WEATHER BUREAU'S 30-DAY OUTLOOK
JULY 1967

The Weather Bureau's 30-day outlook for July is for temperatures to average below
seasonal normals over the eastern two-thirds of the Nation except for near to
above normal in the southern Plains and the gulf coast region. West of the Con-
tinental Divide above normal temperatures are indicated except for near to below
normal along the Pacific coast and in the Northwest. Elsewhere near normal tem-
peratures are in prospect. Precipitation is expected to exceed normal over the
central Plains, the middle Mississippi Valley, the Pacific Northwest coast, and
along the Atlantic seaboard. Below normal totals are indicated over the Far
Southwest and in the gulf coastal region. Near normal amounts are expected 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.

EUROPEAN CORN BORER (Ostrinia nubilalis) - RHODE ISLAND - Appearing on corn in
Cranston, Smithfield, and Cumberland. (King). NEW YORK - Peak emergence June 19
and 23. Beating hedgerow weeds yielded fewer moths than previous week. Moths
still seen in corn rows. In untreated early variety trial in midwhorl stage June
22 at Accord, 23 plants in 100 showed etching or pin holes. Borers entering
florets of enclosed tassels. In earliest plantings first treated in mid-June
control seems satisfactory. (N. Y. Wkly. Rpt., June 26). DELAWARE - Adults
averaged 1 per night in blacklight trap in Sussex and New Castle Counties. Pupae

of plants in several fields in Frederick and Wicomico Counties. (U. Md., Ent.
Dept.). VIRGINIA - Second and third instars infested 90 percent of corn in
35-acre Campbell County field. (Isakson, Ellis). Light trap studies past 9
years indicated peak moth flights for second and third broods should occur

about July 5 and August 15, respectively, at Painter on Eastern Shore. In-
dications are that emergence will be so staggered this year that 7 to 10-day
treatments will be necessary to protect peppers, field peas, and other susceptible
crops until end of season. (Hofmaster). OHIO - First larval occurrences of
season on corn reported from Adams and Darke Counties. (Blair et al.).

MICHIGAN - Egg laying heavy June 22 on field corn 30-36 inches high; on sweetcorn
over 36 inches high; eggs laid June 13 hatched, borings noticeable. Leaf damage
less than 75 percent in southwest June 23. (Janes) . INDIANA - Approximately

30 percent of field corn in southern third of State 40 inches or taller. Whorl
feeding and midvein entrances on 4-60 percent (average 24) of plants checked.
Only leaf feeding observed north of U. S. Highway 50; leaf feeding and midvein
damage found south of Highway 50. (Matthew, Huber). Infestations on early sweet
corn in silk stage averaged 70 percent in sandy soil areas of southwestern and
south-central areas; 4 third to fourth: instars per stalk, with 30 percent of
tassels cut. (Huber). In west-central district field corn 36 inches or taller,
egg masses ranged 0-3 per 25 plants, (averaged 1). (Huber). IOWA - Adults
continue in blacklight traps. (Mast). Adult emergence 100 percent at Ankeny,
Polk County. Leaf feeding by first to third instars ranged from 50 percent at

Ankeny to 35 percent at Spencer, Clay County. (Brindley). MISSOURI - Leaf
feeding ranged 0-14 percent in northwest fields; as high as 60 percent in some
fields. Adult emergence started in southeast area. (Jones). ALABAMA - Several

larvae per cornstalk in St. Clair County field. (Jackson). SOUTH DAKOTA - First
adults of season at light trap in Brookings, Brookings County, June 26.
(Uhlken).

WEATHER OF THE WEEK ENDING JULY 3, 1967

HIGHLIGHTS: Cool, wet week east of the Rockies. Numerous severe local storms in
midcontinent area. Dry and sunny Far West.

PRECIPITATION: From central and lower Great Plains and upper Mississippi Valley
eastward, almost daily thunderstorms in some sections and on 2-4 days in others
produced weekly total precipitation of 0.5-2 inches generally. Locally, much
heavier totals reported, such as 9.32 inches at Dardanelle, Arkansas. Some sec-
tions received less than 0.25 inch,mainly eastern New England, the middle Atlantic
coast, extreme southern Texas, and the extreme lower Ohio Valley. From the west-
ern Great Plains westward, precipitation was generally very light, although mod-
erate to heavy amounts occurred locally in the higher Rockies. Thunderstorms

with damaging wind and hail were numerous in the midcontinent area. A few torna-
does also occurred, although no deaths or unusually heavy damage were reported.

TEMPERATURE: Temperatures for the week averaged 6° to 9° above normal in interior
sections of California and Oregon and a few degrees above elsewhere west of the
Continental Divide. Maximum temperatures at the end of the period rose to 100°
as far north as southern Washington. In California's southeastern desert, Death
Valley reported 123° and Needles 122° on July 2. East of the Continental Divide
the week was generally 2° to 4° colder than normal but slightly warmer than nor-
mal in gulf coastal areas and extreme northern New England. Cool weather in
northern Sections was caused by cool Canadian air intrusions at the beginning and
end of the week while cloudiness and showers were the main factors in southern
interior areas. In North Dakota minima in the 30's and scattered frost occurred
over the weekend. Warmest weather occurred in the midcontinent area on the 29th
when maxima reached the 90's in North Dakota, and in the East on the 30th when
maxima in the 90's extended as far north as Pennsylvania. (Summary supplied by
Environmental Data Service, ESSA).

WEATHER OF THE WEEK ENDING JULY 10, 1967

HIGHLIGHTS: Wet week in much of South Central and Southeast with widely scattered
heavy thundershowers. Cool Central areas and East became hot and humid at weekend.

PRECIPITATION: Little rain of importance fell west of Continental Divide. One
exception was Flagstaff, Arizona, which received 1.80 inches. Spots in northern
Great Plains and Great Lakes region received Showers, but amounts were extremely
variable and averages were generally well below normal. Texas continued

extremely dry in south and central portions but this was seventh Sshowery week for
the High Plains. The central Great Plains, much of Dixie, and the East from
Florida to Maine received rains but amounts ranged widely. Parts of Louisiana
received first substantial rains in 4 weeks - over 6 inches at Alexandria. About
6 inches fell at Hot Springs, Arkansas. Totals in North Carolina ranged from
light sprinkles to 7 inches with averages near 2 inches. More than 8 inches fell
at Moberly, Missouri, in a heavy Sunday shower. It was the second wet week in
Tennessee where spots received up to 6 inches. Showers fell almost daily in West
Virginia; soil moisture there best in Several years. The Northeast received
general rains on Monday and weekend showers. Spots in Pennsylvania, New York, and
southern New England received 2 to 3 inches.

SPECIAL INSECTS OF REGIONAL SIGNIFICANCE

ARMYWORM (Pseudaletia unipuncta) - DELAWARE - Adults averaged 8 per night in
blacklight trap collections in Sussex County. (Burbutis). MARYLAND - Adults in-
creasing in blacklight traps on Eastern Shore; averaged 15 per night week ending
July 4 at Snow Hill, Worcester County. (U. Md., Ent. Dept.). MAINE - No larval
activity reported to June 30. (Boulanger).

CORN EARWORM (Heliothis zea) - IDAHO - First observed July 5 damaging sweet corn
tassels, still in leaf whorls of early variety home plantings near Parma, Canyon
County. Too early to estimate potential damage. (Waters). TEXAS - Moderate to
heavy in heads of grain sorghum in Johnson, Hill, Delta, Jackson, and Limestone
Counties. Larvae 3-6 per head in about 50 percent of heads examined near
Cleburne, Johnson County; 3-4 per head in several Hill County fields, 5-10 per 20
heads in Delta County. Infestations much higher this year than previously.
(Smith et al.). KANSAS - Occasional larva in alfalfa in north-central and north-
east areas; less than 2 per 10 sweeps. (Simpson). MARYLAND - Few adults taken in
blacklight trap at Snow Hill, Worcester County. (U. Md., Ent. Dept.). NEW

JERSEY - Many growers applying sprays to Sweet corn every 3 days to prevent
injury. (Ins.-Dis. Newsltr.).

CORN LEAF APHID (Rhopalosiphum maidis) - ILLINOIS - Heavy in occasional field of
pretasseling sweet corn in west-Southwest Section; occaSional in early maturing
field corn week ending June 30. Found in whorls of corn in southern half of
State. Occasional field 100 percent infested; heavy in 10-15 percent of plants.
Found in northern half of State. Individual aphids found in whorls. Many winged
forms indicate migration occurring. Foxtail, Johnson grass, and other grasses
infested. (Ill. Ins. Rpt.). NEBRASKA - Heavy in sorghum. About 90 percent of
plants infested in fields checked in Saline and Nemaha Counties. Natural control
agents increasing rapidly. (Keith). KANSAS - Populations variable in corn and
sorghum in central, north-central, and northeast areas. Ranged 0-200 per whorl
in many fields. (Simpson). OKLAHOMA - Averaged 400 per whorl in sorghum checked
in Jackson County. (Okla. Coop. Sur.). UTAH - Heavily infested 20 acres of barley
at Avon, Cache County. (Knowlton). NEVADA - Populations of this species and
Macrosiphum avenae reduced on grain in Lovelock, Pershing County, by insecticides

and predators. (Lauderdale).

GREENBUG (Schizaphis graminum) - NORTH DAKOTA - Populations increased in east-
central and Southeast counties due to cool temperatures. Ranged 30-800 per 100
sweeps (average 280) on oats, wheat, and barley in Traill, Cass, and Ransom
Counties. Highest counts on oats in Ransom County. Parasite and predator popula-
tions low. (Brandvik). MINNESOTA - Generally low, but up to 2,000 per 100 sweeps
in Some oat fields in Dodge and Goodhue Counties. Damage evident. Predators
generally low to moderate in most grain fields. (Minn. Ins. Sur., June 30).

POTATO PSYLLID (Paratrioza cockerelli) - COLORADO - Populations low in 17 potato
fields in Otero, Bent, and Prowers Counties; 0-2 per 100 sweeps. None found in
fields in San Luis Valley area. Winged adults 0-100 per 100 sweeps on matrimony-
vine. Numbers high in southern part of valley. (Schweissing, Jenkins).

POTATO LEAFHOPPER (Empoasca fabae) - MISSOURI - Counts in alfalfa in west-central
area ranged 40-1,000+ adults and nymphs per 10 sweeps; some yellowing observed.
(Munson). ILLINOIS - Average counts per 100 sweeps week ending June 30 as
follows: 285 in northeast, 185 in northwest, 125 in west, and 500 in central
section. Damaged alfalfa in southern third of State. Averaged 9 per sweep in
central section and 6 per Sweep in northwest section week ending July 7. Yellow-
ing of alfalfa observed in central and southern sections. (Ill. Ins. Rpt.).
WISCONSIN - Common in alfalfa throughout southern area. In Rock, Dane, Columbia,
Dodge, and Marquette Counties, nymphs averaged up to 1 per sweep. (Wis. Ins.

Sur.). INDIANA - Adults and nymphs numerous on alfalfa in central, east-central,
and northeastern districts. Adults ranged 1-8 (average 2) and nymphs 1-7

weather over most of State and daytime temperatures of 90-98° last 15 days ex-
tremely favorable for weevil buildup. Survival of larvae, pupae, and young adults
very high. High numbers of overwintered weevils entering northern area fields.
Heavy "hatchout" and presence of overwintered weevils along with weather condi-
tions resulted in one of largest and most damaging populations for time of year
that has been experienced in several years. Continuing rains and wet fields
hampering controls. (McQueen). MISSISSIPPI - Punctured squares found in 9 of 18

WEATHER BUREAU'S 30-DAY OUTLOOK

MID-JULY TO MID-AUGUST 1967

The Weather Bureau's 30-day outlook for mid-July to mid-August calls for tempera-
tures to average below seasonal normals over the eastern half of the Nation except
for near normal along the gulf coast and in northern New England. Above normal
temperatures are indicated over the western third of the Nation except for near
normal along the west coast. The area of most unsSeaSonable coolness is indicated
over the middle Mississippi and Ohio Valleys while the area of most unseasonable
warmth is expected to be over the central Plateau in the West. Near normal tem-
peratures are anticipated in unspecified regions. Precipitation is expected to
exceed normal over a broad area embracing the central Plains, the southeast quarter
of the Nation, and the middle and north Atlantic coasts. Subnormal amounts of
rainfall are indicated for the Great Lakes region, Southern Texas, California, and
the northern Rockies. In unspecified areas near normal amounts are predicted.

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 24, 1967

HIGHLIGHTS: Continued dry, Pacific coast; light to moderate showers most other
areaS. Cool with warming trend becoming hot by weekend.

