WEATHER OF THE WEEK ENDING JUNE 27

HIGHLIGHTS: (1) Heat wave North Central and Northeast. (2) Much sunny, dry wea-
ther but local downpours northern plains.

TEMPERATURE: Large persistant high over the Southern Appalachians brought a week
Tong heat wave to the Eastern half of the Nation. Skies were clear, winds were
light and humidity high. Temperatures climbed to the 90's from the central Rockys
to the Atlantic Ocean. Pueblo, Colorado, registered 96° on Friday. Temperatures
reached the 90's on 5 days at Traverse City, Michigan,and on 6 days at Pittsburgh,
Pennsylvania. In much of the Northeast last week was the hottest week of the
year and in Pennsylvania the hottest week since 1964. With stagnant conditions
the lower atmosphere became very hazy reminding one of autumn conditions. In
north central areas only, the hot weather was interrupted by cool Canadian air.
West of the Rockies temperatures were moderate. Except rather cool in the Idaho
area.

Weather continued on page 622.

WHEATGRASS BUGS (Labops spp.)

Labops sp. Adults and Damage to Wheatgrass

Economic Importance: Grass bugs have caused important damage to crested wheatgrass
and other grasses in western areas of the United States in certain years. This is
the fifth consecutive year that severe damage (up to 50 percent) to crested and
intermediate wheatgrass has been observed in Utah. In that State, approximately
58,000 acres of planted grass areas have been severely injured in Garfield and

Kane Counties this year, while large areas of planted grasses have been moderately
injured in Iron County. The insects stunt the growth of wheatgrasses and cause

the leaves to turn yellow or white. In addition, a drop in the yield of seed and
hay may occur. Serious damage to wheat took place at the edges of the fields

when the insects moved from adjacent crested wheatgrass fields in Montana in 1938,
1951 and 1952. In New Mexico, extensive injury to crested wheatgrass in reseeding
areas occurred in 1963 in the Santa Fe National Forest. While L. hesperius is
apparently the principal species found in these outbreaks, Labops Spp., Irbisia spp.
and possibly other plant bugs may be involved.

Distribution: L. hesperius has been recorded in Arizona, Colorado, Idaho, Montana,
Nebraska, New Mexico, Oregon, South Dakota, Utah, Washington and Wyoming. Canadian
records for the species included: Alberta, British Columbia and Yukon Territory.
According to-Slater (1954), eastern records of this species probably should be
referred to as L. hirtus Knight.

Hosts: Crested and intermediate wheatgrasses and other grasses. Wheat, barley and
rye also may be attacked.

Life History and Habits: Owing to the lack of biological studies on Labops, no
definite information iS available. Adults have been collected from early May
through late July. They are generally most abundant in Wyoming in May and June.
Eggs apparently are deposited from late May on to July. As far as known, over-
wintering takes place in the egg stage and there is one generation a year. The
adults are fast moving and difficult to catch.

Description of L. hesperius: Adults are about 6 mm. long and dull black in color
except for a pale streak along the edge of the wing covers and pale spots on the
head. The hairs on the hind tibiae do not obscure the true spines. The eyes are
large, glossy, and project to the sides on narrow stalks. Some females have
abbreviated wings. Fifth-instar nymphs are brownish-yellow in color. The eyes

are set on stalks and the head slopes downward as in the adult. Obvious difference
between L. hesperius and other North American Labops: This is the only species in

- 624 -

which the two side lobes of the head are swollen so as to obscure the middle lobe
when viewed from the side. The projecting eyes are characteristic of the genus.

Guide to Survey for Labops: Look for discoloration in stands of wheatgrasses and
other grasses. If Labops are present, close examination of leaves will show yellow
and white spotting. Spread a clump of grass and look for brownish-yellow, long-
legged nymphs and black adults about 6 mm. long. The large, black eyes of these
bugs are a conspicuous aid in field identification (see illustration). The bugs
may be found also under debris around the plants. Both adults and nymphs can be
collected with a sweep net although the adults move rapidly. If planted fields

are not severely infested, the insects may be more easily found in the margins.

Restoration of Name Chorthippus curtipennis (Harris)
(Orthoptera, Acrididae)

The widespread North American grasshopper, which for many years prior to 1936 was
assigned the name Chorthippus curtipennis (Harris), now has that name restored to
valid usage. In 1936 (Orthoptera of North Dakota, N. D. Tech. Bul. 284, p. 31),
Hebard adopted C. longicornis (Latreille) for this species and regarded curti-
pennis aS a synonym. (Latreille described longicornis from France in 1904, and
Harris described curtipennis from Massachusetts in 1841.) Hebard believed that
longicornis is a Holarctic species found as a native across Europe, northern Asia,
and North America. During the 30 years that the name longicornis has been applied
to United States and Canadian specimens, doubts as to the correctness of that

usage have arisen. First, European entomologists discovered that the type specimen
of longicornis no longer exists and that the description is inadequate to recognize
Latreille’s Species with certainty; as a result, by Opinion 609, International
Commission on Zoological Nomenclature, the name longicornis (Latr.) was suppressed
in 1961 as unrecognizable. Other names are available and in general use for the
several species of Chorthippus: which occur in Europe and Asia. Recently, V. R.
Vickery (Canad. Ent. 96(12):1537-1548, 1964) of Macdonald College, Quebec, has

made a Special study of the genus Chorthippus, entitled "The validity of the name
curtipennis (Harris) for North American Chorthippus."" He has found that the well
known North American species is distinct from its Old World relatives. Hence, he
has restored the use of curtipennis.

This grasshopper, widespread in Canada and occurring across northern United States
and southward along mountains in both East and West, is often encountered during
grasshopper surveys. It was most recently reported from Oregon as longicornis
(USDA Coop. Econ. Ins. Rpt. 16(20):442, 1966).

WEATHER OF THE WEEK ENDING JULY 11

HIGHLIGHTS: (1) Third hot, humid week in Central and East. (2) Mostly dry West,
Showery with highly variable rains East and South Central.

TEMPERATURE: With high barometric pressure persisting, this was the third consecu-
tive hot, humid week from the northern and central Great Plains to the Atlantic
Ocean. In contrast to the scorching heat in other areas, temperatures over the
Pacific Northwest averaged slightly below normal. Polar continental air pushed
into the Northeast early in the week bringing temporary relief from the high tem-
peratures that had prevailed since June 22. Warm moist air poured northward over
mid-America. Temperatures climbed into the 90's from the interior valleys of
California to the Atlantic Ocean and by the weekend, as far north as Montana and
the Dakotas. Some locations in the southwestern deserts and in the central Great
Plains registered 100° or higher on 5 to 7 days. Huron, South Dakota, set a new
alltime record on the 10th when the temperature reached 112°.

Weather continued on page 684.

Weather continued from page 662.

PRECIPITATION: With active fronts and LOW centers remaining north of the Canadian
border, widely scattered afternoon and evening thundershowers were the rule over
the 48 States. Shower amounts were mostly very light from the Rockies westward.
The long dry spell continued in the Southwest as Arizonians waited for the usual
summer Shower period. More frequent and heavier isolated showers occurred in the
Central and East early in the week and over the weekend but precipitation totals
ranged widely and many sections received little or no rain. Drought still threat-
ens in parts of Arkansas and the western ranges deteriorated further. Substantial
rain amounts were welcomed in Kentucky, Indiana, Ohio, and parts of the Northeast
but shower totals were so highly variable that no generalizations as to improve-
ment can be made. General rains are needed but are not very likely at this time
of year. (Summary supplied by Environmental Data Service, ESSA).

WEATHER BUREAU'S 30-DAY OUTLOOK
MID-JULY TO MID-AUGUST

The Weather Bureau's 30-day outlook for mid-July to mid-August calls for tempera-
tures to average above seasonal normals over most of the area lying between the
Continental Divide and the Applachians with greatest departures over the central
Plains. Near to slightly below normal temperatures are anticipated east of the
Appalachians, thereby providing frequent periods of relief from the heat. Below
normal temperatures are also indicated for the Pacific Coast States. This outlook
implies that the current break in the heat over the Plains will be temporary.
Precipitation is expected to total less than normal over the central and southern
Plains. Above normal amounts are predicted west of the Continental Divide, over
the Great Lakes region and along the southeast coast. In unspecified areas about
normal rainfall 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 $5.00 a year.

COTTON

BOLL WEEVIL (Anthonomus grandis) - SOUTH CAROLINA - Old and new weevils in many
cotton fields. Weevil numbers and punctured squares continue to increase in
untreated and seldom treated fields. Where insecticides applied bofore squaring
and continued at recommended 5-day interval, few punctured squares noted. In Pee
Dee area, 50 percent more weevils taken from trap plots this year than at same
time in 1965. (Cott. Ltr., July 11). Adult counts in treated and untreated
cotton plots in Florence area zero. Larval infestations 0.6-2.2 percent in treated
plots, 5-15 percent in untreated plots. Infestations down in untreated fields
probably because of extremely high temperatures and lack of moisture. (Taft et al.,
July 13). TENNESSEE - Square counts averaged 28 percent over regularly infested
portion of cotton-growing area. Some first-generation weevils appearing. Larval
mortality low despite very hot and dry weather. Dry, hot weather may be major
factor in weevil control this season, if continues for some time. Weevils punc-
turing squares as fast as they appear on plants in some instances. No control
started in many of these fields; total crop loss expected if control not started
immediately. (Locke). ALABAMA - Square infestation continues high in northern
area, especially in older cotton where first-generation "hatchouts" occurring.
Counts in central and southern area low to high depending largely on control
efforts. Larvae and pupae in squares on ground killed by extremely hot weather;
75 percent of larvae in one field in southern Lee County dead. Rains and cooler
temperatures occurred in area. Few larvae and pupae dead in squares in some more
northern counties. (McQueen).

GEORGIA - Punctured squares averaged 13 percent in untreated cotton field in
Putnam County; 15 percent in Spalding County. (Beckham). MISSISSIPPI - Punctured

in Pontotoc County. Punctured squares 16 percent in Carroll County; 8-12 percent
in Leflore and Yazoo Counties. (Dinkins). LOUISIANA - Extremely light this year;
might not require controls before August. Punctured squares scarce and live
weevils hard to find. (Tynes, July 11). Single adult found in 131 fields in

FEDERAL-STATE PLANT PROTECTION PROGRAMS

GYPSY MOTH (Porthetria dispar) - MICHIGAN - Larvae collected July 7 in Calhoun
County have been positively determined as this species. A quick survey of area
indicated a local infestation near the northeast corner of Duck Lake in Clarence
Township. Large last-instar larvae have defoliated willow trees in area. Larval
feeding is almost complete and pupation is underway. The 1966 find is in an area
where 5 moths were taken in 3 Separate traps during the 1961 survey season.
Sprays were applied in 1962 and no moths have been taken since. It is surmised
that spray coverage near the lake was inadequate as all precautions were taken to
avoid insecticidal drift in the water. Survey plans call for installation of 500
traps to delimit the infested area. (Turner). RHODE ISLAND - Ovipositing in
Providence County. (Veilleux).

WEATHER OF THE WEEK ENDING JULY 18

HIGHLIGHTS: (1) Hot spell interrupted North Central, Northeast; continues to the
south. (2) Dry most areas but many locally heavy showers. 4

TEMPERATURE: A pattern of very hot weather has persisted in many central and
eastern areas for the last 2 to 4 weeks. The heat was relieved in north central
and northeastern areas by Canadian air which moved south of the Ohio River on
Friday. Temperatures were near 100° in Minnesota and Wisconsin early in the week
but dropped into the 40's late in the week. In the Northeast, temperatures also
dropped into the 40's bringing the coolest weather since June 22. Most of these
areas were hot again by Sunday. Hot weather continued unabated throughout the
South and along the eastern slopes of the Rockies into Montana. Oklahoma City,
Oklahoma, reported 100° or higher every day July 1-18; a sequence which threatens
the record of 22 "century" days set in August 1936. St. Louis with 100° or higher
daily July 9-14 had the longest such spell since 1953. Temperatures at 100° or
higher were common in Georgia while Miles City, Montana, reported 107° on Friday.
In the Southwest, it was normally hot but in the central valley of California and
northward, temperatures averaged as much as 9° below normal; parts of Oregon and
Washington have been cool for 4 weeks.

PRECIPITATION: California, Nevada, and nearby areas, also central Texas, received
no Significant rain. Most other areas had very widely scattered showers affecting
unusually, small areas so that most places were dry. Several Ohio locations re-
eeived 4 to 6 inches and Sandusky reported a record 10.81 inches in about 8 hours
with flash flooding. Heavy local showers also occurred in Alabama and. in many
locations in tHe northern Plains as well as elsewhere. Drought conditions are
intensifying in the Great Basin and in the Northeast where Showers were also
scattered and locally variable. High temperatures are rapidly intensifying the
drought conditions in Oklahoma, Kansas, Missouri, and Arkansas. (Summary supplied

COTTON

BOLL WEEVIL (Anthonomus grandis) - NORTH CAROLINA - Percent punctured squares 76

in 2 untreated Robeson County fields. In Scotland County, 3 fields treated twice
averaged 32 percent and 4 fields treated 3 times averaged 3 percent punctured
squares; 6 fields treated 3-5 times ranged 0-2 percent infestation. Cotton in
these counties squaring freely, few blooms observed. (Mount, July 15). SOUTH
CAROLINA - Buildup continues; first-generation adults now in all sections of State.
Generally, percent Squares punctured continues to rise even though more squares
present on plants. (Sparks, July 18). Infestations increasing slowly in Florence
area with activity of first-generation weevils, but still lower than normal due

to hot, dry weather. Adults 0-3 per 100 squares in treated plots, O-5 in untreated
plots. Larval infestations 0.75-4.8 percent in treated plots, 2.2-40 percent in
untreated plots. (Taft et al., July 20). TENNESSEE - Square counts 19 percent
compared with 28 percent last week. Hibernating weevils about disappeared. Peak

first-generation emergence should occur by July 29. In those areas where some
rain has occurred, situation ideal for further buildup. Infestations heavier in
southeastern portion of cotton-growing area. (Locke). ALABAMA - Survival of

larvae and pupae in squares higher in northern part of State and emergence of
first and second-generation adults medium to high, depending on controls applied
15-20 days earlier. Infestations much higher in area than at same time in 1965
and control efforts more general. Infestation in central and southern counties
light to medium; few counties report high numbers. Hot, dry weather reduced
"hatch out'! of adults and general use of effective controls reduced numbers con-
Siderably. Damaging numbers in all counties including Lauderdale, Limestone,
Madison and Jackson Counties in extreme north. General and widespread infestation
at this time equal to or greater than any time since 1962. In 3 years and part

of this season A. grandis has recovered from extreme weather conditions in winter

of 1962-63. (McQueen).

