WEATHER OF THE WEEK ENDING JULY 1

HIGHLIGHTS: Temperatures ranged widely but averaged below normal over most of
the Nation. Many areas east of the Continental Divide received generous rains.

PRECIPITATION: Tropical storm Candy moved northward across eastern Texas early
in the week. The winds decreased so it was no longer a "'tropical storm" but it
remained an immense rainstorm system as it crossed Arkansas into Missouri, turned
northeastward, and continued to Lower Michigan. Numerous stations in Texas
received from 5 to 10 inches of rain. Large areas received 3 to 5-inch totals.
The torrential rains caused flooding in many local areas. Numerous tornadoes
occurred in connection with the storm. One of these destroyed the Morning Star
School in the Hot Springs, Arkansas, vicinity besides causing other damage.

Other tornadoes occurred from Colorado and Kansas to Iowa and Missouri but,
fortunately, most of them hit open country with little or no damage. As the rains
drenched the eastern half of the United States, sunny skies prevailed over the
western half until late in week when light drizzle began to dampen Washington
coast. The weekend brought light snow in the higher Rockies, light rains to the
northern Great Plains, and light to locally heavy showers in Missouri, Illinois,
and the east coast of Florida.

TEMPERATURE: Hot weather prevailed over the West early in the week. Many desert
Tocations registered maximums exceeding 100° on several days and afternoon readings
of 90° or higher were common on Tuesday and Wednesday over most of the area west
of the Continental Divide except near the Pacific coast, Temperatures | over the
West dropped sharply after Wednesday. Medford, Oregon, registered 102° on
Wednesday but no higher than 75° on Friday. The temperature at Ely, Nevada,
plunged from 90° on Friday afternoon to 23° by Sunday morning. Hot humid weather
prevailed over the East early in the week with maximums in the 90's as far north
as southern Pennsylvania and early morning temperatures in the 70's as far

north as Ohio. The warm humid weather persisted from the Gulf of Mexico to the
Ohio River until Tuesday when cooler air began to move into the Great Plains, the
Great Lakes region, and New England, By Wednesday morning, the temperatures over
the northern Great Plains had tumbled to the 40's. On Thursday afternoon, temper-
atures from the Great Lakes to the Ohio River were mostly in the 60's but the
Great Plains warmed to the 90's. Many stations from western and central Kansas
southwestward to the Rio Grande registered 100° to 108° on Friday afternoon. By
Sunday afternoon, the East was becoming uncomfortably hot and humid. New York
City and Philadelphia registered 94° and Washington 96° on Sunday afternoon,

EUROPEAN CORN BORER (Ostrinia nubilalis) - NEW HAMPSHIRE - First hatch June 19

at Hollis, Hillsborough County. (Sutherland). NEW YORK - Fall emergence in
cages nearly ended by June 20; trap catches above normal. Hatching evident in
whorls on 10+ percent of plants. Mostly second instars with one third instar
June 19. Egg masses in Livingston County; no hatch as of June 21. (N.Y. Wkly.
Rpt.). MARYLAND - Field corn infestations ranged 0-85 percent in central section

trap at Centreville, Queen Annes County. (U. Md., Ent. Dept.). Whorl infestations
ranged 10-50 percent on advanced plants. (Md. Ins. Notes). VIRGINIA - Damage to
potatoes heavier than expected considering low overwintering numbers in fall 1967
on Eastern Shore. Most borers pupating. Few newly emerged females collected
night of June 23; adult emergence expected soon. Peak moth flights for second
and third broods should occur around July 5 and August 15, respectively, at
Painter. Seasonal variation may cause much divergence. Generally, peak moth
emergence will occur within 10 days of above dates. Emergence will be "staggered"
again in 1968; weekly treatments will be necessary on peppers, peas, and other
susceptible crops. (Hofmaster). TENNESSEE - Infested 45-50 percent of 2 south-
central area fields; some damage in garden corn. (Quillin, Beeler). ALABAMA -
Older larvae heavy and pupation very heavy in early corn, especially sweet corn,

cent of early tasseling sweet corn in southern districts. Corn less than 24
inches (whorl height) tall. Most fields escaped first-generation damage. Larval
mortality 80-100 percent in damaged fields. Larval infestations ranged 4-80
(average 32) percent on 30 to 60-inch field corn; larval mortality 30-90

(average 60) percent. Second and third instars dominant throughout southern
districts. (Huber).

MICHIGAN - First-brood flights declined to few occasional specimens in southern
areas. Main flight further northward began in Montcalm County June 18, two weeks
later than in Lenawee County. (Newman). ILLINOIS - Generally light.

Percent infested plants by district: West-southwest 5-40, central 12.5, north-
west 15, and west 25. (Ill. Ins. Rpt.). WISCONSIN - Most larvae in second
instar in southern counties. (Wis. Ins. Sur.). MINNESOTA - Moths emerging

91 percent complete; moth emergence 14 percent. No eggs evident. Earliest corn
24 inches extended leaf. (Frye).

BLACK CUTWORM (Agrotis ipsilon) - ILLINOIS - Damaged waist-high corn in northern
area. Recent wet weather in many areas favors development. (Ins. Sur. Bull.).

CORN ROOTWORMS (Diabrotica spp.) - MINNESOTA - Hatch observed in southwest, south-
central, southeast, and central districts. First instar counts very low. Numerous
larvae on volunteer corn in soybeans reported in Houston County. Hatch late as

= 60% - =

D. virgifera - one first instar, 12 second instars, 32 third instars, 4 prepupae.
D. undecimpunctata howardi - 5 second instars, 2 prepupae. D. longicornis - 2
‘each, second and third instars. (Gunderson). NEBRASKA - Feeding by D. virgifera
and D. longicornis extensive on early planted corn. Larvae up to full grown.
Ranged 10-20 per plant at Mead, Saunders County. First adults expected about

July 4. Some lodging evident. (Munson). KANSAS - First D. virgifera adult

of season in Riley County cornfield. (Wilde). Larvae 12-25 per plant. (Simpson).
ILLINOIS - D. virgifera and D. longicornis averaged 30 per plant in some fields

common in problem fields within week or two. (Ins. Sur. Bull.).

NORTHERN CORN ROOTWORM (Diabrotica longicornis) - WISCONSIN - Larvae ranged secona
to fourth instar in Rock County. Counts low at most sites but numbers moderate
even in treated fields. Populations have shown general increase; in some instances,
numbers near point to warrant further control. Corn in many fields checked
advanced to point that further chemical application no longer feasible with
conventional equipment. (Wis. Ins. Sur.). ILLINOIS - Larval average per plant by
district: Central 0.5, northwest 2.25, and west 8. (Ill. Ins. Rpt.). OHIO -
Hatch expected soon. (Rose).

INSECT DETECTION

RICE PENTATOMID BUG (Scotinophara lurida (Burm.)) - CALIFORNIA - Collected from
crate containing lifeboats and radio equipment at McClellan Air Force Base,
Sacramento County, May 29, 1968, by J.C. Shearer. Det. by G.T. Okumura. Con-
firmed by R.C. Froeschner. Possible introduction of this serious pest occurred
when wooden crate from Vietnam was opened. Live insects were observed; the crate
was closed and treated. As precautionary measure, intensive cooperative survey,
including light trapping, was conducted and area for 0.25 mile around crate was
sprayed or charred with flame thrower by State and Federal personnel. Seven dead

specimens recovered from crate after treatment. (Cal. Coop. Rpt.). S. lurida is
a major pest of rice in areas of Japan, China, and Ceylon. The bug's feeding
causes localized, chlorotic leaf lesions on rice. Lesions gradually dry up and

frequently result in death of that portion of the leaf between the lesion and the
leaf tip, death of the central shoot, or death of the entire plant. In Japan,
early planted rice varieties are most heavily infested and densely planted fields
are preferred. S. lurida is recorded on rice and related grasses and is known to
occur in Ceylon, southern China, Formosa, Indochina, Japan, Loochoo Islands,
Malaya, Okinawa, and Thailand. Adults or late nymphs aestivate between rice crops
in cracks in the bunds in rice fields or on adjacent higher ground. Adults leave
aestivation sites in April and May or November and December, depending on planting,
and settle on the crop when it is 2 or 3 weeks old. Activity occurs largely at
dusk or at night. For additional details see CEIR 11(20) :413-414, May 19, 1961.

3 inches at a few stations in Texas, Oklahoma, and Arkansas on Monday, July 1.

As the front advanced southward and eastward, it produced generous rains in the
Gulf States on Tuesday and from southern Alabama to New England on Wednesday.

Over the weekend, hot humid southeasterly winds from the Gulf of Mexico produced
locally heavy rains over the southwestern deserts and a few areas along the Rio
Grande. Flooding occurred in the El Paso, Texas, area, Northeastern Nebraska

and. spots in Iowa also received beneficial weekend rains. Wide areas in California
and the Great Basin and numerous spots on the Great Plains recorded no precipitation

New State Records for a Lace Bug (Dictyla echii)
E.J. Hambleton

An Old World species of lace bug, Dictyla echii (Schrank), first recorded in the
Western Hemisphere in 1962 (Coop. Econ. Ins. Rpt. 12(28):778), now appears to be
well established in eastern United States. Recent collecting by the writer
revealed the presence of this species in considerable abundance in the tristate
area of Virginia, West Virginia, and Maryland. Two males and 13 females were
first collected on several scattered specimens of vipers-bugloss, Echium vulgare
L. (Boraginaceae), near Purcellville, Loudoun County, Virginia, on June 5, 1966.
On July 2, 1968, several hundred additional specimens were collected north of
Berryville, Clarke County, Virginia; near Rippon and Harpers Ferry, Jefferson
County, West Virginia; at Petersville, Frederick County, and Seneca, Montgomery
County, Maryland. These collections have been deposited in the U.S. National
Museum.

Determination of the species was made by Dr. Richard C. Froeschner, U.S. National
Museum, Washington, D.C. Although the Drake collection contained no specimens of
Dictyla echii from the United States, a single specimen was found in the National
Museum collection taken at Miami, Florida, June 15, 1944, by Willis Wirth,
Entomology Research Division, U.S. Department of Agriculture. Edward U. Balsbaugh,
Jr., Bureau of Plant Industry, Harrisburg, Pennsylvania, had also submitted for
identification four specimens collected by G.D. Sleesman: A male and female from
Devonshire, Pennsylvania, July 25, 1958; one female, Clarks Valley, Pennsylvania,
May 22, 1959, and one female; Harrisburg, Pennsylvania, June 17, 1959. This U.S..
material, all identified by the late Carl J. Drake, came to hand too late to be
recorded in "Lacebugs of the World" by Drake and F.A. Ruhoff published in 1965.

Dictyla echii, described by Schrank in 1781 as Cimex clavicornis, has been known
under various names in the Old World and for over a hundred years as Monanthia
echii. In 1960 Drake and Ruhoff referred it to the genus Dictyla Stal. The
species is widely distributed in 43 countries of Europe, Asia, and the Middle
East and North Africa. It occurrs on 14 host plants, 5 of which have been
naturalized in the United States from Europe. Echium vulgare, the only known
host from which this lace bug has been collected in the United States, is also of
European origin. Sometimes called blueweed, this biennial plant is found from
June to September usually in poor soil along roadsides, in waste places, and in
meadows and pastures from Maine to Virginia and west to Nebraska. It has erect
growth, measures from 1 to 24 feet in height, and bears bristly, hairy stems

and leaves. The flowers, borne on spikes, are pinkish-blue to violet in color,
the leaves lance-shaped and stemless.

WEATHER BUREAU'S 30-DAY OUTLOOK
MID-JULY TO MID-AUGUST 1968

The Weather Bureau's 30-day outlook is for temperatures to average above seasonal
normals in the Northeast as well as over most of the northern and central Plains
and the Great Basin. Below normal temperatures are indicated for the north
Pacific coast and also for the southern Plateau, the southern Plains, and the west.
gulf coast region. Elsewhere near normal temperatures are in prospect. Precipi-
tation is expected to exceed normal in the North and South Atlantic Coast States,
the north Pacific coast, and from the southern Plateau eastward to the west gulf
coast region. Subnormal precipitation is indicated for the Middle Atlantic

Coast States, central portions of the Appalachians, and the northern Plains,

while little or no rainfall is expected over California. In unspecified areas
near normal rainfall is anticipated.

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 JULY 15

HIGHLIGHTS: Typical July weather prevailed over most of the Nation - hot humid
with spotty afternoon and evening thundershowers, mostly light to moderate, a
few very heavy.

PRECIPITATION: Showers and thunderstorms occurred along the leading edge of a
cold front that, early in the week, extended from Missouri to New England and in
the hot humid air south of the front. Heavy rains fell in the first half of the
week over parts of the South Atlantic and Gulf States. Showers in eastern
Mississippi began on Monday and by 7 a.m. Tuesday, 15.68 inches had fallen at
Columbus. Generous thundershowers occurred over the Great Lakes region, the Ohio
River Valley, and in parts of the Northeast on Tuesday and Wednesday. A severe
thunderstorm at Auburn, New York, on Tuesday evening was accompanied by strong
winds which blew down a circus tent injuring many persons. The thunderstorms in
the Carolinas and Virginia increased in intensity from Tuesday to Thursday but
were generally lighter over the weekend. Numerous drought relieving showers in
Florida, some locally heavy, became lighter during the latter half of the week.
Weather of the Week continued on page 682.

infestation 75 percent in untreated early whorl plants; controls in progress,
Fresh egg mass found and occasional moths still active. Some males trapped nearly
every night at Poughkeepsie and Hurley. Most larvae survived treatments inside
plants, only occasional larvae found dead. Two earliest-sown varieties in mid-
silk stage by first week of July. Worst infestation in years due partly to

prolonged hatch during the month of June. Activity continues heavy in Monroe
County. (N.Y. Wkly. Rpt.). NEW JERSEY - Second and third instars infested 50
percent of sweet corn tassels near Trenton. (Ins.-Dis. Newsltr.). MARYLAND -

widespread or as severe in Giles, Bland, and Wythe Counties. Worst year for this
species in past 20 years, according to one observer. (Allen). ALABAMA - First-
generation larval damage serious in several localized cornfields in tassel stage
in Blount and Madison Counties; 1-5 pupae common, numerous moths in flight, and

egg laying underway. (Conway et al.). INDIANA - First-generation infestations |
10-100 (average 20) percent in south-central district; earliest fields (1-5 per-
cent of total) most heavily infested; fourth instars predominant. Infestations

Moderate in cornfields in 7 counties; 5-50 percent of knee-high plants infested.
Total of 60 percent of larvae second instars and 40 percent first instars. Egg
laying greatly decreased, but will continue another 10-14 days. This will
lengthen second-brood activity and its associated problems. (Newman, July 8).

ILLINOIS - Infested plants ranged 0-10 (average 2.2) per 100 plants in southeast
district and 0-6 (average 1.0) in southwest district; pupation almost 100 per-

almost complete in southernmost counties; moth emergence begun. Pupation ranged
10-40 percent in field corn in south-central area; moth emergence will begin in
late July. First-generation larvae ranged 25-90 per 100 plants in most mature
fields in area between U.S. Highways 40 and 50. (Ins. Sur. Bull.). WISCONSIN -
Mostly third and fourth instars; some tassel tunneling underway; many tunneling
in midribs. Populations generally low, but controls applied to some canning
corn. (Wis. Ins. Sur.). MINNESOTA - Egg masses generally light in third of
cornfields in southwest, south-central, and west-central districts July 2-8; 8 egg
masses per 100 plants highest count. Hatch light in all districts, but should
increase this week. Most egg laying on corn 24+ inches high. Egg masses and
larvae very difficult to find in southeast and central districts. Moth emergence
and egg laying currently continue; counts in all districts low. Heaviest

- 664 -

infestations so far have been 16 infested plants per 100; first instars 1-6 per

Pottawatomie Counties. (Simpson).

SOUTHWESTERN CORN BORER (Diatraea grandiosella) - ILLINOIS - Infested plants ranged
0-52 (average 14) per 1,000 plants in southeast district and 0-52 (average 10) in
southwest district. (Ill. Ins. Rpt.). First-generation larvae 10-30 per 1,000
cornstalks in 4 southernmost counties; infestation probably highest ever in State.
First-generation pupation begun. Some moth emergence expected within next week.
(Ins. Sur. Bull.). ALABAMA - First-generation larvae pupated in some fields in
Lawrence, Blount, and other northern counties. Flights heavy in 10-acre field

Weather of the Week continued from page 660.

Spotty showers fell in the central Great Plains almost daily. In general, they
were light and widely scattered in the first half of the week but more numerous
and heavier in the latter half. This was the second week in the Texas High Plains
and Trans-Pecos with locally heavy showers. A few localities west of Lubbock
received 3 to 4-inch showers. Showers fell in the Sierras and the desert in
California early in the week and near the end of the week in western Washington
and northwestern Oregon. Many western areas and a few widely scattered areas in
the Central and East received no rain or only light sprinkles.

TEMPERATURE: The heat over the West increased until maximums in the 90's
prevailed from border to border. Temperatures exceeding 100° were common in the
southwestern deserts with some localities registering 110° to 116° on a few days.
Miles City, Montana, registered 110° on Wednesday and Lewiston, Idaho, 105° on
Thursday. Cooler weather prevailed in the East early in the week with afternoon
temperatures ranging from the 70's in New England to the middle and upper 80's in
Georgia, to 91° at Orlando, Florida, on Thursday. A southerly flow behind a
large high pressure area brought warmer temperatures to the East late in the
week. By Sunday afternoon, maximums had increased to the high 80's and low 90's
from Florida to western New England. Albany, Buffalo, and Rochester, New York,
registered 91° on Sunday afternoon. High humidity made the warm afternoon more
uncomfortable. Cooler weather came to the Far Northwest late in the week when
afternoon temperatures in western Montana remained in the 60's and 70's

The Spotted Mediterranean Cockroach, Ectobius pallidus (Olivier)
(Dictyoptera, Blattaria, Blattellidae), in the United States

Ashley B. Gurney aly,

This European cockroach was first found established in the United States in 1948,
when outdoor collections at East Falmouth, Massachusetts, were reported (1). The
spread of this insect has been slow, and until recently it was not known to ex-
tend beyond eastern Massachusetts, but in 1967 it was found in Michigan (7). In
order that entomologists may be familiar with the recognition characters, distri-
bution, and importance of the species, this note has been prepared. The names
Ectobius livens (Turton) and E. lividus (F.) were used in early reports of the
Species in the United States (1, 2), but investigation of synonymy led to the
adoption of Ectobius pallidus (Olivier). The common name has been adopted by the
Entomological Society of America.