PRECIPITATION: Many areas from Rocky Mountains to Atlantic coast received light
rains early in the week and light to moderate showers over the weekend. Thunder-
showers hit Texas High Plains for 9th consecutive week. Some previously dry areas
of Texas received 4 to.8 inches from the thunderstorms, some of which were accom-
panied by damaging hail and wind. Many widely scattered spots over eastern half
of the Nation received heavy weekend Showers. Showers fell almost every day over
most of the Atlantic Coastal States, some being accompanied by damaging wind and
hail. Wide areas in Washington, Oregon, California, and western Nevada received
no rain. Most of Washington and the lower Rio Grande Valley in Texax suffered
from lack of rain.

TEMPERATURES: Temperatures averaged in the 70's over most of the Nation. Aver-
ages were generally slightly below normal except over the northern Great Plains
and most of New England. Minnesota averaged warmer than normal after 4 weeks of
cool weather and it was the warmest week of Summer in Iowa. Cool temperatures
prevailed over much of the Nation early in the week. Gradual warming brought
daily temperatures above normal by the weekend when afternoon temperatures from
the coastal ranges in the Far West to the Mississippi River were mostly above 90°,
and readings in the high 80's were common from the Mississippi eastward. With
warmer temperatures came increased humidity which made high temperatures more
noticeable. (Summary supplied by Environmental Data Service, ESSA).

92 taken in one black light trap on east Wareham cranberry bog, Plymouth County.
(Crop Pest Cont. Mess., July 14). MARYLAND - Adults very heavy in blacklight
traps on Eastern Shore; averaged 376 per night week ending July 18 at Snow Hill,
Worcester County. (U. Md., Ent. Dept.). OHIO - Large flight July 6-19. Second-
generation larvae may be numerous enough next month to cause some damage. (Rose).
WISCONSIN - Second to fifth instars light in lodged oats in Dane County, light
damage to corn. (Wis. Ins. Sur.). NEBRASKA - Light on corn in Dawson County.
(Pruess, July 14). COLORADO - Adults increased in light trap in Weld County.
(Engle et al.).

ASTER LEAFHOPPER (Macrosteles fascifrons) - WISCONSIN - As of third week in June,
aster yellows index 8 percent. lLeafhoppers continue high on lettuce and other
crops. Aster yellows occurred in one field despite spray program of 3 times
weekly. (Wis. Ins. Sur.). MICHIGAN - Heavy throughout State. (Bath, Janes). MIS-—
SISSIPPI - Light on most grasses in cornfields. (Dinkins).

BEET LEAFHOPPER (Circulifer tenellus) - WASHINGTON - Nymphs numerous on sugarbeets
throughout State. Some curly top on beets and tomatoes in home gardens in Browns-
town, Yakima County. (Landis, July 17). CALIFORNIA - Inspection of tomatoes in
Tulare and Kern Counties completed. Curly top incidence less than one percent in
tomato-growing areas of Tulare County; approximately 8,000 plants checked in
numerous small patches totaling 191 acres. Tomatoes in Kern County not severely
infected probably due to heavy beet leafhopper population on large Russian thistle
acreage in county. Population averaged 150 per 10 sweeps on thistle between
Maricopa and Mettler in the San Emidio area. (Cal. Coop. Rpt.). COLORADO - Remains
low, O-3 per Square foot, in Mesa, Montrose, and Delta Counties. Culy top low in
fields; ranged 0-3 percent per 100 plants. (Bulla).

in Greer and Love Counties. Moderate in peanuts in Bryan County; light to moder-
ate in corn in Garvin County. (Okla. Coop. Sur.). ARKANSAS - Light in few fields

in southwest area. Increasing on grain sorghum in Miller County. Infested
fields in late bloom to early dough stage. In one field of broadcast Sorghum, 31
larvae found in 25 heads. In grain sorghum planted in rows, larvae ranged 29 to

75-80 per 10 row feet. Semi-open heads have twice the number of larvae of com-
pletely open heads. (Ark. Ins. Sur.). TEXAS - Larvae heavy in peanut field near
Grapeland, Houston County; about 50 percent defoliation. Larvae numerous on pea-

tassels of sweet corn in Cape May County. (Ins.-Dis. Newsltr.). MARYLAND - Light,
developing rapidly on tasseling corn in Several areas on Eastern Shore. (U. Md.,
Ent. Dept.). OHIO - Present over most of State. If populations build up before
tassels well emerged, much interference with pollination may occur, resulting in
barren ears. Corn development slow; height July 17 averaged 38 inches, 7 inches
below normal for date. (Ohio Crop and Weather Bull.). Widespread, light popula-
tions potential threat to corn crop. Infested all of grain sorghum at one

WEATHER BUREAU'S 30-DAY OUTLOOK AUGUST 1967

The Weather Bureau's 30-day outlook for August is for temperatures to average
below seasonal normals over the eastern two-thirds of the Nation except for near
normal along the Atlantic Seaboard and in the Northeast. Above normal tempera—
tures are expected west of the Continental Divide while near normal averages are
indicated in unspecified areas. Precipitation is expected to exceed normal over
the East Coast States and also the South. Subnormal totals are in prospect for
the western quarter of the Nation, the northern Plains, and the northern
Mississippi Valley. Elsewhere near normal precipitation is indicated.

Weather forecast given here is based on the offical 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.

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's 30-day Outlook will be normal. Therefore the
forecasts given below cannot be viewed with the same degree of confidence as
those in the "Insect and Disease Summary" usually released twice each month by
this station.

CITRUS RUST MITE (Phyllocoptruta oleivora) will increase in July and subside
after mid-August. Population will be in high range during that period. Mites
expected to be above average abundance through September. Heavy infestations
will develop on fruit in about 20 percent of groves. TEXAS CITRUS MITE
(Eutetranychus banksi) and CITRUS RED MITE (Panonychus citri) will decrease
rapidly after mid-July and be at low level by September. Only scattered in-
festations will be important. BLACK SCALE (Saissetia oleae) will remain at high
level through July then gradually decrease to low level by September. New genera—
of crawlers will appear late in August but are not expected to be of much

=) 109} =

importance this year. GLOVER SCALE (Lepidosaphes gloverii) will continue in high
range through July, decrease to low level in August then gradually increase in

Tevel until mid-September. None expected to be very troublesome. MEALYBUGS will
decrease from high range by end of July and gradually decrease to low level
through September. WHITEFLIES will be moderately numerous but below normal
abundance. Decrease expected through August followed by gradual increase in
September. (W. A. Simanton).

Estimates of Damage by the European Corn Borer
to Grain Corn in the United States in 1966

Compiled in Survey and Detection Operations, PPC, ARS

The loss to grain corn, attributed to the European corn borer (Ostrinia nubilalis)
in 1966 is estimated to be approximately 121,236,000 bushels in 14 corn-producing
States. In these States the loss was 3.38 percent of the production. This loss

is approximately 2.95 percent of the total national crop estimated at 4,121,100,000
bushels. 1/ The value of the loss, based on the season average prices received

by farmers for corn 2/, is $155,876,000. These loss estimates are only for the
States shown in Table 1, and are based on the counties or districts surveyed dur-
ing the fall of 1966 within these States. 3/

Table 1 is a composite of State and Federal estimates. These estimates were pre-
pared by using production data 1/, and prices received 2/, released by the Statis-
tical Reporting Service. The basis for the loss estimates was determined by the
Survey of European corn borer populations during the fall of 1966. 3/ The index
of 3 percent loss per borer per plant was used to compute the loss in bushels.

Estimated losses to grain corn for the past 15 years in States where the fall
abundance survey waS conducted are as follows:

WEATHER OF THE WEEK ENDING AUGUST 7, 1967

HIGHLIGHTS: Generally cool and showery weather continued in much of Central and
East; flash flooding in parts of East and Southeast.

PRECIPITATION: Weather in most of Far West and in central and southern Texas
continued dry. Montana soils are becoming dry and dry thunderstorms set
numerous forest fires in Idaho. Strong winds stirred up dust in irrigated
valleys of Arizona, Elsewhere over Nation, afternoon and evening thunderstorms
brought mostly light to moderate rains, but a few spots received heavy thunder-
showers with damaging flash floods. Extensive flood damage occurred in Greens-
burg, Kentucky, area. Heavy thundershowers during August 3-5 caused local
flooding along Maryland's central Eastern Shore and in southern Deleware where
weekly totals ranged 9-11 inches. Much of New Jersey received heavy rains last
week; some areas have received 7-11 inches of rain in past 4 weeks. Frequent
moderate to heavy thundershowers in areas of New York and Pennsylvania. [In the
South, thunderstorms dropped 4 inches or more of rain in local areas in Arkansas,
western Tennessee, and coastal areas of Mississippi and Alabama.

TEMPERATURE: This was the second warm week west of the Continental Divide. Parts
of the Great Basin, New Mexico, and Texas averaged 3°-8° warmer than normal.
Cooler-than-normal weather prevailed over northern and central Great Plains, the
Southeast, the Lakes region, the Ohio Valley, and New England. It was the sixth
to ninth cool week over much of mid-America. However, temperatures did reach

100° as far north as Bismarck, North Dakota. Cool weather dropped temperatures
over the middle of the Nation to comfortable levels at midweek. Bismarck
registered 47° Wednesday morning. The East was hot and humid early in week but
moderated some during latter half. (Summary supplied by Environmental Data
Service, ESSA).

INSECTS NOT KNOWN TO OCCUR IN CONTINENTAL UNITED STATES

NEW GUINEA SUGARCANE WEEVIL (Rhabdoscelus obscurus (Boisduval))

Economic Importance: The weevil, described in 1835, is one of the more important
pests of Sugarcane in Hawaii. Formerly, it caused annual losses of over a half

a million dollars in that State. After 1910, when the tachinid parasite Lixophaga
sphenophori (Villeneuve) was introduced into Hawaii, losses were greatly reduced.
Although the parasite was effective for a time in Fiji, it failed to control
Rhabdoscelus obscurus by 1935. Severe losses to sugarcane in Fiji have been re-
corded. New Guinea Sugarcane weevil mines the stems of healthy coconut trees and
causes the clusters to fall.

Distribution: Australia, Indonesia, Japan (in greenhouse), Taiwan, United States
(moncontinental--Hawaii). Pacific Islands: American Samoa, Bonin, Caroline,
Christmas, Cook, Fiji, Gambier, Guam, Marshall, New Britain, New Caledonia, New
Guinea, New Hebrides, Ryukyu, Solomon, Tahiti, Tonga, and Western Samoa.

Hosts: Sugarcane, coconut, sago-palm, royal palm, toddy fishtail palm (Caryota
urens) and banana.

General distribution of (Rhabdoscelus obscurus (Boisduval) )

Life History and Habits: The female, which may live for over a year deposits 600
or more eggs in Small cavities drilled in the stalk. Eggs hatch in about 6 days
and larvae bore into the stalk where they construct extensive tunnels. Nearly

80 days are required for larval growth but only 8-14 days are needed for the
pupal stage. Pupation takes place in a cocoon which is located near an exit hole
made by the larva. The adult remains in the cocoon for several days to harden.

Coleoptera: Curculionidae No. 166 of Series

- 750 -

Description: ADULT - Large, length 12-14 mm. Body predominantly reddish to
reddish brown, head darker. Pronotum with a medium black stripe extending from
near the apex almost to base. Less distinct black marks on middle of elytra,
Sides of thorax and undersides of body. Antennae with distal pilose part of last
Segment conspicuously wedge-shaped. Female with curved, long, smooth, cylindrical
rostrum. Male rostrum curved, stouter and roughened underneath by two rows of
blunt teeth. LARVA - (Full grown) - Length about 15 mm. Footless and wrinkled.
Hard brown head and whitish body. Sparsely covered with fine stiff hairs. EGG -
Length 1-2 mm. Ivory white, slightly curved.

WEATHER OF THE WEEK ENDING AUGUST 14, 1967

HIGHLIGHTS: Continued cool Central; very cool week Central and East. Heavy
Showers southern Rockies and in Southeast.