GEORGIA - Percent punctured squares 1-80 in Colquitt, 1-2 in Worth and 3 in Tift
Counties. (French). Second-generation emergence resulting in very heavy infesta-
tions in Some southern area fields. (Jordan). MISSISSIPPI - Punctured squares
found in 12 of 19 fields in delta counties. Infestation 4.5 percent (maximum 21)
in these 12 fields. (Pfrimmer et al., July 21). Populations at high level
throughout State. Considerable increase noted in Southern delta area. Percent
punctured squares 19-38 in 8 fields in Carroll County; 5-10 in Leflore County;

6-25 in several hundred acres in Yazoo County. Heavy "hatchout' noted in north-
eastern hill section. Punctured squares 60-70 percent in Several counties. In
northern delta region, punctured squares ranged light to heavy. Percent punctured
Squares by county as follows: Marshall 10-20; De Soto 10-30; Tunica 60 in "hot
Spots", with 10-15 in other areas; Tallahatchie 20-30; Panola 60-70 in "hot spots",
with 10-30 in other areas; Coahoma very light with isolated "hot spots" noted in
Some areas; Pontotoc 60-70. (Dinkins). LOUISIANA - Some emergence from Squares
occurred in "hot spots" in older fields first week of July; egg laying more obvious
past week, punctured squares more plentiful in these spots. Heavy emergence ex-
pected last week of July. Infestations higher in southern area than central and
northern areas. (Tynes, July 18). Nine weevils found in 6 of 198 fields in Mad-
ison Parish. Punctures found in 98 fields; percent damaged squares 1-21 per 100
squares; averaged 1.7 percent per 100 squares for 198 fields. (Cleveland et al.,
July 21). ARKANSAS - Present in 62 percent of 5,781 fields compared to 44 percent
last week; 68 or 1.2 percent of infestations at recommended treatment level, com-
pared with 17 fields or 0.3 percent last week. (Barnes, Boyer). OKLAHOMA - Percent
punctured squares 20-30 in cotton adjacent to wooded areas in Grady County. Mod-
erate in Cotton County and light in Bryan County. (Okla. Coop. Sur.). TEXAS -

ALABAMA - Larvae not generally serious except in isolated areas of south and west
sections. (McQueen). MISSISSIPPI - Eggs found in one of 19 fields in delta coun-
ties; injured squares found in 9 fields. Injury averaged 0.9 percent (maximum 2).
Moth flight increased slightly. Moth activity may increase sharply due to recent
rains. (Pfrimmer et al., July 21). H. zea and H. virescens light throughout State;
new generation hatching, however. Continue light in Pontotoc, De Soto, Tunica,
Coahoma, Tallahatchie and Panola Counties. None found in Marshall County. In
Leflore County, eggs 4-8 and larvae 1-2 per 100 terminals. In Yazoo County, eggs

ARIZONA - H. zea scattered and light in Graham, Maricopa and Pinal Counties. No
increase in egg counts noted. (Ariz. Coop. Sur., July 15). H. zea continues light
and spotted; most infestations not economic. (Ariz. Coop. Sur.). CALIFORNIA -
Numbers still high for time of year in Arvin and Wheeler Ridge areas of Kern County.
Larvae not of immediate concern due to earliness of season; however, if numbers
continue high, problem may develop earlier than usual. Due to earliness of crop,
many fields have extremely heavy boll set. (Black, July 14). Populations low in
most of San Joaquin Valley, although few very large larvae still evident. Some
small larvae detected, particularly in parts of Kern County. Moth activity gener-
ally light, although eggs abundant in corn in Shafter and Causelo areas. (Leigh,
Juliyed'5)

- 727 -

Nymphal development and adult migration continue. Increasing in some previously
treated and untreated fields. (Campbell, July 15). Continue of most concern in
Kern County cotton; however, pressure not as high as in previous weeks. No mas-
Sive migrations occurred with recent cutting of alfalfa. Many fields still har-
bor high numbers; nymphs appearing in large numbers in many areas. (Black, July
14). Continue problem in cotton throughout San Joaquin Valley. (Counts per 50
sweeps in Shafter 3-28, Corcoran 3-5, west Fresno County 8-19, Madera County 12-
18; nymphs predominate. Treatment not needed in many fields; infestations have
not built up. (Leigh, July 15). ARIZONA - Continue to cause moderate to heavy
damage to cotton in Pinal, Pima and Maricopa Counties. Increasing in Graham
County. (Ariz. Coop. Sur.).

PLANT BUGS - TENNESSEE - Causing light damage to very small squares over western
area. Control not justified. (Locke). MISSISSIPPI ~ Lygus lineolaris and Psallus
seriatus remain unchanged throughout delta area; no increaSe noted. (Dinkins).

be continual problem throughout season with 180,000 acres of milo under cultiva-
tion. (Campbell, July 15).

LEAFHOPPERS - CALIFORNIA - Continue to increase in some untreated Imperial County
fields; relatively stable with some trend to decrease in other instances. (Camp-
bell, July 15). Abundant in cotton in western Fresno County; however, economic
damage does not appear to be occurring. Cotton growers on east Side of San
Joaquin Valley should be alert to possible economic infestations of Empoasca
fabae. (Leigh, July 15). io ke

- 728 -

infestations very heavy, defoliation occurring. Recommended miticides generally
not giving good results; however, few giving excellent results. Lack of followup
application responsible for most lack of control. Initial applications giving
good control. (Cott. Ltr., July 18). TENNESSEE - Still increasing: extensive
damage expected over western area if controls not applied. Conditions ideal for
further buildup. (Locke). MISSISSIPPI - Continue problem in some fields in delta

erably in Tallahatchie County due to heavy rains; currently light. Heavy in Le-
flore and Issaquena Counties. (Dinkins). MISSOURI - Mostly Tetranychus atlanticus
light in field margins and spots within fields in 21 percent of 623 cotton fields
in southeastern "delta" area. (Jones). CALIFORNIA - Spider mites under control
with few exceptions in Kern County cotton. Controls needed on ends of rows near
dusty roadways in some fields. Plants closing the middle so coverage increasingly
difficult as season progresses. (Black, July 14). Abundant in some San Joaquin
Valley cotton, particularly along field margins and roadways; however, mostly
under control. (Leigh, July 15).

Weather continued from page 718.

PRECIPITATION: Shower activity was rather general except in the Far West where an
area where an area from California to Idaho and westward received little or no
rain. Substantial showers came to eastern Arizona, New Mexico, and Colorado.

From the Rockies eastward to the Atlantic, most areas received moderate to heavy
showers. Though the showers were locally variable as usual, there seemed to be
fewer areas missed than during the previous couple of weeks. A few spots in the
Northeast drought area received generous amounts--4.39 inches at Chester, Massa-
chusetts, is an example. Very dry conditions continued over southeastern Pennsyl-
vania and vicinity. Torrential rains came to other scattered spots. Claiborne,
Alabama, received 5.52 inches in 2 hours while other points in Mississippi and
Alabama received 1 to 2 inches. However no rain has fallen in parts of Kentucky
in 5 to 10 days. Goodland, Kansas, reported only 0.05 inch for the week while
nearby Levant (25 mi. east) received 6.85 inches in 1 day. The gulf coast area
received many heavy showers, e.g., 3.00 inches at Lake Charles, Louisiana, on
Friday; also 1.97 inches at Mobile and 3.70 inches at Jacksonville Beach. (Sum-
mary Supplied by Environmental Data Service, ESSA).

WEATHER BUREAU'S 30-DAY OUTLOOK
AUGUST 1966

The Weather Bureau's 30-day outlook for August calls for temperatures to average
above seasonal normals over the western half of the Nation except for near normal
in the Pacific coastal area. Below normal temperatures are predicted in the upper
and middle Mississippi Valley, the Ohio Valley, the Great Lakes region and New
England. Below normal temperatures are also expected for the south Atlantic
coast. In unspecified areas near normal temperatures are in prospect. Rainfall
is expected to exceed normal from the Great Lakes eastward to New England and
also over much of the Southeast. The central and southern Plateau regions in the
West are also expected to receive above normal rainfall. Subnormal totals are
indicated for the northern and central Plains and near normal precipitation for
unspecified areas.

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 $5.00 a year.

A ROOT MEALYBUG (Geococcus coffeae Green)

Introduction: The insect, described from specimens collected on roots of coffee
tree (Coffea liberica) from Dutch Guiana (Green, 1933), was first found in Florida
in 1958 on roots of Dieffenbachia sp. and Philodendron selloum, by H. M. Van Pelt.
These foliage plants were commercially grown in a greenhouse in Apopka. Determi-
nation made by H. Morrison showed this to be a new record for Continental United
States. In 1958, a special survey of greenhouses in Florida resulted in positive
finds at Apopka, Altamonte Springs, Lockhart, Oviedo, and Zellwood. Attempts were
made to eradicate each infestation by insecticides. In September 1965, a new in-
festation was found by C. O. Youtsey on the roots of both container-grown citrus
in a Winter Haven greenhouse and those of Chinese boxorange adjacent to a green-
house. Infestation of Chinese boxorange shows that G. coffeae is capable of
attacking plants outside greenhouses in Florida. Eradication of the mealybug at
Winter Haven was underway in December 1965.

Economic Importance: This ground-inhabiting species feeds on roots of plants.

While it is known as an economic pest in some cacao and coffee-producing regions,
its economic potential in Florida is unknown, As citrus is a host, every precau-
tion is being taken to eradicate G. coffeae in Florida.

Hosts: Aglaonema, Caladium, Canna, Chamaedorea, Citrus, Codiaeum, Coffea, Cyperus,

Distribution: Brazil, Canal Zone, Ceylon, Colombia, Costa Rica, Cuba, Dominican
Republic, Dutch Guiana, Gold Coast, Guatemala, Honduras, India, Nigeria, Palau,
Panama, Peru, Philippines, Uganda, El Salvador, Zanzibar and U.S.A. (Florida,
Hawaii and Puerto Rico).

General Distribution of Geococcus coffeae

(Homoptera Pseudococcidae)

- 768 -

Description: Adult female Snow white, elongate-oval 2-2.5 mm. in length. Anal
Lobes red-brown with prominent, upturned, chitonized, blunt anal hook at tip of
each lobe (see illustration). Much smaller pair of downward curved, chitonized,
median dorsal hooks appear to occur on last abdominal segment (see illustration).
The prominent hooks are key characters for separating G. coffeae from other sub-
terranean species in Florida. one

WEATHER OF THE WEEK ENDING AUGUST 8
HIGHLIGHTS: (1) Violent frontal weather. (2) Cool East; hot West.

The week began and ended with a strong cold front pushing southeastward from the
Canadian border. Most of the Country bore the brunt of intense shower activity

as these frontal zones moved toward the gulf. High winds, hail, heavy rain, and
funnel clouds accompanied localized thunderstorms from the Dakotas southward.
Flash flooding was common along the eastern front ranges of Colorado. On Wednes-
day and Thursday range and forest fires started by lightning destroyed over 15,000
acres in the Garden Valley district of Idaho. By Monday the largest fires were
still out of control in the Boise National Forest. Much of the Southeast received

heavy rain when the first front became stationary from Texas through South Carolina.

Weather continued on page 782.

Weather continued from page 770.

Behind the fronts flowed Canadian air. As this cool, dry air moved southward,
temperatures plunged and several localities experienced record low temperatures.
It was the coolest week since mid-June in most areas east of the Rockies. Average
thermometer readings were more than 6° below normal in the southern Great Lakes
region and in the Middle Atlantic States. The weather was more typical of autumn
than of summer. The western part of the Country, however, was hot. Temperatures
climbed to at least 100° for 7 consecutive days in the interior valleys of Cali-
fornia, and the hot, dry conditions continued in Nevada. Positive departures

from normal of 7° were recorded in Arizona and over 5° in Oregon.

The weekly precipitation pattern reflects the spotty Shower activity in the East
and the continued dryness in the West. The Southeast received generally wide-
spread showers as a result of the stationary front, but the drought in the
Northeast was not relieved. Southern New England reported its driest week in
more than a month. The area from Evansville, Indiana, to Cincinnati, Ohio,
remained arid while some areas to the west of this region received over 4 inches.

BOLL SLICING: A SCOUTING METHOD FOR BOLL WEEVIL
(as used in Arkansas)

Charles Lincoln and W. P. Boyer

For some time workers in Arkansas have sliced bolls, in varied numbers and by

different methods of selection, to evaluate damage by boll weevil (Anthonomus

grandis). Experience showed that weevil feeding on bolls is manifested by two
types of effect within the boll. This led to classification of bolls as A, B,
and C:

A. Damaged by boll weevil as shown by watery, yellowish, or darkened
areas in the lint and seed.

B. Punctured by boll weevil as shown by a blister or puncture on the
inner wall of the carpel, but not damaged.

C. Clean - no boll weevil feeding.

In 1963, several cotton insect scouts sliced bolls according to the following
instructions: Begin sampling three weeks after blooming starts and sample weekly.
After completing the first and third point samples of 50 squares (Arkansas Agri-
culture Experiment Station Bulletin 666), make the boll slicing count as follows:
Measure 6.5 feet of row. Pick all bolls half grown or larger but tender enough

to slice readily (9-21 days of age). Slice all candidate bolls and class them A,
B, or C. This gives a one thousandth-acre sample. Quantitative data on punctured
squares were obtained by the point-sample method of scouting (Arkansas Agriculture
Experiment Station Bulletin 666).

Results of the last four weeks that squares were available in 1963 are shown in
the following table:

Last Four Weeks Squares Were Available, 1963
Punctured squares per acre, thousands 10 10 15 7
A and B bolls per acre, thousands 4 6 12 14

Total damaged squares and bolls, per
acre, thousands 14 16 27 21

This shows transference of attention from squares to bolls. The apparent decline
in weevil population observed in point-sample counting reflects this transference.

Most fields received insecticide treatment. Scanning results do not indicate any
shift to or away from boll feeding associated with level of insecticide usage.

Comment: The publication of this method in CEIR would, no doubt, result in other
workers checking it to determine its validity. This might lead to the development
of an acceptable method.

The criteria used by Dr. Lincoln and Mr. Boyer could probably be used satisfac-
torily in areas where only the boll weevil occurs. In an area also infested by
the pink bollworm the same type boll damage symptoms described for the boll weevil
in item B could be caused by the pink bollworm. Also, lygus bug and stink bug
damage to bolls could be similar to that described for the weevil in categories
A and B. Therefore, when the general infested areas of the boll weevil are con-
sidered, it may be difficult to separate boll weevil damage to bolls from that
caused by pink bollworms, stink bugs, lygus bugs and possibly other insects.
(S. E. Jones).

Survey of Forage Crop Insects in Massachusetts in 1966

F. R. Shaw, R. A. Callahan and M. C. Miller

As one phase of the investigations of forage crop insects in Massachusetts,
extensive collections were made in Berkshire, Hampden and Hampshire Counties with
supplementary collections in Franklin, Worcester, Plymouth and Bristol Counties.

In 1966, the most abundant single species was alfalfa weevil (Hypera postica).

A maximum of 2,573 per 100 sweeps was obtained, this being markedly lower than

the 4,100 per 100 sweeps collected the previous year. Untreated fields had moderate
to severe damage, with many exhibiting a characteristic frosted appearance. Many

of the fields were cut late which added to the damage done by the weevil larvae.

The first adult weevil was taken in Amherst on April 22, the first larvae were

taken on May 4.

Pea aphid (Acyrthosiphon pisum) was more numerous than it had been last year,
comprising 8.8 percent of the total; although slightly increasing it still has
not attained a population of 45 to 60 percent of all insects as it had in earlier
surveys. Beneficial insects, including lady beetles, damsel bugs, lacewings and
syrphids, were less abundant than in 1965, comprising 0.48 percent of the total
versus 0.58 percent last year. Plant bugs remained approximately equal to last
year's count, comprising 3.7 percent of insects collected. Leafhoppers at 0.8
percent of the total showed a Sharp decrease from 3.81 percent the previous year.

