported from the islands of Kauai,
Oahu, Maui and Niihau, this interception constitutes a new record for the island
of Hawaii. (E. H. Davidson, E. S. Shiroma).
A REDUVIID BUG (Polididus armatissimus Stal) - A specimen was taken August 29,
1963, at a light in Foster Village, Oahu, by J. Gayden. This is third locality
record of this species on Oahu. It was first reported by Dr. C. R. Joyce in
October 1961 as being taken at Aina Haina and at Kailua. This species was first
reported from the State on the island of Hawaii by LeMar Chilson in 1953.
(E. H. Davidson, E. S. Shiroma).
A PUNCTURE-VINE WEEVIL (Microlarinus lypriformis (Wollaston)) - The work of this
stem-infesting species was exhibited. This weevil, the second species introduced
for the biological control of puncture-vine (Tribulus terrestris and T. cistoides);
was sent from California by Noel Krauss and released at Kekeha, Kauai, on July 8,
1963. Much damage to the native puncture-vine (T. cistoides) has occurred since
release of the weevil. (S. Au, C. J. Davis). ae
A PARASITIC ENCYRTID (Exoristobia philippinensis Ashmead) - Reared from puparia
of Trichopoda pennipes F. (a parasitic tachina fly) at the Honaunau Insectary,
Kona, recently. This is first record of this hyper-parasite from island of
Hawaii. The species was previously reported from Oahu by J. W. Beardsley and
Cham Davis. (Cs J.) Davis, Ei. Yoshioka) .
A HELIODINID MOTH (Schreckensteinia festaliella Hubner) - This leaf-skeletonizing
species, introduced from Oregon for control of blackberry, was approved for
release by the Board of Agriculture and Forestry at its meeting on October 25,
1963, after extensive host range tests indicated the species was host specific.
First releases made the following week in Olinda, Maui. S. festaliella is of
European origin. (C. J. Davis). a

Comment: Adequate rainfall came in October of 1961 for the fall sown grains, but heavy. rains
in January with subsequent freezing temperature resulted in the smothering of part o e crop,
which gave higher losses of acreage than usual. Timely rainfall in late May resulted in
excellent development of the heads. The yield of 32 bushels per acre was the secon ghes
on record.

INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES
SAFFLOWER FRUIT FLY (Acanthiophilus eluta (Meigen) )
Economic Importance: The safflower fruit fly (Acanthiophilus eluta (Meigen)
E A. helianthi (Rossi)) is historically one of the most important pests of safflower
in the Old World, and is readily found breeding on native composites over most of its
range. It has been reported as the most important pest of safflower in southeastern
U.S.S.R., and up to 90 percent of the fruits become infested in Rumania. About the middle
of March 1939, larvae of A. eluta were found seriously damaging the flower heads of
some varieties of safflower in experimental plots at New Delhi, India. Serious damage
was reported to both early and late-sown varieties, the infestation being as high as
90 percent. Safflower was introduced into the south of France as an oilseed crop in
1942, but was so severely attacked by this fruit fly that by 1953 it had almost ceased
to be grown. Losses of 40-50 percent were observed at Tarascon in 1958, and 90-95
percent of the flower heads of an experimental crop at Montfavet were attacked in 1959.
The maggots of A. eluta feed upon the essential organs of the florets and even bore into
the torus (receptacle) of safflower. The infested bud begins to rot and the fluid thus
produced oozes out from its apical portion and gives it a damp appearance. Furthermore,
in advanced stage of attack, the florets become black, presenting an emaciated and
withered appearance.
In 1961, safflower, as an oil crop, was being grown on about 420,000 acres in the United
States, about half of which was in California. By 1962, production was expected to
increase to about one-half million acres. Based on the rapidly increasing safflower
acreage, A. eluta may be a potential threat if introduced in the United States.
Distribution: Ranges from England and the Canary Islands across southern and central
Europe and North Africa (from Morocco to the Sudan, Ethiopia (Eritrea) and Kenya) to
Turkey, Israel, Iran, U.S.S.R., India, and the Northwest Himalayas.
Hosts: Recorded on safflower (Carthamus tinctorius), C. lanatus, centaurea (Centaurea
spp.), bristlethistle (Carduus spp.), bull thistle (Cirsium lanceolatum) , Cnicus
lanceolatus, illyrian cottonthistle (Onopordum illyricum) , Leuzea conifera, blessed
milkthistle (Silybum marianum) and other wild hosts of the tribe Cynareae, Compositae.
Life History and Habits: The biology as studied in France was as follows: Two
generations a year are produced. Females appeared in late May and early June and
oviposition occurred in June, the eggs being laid in batches of 6-20 in slits cut with
the ovipositor in the lower part of the bracts of the young flower heads. Larvae
hatched in 1-2 days and fed in heads, completely hollowing them out. Larval development
lasted 8-12 days, and pupation took place in the flower head; adults emerged 9-10 days
later. As the flower heads developed, eggs were laid in the upper part, and the damage
done by the larvae was then less extensive; some florets survived to set seed. The
first-generation adults emerged at the end of June, at which time the flowers were
opening. Eggs were laid in July and larvae developed, but the damage by the second
generation was relatively unimportant.
Earlier studies in India stated that the pest was very active during March, April and
May in the field. Laboratory studies to determine the duration of the various stages
(average of 5 readings) at maximum and minimum temperatures of 85.2° F. and 78.5° F.,
respectively, were made. The egg stage lasted 25 hours and larval and pupal stages 7
days each. In the safflower season, the fly completed 3 generations in 6 weeks, from
the middle of March to the first week of May. Additional generations occur on wild
hosts during the growing season.
Life history studies in U.S.S.R. by Rusanova (6), though incomplete, suggest that
A. eluta may overwinter as an adult.