PRECIPITATION: Heavy local showers fell early in week in central and southern
Rocky Mountains. Portions of New Mexico received heaviest rains of season;
several stations recorded more than 3 inches. A cold front brought heavy local
rains to central Great Plains and Ohio River Valley in first half of week and to
Atlantic coast over weekend. A 4-inch downpour in 1 hour on Tuesday caused local
flooding at Henderson, Kentucky. Scattered local showers brought more than 3
inches to parts of Tennessee and Mississippi. Rains were light over the
Appalachians but totaled several inches along the southern and middle Atlantic
coast. Spots in Florida received more than 8 inches and western New York
received the heaviest rains in about 3 months. In the Far West the usual summer
dry season has been accentuated. California's rain included only light showers
in southern deserts and mountains. Many stations in Oregon have received no rain
in 7 weeks and rains in Washington have been light. The fire hazard increased

in Washington and Idaho with many forests closed in the former State. In Alaska,

heavy rains have caused severe flooding in Fairbanks and the Tanana drainage
area.

Weather continued on page 776.

INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES

Oriental Hornet (Vespa orientalis L.)

Economic Importance: The oriental hornet, an omnivorous feeder and a Serious
pest, attacks ripening fruits of all kinds, especially grapes, dates and peaches.
Up to 50 percent damage to ripe fruit has been reported from Afghanistan. At
times, dates may be saved only by covering them with paper bags. Adults gnaw the
bark of young trees mainly for the construction of nests. A massive outbreak of
hornets occurred in Israel in 1934, when considerable damage of this type was
reported on citrus, grape, stone and pome fruits. The hornets kill honey bees
and have wiped out entire apiaries in Israel. In Egypt the number of Vespa
orientalis visiting an apiary observed from 1949-1955 averaged 18,947 per year.
They also feed on honey in the hives. In both Egypt and Israel, they are re-
garded as major pests of apiaries. The oriental hornet has a vicious sting and
is eSpecially troublesome to workers in vineyards.

Distribution: Afghanistan, Arabia, Egypt, Ethiopia, India, Iran, Iraq, Israel,
Lebanon, Pakistan, southern Europe, and Turkey.

Hosts: Various fruits including grapes, dates, peaches and citrus.

PIA APA AAA

Life History and Habits: The nests, generally built in the soil in Israel,
consist of 2-6 layers of combs and lack the paper cover, which generally surrounds
the combs of wasps. Occasionally, nests are found in corners of windows and in
mud walls. In Egypt, mud walls seem to be preferred and if part of the nest is
exposed, it is protected with a gray paper-like covering. Colonies die out in
November before their earth-nests are destroyed by the winter rains. The males
and workers die; only the queens hibernate. Young queens hibernate soon after
Mating. Observations in Egypt indicate that the queen may appear aS early as
February and will feed on flowers. About the end of April, as soon as weather is
favorable, she constructs a nest in which she lays eggs and feeds the first brood
of workers. The colony grows Slowly at first and workers appear early in June.
Queens begin to oviposit again after July in Egypt. The first several broods
consist of workers while those in October and November consist of virgin females
and drones. Drones sometimes occur in the nest also in late Summer.

Hymenoptera: Vespidae No. 167 of Series

- 778 -

Description: ADULT. - Head hairy, red-brown, enlarged behind the eyes; the area
between antennae and clypeus yellow; maxillae yellow with black margins. Thorax
and legs hairy, red-brown. Wings reddish-brown. Abdomen red-brown, but slightly
darker than head and thorax; first tergite with narrow yellow band, third and
fourth tergites with wider bands; second tergite with small, yellow triangle on
each side. The castes may be distinguished as follows: Male - Antenna 13-
jointed, with two small humps on the ventral side of each joint. Abdomen with

7 segments and 13-15 mm. long. Female (and worker): Antenna 12-jointed with no
humps on the lower side of each segment. Abdomen with 6 segments only and 11-12
mm. long in the worker. The female larger than the worker. Body length: Male
24-28 mm., female 26-34 mm., and worker 19-23 mm. In the field, this species
resembles the introduced giant hornet (Vespa crabro germana) which occurs in the
Eastern United States.

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

The Weather Bureau's 30-Day Outlook for mid-August to mid-September calls for
temperatures to average below seasonal normals from the Continental Divide
eastward to the Appalachians as well as in portions of the southern Rockies

and in the gulf coast region. Above normal temperatures are indicated over the
Far West and also in the middle and north Atlantic Coast States. In areas not
specified near normal temperatures are anticipated. Precipitation is expected
to exceed normal over the eastern third of the Nation and also the west gulf
coast region. Subnormal amounts are indicated in the Pacific Coast States as
well as over the northern Plains and the northern Mississippi Valley. In other
areas, near normal amounts of rainfall are indicated.

Weather forecast given here is based on the offical 30-day ''Resume and Outlook"
published twice a month by the Weather Bureau. You can subscribe through the
Superintendent of Documents, Washington, D. C. 20250. Price $5.00 a year.

HIGHLIGHTS: Floods caused $200 million damage in Fairbanks area. Continued hot
and dry in Far West. Cool with scattered showers most of Central and East.

PRECIPITATION: Rains diminished in central Alaska and at Fairbanks and Nenana

the water receded after flood disaster there. Early week showers were generally
light and widely scattered from southwestern deserts to the Great Plains. Weekend
thunderstorms brought moderate to heavy scattered showers in central and eastern
United States. Most weekly totals were less than 1 inch but a few localities in
Texas, Arkansas, along the gulf coast, and the Atlantic coast received more than

3 inches. The Far West continued extremely dry. No appreciable rains fell in
Montana. Dry thunderstorms started over 200 firés in Idaho's forests and ranges.
Many stations in Oregon have received no rain Since June 22 making this longest
dry spell on record.

TEMPERATURE: Hot weather has continued west of the Rockies for 5 weeks. Pendleton,
Oregon, registered 101° to 105° each afternoon, but at coastal locations, onshore
winds held afternoon readings to the 60's and 70's. East of the Rockies, high
pressure, clear skies, widespread sunshine, and cool temperatures prevailed.

Many central areas averaged 6° to 10° cooler than normal for second week. In
parts of central and eastern United States, this was ninth cool week. Early in
week, 90° maximums were common over the western Plains. As weekend approached,
polar continental air pushed into the northern Plains dropping temperatures into
40's on several mornings. Frost occurred in some mountain valleys in Colorado
and scattered low places from South Dakota to western Upper Michigan. As cold
air marched southward, the temperature at Springfield, Missouri, fell from 92°

on Thursday afternoon to 47° Sunday morning. Afternoon temperatures reached

the 90's far up Atlantic coast on Saturday afternoon--90's at Philadelphia--but
remained in the 60's in the middle Mississippi Valiey--63° at Moline, Illinois.
By Sunday, cool air had advanced far southward and eastward with afternoon

INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES

TWO-SPOTTED CITRUS PSYLLID (Spanioza erythreae (Del Guercio))

Economic Importance: The two-spotted citrus psyllid causes conspicuous pitting
and curling of citrus leaves on the east coast of Africa, from Ethiopia south to
the Cape. Serious damage to citrus nursery stock, particularly new growth, may
occur. Nymphs cause pitting of the leaves by feeding on the underside of the
foliage. Pitted leaves do not regain their Shape after the insect leaves. In
Ethiopia, serious damage to lemon was reported in 1961 and to orange in 1963.

Distribution: East Africa, Ethiopia, South Africa, and Sudan.

Hosts: Citrus and plants of the citrus family.

120° 1407 160" Woo" 160" 140" 120100" 60" SO"

LEST TP Os

Life History and Habits: The insect breeds all during the year; however, it is
more noticeable when plants produce new growth. Adults deposit eggs only on
succulent shoots. Hatching occurs in 5-7 days in the Summer and the small nymphs
Settle on the underside of leaves where they feed. Each individual remains in a
Shallow pit unless disturbed. Because nymphs are stationary on the leaves, they
are often mistaken for scale insects. The nymphal stage lasts on the average 20
days in summer and 30 in winter. There are five nymphal instars. The pocked
appearance of the leaves is the primary indication of the presence of the insects.
Adults fly rapidly and are not easily captured on the foliage. Excrement from
both nymphs and adults resembles tiny white eggs. The ground or vegetation under
a severly infested tree appears as though dusted with powder.

Hemiptera: Psyllidae No. 168 of Series

- 802 -

Description: ADULT - Length 2 mm., wing span 6 mm, Pale green with black eyes
when newly emerged, but darkens with age until the head and limbs are dusty
black; thorax light brown; underside of abdomen yellow, dorsum gray. Wings
clear. The males and females differ in the Shape of the abdomen - the male's
being blunt, female's sharp pointed. EGG - Length 0.5 mm. Smooth pear-shaped
yellow. NYMPH - Length 0.5-2 mm. Oval, flat, yellow with 2 red eyespots near
front margin, a narrow white fringe of wax around outer edge of insect.

WEATHER OF THE WEEK ENDING AUGUST 28, 1967

HIGHLIGHTS: Last week was wet in the Southeast and South, continued cool in
Central areas, and continued hot and dry in the West.

PRECIPITATION: Wet, gray skies blanketed an extensive area from the lower Rio
Grande Valley to southern New England most of the week. More than 14 inches fell
at Burton Lake and more than 18 inches at Helen, Georgia, flooding roads and
fields. The generous rains in the Southeast have brought 7-month (January to
August) totals which exceed the annual normals at many stations. In contrast
with the waterlogged Southeast, some of the forests and rangelands in the North-
west had received no rain in more than 2 months until a few scattered weekend
sprinkles occurred. The light rains and increased humidity have done little to
extinguish or prevent forest and range fires. Lightning has started new fires
and winds have made them more difficult to control. Between the two extremes -
the dry West and the soggy Southeast - lay wide areas that received scattered,
mostly light to moderate but locally heavy amounts, Some as much as 3 to 6 inches.
Amounts averaged generally from less than 1 inch over the western Plains to 1 to
3 inches eastward to the Appalachians where amounts generally were greater. Rains
were Somewhat lighter along the Carolina coast and in northern New England.
Weather continued on page 824.

POTATOES, TOMATOES, PEPPERS

Survey to Determine Wireworm Populations During Fall and Spring of 1966-1967
Season and Damage to Potatoes During Spring, 1967, in Vicinity of Charleston,
South Carolina - SOUTHERN POTATO WIREWORM (Conoderus falli) constitued 85 percent
of larvae found in cultivated soil in 21 fields on 12 farms during October 1966.
The all-species populations in various fields ranged 0.25-6.2 larvae per square
foot in top 6 inches of soil; averaged 3. GULF WIREWORM (C. amplicollis)
comprised 4 percent of larvae found; Glyphonyx sp. 8 percent. The proportion

of species other than C. falli has gradually increased since discontinuation of
use of chlorinated hydrocarbon insecticides for soil insect control because of

C. falli resistance to these materials. No such resistance in C. amplicollis has
een noted. Shipping-point inspection certificates issude by Federal-State
market inspectors to Charleston area potato growers during June 1967 showed that
none of 223 lots of potatoes inspected had wireworm damage in excess of 6 percent
(current U. S. Grade 1 tolerance allowance for "damage" due to all defects).
Damage of 3 to 6 percent occurred in 0.4 percent of lots and damage of 1.5 to 2.9
percent in 11.2 percent of lots. Wireworm damage was very low during 1967 spring
season, occurring chiefly in tubers dug during last week of harvest season which
ended June 24. (A. Day, H. Crosby, W. J. Reid, Jr.).

Preparation of Notes for Cooperative Economic Insect Report

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

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

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

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

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

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

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

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

5. Estimation of extent of injury or damage.

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

7. Status of natural or applied control.

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

Examples of notes including these data are as follows:

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

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

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

to 100 percent infested with 2 to 22 larvae per stalk. Larvae from first
to third instar. (Smith).

WEATHER BUREAU'S 30-DAY OUTLOOK
SEPTEMBER 1967

The Weather Bureau's 30-day outlook for September calls for temperatures to
average below Seasonal normals from the Continental Divide to the Appalachians
except for near to above normal over the northern Plains. Above normal temper-
atures are predicated west of the Continental Divide while near normal values
are in prospect east of the Appalachians where large fluctuations are anticipated.
Precipitation is expected to exceed normal east of the Appalachians, as well as
in the Gulf Coast States, Colorado and New Mexico. Subnormal precipitation is
indicated over the Midwest and the northern Plains as well as over the inter-
mountain region and-south Pacific coast. Rainfall amounts equaling or exceeding
normal are indicated for the Pacific Northwest where unusually dry conditions
have prevailed this summer. In other unspecified areas, 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 SEPTEMBER 4

HIGHLIGHTS: Last week brought a continuation of very warm and dry weather in the
Pacific Northwest and of very cool conditions in central United States. The third
week of heavy rains came to parts of Texas.