A summary of the results of the survey is presented in the following table. This
report is based on collections of 22,182 insects taken from April 22 through

June 24. Sampling was done by taking 100 sweeps with a 15-inch net in each field
at approximately weekly intervals.

WEATHER BUREAU'S 30-DAY OUTLOOK
MID-AUGUST TO MID-SEPTEMBER

The Weather Bureau's 30-day outlook for mid-August to mid-September calls for
temperatures to average below seasonal normals over the Great Plains and the Mid-
west. Above normal averages are indicated for areas west of the Continental
Divide and also for the Northeast. Elsewhere near normal temperatures are in
prospect. Rainfall is expected to exceed normal over the eastern half of the
Nation except for near normal amounts over the Upper Mississippi Valley and along
the Gulf Coast. Over the western half, above normal precipitation is called for
over most of the Central and Southern Plains while subnormal totals are indicated
for the Northern Plains, the Northwest and the Pacific Coast. In unspecified
areas near normal 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 $5.00 a year.

WEATHER OF THE WEEK ENDING AUGUST 15, 1966
HIGHLIGHTS: (1) Torrential rains Nebraska, Texas, Arkansas. (2) Cool Midwest.

The town of Fullerton, Nebraska was submerged under as much as 17 feet of water
Saturday after 14 inches of rain fell in 24 hours. People were stranded in tree
tops, dams and levees crumbled, the water main broke, and civil devense work was
carried out in boats. The flood waters of the Loup River and its tributaries
necessitated the evacuation of the residents of Fullerton as well as Columbus.
Although the results were not so disastrous as in Fullerton, other areas of
Nebraska also received heavy rain. By 4 p.m. Friday, Albion recorded 11 inches;
Wolback, 9; Ord and Scotia, 6. A foot of rain also fell in southwest Texas on
Friday and Saturday. Smaller rivers and streams were at their highest water
levels in history, and flooding was severe along the Nueces and Frio Rivers. On
Thursday extreme southeast Texas was unundated as 10 inches fell from Houston to
the Louisiana border causing serious flooding. Almost 7 inches fell on Saturday
morning in east central and southwest Arkansas. With only half the month finished,
Little Rock has already broken its August precipitation record. So far 11.7
inches have fallen, eclipsing the 1888 monthly total of 11.1 inches. Elsewhere
in the South, precipitation was heavy in the central Carolinas and along the Gulf
Coast. Welcomed widespread rain fell in the parched Northeast and Ohio Valley,
but the serious drought conditions persisted in the West. It was the wettest
week in over 1 month in West Virginia, 2.5 months in Kentucky and 3.5 months in
Pennsylvania.

On Thursday winds reached a devastating speed of 156 m.p.h. during a severe thun-
dershower at Linden, New Jersey, and winds blew out windows of homes on Long
Island. Gusts up to 70 m.p.h. accompanied several of the storms that swept across
the Nation during the week.

A series of continental polar air masses caused temperatures to be below normal
from the Rockies to the Appalachians. For the second straight week the cool
weather in the Midwest was more typical of autumn than of summer. The Southwest,
however, remained hot. Near normal temperatures prevailed in the rest of the
Country. (Summary supplied by Environmental Data Service, ESSA).

STATUS OF PEAR SAWFLY IN THE UNITED STATES

The presence of pear sawfly (Hoplocampa brevis) in Ontario, Canada, was confirmed
in 1965. This was the first report of the European species in North America,
Taxonomic study of Canadian material led to a review of specimens of this group of
sawflies in the United States National Museum collection. The study revealed that
H. brevis had been collected from Orange County, New York, in 1953. A definite
determination at the time had not been possible due to taxonomic difficulties in
the group and the poor state of the specimens.

Plant Pest Control Division and cooperators in the Northeastern States conducted

a detection survey for the pest during the spring of 1966 in order to determine if
it was still established in Orange County, New York, and if it occurred in addi-
tional areas. The map below shows where the insect was found in this survey.
Presence of H. brevis was confirmed in 5 counties in New York, 3 in Pennsylvania,
5 in Connecticut and one in Rhode Island.

As far as can be determined, the sawfly has not developed to economic significance
in any area where it has been found in the U. S. This fact, together with its
widespread distribution in the Northeast, would indicate that further organized
Federal and State action against the pest is not indicated at this time. The
pest should be kept under surveillance, however, as it has been known to develop
into sporadic outbreaks in Europe. Alertness for its presence in the major pear-
producing areas, particularly in the West, should be maintained. Cooperators

are encouraged to report the presence of H. brevis and its activity to Survey and
Detection Operations, Plant Pest Control Division, in order that a current file
may be maintained on this introduced species. (PPC).

NEOTROPICAL CORN BORER (Zeadiatraea lineolata (Walker))

Economic Importance - Small larvae skeletonize patches of leaves of young corn,
whereas older ones tunnel the stalks and sometimes the ears. Damaged stalks may
be broken by the wind or cultivation. Lodging and loss of ears often result in
reduction in yield. The species occaSionally is a pest of corn in Venezuela.
There is little in available literature on the economic importance of this pest.

Distribution - Bahamas, British Guiana, Colombia, Costa Rica, Cuba, Guatemala,
Mexico, Nassau, Nicaragua, Panama, Salvador, Trinidad, Venezuela. United States:
Texas. Collections of this species were made by P. T. Riherd as early as Septem-
ber 23, 1954. Additional collections included larvae reared from corn in August
1964. Determinations were made by P. T. Riherd and confirmed by R. W. Hodges.
According to Dr. Hodges, earlier records of the species in the United States were
based on color pattern and are open to doubt.

Hosts - Corn, Guatemala grass (Tripsacum laxum) and teosinte. Although attacks
on Sugarcane have been recorded in literature, H. E. Box states that these are
rare and accidental.

Biology and Habits - Eggs are deposited on the upper leaves of corn or later on
young ears in irregular clusters. When in clusters, the eggs overlap like scales.
A female may deposit up to 448 eggs. Two days following oviposition, eggs have
2-3 broad, irregular, transverse bands which are bright red. Hatching occurs in
about 5 days. In young corn small larvae skeletonize patches of the leaf but

soon burrow into the terminal buds often reaching the tassel and may destroy a

few of the male flowers. When the leaves of the terminal bud unfold, characteris-
tic, transverse rows of tiny holes appear. Older larvae sometimes tunnel the ears
but usually follow the main stem and avoid the ear. The holes made by the larvae
are conspicuous by the masses of frass which they push through. The larval stage
lasts about 22-48 days in growing corn. Pupation occurs in a chamber at the end
of the burrow. This stage lasts 9-13 days.

The resting stage, in which some of the larvae survive the dry season when the
living host plant is absent, is one way to distinguish this species from sugarcane
borer (Diatraea saccharalis). As the latter has many alternate hosts, it does not
enter a resting stage. Larvae, over half grown, enter dry stalks where they remain
throughout the dry season. During this time, they lose their spots, become butter
yellow and may molt once or twice. Pupation occurs after rains soak the stalks.
Adult females live only 3-5 days and males about 3 days. Although these are sel-
dom seen in the field, they may be taken at lights and in light traps. Females
apparently deposit a single batch of eggs. The entire cycle may take place in

7-9 weeks.

Description - Adult - Forewing ground color light straw yellow; veins lined with
brown, the interlines absent or faint and not well defined; discal dot variable

in size and distinctness; both this and terminal dots brown, of a uniform color
with the vein linings. Hind wing soiled white in the male, white in the female.
Front with a pointed tubercle. Hind tibia of male without hair tuft but abdomen
on male with hair tufts on second segment. Wing expanse of male 20-31 mm.; female
26-40 mm. Larva - Structural, diagnostic characters are not available to separate
this species from southwestern corn borer (Zeadiatraea grandiosella). Larvae and
associated adults are needed to identify this stage.

WEATHER OF THE WEEK ENDING AUGUST 22
HIGHLIGHT: Typical Summer weather.

TEMPERATURE: A Slight southerly shift of the jet stream brought cold, Canadian
air into the northern Great Plains. As a result, the weekly temperature averages
in this part of the Country were much below normal. Negative anomalies of more
than 9° were common in South Dakota. The shift of the jet stream also caused
pronounced ridging along both coasts. The southerly flow that accompanied these
high pressure systems resulted in unusually warm temperatures in the West and
most of the East. The low humidities, the aridity, and the heat in Oregon and
Utah greatly increased the danger of widespread forest fires, and the old record
number of 48 summer days of 90°+ temperatures in Harrisburg, Pennsylvania, was
equalled on Friday.

Weather continued on page 848.

Republic of Mexico as follows: Territorio sur de Baja California 27, Sonora 99,
Chihuahua 123, Coahuila 1, Nuevo Leon 7, Tamaulipas 28. Total of 595 cases '
reported from Mexico south of Barrier Zone. Barrier Zone is area where eradica-
tion operations underway to prevent establishment of self-sustaining population
in U. 8. Sterile screw-worm flies released: Texas 3,706,250, New Mexico
5,328,000, Arizona 13,548,000, Mexico 94,360,000. (Anim. Health Div.).

Weather continued from page 826.

PRECIPITATION: Most of the weekly rainfall was confined to the eastern half of
the Nation. The heaviest totals were recorded in a north-south oriented line

from Arkansas through Minnesota, but spotty showers also brought locally heavy
amounts to the’ Southeast and lower Great Lakes region. The meteorological drought
areas of the East and West were generally dry, but the light rain in the Northeast
was sufficient to sustain some crops. Conditions in Utah, Nevada, and Oregon,
however, remain serious. The usual summer thundershowers, windstorms, tornadoes,
funnel clouds, and cloudbursts spread across the Country during the week. Damage
was slight except during a windstorm on Tuesday in New York. Losses in excess of
$140,000 were incurred at the Canastota Airport when a hangar was tossed 100 yards,
7 planes were completely destroyed, and 3 other aircraft were heavily damaged.

Preparation of Notes for Cooperative Economic Insect Report

Requests have been received relative to the type of information desired for the
Cooperative Economic Insect Report and suggestions made for revision in the format.

The report will be reorganized on a principal crop basis. This will simplify
present format and make the material more accessible and useful. It is hoped
this approach will also stimulate greater participation by pointing out lack of
reporting on individual crop problems. Efforts will be made to evaluate and pre-
sent the information in ways to make it more useful in insect control.

Forecasting statements will be developed wherever field reports support such ac—
tion. Reporters are encouraged to include this vitally important information in
their notes. Emphasis of the Cooperative Economic Insect Report will be on the
important insect problems of a regional nature, notes on routine insect occurrence
will be kept to a minimum. Routine notes submitted on common insects will be
added to the National insect files as warranted, however.

The following guidelines are suggested for preparation of notes. It is realized
that all of the information outlined will not be available in each situation, but
give the following information when possible.

1. Common (if available) and scientific name of species involved. Stages
of insect involved. (If a taxonomic problem exists, it should be
noted).

2. Location (definite, recognized area within state, such as region,
county or town), date, name of observer or reporter. If note is for
period other than current reporting period, give date of observation.

3. Host involved, scope and extent of infestation in number of counties,
acres, trees, animals, etc. Also stage of host.

4. Quantitative evaluation of infestation according to recognized survey
methods. Where such methods are not available, give numerical data
such as number per linear foot, per plant, per sweep or per animal.
These data should be based on a representative sampling. An adjectival
rating should be accompanied by a numerical rating.

5. Estimation of extent of injury or damage.

6. Comparisons with previous infestations, outlook or predictions for
future infestations, unusual influences.

7. Status of natural or applied control.

8. When reporting new State, United States, or North America records, in-
clude the above information insofar as applicable, as well as name of
taxonomist making determination.

Examples of notes including these data are as follows:

EUROPEAN RED MITE (Panonychus ulmi) - Egg populations have reached point
where protective sprays are warranted in 10 percent of apple orchards in
Knox County. Counts on June 30 Showed 0 to 4.8 live mites per leaf and
0 to 37.6 eggs per leaf. Further increase and spread expected with
continued favorable weather. (Jackson, July 2).

EUROPEAN CORN BORER (Ostrinia nubilalis) - Oviposition and hatch practi-

cally complete in central counties. Fifty egg masses per 100 stalks in
northwest area. In southern counties, all corn 35 inches or taller, 70

to 100 percent infested with 2 to 22 larvae per stalk. Larvae from first
to third instar. (Smith). Coop. Econ. Ins. Rpt. 16(7):126

WEATHER OF THE WEEK ENDING AUGUST 29
HIGHLIGHTS: (1) Cold Central; hot West. (2) Heavy rains Texas and New Mexico.

TEMPERATURE: A continental polar air mass brought pleasant, cool, dry weather to
moSt of the Nation east of the Rockies. Hot, humid conditions ended as low tem-
perature records fell eastward from the Dakotas to Texas. The reading of 38° in
Rapid City, South Dakota, on Monday morning and the maximum of 66° in Midland,
Texas, on Wednesday set new August records. The week was the coolest since mid-June
in Kentucky. It was also the 6th consecutive week of below normal temperatures in
Iowa and the 4th consecutive cool week in Nebraska. Negative anomalies greater
than 3° were common throughout the central part of the Country; 15° departures
were reported in the Texas Panhandle. In the extreme Southwest and the northern
Rockies the 6-week hot, dry spell continued unabated. The 97° recorded at Helena,
Montana, on Friday was the highest ever this late in the summer season at this
city. The desert drought areas did not receive relief from the searing weather,
and potential fire hazard remains high.

PRECIPITATION: Heavy rains in Texas and southeastern New Mexico during the early
part of the week caused extensive damage. Dell City, Texas, was 90 percent flooded
and property and crop damage was in excess of $4 million: Over $1 million worth
of damage was reported in the Carlsbad area of New Mexico. The extensive flooding

Weather of the week continued on page 871.

closed most highways and disrupted communications. Beneficial rains fell in most
of the East. Moderate amounts were reported across central New York and New
gland and along the western Appalachians. Heavier Showers produced more than 2
mches along the Carolina coasts and central Florida. The dominance of the dry,
high pressure system over the Central States caused the remainder of the Country
to receive only slight precipitation. (Summary supplied by Environmental Data

WEATHER BUREAU'S 30-DAY OUTLOOK
SEPTEMBER 1966

The Weather Bureau's 30-day outlook for September calls for temperatures to aver-—
age above seasonal normals over the Rocky Mountains, the Northern and Central
Plains and the northern Mississippi Valley. Subnormal temperatures are indicated
for the North Atlantic States as well as most of the South Atlantic States and the
southern half of Texas. Elsewhere near normal temperatures are in prospect.

Precipitation is expected to exceed normal along the North Pacific Coast and also
over the Southern Rockies, the Southern Plains and along the Gulf and South Atlan-
tic Coasts. Subnormal totals are called for from the Northern Plains eastward
through the Midwest to the Middle and North Atlantic Coast States. In unspecified
areas near normal precipitation is expected.

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 $5.00 a year.

Weather continued from page 874.

WEATHER OF THE WEEK ENDING SEPTEMBER 5

HIGHLIGHTS: (1) Hot, humid conditions continue East. (2) Cool, crisp air invades
West.