Description: LARVA - Full-grown stage 5 mm, long and 1.5 mm. wide; shape typical of
tephritids. Anterior spiracles cup-shaped, margin of each spiracle being fringed with
6 oval lobes. Posterior spiracles almost reniform, each possessing 3 elongated oval
slits which are notched at peripheral end. Inner walls of slits chitinized and
fimbriated. In each inter-spiracular area, 1 to 4 very minute hyaline lanceolate
processes present. Apical tooth of oral hooks curved and pre-apical tooth, which is
smaller and less curved, directed downwards and somewhat backwards. PUPARIUM - 4.25 mm.
long and 1.75 mm. wide; barrel-shaped and black with a metallic tinge. ADULT - Frons
bare with trace of median stripe. Wing pattern reduced and variable, occasionally
almost absent. Apical scutellar bristles about 0.3-0.4 times as long as basals.
Coloration of body ash, with reddish-brown frons and light brown legs. Male smaller
than female, which is about 6.5 mm. in length. Male - Sternite 4 wider than 5, which
has a shallow indent and a distinctive, narrow median ridge on inner side, a slight
ridge may appear on 4. Aedeagus vesica moderate, a large basal curved spine and a
moderate setose rod. (Prepared in Survey and Detection Operations in cooperation with
other ARS agencies.)
Figures of Acanthiophilus eluta (Meigen): A - Adult female. B - Wing, showing
variable pattern. C - Aedeagi, showing variation of setulae on rod (small

WEATHER OF THE WEEK ENDING DECEMBER 9
High pressure, light winds, and clear skies continued over most of the western
half of the Nation during the first part of the week. Fog blanketed the Pacific
coast and morning fog filled some valleys in the Pacific Northwest. Stormy
weather continued over most of the eastern half of the country. Rain or drizzle
fell from Virginia southward to northern Florida and snow fell from Iowa eastward
to New England. Subfreezing temperatures combined with the snow caused hazardous
driving conditions on some highways in the Northeast. The Weather Bureau issued
heavy snow warnings for parts of the Northeast and frost warnings for parts of
northern Florida. Snow accumulated to depths of 5 inches or more at some places
in Pennsylvania, New York, and New England. By Wednesday morning the snow was
10 inches deep at Rumford, Maine. Cold temperatures pushed southward to the
Gulf. Tallahassee, Florida, registered 28° on Wednesday morning. At midnight
Wednesday, the temperature at Watertown, New York, had dropped to 0°. Cool
temperatures prevailed over the West also. Santa Maria, California, registered
32° on Thursday morning.
As the weekend approached, the weather over the Northwest became unsettled. A
storm developed over Montana, moved eastward, and intensified. A cold front
stretched southward. The front produced rain showers in the warm moist air which
moved northward ahead of the front. Behind the front, gusty north winds, with
speeds of 30 to 50 m.p.h., dropped the temperatures far below freezing as heavy
snow blanketed the upper Mississippi River Valley. Snow depths reached 8 inches
in some areas in the northern Great Plains. The Weather Bureau issued heavy
snow warnings to stockmen and travelers in the Dakotas, Minnesota, Nebraska, and
Iowa. Gusts reached 75 m.p.h. at points in Nebraska, Iowa, and Kansas. As the
storm moved eastward, the warnings were extended to include parts of Wisconsin
and Michigan. A new storm moved into the Northwest over the weekend. It
intensified and brought heavy snows and blizzard conditions to several western
States from Nevada to Nebraska and Kansas and from Oregon to Arizona.
Precipitation exceeded 1.00 inch at a few stations in the Pacific Northwest, at
New Orleans, Louisiana, and at a few scattered stations between southern New
York and Hatteras, North Carolina. No rain of importance fell from Nevada to
Nebraska and southward to Mexico and the Gulf. Elsewhere, precipitation ranged
mostly from a few hundredths to about 1/2 inch. Temperatures averaged below
normal over most of the area west of the Continental Divide, over the southern
Great Plains, the Gulf States, the Atlantic States, and along the shores of
Lake Michigan. Temperatures averaged above normal over the southwestern deserts
and over the northern and central Great Plains. Temperature departures ranged
from -8° at Sacramento, California, to +10° over parts of the Dakotas. (Summary