Ectobius pallidus (fig. 1) is a small species, about 8 to 9 mm. in overall length,
including folded front wings (tegmina). General color is light yellow. Numerous
small dark brown spots are conspicuous on the front wings and to a lesser extent
on the pronotum. The hind wing is notable for a large veinless area at the apex
known as the intercalated triangle (fig. 2, itr). Each tarsus bears 2 small
claws, the posterior one of each pair clearly longer than the anterior one (fig. d
3). The terminal ventral segment of the adult male abdomen bears a single stylus ©
(fig. 4, st). A more detailed description was published in 1953 (2).

This species has been collected in 10 towns within 3 counties of eastern Massa-
chusetts: Middlesex (Natick, Sherborn); Plymouth (Duxbury, Manomet, Plymouth) ;
and Barnstable (Cotuit, Falmouth, East Falmouth, Osterville, West Yarmouth); the
most distant of these towns (Sherborn, West Yarmouth) are about 65 miles apart.
The two Michigan localities are Bloomfield Hills (Oakland County, about 20 miles
north of Detroit), and Detroit.

Abroad, Ectobius pallidus occurs in southern England, Germany, Belgium, France,
Italy, Spain, and Portugal (3), as well as in Algeria and Tunisia in North Africa.
Among European populations of pallidus, two subspecies and a variety are based on
color differences (3). The small dark brown spots on the front wings are less
conspicuous in English specimens than in American ones or those from some conti-
nental European areas; and it seems probable that the stock leading to the estab-
lishment of the species in the United States originated in Portugal or elsewhere
in southern Europe. The large number of people of Portuguese ancestry living in
the Cape Cod area of Massachusetts, where the first established colonies were
found, and their frequent contacts with Portugal, suggest that country as a pos-
sible source.

E. pallidus is primarily an outdoor species, living in a variety of field habitats
(2, p. 44). Roth and Willis (6) found it at Plymouth, Massachusetts, "numerous
under leaf litter in shaded woods." At East Falmouth, Massachusetts, Flint (1)
found pallidus active at night running about on trunks of oak trees but in the day
hiding under loose lichens and bark, in the bases of Swiss chard plants, under
boxes and baskets, and in other outdoor situations. Of its occurrence in southern
England, Ragge (4, p. 74) says "Though perhaps most frequently occurring in wood-
land [it] may also be found on heaths, downland and even sand-dunes. In warm
weather, when this insect flies readily, it often occurs on bushes or trees."

At least three houses in the United States are known to have become infested by
E. pallidus. One of the infested houses in Massachusetts was a cottage ina
wooded area with underbrush close by; the cottage was said to be overrun by the
cockroaches, which even hid beneath shingles of the roof. The Bloomfield Hills,
Michigan, colony clustered on the bark of an oak tree in the yard of a house.
The cockroaches accumulated on outside brick walls and around basement windows,
and.some individuals squeezed through small openings and entered the house. No
details of the Detroit colony are available, though apparently it was large
enough to suggest several years' development.

The biology of Ectobius pallidus is not known fully, but it appears that there
are five to six nymphal Stages and that overwintering occurs primarily in the egg
stage, also probably in part as nymphs. A dormant period or diapause for eggs
prior to hatching seems necessary, and moisture is required for the swelling and
final development of the eggs (6). Egg cases (odthecae) have been illustrated by
Roth (5, figs. 147, 148). Adults appear early in summer and die by late fall or
early winter.

This cockroach is unlikely to become an important pest, but gradual spread in
this country and occasional instances of indoor infestation are to be expected.

CITRUS

Quarterly Citrus Insect and Mite Outlook in Florida - July through September -
This outlook is based on the assumption that weather beyond the period of the
current U.S, Weather Bureau 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 "Insect and Disease Summary" usually released twice each month by this station,

CITRUS RUST MITE (Phyllocoptruta oleivora) expected to be in moderate to high

range until mid-August, about normal for period. Will decrease to low level from
mid-August to mid-September, Will heavily infest fruit in 15 to 20 percent of
groves. TEXAS CITRUS MITE (Eutetranychus banksi) and CITRUS RED MITE (Panonychus
citri) will decrease in July and hold at low level through September. Scattered
infestations may become important in young groves. BLACK SCALE (Saissetia oleae)
will remain abnormally high through July and contribute to heavy buildup of sooty
mold, Adults will diminish in August but crawlers will become numerous. High
mortality of young scales expected in September. An ARMORED SCALE (Unaspis citri).
expected to spread and intensify. GLOVER SCALE (Lepidosaphes gloverii), PURPLE
SCALE (L. beckii) , CHAFF SCALE (Parlatoria pergandii), and YELLOW SCALE (Aonidiella
citrina) expected to be at or below normal abundance and to decrease through
September. MEALYBUGS will persist in moderate numbers until August and contribute
to sooty mold buildup, then drop to low level. WHITEFLIES will decrease through
August, increase in September, Nymphs will be in moderate numbers throughout
period and add to sooty mold buildup. (W.A, Simanton).

WEATHER OF THE WEEK ENDING JULY 22

HIGHLIGHTS; Typical summer weather continued over most of the Nation -- hot and
humid with widely scattered heavy thunderstorms. Temperatures in the East
returned to comfortable levels over the weekend,

PRECIPITATION: Scattered thundershowers occurred from the Rocky Mountains to the
Atlantic coast being especially numerous and heavy early in the week from the
central Great Plains to the Ohio River Valley. Heavy downpours hit northeastern
Kansas and southeastern Nebraska late Monday and early Tuesday with some spots
receiving 6 to 9 inches of rain. Torrential rains fell in northeastern Iowa when
many stations recorded totals ranging from 5 to nearly 15 inches. The heaviest
amounts fell in the Waterloo area. Strasburg, Ohio, registered 3.40 inches in 1
hour on Tuesday. On Wednesday, tornadoes touched down and numerous funnel clouds
were seen at scattered localities from Kansas to Wisconsin, Convective showers
occurred almost daily from Alabama to New England in the hot humid air mass that
lay over the East. Amounts ranged widely from light sprinkles to over 3 inches
with widely scattered spots receiving larger totals. Scattered thunderstorms
occurred in New England on the 17th and 19th, some being accompanied by damaging
lightning, wind, and soil-washing rains, The cold front passage provided a rain-
less weekend in the East. Widely scattered showers continued in the Deep South,
however. A vigorous system moved into the Far Northwest on the 19th, accompanied
by strong gusty winds. In general, very little rain fell from the Pacific Ocean
to the western edge of the Great Plains. California, Nevada, and southern Oregon
received no significant rain during the week,

TEMPERATURE: Hot humid weather continued over the eastern half of the Nation

@arly in the week as moist tropical air moved northward from the Gulf of Mexico
behind a warm stationary dome of high pressure. Afternoon temperatures soared to
the 90's on several days. Waltham, Massachusetts, registered 100° ‘on Tuesday
afternoon when temperatures in portions of the Great Plains reached 100° or

higher; 110° at Healy, Kansas. Temperatures over Lower Michigan ranged from the
70's in the early morning to the 90's on several afternoons. After about a week

of the torrid temperatures, a cold front passage brought a delightfully comfort-
able weekend to the East. Temperatures averaged below normal from Washington and
Oregon to the western edge of the Great Plains and from New Mexico to the Carolinas
and above normal over the rest of the Nation, The Great Lakes region and the
Northeast averaged 4° to 8° warmer than normal, (Summary supplied by Environmental
Data Service, ESSA,)

HAWAII INSECT REPORT

New State Record - Severe infestation of BEAN FLY (Melanagromyza phaseoli (Tryon) )
Tarvae and pupae found on snap bean stems at Waiahole, Oahu, on June 19, 1968;

at Kapaa June 21 and Wailua July 15 on Kauai. Found by G. Funasaki and B.

Kumabe. Adults reared from specimens collected at Waiahole and Kapaa determined
by G.C. Steyskal. This insect is well known and serious pest of snap beans and
and important pest of lima beans, soybeans, and cowpeas. Distribution includes
Egypt and several countries south of the Equator in Africa as well as eastern
India, Burma, Malaysia, Ceylon, Singapore, Indonesia, New Guinea, China, the Phil-
ippines, Mauritius, Malagasy Republic, Australia, New Zealand, Guam, and Samoa.
(Funasaki). M. phaseoli frequently causes total loss of the bean crop in numerous
tropical and Subtropical countries. The pest is largely responsible for
restricting the bean-growing season in Australia to the cooler months and may

even cause serious losses if the winter is mild. This fly is the most important
pest of beans in New South Wales. Up to 100 percent infestation has been recorded
in Kenya and Tanzania with resultant losses of 50-100 percent. Soybeans are
severely damaged in China and Java. Large reductions in stands of cowpeas have
been reported from Ceylon. Nightshade, chick peas, Dolichos sp., and crotolaria
are also reported hosts. This is a new Western Hemisphere record. M. phaseoli

is not known to occur in the continental United States. For additional details

see CEIR 7(37):751-752, September 13, 1957. (PPC).

General Vegetables - LEAF MINER FLIES (Liriomyza spp.), CARMINE SPIDER MITE
(Tetranychus telarius), and GREENHOUSE WHITEFLY (Trialeurodes vaporariorum)
continue problem on Snap beans throughout Oahu despite intensive Spray operations.
One or more of these pests also heavy on eggplant, watermelon, tomato, cucumber,
daikon, mustard cabbage, bittermelon, and yard-long beans. (Sato et al.).
SOUTHERN GREEN STINK BUG (Nezara viridula) nymphs and adults caused moderate to
heavy damage to orchid flower buds in Wailuku, Maui. Adults heavy on vegetable
crops up to 4,000 feet elevation in Kula. Nymphs and adults light on crops but
generally medium on some weeds in Waianae and Ewa, Oahu; light in other farming
areas on island. (Miyahira, Funasaki). BEET ARMYWORM (Spodoptera exigua) and
leaf miner flies generally medium in green onion fields at Koko Head and
Waimanalo, Oahu. Damage by leaf miner flies not so serious as in summer of 1967.
(Funasaki).

Fruits - Single specimen of CLOUDY-WINGED WHITEFLY (Dialeurodes citrifolii) found
on citrus leaf in Kailua, Oahu. Det. by L.M. Russell. Leaf heavily infested
with GIFFARD WHITEFLY (Bemisia giffardi). D. citrifolii first found in State on
citrus in March 1966 at Hilo, Hawaii. (Shiroma). Additional specimens of a
STINK BUG (Plautia stali) collected on Oahu; 3 adults taken from guava fruits in
Palolo area of Honolulu and 1 adult at light at Koko Head. (Wong, Mitchell).

Beneficial Insects - LANTANA HISPID (Uroplata girardi) larvae, pupae, and adults
very heavy on lantana in pasture at Ulupalakua, Maui. Up to 75 percent of leaves
damaged in some areas. (Ah Sam). Adults of a DUNG BEETLE (Onthophagus catta)
heavy in cow dung in pasture at Ulupalakua, Maui. (Miyahira).

INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES

QUETTA BORER (Aeolesthes sarta (Solsky) )

Economic Importance: This major pest of fruit also severely damages forest and
ornamental trees. Heavy injury has been observed in Afghanistan and serious
damage to birch was caused in 1939-1940 in Uzbekistan, USSR, In Quetta and other
areas of West Pakistan, trees on many of the streets have been killed. Holes and
small rotting areas on the bark of the main trunk and large branches indicate
damage by the Quetta borer. Large parts of the attacked areas eventually fall
off. As a result of larval feeding into the bast and sapwood, the sap flow is
cut off before it reaches the crown and the tree dies. The galleries and tunnels
cause a drying out of the stem and branches so that they break off easily in the
wind. Trees are often killed in 2-4 years.

Distribution: Afghanistan, China (mainland--Western Tibet), India (Kashmir) ,
Iran (southeastern), Pakistan (West), USSR (southeastern area including Kazaka-
stan, Uzbekistan). Found usually in the lower mountainous areas,

Hosts: Almond, apple, apricots, peach, quince, walnut, elm, poplars, willows,
and other trees.

General Distribution of Aeolesthes sarta (Solsky)

Life History and Habits: Under West Pakistan conditions, the biology is as
follows: In May females deposit eggs in groups of 5-10 inside wounds in the
bark, pits of stems or broken ends of branches of living trees. One female may
lay about 50 eggs which hatch in 10-14 days. At first, the larva feeds on soft
bark but later bores into the sapwood where it starts a gallery. During the
summer and fall, the larva enlarges the gallery but during the winter it chews
out the tunnel. The pupal chamber is constructed the following spring. Pupation
requires about 4-5 months but adults remain in the pupal chamber several months
until the exoskeleton hardens. Adults appear in May and are numerous in June but
decline in July and August. Oviposition occurs about 10 days following mating.
The life cycle requires two years.

Coleoptera: Cerambycidae No. 178 of Series

Description: ADULT - Length 33-44 mm. Elongate, cylindrical; brown, with grayish
pubescence. Patches on elytra with a silvery luster; many other species of genus
with a gold or coppery luster. Elytra obliquely truncate at apex. Antennae of
male twice or more the length of the body. Antennae of female not as long as the
body. LARVA - Length about 6 mm. in the first stage but nearly 80 mm. long when
full grown. Yellowish and about 15 mm. in diameter when full grown.

WEATHER OF THE WEEK ENDING JULY 29

HIGHLIGHTS: Precipitation totals ranged widely due to heavy isolated showers.
The hot humid weather in the East was followed by a cool sunny, pleasant weekend,

PRECIPITATION: Generous Showers occurred early in the week along a front that
stretched from the central Rockies to New England; also in the warm moist air
along the gulf and from the Dakotas to the Great Lakes in the warm air overrunning
the front. Heavy rains in Iowa -- over 2 inches in 6 hours caused extensive
flooding along small creeks on Tuesday. Hickman, Nebraska, received 7 inches in

3 hours on Tuesday afternoon which also caused considerable flooding. Beneficial

rains fell in Arizona Tuesday -- 3.57 inches at Prescott. Chicago, after 3 weeks
of dry weather, received 3-1/2 inches of rain Tuesday p.m, and Wednesday a.m.
Heavy rains along Rock Creek -- 8.55 inches at Westmoreland, Kansas -- flooded

3/4 of the town of Louisville, about 15 miles downstream, Five to 6-inch rains
soaked other spots in east-central Kansas Tuesday evening and Wednesday morning
and more heavy rain fell in extreme east-central Kansas and west-central Missouri
on Wednesday evening and Thursday morning. Many spots in the Kansas City vicinity
received 3- to 7-inch totals. Rainfall totals ranged widely over much of the
East with isolated showers dumping amounts much larger than the averages for the
areas. The Great Lakes region received their rains mostly during the first half
of the week. In New England the scattered thundershowers occurred at midweek and
on Sunday. In parts of the Deep South, the shower activity increased in the last
half of the week. Precipitation was mostly light west of the Continental Divide.
Wide areas in the Northwest received no rain. In California, only the deserts
and the southern coast received sprinkles.

heavier generally in small fields where weevils overwintered nearby. (McQueen).
TENNESSEE - Still between generations. Some first-generation weevils in early
cotton feeding mostly on blooms and squares; some punctured squares due to egg
laying. Punctured squares averaged 14 percent in treated and untreated fields

in regularly infested portion of cotton-growing area. Rain over area should
cause infestations to vary widely from locality to locality and, in some cases,
from field to field. Dry weather caused much mortality of first-generation
weevils. More control noted in 1968 than in last 15 years. (Locke). MISSIS-
SIPPI - Remains lower than normal in much of State. Increased this week; second-
generation emergence begun during first part of week in south delta area.

observed. Egg counts remained generally low. Eggs increased, 6 per 100 terminals
in most fields in Yazoo County; 12 per 100 terminals in one field. Larval average
per 100 terminals by county: Hinds, 3 in 2 fields; Union, 3 in 12; Sharkey, 1 in
30; Montgomery, 4 in 56; Issaquena, 2 in 18; Holmes, 1 in 15 fields. (Dinkins).
H, zea damaged some squares in delta counties; very few eggs and larvae. Flight
increased some, but still low for time of year. (Pfrimmer et al.). ARKANSAS -

Weather of the week continued from page 720.