The week's weather newS was dominated by-a persistent warm, humid air mass over
the East and by a cool, dry air mass over the West. The former system, present
for 2 weeks, resulted in generally mild and hazy conditions from the Midwest to
the Atlantic. There was a dearth of precipitation associated with this system.
(The driest week of the Summer Season was reported in Virginia). The stability
of the anticyclone trapped pollutants in most industrial areas. Under the influ-
ence of the light, southerly winds, temperatures rose and positive departures
from normal of more than 6° were common throughout the Middle Atlantic and Great
Lakes States.

In contrast to the languid weather in the East was the crisp, cool air in the West.
Generally dry, sunny, and very pleasant autumn conditions prevailed. Temperatures
averaged about 3° below normal, and rainfall was Slight. The dryness in the
desert drought areas continued, eSpecially in Nevada. Since January 1, 1966, Reno
and Carson City, Nevada have received only 13 percent of normal precipitation, and
the southeastern part of the State has received only 25 percent of normal rainfall.
During the latter part of the week, this cool, Canadian air mass gradually spread
eastward ending the hot, humid weather in the Midwest and East.

Most of the precipitation during the week was associated with the instability at
the boundary between the cool, dry, western air and the hot, humid, eastern air.
The more violent Showers and thundershowers occurred during the weekend. Locally
heavy rain was reported in Texas and Oklahoma, along the Mississippi Valley, and
in central New York and New England. It was the fifth consecutive week that gen-
eral showers have occurred in Texas. (Summary supplied by Environmental Data
Service, ESSA).

Estimates of Damage by the European Corn Borer
to Grain Corn in the United States in 1965

Compiled in Survey and Detection Operations, PPC, ARS

The loss to grain corn, attributed to the European corn borer (Ostrinia nubilalis)
in 1965 is estimated to be approximately 54,318,100 bushels in I6 corn-producing
States. In these States, the loss was 1.43 percent of the production. This loss
is approximately 1.24 percent of the total national crop estimated at 4,171,100,000
bushels. 1/ The value of the loss, based on the season average prices received by
farmers for corn 2/, is $59,374,160. These loss estimates are only for the States

shown in Table 1, and are based on the counties or districts surveyed during the
fall of 1965 within these States. 3/

Table 1 is a composite of State and Federal estimates. These estimates were pre-
pared by using production data 1/, and prices received 2/, released by the Sta-
tistical Reporting Service. The basis for the loss estimates was determined by
the survey of European corn borer populations during the fall of 1965. 3/ The in-
dex of 3 percent loss per borer per plant was used to compute the loss in bushels.

Estimated loss to grain corn for the past 14 years in States where the fall abun-
dance survey was conducted are as follows:

1965 54,318,100 Bushels $ 59,374,160

WEATHER OF THE WEEK ENDING SEPTEMBER 12

HIGHLIGHTS: 1. Drought intensifies Great Basin, Midwest, and Northeast. 2. Sunny,
pleasant most of Nation.

TEMPERATURE: Persistent high pressure dominated the weather over most of the
Nation during the week. Skies were bright and sunny; winds, calm or light; morning
temperatures, cool and invigorating; afternoon temperatures delightfully mild.
This weather is typical at the end of summer and the beginning of autumn. Daily
maximums ranged from the 60's and 70's from the Great Lakes and Northeast to near
90° along the gulf coast. Portions of the northern and central Great Plains re-
gistered 90° temperatures on several afternoons late in the week. Much of Montana
averaged 10° warmer than normal. In contrast, most of the area south of a line
from New Mexico to Lower Michigan averaged cooler than normal. Minimum tempera-—
tures ranged from frosty 30's over parts of the Great Basin, the northern and
central Rocky Mountains and northern Appalachians to soothing 70's along the Mexi-
can border and gulf coast. Bondurant, Wyoming, registered 23° on one morning, one
of the coolest temperatures in the Nation.

PRECIPITATION: Little rain fell over most of the Nation. The drought intensified
in the Great Basin, the Midwest, and Northeast. In western Nevada, the moisture
deficit became the most Serious in history. It was the driest week of the summer
in Ohio. Many stations in Pennsylvania and the eastern slope of Appalachians from
North Carolina to southern New England received no rain or only sparse precipita-—
tion. There were a few exceptions to the generally dry weather. The Far North-
west received light rains late in the week. General showers fell in Texas for the
sixth consecutive week. Galveston's weekly total was 7.36 inches. Generous rains
fell over the Florida Peninsula and weekend showers occurred from Arkansas to
southern Indiana. (Summary supplied by Environmental Data Service, ESSA).

WEATHER BUREAU'S 30-DAY OUTLOOK
MID-SEPTEMBER TO MID-OCTOBER

The Weather Bureau's 30-day outlook for mid-September to mid-October calls for

temperatures to average below seasonal normals over the eastern third of the Nation
and also in the Southern Plains. Above normal temperatures are indicated from the
Northern and Central Plains westward across the Rockies to the North and Central
Pacific Coast as well as along the South Pacific Coast. Elsewhere near normal

temperatures are in prospect. Precipitation is expected to exceed normal over the
Southwest, the Central Plains and along the middle and north Atlantic Coast. Sub-
‘normal precipitation is called for from the Gulf Coast region northward across the
Ohio Valley to the Great Lakes region. In unspecified regions near normal precip-
itation 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 $5.00 a year.

WEATHER OF THE WEEK ENDING SEPTEMBER 19

HIGHLIGHTS: (1) Cool most of Nation. (2) Beneficial rains in several drought
areas.

TEMPERATURE: Temperatures averaged below normal over most of the Nation. Some
large areaS in western Nevada, the central Great Plains, the southern Appalachians,
and along the middle Atlantic coast averaged 6° or more below normal. A cold front
moved southward across the central and eastern portions of the Country bringing a
quick change to cooler weather. Temperatures dropped to below freezing at scat-—
tered localities from the western edge of the northern Great Plains eastward to

New England. In the central cranberry bogs of Wisconsin the temperature fell to
19°. Scattered frost occurred in many low spots, but caused little damage to
crops. In contrast to the cool weather prevailing over most of the Nation, two
areas averaged warmer than normal. Temperatures averaged slightly above normal
from northeastern Minnesota to Upper Michigan and 4° to 6° above normal over north-
western Montana. The coldest temperatures of record for so early in the season
occurred at scattered stations from the Great Lakes to New England on the 15th and
16th and the warmest temperatures of record for so late in the season were recorded
in central Montana where, on Sunday, the mercury climbed to 90° or higher.

PRECIPITATION: Showers and thunderstorms occurred over widely scattered parts of
the Nation early in the week. Southern Arizona received an inch or more of rain
early in the week. Four to more than six inches fell on Monday and Tuesday from
central Alabama to the Florida Panhandle with lesser amounts recorded in nearby
areas. . The weekend brought the first general rains in several months to Nevada
and a few stations received more than 1 inch in 24 hours. For the 7th week, Texas
reported general showers over the State. An east Coast storm at midweek dropped
uniformly heavy rains over the heart of the Northeast Drought Area. Rain started
over the southern Appalachians on Tuesday and moved slowly northeastward on Wed-
nesday and Thursday. Amounts totaled 3 to 8 inches over the area extending from
the Virginia mountains to central New Jersey and more than 10 inches fell near
Thurmont, Maryland. Rains were in the 1-to 2-inch range along the immediate coast

while less than 1 inch fell northwest of the mountains. In central New Jersey
this was the heaviest weekly rainfall since July 1965; South Mountain, Pennsylvania,
reported the heaviest rainfall since November 1952. In Washington, D. C. the

immediate threat of a water shortage ended abruptly. The rain fell steadily with
little runoff and soil penetrations of 10 to 18 inches were reported. The first
snow of the season fell in the northern mountains of Nevada and Utah. Snow also
fell at elevations above 7,000 feet in Colorado and at the higher elevations in
Montana and Wyoming. (Summary supplied by Environmental Data Service, ESSA).

EUROPEAN CRANE FLY (Tipula paludosa Meigen)

Economic Importance - This tipulid, considered the most damaging of the crane
flies of northern Europe, is a serious pest of grains and sod grasses. It also
attacks many other crops. Larvae feed on roots and other tender plant parts.
Heavy infestations may develop. An estimated 2.75 million larvae per acre have
been found in lowland pastures in Scotland. An average of 24.8 larvae per square
foot was found locally on lawn in Newfoundland. Infested grass areas become thin
and yellowish. The stand in germinating grain fields may be severely affected.

In Canada, where the European crane fly was identified for the first time in 1955,
the species attacks lawns, grasses, and crucifers. Severe damage to lawns in
North Surrey (a suburb of Vancouver), British Columbia, has been reported.

Distribution - Canada: Newfoundland, Nova Scotia, British Columbia. Denmark,
France, Germany, Great Britain, Norway, Poland, Spain, Sweden, Switzerland, USSR
(European).

United States: Washington (A single male taken in light trap at Blaine on Sep-
tember 14, 1966, additional male collected on September 23, 1966).

Hosts - Barley, oats, wheat, rye and other grasses; turnip, strawberry, peas,
corn, tobacco.

Biology and Habits - Adults, which appear from the latter part of June through
September, usually fly during the evening, but may be active also in the morning.
Copulation occurs shortly after emergence and lasts for an hour or more. Females
Oviposit very soon after mating. The eggs are usually pushed into the soil;
however, females have been observed ejecting eggs while suspended from plants.

Egg laying may take place at several sites. Each female may deposit 250-500 eggs.
Incubation takes two weeks. Young larvae normally feed on decomposed vegetable
debris but readily turn to living plants when the soil is low in organic content.
The length of larval stage may vary but usually lasts about 9 months. Overwinter-
ing takes place in or on the soil surface in which the larva makes irregular
galleries. The larva is resistant to cold and becomes active when the tempera-
ture rises, but is extremely susceptible to drought and high temperatures. The
older larvae migrate at night and feed heavily on host plants. Pupation takes
place near the end of May and emergence occurs in about 3 weeks. In France,

there is only one generation a year.

Description - Adult - Clear brownish. Head elongated in form of a snout, antenna
brown, with 14-15 segments, the first two yellow. In some females the third and
fourth segments also may be yellow. Sides of thorax, scutellum and postscutellum
covered with a grayish frosting. Wings straight, elongated and have a milky tinge,
brownish along length of anterior margin. Female with abdomen longer than wings.
The species is difficult to distinguish from other tipulids, particularly females.
Males may be identified by genitalia. Length of male 16-18 mm., female 19-25 mm.

Larva - Young larva pinkish white and thin with a rather large head. Length
about 3 mm. Older larva cylindrical, grayish, with a black head, and two strong
mandibles. Legless, posterior part of abdomen with 6 membranous protuberances
between which are two large black and rounded breathing pores. Length 35-40 mm.

Surveys for Heliothis Moths in Arkansas—
W. P. Boyer, Charles Lincoln and J. R. Phillips

The use of sugar baits has been developed as a survey method to determine field
populations of Heliothis moths in Arkansas. Light traps placed in forestry towers
are being used to Study possible migration of moths.

Sugar baits were used by Burdette (1932) and by Ditman and Cory (1933) to test the
response of moths to sugar solutions. Ditman and Cory (1936) tested several in-
secticides as a control measure for moths. In early work some 30 years ago many
moths were killed, but effective control was not obtained.

In Arkansas the possibilities of sugar baits for survey and control purposes are
being reexamined. The survey aspect only is covered in this report.

Limited work in 1961 and 1962 showed that moths would respond to a sweet spray on
cotton plants. In 1963 methods were developed and standardized. Survey by this
method was expanded in 1964 and again in 1965. Crops sprayed have been cotton,
corn, soybeans and combine-type grain sorghum.

Sugar spray is applied to each 50th row in a field. Row length determines the
number of rows selected. Total row length sprayed generally amounts to one-half
to one mile.

The sugar spray is applied around 6:00 p.m. using a compressed air sprayer at
walking speed with one nozzle held six inches to one foot above the plants. Pres-
sure is kept relatively low to give large droplets; however, droplets can be too
large resulting in the spray running off the plants. After comparing sugar con-
centrations of 0.75, 1.5 and 3 pounds per gallon, 1.5 pounds per gallon was chosen
as a Standard.

Baited rows or "sugar lines" are checked soon after dark at slow walking speed,
using a headlight.

An increase in the number of moths observed daily, Monday through Friday, has been
rather Significant. It is not known whether this may be due to sugar accumulation
or possible "training" of the moths.

Numbers of Heliothis moths on sugar lines in the Jefferson Community, Desha County,
were compared with numbers taken in a standard blacklight trap in the same area

for 1964-65. See table on following page. Moths on sugar lines are expressed as
numbers per 1,000 row feet while actual numbers taken in the trap are listed. Data
Show that the light trap is rather inefficient in estimating field populations of
moths during June, July and part of August. During mid-to late August, relatively
more moths were taken in the light trap than were observed on sugar lines. This

is thought to be due to crops approaching maturity and becoming unattractive.

Sugar line data along with light trap data provide a clearer picture of the sea-
sonal occurrence of H. virescens moths.

During May 31 through July 2 from 3.3 to 24.3 percent Heliothis moths in the field
were H. virescens. In the light trap H. zea moths were low during this period but
no H. virescens were taken. After mid-August H. virescens were taken in the light
trap while none were observed on sugar lines. Sugar Line data show that peak moth
populations in the field occurred at approximately five-week intervals in 1965.

Many workers over a long period of time have reported a 30-day life cycle in lab-
oratory rearing at summer temperatures. The five-week peak has helped explain a
puzzling problem in that outbreaks of bollworm have occurred in soybeans in late
August approximately five weeks after July outbreaks in cotton.

Moth peaks did not show up in light traps as distinctly as they did on sugar lines
in 1965. Unpublished results of a previous study showed that peak moth numbers in
light traps may appear about one week later than peaks of eggs on cotton. This
would indicate that moths taken in light traps are older spent moths. It is known
that moths of all ages are observed on Sugar baits.

Factors other than populations have been studied in connection with this survey.
Although the full significance of shades of color of the bollworm moth is not
known, it has been determined that moths from pupae which were in diapause are
light in color. To further study the color factor, moths are classed as light or
dark and the data recorded seasonally and by host. Moths are collected and exam-
ined to determine the number of times females have mated. These data are recorded
seasonally and by host. A study is also being made of the possible differences
between hosts regarding the time of peak numbers and total numbers of moths during
the season.

This method of survey apparently could be used for other species of insects. Data
on other species were not collected; however, it was quite evident that moths of
cabbage looper (Trichoplusia ni), armyworm (Pseudaletia unipuncta) and green clo-
verworm (Plathypena Scabra) reSpond to the sugar Spray.

WEATHER OF THE WEEK ENDING OCTOBER 3

HIGHLIGHTS: For third consecutive week, widespread, substantial rain fell in the
previously-parched Middle Atlantic and Northeast States. It was also the fourth
week of cool temperatures for much of the eastern half of the Nation.

PRECIPITATION: A front that stretched from Colorado to North Carolina produced
rains from the central Rocky Mountains to Virginia on Monday, and then over most
of the Southeast as it moved to the Gulf of Mexico and the Atlantic Ocean. A new
storm developed west of Hudson Bay, moved southeastward, and brought substantial
rains to the northern Great Plains, the Great Lakes Region, and the Northeast at
midweek, and to most of the eastern half of the Country on Friday and Saturday.
Some light rains fell in the Far Northwest on Monday and in southern California
and southern Arizona on Thursday. Rain and snow fell in the northern Rockies,
portions of the northern Great Plains, and northern New England over the weekend.
Wide areas in the western half of the Nation received no rain or only light
sprinkles. Severe thunderstorms moved across northern Ohio Thursday. An associ-
ated tornado injured 22 persons in the suburbs southeast of Cleveland.