PRECIPITATION: Tropical Storm Katrina moved northeastward from Lower California
bringing heavy rains to southwestern deserts--over two inches in Yuma, Arizona-—
late in the week. Rainfall amounts varied widely over the central and southern
Great Plains. Heavy rains caused local flooding in the eastern Colorado foot-
hills. Only light to moderate rains came to west Kansas but local flash floods
followed falls of up to 8 inches in some eastern areas. Most Missouri stations
received less than 0.25 inch; a few reported more than 1 inch while 4.88 inches
fell at West Plains. Spotty heavy showers fell in Alabama, Georgia, and Florida.
More heavy rains came to Texas. Most of the north-central and northeast received
small amounts. Light rains in the Far Northwest were insufficient for noticeable
improvement in crops or for the control of forest and range fires. Areas in
Oregon have received no more than light sprinkles in at least 70 days.

TEMPERATURE: A large HIGH remained almost stationery over the Eastern United
States spreading autumn chill from the Rocky Mountains to the Atlantic Ocean.
Much of the central Mississippi Valley averaged 5° to 9° below normal for the
fourth week. [Illinois has averaged cooler than normal for 11 weeks. Morning
temperatures over the North-central States dropped to the 40's and 50's. When
the cold air reached the Gulf of Mexico on Sunday afternoon temperatures in
Alabama remained mostly in the 60's. Summer heat continued over the Far West
with temperatures 8 to 12° above normal from northern Nevada into Canada.
Spokane, Washington, registered 100° on Wednesday. Early September heat affected
the Los Angeles basin; weekly temperatures were 12° above normal at the Civic
Center while the coastal strip remained cool. (Summary supplied by Environmental
Data Service, ESSA.).

WEATHER OF THE WEEK ENDING SEPTEMBER 11

HIGHLIGHTS: Light showers eased the fire hazard in che Far Northwest; widespread
torrential rains hit the southern Plains and lower Mississippi River Valley.

PRECIPITATION: Scattered light rains fell in the Far Northwest early in the week
followed by moderate rains and strong winds along the coast over the weekend. As
the fire hazard diminished, forests were reopened to the public. At some places
in Oregon this was the first measurable rain in 10 to 12 weeks. All of the gulf
coast except southern Florida received moderate to heavy rains. Heavy rains fell
over the Southern Great Plains early in the week, over the lower Mississippi
River Valley at midweek and along the Atlantic coast over the weekend. The down-
pours brought 4 to 8-inch totals along the Oklahoma-Texas border area, over 4
inches in central Arkansas, 6 to 7 inches along the Alabama coast and nearly 14
inches at Pensacola, Florida. Mostly light but occasionally moderate showers fell
over most other parts of the Nation. Much of the Northeast received generous
rains. Hurricane Doria dumped 4.5 inches at Cape Hatteras but less inland.

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

The Weather Bureau's 30-day outlook for mid-September to mid-October calls for
temperatures to average above Seasonal normals over the northern third of the
Nation and also in the far Southwest. Below normal temperatures are indicated
over the southern third of the country east of the Continental Divide. In the
intermediate zone between the above and below normal areas, near normal tempera-
tures are anticipated. Precipitation is expected to exceed normal over the South
while subnormal precipitation is indicated over the Northeast and also the inter-
mountain region. In all other areas not specified, precipitation is expected to
be about normal.

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

published twice a month by the Weather Bureau. You can subscribe through the
Superintendent of Documents, Washington. D. C. 20250. Price $5.00 a year.

PRECIPITATION: Snow fell in the higher Rocky Mountains on Tuesday--10 inches at
Jones Pass, Colorado. Thunderstorms brought generous rains along a slow-moving
cold front that extended from Wisconsin to Texas. Heavier falls included 10+
inches at Dubuque, Iowa, and up to 7 inches over area west of San Antonio, Texas.
About 10 inches of hail fell Saturday near Colorado Springs, Colorado. Wide areas
from the Dakotas to Wisconsin and southward to Texas and Alabama received 1 to 2
inches of rain with much higher totals in spots. Little rain fell west of the
Continental Divide except light showers along the Oregon and northern California
coast. Mississippi, Alabama, and parts of Florida received showers--mostly early
in the week. Hurricane Doria brought light weekend showers to coastal areas from
New Jersey to Cape Hatteras. Little or no rain fell elsewhere east of the
Mississippi. Much of the Northeast reported the driest week in at least. 3 months.

TEMPERATURE: High pressure areas remained almost Stationary over. the West and
East bringing clear skies and much cooler temperatures, especially over the Great
Basin. Subfreezing temperatures occurred at middle and higher elevations in the
northern and central Rockies, and much of Idaho, Nevada, and northern Utah.
General freezes also occurred in the Appalachians from northern Pennsylvania to
West Virginia and scattered freezes hit low spots in the same general area. Much
of the West averaged cooler than normal for the first time since July. In con-
trast, Illinois and nearby States experienced the first warmer than normal week
Since mid-June. The HIGH over the West brought Canadian air into the Basin but
warmed the immediate Pacific coastal areas. The HIGH over the East warmed the
upper Great Lakes region. Cloudy, stormy weather lay between the HIGHS. (Summary

WEATHER OF THE WEEK ENDING SEPTEMBER 25

HIGHLIGHTS: Hurricane Beulah caused widespread flooding in south Texas. Generous
showers fell from the Texas Panhandle to New England. Warm dry weather returned
to the West while the East continued cool.

PRECIPITATION: During her short life, Hurricane Beulah dumped 20-25 inches of
rain over some areas in south Texas and set off several dozen tornadoes. Total
damages to property and crops from wind, rain, and flooding are expected to
approach $1 billion. A cold front, advancing southeastward, caused soaking rains
over the central Plains, the lower Great Lakes region, the Ohio River Valley, and
much of the Northeast. Totals ranged generally 1-2 inches from parts of Texas
High Plains to northern Maine, with spots in the Plains receiving 3-6 inches.
Rain over parts of Nevada, Utah, and northern Arizona caused local flooding.

Most other areas in the West remained dry or received only light sprinkles.
Precipitation was light over the northern Great Plains, and most areas in Alabama,
Georgia, South Carolina, and northern Florida received no rain.

TEMPERATURE: Warm weather returned to the Great Basin and Rocky Mountains. By
Thursday afternoon, temperatures in the 80's were common over the northern Rockies
and the 90's were widespread over inland portions of Washington and Oregon. Cold
Canadian air pushed into the northern Great Plains and advanced toward the gulf
and Appalachians. Patches of frost occurred Friday morning in northern Minnesota
and temperatures in the 50's were common as far south as the Boston Mountains in
Arkansas and the Ohio River Valley. Weekly temperature departures ranged from

+9° over northeastern Oregon and north-central Idaho to -3° over spots in the
central Plains and the southern Appalachians. (Summary supplied by Environmental
Data Service, ESSA.).

CEIR 17(33):756,763 - WESTERN CORN ROOTWORM (Diabrotica virgifera) - MINNESOTA -
Only Chisago and Isanti are new county records. Anoka County reported in 1966.

A Name Change in Bruchidae (Coleoptera)

The valid name for the tamarind seed beetle, or ground-nut bruchid, has been
changed from Caryedon gonagra (Fabricius) to Caryedon serratus (Olivier) according
to Dr. J. DeCelle of Belgium, who made a study of the type specimens (Rev. Zool.
Bot. Afr. 74:169-173, 1966).

This bruchid is often intercepted in Plant Quarantine seed inspections and is
known to breed principally in tamarind seeds (Tamarindus indica L.) in Mexico,
Barbados, Curacao, Dutch Guiana, Hispaniola, Jamaica, and Dominica in the

Western Hemisphere and in tropical Asia and Africa and in Hawaii. It is a serious
pest of stored peanuts, or ground-nuts (Arachis hypogaea L.) in Africa but has

not been found in peanut storage in the United States. The species has also

been found to attack the seeds of several noneconomic Old World legumes.

WEATHER OF THE WEEK ENDING OCTOBER 2

HIGHLIGHTS: Rains, widespread over most of Nation, were heaviest over the East
and along the Northern Pacific Coast. Record cold spread over the Deep South
but the West continued warm.

PRECIPITATION: Rains fell over most of eastern half of the Nation, spreading

from the southern High Plains, eastward to the Atlantic Coast by Friday. Weekly
totals exceeded 0.50 inch over most areas with scattered stations, mostly west of
the Appalachians, receiving from 1 inch to more than 5 inches. Snow flurries fell
in Michigan, Ohio, and in central and southern Appalachians. The weekend

brought heavy rains along the Washington and Oregon coast with light amounts in-
land as far as the Dakotas, Colorado, and Utah. Precipitation was light over the
Great Basin, the northern Great Plains, and most of the Southwest.

TEMPERATURE: Western areas remained relatively warm most of week--exceptionally
warm at mid-week when many Oregon stations registered maximums in upper 80's and
90's. Weekend maximums in the Northwest dropped to 50's and 60's as Pacific air
moved in. A cold from dropped temperatures sharply over the Central and East.
Springfield, Illinois, registered 82° Tuesday afternoon but by midnight the temper-
ature had fallen to 52°. Low temperatures fell to the 20's over the northern
Plains and by Friday, subfreezing temperatures were common as far south as
Tennessee, a month earlier than normal in some places. On Saturday the temperature
at New Orleans dropped to 42° -- 12° colder than any previous September temperature
in 94 years of record. Alabama and Mississippi registered record-breaking low
temperatures for the month of September. A large area from Louisiana to western
Ohio averaged 9° to 12° colder than normal for the week and a much larger area
experienced the coldest weather in 5 months. (Summary Supplied by Enviornmental

INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES

A BLACK FLY (Simulium damnosum Theobald)

Economic Importance: The principal vector of human onchocerciasis, in West
Africa is S. damnosum. The disease commonly causes blindness in humans. [In this
region alone, not including Nigeria and Cameroon, about 2 million people suffer
from the disease or about one-tenth of the population, and of this number 150,000
are blind. Excessive Skin irritation caused by the microfilariae often precedes
failing sight. Onchocerciasis, caused by a filarial worm, has an extensive dis-
tribution in tropical Africa as well as Mexico, Central and South America.
Simulium ochraceum Wlk. and S. metallicum Bellardi are the chief vectors in
Central America. Simulium neavei Roubaud is another important carrier of the
disease in Africa. The microfilariae in the skin of man are picked up by the
vector in which they develop to the third stage infective larvae. The adult
worms which give rise to the microfilariae often occur in nodules which may be
very conspicuous when they occur on the head of an infected person. As typical
of the family, the female only of S. damnosum sucks blood. The bite is painful
and intense itching may follow. a

Distribution: Angola, Burundi, Cameroon, Congo (Brazzaville), Dahomey, Ethiopia,
Gambia, Ghana, Guinea, Ivory Coast, Kenya, Liberia, Malawi, Mozambique, Nigeria,
Portuguese Guinea, Republic of South Africa, Rwanda, Sierra Leone, Southwest
Africa, Sudan Republic, Tanzania, Togo, Uganda, and Upper Volta.

Hosts: Mainly man over most of its range but dogs, donkeys, goats, sheep, and
birds also have been reported as hosts.

160" 140" 120" 00" 60"

General Distribution of Simulium damnosum Theobald

Diptera: Simuliidae No. 169 of Series

= 918 —

Life History and Habits: Females deposit eggs in masses of about 250 on damp
parts of Stones, lLleaveS, dead wood,and stems protruding from the water. Under
West African conditions the eggs hatch in about 36 hours. Larvae may be found

in fast moving, turbulent water of streams and rivers where they attach to stones
and other objects; whereas in some areas of Africa larvae are found in quiet
waters. The larval stage lasts 10-13 days and the pupal stage 4-5 days in West
Africa. Pupation takes place in a loosely woven cocoon. Continuous breeding
throughout the year has been observed in the Volta River but in other areas

where the rivers dry up, the flies probably survive as adults. Because of tax-
onomic variances, the habit of the species to breed in swiftly moving water or in
quiet backwaters, and its tendency to bite man at low altitudes and not at high
altitudes and vice versa, it is suspected that a complex of species may be
involved. Dunbar's (1966) recent cytogenetic work in Uganda supports the idea of
a complex of species.

Description: ADULT - Female length 2-2.5 mm., wing length 2-3 mm. Dark with
dark legs, mesonotum shining. Swollen anterior tarsi are distinctive of the
species. Head black with gray dusting and pale hairs; inner side of mandibles
with about 25 teeth, legs black with silvery scales. Wings, yellowish basally
and halteres yellow. Abdomen shining black on apical half, basal fringe short
and silvery. Male wing length 2-2.5 mm. Mesonotum distinctive - gray areas
extend back and black areas reduced to medium broad stripe or triangle and a pair
of lateral oval patches. Anterior tibiae of legs with shining, silvery scales,
anterior tarsi greatly enlarged as in female. Abdomen black with silvery side
patches. LARVA - With thick coat of short, dark, bluntly pointed spines. Feeding
brushes number about 20.