TEMPERATURE: Pleasant summer weather continued across much of the Nation, Early
morning temperatures ranged from the 50's along the Canadian border to the 90's
over the southern half of the Country. Portions of Kansas and Oklahoma registered
100° or higher on a few days early in the week -- 104° at Russell, Kansas, on
Tuesday. Such temperatures occurred almost daily in the southwestern deserts --
108° at Blythe, California, on Wednesday. Skies were mostly sunny except along
the front that stretched from the Colorado Rockies to the Northeast in the warm
moist air overrunning the front, and along the gulf where afternoon cumuli form-
ed. High pressure moved into the East late in the week bringing a sunny cool
pleasant weekend, Weekly mean temperatures averaged near normal over most of the
Nation. The two main exceptions were the Dakotas which averaged 6” to 8° cooler
than normal and eastern Oregon which averaged several degrees warmer than normal,

HOUSEHOLDS AND STRUCTURES

A POWDER-POST BEETLE Cainthes rugicollis (Walker)) - FLORIDA - Found in oak floor-
ing in new home at Coral Gables, Dade County. Collected by A.L. Humphries and

J.L. Weaver May 6, 1968. pat. by R.E. Woodruff. Confirmed by E.J. Gerberg. This
is the first report of an established infestation of this insect in the continental
United States. Limited followup surveys have failed to find additional infesta-
tions. This lyctid has been intercepted approximately 250 times since 1928 at

U.S. ports of entry, stead in bamboo. This is the most frequently intercepted
species of the genus, rugicollis is apparently tropicopolitan in distribution.
It is known to occur ok the Indomalaya region to Madagascar as well as the
Antilles, Congo (Kinshasa), Dahomey, Guinea, Hawaii, India, the Indochina region,
Ivory Coast, and New Caledonia. (PPC) .

districts. (Huber). SI a SSR mea

BIG-EYED BUGS (Geocoris spp.) - OREGON - Mostly Geocoris sp. adults averaged 2
per sweep in Wasco County alfalfa field. (Brown). ARKANSAS - G. punctipes
principal predator on heads of maturing sunflower in Jackson and Lee Counties;

HONEY BEE (Apis mellifera) - ALABAMA - Colonies in State declined further in 1968;
July 1 total placed at 91,000; 5 percent below 1967. Numbers steadily declined
since 1956. Condition of bee colonies reported at 84 percent (off slightly from
85 percent of July 1, 1967) and 4 points below average. Condition of nectar
plants 71 percent of normal compared with 75 percent in 1967; low condition re-
flects effects of June drought. Condition of nectar plants improved during July
since most areas received moisture. (Strong, Brisco). GEORGIA - Above average
sourwood honey crop being produced in mountains in 1968. (Coleman). OHIO -
Total of 146,000 colonies on hand in State July 1, 1968, represents 2 percent
reduction from 1967. Some reduction due to heavy rains in late May. Condition of
colonies 83 percent July 1 compared with 76 percent July 1, 1967; below 5-year
average of 86 percent. Most colonies wintered well and early spring prospects
good for honey production after favorable weather in April. Heavy rains in late
May plus repeat of excessive swarming of 1967 lowered these early prospects
slightly. (Kenney, Tucker).

WEATHER BUREAU'S 30-DAY OUTLOOK
AUGUST 1968

The Weather Bureau's 30-day outlook calls for temperatures to average below
seasonal normals from the Continental Divide eastward to the Ohio and lower
Mississippi Valleys. Above normal temperatures are indicated over most areas

west of the Continental Divide except for below normal temperatures along the
California coast and also over the southern Plateau. Near normal temperatures

are in prospect over much of the East. Precipitation is expected to exceed normal
over much of the Midwest, southern Plains, and in the Far Southwest. Subnormal
amounts are anticipated over the Pacific Northwest. In unspecified areas near
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.

WEATHER OF THE WEEK ENDING AUGUST 5

HIGHLIGHTS - Temperatures ranged widely over the northern and central Great Plains
but were fairly uniform in the West and South. Precipitation was extremely spotty.

PRECIPITATION: Showery weather left an uneven precipitation pattern over most
States. Many States received light to moderate showers with a few heavy downpours
and some areas which received no rain or only light sprinkles. This is well
illustrated by the showery pattern in the central Great Plains. No rain or only
light sprinkles fell in parts of the Sand Hills in’Nebraska but some southeastern
counties received generous thundershowers,some accompanied by damaging winds

and hail. Similarly, a few stations in south-central Kansas received no rain

but flash flooding occurred along small streams in the northeast due to spotty
showers which dumped more than 4 inches of rain in short time intervals. The

Same general pattern prevailed from the Dakotas to New England in the North and
from Arizona to the Carolinas in the South. Heavy thundershowers drenched the
Arizona and Utah border on Thursday. More than 3.5 inches at Monticello and
almost 4.5 inches at Blanding, Utah, on Thursday caused flooding on the San Juan
River. Much of Washington, northern Idaho, and the coastal areas of California
and parts of southern Texas received no rain. The scattered afternoon and

evening thundershowers replenished soil moisture in many areas but some spots
missed by the rains continued very dry.

TEMPERATURE: Temperatures averaged above normal over parts of the Far West;

also from the mouth of the Mississippi River along the gulf coast and northward
along the Atlantic coast to New Jersey and below normal over most of the interior
of the Nation. Parts of the central Great Plains averaged 4° to 7° cooler than
normal. Afternoon temperatures in the Far West reached 90° or higher on most

days and 100° on a few days. Maximums of 100° or warmer were common in the south-
western deserts on every afternoon. Along the gulf, afternoon temperatures

climbed regularly into the 90's. The largest temperature variations occurred in
the northern and central Great Plains. To illustrate: Russell, Kansas, registered
104° Tuesday but only 74° Wednesday afternoon, 78° on Friday, and 101° on Saturday.
At Williston, North Dakota, the temperature reached 98° on Monday afternoon but
only 69° on Tuesday. By Sunday, most of North Dakota experienced 91°-96° maximums.
In the Northeast, the week began cool and comfortable but became hot and humid by
the weekend. (Summary supplied by Environmental Data Service, ESSA.)

WEATHER OF THE WEEK ENDING AUGUST 12

HIGHLIGHTS: The Far West continued warm and dry. A cold front brought a pleasant
weekend to the Central and East following several days of unusually hot humid
weather.

PRECIPITATION: Heavy rains fell early in the week along a front that extended
across our northern border States from the western Great Plains to New England,
Numerous tornadoes and violent thunderstorms occurred from South Dakota and Iowa to
Lower Michigan. Most of the tornadoes struck rural areas, A few farmsteads
suffered damage to buildings and trees. Besides the heavy showers that accompanied
the violent thunderstorms and tornadoes along the front, airmass thunderstorms
developed in the hot,humid air south of the front. The Showers were mostly light
producing an inch or less of rain. In some areas, rainfall ranged from 1 to 2
inches and widely scattered storms dropped several inches in short time intervals.
On Thursday, a severe thunderstorm at Burlington, Vermont, dropped hail up to 3
inches in diameter and the wind at Blue Hill Observatory, Milton, Massachusetts,
gusted to 90 m.p.h. Heavy downpours fell Friday night in southeastern Nebraska,
eastern Kansas, southwestern Missouri, and northern Arkansas with spots recording

4 to 5 inches of rain by Saturday morning. Little or no rain fell in the Far West.
Forest fire danger increased in Washington and lightning started hundreds of fires
in Oregon, Dust storms occurred in the irrigated valleys of southern Arizona,

TEMPERATURE: Through most of the week, sweltering heat and high humidity main-
tained a firm grip over most of the Nation from the Rocky Mountains to the
Atlantic coast. Cool weather occurred only along our northern border north of
the quasi-stationary front that stretched from Montana to Maine. In some eastern
areas, last week was the hottest of the season. In North Carolina, it was the
hottest week in almost 2 years. Beloit, Wisconsin, registered 100° on Thursday,
the first time in several years that the temperature has gone so high anywhere in
the State. Temperatures reached 100° to 105° on several afternoons from southern
South Dakota to northern Texas. The front began moving late in the week and by
the weekend, a broad stream of cool,dry air was bringing unseasonably cool
weather and clear skies to much of the central and eastern portions of the Country.
Numerous locations in the Northeast registered temperatures in the 40's early
Monday morning, August 12. The Far West continued warm to hot throughout the
week, The Rocky Mountains and western Plains averaged cooler than normal. Most
of the East averaged warmer than normal in spite of the weekend temperature drop.

SPECIAL INSECTS OF REGIONAL SIGNIFICANCE

GREENBUG (Schizaphis graminum (In broad sense))* - SOUTH DAKOTA - Destroyed 120
acres of sorghum-sudan crosses 2-3 inches high near Lesterville, Yankton County.
Damaged sudan and crosses of sorghum and sudan in Moody, Turner, Yankton, and
Hutchinson Counties. Ranged 4,500-5,000 per plant on some sorghum. Killed
several fields of sorghum and sorghum crosses near Parkston, Hutchinson County.
Predators light in those fields surveyed. (Jones, Kantack). NEBRASKA - Infesta-
tions declined sharply in eastern area due to parasitism. Parasites destroyed up
to 95 percent of aphids in 2 Saunders County fields August 6. (Roselle). Still
high on untreated sorghum near North Platte, Lincoln County; ranged 1,600-2,300
per leaf August 8. Predators and parasites increasing slowly. (Staetz). KANSAS -
Infesting most sorghum fields throughout State. Damaging numbers in many fields;
up to 2,000 per leaf. Severely damaging late-planted fields. In most areas,
populations continue to increase except in occasional heavily infested fields
where predators and parasites established. Parasitism ranged 25-50 percent in
one heavily infested field in Pottawatomie County. (Brooks et al.). OKLAHOMA -
Continues heavy in sorghum in Texas, Cimarron, and Beaver Counties. Counts range
1,500-5,000 per plant on leaves, up to 50 per head on plants with heads. Many
fields being sprayed. Young sorghum plants and volunteer small grain plants killed
in many areas, Also reported causing severe damage to broomcorn in Cimarron County.
High counts also reported from Harper, Woodward, Ellis, Beckham, Washita, Blaine,
Jackson, and Marshall Counties, Parasites and predators active in west-central
and southwest areas and in Payne County; appear to be causing some decrease in
numbers, Survey shows only occasional fields lightly infested in Noble, Kay, and
Grant Counties. (Okla. Coop. Sur.). ARIZONA - Unidentified aphid generally heavy
on sorghum in most areas of Cochise County; controls applied. (Ariz. Coop. Sur.).
TEXAS - The aphid is a serious problem on sorghum in the Panhandle and parts of
Rolling Plains. Widespread treatment is being carried out. (Green). Normally,
greenbug does not cause serious damage to sorghum in this country. The aphid
generally does not reproduce after temperatures reach 90° or higher. However,
infestations in this outbreak became worse between June and the latter part of
July. USDA and State officials will meet at Fort Collins, Colorado, August 15-

16 to discuss current and future plans to combat greenbug outbreaks on sorghum.
ARS, in cooperation with affected States, is studying the biology of the pest on
sorghum and conducting aerial insecticide tests. (ARS) For previous reports on
sorghum see notes carried under greenbug in CEIR 17(37):847, 18(22):461, 18(23):
485, 18(24):509, 18(26):573, and 18(31):722. (PPC).

ASTER LEAFHOPPER (Macrosteles fascifrons) - WISCONSIN - Increased in lettuce
fields at Montello; problems somewhat greater than normal but far less than at
this time in 1967. (Wis. Ins. Sur.). COLORADO - Undetected in Otero and
Pueblo County lettuce fields as of August 3; ranged 1-584 per night in light
traps last 2 weeks. (Schweissing).

BEET LEAFHOPPER (Circulifer tenellus) - WYOMING - Curly-top symptoms affected 72
of 3,200 plants in 16 sugarbeet fields in Washakie and Big Horn Counties. Adults
averaged 0-2 per 100 sweeps in 6 fields checked. (Petersen, Parshall). UTAH -
Ranged 2-5 per 10 sweeps in Russian thistle in Deseret and Delta area of Millard
County. (Knowlton, Aug. 1). COLORADO - Ranged O-5 per 100 sweeps on southeastern
area Sugarbeets. (Schweissing).

CORN EARWORM (Heliothis zea) - NEW YORK - Appeared late in 1968. First noted on
Sweet corn August 1 in Hudson Valley when 2 sixth instars found in 300 ears at
harvest in Stone Ridge; no moths trapped. (N.Y. Wkly. Rpt.). NEW JERSEY -
Adults increasing throughout State; problems on corn should increase sharply.
(Ins.-Dis. Newsltr.). DELAWARE - Adults increased in blacklight traps in Sussex
County; averaged 3-4 per night. (Burbutis). MARYLAND - No adults taken at
Centreville blacklight trap yet. Very little damage to sweet corn to date. Less
than 1 percent damage to ears in 7 acres of sweet corn near Wye Mills, Talbot
County. (U. Md., Ent. Dept.). INDIANA - Infestation less than 2 percent (very

SMALL FRUITS

BRAMBLEBERRY LEAFHOPPER (Macropsis fuscula (Zetterstedt)) - WASHINGTON - Heavy
infestation found on Rubus Sp. at two locations on McChord Air Force Base, Pierce
County, July 24, 1968. Collected and determined by S. Nakahara, Plant Quarantine
Division, ARS. Confirmed by J.P. Kramer. This is a new United States record.

An outbreak of this leafhopper was discovered on loganberry on Lulu Island, Brit-
ish Columbia,in 1952. Heavy infestations have occurred in the Lulu Island area
Since 1952 causing considerable damage to various brambleberries through feeding
on flowers and fruit and through heavy honeydew deposits,s Infestations have been
difficult to control. This insect assumed a more important economic status when
it was shown to be the vector of the destructive Rubus stunt virus of Europe in
1953. This virus is not known to occur in North America. M. fuscula infests
Rubus spp. and occurs in several countries of Europe as well as in British Colun-
bia, Canada. The insect overwinters in the egg stage in canes of wild and culti-
vated Rubus spp. Eggs hatch in late May in British Columbia, about the time
loganberries begin to blossom. Nymphs are numerous by mid-June. There are 5
instars, each stage requiring about 10 days. Adults appear in midsummer. There
is apparently only one generation a year. In the Netherlands, the virus is spread
from old to new berry plantations by adults. For additional details see CEIR 9
(12): 209-210. (PPC).

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

The Weather Bureau's 30-day outlook is for temperatures to average below normal
over the Northeast, the northern border States, and most of the country west of

the Continental Divide. Above normal temperatures will prevail over the Southeast,
while near normal temperatures are expected elsewhere in unspecified areas. Pre-
cipitation will total above normal over the southern Rockies and most of the
Plateau, the Pacific Northwest coast, and the Midwest. Subnormal amounts are
expected in southern California, New England, and the Southeast, while near normal
rainfall is in prospect elsewhere,

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 19

HIGHLIGHTS: Light rains began in the Pacific Northwest. Violent weather struck
the central Great Plains. The Southeast continued hot and humid.

PRECIPITATION: Light rains fell early in the week in the hot humid air mass that
Tay over the Deep South; also in the western mountains, On Tuesday evening

steady rain began in the Pacific Northwest bringing a welcome interruption to the
dry season and lessening the forest fire hazard in that area. Violent weather
occurred Wednesday afternoon and evening in the central Great Plains with 5 to 9
inches drenching spots in eastern Colorado. Eads, Colorado, received 6.15 inches
in 4 hours, flooding many homes, Other heavy thunderstorms occurred from Nebraska
to northern Texas and in the Ohio River Valley. Many of the thunderstorms were
accompanied by strong winds and hail. As thunderstorms continued in the tropical
air that covered the South and along the front that separated this air mass from

and Washita Counties; up to 600 per leaf in Beckham County. Moderate on sorghum
in Caddo and Marshall Counties. Ranged 0-70 per leaf in fields in Kingfisher,
Major, and Dewey Counties. Light in volunteer wheat in eastern Harper and
western Woodward Counties. Lady beetle larvae up to 15 per leaf in heavily in-
fested fields. Very heavy numbers in Panhandle decreasing; large scale
operations decreasing. (Okla. Coop. Sur.). KANSAS - Heavily infested sorghum
fields July 24 found free of live aphids August 12 in Jefferson County; many
parasitized aphids found. No live aphids in previously infested sorghum in
Atchison, Doniphan, Brown, and Jackson Counties; parasitized aphids in all
fields. Predator activity increased in Finney County, but not widespread in
western area. (Simpson). NEBRASKA - No live aphids in 3 grain sorghum fields

(Johnson, Schweissing). WYOMING - Ranged 2-100 per sorghum plant in Goshen
County. Small red patches on leaves where aphids feeding. Less than 2 per leaf
on 3 corn plants in Platte County field. More general July 26 to August 2, but
apparently declined since in cornfields. Parasites and predators increased in
sorghum and controlling this aphid. (Parshall). ARIZONA - Continues to damage
grain sorghum in Cochise, Graham, Pima, and Pinal Counties. (Ariz. Coop. Sur.).

Dis. Newsltr.). MARYLAND - First adults of season taken at Centreville black-
light trap; averaged 1 per night. Extremely light to date. Below normal infesta-
tions expected on all late-season crops. Decline attributed to heavy spring
rains during May and June. (U. Md., Ent. Dept.). SOUTH CAROLINA - Increasing

on soybeans in some counties, especially in coastal area. Larvae consumed almost
every bloom in one soybean field in Beaufort County. (Thomas, Aug. 13). Heavy

CONSIN - Earlier threat to sweet corn than expected. High blacklight trap
catches of 5 August 15 at Cobb, Iowa County, and of 3 August 13 at Arlington,
Columbia County. Nearly identical catches at these 2 separate locations may
indicate that the same situation exists in much of the sweet corn growing acreage
in area. Sweet corn protection required now. (Wis. Ins. Sur.). NEBRASKA -

New State Record - First adult of a CADDISFLyY (Hydroptila sp.) collected in. light
trap at Honolulu International Airport on Oahu May 20, 1968. Four additional
specimens taken in light traps from May to July in airport area and one caught at
U.S. Public Health Service Quarantine Station in downtown Honolulu August 5. This
is third caddisfly species reported in State and apparently undescribed. Det.

by C.R. Joyce, confirmed by O.S. Flint. (Joyce).

Corn - Probably TUMID SPIDER MITE (Tetranychus tumidus) heavy on sweet corn
throughout Waianae, Waimanalo, Waialua, and Pupukea, Oahu. Control difficult in
many cases. (Funasaki).

General Vegetables - Intensified BEAN FLY (Melanagromyza phaseoli) spray operations
continued on seedling beans in many fields on Oahu to prevent Oviposition.

Numbers heavy in Waiahole and Waimanalo. Adults and larval damage light in
Waianae, Kaaawa, Koko Head, Pupukea, and other coastal areas. (Funasaki).