TEMPERATURE: At the beginning of the week, cool cloudy weather prevailed over the
northern two-thirds of the Nation and warm Sunny weather over the southern third.
Brisk northerly winds again brought unseasonably cold air into the northern Great
Plains at midweek, and afternoon temperatures remained in the 50's from eastern
Montana to northern New England through the end of the week. Temperatures dropped
to below freezing over portions of the northern Rockies, the northern Great Plains,
the Great Lakes Region, and the northern portions of the Appalachians and the
Northeast on one or two mornings. Mild temperatures continued over the Far South-
west. Readings were unusually high in the interior valleys of California; Red
Bluff registered 109° and Sacramento a record-breaking 103° on Thursday afternoon.
Strong southerly winds also brought warmer temperatures and clouds of dust to the
western Great Plains on Sunday. (Summary supplied by Environmental Data Service,
ESSA).

WEATHER OF THE WEEK ENDING OCTOBER 10

HIGHLIGHTS: High pressure produced typical Indian summer weather over most of the
Nation. Heavy thundershowers occurred over portions of Texas on TueSday, and in
Alabama and Georgia on Sunday. Hurricane Inez brought heavy rains to the Florida
Keys on Wednesday.

TEMPERATURE: The week began with a cold front extending from the Great Lakes to
Texas. After the front moved offshore over the Atlantic Ocean and Gulf of Mexico,
high pressure extending from the Pacific Ocean to the Atlantic brought Indian
summer weather, with blue skies, cool mornings, and warm afternoons. Temperatures
over the northern and central Great Plains climbed from the 20's and 30's on Wed-
nesday to the 80's by Thursday afternoon. Some Iowa stations recorded 23° on
Wednesday and Thursday mornings and 86° on Friday afternoon. A cold front pushed
into the Northwest Saturday, and by Sunday maximum temperatures from Washington
and Oregon to the Great Lakes were mostly in the 60's. Mild temperatures continued
in the central and southern Great Plains, with Fort Smith, Arkansas, registering
93° Sunday afternoon. The synoptic situation at the end of the week closely res-
embled that of the previous week. A cold front stretched from the Great Lakes to
Texas, while a massive High and extensive clear, cool weather covered the States
behind the front.

Weather continued on page 978.

PRECIPITATION: A cold front that stretched from the Great Lakes to Texas at the
beginning of the week produced scattered rain over most of the Eastern States on
Monday and Tuesday. Locally heavy thunderstorms brought up to 2.5 inches of rain
over Texas from the trans-Pecos eastward, with Houston reporting 2.78 inches on
Tuesday. Lighter thundershowers dotted the southwestern deserts Tuesday and Wed-
nesday. Hurricane Inez brought heavy showers to the Florida Keys on Wednesday
and light rain fell on the northern Pacific coast on Thursday. A fast-moving
cold front reached the Northwest Saturday afternoon; by Sunday, it stretched from
the Great Lakes to Texas (in almost the exact position of the front of a week
earlier) and was causing widespread showers and thunderstorms on the Mississippi
River to the Atlantic Ocean. A number of localities in Alabama and Georgia re-
ceived from 3 to more than 5 inches of rain late Sunday afternoon and evening.
Hail and high winds were associated with some of the thunderstorms; hail reached
golf-ball size and winds gusted to 63 m.p.h. near St. Louis, Missouri. Two large

WEATHER BUREAU'S 30-DAY OUTLOOK
MID-OCTOBER TO MID-NOVEMBER

Weather Bureau's 30-day outlook for mid-October to mid-November calls for temper-
atures to average above seasonal normals over most areas from the Rockies to the
Appalachians and also over the north Pacific coast. Below normal averages are
called for along the middle and north Atlantic coast as well as in California,
while near normal temperatures are indicated for unspecified areas. Precipitation
is expected to exceed normal over the west coast States and the western plateau.
Subnormal totals are called for east of the Continental Divide except for near nor-
mal in the northern Plains, the upper Mississippi Valley and the south Atlantic
coast and near to above normal in portions of the southern Plains. Elsewhere near
normal precipitation 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 $5.00 a year.

on one remaining puncture-vine plant at Sandy Beach, Oahu. Weevils purposely
introduced; complete kill expected within thirty days. (Haw. Ins. Rpt.).

A Change of Name for the Fuller Rose Beetle, Pantomorus godmani

(Crotch). (Coleoptera: Curculionidae).

In the Journal of the Entomological Society of Australia (N. S. W.), Vol. 2, 1956,
Chadwick published two papers. The first, pp. 10-20, "A Review of Fuller's Rose
Weevil (Pantomorus cervinus (Boheman)) (Col., Curculionidae)," is a review of
work done on the nomenclature, morphology, anatomy, and world and Australian dis-
tribution of this insect. He concludes that Pantomorus cervinus (Boheman) is the
correct scientific name and Fuller's rose weevil the correct common name of this
widely distributed insect pest. This weevil is listed as Pantomorus godmani
(Crotch), the Fuller rose beetle, in the latest "Common Names of Insects Approved
by the Entomological Society of America,'' December 1965. The second paper, pp.
21-34, "A Check List of the Brachyderinae (Col., Curculionidae) "Occurring in
Australia," lists all known references to that species.

COOPERATIVE ECONOMIC INSECT REPORT

ESTIMATED LOSSES AND PRODUCTION COSTS ATTRIBUTED TO
INSECTS AND RELATED ARTHROPODS - 1965

Introduction

Insect loss estimates have been published in the Cooperative Economic Insect
Report as individual presentations in past years. In an attempt to make the in-
formation more useful and more readily available, estimates from the various
States have been compiled in a single issue of the report.

The loss data in the following compilation were received from 16 States. The en-
tomologists preparing the estimates, together with the States from which they
report, are listed below.

Dale Fullerton Arizona
W. P. Boyer Arkansas
L. E. Jenkins Colorado
Paul P. Burbutis Delaware
Clarence E. White Illinois
Ray T. Everly Indiana
Wallace C. Harding, Jr. Maryland
Robert Flaskerd Minnesota
Ray Pratt Montana
Jon J. Rhine Nebraska
Gerald L. Nielsen New Mexico
Don C. Arnold Oklahoma
M. W. Meisch Texas

O. W. Isakson Virginia
Marlin S. Conrad Wisconsin
William D. Marks Wyoming

Copies of the compilation were sent to the various States involved for review
prior to release. Some suggestions for possible improvement in presentation were
made. These suggestions have been incorporated where possible.

Separates of this compilation are available from Survey and Detection Operations.

WEATHER OF THE WEEK ENDING OCTOBER 17

HIGHLIGHTS: A major cold air outbreak and a severe blizzard brought an end to
Indian Summer over much of the Nation and announced the approach of winter. A
tornado virtually destroyed a town in Iowa.

PRECIPITATION: A major storm developed over southeastern Montana late Tuesday and
by midnight Wednesday was centered over north central Nebraska. Heavy snow fell
in the Wyoming and Colorado Rockies, accumulating to 18 inches in some localities.
Ski resorts near Salt Lake City, Utah, welcomed 16 inches of snow but northerly
winds east of the Continental Divide drifted the snow badly, causing considerable
inconvenience and hardship. Seven persons lost their lives in the severe storm.
As the storm center moved eastward across Iowa, a cold front trailed southward to
Texas. The clash of polar air following the front with the tropical gulf air
ahead of it set off severe thunderstorms and tornadoes. Winds gusted to 80 m.p.h.
at Austin, Texas, to 70 m.p.h. at Winona, Minnesota, and from 50 to 60 m.p.h.

from South Dakota to the Texas Panhandle. Baseball-sized hail fell near Rochester,
Minnesota, and near Aldrich, Missouri. Smaller hail was reported at numerous
locations from Minnesota to Michigan and southward to Missouri and Illinois.
Vicious tornadoes occurred in Minnesota, Iowa, and Missouri. The worst of these
practically wiped out the town of Belmond, Iowa, on Friday afternoon. It killed

6 persons and injured 172, destroying 119 buildings and causing major damage to
160 and minor damage to 308. About 550 families suffered in some way from this
visit of the most destructive late-season tornado ever to occur in the State.
Significant rains fell along the northern Pacific coast, Texas upper coast, coast-
al Louisiana, the middle eastern coast of Florida, over a few spots in the North-
east, and in the lower Rio Grande Valley.

TEMPERATURE: During the first part of the week, southerly winds brought warm,
moist gulf air northward over the central Great Plains, with temperatures reaching
the 80's and 90's as far north as Nebraska and Iowa. A cold front extended south-
ward west of this stream of warm, moist air. Behind the front northerly winds
(gusting to 60 m.p.h. at Cheyenne, Wyoming) tumbled the temperatures 40° or more
in some areas. The coldest air mass of the season plunged southward, bringing
freezing temperatures to the higher portions of California, central Arizona,
central New Mexico, and the High Plains of Texas. Temperatures dropped to near
zero in the Wyoming and Colorado Rockies. Some of the coldest temperatures of

the week included 6° below zero at Farson, Wyoming, and 5° below zero at Fraser,
Colorado. Temperatures averaged below normal from the Pacific Ocean to Lake
Michigan in the north and to the Appalachians in the south. From Indiana eastward
to the Atlantic Ocean and east of the southern Appalachians, temperatures averaged
slightly above normal. In Ohio and vicinity, temperatures averaged above normal
for the first time in 6 weeks. (Summary supplied by Environmental Data Service,
ESSA).

WEATHER OF THE WEEK ENDING OCTOBER 24

HIGHLIGHTS: Heavy showers fell over the Appalachians and the Northeast, while a
storm in the Northwest brought rains to the coast and heavy snow to the Cascades.
In between, high pressure and clear cool weather predominated from the Great
Basin to the Appalachians.

TEMPERATURE: Temperatures averaged below normal over most of the Nation. Arkansas
and nearby portions of neighboring States were 9° or more colder than normal.

Only the California coast, the Florida Peninsula, and the Georgia and Carolina
coast averaged near or slightly above normal. San Antonio, Texas, set a new low
temperature record for so early in the Season when the temperature dropped to 34°.
Pueblo, Colorado, set a new record with an 18° reading.

PRECIPITATION: Early in the week, a low pressure system over the eastern United
States produced rain from the central Great Plains to the Atlantic Ocean. The
heaviest fell from the Appalachians to the middle Atlantic coast, with Tuesday's
and Wednesday's totals exceeding 3 inches from Atlanta, Georgia, to Philadelphia,
Pennsylvania. Up to 2 inches of snow fell in the mountains of West Virginia.
Rain continued to soak the northeastern States on Thursday. Also, on Thursday, a
new storm moved into the Pacific Northwest. It brought heavy rain to the coast,
almost 4 inches at Astoria, Oregon, and unusually heavy snow to the Cascades
(snow accumulated to 10 inches at the 3,000-foot level and to 30 inches at 5,500
feet). The snow continued in the Cascades on Friday while spreading to the high-
er elevations of the northern Rockies.

Aphis craccae Linnaeus, an Aphid Newly Discovered
in the United States (Homoptera: Aphididae)
Louise M. Russell 1/

Aphis craccae Linnaeus, a Palearctic species, was collected from wild vetch at
Augusta, Maine, July 7, 1966, by J. O. Pepper of the Pennsylvania State University,
and A. N. Tissot of the University of Florida. As far as known, this was the first
collection of this aphid in the United States. On August 21, 1966, I collected
eraccae from Vicia cracca at Crown Point, Essex County, New York, and L. L.
Pechuman of Cornell University took samples from Vicia sp. on Wellesley Island,
Jefferson County, New York, August 31 and September I, 1966. Although these are
the only known collections of craccae in the United States, it is possible that

the species is present in New Hampshire, Vermont, and other northern States.

A. craccae had been found previously in Canada. It was reported from Vicia cracca,
Quebec, by F. W. Quednau (Canad. Ent. 98(4): 426, 1966), and was observed in
Fredericton, New Brunswick, in early summer, 1966, by M. E. MacGillivray and Jean
Adams of the Canada Department of Agriculture. Both of these workers, who are
familiar with the aphids of the Fredericton area, stated that they had not observed
the species before this year. Examination of aphids from vetch in the collection
of the U. S. National Museum did not reveal examples of craccae taken before 1966.
Thus it is likely that the aphid is comparatively new in North America.

Samples collected July 7 in Maine and July 11 in New Brunswick consisted entirely
of viviparous forms. In the New York collections, taken in August and September,
however, the majority of Specimens were oviparous females, but a few males and
viviparous females were present. In all collections that I have examined, the
aphids were densely clustered on the terminal growth of the vetch (principally on
the stems but with a few on leaves and seed pods), nymphs were more numerous than
adults, the insects were not attended by ants, and there was no evidence of para-
sitism.

Distribution - United States: Maine, New York; Canada: New Brunswick, Quebec;
all Europe according to G. Remaudiere (Fauna terrestre et d'eau douce des Pyrénées
- Orientales, fasc. 2: 16, 1959); China and Japan according to C. C. Tao (Agr.
Res. (Taiwan) 8(1):5, 1958).

Hosts - Vicia cassubica, V. cracca, V. dumetorum, V. faba, V. hirsuta, V. lutea,
V. pSeudocraccae, V. Sativa, V. tenuifolia, V. villosa, Vicia Spp. Although Aphis
eraccae haS been reported from each of these species of Vicia it is recorded most
frequently from cracca, less frequently from sativa, and infrequently from the
other species. Frej Ossiannilsson (Lantbrukshogskolans Ann. 30: 463, 1964) listed
craccae only on V. cracca in Sweden, and several other European workers have re-
ported the aphid on this plant. Indeed, U. Falk (Wiss. Ztschr. der Univ. Rostock
7(4): 628, 1957/58) stated that in experiments in Germany, craccae left all species
of Vicia except cracca within a few days. Tao (op. cit.) reported craccae from
Vicia Sp. in China and Japan, and (Plant Protect. Bul. (Taiwan) 4(3): 106, 1962)
from Vicia faba. The last is the only report I have found of craccae on V. faba.
In America craccae is known from V. cracca and Vicia sp. It iS poSSible that the
unidentified Vicia also is cracca for this is a common species in New Brunswick,
Maine, and New York.

Economic importance - Aphis craccae is not reported to be seriously injurious even
though it lives on V. cracca and V. sativa, species that are sometimes grown as
agricultural crops in Europe, and on V. faba, the common broadbean. In new
Brunswick and New York, where the aphid occurred abundantly, there was little
apparent damage at the time I observed the infestations. In Crown Point, New York,

l/ Entomology Research Division, ARS, U. S. Department of Agriculture,
Washington, D. C.

- 1022 -

the vetch grew in a meadow that was predominantly alfalfa with a few red clover
plants and a little timothy grass. Though the vetch and other legumes were some-
times nearly contiguous, aphids were present only on the vetch. Aphis craccae has
been tested in the transmission of plant diseases. In experiments, it Success-
fully transmitted bean yellow mosaic and cucumber mosaic, but did not transmit
cabbage black ring spot, according to J. S. Kennedy, M. F. Day, and V. F. Eastop
(A Conspectus of Aphids as Vectors of Plant Viruses, p. 55, 1962).