WEATHER OF THE WEEK ENDING OCTOBER 9, 1967

HIGHLIGHTS: Little rain in East and South except heavy downpours in south Florida.
Flooding rains east Kansas. Weekend hard freeze Northeast Interior. Severe storm
Pacific Northwest early in week.

PRECIPITATION: A vigorous storm dumped heavy rains along the northern Pacific
coast early in the week. Snow fell in the Cascades, Sierras, and Olympic Moun-
tains and light rains extended eastward to Montana and the Dakotas. Showers and
scattered thunderstorms occurred at midweek along a front that extended from the
Northeast to the central Rockies. Daily totals ranged from 2 to 3 inches or more
at some locations in the central Great Plains. During the weekend a frontal
system moved from the Rockies across the Great Plains and Midwest. Widespread
rainfall along the front was particularly heavy in eastern Kansas where amounts
ranging up to 5 inches or more in a few hours caused local flooding. Almost
daily showers occurred in the southern third of Florida and weekly totals ranged
up to more than 7 inches.

INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES

A MOSQUITO (Culex tritaeniorhynchus Giles)

Economic Importance: This Species is considered to be the most important vector
of Japanese B encephalitis in the Oriental region. As many as 6,000 cases with
nearly 4,000 deaths occurred in the summer of 1924 in Tokyo. Death rates in
epidemics have ranged from 40 to 70 percent among the Japanese. The disease, a
virus which attacks the central nervous system, is Somewhat similar to western
(WE) and eastern (EE) encephalitis in the United States. A related species of
mosquito, Culex tarsalis Coq., is a principal vector of WE in the U. S. Outbreaks
of Japanese B encephalitis are sporadic in humans. Culex tritaeniorhynchus pre-
fers to feed on cattle and pigs. OccaSionally, the Species feeds on birds.

Distribution: Bonin Islands, Burma, Central African Republic, Ceylon, China
(Manchuria), Dahomey, Egypt, Gambia, Ghana, Guam, India, Indonesia, Iran, Iraq,
Israel, Japan, Kenya, Korea, Lebanon, Malagasy Republic, Malaysia, Maldive
Islands, Mozambique, Nigeria, Pakistan, Philippines, Ryukyu Islands (including
Okinawa), Saudia Arabia, Senegal, Syria, Taiwan, Tanzania, Thailand, Togo, Turkey,
Viet-Nam, U.S.S.R. (Armenia, Azerbaidzhan, Georgia, and Turkmen).

Scale Larval Siphon and
Terminal Segments

Adult Female

\ ry, /
\ Head of Male Comb

Diptera: Culicidae No. 170 of Series

= 52) =

Hosts: Cattle, pigs, birds,and man.

Life History and Habits: The biology in Japan is as follows: Overwintering
females appear in late March or early April. Under laboratory conditions, a
female deposits up to 4 egg masses, each of which contains about 50-200 eggs.
Hatching occurs in 2 days and pupation in 10 days. Adults appear in 2 days.
Although most females enter hibernation in September, males continue to swarm
until the beginning of November. Mating was observed in the swarms. Larvae have
been collected under various situations in other parts of the Orient. They fre-
quent hyacinth ponds, streams, swamps, temporary and semipermanent ground water
habitats. Reports of their being in tidal marshes of low salinity and occasion-
ally in tins or drums sunk in the ground have been made.

Description: ADULT - Female - Length 5 mm. or less. Generally may be identi-
fied by itS small size, brown scaling on the scutum and accessory pale scaling
on the lower surface of the proboscis. The species is difficult to distinguish
from others in the vishnui subgroup but the long filamentous teeth of the bucco-
pharyngeal armature are diagnostic. Male - Palpus longer than proboscis; two
bands on long segment and 1 each at bases of last two segments. Fore and mid
leg with unequal tarsal claws; the larger with a branch at about the middle but
smaller with one close to its base. LARVA - Fourth stage - Length about 5 mm.
not including siphon. Characterized by arrangement of bristles on thorax (hairs
1, 2, 3, 5, 6-P single pectinate, 4, 8-P bifid, pectinate, 7-P trifid, pectinate
14-P single, simple), shape of comb scales (which are fan shaped), and by ana-
tomical characters of the siphon. The long narrow siphon usually with 5 pairs
of 3 or 4 forked subventral bristles and one pair of 2 or 3 forked lateral
bristles.

WEATHER OF THE WEEK ENDING OCTOBER 23

HIGHLIGHTS: Indian summer prevailed over most of the Nation. Rain fell only in
the Far Northwest and over the eastern half of the Country.

PRECIPITATION: Light rain fell early and late in the week in the Far Northwest.
Totals ranged from 1 to 2 inches along the coast, with 0.5-1 inch in the interior
valleys and light sprinkles farther inland to the Continental Divide. An
extensive area from California to the Great Plains received no rain. A slow-
moving cold front produced heavy rains over most of the eastern half of the Nation
early in the week. Totals exceeded an inch from the middle and lower Mississippi
River Valley to the Appalachians, and 3 inches in a few areas. One spot in
Arkansas received almost 8 inches. Most of the Florida Peninsula received only
light sprinkles.

TEMPERATURE: Most Americans experienced typical Indian summer weather with clear
skies, warm, hazy days, and cool nights. Idaho averaged somewhat cooler than

last week but still slightly above normal. Above-normal temperatures were the
rule west of the Continental Divide, on the western edge of the northern Great
Plains, and in New York and New England. Above-normal temperatures also prevailed
over the rest of the Nation until a cold front advanced southward bringing
subfreezing temperatures as far south as the northern edges of the Gulf States
(Jackson, Mississippi, registered 32° Thursday morning). A few spots in the
Piedmont averaged 5 to 7 below normal. (Summary supplied by Environmental

Data Service, ESSA).

CITRUS

Quarterly Citrus Insect and Mite Outlook in Florida - October through December -

is outlook is based on e assumption at weather beyon e period o e
current U.S. Weather Bureau's 30-day Outlook will be normal. Therefore the

- 959 -

forecasts 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) will continue to increase in October,
hold at high level through November, then gradually diminish in December. Numbers
will be above normal. Between 50 and 60 percent of groves will develop important
infestations this period. TEXAS CITRUS MITE (Eutetranychus banksi) will increase
in November, but expected to be below normal abundance and at moderate level.
About 10 percent of groves will develop important infestations. CITRUS RED MITE
(Panonychus citri) will gradually increase in mid-October through December.
Infestations expected to be fewer and lighter than average for period. Moderate
to heavy infestations will occur in about 15 percent of groves; will be most
destructive to young trees in dry locations. GLOVER SCALE (Lepidosaphes gloverii),
PURPLE SCALE (L. beckii), CHAFF SCALE (Parlatoria pergandii), and YELLOW SCALE
(Aonidiella citrina) will gradually increase but none expected to exceed normal
levels or enter high range. An ARMORED SCALE (Unaspis citri) will continue to
increase and produce fall brood of crawlers. Crawlers carried by picking crews

on clothing and equipment are likely to start new infestations. (W. A. Simanton).

economic (norm 37 percent). Infested fruit in 80 percent of groves (norm 72
percent); 63 percent economic (norm 49 percent). Population continued to increase;

now at highest October level in 16 years of record. Further increase expected

and population will continue high with many heavy infestations in all areas. All
districts high. TEXAS CITRUS MITE (Eutetranychus banksi) infested 13 percent of
groves (norm 20 percent); 3 percent economic (norm 5 percent). Population below
normal and very low. Slight increase underway not expected to develop important
infestations before mid-November. All districts low. CITRUS RED MITE (Panonychus
citri) infested 16 percent of groves (norm 26 percent); 4 percent economic (norm
5 percent}. At very low level. Population will remain low; little increase
expected until late November. All districts low. BLACK SCALE (Saissetia oleae)
infested 17 percent of groves; 5 percent economic. Population decreased to Lowest
October level in 16 years of record and will remain very low in all districts
until 1968. GLOVER SCALE (Lepidosaphes gloverii) infested 57 percent of groves;

6 percent economic. Population below normal and in low range. Slight increase
expected. Highest district south. PURPLE SCALE (L. beckii) infested 42 percent
of groves; none economic. Population below normal. Tnfestations will remain
light and of little importance in any district. CHAFF SCALE (Parlatoria pergandii)
infested 32 percent of groves; 1 percent economic. Population Will gradually
increase but will continue at low level and below normal. YELLOW SCALE (Aonidiella
citrina) infested 60 percent of groves; 2 percent economic. Population increased
to normal October level. Few infestations will be important despite slight
increase expected. Highest district east. WHITEFLIES are below average; slight
increase expected. (W. A. Simanton (Citrus Expt. Sta., Lake Alfred)).

INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES

SOUTH AFRICAN CITRUS THRIPS (Scirtothrips aurantii Faure)

Economic Importance: The species is a major pest of citrus in Southern Rhodesia
and the Republic of South Africa. Heavy losses to citrus have occurred in South-
ern Rhodesia. Nymphs and adults scar oranges and grapefruit by their feeding. A
condition known as "tear staining," which leaves an unsightly scar, is caused
directly or indirectly by feeding of S. aurantii. Thrips usually attack exposed
foliage and fruit, but in heavy infestations they have been reported to feed on
fruit on the inner branches of the tree. Damage to leaves causes a reduction in
yields when the insect is abundant. Market value of fruit is often lowered and,
in some cases, unsalable except as culls.

Distribution: Egypt, Malawi, Republic of South Africa, Southern Rhodesia, and
Sudan.

Hosts: Citrus, cotton, acacia,and numerous other plants including peach and
castorbean.

General Distribution of Scirtothrips aurantii Faure

Life History and Habits: Under conditions of the Republic of South Africa
biology is aS follows: Sexual reproduction is generally the rule but partheno-
genetic development is thought to occur. Females, which are more abundant in the
field than males, deposit eggs within the tissues of young fruit, stem,and leaves
of young shoots or the rind of large fruits. On the average the egg stage lasts
6 days, larval stage 13.5 days,and pupal stage (including prepupal) 4 days.
Pupation takes place in the ground or possibly among debris. Although breeding
occurs throughout the winter, few thrips are found in orchards because of lack of
Suitable food. The entire life cycle ranges from 18 days in summer to 44 days in
winter.

ThySanoptera: Thripidae No. 171 of Series

- 966 -

Description: ADULT - (Female) - Length 0.7 - 1 mm. Torpedo-shaped; translucent,
pale orange yellow wings rest parallel to each other, over abdomen, giving the
illusion of 2 dark brown longitudinal stripes. Two large compound eyes with 3
ocelli occurring between them. Ocelli each with red pigment in form of a cres-
cent. Antennae 8 segmented. Mouth cone short, blunt at apex. Two pairs of very
narrow wings, the edges of which fringed with long slender hairs. Wings rest
over abdomen when not in use. (Male) - Length 0.55 - 0.7 mm. Similar to female.
Apical half of femora of hind legs with a conspicuous comb of 6 stout spines
arranged in a Single longitudinal series. This comb readily distinguishes it
from North American species,

WEATHER OF THE WEEK ENDING OCTOBER 30

HIGHLIGHTS: Violent storms, heavy snow, and cold temperatures characterized the
weather during the past week.

PRECIPITATION: Severe weather associated with a vigorous cold front struck a
wide area from Michigan to the central gulf coast Tuesday and Wednesday. Tor-
nadoes occurred in seven States--from Missouri to Ohio and in Tennessee, Missis-—-
sippi, and Alabama. Monday morning, October 30, tornadoes killed 2 persons,
injured 200, and caused extensive property damage in the Gulfport area of Missis-—
sippi. A large area from Michigan to Texas received more than an inch of rain
with spots in Oklahoma receiving 4 to 6 inches or more. As the cold front
continued eastward, it produced rainfall totals exceeding 1 inch from the Ohio
River Valley to the Appalachians. The Pacific Northwest received rain on sev-
eral days; it was heaviest early and late in the week. Totals ranged from 1 to
3 inches along the coast to 6 to 9 inches on the western slopes of the Cascades
and generally less than an inch farther inland. The desert Southwest--Arizona
and nearby portions of neighboring States continued rainless. The first major
snow of the season hit the northern Great Plains and the Great Lakes region.
Ironwood, Michigan, received 18 inches with totals ranging downward to 7 inches
in northern Illinois, and to 1 to 3 inches in northern Missouri.