LEAF MINER FLIES (Liriomyza spp.) increased considerably on green onion fields
throughout Oahu. Medium to heavy in all fields in Koko Head, Waimanalo, Waianae,
and Kahuku. Severe on tomatoes and snap beans in many fields in Waianae,

Pupukea, and windward areas on Oahu despite heavy spraying. Light to medium on
cucumbers and lima beans in Waialua and Pupukea. (Sato et aes ie

Fruits - LARGE MANGO TIP BORER (Bombotelia jocosatrix) larvae and adults trace
On mango trees in various areas on Oahu. (Funasaki).

Beneficial Insects - SOUTH AFRICAN EMEX WEEVIL (Apion antiquum), an introduced
Species, Substantially controlled emex (a noxious weed) along main highway in
Kamuela, Hawaii Island. Larvae of a CERAMBYCID BEETLE (Archlagocheirus funestus)
damaged acres of cactus in Kawaihae-uka area, South Kohala on Hawaii Island.

Many plants fell to ground; cactus less abundant in area. (Yamayoshi).

Miscellaneous Insects - Adults of a RHOPALID BUG (Jadera haematoloma) light on
weeds at Pearl City Heights; all stages heavy on balloon vine in Waipahu. All
stages of RED-SHOULDERED STINK BUG (Thyanta accerra) light to medium on grasses
in Honolulu International Airport area, Oahu. (Funasaki).

Weather of the Week continued from page 806.

the polar air that pushed into the northern States, a few tornadoes occurred at
scattered locations in the Midwest. One tornado caused widespread minor damage

in the St. Louis area, Missouri, Thursday afternoon and several tornadoes struck
Chicago's western and northern suburbs and elsewhere in northern Illinois Friday
afternoon and evening. Tornadoes and violent weather continued through most of
the night in northern Missouri, Iowa, Illinois, Wisconsin, and Michigan. The
areal distribution of weekly rainfall amounts over the United States was extremely
uneven - typical of the summer season, Many areas where the average rainfall
ranged from 0.5 to 1 inch were spotted with totals exceeding 4 inches and, as
usual, the southwestern deserts received no rain or only light sprinkles,

TEMPERATURE: In general, two kinds of weather prevailed over the United States
during the past week. A front stretching from west of the central Rockies to the
Northeast separated cool, comfortable, dry air in the North from the hot, humid,
tropical air that covered the South. Temperatures in the 90's were common along
the gulf throughout the week and on Sunday afternoon they reached 100° or higher
from central Georgia to central South Carolina. This tropical air was especially
humid. Dew points on most days exceeded 70° as far north as the Ohio River. The
front moved southward late in the week. The Northeast was much cooler by Sunday.
In general, the Southeast averaged warmer than normal and other areas averaged
cooler than normal. Much of the Great Basin and northern Great Plains averaged
8° to 12° below normal, (Summary supplied by Environmental Data Service, ESSA.)

WEATHER OF THE WEEK ENDING AUGUST 26

HIGHLIGHTS: Cool and comfortable, West and North; hot and humid Central and East,
until weekend, Stormy along front separating air masses,

PRECIPITATION: Generous rains fell in the Pacific Northwest early in the week and
in the northern Rockies at midweek, Numerous locations in Oregon and Idaho have
received more rain in August 1968 than in any previous August. Air-mass thunder-
showers occurred in the Deep South and along the Ohio River on several days during
the week, The principal precipitation, however, fell from storms along the front
that separated the cold and warm air masses, Severe weather occurred in Minnesota
and Wisconsin on Monday when a tornado leveled barns and damaged other buildings
in the Kenyon, Minnesota, vicinity and other twisters struck near Marinette,
Wisconsin, High winds associated with thunderstorms damaged barns and power lines
near Wausau and 3.44 inches of rain fell at Watertown, in about 2 hours on Tuesday
morning. Locally heavy rains also fell in the normally dry areas of eastern
Arizona - 1 to 2 inches in some localities - on Tuesday. On Wednesday, generous
rains fell in southern Utah. Heavy showers - nearly 3 inches - fell at Bemidji,
Minnesota, Thursday night and Friday morning when a Similar amount fell in
northern New Jersey. Only light, widely scattered showers fell in the Southeast.
In some eastern areas, last week was the driest week since mid-June, Much of the
Desert Southwest and parts of the Corn and Cotton Belts received no rain,

TEMPERATURE: Comfortably cool temperatures occurred from the Pacific Ocean to
the western Great Plains and in the northern border States while unseasonably hot
weather persisted from the central and southern Great Plains to the Atlantic coast.
Throughout most of the week, a front stretched from the Southwest to the northern
Great Plains, thence eastward to New England. Cool air lay west and north of the
front. A HIGH, centered over the Southeast drove hot, humid, gulf air northward
over mid-America, Daytime temperatures over the West were mostly in the cool,
comfortable 70's except in the southwestern deserts where they reached the 90's
on most days. Nighttime temperatures dropped to the 40's and 50's except, at
higher elevations, where minimums below 40° occurred, Flagstaff, Arizona, eleva-
tion 7,000 feet, registered 24° Friday morning, August 23, the coldest August
temperature of record at Flagstaff.’ The previous record-low for August was 33°,
Numerous locations in Utah registered temperatures near or below the freezing
mark on Friday morning. Temperatures along the Canadian border ranged from the

upper 50's and 60's in the early mornings to the 70's on most afternoons, Un-
Weather continued on page 850.

Weather continued from page 830.

seasonably hot weather persisted from the central and southern Great Plains to the
Atlantic Ocean. Pickstown, South Dakota, registered 100° or higher on several
afternoons and maximums at Columbia, South Carolina, averaged 101°. Last week was
the hottest week of the year in South Carolina, the hottest since mid-June 1966 in
Kentucky, the hottest since 1955 in Pennsylvania, and since 1954 in North Carolina.
Dew point temperatures exceeded 70° over much of the Central and East. ‘The per-
sistence of the combination of high temperature and high humidity made the weather
especially uncomfortable to the people whose work kept them out of doors. The
front moved across the East over the weekend and temperature and humidity dropped
to comfortable levels. (Summary supplied by Enviornmental Data Service, ESSA.).

WEATHER BUREAU'S 30-DAY OUTLOOK
SEPTEMBER 1968

The Weather Bureau's 30-day outlook is for temperatures to average above normal
over the South and portions of the Ohio Valley. Below normal values are expected
from the northern and central Plains to the Southwest, and also in the Northeast.
Near normal temperatures are in prospect elsewhere. Precipitation is expected

to exceed normal over a wide area from the Pacific Northwest through the Rockies
and Plains to the Great Lakes region. Subnormal totals are expected: in the
Southeast and the Far Southwest, while near normal amounts are in prospect in
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.

WEATHER OF THE WEEK ENDING SEPTEMBER 2

HIGHLIGHTS: The first nippy weather of the fall covered the East last week. All-
time high August temperatures occurred along California's coast. Precipitation
ranged widely. Heavy showers fell in the Oklahoma and Texas Panhandles and a
tropical depression flooded northeastern Florida.

PRECIPITATION: Steady light rain in the Pacific Northwest was interrupted
briefly about midweek, but more light rain fell there over the weekend, Heavy
showers fell Tuesday in southeastern Nebraska, western Iowa, and northern Kansas
with some 6-hour totals ranging from over an inch to about 4 inches. Rains
continued in Nebraska and Kansas on Wednesday and Thursday spreading southward
to northern Texas and northward to the Dakotas. Spots in the Texas and Oklahoma
Panhandles received 6 to 8-inch totais in heavy showers Thursday. Streams
overflooded and water flooded highways, homes, and business establishments. A
tropical depression over northern Florida dumped over 15 inches of rain at Jack-
sonville, Florida, in 96 hours. Considerable flooding occurred in northeastern
Florida. Brunswick, Georgia, received over 8 inches in 5 days. In sharp con-
trast, a large area from Louisiana to eastern Kentucky received no rain or only
light sprinkles. Another dry area included southern New England, New Jersey,
Pennsylvania, and southward to central North Carolina. In the West, the dry
area extended from southern Idaho to southern and central California.

TEMPERATURE: Temperatures averaged below normal from the Great Basin to the
Atlantic coast. Much of the area from the Texas Panhandle to New York and from
Wisconsin to northern Alabama averaged 7-10° below normal. Some parts of this
large area experienced the coolest weather since late May. In contrast,
California and the western parts of nearby States averaged warmer than normal.
Several coastal stations in California registered alltime high August tempera-
ture readings. Clear skies and pleasantly cool weather prevailed over most of
the parts of the United States at the beginning of the week. Only the Deep
South experienced very warm temperatures, such as 97° at Augusta and Macon,
Georgia, and Mobile, Alabama, on Monday. Early morning temperatures averaged
mostly below normal. Thursday morning much of the area north of the Ohio River
registered minimums in the 40's and the temperature at Nashville, Tennessee,
dropped to 52°. The highest temperature at Atlanta, Georgia, on Saturday was
65° compared to 98° on the previous Saturday. Temperatures were more changeable
in mid-America. To illustrate, Grand Island,Nebraska, registered the following
daily maximums: Monday 94°, Thursday 62°, and Sunday 82°. Subfreezing tempera-
tures occurred in the Colorado Rockies and light frost was noted in the mountains
of West Virginia. (Summary supplied by Environmental Data Service, ESSA.)

WEATHER OF THE WEEK ENDING SEPTEMBER 9

HIGHLIGHTS: Cool autumn weather prevailed over most of the Nation. Very little
rain fell west of the Rockies. Precipitation totals east of the Rockies ranged
widely, but most veas received one to two inches,

PRECIPITATION: Light rain fell in the northern Rockies, northern Great Plains,
and the Northeast early in the week. Much heavier and more widespread showers
occurred at midweek, however, in the humid gulf air in advance of a front that
stretched from the Great Lakes to the southern Great Plains. Amounts ranged wide-
ly from light sprinkles to several inches. Especially heavy rains fell in-eastern
Texas and in LouiSiana where on Thursday morning Several stations registered 24-
hour totals exceeding 4 inches. Shermans Dale, Pennsylvania, registered 4.85
inches on Friday morning. Most of the area from the Great Lakes to the Gulf of
Mexico and eastward to the Atlantic coast received light to moderate rain from
Thursday afternoon to Friday forenoon, The weekend brought sunny and cool weather
to the East but turbulent, thundery weather to the northern Great Plains. Thunder-
storms occurred from Montana to Wisconsin and southward to Kansas. Most of the
thunderstorms produced only light showers, but many were accompanied by gusty
winds and hail. Very little rain fell west of the Rockies and wide areas from
Washington to southern California and western Arizona received no rain.

TEMPERATURE: Temperatures last week averaged above normal in the Pacific States,
below normal from the Great Basin to the Appalachians,and near normal near the
Great Lakes and along the Atlantic coast. Warm and moist air covered the central
Great Plains and most of the South early in the week. Afternoon temperatures
reached the 80's in central and eastern South Dakota, and the 90's from south-
western Nebraska to central Oklahoma. Cool air pushed in from the North and by
midweek the warm air had retreated to southern Kansas and Missouri and afternoon
temperatures in the 50's and 60's were common over the northern Great Plains.
Minimums dropped to below freezing in western Wyoming and in the Colorado Rockies
on several mornings in the latter half of the week. Texas warmed quickly over the
weekend with maximums mostly in the 90's by Sunday, but cool temperatures contin-
ued over the northern Great Plains. No marked temperature trends occurred in the
Far West and in the East. (Summary supplied by Environmental Data Service, ESSA.)

WEATHER BUREAU'S 30-DAY OUTLOOK
MID-SEPTEMBER TO MID-OCTOBER 1968

The Weather Bureau's 30-day outlook calls for temperatures to average below
seasonal normals over most of the area lying between the Appalachians and the
Rockies except for near to above normal along the northern border States. Above
normal temperatures are expected in the Pacific Coast States. Except for below
normal temperatures over eastern New England near normal averages are expected
to prevail elsewhere, Precipitation is predicted to exceed normal over most of
the central portion of the Nation lying between the Rockies and the Appalachians
and also along immediate coastal regions from Hatteras to southern New England.
Subnormal amounts are indicated over the Far Southwest and part of the extreme
Southeast. In other areas near 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.

. eav pr ecipl ta tio ah most area of
half mA eA Oo n n SS)

PRECIPITATION: During the first three days of the week a frontal system moving
eastward from the Mississippi Valley, produced moderate to heavy rainfall rather
generally from lower Mississippi Valley and upper Ohio Valley to the Atlantic
coast. Unusually heavy amounts were reported from northern Virginia into
southeastern Pennsylvania with up to six inches measured in the Baltimore
Maryland, and Washington, D.C., areas. Little or no rain fell in eastern Alabama
however, and only very light amounts in the Florida Panhandle where moderate :
drought continues. A weakening tropical storm from the Pacific brought rain

into the western gulf region during the weekend. A cold front in northwestern
Washington early in the week reached the Great Plains by the end of the period
Rainfall along the front was mostly light and scattered, Weekly totals in the
western Great Lakes and upper Mississippi Valley, the central and upper Great
Plains, and Far West ranged mostly from none to a few hundredths, with amounts
over an inch limited mainly to eastern portions of South Dakota and Nebraska

and the north Pacific coast. Weather continued on page 909,

CITRUS

FALSE SPIDER MITES (Brevipalpus spp.) - FLORIDA - "An 18-year survey of Brevipalpus
mites on citrus was analyzed to account for the almost complete disappearance in
Florida of leprosis (nailhead rust, Florida scaly bark). B. californicus (Banks),
the mite responsible for leprosis in Florida, was found occasionally on citrus in
various parts of the State, but only in Volusia County and in Sumter County was

it accompanied by leprosis. B. obovatus Donnadieu, the cause of leprosis in
South America, was encountered twice on citrus (a new host record for the State),
but symptoms of leprosis were not in evidence. In caged experiments, however,

B. obovatus did produce leprosis. B. phoenicis (Geijskes) was found on citrus
throughout the State, often in large numbers, but no economic consequences
attended infestations. A description is given of 'false leprosis,' a disorder of
unknown etiology that is often mistaken for leprosis." (Knorr, Denmark, Burnett).
This is the abstract for the paper "Occurence of Brevipalpus Mites, Leprosis, and
False Leprosis in Florida."* (PPC).

10-acre spot inside initially treated area; controls applied to this spot
September 7. Re-treatment of general area begun second week of September. No
spread observed beyond boundaries of initially treated area. (Olson).

Weather continued from page 894.

TEMPERATURE: Cold, dry air, moving in behind the frontal system that crossed the
eastern portion of the Country the first three days of the period, reduced
minimum temperatures to record low levels (40's and 50's) for the 10th and lith
in portions of the lower Mississippi Valley. Fair, sunny weather with warm days
and cool nights was the rule the rest of the week. The western half of the
Nation was abnormally warm with maxima in the 90's in the northern Great Plains
and exceeding 110° in the southwestern desert. During the weekend cooler air
covered the Western States and frost was reported in the higher mountains as far
south as Arizona.

VIOLENT WEATHER: Frontal thunderstorms caused damage in scattered areas of the
East early in the period. Tornadoes were reported at Cedar Springs, Michigan,
and ten miles north of Toledo, Ohio, on the 9th, and seven miles southwest of
Lake Charles, Louisiana, and 10 miles north of Winner, South Dakota, on the

14, with damage limited to some farm buildings. High winds downed a 220-foot
radio tower at Beaumont, Texas, on the 15th. (Summary supplied by Environmental

WEATHER OF THE WEEK ENDING SEPTEMBER 23

HIGHLIGHTS: Early season cold in Northwest with heavy snowfall in northern
Rockies. Frequent thunderstorms with scattered unusually heavy downpours in
mideontinent. Mostly fair, sunny weather in East.

PRECIPITATION: With a slow eastward moving cold front in the midcontinent area
irst part of the period, moderate to heavy rains and thunderstorms were
widespread from the Mississippi Valley to the Appalachians on the 16th and 17th,

continuing in the upper Mississippi Valley and Great Lakes area and along the
western slopes of the Appalachians on the 18th and 19th. Warren, Arkansas,
measured over 5 inches in a 24-hour period ending on the morning of the 16th, and
more than 4 inches in 12 hours were reported in eastern Kansas and Nebraska.

On the 17th tornadoes caused some damage to Beeville, Texas, and Wiehaven
Tennessee, and another tornado was reported near Cherokee, Iowa. High winds
damaged homes and downed trees at Batesville, Arkansas, on the same date. A
slow moving cold front entered the Pacific Northwest on the 17th and reached

the Great Plains by the end of the week. Snow fell in the higher Rockies

behind the midcontinent cold front and Leadville, Colorado, reported 3 inches

on the ground on the morning of the 17th. On the 18th snowfall was reported
down to 4,000 to 5,000 feet in Idaho and Montana. By the 20th a heavy snowstorm
had developed in the northern Rockies and trees and utility lines were downed by
wind and a foot of snow at Anaconda, Montana. On the morning of the 21st Cut
Bank, Montana, reported 3 inches of snow on the ground and Helena 2 inches.

On the last day of the period tornadoes were reported near Orange City, Hospers,
and Alton, Iowa. Weekly precipitation totaled over 2 inches in much of the
Mississippi Valley, along the north Pacific coast, and scattered spots in the
northern Rockies. Little or none was reported east of the Appalachians from
North Carolina to northern Maine and in the Far Southwest.

TEMPERATURE: The last week of the astronomical summer was much colder than
normal in the West, about normal in the midcontinent area and South, and warmer
than normal from the upper Mississippi Valley eastward. Generally rising
temperatures in the Northeast during the week reached the middle and high 80's
during the weekend. Temperatures were below normal most of the week in the
West. Cold air moving in behind the midwestern cold front reduced temperatures
to unusually low levels in the lower Great Plains about midweek, On the morning
of the 18th El Paso, Texas, recorded an early season low of 45° and Fort Worth
one of 51°. (Summary supplied by Environmental Data Service, ESSA.)