Distinguishing characters - In North America Aphis craccae is most likely to be
confused with A. craccivora Koch and A. fabae Scopoli. All are "black aphids"

that live on vetch, but craccivora and fabae live on many other plants as well.
In this country living specimens of craccae can readily be distinguished from the
other two species by its dense covering of gray or whitish, coarse, pulverulent,
waxy secretion. Both craccivora and fabae lack such a secretion in the adult
stage. Also in America, cleared, slide mounted specimens of the three species may
be separated on the basis of morphological characters. The most conspicuous
differences are in the comparative length of the cornicles, and the number of
setae on the cauda, in winged and wingless specimens; in the sclerotization of
the abdomen in apterae; in the number of Secondary Ssensoria on antennal segment
III and their presence or abSence on IV in alatae. The key on the following

page will help to separate the three species.

WEATHER OF THE WEEK ENDING OCTOBER 31, 1966

HIGHLIGHTS: Most of the Nation enjoyed mild, sunny days and clear, cool nights
with practically no rain.

PRECIPITATION: Skies remained cloudless from Burbank to Boston and from Montana
to Mississippi. Only a few stations in that wide area reported any precipitation
whatsoever and these received only light sprinkles. Many States reported "no rain
at any station." The 1l-month drought in the Great Basin intensified. The Far
Northwest received light precipitation on Wednesday and Saturday. Rain fell at
the lower elevations and snow in the mountains. Light snow flurries fell in north-
ern Minnesota and Upper Michigan with sprinkles in northern Lower Michigan. The
lower Rio Grande Valley received light rains on Monday and light showers fell in
northern New England on Saturday. Heaviest rainfall occurred from the southern
Appalachians to the Atlantic Ocean. Some mountain areas received 1-2 inches with
more than 5 inches at Newnan, Georgia. The Piedmont received 0.5 to 1 inch while
less than 0.5 inch fell along the coast.

TEMPERATURE: Typical autumn weather with high pressure and clear, quiet condi-
tions prevailed coast to coast. Temperatures averaged unseasonably mild in the
West and cool in the East. Record-breaking warmth occurred over portions of the
western half. Temperatures climbed to the 70's along the Canadian border of
Montana and North Dakota and to the 80's as far north as South Dakota. The mercury
dropped 40° to 50° during the lengthening, calm, cloudless nights but climbed again
to near-record maximums the following afternoons. In contrast, cool weather con-
tinued over the East. Afternoons were mild but the mercury dropped sharply after
sundown. On Thursday morning, freezing temperatures occurred as far south as
northern Mississippi. North of the Ohio River, freezing temperatures have ended
the growing season for most crops. This was the tenth consecutive cold week in
northern Louisiana, Mississippi, and Tennessee. (Summary supplied by Environmental
Data Service, ESSA).

A Change of Name for the Fuller Rose Beetle, Pantomorus godmani

(Crotch). (Coleoptera: Curculionidae).

In the Journal of the Entomological Society of Australia (N. S. Woods VOLS 25 OSs,
Chadwick published two papers. The first, pp. 10-20, "A Review of Fuller's Rose
Weevil (Pantomorus cervinus (Boheman)) (Col., Curculionidae) ," is a review of work
done on the nomenclature, morphology, anatomy, and world and Australian distri-
bution of this insect. He concludes that Pantomorus cervinus (Boheman) is the
correct scientific name and Fuller's rose weevil the correct common name of this
widely distributed insect pest. This weevil is listed as Pantomorus godmani
(Crotch), the Fuller rose beetle, in the latest "Common Names of Insects Approved
by the Entomological Society of America,'' December 1965. The second paper, pp.
21-34, "A Check List of the Brachyderinae (Col., Curculionidae) Occurring in
Australia," lists all known references to that species.

WEATHER OF THE WEEK ENDING NOVEMBER 7, 1966

HIGHLIGHTS: Last week was warm in the Far West and cold in the Central and Kast.
Heavy Snow fell from Michigan to Tennessee; record cold reached the Gulf of Mexico.

PRECIPITATION: A major storm system brought record cold weather and record early
Snows to central areas of the Country. By Tuesday, several inches of Snow had
fallen in Michigan and flurries over the northern and central Great Plains with
rain from the snow area southward to the Gulf of Mexico. On Wednesday the storm
center intensified over the southern Appalachians and piled up to a foot of snow
in parts of Michigan, Indiana, Ohio, Kentucky and Tennessee. As the storm moved
northeastward, rainfall totals exceeded 5 inches in parts of New England. In the
storm's wake, rain persisted from Arkansas to New England while several inches of
snow fell near the Great Lakes on Saturday. At weekend, the first general storm
of the season brought moderate to heavy precipitation to the California area. Snow
fell above 2,500 feet in the north and above 5,000 feet in the south. Snow also
fell from the Cascades to the eastern slope of the northern Rocky Mountains. A
large dry area extended from Nevada and Utah to the lower Rio Grande Valley. Much
of the central and northern Great Plains received little or no precipitation.

CITRUS

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 cur-
rent U. S Weather Bureau's 30-day outlook will be normal. Therefore, the fore-
casts given below cannot be viewed with the same degree of confidence as those in
the "Citrus Insect and Disease Summary" usually released twice each month.

CITRUS RUST MITE (Phyllocoptruta oleivora) expected to increase through mid-Novem-
ber followed by gradual decrease. Population will be at high level until early
December with about 60 percent of groves having important infestations. CITRUS
RED MITE (Panonychus citri) expected to be moderately numerous through November
with scattered heavy infestations occurring until mid-December. TEXAS CITRUS MITE
(Eutetranychus banksi) will be less common than citrus red mite and often occur in
same grove. October and early November infestations will be fewer and lighter than
in recent years. Scattered heavy infestations expected mid-November through
December. GLOVER SCALE (Lepidosaphes gloverii) not expected to depart from current
moderate level. YELLOW SCALE (Aonidiella Citrina) will fluctuate near present mod-
erate to high range. CHAFF SCALE (Parlatoria pergandii) will remain low and below
average. WHITEFLIES expected to be near normal abundance and not of great im-
portance. (W. A. Simanton).

Citrus Insect Situation in Florida - End of October - CITRUS RUST MITE infested 67
percent of groves (norm 65 percent); 54 percent economic (norm 43 percent). Pop-
ulation above average and in high range and appears to have reached fall peak.
Gradual decrease expected after mid-November and will be more apparent on fruit
than on leaves. Highest districts west, south, and north. CITRUS RED MITE in
fested 35 percent of groves (norm 35 percent); 12 percent economic (norm 10 per-
cent). Population near average and in low range; further increase expected
through November. Highest districts north, central and west. TEXAS CITRUS MITE
infested 21 percent of groves (norm 32 percent); 5 percent economic (norm 11 per-
cent). Population still below normal and in low range despite recent upward trend.
Further increase will occur but heavy infestations not expected to be numerous.
Highest districts north and east. YELLOW SCALE infested 67 percent of groves; 18
percent economic. Populations at record high level for October. Further increase
expected. Highest districts east, central, west, north, south. GLOVER SCALE
infested 57 percent of groves; 11 percent economic. Population average for Oct-
ober and in low to moderate range. Increase expected. Highest districts central,
east and south. PURPLE SCALE (Lepidosaphes beckii) infested 60 percent of groves;
7 percent economic. Population Slightly below average; in low to moderate range
but infestations not expected to become much heavier than present. Highest dis=
tricts central, south and east. CHAFF SCALE infested 39 percent of groves; 6 per-
cent economic. Will continue below average abundance; although increase expected,
population will not exceed moderate level. Highest districts east, central, south.

TEMPERATURE: The early season snow and rain Storm brought record-breaking cold
from the central Great Plains to the Deep South. On Thursday morning, Topeka,
Kansas, registered 10°, a new early season record, and New Orleans, Louisiana,
with 28° set a new November record. Mild temperatures retruned to the central
Plains and South over the weekend with readings in the 70's over most of Kansas.
As week ended, however, a new cold wave pushed across the Canadian border, accom-
panied by near zero temperatures in Montana and the Dakotas. On Tuesday, a desert
wind pushed the mercury to record highs for so late in the season in the central
and south coastal sections of California. Los Angeles with 101° broke an 82-year
November record. San Diego broke a 95-year record with 97°. (Summary supplied

TECHNIQUES TO DETERMINE LOSSES

Selected References 1960-1966
Introduction
Part I

Interest in the need for scientific methods for determining losses caused by in-
sects continues to increase. It is believed that a survey of the literature in
this area will be helpful in establishing the present status of the work and pro-
vide an available reference source for further studies. The references below
cover the period 1960-66. Additional lists will be issued as they are prepared.
Separates of this list are available from Survey and Detection Operations.

WEATHER BUREAU'S 30-DAY OUTLOOK
MID-NOVEMBER TO MID-DECEMBER 1966

Weather Bureau's 30-day outlook for mid-November through mid-December calls for
temperatures to average above Seasonal normals from the central and southern
Plateau eastward through the central and southern Plains to the Appalachians. Be-
low normal temperatures should be confined to the Northeast and the Northwest while
near normal values are expected in unspecified areas. Precipitation is expected

to exceed normal over the western quarter of the Nation and in parts of the south-
ern Plains. Subnormal totals are indicated for most areas east of the Mississippi
as well as eastern portions of the northern and central Plains. In unspecified
areaS near normal precipitation 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 $5.00 a year.

SPRUCE BUDWORM SURVEY METHODS IN THE NORTHERN REGION
T. T. Terrell 1/

Detection Surveys - New outbreaks of spruce budworm, (Choristoneura fumiferana
(Clem.)) are frequently discovered during aerial detection surveys.

Foliar damage caused by spruce budworm is most evident in the Northern Region
during mid-August. Flights are made, however, from about August 1 through Sep-
tember 15. Before this period, light foliar damage has not turned red enough to
be readily seen; after mid-September, fall storms decrease the evidence of feeding.

Flights are made over the timber type from 8 a.m. to about 2 p.m. Shadows are too
long on northern and western slopes to permit earlier flights, and rough air ter-
minates the afternoon flights.

Early morning light is best, however, for detecting infestations because it shows
red better than noon-time light.

Flights are made at approximately 800 feet above the terrain. A contour pattern
is flown in most of the Northern Region because the terrain does not lend itself
to strip flights. We strive for practically 100-percent coverage of areas survey-
ed.

When evidence of spruce budworm damage is discovered, the outbreak areas are map-

ped on 4-inch to-the-mile maps.

Biological evaluation (Aerial) - Biological evaluations of spruce budworm include
an aerial survey of known infestations. These are made in much the Same manner as

detection surveys. The damage is classified as to degree of intensity; light,
moderate, or heavy. These classes cover fairly large areas of perhaps a small
drainage or some topographical unit and are described by appearance as follows:

Light - The damage ranges from barely visible to reddening of the upper
one-fourth of the tree crown. Damage is not necessarily continuous
throughout the stand. There may be a few heavier spots of damage.

Moderate - Damage is clearly visible. The upper one-third to one-half
of the crown is red. The damage is not necessarily continuous, and thére
may be some heavily damaged spots.

Heavy - Damage is visible on most trees to the bottom of the crown. The
damage is nearly continuous throughout the stand. There may be some top
killing.

Subsequent ground examinations usually show that aerial observation classes fall
into the following percentages of defoliation of current needle growth: Light
25 to 40, moderate 35 to 60, heavy 55 to 85.

Biological evaluation (Ground) - Samples of foliage are collected from the lower
midcrown of intermediate trees to determine the number of budworm egg masses.

Two samples each of sufficient quantity to cover a 4 by 4 foot canvas are col-
lected from opposite sides of one-tree plots located in various parts of the area
surveyed. They are taken in September or October after the eggs have hatched.
The foliage is placed in large plastic bags and brought into the laboratory and
stored in a cold room (about 38° F.). Twenty to 30 one-tree plots per area are
desirable.

= 1072 = Survey Methods

A crew of temporary employees is then hired to examine the foliage and remove all
needles that have foreign material attached. This crew is supervised by an en-
tomologist who measures the sample and estimates the percentage of current de-
foliation We have observed that women are more adept to this task because they
seem to have more patience in performing routine, monotonous jobs.

The foliage is measured by spreading it loosely on a canvas covered table marked
gridiron fashion from an end line to show the number of square inches of surface
up to 2,000. The foliage is discarded.

The percent defoliation of current growth is estimated by examining 50 new growth
shoots. Research note INT No. 86 on the following page will explain the procdure.

The complement of foliage remaining from previous years is also recorded because
it has a bearing on the trees' chance of survival when current defoliation is
severe.

The foliage is then passed to the examiners. The examiners remove and place all
the needles, with foreign material attached, into pill boxes. These needles are
then examined by the entomologist who removes the needles having budworm egg
masses. He then separates the current year's egg masses from those of previous
years. Old egg masses are discarded because they were found to be invalid as a
measure of egg populations for the previous year in the Northern Region. Current
egg masses are also examined to determine the percent parasitized by Trichogramma

sp.

The graph below is used to predict the defoliation for the next season. It shows
the correlation between egg masses and subsequent defoliation in the Northern
Region, and it is quite accurate in 3 out of 4 years.

This estimate and all information regarding the past history of the outbreak are
the bases of recommending for or against control projects.

ESTIMATING DEFOLIATION CAUSED BY SPRUCE BUDWORM FROM UNDAMAGED SHOOTS 1/

Tom T. Terell 2/

Spruce budworm (Choristoneura fumiferana (Clem.)) is a destructive pest in Douglas-
fir forests, particularly in Montana, where more than 4 million acres of forest
have been infested during the past decade. Surveys and control projects in in-
fested areas have required thousands of man-days during the period of the outbreak.
Much of this time is spent making operational surveys to delineate areas of in-
festation. Entomologists and foresters use various methods for measuring budworm
activity, but estimates of defoliation caused by budworm larvae feeding on new-
growth shoots is most commonly used. Damage to foliage is expressed in percent

of foliage destroyed. All of the several methods for estimating defoliation re-
quire considerable field training.

In 1959 and 1960, while measuring defoliation on new-growth Douglas-fir shoots in
Montana, an inverse relation was found between the percent of undamaged shoots and
the percent of defoliation. This relation offers a simple method of estimating
defoliation for survey personnel. Defoliation can be estimated by merely deter-
mining the percent of undamaged shoots which are easy to recognize and count.

The graph on the following page shows the relation between undamaged Shoots and
defoliation. The data are from 27 samples of foliage taken from permanent

sample plots in Montana. The data were taken incidentally to an appraisal of
defoliation and consist of notes taken by survey personnel. These notes clearly
showed that the numbers of shoots with no defoliation were related inversely to
the amount of defoliation for the sample. The degree of defoliation in the 27
samples ranged from light to very heavy and represented a good cross section of
defoliation in Douglas-fir in Montana.

The data were analyzed by a multiple curvilinear regression treatment when the
plotted data suggested a parabolic curve. T-tests of the coefficients show the
data to be highly significant at the 99-percent level. The regression in the
following figure was the basis for constructing the accompanying table, which
converts the percent of undamaged shoots into percent of defoliation.

In practice, 50 shoots examined at midcrown give a good sample, but 100 shoots
are better and give a count immediately convertible to percent.