BARK BEETLES - VIRGINIA - Potentially explosive infestation reported in CEIR 13
(44) :1295 (PINE BARK BEETLES) found to be predominantly Ips grandicollis in an
estimated 50 percent of infestations in combination with Dendroctonus terebrans.
Ips spp. noted in Dinwiddie County in loblobby and in shortleaf pine in Brunswick
and northwest Greensville County. Numerous outbreaks noted throughout these
counties but not many east of Stony Creek. Ips bark beetles killed 5 Virginia
pines in Fluvanna County and appeared more evident in both shortleaf and loblolly
pine in Amelia (3 tracts), Charlotte (1 tract), Nottoway (12 tracts) and Lunenburg
Counties (numerous tracts). Infestations ranged in size from 6 to 25 trees.
Mortality to loblolly pine in King William (8 spots, up to 30 acres in size),
Chesterfield (4 spots, up to 18 trees per spot) and Hanover Counties (4 spots, up
to 20 trees in size) reported due to Dendroctonus frontalis. Five Virginia pines
in Albemarle County reportedly killed by this species and continuing activity
noted in several spots in each of Charlotte, Nottoway, Prince Edward and

visible damage by D. frontalis and D. terebrans reported increasing in Chesterfield
and Hanover Counties. D. frontalis remains active mainly in Accomack County in
loblolly pine and to a lesser extent (5 new spots) in Northampton County. Death
of loblolly pine in several tracts in Chesterfield and Hanover Counties caused
by Dendroctonus spp. (30 ‘trees minimum per spot). Activity and visible damage by
both D. frontalis and D. terebrans reported to be increasing. Found infesting
several small groups (1-6 trees) of shortleaf pine in Lunenburg County and notably
active on one 4-acre tract of white pine in Grayson County, causing extensive