TEMPERATURE: The coldest weather of the season came to the Pacific Northwest
with daily maximums in the 40's and 50's. The Southwest continued warmer than
normal. Brisk southerly winds over the East sent temperatures into the 60's and
70's early in the week. Cold air surges hit mid-America early and late in the
week, dropping temperatures 40° or more. Goodland, Kansas, registered 76° Monday
afternoon and 28° by midnight Tuesday. Extensive cloudiness prevented the
temperatures from falling below the 30's over much of the Plains. Subfreezing
temperatures occurred in the southern Appalachians and much of the Piedmont;
Augusta, Georgia, registered 30° Sunday morning. Maximums in the 70's, however,
occurred from the southwestern deserts to Florida. At the end of the week, a new
surge of cold air and northerly winds swept southward across the Plains. (Summary
supplied by Environmental Data Service, ESSA).

WEATHER OF THE WEEK ENDING NOVEMBER 6

HIGHLIGHTS: Winter temperatures spread over central and eastern United States
and the first snow of the season fell from the Rockies to the Appalachians.

PRECIPITATION: Early in the week, widespread rains soaked a 22-State area from
the upper Great Lakes to Texas and eastward to the Appalachians. Violent winds
and heavy rains battered the lower Mississippi River Valley while tornadoes and
waterspouts pounded areas along the middle gulf coast. One of the worst tornadoes
killed 2 persons, injured 200, and caused extensive property damage in the Gulfport,
Mississippi, area on Monday, October 30. At midweek, heavy snow fell in the
central Rockies and nearby portions of the Plains. By Thursday evening, 26 inches
covered the ground at Berthoud Pass west of Denver. Light snow fell as far east

as Springfield, Missouri, and as far south as the Texas Panhandle. The first
general snow of the season occurred in Montana with light flurries in North Dakota.
Snow in South Dakota ranged from 8 inches in the Black Hills to light flurries in
eastern sections. Weekend snow squalls dumped from 1 to 2 feet of snow in north-
eastern Ohio and western New York and snow mixed with rain fell from Arkansas to
the central Appalachians. Rain fell along the northern Pacific coast during the
first half of the week. Totals ranged from 1 to 4 inches along the coast to

light sprinkles 200 miles inland. The Great BaSin and the southwestern deserts
continued dry.

COOPERATIVE ECONOMIC INSECT REPORT

ESTIMATED LOSSES AND PRODUCTION COSTS ATTRIBUTED TO
INSECTS AND RELATED ARTHROPODS - 1966

Introduction
Prior to last year insect loss estimates were published in the Cooperative

Economic Insect Report as individual reports. An attempt has been made for the
second 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 1966 estimates and their
respective States are listed below.

W. P. Boyer Arkansas

L. E. Jenkins Colorado

G. Y. Funasaki Hawaii

C. E. White Illinois

R. J. Huber Indiana

J. H. Simpson Kansas

W. C. Harding, Jr. Maryland

R. Flaskerd Minnesota

D. L. Keith Nebraska

S. R. Race New Jersey

Preparation of Notes for Coopérative Economic Insect Report

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

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

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

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

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

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

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

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

5. Estimation of extent of injury or damage.

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

7. %Status of natural or applied control.

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

Examples of notes including these data are as follows:

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

EUROPEAN CORN BORER (Ostrinia nubilalis) - Oviposition and hatch practi-
cally complete in central counties. Fifty egg masses per 100 stalks in
northwest area. In southern counties, all corn 35 inches or taller, 70
to 100 percent infested with 2 to 22 larvae per stalk. Larvae from first
to third instar. (Smith).

WEATHER OF THE WEEK ENDING NOVEMBER 13

HIGHLIGHTS: Warm weather prevailed over the Far West, in the northern and central
Great Plains while cool weather persisted over the South and East until the
weekend. Rains fell in the Far Northwest and from Texas to the Great Lakes and
New England.

PRECIPITATION: There were two main precipitation areas. The Far Northwest
received their rains mostly late in the week. Three to five inches fell along
the Washington coast with lighter rains inland as far as western Montana. Snow
fell in the mountains. The other precipitation area extended from Texas to the
Great Lakes and New England. Rains were heaviest in central Texas where Taylor
received more than 5 inches. These "cold front" rains occurred late in the

week over the northern Plains and over the weekend along the southern edge of the
rainy belt. A few snow flurries were noted from northern Kentucky to Pennsylvania
early in the week and thunder showers occurred in Pennsylvania on Sunday. Wide
‘areas from California and Arizona to South Dakota and southern Minnesota received
no precipitation during the week. Another rainless area extended from Southern
Louisiana to southern New Jersey and southeastward to central Florida.

TEMPERATURE: Freezing temperatures were widespread early in the week. On Tuesday
morning, freezing weather occurred over. inland portions of Washington and Oregon,
the mountains in California, and eastward across the Southern States to northern
Florida where Tallahassee registered 30°. Many areas from the northern and
central Rockies to the Great Lakes registered temperatures from 10° to 20°. In
spite of the cold beginning, the West warmed rapidly and maximums in the 50's,
60's, and 70's were common by the weekend. Temperatures over the Great Basin
averaged up to 10° above normal. In the East, the cool weather presisted until
the week end. Daily minimums in the 20's were common in South Carolina until the
8th and Georgia reported one of the most persistent early season cold spells on
record. The cold beginning in the East was followed by a Sharp warming trend over
the weekend. Washington, D. C., registered 76 on Sunday. Notwithstanding

the mild weekend, most of the area from Texas to Michigan and eastward to the
Atlantic Ocean averaged cooler than normal. Coastal areas from northern Florida
to New England averaged 6° to 9° below normal. (Summary supplied by Environmental

WEATHER BUREAU'S 30-DAY OUTLOOK

MID-NOVEMBER TO MID-DECEMBER

The Weather Bureau's 30-day outlook for mid-November to mid-December calls for
temperatures to average below seasonal normals over the eastern third of the
Nation with greatest departures in the Northeast. Above normal temperatures are
predicted for the western half of the country. In the intermediate unspecified
area, near normal temperatures with large fluctuations are indicated. Precipita-
tion is expected to be subnormal over most of the country lying east of the
Continental Divide, except for near to above normal amounts frequently in the
form of snow, from the Great Lakes eastward to New England. Above normal amounts
are anticipated over the Pacific Coast States and most of the Great Basin. [In
unspecified areas, 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 NOVEMBER 20

HIGHLIGHTS: Mild weather continued over the West while the coldest weather of
the season visited the East.

PRECIPITATION: Early in the week, a storm off the Pacific coast produced rains
from WaShington to northern California. Eureka, California, received 1.73 inches
in 6 hours. On Tuesday, a cold front followed by other cold fronts late in the
week, brought widespread heavy snow from the northern Prairies to New England.
This included 10 inches at Danvers, Massachusetts, and 17 inches at Boonville,
New York. Four inches fell in the mountains of West Virginia. Some areas south
of the snow belt received mixture of snow, sleet, and freezing rain. A large
deep LOW off the California coast brought 2 to 5 inches of rain over southern
California Sunday with totals in the Los Angeles vicinity ranging up to more
than 9 inches, causing mud slides and local flooding. Light snow fell in the
northern Rockies and a few showers fell along the southern portion of Florida's
east coast, but wide areas from Utah and Arizona to the Carolinas and Florida,
and from the Dakotas to Mexico and the gulf coast received no precipitation.
Some of these areas have been dry for several weeks.

TEMPERATURE: Unseasonably warm weather continued through most of the week west

of the Mississippi River. Phoenix, Arizona, registered 90° Monday afternoon,
November 13; maximums in the central Rockies reached the 60's and 70's on several
days. A large area from Nevada to southern Wyoming and northern Colorado averaged
10° or more warmer than normal. It was a different story east of the Mississippi
River where a series of cold fronts accompanied by gusty winds brought winter
chill from the Great Lakes to the Deep South. Some areas were 10° to 12° colder
than the previous week. Much of the area from Michigan to New England and
southward to eastern Kentucky and Virginia averaged 6° or more colder than normal.
Freezing temperatures occurred in northern Florida on Thursday and Sunday.

WEATHER OF THE WEEK ENDING NOVEMBER 27

HIGHLIGHTS: West cooled and East warmed during week. Heavy rains caused local
floods and mud slides in California.

PRECIPITATION: Far Northwest received no rain or only light sprinkles during
past week. Wide areas from the Great Plains to New Mexico, Texas, and Louisiana
were also rainless or nearly so. The Florida Peninsula was also dry. Ten-inch
rains in the San Bernardino and San Gabriel Mountians, mostly on Tuesday, caused
local flooding and damaging mud slides. Heavy thundershowers occurred elsewhere
over much of the southern third of California while less intense showers visited
nearby portions of Nevada and Arizona and northeastward to the central Rockies.
Snow fell in the northern Rockies in the latter part of the week. General rains
occurred in the East from the 22d to 25th. Amounts exceeded an inch from north-
ern Mississippi to West Virginia and North Carolina and ranged up to over 4 inches
in northern Georgia. Much of New England received more than 1 inch of precipita—
tion; Eastport, Maine, over 4 inches. Heavy thunderstorms with damaging winds
and hail occurred from Alabama to South Carolina Friday afternoon and evening.
Hail as large as baseballs battered Phenix City, Alabama; tornadoes occurred at
Huntsville, Alabama, and at Horrell Hill, South Carolina. Arctic air brought
heavy snow to the lee of the Great Lakes from Michigan to New England.

TEMPERATURE: Temperatures over much of the West averaged above normal early in
the week but dropped to near or below normal as the week progressed. Averages
were below seasonal from Nevada to the Black Hills but slightly above normal
elsewhere, except in Arizona which continued warm. In the central United States,
temperatures ranged from seasonally mild in the eastern sections of the Dakotas
to "hot" in Texas - where afternoon maximums reached the 70's and 80's on most
days and averages over much of the State exceeded normals by 10° to 18°. Much

of the East warmed during the week. Averages still below normal over much of the
Northeast in spite of very mild weekend but rose to above seasonal over the
Southeast. At the end of the period, a new surge of arctic air was bringing the
coldest weather of the season to the northern and central Great Plains. (Summary

THE ‘COTTONWOOD LEAF BEETLE AND RELATED SPECIES WITH SIMILAR HABITS

The cottonwood leaf beetle, Chrysomela scripta Fabricius, is quite common on poplars and willows,
and occurs in nearly all but extreme western United States. Three other common species of the
genus Chrysomela, C. crotchi Brown, C. knabi Brown, and C. lineatopunctata Forster, have similar
feeding habits and distribution. AdultS and larvae of these four species feed on foliage.

Severe infestations, although uncommon, may impair the health of affected trees. The small
figure beside each drawing below equals actual size.

ADULTS - The elytra of all four species are dull yellow to dull orange, and all but one have
black markings in addition. The pattern of black markings of scripta and lineatopunctata are
quite similar; the two may be distinguished by the three median black stripes of the former being
quite narrow and elongate, and those of the latter being broader and not as elongate. Each ely-
tron of knabi has just two median black markings, and that of crotchi is dull orange without

black markings.

C. scripta Cc. lineatopunctata C. knabi C. crotchi

LARVAE - The larvae of all four species are Similar. They are elongate, straight-—bodied and bear
numerous dark spots on a light background. The larva illustrated below is that of the cottonwood
leaf beetle.

INSECTS NOT KNOWN TO OCCUR IN THE CONTINENTAL UNITED STATES

SUGARCANE LEAFHOPPER (Perkinsiella saccharicida Kirkaldy)

Economic Importance; Damage by this delphacid was so extensive shortly after its
introduction into Hawaii in 1900, that sugarcane production was reduced by 70,516
tons during 1903-1904. Feeding by nymphs and adults results in removal of plant
juices and oviposition causes mechanical damage. This is frequently followed by
invasion of the tissue by the red-rot fungus (Glomerella tucumanensis). The
fungus and fermentation of injured tissues cause a reddish discoloration at the
oviposition site; infested parts of the cane may become reddish or closely red-
spotted. Severe attack is shown in the drying of leaves, tapered and contracted
stem joints, damaged crown, and sometimes destruction of the plant. Heavy de-
posits of honeydew cause favorable conditions for growth of molds and fungi on
host plants and retard photosynthesis. P. saccharicida is a vector of Fiji
disease of sugarcane. Symptoms include Stunting, leaf distortion, and formation
of pale green and yellow galls on lower leaf surfaces. Diseased plants do not
recover and where controls are not used, 100 percent loss results. Natural
enemies are numerous and may control leafhopper populations without the aid of
chemicals.