WEATHER OF THE WEEK ENDING NOVEMBER 14, 1966

HIGHLIGHTS: The coldest weather of the season moved into the north central United
States while tropical air brought abundant precipitation to much of the East.

PRECIPITATION: The conflict between cold northerly winds and warm moist air from
the Gulf of Mexico caused moderate Showers, Sleet, and some freezing rain from
Arkansas to Michigan, while heavy thundershowers and a few tornadoes visited the
Deep South. Scattered localities from eastern Texas to Georgia received 4 to 5
inches or more. Most of the middle and lower Mississippi, the Ohio and the Ten-
nessee River Valleys received weekly totals exceeding 1 inch. Two-inch totals
occurred across northern Indiana and northern Ohio. Rains occurred daily in the
Pacific Northwest beginning Wednesday, and were still falling on Monday. Totals
exceeded 2 inches along the coast. Snow fell above 2,500 feet in Washington,
Oregon, and northern California, and above 5,000 feet in southern California,
Arizona, and New Mexico. Flagstaff, Arizona, received 6 inches of wet Snow on
Tuesday. Snow also occurred along the eastern slope of the northern and central
Rockies. Snow depths ranged up to 6 inches in western South Dakota and to 4
inches in western Nebraska.

TEMPERATURE: Last week's weather Showed a strongly contrasting temperature pat-—
tern, with temperatures over the northern Great Plains averaging 10° to 20° below
normal while temperatures over the Deep South were 8° to 12° above normal. The
cold daily became more and more intense until Tuesday, when some stations regis-—
tered minimums as much as 35° below the daily normals. Temperatures averaged near
normal from the Pacific Ocean to the Continental Divide. Unseasonably mild weather
prevailed over the Southeast and until Thursday in the Northeast, preceding a
cooler weekend. Early in the week, a cold front brought subfreezing temperatures
as far south as central Texas, the Boston Mountains in Arkansas, and the southern
Appalachians. Arctic air crossed into the northern Great Plains later in the week
with subzero temperatures over parts of 10 States. Some stations in North Dakota
remained below freezing for the entire week. Brisk southerly winds brought unusual
warmth to the eastern half of the Nation. In Kentucky, this warm week followed 9
consecutive cool weeks. The warm weather persisted throughout the week over the
Southeast, but temperatures in the Northeast returned to near normal over the
weekend. (Summary supplied by Environmental Data Service, ESSA).

WEATHER OF THE WEEK ENDING NOVEMBER 21, 1966

HIGHLIGHTS: Warm, dry weather prevailed over most of the Nation. Rain fell
daily along the central and northern Pacific coast. High pressure and warm air
persisted over the Rockies confining major storminess to the west coast.

PRECIPITATION: Most areas from the southwestern deserts to the middle and
Southern Atlantic coast and from the Dakotas to Mexico and the gulf received no
rain or only widely scattered, very light showers in the past week. Measurable
amounts fell at a number of stations from the Ozark Mountains in Missouri to
Louisiana and Mississippi. One area in Louisiana received more than 4 inches in
a locally heavy shower. A few heavy showers also fell in southeastern Florida.
Precipitation was frequent but light from the Great Lakes to New England. A
low-pressure area, stalled off the Washington coast since the previous week,
brought rains every day along the northern and central Pacific coast. Weekly
totals ranged from about 1 inch in the Puget Sound area to about 16.inches in
the Mendocino, California, vicinity, to less than 0.5 inch south of San Francisco.

SNOWFALL: Snow accumulated seasonally at higher elevations near the west coast
but was lighter in the Cascades and abSent from the Rockies. At midweek, light
Snows accumulating to as much as 2 to 4 inches in local areas fell in the upper
Great Lakes region, upper New York, and northern New England.

Formosan Subterranean Termite

Guidelines for Survey

Background

Formosan subterranean termite, Coptotermes formosanus, was first found in
continental United States July 1965 in a Shipyard warehouse at Houston, Texas.

An eradication treatment was applied against this infestation and it is believed
that the pest had been eliminated. New infestations were found, however, in May
and June 1966 in the port area of New Orleans and at Lake Charles, Louisiana. New
infestations were found, also, in the Houston shipyard and in a shipyard at Gal-

veston, Texas. Total sites known to be infested as of June 30 were as follows:
New Orleans 16, Lake Charles area 6, Houston 2, and Galveston 1. Damage has been
severe in many of the infested structures. The infestations in Lake Charles,

Louisiana, area were found principally in dead trees and stumps in a swampy wood-
land estimated to cover 3,000 acres. Since three shipyards have been found in-
fested and the focal point of the infestations in New Orleans centers on Camp
Leroy Johnson, a World War II Transportation Corps installation near Lake Pont-
chartrain, it appears that the pest may have been introduced through marine equip-
ment or cargo which had been infested and returned from overseas. Many of the
buildings on this site have been dismantled and removed from the property.

Formosan subterranean termite has been known in China, Guam, Hawaii, Japan,
Philippines, South Africa, and Taiwan for many years where its damage to various
structures has been a Serious problem. Introduced into Hawaii around 1900, it is
one of the Islands' most Serious pests, causing 2 to 3 million dollars damage
annually in Honolulu alone.

Geographical extent of survey

The gulf coast, the west coast, the Atlantic coast to Philadelphia and the Missi-
ssippi River to Memphis. All other inland waterways receiving material or equip-
ment from Asia or the known infested areas of Louisiana and Texas should receive
attention; also, any site in the United States where material suspected to be
harboring the termite has been received.

Survey through cooperator assistance

1. Contact commercial pest control operators, military pest control officers,
county agents, and others involved with pest control. Examine any termite
specimens on hand. Encourage them to submit specimens and to cooperate in
the program.

2. Work closely with plant quarantine inspectors at ports and follow up leads
supplied by them.

3. Contact power and telephone companies to determine if termite damage has
been seen on poles. Severe damage to treated poles has been found in
Louisiana.

Principal locations to be surveyed

1. Air and water ports, especially those serving countries or States infested
with the termite. In or near loading areas, inspect piers, structures,
pilings, logs, utility poles, and other timber in contact with the soil.

2. Military bases and business establishments receiving material from infested
areas. Give attention to warehouses, storage areas, and dumps containing
wooden debris.

- 1088 -

3. Old military camps.
4. Wrecking company storage areas and lumber companies.

5. Any other location including private homes suspected of having a termite
infestation.

Structures and materials to be inspected

Check all types of structures, piers, pilings, old boats and barges, posts, logs,
utility poles and other timber in contact with soil. Give special attention to
warehouses, Storage areas, buildings under repair and dumps containing wooden
debris.

What to look for

1. Watch for flights of the reproductives in the spring. There may be fall
Swarms in the warmer and more humid areas. Special attention Should be
given to picture windows in homes, service stations, street lights, and
other well-lighted areas. Light traps may be useful for detection of the
winged forms. Surveillance for winged forms is the most practical and
economical method of survey for this pest.

2. Cobwebs, window sills and any other areas around lights that may collect
debris should be closely examined for presence of winged forms or shed
wings of termites. This is perhaps the best method to determine rapidly
if there is a Formosan termite infestation in the area. Wings may not be
evident several months after the flight Season, however.

3. In structures check inside and out for tunneling that breaks through the
wall surface. Also watch for clusters of tunnels on the walls, in and
around door and window frames, and along adjoining areas of asbestos
Siding. Tap the walls, baseboards, floors, etc. A hollow sound or soft

surface suggests an infestation. Check for tunnels ‘and other evidence
of infestation underneath structures.

4. On wood products or debris, tunnels or damage may or may not be evident;
therefore it would be well to probe or to cut into interior of selected
samples for evidence of infestation.

Instructions for inspection of special structures

1. Concrete slab construction

a. Check for evidence of attack at or near any plumbing through the
slab. Entry around bathtub plumbing is common.

b. Look for earthen shelter tubes around baseboards.
c. Tap baseboards and around walls.
d. Check on side of foundation for earthen shelter tubes.

e. Check for wood that extends into or through the slab,
such as door frames.

2. Structures on piers or other types of raised foundations

a. Check for earthen shelter tubes on the foundation and on
ceilings and joists. Pay particular attention to areas
where the soil is moist, in corners, and areas poorly
ventilated. Hidden entrances through the bases of chimneys
and through hollow brick foundations are common.

Submission of specimens

Examine all termite Specimens collected. Sort out those suspected to be Coptoter-
mes formosanus and send them in for determination. The key on pages 1091-1098.
will aid in Screening specimens. Winged forms or soldiers are needed for positive
identification. Plant Pest Control Division employees Should follow instructions
in the Survey manual for preparation and submission of specimens. If cooperators
have a Standard identification form available, this may be used to submit speci-
mens. When forms are not available, send the following information with the
specimens: State, county, city, name and address of property, type of property,
degree of infestation, name and address of collector, date of collection. All
Specimens Should be preserved in alcohol. Although 70 percent alcohol is pre-
ferred, common rubbing alcohol will suffice. Submit at least 10 specimens if
available. Send suspect specimens to:

The following keys have been prepared as aids for recognition of Coptotermes for-
mosanus Shiraki. This species will key out to Coptotermes while all other indig-
enous or already established species known to occur in the United States will key
out to one or another of the Seven remaining genera. Separate illustrated keys
are provided for the imago and soldier castes. No key is provided for workers,
as members of this caste are difficult to identify generically; however, as the
mandible dentition of workers is almost the same as that of the imagoes, this
character can, in some cases, be used to identify subfamilies and genera. The
dentition characters noted in the Key Based on the Imago Caste (See Figs. 3A-H)

may, therefore, be helpful but must be used with caution as dentition in the imago

castes of Several genera is nearly identical.

WEATHER OF THE WEEK ENDING NOVEMBER 28, 1966

HIGHLIGHTS: Heavy snow fell in the Great Lakes area while dry weather continued
over most of the West. The week was unusually warm in the Central States.

PRECIPITATION: Moderate rains fell west of the Cascades in Washington, along the
Oregon coast, and in northern California. A storm developed in the central Great
Plains at midweek and in the next Several days produced precipitation over the
eastern half of the United States. Amounts were fairly generous from Arkansas to
the Great Lakes, but light along the gulf and Atlantic coasts. Snow fell above
3,000 feet in northern California and above 5,000 feet in the central Sierras.
The heaviest snow - up to 15 inches locally in Michigan - fell in the Great Lakes
area. Parts of Pennsylvania and New York received 5-6 inches. Lighter amounts
were general in parts of West Virginia and Virginia, with flurries in eastern
Tennessee and western North Carolina. Dry weather continued from Nevada and
southern California to the western Great Plains. An exception was Reno, Nevada,
where about 0.3 inch of rain fell during the week - the heaviest rain in the area
in almost a year. Wichita, Kansas, meanwhile, received only a light sprinkle.
Wichita has had less than 12 inches of rain Since January 1, 1966 - far less than
in any previous year of record and less than 40 percent of normal.

Weather continued on page 1107.

WEATHER OF THE WEEK ENDING DECEMBER 5, 1966

HIGHLIGHTS: Following several weeks of mild weather, successive blasts of Arctic
air brought the coldest weather since February to portions of the East. In the
West, warm weather continued.

PRECIPITATION: A deep storm in the Northeast moved out of the Country on Tuesday,
leaving an inch or more of precipitation in Pennsylvania and lesser amounts in
nearby States. Rain fell along the Washington, Oregon, and northern California
coasts every day of the week with Snow in the Cascades, northern Sierras, and
eastward to the Rockies. On Saturday, precipitation fell from the Pacific coast
to the eastern slopes of the Rocky Mountains. Weekly totals exceeded 6 inches
along portions of the Washington and Oregon coasts with about 2.5 inches reported
at Mount Wilson and nearby Los Angeles, California. Freezing rain, sleet, and
fog made driving hazardous in parts of Nebraska and Kansas and eastward to Michi-
gan and Ohio. The precipitation changed quickly to Snow in the northern portions
of Minnesota, Wisconsin, and Michigan.

SNOW: Moist air blowing across the Great Lakes released heavy Snow on the eastern
Shores. Snow accumulated to nearly 5 feet at Adams, New York. Elsewhere in
western New York, measurements ranged 12-45 inches. Some typical snowfall amounts
in other parts of the country included: Southern Appalachians, 1-4 inches; moun-
tains in West Virginia, 6 inches; western Pennsylvania, 6-12 inches; northwestern
Iowa, up to 4 inches; Black Hills of South Dakota, 4 inches. In the central and
southern Rockies snow accumulations were mostly limited to higher elevations in
Colorado.

TEMPERATURE: Bitter cold plunged far southward bringing freezing temperatures to
the gulf coast and to northern Florida. Stations in Georgia registered subfreez-
ing temperatures on 3-5 days. Temperatures dropped to zero or lower in the north-
ern States from the Rocky Mountains to New England; below-zero readings continued
in northern Minnesota all day on Thursday when the high at International Falls
was -6°. With high pressure centered over the East over the weekend, warmer air
flowed northward across the central Great Plains. Some stations in Wyoming and
South Dakota registered maximums in the 40's and 50's on Sunday afternoon. In
spite of some weekend warming, however, Missouri averaged 25° to 30° colder than
the previous week and about 8° below normal. Temperatures west of the Rockies
were generally warmer than normal during most of the week but cooled somewhat
over the weekend. It was the third warm week in the Rocky Mountains. (Summary
supplied by Environmental Data Service, ESSA).

WEATHER OF THE WEEK ENDING DECEMBER 12, 1966

HIGHLIGHTS: Rain continued along the Pacific coast, and heavy snow fell in the
Rockies. The coldest weather of the seaSon spread over the middle States, while
the warmest December weather of the century occurred in the Northeast.

PRECIPITATION: The still stationary storm off the Washington coast continuer to
dump daily precipitation from Washington, Oregon, and portions of California east—
ward to the Rocky Mountains. Utah and Nevada received the heaviest rains of the
year, while heavy snow fell in the Cascades, Sierras, and parts of the northern
and central Rockies. Snow amounts ranged generally from 6 inches to a foot or
more in parts of Nevada, Utah, Wyoming, Colorado, and New Mexico but reached 4
feet at Wolf Creek Pass, Colorado. A storm centered over the North Central States
brought a variety of weather from the Dakotas to Texas, eastward to the Appala-
chians and northeastward to New England. On Wednesday, thunderstorms dumped 3-4
inches of rain in parts of Illinois and 2 inches in Indiana. Freezing rain

glazed the highways from Kansas and Nebraska northeastward to Upper Michigan and
eastward to New England. Tornadoes damaged property in Missouri, Illinois, and
Indiana - where 1 person was injured. Over the weekend, heavy snow fell over
parts of Lower Michigan, northern Indiana, and northern Ohio, with lighter falls
northeastward to New England, while 2-3 inches of rain fell over the lower Ohio
River Valley. Kentucky reported the heaviest rains in 7 months and a few local

Nation. Syracuse, New York, registered 69° on Thursday and 70° on Saturday, the
highest temperatures on record for any December at that station. Trenton, New
Jersey, set a new high-temperature record on Saturday with a 72° reading. The
previous high reading for December (in 101 years) was 70°. Similar new records
were set in about 11 States. Frigid Arctic air spilled southward over the Central
States early Friday morning, with temperatures ranging from the 60's from Missis-—
Ssippi to Ohio in advance of the cold air, to the 30's from Oklahoma to Michigan
behind the leading edge of the cold air, and below zero in northern Montana and
North Dakota. The freezing line had plunged southward to the western portion of
the gulf coast by Sunday bringing a 27° temperature to Houston, Texas. Farther
north, the zero line enclosed western Kansas, much of the Colorado Rockies, and
probably extreme north-central New Mexico. Sub-zero temperatures occurred in at
least 11 States. For the week, temperatures averaged below normal over the
northern Great Plains, from Montana to Minnesota and southward to Nebraska and
Kansas, and above normal over the rest of the Nation. (Summary supplied by

WEATHER BUREAU'S 30-DAY OUTLOOK
MID-DECEMBER TO MID-JANUARY 1967

The Weather Bureau's 30-day outlook for mid-December to mid-January calls for
temperatures to average below Seasonal normals over the eastern half of the Nation.
Above normal temperatures are indicated for most of the northern and central
Plains, the southern Plateau, and the Pacific Northwest while near normal averages
are called for in unspecified areas. Precipitation is expected to exceed normal
over the gulf and south Atlantic coastal regions. Subnormal totals are called

for over the northern and central Plateau in the West, the northern and central
Plains, and the upper and middle Mississippi Valley. Elsewhere near normal pre-
cipitation 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 $5.00 a year.