HIGHLIGHTS OF THE OCCURRENCE OF INSECTS AND OTHER ARTHROPODS
IN CANADA, 1963
C. Graham MacNay
The following are some of the more important records of the occurrence of
arthropod pests in Canada in 1963.
In much of the agricultural area of the Prairie Provinces, GRASSHOPPERS again
occurred in outbreak numbers, but several factors combined to restrict crop
losses sufficiently to permit the harvesting of a record crop of grain. In the
more southern areas of Alberta, in Saskatchewan, and in northwestern agricultural
areas of Manitoba, where grasshopper population densities were greatest, prompt
and extensive control measures were carried out. In Alberta, good rains toward
the end of June removed the threat of major damage. In Saskatchewan and Manitoba,
extended periods of wet weather prolonged hatching, retarded nymphal development,
and stimulated plant growth. Furthermore, the incidence of the fungus disease,
Entomophthora grylli, was widespread. In Manitoba, in comparison with 1962, there
was a reduction of approximately 80 percent in the area infested and 90 percent in
overall population density.
In Alberta, southward from Drumheller, infestation of nearly all wheat by the
ARMY CUTWORM (Chorizagrotis auxiliaris) was the heaviest in several years. In
Saskatchewan, infestation was the heaviest and most widespread ever recorded,
involving all of the southwestern area of the Province, but by delaying seeding
and applying insecticides, crop losses were minimized. In Alberta, infestation
by the PALE WESTERN CUTWORM (Agrotis orthogonia) was the heaviest in many years.
Severe damage, accentuated by drought conditions, made much reseeding necessary
in the Lethbridge and other areas. In Saskatchewan, damage was moderate in
southwestern and west central areas and lighter than in 1962, In Saskatoon,
unusual infestations of GLASSY CUTWORM (Crymodes devastator) and BRONZED CUTWORM
(Nephelodes emmedonia) injured lawns, and the RED-BACKED CUTWORM (Euxoa ochrogaster)
was moderately numerous in gardens. In Ontario, VARIEGATED CUTWORM (Peridroma
saucia) severely attacked tobacco as seedlings in greenhouses and in midsummer
in the field, DARK-SIDED CUTWORM (Euxoa messoria) severely damaged tobacco
generally, BLACK CUTWORM (Agrotis ipsSilon) in a few plantings and SPOTTED CUTWORM
(Amathes c-nigrum), not a pest of tobacco in recent years, caused some damage.
The DARK-SIDED CUTWORM injured corn in Norfolk County and unidentified species of
cutworms fed on trefoil in Lambton County. In Nova Scotia, the VARIEGATED CUTWORM
injured beets in the Sydney area,
In Manitoba, five times the normal population of SIX-SPOTTED LEAFHOPPER
(Macrosteles fascifrons) damaged flax, wheat, and barley; caused almost total loss
of unsprayed head lettuce; and reduced yields of carrots by 35 percent, celery by
25 percent and onions by 5 percent. In Ontario and Quebec, populations were
unusually small. In Prince Edward Island, losses in untreated lettuce ranged from
25 percent to 90 percent.
In British Columbia, the CLOVER SEED WEEVIL (Miccotrogus picirostris) was found
in the Peace River district near Dawson Creek. In Alberta, 12,000 acres of sugar
beets were treated for SUGAR-BEET ROOT MAGGOT (Tetanops myopaeformis) and FLEA
BEETLES (Phyllotreta spp.) were injurious. Other pests of this crop were not
numerous, nor were WIREWORMS and the WHEAT STEM SAWFLY (Cephus cinctus) in general.
FLEA BEETLES severely damaged rapeseed and mustard crops in the Prairie Provinces,
much spraying being necessary in northern areas, In southern Alberta, the SAY
STINK BUG (Chlorochroa sayi) occurred in the largest numbers in 20 years. At
Estevan and Wynyard, Saskatchewan, THRIPS (presumably Limothrips denticornis)
attacked barley in a record outbreak. HESSIAN FLY (Phytophaga destructor) heavily
infested wheat in the Regina Plains and other areas of Saskatchewan and in
Manitoba, the first outbreak in many years. The CORN LEAF APHID (Rhopalosiphum
maidis) and drought destroyed much barley in the Red River Valley. The recently
described mite, Tetranychus sinhai, was found on barley, wheat and rye in western
- 1402 -
Canada. Infestation of corn by the EUROPEAN CORN BORER (Ostrinia nubilalis)
increased in southern Manitoba, was very light in southwestern Ontario and light
to moderate in southern Quebec. ROOT MAGGOTS (Hylemya spp.), largely insecticide
resistant, severely injured germinating corn, beans and peas and tobacco seedlings
in Ontario and Quebec. In southern Ontario, populations of the NORTHERN CORN
ROOTWORM (Diabrotica longicornis) were the largest on record and leatherjacket
larvae, prob. Nephrotoma sodalis, attacked tobacco. At Niagara Falls, the
EUROPEAN CHAFER (Amphimalon majalis) severely injured sod in lawns, parks, and
cemeteries. In Prince Edward Island, the BARLEY JOINTWORM (Harmolita hordei)
was very scarce, probably decimated by low winter temperatures. In Newfoundland,
the CRANE FLY (Tipula paludosa) heavily infested hay and pasture at Colinet.
Throughout the lower mainland of British Columbia and on Vancouver Island,
insecticide resistance was general in ROOT MAGGOTS, Total loss of all crucifers
occurred in some areas. The CARROT RUST FLY (Psila rosae) was again becoming
common and for the first time destroyed some celery crops. .Damage by the GARDEN
SYMPHYLAN (Scutigerella immaculata) continued to increase. The CABBAGE APHID
(Brevicoryne brassicae) waS unusually injurious and difficult to control. The
BEET LEAF MINER (Pegomya betae) damaged beets, spinach and lambsquarters in the
Kamloops area. In southern Ontario, Hylemya florilega (=H. liturata) was
unusually numerous and damage to seeded garden crops, transplants, and potatoes
was extensive. The MEXICAN BEAN BEETLE (Epilachna varivestis) , spreading
steadily, was numerous as far north as Clinton. In southern Quebec, WIREWORMS
severely damaged potatoes in organic soils and SLUGS were unusually injurious in
gardens. At Maugerville, New Brunswick, the POTATO STEM BORER (Hydroecia micacea)
damaged rhubarb extensively. In Prince Edward Island, CABBAGE MAGGOT (Hylemya
brassicae) was numerous in young turnips early in the season. In Newfoundland,
organic phosphates against ROOT MAGGOTS enabled growers to resume production of
cruciferous crops.
In coastal British Columbia, larvae of the BLACK VINE WEEVIL (Brachyrhinus
sulcatus) and a small OECOPHORID CATERPILLAR (Dasystoma salicellum) were problem
pests in blueberries. In the Okanagan, weather conditions were generally
unfavorable to orchard pests, but the European red mite (Panonychus ulmi)
flourished, In southern areas of Ontario and Quebec, too, this mite was the major
pest of fruit trees. In Ontario, APPLE APHID (Aphis pomi) also was numerous but
other apple pests were scarce. In southwestern Quebec, APPLE MAGGOT (Rhagoletis
pomonella) persisted in large numbers but other insects were of minor importance.
In the Annapolis Valley, Nova Scotia, the WINTER MOTH (Operophtera brumata)
continued to be numerous in apple orchards, but APPLE MAGGOT, increasing in recent
years, decreased sharply in numbers,
Other occurrences of note included: In British Columbia, the smallest numbers of
FLOODWATER MOSQUITOES in many years and the continued spread of the 4 to 5-inch
introduced SLUG (Arion ater); in northern areas of the Prairie Provinces, a
continuation of the severe FOREST TENT CATERPILLAR (Malacosoma disstria) outbreak;
in Alberta, increased numbers of a BLACK WIDOW SPIDER (Latrodectus curacaviensis) ,
and severe attacks on livestock by a BLACK FLY (Simulium arcticum) in the
Athabasca area; in southern Saskatchewan, MOSQUITOES very numerous, 190 reported
cases of equine encephalitis (31 fatal), 28 cases in humans to Oct. 7; in Manitoba
severe outbreaks of FALL CANKERWORM (Alsophila pometaria) and ASPEN LEAF BEETLE,
(Chrysomela crotchi); in Ontario, unusual outbreaks of LARDER BEETLE (Dermestes
lardarius) in buildings, usually associated with infestations of CLUSTER FLY
(Pollenia rudis) and FACE FLY (Musca autumnalis), and of STRAWBERRY ROOT WEEVIL
(Brachryhinus ovatus) entering buildings, heavy infestations of the FACE FLY on
livestock, and large numbers of AMERICAN DOG TICK (Dermacentor variabilis) in
the Hagersville area. ‘