THE GREENBUG IN THE ATLANTIC COAST STATES

(Schizaphis graminum (Rondani))
Homoptera: Aphididae)

1/

Mortimer D, Leonard

The greenbug, for many years placed in Toxoptera, apparently was first recorded
in the United States at Culpeper, Virginia, in 1882. Within the next two or
three decades it became distributed throughout the country except in New York,
New Jersey, Delaware, Connecticut, Rhode Island, New Hampshire, and Maine, Al-
though early and injurious outbreaks were periodically recorded in Georgia, South
Carolina, North Carolina and Virginia, the greatest injury occurred in the grain-
producing States in the more central part of the country. This is still true.
Wheat and oats are the principal grain crops affected. The greenbug is one of
the first aphids recorded to produce widespread and injurious outbreaks in the
United States.

Because a great deal more is known about the greenbug in the large grain-producing
States, it seemed desirable to collect the available records for the Atlantic
Coast States. Many of the records included here were published in the Insect Pest
Survey Bulletin of the former U.S. Bureau of Entomology. Numerous others previ-
ously were unpublished.

The States are arranged geographically from Florida to Maine. Under each, the
data on the greenbug are arranged in chronological order. Although the District
of Columbia and Pennsylvania do not quite reach the Atlantic Ocean, the available
records for these are included. Since the greenbug has been found in New Bruns-
wick and Nova Scotia in eastern,Canada these also are included.

Appreciative acknowledgement is made to Survey and Detection Operations, Plant
Pest Control Division, Agricultural Research Service, United States Department of
Agriculture for making available records from their Scientific Records System.
These are indicated by "IPS" in reference to their original inclusion in the
former Insect Pest Survey files and "SRS" for the present system. Thanks are also
due to individuals in the several States who have supplied records, many of which
were unpublished.

FLORIDA

The following records are from slides in the Florida Agricultural Experiment Sta-
tion. They were kindly furnished to me by Dr. A. N. Tissot of the University of
Florida (Emeritus) and determinations were made by him unless otherwise stated.
Names in parentheses are those of the collectors,

Two Slides presumably made by A. L. Quaintance from Lake City, May 10, 1897.

H. Beyer); March 9, 1928, on oats (Tissot). Lake Alfred--July 10, 1929, on crab-
grass (W. L. Thompson). Gainesville--February 2, on wheat (W. B. Tisdale) and
March 1, 1932, on wheat (Tissot); January 25, 1932, on oats (Camp and Tissot) ;

decumbens. Belle Glade--November 2, 1953, on fescue (Genung). Kendall--December
17, 1953, on Pangola grass (D. O. Wolfenbarger). Gainesville--January 14, 1953,
on oats in greenhouse (Kuitert), on oats in air-conditioned chamber May 3, 1957,
(H. H. Luke), and March 11, 1957, on Pangola grass (Tissot and Kuitert).

The following are from Plant Pest Control Division records: Quincy area--
November 1946, considerable damage to oats (F. S. Chamberlin, IPS). Belle Glade--
December 12, 1952, severe infestation of oats for grazing (W. C. Genung, SRS).
Population on oats and Pangola grass attacked excessively by hymenopterous. para-
sites during January 1953 in the Everglades; aphids appearing again in the Ever-
glades on Pangola grass October 29 and heavy parasitism in November. (Genung et
al., Summary 1953 in SRS). "Nymphs and adults have caused some apparent damage
to Pangola grass .. . at the Smith Cattle Ranch, Davie, December 23. Caused a
medium infestation of nymphs and adults on Pangola grass at the Imperial Ranch,
Davie; and 2 to 3 nymphs and adults per plant on Pangola grass 2 miles east of

Davie. No apparent damage was indicated. December 31." (H. A. Denmark, summary
1954 in SRS). "On Pangola grass pastures . . . showed an increase during the
first 3 weeks of March at Everglades Experiment Station." (Genung, summary 1955
in SRS).

For 11 of the 15 years between 1949 to 1963, Dr. Tissot collected winged aphids
which had been "trapped" by the sticky leaves of tobacco. This was done in
Gainesville during the tobacco-growing season from April to June. The number of
specimens of the greenbug by years is shown in the following table:

GEORGIA

"Found in the following counties: Tift, Charlton, Brooks, Wilcox, Richmond and
Johnson on oats and wheat."' (Report by M. S. Yeomans to IPS, March 7, 1929).

"Fort Valley--November 16, 1929, on oats. The infestation is unusually heavy
this year and considerable damage has already-been done. Deadened areas are
appearing in green fields as a result of the damage by this insect." (Report by
O. I. Snapp to IPS).

"During the late winter and spring an investigation was made of the unusual out-
break of the green bug or spring grain aphid, which affected oats and wheat in the
Piedmont and upper Coastal Plain regions of Georgia, as well as neighboring
states, Almost every farmer interviewed was entirely unfamiliar with green bug
injury and this outbreak was evidently the worst ever suffered in Georgia. The
insect is not new to the state, as there are records of outbreaks in several
years, notably 1907 and 1914, and there was damage at Experiment in 1935.

"Injury by this insect appeared first as dead spots and streaks in the grain
fields, but finally large areas or whole fields were destroyed in some cases,

In some fields spots were not so evident, but plants over a wide area were
thinned out. According to the records obtained, injury was first observed by
grain farmers late in December of 1936 and became widespread during the following
month. Injury seemed to slack during February, but continued again during March.
Green bug feeding had ceased entirely by May 20 when harvest was beginning.
Almost all the damage was to oats, although an occasional field of wheat was
attacked,

- 932 -

"The survey brought out the following points as to green bug attacks on oats:

1. Oats sown before October 15, in the Piedmont region, uSually had more
injury than oats sown the latter part of October or early November.

2. Grain on poor land, such as in washed areas, suffered more than that on
fertile land. Injury was more evident on gray, Sandy land than on the heavier
red soils.

3. The outbreak was caused by the unuSually warm weather during the fall
and winter, such weather making development of the green bug rapid. There was a
small excess in temperature for the state during September and October, a small
deficiency in November, and an excess again December, January and February. The
warmest period began December 22 and ended January 31. This was the warmest
January on record for Georgia, according to reports of the U. S. Weather Bureau,
the average daily excess for the state being 11 degrees.

There was an excess in rainfall in the same months in which the temperature was
high but the possible influence on insect numbers is not known.

4, Infestation of a field often started from volunteer oats.

5. Throughout the counties surveyed, no difference in injury between oat
varieties was apparent though in the Agronomy plots at the Experiment Station
some interesting differences of this type did show." (Georgia Agricultural Exper-
iment Station Annual Report 1936-1937, pp. 48-50). No details are available to
substantiate the outbreaks in 1907 and 1914. T. L. Bissell tells me he prepared
the foregoing report on the greenbug.

Reynolds--1941, "Two reports from Reynolds (west central Georgia) of greenbug
injury to oats dated January 9 and 15. Considerable patches of oats have died."
(Report by T. L. Bissell to IPS).

On January 29, 1941, R. W. Harned reported as follows to IPS: "In a letter dated
January 27, 1941, Dr. P. M. Gilmer, Tifton, Georgia, states that the green bug is
seriously attacking winter oats throughout the State of Georgia. He has noted
that the infestation is rather heavy in the vicinity of Tifton and in several
other counties of Southern Georgia. He states that Mr. Parham and Mr. Turner of
the Georgia Coastal Plain Experiment Station recently made a rather extended trip
through the State and reported that the damage is exceptionally heavy.

Dr. Gilmer states further that based on his observations of this insect in Kansas
and Oklahoma he considers the infestation in Georgia rather heavy and that ex-
tensive damage will undoubtedly be caused. He has observed some fields in which
all of the plants have been killed over areas as large as half an acre, In his
opinion, although the damage will be serious, it will not be as great as seems to
be anticipated by many of the farmers."

"There is still a small infestation of green bug, occurring sporadically on oats
in Tift, Lowndes and Echols counties. There has been a build-up of parasites,
such as Lysiphlebus, upon this grain aphid." (Report by P. W. Gilmer to IPS,
May 3, 1941).

"There has been a mild outbreak of the greenbug on oats this winter. Reports
come from Taylor County, January 9 and 15 (2 farms); Spalding County, January 31;
and Pike County, February 7--Spots in fields had died out; on one farm the esti-
mated loss was 10 percent. The parasite, Lysiphlebus testaceipes, has been at
work from the first report, January 9." (Report by T. L. BisselI to IPS, Feb-
ruary 20, 1941).

"Damage to grain by greenbugs has increased during the last two weeks, and some
farmers have used airplanes to apply insecticides for control."" (Report by O. I.
Snapp, Fort Valley, to SRS, February 2, 1950).

- 933 -

"Infestations were light to moderate and well distributed over the State on small
grain." (Report by W. C. Johnson, summary 1957 in SRS).

SOUTH CAROLINA

Regarding the outbreak of 1903, Webster and Phillips (p. 24) say: "This outbreak
was, however, an incipient one and resulted in little injury, the seriously
infested areas being confined to northern Texas, exclusive of the ‘Panhandle, '
with possibly the country in the then Oklahoma and Indian Territories bordering
the Red River, and in South Carolina."

"North and South Carolina also suffered somewhat from the depredations of this
insect in 1907. The senior author made a trip into this section reaching Sumter,
S. C., April 17, 1907. He found that all fields of oats, the only grain sown,
were more or less affected; here and there brown areas occurred, showing the
characteristic work of Toxoptera. This condition was noticeable from Sumter,

S. C., to Charlotte, N. C., indicating that the infestation was general."
(Webster and Phillips, p. 36).

Recorded from Bennettsville, Hartsville, and Monetta 1903 and Batesburg 1911.
(U.S. Bur. Ent. correspondence).

Columbia--April 13, 1925, on winter oats. "Infestation general but slight.
Ladybird beetles and syrphids at work. No serious damage expected. Oats heading
out.’ (Report by P. Luginbill to IPS).

Oconee County--January 10, 1927, specimens received and reported as destroying a
two-acre field of oats. It possibly occurs in small numbers elsewhere in the
State but has not been observed or reported. (Report by J. O. Pepper to IPS,
February 21, 1927).

Florence--April 20, 1935, several outbreaks on oats; natural enemies active
(report of F. Sherman and associates to IPS); spring 1935, severe outbreaks on
oats and rye (coll. by C. F. Rainwater and det. by P. W. Mason); and November 16,
1948, on oats (coll. by L. C. Fife and det. by L. M. Russell). [From files,
Department of Entomology, Clemson University. ]

Barnwell County--1937, specimens collected on oats and rye. (Report by W. C.
Nettles to IPS).

Considerable infestation and damage to early planted winter oats and wheat in
eastern half of State, March 22, 1941. (Report by Nettles to IPS).

Brunson--1929, injuring oats. (Report by J. N. Tenhet in Insect Pest Survey Bul.
9(1):9, 1929).

Clemson College--April 19, 1931, on oats (coll. by Nettles and det. by A. N.
Tissot); April 24, 1960, 2 alatae in trap light (det. by B. F. Coon). [In files,
Department of Entomology, Clemson University.]

NORTH CAROLINA

Mebane, Alamance County--January 26, 1890, reported as ruining both wheat and
oats. (Webster and Phillips, p. 20).

Occurred on wheat and oats in March 1907 in Franklin and Forsyth Counties and in
April in Davie, Forsyth, Guilford, Union and Rowan Counties. (Report by F. Sherman
to IPS).

- 934 -

"We received a letter with specimens from Mr. L. M. Smith, Mr. Sherman's assist-
ant, at Newport, Carteret County, N. C., stating that he found a small field of
oats in the outskirts of town that was considerably damaged by Toxoptera. This
county is on the coast and Newport has an elevation of 19 feet. From this it
seems that in all probability Toxoptera covered the entire State."' (Webster and
Phillips, p. 37). This note is in connection with the 1907 outbreak.

Chadbourn--November 19, 1929, ''There is a rather wide-spread infestation of this
aphid on early planted oats in this section. Some of the growers are complaining
of losing their stand of plants due to this insect. The tips of the leaves are
already dead on many plants and all living areas of leaves are clustered with
aphids."'’ (Report of W. A. Thomas to IPS).

Statesville--April 20, 1954, barley in the vicinity generally infested, in some
fields as much as 10 percent of plants with developing colonies. Infestation
south and east of Statesville less severe, Oats and wheat just becoming infested,
with single adult aphids scattered through fields. (Report by T. B. Mitchell to
SRS). :

"Was widespread in Forsyth County on small grain in the spring and in Harnett
County in the fall." (M. H. Farrier, summary 1955 in SRS).

"Negative during the 1959-60 winter. Infestation had killed 25 to 75% of some
fields of oats and rye in Nash County by early December and portions of other
fields were beginning to turn brown." (M. H. Farrier, summary 1960 in SRS).

In April 1968, Dr. Clyde F. Smith of the University of North Carolina sent me
the records of the following collections made by him: Willard--November 29,
1943, on oats; Raleigh--February 12, 1947, on oats; Lexington and Waynesville--
1958, on oats; Nashville--December 3, 1960, on oats and rye. Dr. Smith wrote,
"As far as North Carolina is concerned I am sure that the greenbug is a pest
throughout the State. This is especially true if warm weather continues late
into the fall. Most of the damage occurs in the fall rather than in the spring
of the year."

VIRGINIA

"The first examples of Toxoptera graminum to be found in America and identified
as such were probably collected with the oats plants which they were destroying
by Mr. H. S. Alexander, of Culpeper, Va., on June 15, 1882."' The authors further
state that Mr. B. F. White of Mebane, North Carolina, in a letter dated January
28, 1890, wrote that this same insect had appeared in his area in 1882, in May.
They therefore concluded . . . it seems quite likely that, while the discovery
was first made at Culpeper, Va., the insect occurred over a considerable area of
country in Virginia, extending southward into northern North Carolina Bit
(Webster and Phillips, pp. 13 and 14).

In 1907 "The senior author also found Toxoptera in destructive abundance at
Midlothian, Chesterfield County, Va., in a small meadow of orchard grass.

Mr. J. L. Phillips, the State entomologist, reported a slight outbreak at Clover-
dale, Botetourt County, Va., in rye, and stated that considerable damage had been
done in some parts of the field." (Webster and Phillips, p. 37).

"Grain aphis - Several reports lately of damage being done in Goochland County -
specimens received. Have examined fields of wheat in Shenandoah Valley Counties.
Fairly abundant in early planted fields, but apparently doing no damage ...
Fields between Richmond and Scottsville along James River all more or less in-
fested but apparently no damage."' (Report by C. R. Willey to IPS, February 23,
1932).

"We have had a number of complaints about the greenbug (Toxoptera graminum Rond.)
on wheat. These have come from a number of counties in each wheat growing section
and from Halifax County just out of the wheat belt. The County Agents have

- 935 -

reported that many wheat fields have been severely damaged by the feeding of this
pest." (Report by W. J. Schoene to IPS, February 22, 1932).

Augusta County--December 12, 1941, plants in one field of barley killed over an
area of 50 feet long and 20 feet wide but the infestation extended only 2 or 3
feet beyond this killed area. (Report by A. M. Woodside to IPS).

New Kent or Charles City County--December 12, 1956, believed causing discoloration
of oats. (Report by J. O. Rowell and det. by W. G. Evans, Office of State
Entomologist) .

Middlesex County, Nottoway County, Eastern Shore--December 5, 1958, attacking
early barley and oats severely in the lower end of Middlesex County (report by
Edwards); heavy on oats and barley on a Nottoway County farm (report by Rowell)
and were heavy on small grains on the Eastern Shore during the last week of
November (report by R. N. Hofmaster). [All records in the Office of State
Entomologist .]

Mathews County--November 29, 1966--several barley and oat fields badly infested;
farmers are considering spraying for control this week (Office of State Entomolo-
gist--report by Dinwiddie).

"Five adults collected in oatfield in Nansemond County April 30, 1968. Det. by
L. M. Russell. This is first report of species in county." (W. A. Allen,
U.S. Dept. Agr. Coop. Econ. Ins. Rpt.’ 18(26) :573, 1968).

MARYLAND

"On June 7, 1884, Mr. Albert Koebele found this species infesting wheat plants
at Cabin John Bridge, situated in Maryland a few miles above Washington . .."
(Webster and Phillips, p. 15).

"Damaged young orchard grass seedlings at Clarksville, Howard County." (U.S.
Dept. Agr. Coop. Econ. Ins. Rpt. 8(47):953, 1958).

Killed two-thirds of an oat field in Worcester County, November 13, 1959. (U.S.
Dept. Agr. Coop. Econ. Ins. Rpt. 9(48):1017, 1959).

Beltsville--October 13, 1961, alatae in yellow water pans among gladioli. (Coll.
by H. E. Wave and det. by L. M. Russell).

DELAWARE

There are no records of the occurrence of: the greenbug.

DISTRICT OF COLUMBIA

"There was an outbreak of Toxoptera in the bluegrass lawns north of the buildings
of the Department of Agriculture at Washington, D.C., in July, 1907. The infested
area .. . waS apparently confined to the space of about an acre, where it was
excessively abundant; outside of this area practically no Toxoptera could be
found.” In 1910 it was again injuriously abundant in this same area and was quite
numerous on bluegrass about the Washington Monument some 4 blocks away. (Webster
and Phillips, pp. 37-38).

Washington, D.C.--July 18, 1906, on Poa pratensis (T. Pergande -- one slide in
USNM); April 4, 1908, no food plant given, dead when found (C. N. Ainslee -- one
slide of female with one egg and young in USNM); January 1932, food plant not
given (coll. by F. M. Wadley -- one slide in Cornell Univ. Collect.). June 1,
1962, on crabgrass, Digitaria sanguinalis, a few alatae, apterae, and nymphs

- 936 -

(coll. and det. by M. D. Leonard). Two alatae in a yellow water pan on the roof
of an apartment house (10 stories high), 2 alatae during June 1962 (Leonard,
1964b) and 1 alata in the pan in July 1963 (Leonard, 1965).

PENNSYLVANIA

York--September 13, 1909, no plant given, 1 aptera, 5 nymphs on a slide in USNM.
(Coll. by V. L. Wildermuth).