HIGHLIGHTS OF THE OCCURRENCE OF INSECTS AND OTHER ARTHROPODS
IN CANADA, 1966

I. S. Creelman

Generally good growing conditions in most of the country resulted in excellent
crops and not too much infestation or damage due to insects occurred.

GRASSHOPPERS were very scarce in western Canada. Little damage occurred in
Alberta because of their late hatch, except to fall-seeded crops. A few areas in
southern Alberta had large numbers of grasshoppers. Grasshoppers were present
throughout Saskatchewan, but were the lowest since 1957. No significant damage
occurred in Manitoba, due to late hatching plus excellent growing conditions.

In the interior of British Columbia, CUTWORMS were less destructive than usual.
PALE WESTERN CUTWORM (Agrotis orthogonia) was widespread in Alberta, but for the
first time in ten yearS no damage was reported, partly due to cool, wet weather
last fall and this spring. Only light infestations are expected in east central
and southeastern Alberta in 1967 if the early season is warm and dry. Cutworm
activity was reported in Saskatchewan.due to a cool, wet spring. Scattered
damage to sugarbeets by RED-BACKED CUTWORM (Euxoa ochrogaster) was reported from
Manitoba. ARMYWORM (Pseudaletia unipuncta) waS not reported in Ontario. On the
whole, cutworms were Scarce in Ontario, but caused severe losses to field crops
and vegetables in the Quebec City district. BRONZED CUTWORM (Nephelodes emmed-
onius) was notably scarce in the Dartmouth area of Nova Scotia. VARIEGATED
CUTWORM (Peridroma Ssaucia) was troublesome in Newfoundland during August and
September on vegetables and ornamentals. WIREWORMS were reported widespread in
Alberta but caused little damage. WHITE GRUBS (Phyllophaga spp.) were commonly
present in Ontario but caused occasional damage only in scattered locations.

WHEAT STEM SAWFLY (Cephus cinctus) increased slightly from last year, but gener-
ally remained low to moderate and little damage was caused in Alberta. In
Saskatchewan some infestation was reported especially in the west central part
of the agricultural area, but again little damage occurred.

In Alberta GRAIN APHIDS occurred in high numbers during August and September
damaging late barley and cover crops and transmitting some barley yellow dwarf
virus. In the central and southern regions they damaged flax slowing the
ripening of that crop. ENGLISH GRAIN APHID (Macrosiphum avenae) was abundant on
wheat in Saskatchewan shortly before harvest and on fall rye, but caused little
damage. In Manitoba, aphids were reported on barley at Arborg.

In southern Alberta, ALFALFA WEEVIL (Hypera postica) extended its area of economic
damage around Lethbridge. A survey of the Niagara Peninsula and area from Lake
Ontario east to the Maine border failed to turn up any sign of this weevil,
although it is present in New York and Vermont close to the International Border.
Some SWEETCLOVER WEEVIL (Sitona cylindricollis) damage was reported early in the
season at Calgary and Berwyn in Alberta; Some heavy infestations occurred in east
central Saskatchewan, but no damage was reported.

Rape and mustard were damaged during the spring by a FLEA BEETLE (Phyllotreta
cruciferae) and in late Summer by DIAMONDBACK MOTH (Plutella maculipennis arvae
in the Prairie Provinces. Rape was damaged by RED TURNIP BEETLE (Entomoscelis
americana) in Saskatchewan, by CLOVER MITE (Bryobia praetiosa) in the Neepawa
region of Manitoba and by BERTHA ARMYWORM (MameStra configurata) near Brooks,
Alberta. A survey of southwestern Ontario, the region closest to the infestation
in Michigan, Indiana, Ohio and Illinois, United States, failed to locate a single
Specimen of CEREAL LEAF BEETLE (Oulema melanopus).

NORTHERN CORN ROOTWORM (Diabrotica longicornis) adults were plentiful and damage
by the insect is spreading north and east throughout the corn belt of southern
Ontario. Damage by second-generation EUROPEAN CORN BORER (Ostrinia nubilalis)

- 1151 -

was severe in some fields of late corn and on late-planted sweet peppers in
southwestern Ontario. For the first time in six years, damage by EUROPEAN CORN
BORER to sweet corn was of economic importance in southwestern Quebec. CORN
EARWORM (Heliothis zea) was conspicuously absent in Nova Scotia this year. CORN
LEAF APHID (RhopaloSiphum maidis) was scarce in southern Ontario. A SAP BEETLE
(Glischrochilus quadrisignatus) was unusually abundant throughout southwestern
Ontario on raspberries, Sweet corn and tomatoes and on sweet corn in some
districts of southwestern Quebec. BUMBLE FLOWER BEETLE (Euphoria inda) damaged
corn at Lethbridge, Alberta.

CABBAGE APHID (Brevicoryne brassicae) was more abundant than for several years in
the Victoria area, and heavy flightS of GREEN PEACH APHID (Myzus persicae) occurred
in the potato-growing areas of the Lower Fraser Valley of BritiSh Columbia.

Damage by ROOT MAGGOTS (Hylemya spp.) was light except to field beans in south-
western Ontario. They were preSent in normal numbers in Southwestern Quebec, but
caused severe losses in the Quebec City area, and caused Some concern on root
crops in Prince Edward Island. CABBAGE MAGGOT (H. brassicae), resistant to
Specific insecticides, appeared at Woodbridge, Ontario, and strains resistant to
ecyclodiene insecticides now have spread throughout the Province of Newfoundland.
Some difficulty also developed with control by organophosphates. BEET LEAF MINER
(Pegomya betae) waS more noticeable than usual in home gardens in interior

British Columbia, and SPINACH LEAF MINER (P. hyoscyami) was quite abundant in
some areas of southern Quebec. COLORADO POTATO BEETLE (Leptinotarsa decemlineata)
was very abundant in Essex County, Ontario, and more numerous than for 20 years

in Prince Edward Island. POTATO FLEA BEETLE (Epitrix cucumeris) was also numerous
in Prince Edward Island. Population of CARROT RUST FLY (PSila rosae) has been
increasing for three years in the muck-soil area of southwestern Quebec, but is
not yet considered an important pest there. EUROPEAN FRUIT LECANIUM (Lecanium
corni) was found on carrots in a field near infested elm trees in Nova Scotia.
IMPORTED CABBAGEWORM (Pieris rapae) waS more numerous than usual in Southwestern
Quebec, and a FLEA BEETLE (SyStena frontalis) was numerous again in the region

on a wide range of cultivated and wild plants. Injury to strawberry foliage by
the latter pest was reported in Some regions. No infestations of PEPPER MAGGOT
(Zonosemata electa) on peppers were reported by growers in Essex County,

Ontario, but large numbers were found on horsenettle. Populations of GREENHOUSE
WHITEFLY (Trialeurodes vaporariorum) were very high on greenhouse cucumbers

during May in Essex County.

EUROPEAN RED MITE (Panonychus ulmi) was favored by a hot, dry season in southern
Ontario and was vey prevalent in apple, pear, plum, sour cherry and peach. It
was, aS usual, a major pest in Quebec apple orchards, but in Nova Scotia PHYTO-
PHAGOUS MITES were not a Serious problem. ORIENTAL FRUIT MOTH (Grapholitha
molesta) remained at a low level and was well controlled in southern Ontario.
PEAR PSYLLA (Psylla pyricola) in the Niagara Peninsula was reduced to a low level
by the August drought. An outbreak of TENT CATERPILLARS (Malacosoma spp.)
occurred in eastern Ontario and in southern Quebec on apples with even more
defoliation expected next year. They also were pests in Nova Scotia orchards.

A second generation of CODLING MOTH (Carpocapsa pomonella) appeared on apples

in the Georgian Bay Region of Ontario where more than one generation is seldom
produced, and a partial third generation of RED-BANDED LEAF ROLLER (Argyrotaenia
velutinana) appeared in Norfolk County where two generations are normal.

Activity by APPLE APHID (Aphis pomi) was not prolonged. CODLING MOTH was trouble-
some in poorly sprayed apple and pear orchards in the Niagara Peninsula. In
Quebec, it is increaSing and in Nova Scotia it showed marked increase to about
three times its level of the past three years. APPLE MAGGOT (Rhagoletis
pomonella) remained a major pest in Quebec apple orchards, cauSing damage even

in commercial orchards and severe damage to small garden fruit trees. APPLE
SEED CHALCID (Torymus varians) was found in some orchards in southwestern Quebec.
PLUM CURCULIO (Conotrachelus nenuphar), which has not been a commercial problem
since 1959, was preSent in all apple-growing areas of Quebec and caused serious

= 1152 -

damage in some. PLUM CURCULIO and PLANT BUGS attacked peaches late in season in
Essex County. APPLE MEALYBUG (Phenacoceus aceris) continued to be present in
orchards in the Annapolis Valley of Nova Scotia, but did not cause as much damage
as last year.

POPLAR-AND-WILLOW BORER (Sternochetus lapathi) was more prevalent than in past
few years in the interior of British Columbia damaging poplar and willow. It
also was reported damaging small willows in southwestern Essex County, Ontario.
BRONZE BIRCH BORER (Agrilus anxius) Severely infested ornamental birches in the
Windsor, Ontario, area. LILAC LEAF MINER (Gracillaria syringella) continued very
abundant at Kamloops, British Columbia, and PEPPER-AND-SALT MOTH (Biston cogna-
taria) defoliated caragana at Lethbridge, Alberta. SPRING CANKERWORM (Paleacrita
vernata) was prevalent on trees in Saskatchewan and Manitoba, as were TENT
CATERPILLARS in Eastern Canada. EUROPEAN CRANE FLY (Tipula paludosa) is now
found from the seacoast to the east boundary of the municipality of North Surrey,
British Columbia. This area includes built-up areas of Vancouver, Burnaby, New
Westminister and South to the International Boundary. Most damage so far is to
lawns.

ROCKY MOUNTAIN WOOD TICK (Dermacentor andersoni) appears to be as abundant as
usual. The tick problem is acute in the Dog Creek area. Wild foxes were
paralyzed, as well as animals normally affected. Five young children were
reported paralyzed in Alberta and British Columbia; all recovered upon removal
of the ticks. CATTLE WARBLE infestations continued to be low compared with
those of the 1950's. The current low infestation began in 1959 and has remained
consistently low since 1962. CATTLE LICE were quite prevalent in the Peace
River District. MOSQUITO populations were generally light in British Columbia,
although unusually late reports of floodwater species in Kamloops suburbs were
received in September.

Several household and stored product pests of note were: CLOVER MITE (Bryobia
praetiosa) in Ontario, British Columbia and the Quebec City area; FLEAS on pets
in Ontario and Quebec; and STRAWBERRY ROOT WEEVIL (Brachyrhinus ovatus) in the
Ottawa area and in Prince Edward Island. LARDER BEETLE (Dermestes lardarius)
was numerous in Prince Edward Island, but scarce in Ontario. LESSER MEALWORM
(Alphitobius diaperinus) was collected from chicken litter at Coaldale, Alberta.
A BRUCHID (Bruchidius unicolor) heavily infested seed of sainfoin brought into
Alberta from British Columbia.

WEATHER OF THE WEEK ENDING DECEMBER 26, 1966

HIGHLIGHTS: This was the coldest week of the Season in most areas. Parts of the
East received the heaviest pre-Christmas snowfall on record.

PRECIPITATION: Several snowstorms occurred. One fast-moving storm left 4 inches
of Snow in Muskegon, Michigan, and then moved eastward across northern Ohio, New
York, Pennsylvania, Maryland, and Delaware. Up to 9 inches of snow fell in the
higher elevations of Maryland. A midweek storm spread snow from Montana eastward
across the adjacent Great Plains. The major storm of the week developed over the
southern Great Plains shortly after midweek. After dumping 18 inches to 2 feet of
Snow in the Ozark region, the storm moved eastward to Virginia and North Carolina
and then northeastward to New England. Some typical snowfall amounts include:
15-18 inches at Mountain Home and Table Rock Dam, Arkansas; 10 inches at Roanoke,
Virginia; 16 inches at Philadelphia, Pennsylvania; 12 inches at Wilmington, Dela-
ware; 9 inches at Baltimore, Maryland, and Washington, D. C.; 19 inches at Albany,
New York; 13 inches at Syracuse; and a foot or more in upper New England. On
Christmas Day, snow covered most of the northern half of the Nation. In the East
the snow cover extended as far south as North Carolina with accumulations of 5

inches in the mountains, and about 1 inch in the northern Piedmont. As the
"Christmas" storm moved out of the country, on the 26th a new Snowstorm developed
in northeastern Arizona. It dumped heavy snow over the southern and central Rocky

Mountains and eastward to the Missouri River and was continuing into the new week.

TEMPERATURE: The coldest weather of the season came to most of the United States.
Temperatures dropped moderately west of the Rocky Mountains and Sharply on the
eastern Slope and across the Great Plains to the Gulf of Mexico. Temperatures in
the 50's and 60's were common from South Dakota to Kansas on Tuesday, but Thursday
brought sub-zero readings to this area. The severe temperature drop came at mid-
week over the Central and Northeast and to Florida at the weekend. Temperatures
over the northeast quarter of the Nation remained below freezing throughout the
week. South Dakota, Nebraska, and portions of nearby States averaged 10°-20°
colder than the previous week. Some parts of the Colorado Rockies registered 10°-
30° below zero on 1 or 2 days. (Summary supplied by Environmental Data Service,
ESSA).

Volume 16 Index

1966

INTRODUCTION

The 1966 index is a consolidated index, with common and scientific names appearing in
alphabetical order. Page numbers appear only under the scientific names, except for
general common names such as aphids, bees, leafhoppers, mites, etc.

The explanations that follow will aid in the use of the 1966 index.

1. Page numbers underlined represent references to "Summary of Insect Conditions in
the United States - 1965."

2. For convenience of use, all references concerning light trap collections for a
particular species are listed at the end of pagination for that species under this
heading.

3. 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, except
for those insects or groups of insects where scientific names were not reported.
In such instances, page references will be found under common names.

4, A combination of both common and scientific names of an insect or pest may not
appear on the page referred, but one or the other will be present.