WEATHER OF THE WEEK ENDING DECEMBER 16
At the beginning of the week, a vigorous storm centered over the Great Lakes region
was causing strong, gusty winds and snow flurries from the upper Mississippi
River Valley eastward to the Appalachians. Another storm brought rains from
central California northward and rain or snow over the Pacific Northwest and
Rocky Mountains. This storm intensified as it moved eastward. It produced heavy
snow over the northern half of the Country from the Rocky Mountains eastward to
the Atlantic. Temperatures over the Rocky Mountains dropped to zero as far south
as northern New Mexico. Subzero temperatures occurred over the Great Plains as
far south as Oklahoma. Freezing temperatures reached the Gulf of Mexico.
Tallahassee, Florida, registered 23° Tuesday morning. The Weather Bureau issued
heavy snow and glaze warnings to help protect stockmen and travelers.
By Saturday morning, the storm had moved eastward to the Atlantic and the leading
edge of the Arctic air had pushed its way to the Gulf of Mexico. A new wave
developed over the northern Great Plains and cold temperatures continued through-
out the United States. Light precipitation continued over the northern part of
the Nation from Washington to New England. As the storm moved eastward, high
pressure dominated mid-America, Subzero temperatures pushed southward.
Kirksville, Missouri, registered 10° below zero and Bemidji, Minnesota, registered
36° below zero Monday morning. At the end of the week, winter gripped the entire
Nation. A new storm in the Far Northwest was bringing rain along the coast and
snow at higher elevations. Scattered flurries occurred over the northern and
central Great Plains, with heavier snow in, the lee of the Great Lakes. In
southern Florida, where afternoon temperatures had been in the 80's, the
temperatures rose no higher than the 70's on Sunday.
Temperatures for the week averaged below normal over the entire country, except
at Key West, Florida. Most of the northern and central Great Plains averaged
colder than 15° below normal. Precipitation exceeded 1/2 inch over New England
and 1 inch over the extreme Northwest. Over the southeastern quarter of the
Nation, precipitation ranged from 1 to 4 inches. Several stations received
slightly more than 4 inches during the week. Other areas of the United States
received little or no precipitation. Snow fell as far south as the northern
portions of the Gulf States and freezing rain fell in the central parts of those
States. At the end of the week, the northern half of the country was covered by
snow which ranged from 2 to 10 inches deep generally, but to far greater depths
in the western mountains. (Summary supplied by U.S. Weather Bureau.)

CEREAL AND FORAGE INSECTS
GREENBUG (Schizaphis graminum) - OKLAHOMA - Populations of 200 per linear foot
present in localized area of Payne County. Heavy populations also reported in
isolated sandy land areas of Logan County; ranged 50-200 per linear foot; 2 fields
sprayed in this area. Counts ranged 1-4 per linear foot in northwest; fewer than

CHINCH BUG (Blissus leucopterus) - KANSAS - Annual hibernation survey completed.
Samples of bunch grass collected during late November in 58 counties in 6
districts of State. The highest average numbers of hibernating bugs per square
foot of bunch grass were in Linn County, east central area (1,636), and in
Montgomery County, southeast area (1,419). These are both severe ratings.
Marshall County, northeast area, had an average of 646 bugs per square foot;
Sumner County, south central area, had 614; and Shawnee County, east central, had
525. These are all moderate ratings. In northeast area, Pottawatomie County had
427, Jackson County had 423 and Nemaha County had 393; in central area, McPherson
County had 335. These are all light ratings. All other counties surveyed had
average counts of less than 250 bugs per square foot of bunch grass, or non-
economic ratings. (Bell, Peters).
THREE-CORNERED ALFALFA HOPPER (Spissistilus festinus) - ARIZONA - Adult counts
per 100 sweeps in alfalfa averaged 20 in Yuma County and 33 in Maricopa and
Pinal Counties. (Ariz. Coop. Sur.).