"A field of timothy near Carlisle, Pa., was found by J. S. Pinckney on May 9 to
be heavily infested with Toxoptera graminum," reports Chas. C. Hill. "At this
time Mr. Pinckney observed that the field was already showing all the character-
istic 'spots' of this type of infestation, scattered throughout the field and
varying in size from a few feet in diameter to 20 yards. The field has now been
entirely ruined from this cause and will be plowed up. It is unusual to find
serious infestation from this species of aphid in this section of the country,
and F, M. Wadley believes that it has never before been reported as working on
timothy in injurious abundance. These aphids were plentiful in near-by oat and
timothy fields but were not doing any outstanding injury to them. The deter-
mination of the species was verified by F. M. Wadley.'"' (Mo. Letter, U.S. Bur.
Ent., No. 218 for May, dated June 1932).

Springbrook (near Moussic between Scranton and Pittston)--1 alata, June 13, 1945,
(Coll. by R. I. Sailer -- 1 slide in USNM).

Centre Hall--in black light traps and in yellow trays alatae as follows: May 11
and 27, June 2, 22 and 29, 1958; July 2 and 6, August 24 and 31, 1960. One to

3 alatae collected on each of the above dates. (Report from J. O. Pepper).

Dr. B. F. Coon (1968), Pennsylvania State University, operated two black light
traps from May 1 through November 26, 1960. In these a total of 213 alate
greenbugs were taken nearly all of which (194) were in June. The other dates of
collections were May - 3 alatae; July - 5 alatae; August - 1 alata; and October -
1 alata.

NEW JERSEY
No locality given (1961)--October 6 - 1 alata; October 9 - 1 alata; and November
6 - 2 alatae collected by sweeping, no host plant given. (Coll. by R. S. Filmer
and det. by J. O. Pepper).
Cranbury--June 2, 1960, on timothy grass. (Coll. by H. E. Wave and det. by C. F.
Smith). See Leonard 1964a.

NEW YORK

Sodus--August 16, 1923, infesting buckwheat. (Report by C. R. Crosby to IPS).
Ithaca--October 1-3, 1939, 3 alatae in trap. (Coll. by W. F. Rochow and det.
J. O. Pepper). North Lansing--June 15 to August 7, 1964, 2 alatae; June 9 to

J. O. Pepper). See Leonard 1968.

CONNECTICUT

Short Beach--May 20, 1953, alatae on the wing. This is the first record of the
greenbug for Connecticut. (Report by J. B. Kring to SRS).

- 937 -

RHODE ISLAND

I can find no record of the occurrence of the greenbug in this State.

MASSACHUSETTS

", , . near Boston, where it seems to have been found by Mr. Paul Hayhurst in
September, 1908 . . ." (Webster and Phillips, p. 19). I have been unable to fur-
ther substantiate this collection (M.D.L.).

NEW HAMPSHIRE

Dr. J. C. Conklin, Chairman, Department of Entomology, University of New Hamp-
shire, wrote me in April 1968 that his files contain no record of the greenbug in
New Hampshire.

MAINE

Presque Isle--6 collections of alatae in traps during August 1941 (coll. and det.
by W. A. Shands and G. W. Simpson); alatae taken in traps from June 1953-June
1963 (coll. by Shands, Simpson and H. E. Wave).

No specific locality--was present in small numbers on oats. (Report by L. W.
Boulanger and R, W. Paulson, summary 1955 in SRS).

On April 10, 1968, W. A. Shands wrote me as follows: "Over the years we recorded
Schizaphis (Toxoptera) graminum occasionally on oats but usually in trace numbers
only. Once in awhile it was fairly common on perennial grasses (mostly witch-
grass) growing in the stands of oats, however here again it was never really
abundant. From its sporadic occurrence, one might think the initial infestations
were windborne--coming from outside the Aroostook area." ;

NEW BRUNSWICK, CANADA

"The only records I have were collections taken in traps at Woodstock August 5,
1949, Point Escuminac August 29, 1951 and Alma August 6, 1951." (M. E.
MacGillivray, 1955). Fredericton--1958, on Agropyron repens (det. by Mac-
Gillivray).

NOVA SCOTIA

"I cannot give you definite records of S. graminum from Nova Scotia but I recall
that they occurred in trap catches that I examined between 1945 and 1950." (Mac-
Gillivray in litt.).

* KK KK KK KK KK OK K OK OK

It is believed the following information is of pertinent interest here:

Dr. G. B. Orlob (1961) has described from New Brunswick, Canada, Schizaphis gra-
minum phlei new subspecies. The technical description and accompanying notes are
on pages 498-500. His initial statement is as follows:

"During May, a Schizaphis-like aphid appeared on Phleum pratense L. in the
Fredericton area. Feeding habit, damage inflicted on the host, as well as
morphological characters suggested that this aphid was nothing but the well-
known greenbug, Schizaphis graminum (Rondani). . Other features, such as a yellow

- 938 -

color and the presence of exclusively apterous forms early in the season, were
not considered typical for S. graminum s. str. Soon it became apparent that the
aphid from timothy differed also from the greenbug in its host range and the pro-
duction of sexuales., Because of these characters the aphid is described as a new
subspecies of S. graminum."

The type material (an apterous viviparous female) is dated June 1, 1960, Fred-
ericton, New Brunswick, on Phleum pratense,

On page 500 under "Comments" are most interesting notes on several Schizaphis
graminum-like aphids which have been reported from the USSR and several other
European countries.

The Weather Bureau's 30-day outlook calls for temperatures to average below
seasonal normals over most of the Nation except for above normal temperatures in
the Pacific Coast States and near normal temperatures over the northern third of
the Country between the Rockies and the eastern Great Lakes. Precipitation is
expected to be subnormal over most of the Nation except for near normal amounts
in the Great Lakes region, the northwest Pacific coast, and the gulf and South
Atlantic States, with heavier amounts in Florida.

Weather forecast given here is based on the official 30-day "Resume and Outlook"
published twice a month by the Weather Bureau. You can subscribe through the

WEATHER OF THE WEEK ENDING SEPTEMBER 30

HIGHLIGHTS: Most citizens enjoyed warm sunny days and clear cool nights last week.
A cold front brought generous rains to mid-America early in the week and a
tropical disturbance drenched the Miami, Florida, area shortly after midweek.

PRECIPITATION: Heavy rains fell early in the week along a Slow-moving cold

front that Stretched from Michigan to Texas. A torrential downpour accompanied

by hail and high winds stopped traffic in the Boonville, Missouri, area late
Monday afternoon and Troy, Missouri, received 4.12 inches in a few hours Monday
evening. Heavy showers fell in north-central Texas west of Dallas Tuesday night
with some localities receiving 2 to 5 inches. Lesser amounts fell from New
England to the Carolinas on Wednesday and Thursday as the front advanced south-
eastward. Precipitation totals ranged widely in the East, however, and many

areas missed by the showers continued dry. A tropical depression doused the

lower east coast of Florida late in the week. North Miami received 9.10 inches

of rain in the 24 hours ending at noon Friday. Other spots in the area received
over 4 inches. About 0.5 inch fell at Tower Falls and La Grange, Wyoming, and heavy
showers occurred at Clovis and Los Alamos, New Mexico, but totals were generally
less than 0.25 inch from the northern Great Plains to the southern Rockies and wide
areas from western North Dakota to California received no rain or only widely
scattered light sprinkles. Weather of the Week continued on page 952.

EUROPEAN POTATO FLEA BEETLE (Psylliodes affinis (Paykull))

|
|
|
|

‘Economic Importance - This small beetle was found in July 1968 on bitter night-
‘Shade in Albany and Greene Counties, New York. On occasion, it is an important
‘pest in the Molotov Province of the Soviet Union, but is not considered serious
elsewhere in the USSR. In France, rather heavy damage occurs sporadically.

‘Adults make round holes in the leaves and larvae attack the roots of the host
plant. Although the European potato flea beetle prefers potatoes, it is generally
considered a minor pest of this crop in Europe.

Host Plants - Belladonna, bitter night-
Shade, black henbane, Lycium sp., potato,
tobacco, tomato, various other solana-
ceous plants, and hops.

Distribution - Most of Europe including
the USSR and into Siberia.
United States: New York

Life History - Under conditions in
France, overwintering adults appear in
the latter half of April when they feed

- on the foliage of potato plants or other
hosts. Females deposit eggs in May and
these hatch in 6-8 days. Larvae feed on
the rootlets and make galleries in the
roots. Here they remain almost con-
stantly. Development of larvae to pupae
takes about one month. They leave the
roots and pupation takes place in the
soil a short distance from the host
plant. Adults emerge in about 3 weeks
and are abundant during July and August.
There is one generation a year.

Description - Adult - Length 2-2.8 mm.
Ovoid, overall color light tan. Head
black, pronotum and elytra tan. Suture
of elytra narrowly bordered with brown.
Legs tan except hind femur which is black
to reddish black and very large. Ventral
surface black.

Interceptions - Adults have been taken
With dahlia roots from Poland and ina

R
R. White package of rose stock from Germany.

Adult of Psylliodes affinis

on Oahu in September 1964. Adults collected since from islands of Kauai and
Hawaii. Java-plum first known host in State. (Funasaki).

Weather of the week continued from page 956.

TEMPERATURE: Temperatures averaged above normal over parts of the Great Basin,
in New England, along the gulf coast, and in Florida, and below normal else-
where. Some areas from the lower Missouri River Valley to the middle
Appalachians averaged 4° to 7° below normal. The week began sunny and mild
over most of the Nation. The Far West cooled somewhat during the week and the
Southwest warmed again over the weekend. A cold front pushed into North

Dakota and Minnesota early in the week and by the weekend had reached the Gulf
of Mexico. Mild, sunny weather preceded the frontal passage but temperatures
tumbled sharply as it passed. Temperatures in the central Great Plains dropped
40° to 50° from Wednesday afternoon to Friday morning; for example, from 81°

to 32° at Moline, Illinois, during that period. Freezing temperatures occurred
as far south as northern Arkansas Friday morning and by Saturday most of
Kentucky and West Virginia and nearby portions of neighboring States had
experienced freezing weather. Asheville, North Carolina, registered 29°
Saturday morning. Over much of the Central and East, this was the first major
cold outbreak of the season and brought the coolest weather since the end of
May. (Summary supplied by Environmental Data Service, ESSA.)

WEATHER BUREAU'S 30-DAY OUTLOOK

MID-OCTOBER TO MID-NOVEMBER 1968

The Weather Bureau's 30-day outlook calls for temperatures to average below
seasonal normals over the southern portion of the Nation lying between the
Appalachians and the southern Plateau region. Above normal averages are expected
along the Atlantic seaboard and in the Great Lakes region. In unspecified areas,
near normal temperatures are indicated although with large intramonthly fluctua-
tions. Precipitation is expected to exceed normal over most of the eastern half
of the Nation and also over the Pacific Northwest. Subnormal amounts are in-
dicated for the far southwestern and western portions of the northern Plains.
Elsewhere, near normal’ precipitation is indicated.

Weather forecast given here is based on the official 30-day "Resume and Outlook"

published twice a month by the Weather Bureau. You can subscribe through the

Superintendent of Documents, Washington, D.C. 20250. Price $5.00 a year.
WEATHER OF THE WEEK ENDING OCTOBER 14

HIGHLIGHTS: Typical autumn weather. Cold Canadian air brought freezing tempera-
tures to the intermountain region and most of the Rockies as gulf air struggles
to continue the mild weather over mid-America. A Pacific storm brought the first
general rains to California and snows to the western mountains.

PRECIPITATION: Light snow fell in the northern and central Rockies early in the
week. Much of the snow melted as it fell but by 8 a.m. Tuesday, 1 inch had
accumulated at Laramie, Wyoming. Snow fell Tuesday afternoon at Denver and
Colorado Springs, Colorado. More cool, wet weather moved into the Pacific Northwest
over the weekend. Substantial rains fell along the Washington and Oregon coast
with snow above 4,000 feet. The wet weather spread southward bringing the first
general rains of the season to California with snow above 8,000 feet. By Sunday
the storm extended across the northern Rockies and was leaving a blanket of snow
in the higher elevations. Heavy thunderstorms occurred from eastern Texas to the
middle Mississippi River Valley Tuesday afternoon and early Wednesday. A few
twisters occurred in Texas and the torrential rains caused a quick rise in the
streams in Oklahoma and Missouri. Rains in the Southeast came early in the week
with South Carolina benefiting from the first general precipitation in 2 months.
Light rain fell in the Great Lakes region and the Ohio River Valley at midweek.
New England received general rains on the 7th with additional showers on the 10th
Weather of the week continued on page 988.

FLY (Sepedon sauteri) noted on taro foliage at Keanae and Waihee, Maui; appears
established in both areas. Flies last released on Maui in July 1968. (Miyahira).

Miscellaneous Pests - Chemical baits for GIANT AFRICAN SNAIL (Achatina fulica)
Continued at Kona on Hawaii Island and at Poipu and Wahiawa on Kauai. Five live
juveniles collected during September at Kona. No live snails detected on Kauai.
Close surveillance will be maintained during rainy season. (Yoshioka, Sugawa).
First and second instars of a GRASSHOPPER (Oedaleus abruptus) numerous on short
grass in localized areas at Hickam Air Force Base, Honolulu, Oahu. First
incidence of heavy nymphal populations in treated areas. First heavy rains of

year apparently triggered egg hatch. (Olson, Otsuka).

and llth. A few snow flurries were noted in the higher mountains in northern New
England on Friday. Widely scattered light showers fell in the Florida Peninsula
on several days. Arizona and New Mexico and nearby portions of neighboring States
received no rain or only very light sprinkles.

TEMPERATURE: AS warm, moist air streamed northward over mid-America early in the
week, much colder air plunged southward through the western interior. On
Wednesday morning the temperature dropped to 9° at Evanston, Wyoming, and to 21°
at Alamosa, Colorado. Mild weather continued over the south with afternoon
readings in the 70's and 80's and early morning readings mostly in the 60's.
Quick weekend warming occurred over the central Great Plains. Pierre, South
Dakota, registered 86° and Fargo, North Dakota, 80° on Sunday afternoon. A
warming trend occurred over the East with weekend temperatures over much of the
Northeast reaching the 70's by Sunday afternoon. Cool weather persisted over the
West, however, with most of the area from the Pacific Ocean to the western Great
Plains in the north and to the Continental Divide in the south averaging below
normal. Much of the Northwest averaged 4° to 8° below normal. The middle
Mississippi River and the Ohio River Valleys also averaged slightly below normal.

WEATHER OF THE WEEK ENDING OCTOBER 21

HIGHLIGHTS: Canadian cold brought a hard freeze to much of the West and
interrupted the Indian Summer in the East. Heavy rains fell in mid-America and
Hurricane Gladys drenched the Florida Peninsula and parts of the Carolinas.

PRECIPITATION: Precipitation in the Far West early and late in the week left
several inches of rain along the Washington and Oregon coast with lesser amounts
inland in Washington and Oregon and along the California coast. Snow accumulated
to 30 inches above 5,500 feet in the Cascades. Only light rain fell along the
eastern slopes of the Sierras and little or none in the deserts. Snow flurries
fell in northern and central Rockies accumulating to 1 to 2 feet in the higher
mountains in Wyoming but to only an inch or less at most low elevations. Heavy
showers fell over parts of mid-America Tuesday and Wednesday with totals ranging
from 2 to more than 6 inches scattered from the Oklahoma Panhandle to central
Minnesota. Beresford, South Dakota, registered a weekly total of 7.50 inches.

Weather of the Week continued from page 998.

TEMPERATURE: Cold air spilled into the West. Scattered western localities
registered freezing temperatures on Monday morning and by Thursday morning a hard
freeze had occurred over most of the Great Basin and the Rocky Mountains. Alpine,
Texas, registered 32° Friday morning. The cold air spread eastward. Grand Island,
Nebraska, registered 86° Tuesday afternoon but only 61° on Wednesday. While the
Canadian blast held afternoon temperatures in Montana and Wyoming in the 40's early
in the week, southerly winds continued to pump summer heat northward over the
central and eastern parts of the Nation. Maximums reached 80° at many localities
from Lower Michigan to northern Maine. Houlton, Maine, registered 80 on
Wednesday. <A cold front moving southeastward in the latter part of the week
interrupted the Indian Summer. On Friday afternoon temperatures remained in the
60's as far south as Huntsville, Alabama. Temperatures averaged below normal

over most of the West and above normal over the East. Much of the Great Basin and
the western Slope of the Rockies averaged 4° to 7° below normal while most of the
northeast quarter of the Nation averaged 6° to 16° warmer than normal. (Summary

COOPERATIVE ECONOMIC INSECT REPORT

ESTIMATED LOSSES AND PRODUCTION COSTS ATTRIBUTED TO
INSECTS AND RELATED ARTHROPODS - 1967

Introduction

Prior to 1966 insect loss estimates were published in the Cooperative Economic
Insect Report as individual reports. An attempt has been made for the third year
to condense loss estimates from the various States into a single report. This
gives a more meaningful and better overall picture of the crop losses. The data
has been compiled from the crop loss estimates submitted from 19 States. The
entomologists responsible for the 1967 estimates and their respective States are
listed below.

J.E. May Arizona

W.P. Boyer Arkansas
G.Y. Funasaki Hawaii

C.E. White Illinois
J.H. Simpson Kansas

J.L. Hellman Maryland
R.G, Flaskerd Minnesota
R,L, Dinkins Mississippi
D.L, Keith Nebraska
R.C, Bechtel Nevada

S.R. Race New Jersey
G.L, Nielsen New Mexico
W.J. Brandvik North Dakota
J.M, Lamdin Oklahoma
P,A, Jones South Dakota
S.E. Bennett Tennessee
L.R, Green Texas

W.A, Allen Virginia
M.S. Conrad Wisconsin

Copies of the report were sent to the States involved for review prior to
publication, Some suggestions for improvement were made.

WEATHER OF THE WEEK ENDING OCTOBER 28

HIGHLIGHTS: Canadian cold continued to pour into the East bringing the coolest
weather Since March to some areas. Hard freezes occurred in the Deep South.
Snow flurries occurred from the Great Lakes to the northern Appalachians. Warm
air melted the snow below 5,000 feet in the Cascades.