Distribution: Australia (Queensland, New South Wales), China (mainland, southern
part), Comoro Islands, Ecuador, Indonesia (Java), Malagasy Republic, Malaysia,
Mauritius, Republic of South Africa (Natal), Reunion, Taiwan, and the United
States (noncontinental--Hawaii). First found in South America in Ecuador in 1965,

Hosts: Sugarcane, corn, sedges, and grasses, including "Hilo Grass" (Paspalum
conjugatum).

Life History and Habits: Biology in Hawaii is as follows: One to 12 slender
curved whitish eggs may be deposited in a slit cut by the ovipositor in a leaf
midrib, stalk internode, leaf sheath, leaf blade, or Shoot. Females live 30-60
days and may lay up to 300 eggs each. These are deposited at an angle in the
plant tissue with outer ends projecting through the plant epidermis and are
covered with white wax. The preferred oviposition Site is the inner basal por-
tion of the leaf midrib. Incubation varies from 2 to 6 weeks, depending on tem-
perature and humidity. Each of the 5 nymphal instars lasts 4 to 9 days; average

about 7 days. The entire life cycle takes 56 days at 72° and 48 days at 77°.
Nymphs and adults congregate in large numbers at bases of leaves. Adults are

more active at night than during the day as mating, oviposition, and dispersal
take place at night. They seldom fly during the day, but on occasion are so nu-
merous as to form a migratory Swarm.

Description: Adult length 4-4.5 mm.; long-winged forms 6.25 mm. to apex of fore-
wing. Forewings of males and long-winged females narrow and extending beyond
apex of abdomen. Interior half of forewings smoky; a long, dark, smoky stripe
present on middle of wing membrane. Three or four of the membrane veins smoky at
wing apex. Forewings of short-winged females extend only to base of fifth abdom-
inal segment. Both female forms with transparent, colorless forewings with
brownish veins and blackish-brown spots. There are no sShort-winged males. Body
of male mostly pale, brownish-yellow with exception of abdomen which is black
above and beneath with lateral and apical margins pallid. Body of female Similar
in color to that of male, but differs in that abdomen is straw-yellow and irregu-
larly speckled with brown. Ovipositor black.

WEATHER BUREAU'S 30-DAY OUTLOOK DECEMBER 1967

The Weather Bureau's 30-day outlook for December calls for temperatures to aver-
age below season normals over the northern third of the Nation, but above normal
over the southern half. In the intermediate area near normal average temperatures
with large fluctuations are in prospect. Precipitation is expected to exceed
normal west of the Continental Divide and also over the Mississippi and Ohio
Valleys, the Great Lakes, and the Northeast. Amounts somewhat less than normal

are indicated over the central and southern Great Plains and along the south
Atlantic coast. In the northern third of the Nation, where below normal temper-—
atures are predicted, a large proportion of the precipitation will 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 DECEMBER 4

HIGHLIGHTS: Winter storms hit the Northwest, the Northeast, and the middle
Mississippi River Valley while severe local storms struck the Deep South.

PRECIPITATION: The South received light rain early in the week but most of the
severe weather occurred during the latter part. A storm centered over eastern
Arkansas early Thursday caused widespread rain from the southern Plains to the
Middle Atlantic States and recordbreaking November snow to parts of the Northeast.
The Washington, D.C., area received 7 to 12 inches--6.9 inches at Washington
National Airport--on Thursday. New York reported 15 to 30 inches. The 37-inch
fall at Boonville, New York, brought their November total to 84 inches, the
greatest snowfall in any month in 19 years of record. Generous warm rains on
Sunday melted much of the snow from Virginia to New Jersey. Late in the week,

a mammoth storm off the coast of British Columbia brought strong winds and heavy
rains to the Washington, Oregon, and northern California coast with heavy snow
in the mountains. Winds gusted to 100 m.p.h. at Cape Blanco, Oregon, where the
rainfall totaled over 8 inches. Snow reached 30-40 inches in the Cascades in
Washington and 29 inches at Mt. Shasta, California. A weekend storm near the
middle of the Nation produced various kinds of severe weather--tornadoes and

Weather of the week continued on page 1047.

INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES

LINED CLICK BEETLE (Agriotes lineatus (L.))

Economic Importance: Grain is so severely injured by this elaterid in the USSR
and Denmark that replanting is sometimes necessary. Great damage to cereals and
Sugarbeets also occurs in Germany. Forty to 80 percent of plants were killed on
hundreds of acres of sugarbeets, oats, and barley in Sweden in an outbreak in
1918. The wireworm is one of the chief soil pests in nursery plantations in the
British Isles and is very destructive to young grape stock in such plantings in
Italy. In Canada, A. lineatusS was responsible for 60 percent loss to potatoes

in one field on Vancouver ISland in 1949 and was especially damaging to this crop
in Yarmouth area (Nova Scotia) in 1954. This species and the related A. obscurus
(L.) and A. sputator (L.) are regarded as major pests of cultivated crops in
Europe. A. lineatus and A. obscurus are responsible for most of the wireworm
injury in Switzerland. A. lineatus was first found in North America in Canada

in 1947, A. sputator in 1939, and A. obscurus was thought to have been introduced
in 1895-1900 into British Columbia in soil used for packing hop plants. These
species have been intercepted at U.S. ports of entry on several occasions.

Distribution: Canada (British Columbia, Nova Scotia, and Newfoundland) , Central
Asia, Europe (all), Middle East, Near East, and Siberian area of USSR.

Hosts: Wheat, barley, corn, rye and some other grains and grasses, lupine,
potato, carrot, tobacco, pea, hop, peach, grape, turnip, lettuce, sugarbeet,
cabbage, tomato, flax, buckwheat, Jerusalem artichoke, onion, garlic, clover,
rape, Sunflower, oak, pine, spruce and fir.

General Distribution of Agriotes lineatus (L.)

Coleoptera: Elateridae No. 173 of Series

- 1050 -

Life History and Habits: Life history and habits under conditions in France are
as follows: Adults are carnivorous but will attack leaves of cereals. Eggs
hatch between July 10-14. Larvae develop slowly and, being very susceptible to
heat, burrow deep into the soil. Larval development requires almost 4 years. The
larger larvae, which cause the greater amount of damage, go through last molt in
May and descend to a depth of 6-13 inches to pupate. Pupation takes place by end
of June but adults do not leave the pupal cell until following April. In Nova
Scotia, Canada, pupation occurs between July 20-August 15. In Czechoslovakia,
the species is usually found in damp meadows, occasionally in cereal fields.
Larvae attack roots of cereals during early spring and Summer in England. A.
lineatus adults have been observed to be active only at night in that country.

Description: ADULT - Length 8-10 mm. According to Becker (1956), "A. lineatus
is readily distinguished from all other Nearctic species of Agriotes by the very
uneven elytral intervals resulting from the pairing of the striae. There is a
faint indication of this condition in some specimens of mancus and insanus, but
in these cases it is never as distinct as in lineatus. The only species that ap-
proaches lineatus in Size and also has broad mandibles is obscurus, but obscurus
has very coarse punctures on the pronotum, evenly spaced elytral intervals, and
the pronotum is slightly wider than long; whereas lineatus has moderate pronotal
punctures, uneven elytral intervals, and pronotum subquadrate or sligntly longer
than wide."" Becker (1956) also gives more complete information on description
of stages of A. lineatus.

WEATHER OF THE WEEK ENDING DECEMBER 11

HIGHLIGHTS: Stormy weather was the rule over much of the Nation last week. The

West continued cold but mild, cloudy, rainy weather prevailed over the Central
and East.

PRECIPITATION: The Pacific coast storm continued to soak the Far Northwest with
up to 5 inches of rain along the coast, 1 to 3 inches in the interior valleys
west of the Cascades, and heavy snow in the Cascades. Rain fell over the central
and southern Great Plains on Monday and Tuesday and spread over the northern
Plains and eastward to the Appalachians by Thursday. Fog lay over much of the
eastern half of the Nation during the latter half of the week. The weekend
brought more inclement weather to the middle and eastern sections of the country.
Mixtures of snow, sleet, and freezing rain fell in the Lakes region and eastward;
combinations of rain, drizzle, and fog occurred from the central and southern
Plains to the Atlantic coast, and violent weather lashed the Mississippi and
Alabama coast and the Florida Panhandle. Tornadoes occurring in the latter

areas on the 9th, 10th, and 1lth caused considerable damage and, in Florida,

1 death. Reports of other tornadoes are fragmentary. Freezing rain glazed the
roads in western and central New York on Sunday and many schools in the central
counties remained closed on Monday morning. Up to 10 inches of snow fell in
northern Maine on Sunday. Precipitation was generally light from the Rocky
Mountains to the Mississippi River and mostly fair weather with little or no

rain prevailed over Arizona and nearby portions of neighboring States.

- 1060 - SURVEY METHODS

SAMPLING METHOD FOR THE SPOTTED ALFALFA APHID

M. W. Nielson*

History: The spotted alfalfa aphid (Therioaphis maculata (Buckton)) was intro-
duced into the United States in 1954. In a very Short time the pest spread to
nearly every State where alfalfa was grown and caused high losses to the alfalfa
industry. In recent years, the aphid has not been considered an important pest
of alfalfa owing to the use of resistant alfalfa varieties and other means of
control. However, the insect can become a Serious pest in areas where resistant
varieties are not grown or if the insect should develop biotypes which cannot be
controlled by presently grown resistant varieties.

Habits: The aphid prefers to feed on the underside of alfalfa leaves near the
base of the plant. As the population increases, the insect will feed on stems
and eventually work upward as the lower leaves are killed. The aphid will drop
off the leaves when disturbed. Copious amounts of honeydew are produced by the
aphid. When the plants are being killed, thus restricting food supply, the aphid
will produce winged forms which migrate to other more attractive alfalfa fields.
In the Southwest, reproduction is exclusively by parthenogenesis. Sexual forms
are produced in the colder climates where the aphid overwinters in the egg stage.

Seasonal Abundance: In Arizona, three distinct population peaks occur. Sometimes
a fourth peak takes place in January. Usually the main population peaks occur in
April, July, and October. Surveys and population counts should be taken just
before the period when these population peaks are likely to occur.

Sampling: Sampling alfalfa fields with a Sweep net is useful only to determine
the presence of the spotted alfalfa aphid in alfalfa. A simple, practical, and
accurate method of estimating populations in the field is by the leaf-count
system. Aphids are counted on three trifoliolate leaves, each selected at random
from the top, middle, and bottom of plants. These subsamples should be repeated
10 times at random intervals of 20 to 50 walking steps in a diagonal fashion
across the field. Thirty trifoliolate leaves will thus represent the total sample
from one field. Care should be taken during sampling to minimize disturbance and
subsequent loss of aphids dropping from the leaves. To avoid loss, the leaf
petiole is grasped by the thumb and forefinger and slowly turned until the entire
underside of the leaf is clearly visible.

Resistant alfalfa varieties are recommended for control of the spotted alfalfa
aphid. However, aphids will occasionally build up on seedlings of some resistant
varieties. Treatment with recommended insecticides is necessary on all varieties
when the aphid population reaches an average of one per Seedling in seedling
fields or five per trifoliolate leaf in older stands. One seedling is equivalent
to a sample of one trifoliolate leaf of older plants Thus, 30 seedlings should
be included in the sample for alfalfa fields in the seedling stage. An alfalfa
seedling is defined as that stage of the plant between the appearance of the
unifoliate and the first trifoliolate leaves.

INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES

CITRUS FLOWER MOTH (Prays citri Millitre)

Economic Importance: Larvae of this yponomeutid moth are very destructive to
many Species of citrus especially lemons and oranges, They reduce production of
fruit and may prevent development. One type of damage occurs after the fall-
grafting of citrus in Israel. Larvae penetrate the raffia dressing around the
graft-union to feed in the cambium. The union dries and the buds die. A second
type occurs in the Mediterranean area where larvae feed on the floral parts and
web them together. They penetrate the calyx to feed. The resultant damage re-
duces yield. A third type of damage occurs in the Philippines and India where
larval feeding in the fruit rinds causes galls to appear on the fruit surface.
Fruits either drop off the tree before they are mature or if they remain there,
become unmarketable because of unattractive galls. Up to 30 galls may be found
on a heavily infested fruit. Exit holes made by larvae before pupation permit
the entrance of fungi and mealybugs in the fruit.

Distribution: Algeria, Australia (N. S. Wales), Ceylon, Fiji Islands, France

(including Corsica) , Greece, India, Indonesia, Israel, Italy (including Sicily
and Sardinia), Malaysia, Mauritius, Morocco, Pakistan, Philippines, Spain, and
Syria.