damaging oats in Comal County. (Shaver).
- 1406 -
FRUIT INSECTS
PEACH TREE BORER (Sanninoidea exitiosa) - ALABAMA - Quite heavy and active on
untreated peach, plum and cherry in State. Few 3-year-old plums dug and examined
revealed average of 5 larvae per tree, with hidden girdling covering 50 percent
of underground trunk area. Large amounts of "gum", mostly at ground level and
beneath, reveal infestations. (McQueen).
SCHOENE SPIDER MITE (Tetranychus schoenei) - GEORGIA - Light on peach trees in
Houston County. (Pollard, Sept. 13).
Citrus Insect Situation in Florida - End of November - On leaves, CITRUS RUST
MITE (Phyllocoptruta oleivora) infested 78 percent of groves (norm 71 percent) ;
66 percent economic (norm 47 percent). On fruit, CITRUS RUST MITE infested 66
percent of groves (norm 70 percent); 49 percent economic (norm 47 percent).
Population on leaves highest on record for November due to extremely high
infestations in groves damaged by cold last December. Those groves also have
high infestations on fruit. Population on fruit decreasing to normal level but
will remain high on leaves. Highest districts Brooksville, Bartow, west coast,
upper east coast and Gainesville. TEXAS CITRUS MITE (Eutetranychus banksi)
infested 59 percent of groves (norm 30 percent); 25 percent economic (norm 13
percent). Population continues to be higher than in any prior November, with
cold-damaged groves having heavier infestations. Decrease is expected in
December. Highest districts Gainesville, upper east coast, west coast and
Brooksville. CITRUS RED MITE (Panonychus citri) infested 50 percent of groves
(norm 54 percent); 24 percent economic (norm 24 percent). This mite near moderate
level typical of November. Few heavy infestations will occur in cold-damaged
groves. Highest districts Brooksville and west coast. PURPLE SCALE (Lepidosaphes
beckii) infested 82 percent of groves (norm 72 percent); 19 percent economic
(norm 6 percent). GLOVER SCALE (L. gloverii) infested 68 percent of groves (norm
28 percent); 18 percent economic (norm 1 percent). CHAFF SCALE (Parlatoria
pergandii) infested 73 percent of groves (norm 43 percent); 20 percent economic
(™morm 1 percent). YELLOW SCALE (Aonidiella citrina) infested 38 percent of groves
(norm 11 percent); 6 percent economic (norm I percent). The above scale species
continue to be above normal abundance; however, only few scattered groves have
important infestations. Decrease is expected, except for YELLOW SCALE, which may
increase slightly. Pinnaspis strachani is above normal abundance in east coast
groves. It is of little importance at this time. WHITEFLIES are decreasing but
still are above average level. (W. A. Simanton (Citrus Expt. Sta., Lake Alfred)).
CITRUS RUST MITE (Phyllocoptruta oleivora) - FLORIDA - Light on leaves of several
thousand sweet orange Surveyed December 3-10 at Dundee, Babson Park and Bowling
Green, Polk County; Weirsdale, Marion County; Dade City, Pasco County; and Avon

A LEAF ROLLER MOTH (Platynota stultana) - ARIZONA - Young larvae found in rolled
leaves of citrus in nursery in Yuma County. (Ariz. Coop. Sur.).
HICKORY SHUCKWORM (Laspeyresia caryana) - ALABAMA - Examination of pecan shucks
on ground in numerous Lee County orchards revealed extremely high larval popula-
tion in shucks; some infestations as high as 1-2 larvae per shuck. Nut yield
extremely high this year in State. An estimated one-half to 5 million larvae per
acre of orchard going into winter months in old shucks in many orchards. Pupation
should occur in March and April of 1964. (McQueen).
FIG SCALE (Lepidosaphes ficus) - CALIFORNIA - Immature forms infesting fig trees
locally in Sacramento, Sacramento County. This pest is generally kept under
economic levels by parasites in most areas of State. (Cal. Coop. Rpt.).
- 1407 -
TRUCK CROP INSECTS

but have not caused as much alarm in flight as some 10 days previously in some
areas of State. Cars and equipment under affected trees heavy with honeydew.
Adults and larvae of Hippodamia convergens continue to feed in abundance, along
with syrphid fly larvae; aphid populations fairly well destroyed in some instances.