PRECIPITATION: Scattered thundershowers occurred from Wisconsin to northern Texas
on Monday, October 21, in connection with a cold front which was advancing

across mid-America. Several spots in Iowa and Missouri received more than an
inch but totals generally were much less. Light showers occurred from the Far
Northwest to the Dakotas early in the week. The midweek brought rain to the
Great Lakes region and the Northeast. Also generous showers to the Texas coast
and the southern portion of the Florida Peninsula with 1.04 inches falling at
West Palm Beach in less than an hour on Wednesday. Numerous thunderstorms
occurred in the Northeast Thursday evening. Amounts ranged widely but a few spots
received more than 1 inch. Williamsport, Pennsylvania, received 1.70 inches,
Light snow flurries fell from the Great Lakes region to the northern Appalachians
on Friday accumulating to 1 inch at Sault Ste. Marie, Michigan, before melting.
Light snow fell from the Great Lakes region to the Appalachians on Friday and by
Saturday morning had whitened some mountain areas in West Virginia. Light
precipitation fell over the North Central States on Sunday - snow and rain mixed
in parts of Minnesota and Michigan; light rain as far south as Missouri. Wide
areas from California to the western Great Plains received no rain. Some light
sprinkles fell in the western Great Plains.

TEMPERATURE: Fine autumn weather with mild sunny days and clear cool nights pre-
vailed over much of the Nation early in the week with subfreezing temperatures

on most mornings over most of the Great Basin and the Rocky Mountains. Afternoon
temperatures along the South ranged from 101° on Wednesday and Thursday at
Thermal, California, to the 80's from Arizona to South Carolina. Warming
occurred over the West during the week and temperatures averaged a few degrees
above normal. In contrast, temperatures over the East dropped sharply as cold
air from Canada flowed toward the gulf. Maximum temperatures over the East

on Friday ranged from the 40's near the Great Lakes to the 60's along the gulf.
Tallahassee, Florida, registered 32° Sunday morning. Warming occurred in the
East Sunday afternoon and 60° temperatures were registered as far north as Ohio
and Pennsylvania. Some spots along the Ohio River and in the middle Mississippi
River Valley averaged 5° to 7° below normal. New England and southward along

the Atlantic coast to Cape Hatteras averaged slightly warmer than normal.

WEATHER BUREAU'S 30-DAY OUTLOOK
NOVEMBER 1968

The Weather Bureau's 30-day outlook is for temperatures to average below seasonal
normals over the southeastern third of the Nation with greatest departures in the
South Atlantic and East Gulf States. Predominantly above normal temperatures are
expected over the western half of the Country. In unspecified areas near normal
averages are indicated. Precipitation will exceed normal along the west coast,
the west and central gulf coast, and over much of the Northeast. Subnormal
rainfall is expected over the Rockies, the central Plains, and the upper
Mississippi Valley. Near normal totals are in prospect elsewhere.

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 NOVEMBER 4

HIGHLIGHTS : Cooler weather came to the West during the week while a warming trend
occurred in the East. Most of the precipitation fell after midweek.

PRECIPITATION: A few large areas received no rain or only light sprinkles during
e week. These include the Southwestern Deserts, the Rio Grande Valley, much

of the northern and central Great Plains, and much of Florida, Georgia, and South

Carolina. A few light snow flurries occurred early in the week from northern

Minnesota and Michigan to the Appalachians and southern New England. Marquette,

Michigan, measured 4 inches on the ground Tuesday morning. A Pacific storm

pounded the western coast in the first half of the week. Wind gusts approached

100 m.p.h. at Cape Blanco, Oregon, on Tuesday. Rainfall totals reached 2 to 4

inches or more along the Washington and Oregon coast and almost an inch along

the California coast. Showers and thunderstorms developed about midweek over

the southern Rockies and central Great Plains. Amounts were of little importance

in the Rockies but portions of the Plains recorded 1 to 2-inch totals with

isolated spots receiving much more. Lead Hill, Arkansas, received 6.50 inches

during the week. Texas, Mississippi, and Alabama reported tornadoes which

injured a few persons but property damage was mostly light.

Weather of the week continued on page 1048.

Nation while cool weather prevailed in the East. It was especially warm along
the eastern slope of the Rockies with numerous stations from western South

Dakota to the Rio Grande registering afternoon temperatures in the middle and
upper 80's on October 30. With clear skies, bright sunshine, and brisk southerly
winds, numerous stations in the central Great Plains established new high-tempera-
ture records on Wednesday. In sharp contrast, cold air brought the first hard
freeze of the season to the East. Subfreezing minimum temperatures occurred in
the Deep South on Monday morning, October 28, and in the Northeast from Tuesday
to Thursday. In the second half of the week, the temperature situation was
reversed. Cool weather invaded the West and the East warmed. On Wednesday
afternoon, North Platte, Nebraska, was 15° warmer than Tampa, Florida, on
Saturday afternoon North Platte was 30° colder than Tampa, the maximum at North
Platte having dropped from 86° to 48°. Most of the Nation averaged warmer than

WEATHER OF THE WEEK ENDING NOVEMBER 12

HIGHLIGHTS: Snow or chilling rain accompanied the cold, cloudy weather over
most of the Nation, The east coast was battered by high winds which, at a few
locations, reached hurricane force,

PRECIPITATION: A snow storm swept across the northern Rocky Mountains early in
the week. By midweek snow had fallen from the Rockies to the Great Lakes and by
Thursday had spread to New York and New England. A second storm hit New England
on Sunday and a third storm on Tuesday, November 12. The last storm, most
severe of the three, was accompanied by winds gusting to 70-80 m.p.h. off the
southeast coast causing heavy damage to utility lines, coastal installations

and shipping. A strong cold front set off scattered showers with snow in some
localities in eastern New Mexico from Wednesday to Friday. As the front crossed
Texas, it produced wet snow over the northern half of the State and cold rain
over the southern half. Most of the snow melted as it fell. Light rains fell
in the Southeast early in the week. The weekend brought heavier rains to that
area, Some previously dry sections in southern Georgia benefited from an inch
or more of rain, The moderate to heavy rains in Florida on Saturday and Monday
were accompanied by blustery winds, The Pacific Northwest received rain early
and late in the week with totals ranging from 2 to 6 inches along the coast.
Snow fell in the higher elevations in the Northwest. Arizona, southern Nevada,
and the California deserts received no precipitation,

Weather of the week continued on page 1064,

WEATHER BUREAU'S 30-DAY OUTLOOK
MID-NOVEMBER TO MID-DECEMBER 1968

The Weather Bureau's 30-day outlook for mid-November to mid-December calls for
temperatures to average below seasonal normals over most of the Nation except
for near normal averages in the Great Lakes region and coastal areas of the
Middle and North Atlantic States. The coldest areas relative to normal are
indicated as the southern Plains and the gulf coast. Precipitation is predicted
to exceed normal over the western third and eastern fourth of the Nation with
about normal amounts in between. Owing to the low temperatures predicted, some
of the precipitation over the northern half of the country and especially at
higher elevations in the West, is expected to be in the form of snow.

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 NOVEMBER 18

HIGHLIGHTS: A cold, cloudy, stormy week with subzero temperatures occurring in
the central Rockies and the Great Plains and heavy snow in the western and
eastern mountains and parts of the northern Great Plains.

-PRECIPITATION: A large storm moved up the Atlantic coast early in the week
producing generous rains in the Piedmont and coastal areas and heavy snow in

the Appalachians. Snow depths reached a foot or more in the mountains of the
Carolinas and at spots farther north in Virginia, Maryland, Pennsylvania, New
York, and New England. Winds gusted 40 to 70 m.p.h. along the middle

Atlantic coast causing heavy damage. The storm began to subside about Wednesday
and by Thursday forenoon, light flurries continued over the northern Appalachians
from Pennsylvania to New England. As the storm decreased in the Northeast, a
new storm developed in the Southwest. By Thursday morning, Some mountain roads
in Colorado had already become snow-clogged and snow was beginning to fall at
higher elevations in northern Arizona and New Mexico. Rains soaked the lower
regions and spread eastward to the Great Plains. Thunderstorms developed and

a few tornadoes occurred in the Deep South. Damage was not generally extensive
and injuries were relatively few. Weather of the week continued on page 1075.

CHANGE IN SCIENTIFIC NAME
Names of the Two-Spotted Spider Mite and the
Carmine Spider Mite to be Redesignated
Floyd F. Smith and Edward W. Baker 1/

In the most recent list of approved common names (''Common Names of Insects Approved
by the Entomological Society of America."' Ent. Soc. Amer. Bul. 11(4):290, 301,
316, 1965), the name of the two-spotted spider mite was changed from Tetranychus
telarius (L.) to T. urticae Koch, and the name of the carmine spider mite was
Changed from T. cinnabarinus (Boisduval) to T. telarius (L.). Entomologists and
acarologists Concerned with mite problems have objected to these changes because
of confusion in the literature. The changes were made in response to proposals
by Gudo Dosse and H. Bruce Boudreaux to the International Committee on

Scientific Names. G.L. van Eyndhoven concurrently made counter proposals and
arguments to the same committee. The committee, which includes G.O. Evans, had
postponed final action on the proposed changes because of the lack of agreement
among recognized specialists. At the Congress of Acarology, held in 1967 at the
University of Nottingham, England, Boudreaux and Eyndhoven came to the following
agreement in discussions with Evans and prepared a joint statement and recommenda-
tion to the committee. They now propose: (1) To retain the name T. urticae Koch
for the two-spotted spider mite, which is green; and (2) to continue the use of
T. cinnabarinus (Boisduval), which is red, as the name for the carmine spider
mite in Europe, America, and Japan. Both men believe that more than one species
of red cinnabarinus may be involved. If more than one species is found, future
designations can refer them to a cinnabarinus complex or by species names other
than cinnabarinus. This joint agreement is highly important in establishing the
identity of two economically important spider mites and averting confusion in the
literature.

Change of Name of the Strawberry Spider Mite
Edward W. Baker ays

The scientific name of the strawberry spider mite has been known almost worldwide
as Tetranychus atlanticus McGregor, 1941 (see "Common Names of Insects Approved

by the Entomological Society of America.'"' Ent. Soc. Amer. Bul. 11(4):300, 316,
1965). In 1961 B.A. Wainstein of USSR synonomyzed this species with T. turkestani
Ugarov and Nikolski, 1937. Inadequate figures and lack of Russian specimens at
that time prevented further checking by us. The late Dr. A.E. Pritchard eventually
obtained specimens of T. turkestani from southern USSR, and after long study of
those specimens I have come to the conclusion that T. atlanticus and T. turkestani
are the same species. Tetranychus turkestani Ugarov and Nikolski is the name to

be used for the strawberry Spider mite.

WEATHER OF THE WEEK ENDING NOVEMBER 25

HIGHLIGHTS: Temperatures ranged widely. Mild weather predominated over the
northern Great Plains. Freezing temperatures occurred in northern Florida.
Light to moderate precipitation fell in the East. Much of the West received no
rain.

PRECIPITATION: Rain fell along the northern Pacific coast and snow in the
Cascades on Several days during the week. Widespread precipitation also occurred
early in the week in the eastern half of the United States -- snow flurries from
the Dakotas to northern New England and southward to the southern Appalachians
and rain along the Atlantic coast from southern New England to Florida. Skies
cleared after midweek and after a day or so with only light scattered precipita-
tion, snow began falling in the western mountains. A cold front produced showers
from northeastern Texas to the Ohio River Valley on Saturday and from southern
Louisiana to New England on Sunday. At week's end a frontal system is

producing snow from the central Rockies to the northern Great Plains.

TEMPERATURE: A frigid blast of Canadian air overspread the vast region from the
Rocky Mountains to the Atlantic Ocean. By Wednesday morning the cold had
penetrated the Deep South and New Orleans, Louisiana, registered 30°. On
Thursday morning, Richmond, Virginia, and Raleigh, North Carolina, registered

20° and 18°, respectively. As the cold air moved southeastward to the gulf and
the Atlantic Ocean a warming trend began in the West. By Wednesday afternoon,
temperatures along the eastern slope of the Rockies had climbed into the 60's.
Havre, Montana, warmed to 65° on Wednesday -- 10° warmer than Tampa, Florida.

The East warmed late in the week with afternoon readings in the 60's as far north
as New York City by Sunday. Colder air was invading mid-America, however, and
afternoon temperatures on Sunday were generally in the 40's over the northern
Great Plains and the 50's from the central Great Plains to the Ohio River Valley.

WEATHER BUREAU'S 30-DAY OUTLOOK
DECEMBER 1968

The Weather Bureau's 30-day outlook calls for temperatures to average below
seasonal normals over the southern half of the Nation lying west of the
Mississippi, and also over New England. Above normal temperatures are expected
for the Ohio Valley and Southeast. In unspecified areas near normal averages
are indicated. Precipitation is predicted to exceed normal over a broad area
extending from the southern Plateau through the central Plains, Ohio Valley,
eastern Great Lakes, and Northeast. Subnormal precipitation is predicted for
the West Coast, the northern Plains, and Florida. Elsewhere near normal amounts
are 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 DECEMBER 2

HIGHLIGHTS: Winter storms struck the Rocky Mountains and most northern States.
A few tornadoes occurred in the South. Temperatures in the Rockies plunged far
below zero.

PRECIPITATION: Generous rains fell along the Pacific coast and nearby inland
valleys While snow fell above about 4,000 feet in the Cascades and about 6,000
feet in the southern Sierras. Snow is now 36 to 48 inches deep above 3,000 feet
in the Cascades. Light snow fell across the northern Great Plains early in the
week and moderate to heavy snow fell in the Rocky Mountains on several days
during the week and over the weekend. Seven inches of snow fell at El Paso,
Texas, Tuesday evening and Wednesday morning. Snow depths reached 2 to 6 inches
in the mountains in Arizona and about one foot at Cloudcroft Ranger Station,

New Mexico. By the weekend the snow belt had extended from the Rocky Mountains
across the northern and central Great Plains to northern New England. Along the
southern edge of the snow belt freezing rain mixed with the snow slicked the
highways making automobile travel hazardous. Weather of the week continued on
page 1102.

CORRECTIONS

CEIR 18(46):1068 - EUROPEAN EARWIG ... Collected ... June 7, 1968, ... should
read ... Collected ... June 17, 1968.

Weather of the week continued from page 1094.

Moderate to heavy rains fell from eastern Texas to the Great Lakes -- mostly in
the first half of the week. Flash flooding occurred along a few small streams

in Tennessee and Mississippi. A few tornadoes occurred Tuesday and Wednesday
nights in Texas and Louisiana causing mostly light damage to trees, farm buildings,
and utility lines. Precipitation occurred from Thursday to Sunday along the
Atlantic coast. Amounts were generally light to moderate.

TEMPERATURE: Above normal temperatures prevailed over most of the West early in
the week but a drop in temperatures caused the week to average colder than
seasonal. Subzero readings were common in the higher Rockies. Frazer, Colorado,
elevation about 8,000 feet, registered 33° below zero on Saturday morning.
Temperatures averaged above normal from Washington to New York and southeastward
to Florida. The Dakotas and nearby portions of neighboring States averaged 6° to
11° above normal. The East averaged warmer than normal in spite of the cool
weekend, when afternoon readings were mostly in the 40's and low 50's.

Forage Crop Insects in Massachusetts in 1968
F.R. Shaw, S. Dennis, L. Dondero, D. Miller, M. Miller, and C.P.S, Yadava

Population studies of forage crop insects were conducted from April 22 through
August 4. Limited collections were conducted subsequently, primarily to determine
incidence of alfalfa weevil and of its parasites.

Collections were made at approximately weekly intervals in Hampshire County. Some
sampling was also conducted in Berkshire, Bristol, Essex, Franklin, Plymouth, and
Worcester Counties. Each collection consisted of 100 sweeps with a 15-inch net.
The insects were identified in the laboratory and their numbers tabulated. The
following table is based on a collection of 23,149 insects.

Populations of Insects Collected on Forage Crops - 1968

Insect Name or Group Percent of Total
Pea Aphid (Acyrthosiphon pisum) 34.63
Alfalfa Weevil (Hypera postica) S222
Plant Bugs 92
Meadow Spittlebug (Philaenus spumarius) 11.48
Leafhoppers 2.33
Lepidoptera 1.05
Grasshoppers ORT
Sawflies 0.05
Beneficial Arthropods
Nabis spp. 1.60
Parasitic Hymenoptera 1200
Spiders OL 9%
Coccinellids (lady beetles) 0.72
Chrysopids 0.16
Syrphids 0.16
Pentatomids On:

In comparison with the populations observed in 1967, some rather obvious changes
occurred. For the first time in several years pea aphid (Acyrthosiphon pisum)
surpassed alfalfa weevil (Hypera postica) in abundance, doubling its 1967
occurrence. Meadow spittlebug (Philaenus spumarius) was much more numerous,
increasing from 2.7 percent in 1967 to 11.48 percent in 1968. Leafhoppers decreased
from 12.7 percent in 1967 to 2.3 percent in 1968. Nabis spp., parasitic Hymenoptera,
pentatomids, and spiders were more numerous in 1968.

In order to determine the incidences of parasitism, collections were made at
approximately weekly intervals from April 22 and were continued until low temper-
ature stopped the activity of alfalfa weevil and its parasites.

The following conclusions relative to parasitism are those of M.C. Miller:
"Bathyplectes curculionis maintained at least 80 percent parasitism of alfalfa
weevil Larvae (in fields Sampled) from May 8 through July 8 except for the period
of peak alfalfa weevil population (May 1-15) when parasitism dropped to 30 per-
cent. Tetrastichus incertus maintained a parasitism rate of less than 10 percent
from May 23 through July 12. By July 22 parasitism increased to 70 percent."

Observations were made of the preferences of Nabis rufusculus, Podisus
maculiventris, and P. placidus for alfalfa weevil larvae and for pea aphid.