Boll Weevil Hibernation Surveys in North and South Carolina, Tennessee,
Mississippi, Louisiana and Texas - Fall 196
The fall collection of surface ground (woods) trash samples (two square yards per
sample) has been completed in 6 Southern States by State and Federal agencies to
determine the number of boll weevil (Anthonomus grandis) adults that went into
hibernation. The same areas were sampled as in the fall of 1962, and wherever
possible, the samples were taken from locations that could be sampled again next
spring. A total of 3 samples was collected at each location in the Carolinas,
Mississippi, Louisiana and Texas; 20 samples were taken in McNairy County,
Tennessee, In North and South Carolina, 30 locations were sampled, with the
number of counties per area from which samples were taken varying from 3 to 6.
In Mississippi, 90 samples were taken with either 7 or 8 locations being sampled
in each of the 4 areas. A total of 40 locations was sampled in northeastern
Louisiana; 10 each in East Carroll and Tensas Parishes and 20 in Madison Parish.
In Texas, 75 samples were taken, with either 6 or 7 locations being sampled in
each of 4 counties.
Average counts (live weevils per acre) exceeded those of 1962 only in area 1 of
the Carolinas (south central South Carolina) and in the tri-parish area of north-
eastern Louisiana, In all other areas sampled, average counts were lower than
in the fall of 1962.
In Florence County, South Carolina, the number of weevils per acre (11,406) is
1.8 times the average for the 21 years that such examinations have been made,
This is the fourth consecutive year in which over 10,000 weevils per acre have
been found in the fall examinations in this county.
McNairy County, Tennessee, was chosen again this year for the survey in that
State because it usually represents the heaviest infestations found in the
southern tier of counties. The other southern counties usually support only
slightly lower infestations than that of McNairy County. The number of weevils
per acre was 1,089 compared with 3,633 in 1962, 3,025 in 1961, 2,622 in 1960,
ioo2 an 1959, 1) 204 in 1958), 25365 in 1957, 933 in 1956, 902 in 1955, 3112 in
1954, 31 in 1953, 2,259 in 1952 and 239 in 1951.
The 1963 State average of 3,010 in Mississippi was less than half the average for
the past 5 years, 7,526 weevils per acre.
The average number of boll weevils per acre in the tri-parish area of northeast
Louisiana was 7,317. The average by parish was 6,295 in Madison, 10,249 in East
Carroll and 5,407 in Tensas. During the past 9 falls that these records have
been made in the tri-parish area, the number of weevils per acre has ranged from
2,622 to 13,433 and averaged 6,044 in Madison Parish; 5,165 to 13,235 and averaged
8,746 in East Carroll Parish; and 0 to 17,593 and averaged 7,043 in Tensas Parish.
During the past 28 years that similar records have been made in Madison Parish,
there have been only 3 years in which a larger number of weevils has been found
in ground trash in the fall than the 6,295 found in 1963, Field conditions were
equally favorable, or perhaps even better, this fall for collecting ground trash
samples in northeast Louisiana than any fall during the 28 years that these
studies have been in progress.
The area average of 517 boll weevils per acre in the fall of 1963 in central
Texas compares with averages of 1,781 in 1962, 4,114 in 1961, 4,501 in 1960 and
6,631 in 1959, The decrease in numbers entering hibernation in 1963 was due
primarily to the low numbers present in the spring to infest the 1963 crop; the
very hot, dry growing season; and early maturity, harvest and stalk destruction.

HAWAIIAN INSECT NOTES
The following notes on Hawaii insect conditions were presented at the 696th
meeting of the Hawaiian Entomological Society held December 9, 1963.
A SUBTERRANEAN TERMITE (Coptotermes formosanus Shiraki) - A queen was found
December 2 by Donald Yara. The carton nest of about 2 cubic feet of material was
in the false bottom of a closet directly on the concrete slab near the bathroom.
No tunneling was found leading to the ground. In dissecting away parts of the
nest in order to remove the queen, hundreds of soldiers and small nymphs were
observed but no eggs. There were many thousands of workers present. The queen
and a large part of the colony are being held in a crisper dish in the insectary.
(H. B. Bess, Univ. of Hawaii).
A PARASITIC TACHINA FLY (Trichopoda pennipes F.) - Eggs of this parasite found
on a scutellerid bug (Coleotichus blackburniae White) which was collected on
November 3, 1963, at the Tantalus park, Oahu. T. pennipes was introduced for
the control of the southern green stink bug (Nezara viridula (L.)).
(B. D. Perkins, Univ. of Hawaii).
A REDUVIID BUG (Polididus armatissimus St&l) - Collected on 6 to 8 occasions
from different areas of Oahu. Specimens present in collections of insects made
by general entomology students at the University of Hawaii. Species now apparently
widespread throughout the island. (J. W. Beardsley, Univ. of Hawaii).
A DIASPID SCALE INSECT (Clavaspis herculeana (Doane & Hadden)) - Found on plumeria
cutting during predeparture baggage inspection on May 18 by R. Wakamiya. Det.
by R. F. Wilkey. This is a new State record. (E. S. Shiroma, PQ, ARS, USDA).
SOUTHERN GREEN STINK BUG (Nezara viridula (L.)) - Found attacking growing tips of
Guiana-chestnut pachira (Pachira aquatica); a new host record for species.
(W, C. Mitchell).

Survey to Determine the Oviposition and Hatching Records of (4)
the Alfalfa Weevil in Massachusetts During the Fall of 1963‘?
F. R. Shaw 62)
During the 1963 season, an alfalfa field in New Marlboro, Massachusetts, was
found to be heavily infested by the alfalfa weevil (Hypera postica (Gyll.)).
This field had received no insecticide treatment and was not cut after the middle
of August. Hence it presented a good opportunity to obtain information on the
fall activities of the weevil.
Adult weevil populations were low during the period from August 15 to September
5 after which they began to increase. In early October, an examination of fifty
stems for oviposition was begun which was continued until November 10. The stems
were randomly collected, brought to the laboratory and carefully examined for
oviposition punctures. When a puncture was found, it was opened and the cavity
below examined for eggs. The data obtained are summarized in Table I.
It is of interest that newly hatched alfalfa weevil larvae were observed as late
as October 31. On November 10, one lot of eggs was observed containing mature
embryos but no newly hatched larvae were found; also newly laid eggs and recently
emerged adults were found on this same date.
It is recognized that the month of October was unusually warm for Massachusetts.
No doubt this influenced the oviposition and other activities of the alfalfa
weevil.

WEATHER BUREAU'S 30-DAY OUTLOOK
MID-DECEMBER 1963 TO MID-JANUARY 1964
The Weather Bureau's 30-day outlook for the period from mid-December to mid-
January calls for temperatures to average below seasonal normals over the eastern
half of the Nation, with greatest departures in the Ohio and Tennessee Valleys
and Middle Atlantic States. Average temperatures are expected to be above normal
over the Plateau States and near normal in the remainder of the West. Precipita—
tion is predicted to exceed normal along the Gulf Coast and also over the Pacific
Northwest and Northern Plains. Subnormal amounts are anticipated over the
remainder of the Nation, except for near normal in New England, the Great Lakes,
the Central Plains, and southern portions of the Atlantic and Pacific Coasts.
Weather forecast given here is based on the official 30-day "Resume and Outlook"
published twice a month by the Weather Bureau. You can subscribe through the
Superintendent of Documents, Washington, D.C. 20250. Price $4.80 a year, $2.40
a half year.

WEATHER OF THE WEEK ENDING DECEMBER 23
High pressure and low temperatures prevailed over the eastern two-thirds of the
Nation during most of the week. Numerous stations registered their lowest
temperatures of the season. In NORTH CAROLINA, it was one of the coldest weeks
in recent years. The temperature at Tampa, Florida, dropped to 31° Thursday
morning. At International Falls, Minnesota, the maximum Thursday was 14° below
zero. Skies were mostly clear in the arctic air mass that controlled the weather
during the first part of the week. Frequent snow flurries occurred from the
central Great Plains eastward. The arctic air, moving across the relatively
warm waters of the Great Lakes, piled up narrow but deep snow belts along the
eastern shores of the Lakes. Snow at Muskegon, Michigan, accumulated to a depth
of 18 inches by Monday evening, December 16.
Temperatures moderated somewhat as the huge mound of cold air moved eastward.
The temperature at Evansville, Indiana, rose to above freezing Tuesday afternoon
before a second mass of cold air moved down through mid-America. Muskegon,
Michigan, received an additional 6 inches of snow by Tuesday evening and the snow
continued to fall, accumulating to 27 inches by Monday, December 23.
While unseasonably cold weather continued over the vast area from the Rocky
Mountains to the Atlantic Ocean, the weather west of the Rockies was comparatively
mild. Afternoon temperatures in the far southwest exceeded 60° on most afternoons.
Generous rains fell in the extreme northwest where some stations received rain
every day.
Snow fell during the weekend over most of the Rocky Mountains and Great Plains.
Memphis, Tennessee, received more than a foot of snow. The Weather Bureau
issued heavy snow and glaze warnings to help stockmen protect their animals and
for travelers on the highways. Central Arkansas received one of the heaviest
snows of the century. Ice, with some snow mixed, became 2 inches thick at
Vicksburg, Mississippi. The ice in Mississippi caused considerable damage to
timber and to telephone and power lines, and made highway travel extremely
hazardous. The temperature at Memphis, Tennessee, dropped to 13° below zero on
on Tuesday morning, December 24, setting a new alltime record for that station.
The prospects for a white Christmas were certain for most of the eastern two-
thirds of the Nation. For many southern locations, it would be the first white
Christmas in many years.
At the end of the week, gales swept the Washington coast. Rain spread ‘inland
and snow continued over the northern Rockies. The big storm in the east moved
toward New York and New England.
Temperatures for the week averaged slightly above normal over western Washington,
most of Oregon and Nevada, and parts of California. Elsewhere, temperatures
averaged below normal. Most of the area east of the Continental Divide averaged
10° or more below normal. Temperatures averaged 20° or more below normal over
much of the northern and central Great Plains.
Precipitation for the 7-day period ending at midnight Sunday exceeded 1 inch in
the extreme Northwest and over parts of Louisiana and Mississippi, and south-
central Florida, Wide areas from California to New England received less than
0.25 inch during the period. (Summary supplied by U.S. Weather Bureau.)

INTRODUCTION
The explanations that follow will aid in using the 1963 index,
ali
Page numbers underlined represent references to the
"Summary of Insect Conditions in the United States - 1962,"
Page numbers in parentheses represent loss estimates.
The small ° that follows the common name of certain species
in the index indicates that the name is not listed in the
"Common Names of Insects" as approved by the Entomological
Society of America. However, most of these common names
are of foreign species, and the common names used in the
Cooperative Economic Insect Report were taken from liter-
ature sources from a country or countries where the species
occurs,
Complete cross indexing of page references of insects with
common names is not used. The "Scientific Names" should be
used to locate all page references, with the exception of
those insects or groups of insects where the scientific
names were not reported. In these cases, the page reference
will be listed in the "Common Names."
A combination of both common and scientific name of an
insect or pest may not appear on the page referenced,
but one or the other will be present,
A list of corrections for volume 13, not previously pub-
lished, is on pages and