The nabid preferred pea aphid whereas the pentatomids preferred alfalfa weevil
larvae. Some limited observations of the host selection of chrysopid larvae
showed these insects selected pea aphids in preference to nymphal leafhoppers and
plant bugs and to alfalfa weevil larvae.

WEATHER OF THE WEEK ENDING DECEMBER 9

HIGHLIGHTS: Winter cold advanced far southward. Subzero cold occurred in
New Mexico and hard freezes in Georgia and Florida. Heavy snow fell in the
Cascades and in lee of the Great Lakes.

PRECIPITATION: Daily rains along the northwest Pacific coast and snow in the
Cascades continued the pattern which has prevailed for several weeks and which
normally can be expected to endure until spring. Amounts exceeded 4 inches
along the coast, ranged from 2 to 3 inches in the interior valleys, to more
than 4 inches on the western slopes of the Cascades, and about 0.5 inch on the
eastern slopes. Snow depths reached 48 inches at 3,000 feet and 96 inches at
5,500 feet in the Cascades, Snow or snow flurries continued from the northern
Great Plains to New England. By Friday the snow depth at Greenville, Maine, had
reached 17 inches. Depths in New York exceeded 20 inches locally in the lee of
Lakes Erie and Ontario. Little or no precipitation fell in the Far Southwest
and along the western edge of the Great Plains from the Dakotas to the Rio
Grande. Only light snow fell in the central and southern Rockies. Light rains
fell in the Deep South and much of the East early in the week. Snow flurries
accompanied the colder weather in the East from Thursday to Sunday with depths
ranging from 10 inches locally in northeastern Ohio to an inch or so in North
Carolina.

TEMPERATURE: Subzero temperatures occurred in the central and southern Rocky
Mountains early in the week and in the northern Rockies and parts of the northern
Great Plains over the weekend. Zuni, New Mexico, registered 8° below zero on
Monday morning, December 2, and Bemidji, Minnesota, 17° below zero on Sunday
morning, December 8. Subfreezing temperatures advanced far southward into Dixie
reaching the Gulf of Mexico Monday morning, December 9, when New Orleans,
Louisiana, and Mobile, Alabama, recorded 31° and 28°, respectively. Idaho and
nearby parts of neighboring States experienced cold mornings but mild afternoons,
averaging slightly above normal. Temperatures averaged below normal elsewhere

in the West. The Great Lakes region and the Northeast averaged slightly warmer
than normal but below-normal average temperatures were general from the central
Great Plains to the gulf and eastward to the Atlantic Ocean due to the cold
weather which began about Thursday and intensified to the end of the period.

good crop in spite of pink bollworm. Expect estimated 2.5 bales per acre.
Good cultural practices of shredding, plowup, cleanup, irrigation plus host
free period, and releasing of sterile moths were apparently beneficial.
Outlook for 1969 depends on growers following recommended cultural controls.
(Cal. Coop. Rpt.). ARIZONA - Larvae averaged 55 per lint cleaner in gins at
Yuma, Yuma County. (Ariz. Coop. Sur.). NEW MEXICO - Medium to heavy during
lint cleaner inspections in 2 Eddy County gins. (Judd). About 70 percent

of larvae dead in green wet bolls in southern Dona Ana County. (Nielsen).
OKLAHOMA - Positive in lint cleaner inspections during November in additional
counties of Comanche, Harmon, Kiowa, Garvin, Stephens, Custer, and Hughes.
(Okla. Coop. Sur.).

JAPANESE BEETLE (Popillia japonica) - VIRGINIA - Larvae medium in rose border
in Prince Edward County. Determined by W.A. Allen. (Peery, Nov. 30).

HAWAII INSECT REPORT

Turf, Pasture - A GRASS WEBWORM (Herpetogramma licarsisalis) continues moderate
to heavy and spotty in various areas on Kikuyu grass, Bermuda grass, Henrys crab-
grass, Pangola grass, carpetgrass, Hilo grass, and St. Augustine grass on Kauai,

Oahu, Maui, and Hawaii; light in pastures on east Molokai. (Miyahira et al.),

General Vegetables - BEET ARMYWORM (Spodoptera exigua) and LEAF MINER FLIES
(Liriomyza Spp.) generally light in green onions at Waianae, Waimanalo, Koko Head
and Kahuku, Oahu. (Yamamoto, Sato). TARO LEAFHOPPER (Tarophagus proserpina)
heavy and Cyrtorhinus fulvus (a predaceous capsid bug) adults very evident in
taro patch at Waimea, Kauai. (Sugawa).

?

Fruits - LARGE MANGO TIP BORER (Bombotelia jocosatrix) larvae remain trace on
mango foliage throughout Oahu. Light but spreading on Kauai; found as far west
as Waimea. (Nakao, Sugawa). Larvae of a NOCTUID MOTH (Phlegetonia delatrix)
severe on mountain-apple at Pukalani, Maui; damage extremely heavy to terminal
leaves. (Miyahira).

Ornamentals and Others - BARNACLE SCALE (Ceroplastes cirripediformis) light on
gold tree (Cybistax donnell-smithi) and dwarf pomegranate (Punica granatum var.

nana) at Honolulu International Airport and on asystasia (ASystasia gangetica)
and sourbush (Pluchea odorata) on Sand Island, Oahu. All are new host records,
(Shiroma, Olson).

Forest, Shade Trees - Nymphs and adults of a PSYLLID (Psylla uncatoides) trace
to light on acacia at Waimanalo, Kaneohe, and Honolulu (Nuuanu, Kalihi), Oahu;
negative on albizzia at Honolulu. Generally light on Oahu since discovery in

March 1966, (Funasaki).

Beneficial Insects - Parasitism of Herpetogramma licarsisalis (a grass webworm)
by a MINUTE EGG PARASITE (Trichogramma Ssemifumatum) averaged 75 percent on

Mt. Hualalai, Hawaii Island, at 2,100-3,800 feet elevation; 86 percent at Hana,
Maui; and 85 percent at Kaneohe and Kaaawa, Oahu, during November. Several
larval parasites common in pastures. (Yoshioka et al.),

Miscellaneous Pests - Two live GIANT AFRICAN SNAIL (Achatina fulica) specimens
collected at Kahaluu, North Kona, Hawaii Island, and one at Poipu, Kauai, during
November. Poison bait applications and surveillance continuing. Recent heavy
rains activated populations in weed areas on Maui and Oahu and caused movement
into residences and farms. Baits necessary to protect crops in some areas.
(Yoshioka et al.). A GRASSHOPPER (Oedaleus abruptus) adult found during spot
check of known infested grassy areaS at Hickam Air Force Base, Honolulu, Oahu,
after 4 days of heavy rains. (Olson).

WEATHER BUREAU'S 30-DAY OUTLOOK
MID-DECEMBER 1968 to MID-JANUARY 1969

The Weather Bureau's 30-day outlook calls for temperatures to average below
seasonal normals in the southeastern quarter of the Nation, the Middle Atlantic
Coast States, and also the Pacific Coast States. Above normal temperatures are
indicated for northern New England, the northern Great Lakes, and the southern
Plains. Elsewhere near normal averages with large fluctuations are in prospect.
Precipitation is expected to exceed normal in the Midwest, Lake region, and
Northeast where snows will be frequent, as well as over the Pacific Northwest.
Subnormal amounts are predicted for the southern Plateau, southern Plains, and
the South Atlantic States. Elsewhere near normal amounts are 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 DECEMBER 16

HIGHLIGHTS: An intense storm paraded across the northern half of the Nation,
preceded by balmy weather, accompanied by blustering winds and driving snow,

and followed by biting cold. As the storm made its exit via the St. Lawrence
River, another in the procession of winter storms entered the Pacific Northwest.

PRECIPITATION: Rains continued along the northern Pacific coast with snow in
the mountains. Winds along the coast reached hurricane force on Tuesday,
gusting to 105 m.p.h. at Cape Blanco, Oregon. Snow accumulated to 1.10 inches
above 5,500 feet in the Cascades, As the storm moved inland, it dumped heavy
snow in the northern and central Rockies and the Great Plains. Nine inches of
snow fell at Salt Lake City, Utah, on Wednesday afternoon and evening. The snow

Weather of the Week continued from page 1136.

and the blustery winds made highway travel treacherous. Strong southerly winds
gusting to more than 60 m.p.h. kicked up the dust in the central Great Plains
ahead of the storm. As the storm approached, freezing rain and drizzle, mixed
with snow, slicked the highways, creating hazardous driving conditions. Thunder-
storms occurred some places along the leading edge of the cold air. The storm
became a severe blizzard in the northern and central Great Plains with heavy
snow, winds gusting to 50 m.p.h. or more, and rapidly falling temperatures.

Snow accumulated to 9-14 inches in Minnesota from Fergus Falls to Crane Lake, to
10-20 inches in the Adirondack Mountains in New York, and to 20-30 inches in the
White Mountains in northern New Hampshire.

TEMPERATURE: Cold air lay over the Deep South early in the week. Raleigh,
North Carolina, registered 16 degrees on Monday morning, December 9. Subfreezing
temperatures occurred in northern Florida and subzero temperatures were recorded
in New York, New England, and by Wednesday morning, in northern Pennsylvania.

In sharp contrast, southerly winds brought mild weather to mid-America,

Chadron, Nebraska, warmed to 66 degrees on Tuesday afternoon, 10 degrees warmer
than Jacksonville, Florida. The storm passage brought a quick change to the
Great Plains. The temperature at Des Moines, Iowa, fell from 64° Thursday
afternoon to 12° Friday morning. Subzero temperatures occurred from Montana to
Minnesota and in the Rockies southward to northern New Mexico. Southerly winds
brought rapid warming to the East on Thursday and Friday. New York City and
Philadelphia registered 60° on Friday. Sharp cooling accompanied the weekend
cold front with subfreezing temperatures occurring as far south as the Florida
Everglades. In parts of the East, the weather was the coldest since February,
and one of the coldest December weeks of record. (Summary supplied by
Environmental Data Service, ESSA.)

INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES

FLAT RED MITE (Cenopalpus pulcher (Canestrini and Fanzago) )

Economic Importance: The species heavily infests apple in Iran and stone fruits
in Libya. In 1959 the flat red mite was widespread on apples and pears in Turkey
where it caused much concern. Considerable damage to apple trees occurred in
Cyprus where extremely high populations were noted at 2,000-4,000 feet elevation.
An average of 100 mites per leaf has been observed on a heavily infested tree.

In some areas C. pulcher is found only on neglected apple trees. Damage to buds
and flowers of quince has been reported from Libya.

Distribution: Afghanistan, Austria, Bulgaria, Cyprus, Egypt, Germany, Iran,
Tsrael, Lebanon, Libya, Netherlands, Syria, Switzerland, Turkey, and USSR (known
only in parts of Crimea, Transcaucasia and Soviet Central Asia where it is widely

distributed).

Hosts: Apple, pear, quince, loquat, poplar, willow, damson, walnut, and dogwood

Lat Felina etal

General Distribution of Cenopalpus pulcher (Canestrini and Fanzago)

Life History and Habits: Under conditions in England females overwinter in cracks
in the bark but are active early in the spring Although they wander around on
the leaves in April, they do not completely move there until May. Egg laying
begins late in April on the bark. Later, eggs are deposited on the midrib or

leaf veins, usually underneath the leaf hairs. Oviposition continues until the
middle of July when the overwintered females die. Hatching occurs at the end of
June and nymphs mature in late July For a time males outnumber females but after
mating in August and September, the males gradually die off. Only one gener-
ation a year is recorded in England but two are known in Bulgaria.

Acarina: Tenuipalpidae No. 179 of Series

WEATHER OF THE WEEK ENDING DECEMBER 23

HIGHLIGHTS: Four winter storms brought snow, sleet, or freezing rain to most
Northern States. Generous rains fell in parts of the Deep South. Bitter cold
penetrated far southward in the intermountain Plateau and the Rocky Mountains,

PRECIPITATION: Snow diminished in the Northeast early in the week as a storm
moving along the coast of Maine lost its punch. Meanwhile, a disturbance
developed in the central Rocky Mountains and, fed by moist gulf air, blanketed
the Great Plains from the Dakotas to the Texas Panhandle and eastward to the
Great Lakes and the Ohio River Valley with heavy snow. Winds in parts of the
Central Great Plains, gusting to 60 m.p.h., piled the snow in deep drifts, closing
many roads, The near zero visibility in the blowing snow hampered the use of the
roads which remained open. By Thursday morning, snow depths ranged from 14 to 15
inches in north-central Kansas, 5 to 8 inches across Minnesota and Wisconsin, and
to 13 inches in Upper Michigan. Snow mixed with sleet or freezing rain fell along
the southern edge of the Snow belt. While this storm was most severe, a third
storm gained strength in the Far West. It produced heavy snow over the interior
sections of the West and along the coast as far south as Eureka, California, with
rain farther south along the coast. The two storms whitened all States west of
*#he Mississippi River except Oklahoma, Texas, and the southern portions of
California and Arizona. After leaving heavy snow in the central and southern
Rockies, this third storm moved to the Great Plains where it dumped from 1 to 2
feet of snow from the central Great Plains to Upper Michigan. It became a howl-
ing blizzard and the 60 m.p.h. winds in the northern Great Plains whipped the
snow into drifts from 4 to 10 feet deep at many places and to 20 feet deep at a
few places, While the blizzard was raging in the Great Plains, moving toward
Wisconsin, a fourth storm produced 60 to 90 m.p.h. winds and heavy rain along the
Washington and Oregon coast, and heavy snow over much of the Northwest.

TEMPERATURE: Temperatures plummeted far below normal over most of the western
half of the Nation. Nevada, Utah, and the Rocky Mountain States averaged 10° to
15° below normal. Slight warming occurred over the eastern half of the United
States during the week, followed by weekend cooling. A wide band from eastern
Texas to the Great Lakes averaged Slightly above normal. The slow warming in the
East was insufficient to offset the earlier cold weather. The eastern States
from Alabama and Florida to southern New England averaged slightly cooler than
normal. (Summary supplied by Environmental Data Service, ESSA.)

Adult European Cherry Fruit Fly Detection Survey in Wisconsin
Philip W. Smith 1/

A cooperative Federal and State survey was conducted during 1968 in the major
sour cherry commercial orchard area of Wisconsin which included the northern

part of Kewaunee County and all of Door County. The main objective of the

survey was to detect adults of European cherry fruit fly (Rhagoletis cerasi (L.)),
if present. This damaging pest of cherry fruit in Europe 1s commonly intercepted
at U.S. ports of entry by Plant Quarantine inspectors. During June, July, and
August, 240 sticky traps using ammonium carbonate bait were hung in cherry trees
at 59 locations and serviced. A total of 4,131 flies were examined. No

R. cerasi was found but cherry fruit fly (R. cingulata (Loew)), black cherry
fruit fly (R. fausta (O.S.)), and apple maggot (CR. pomonella (Walsh)) were
caught.

Determinations of R. cingulata in 1968 are the first authentic records of cherry
fruit fly for Kewaunee County (Casco Township) and the townships of Liberty
Grove and Washington Island in Door County.

Determinations of black cherry fruit fly in 1964 and 1965 exist for the townships
of Sturgeon Bay and Egg Harbor, respectively, but 1968 determinations of this
species are new records for Liberty Grove and Gibraltar Townships in Door County.

The determination of Paroxyna albiceps (Loew) (a tephritid fly) from Door County
constitutes a new record for Wisconsin. Rivellia melliginis (Fitch) (a
platystomatid fly) and Pseudotephritis vau ay) (an otitid fly) were trapped in
Door County for new county records. a

Aside from the new distribution records and the failure to detect R. cerasi in

the State, information gained from the survey will be a factor in establishing
changes in cherry insect control recommendations in Wisconsin for 1969,

INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES

CABBAGE CATERPILLAR (Crocidolomia binotalis Zeller)

Economic Importance: This species was one of the worst pests of cabbage, mustard,
and other related plants in the Philippine Islands in 1925. Often whole plots
were destroyed. C. binotalis larvae were especially damaging to cabbage, cauli-
flower, turnip, and radish in the Cape Province area of the Republic of South
Africa in the same year. The larvae prefer to feed on the succulent young
leaves and buds. The plants are severely mutilated, stunted, or completely de-
voured. The larvae also bore into the heads of cabbage and feed inside until
time to pupate. Young larvae feed gregariously on the lower leaf surface and
soon scatter over the plants, spinning a thick web over the part being fed upon.
Large holes are eaten in the leaves and the crown or heart is riddled. Leaf
edges are often scalloped.

Distribution: Australia (Queensland), Burma, Ceylon, Congo (Kinshasa), Fiji
Islands, Ghana, Guam, India, Indonesia, Kenya, Malagasy Republic, Malawi, Mariana
Islands, Mauritius, New Caledonia, New Guinea, Nigeria, Norfolk Island, Pakistan,
Philippines, Republic of South Africa, Saudi Arabia, Senegal, Seychelles, Sierra
Leone, Solomon Islands, Somalia, Southern Rhodesia, Sudan, Taiwan, Thailand,
Tonga, Uganda, Viet-Nam, Zambia, and Zanzibar.

Hosts: Cabbage, cauliflower, Chinese cabbage, Chinese radish, India mustard,
mustard, radish, turnip, other crucifers, nasturtium, and various flowering
plants.

General Distribution of Crocidolomia binotalis Zeller

Life History and Habits: The biology under conditions in the Philippine Islands
is aS follows: Eggs are laid in clusters of 21-101 in a scale-like arrangement
on the lower leaf surface. Hatching occurs in 3-5 days and the young larvae
begin to feed on the leaves. Larval development includes 4 instars and lasts
about 11 days. Full-grown larvae dig into the soil and then pupate in earthen
cells. Adult emergence takes place 6-8 days later. Moths are attracted to
lights at night but hide under leaves during the day. There may be 3-4 gener-
ations during the cabbage-growing period of 95-140 days.

Lepidoptera: Pyralidae (Pyraustinae No. 180 of Series