Hosts: Many species of citrus.

Lepidoptera: Yponomeutidae No. 174 of Series

- 1062 -

Life History and Habits: Under conditions in the Campania area of southern Italy,
the biology is as follows: Females deposit 60-150 eggs on the corolla or calyx
of flowers of various species of citrus. Hatching occurs in 4-12 days and larvae
eat the flowers and mature fruit. Larvae form galleries in the fruit and gener-
ally remain there until time to pupate, but sometimes they will leave and enter
another fruit to feed before pupating. The length of the larval stage is usually
20-22 days but may be 30 days in the seventh generation. Larvae leave the fruit
and pupate in a loosely woven cocoon inside the calyx. Although pupation usually
lasts 10 days, it may require up to 71 days in the seventh or overwintering gen-
eration. In the Philippines where only 5 generations have been recorded, eggs
are laid on the fruit but seldom on the flowers.

Description: ADULT - Length 2.8 - 3.2 mm. grayish brown with light gray membra-
nous hind wings. Many irregular markings on hind wings. Long, narrow wings with
fringe which is much broader in hind wings. Head, thorax and abdomen light brown.
EGG - Length 0.2 mm. Subelliptical and colorless to light yellow but turns darker
before hatching. Surface with network of irregular hexagons. LARVA - Length when
full grown 4.2 - 5.5 mm. but may extend to 12 mm. in southern Italy. White in
first stage but turning to light green with dark brown head when full grown; semi-
transparent. Color of larva may vary under different conditions. Sparse fine
hairs covering body which is 14 segmented. Dorsal surface of abdominal segments
with thin brownish line extending to lateral margin. PUPA - Length 4.8 - 5.5 mm.
Chocolate brown in color and fastened to host plant by silken threads.

WEATHER OF THE WEEK ENDING DECEMBER 18

HIGHLIGHTS: Violent weather struck much of the Nation during the past week.
Record Snows occurred in the Southwest, tornadoes struck the Deep South, freezing
rain iced the Great Plains, and the coldest temperatures of the season spread over
the northern Rockies.

PRECIPITATION: Heavy snow fell in southern Utah, southwestern and south-central
Colorado, and in the mountains of Arizona and New Mexico. Winds of 30 to 40
m.p.h. piled the snow in drifts up to 9 feet deep closing many roads and isolating
hundreds of persons in Arizona and New Mexico. On Wednesday, a few flakes of
snow fell at La Jolla and San Diego, California. This was the first known
occurrence of snow at La Jolla and only the second occurrence at San Diego.
Freezing rain, mostly after midweek, glazed much of the Great Plains from the
Dakotas to Wisconsin and southward to northern Texas and eastern New Mexico.
Glaze covered portions of New England early and late in the week. Tornadoes
occurred in the Deep South on several days--in Texas on Thursday and in Alabama
and Mississippi over the weekend. One of the worst killed 2 persons, injured 26
others, and damaged or destroyed 156 homes at Huntsville, Alabama, early Monday
morning, December 18. A tornado on the Island of Kauai on Sunday caused $1
million damage to property. This is the 5th tornado to strike in the Hawaiian
Islands in the last 50 years.

TEMPERATURE: The cold trend over the West continued as arctic air spilled
across our northern border bringing the lowest temperatures of the season. By
Wednesday, subzero temperatures occurred over much of the Great Basin, the
Rocky Mountains, and the northern Great Plains. Temperatures averaged below
seasonal from the Pacific Ocean to the Dakotas and southward to Texas. Parts
of the Great Basin and Rocky Mountains averaged 10° to 20° below normal. Tem-
peratures over the eastern half of the Nation averaged above normal in spite
of considerable cooling in the Northeast late in the week. (Summary supplied
by Environmental Data Service, ESSA).

WEATHER BUREAU'S 30-DAY OUTLOOK

MID-DECEMBER 1967 TO MID-JANUARY 1968

The Weather Bureau's 30-day outlook for mid-December to mid-January calls for
temperatures to average below seasonal normals over most of the Nation except for
near to above normal along the gulf coast and in the Southeast. Greatest depar-
tures from normal are anticipated over the central and southern Plateau and the
central and southern Plains. Precipitation is expected to exceed normal from the
southern Plateau eastward to the Atlantic Seaboard, and also along the eastern
slopes of the Continental Divide. Subnormal precipitation is predicted from
Great Lakes eastward to northern New England, and also for the Pacific Northwest.
In unspecified areas near normal amounts are indicated. Where below normal
temperatures are predicted, much of the precipitation is expected to be in the
form of sleet and 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.

INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES

ALMOND SCOLYTID (Scolytus amygdali Guerin)

Economic Importance: Adults and larvae of this beetle cause severe damage to
fruit trees by boring, tunneling, and feeding beneath the bark. A heavy infesta-
tion of larvae can reduce the inner bark to powder. Numerous larval galleries
are formed from each egg gallery made by the adults. The damage may cause death
of the tree. Adults bore into twigs and tunnel into limbs. This injury is
marked by the hardening of sap (gum) at the entrance holes. Diseased and weak-—
ened trees aS well as healthy trees may be seriously damaged. Abandoned dead and
dying trees are a breeding source for future infestations in other areas. Heavy
damage has been recorded in Libya.

Distribution: Afghanistan, Bulgaria, Cyprus, Egypt, France, Greece, India,
Israel, Italy (Sicily and southern mainland) , Lebanon, Libya, Morocco, Spain,
Turkey, USSR (Caucasus and southern Ural Mountain areas), and West Pakistan.
Also recorded from Central Asia.

Hosts: Almond, apricot, plum, peach, cherry, other stone fruits; apple and
quince.

Life History and Habits: The biology under conditions in southern West Pakistan
is as follows: Larvae overwinter in the ends of galleries in tree trunks or
limbs. Pupation takes place in the early spring with adults emerging from the

trees 10 to 15 days later. Mating occurs in 2-3 days in pairing chambers prepared

by the males in the tree bark. After fertilization, the female makes an egg
gallery. One male may fertilize two or more females. A female lays 50-70 eggs
singly in pocket-like depressions along the 50-70 mm. long egg gallery. Hatching
takes place in 1 to 3 days. Larvae then excavate galleries at right angles to
the egg gallery and parallel to each other. Larval galleries average 12-73 mm.
in length, curve irregularly, and gradually increase in size during the 4 weeks
of larval development. Pupation occurs in cells made at the ends of the larval
galleries. There are 4 generations a year with an average adult life span of 7.4
days.

Description: EGG - Diameter 0.5 mm. Extremely small, shiny, spherical, and
creamy. LARVA (full-grown) - Length 6 mm. Oblong and cylindrical, legless,
wrinkled, curved, and creamy white. Head small, brown, and partly concealed in
the enlarged anterior portion of the body. PUPA - Length 4 mm. Soft, white or
creamy white; head hidden beneath prothorax; legs and wing cases pressed close to
the thorax. ADULT - Length 4-4.5 mm. Elongate oval, light yellow and brown,
somewhat shiny with sparse white hairs, Elytra longer than thorax; punctations
ranging from coarse at base to small at apex. Thorax darker than elytra coarsely
punctate with sparse hairs. Antenna, tip of femur, tibia, tarsus, and apical
elytral margin yellowish-brown,.

WEATHER OF THE WEEK ENDING DECEMBER 25, 1967

HIGHLIGHTS: Bitter cold continued over the West until the weekend brought rapid
warming. In contrast the East, unseasonably mild during most of the week, turned
sharply colder Friday. Heavy snow continued in the ‘Southwest and tornadoes
struck the Deep South.

PRECIPITATION: Heavy Snow continued early in the week in the southern Rockies.
By Wednesday 83 inches covered the Flagstaff, Arizona, area. Snow approached
record depth in some sections of southeastern Utah and nearby areas in Colorado
and New Mexico. Three to six inches which fell in the lower elevations in Wash-
ington melted rapidly on Friday causing local flooding. Violent thunderstorms
and numerous tornadoes in the warm, moist gulf air preceeded rapidly falling
temperatures and snow as a strong cold front advanced east of the Mississippi
River. Precipitation amounts exceeded two inches in parts of Illinois, Indiana,
over the Southern Appalachians, and in south-central Louisiana. Tornadoes occurred
in Missouri, Illinois, Indiana, northeastern Texas, Arkansas, Mississippi, and
Alabama. Some of the tornadoes caused extensive damage and a few deaths.

Weather of the week continued on page 1085.

Corn Rootworm Situation in the U.S. - 1967

In the fall of 1967 a questionaire was submitted to entomologists in 30 States in
an attempt to gather information on the corn rootworm problem. Responses were
received from 25 of these States.

The three most destructive corn rootworm species infested an area which includes
almost all of the eastern two-thirds of the United States. The southern corn
rootworm (Diabrotica undecimpunctata howardi) is found in 39 States ranging from
New Hampshire in the Northeast to Florida in the South and Nevada in the West.

The northern corn rootworm (Diabrotica longicornis) is present in 26 States that
range from New Hampshire to Wyoming with the heaviest continuous infestation
extending from Ohio to Nebraska. The western corn rootworm (Diabrotica virgifera)
is found in 14 States centered in the Corn Belt area. The accompanying maps give
the known distribution of these three corn rootworms in the United States.

Control costs and/or crop losses were reported by 16 of the 25 responding States.
An estimated 11,779,700 acres were treated for corn rootworms during 1967. The
estimated corn crop loss was $85,385,010. The average cost per acre to control
corn rootworms ranged from $1.00 to $6.00 and averaged $2.40.

The Major Problem Area

According to the survey, all of the major corn-producing States experienced corn
rootworm problems in 1967. The northern corn rootworm was dominant in Ohio,
Wisconsin, Missouri, Illinois, and Indiana while the western species prevailed

in Iowa, Kansas, and Nebraska. Of these States, only Kansas and Nebraska reported
that rootworm populations had not increased over the past several years. The
continuous planting of corn, increased corn acreages, and chlorinated hydrocarbon
insecticide resistance were the major factors contributing to the 1967 corn: root-
worm problems in these States.

The predictions for 1968 were for a continuing problem with more control efforts
along with population increases of northern and western corn rootworms in Illinois
and western corn rootworm in Missouri. With the exception of Iowa, all the above
States reported corn rootworm adults had affected pollination. Annual rotation

of corn with soybeans or weed-free crops was listed as the chief cultural practice
used. Resistance to recommended insecticides ranged from none in Indiana and Iowa
to some resistance to chlorinated hydrocarbons in Missouri, Ohio, Illinois,
Nebraska, Kansas, and Wisconsin.

Conditions in the South and Southwest

Noticeable corn rootworm problems in the Southern and Southwestern States during
1967 were limited to Alabama, South Carolina, Kentucky, and Tennessee while
Texas, Oklahoma, Mississippi, and Arkansas reported no real importance. They
were only a minor problem in Georgia and North Carolina. The southern species
was dominant in all States except Tennessee where the northern species was most
numerous. Only Texas, South Carolina, and Kentucky reported rootworm increases
over the past Several years. The continuous planting of corn, increased corn
acreages, and Suitable host plants were among the factors contributing to the
1967 problems.

The 1968 outlook in the Southern States ranged from increased importance in Texas
and Kentucky to no problem in Alabama. Unchanged conditions were predicted for
South Carolina, North Carolina, and Mississippi with only minor difficulties
forcasted for Tennessee and Oklahoma.

Rootworm adults were reported as affecting pollination in Kentucky, South Carolina,
Tennessee, and Texas. Crop rotation, early planting, and decreased corn acreages
were cultural practices used to reduce the importance of corn rootworms. Only
South Carolina noted a resistance to recommended insecticides.

Conditions in the East and Michigan

Corn-producing States in the East generally reported that rootworms were of
limited or of no Significance in 1967. The southern corn rootworm was dominant
in Delaware, Maryland, and Pennsylvania while the northern species prevailed in
Michigan. Only Michigan reported that rootworm populations had not\increased
over the past few years. Continuous corn planting and late planting were factors
contributing to the 1967 corn rootworm problems of the above States.

Predictions for 1968 were for conditions to remain the same as in 1967 in all the

States except Delaware where the northern Species may become important. Crop rota-
tion was the cultural practice used in Maryland, Pennsylvania, and Michigan to pre-
vent corn rootworm problems. Rootworm adults affected pollination only in Michigan.

Conditions in the West

The important corn-producing States in the West experienced a limited problem in
1967. The western corn rootworm was the dominant species in Colorado and Wyoming.
Both States reported that populations had increased over the past several years
and attributed continuous planting of corn as the major factor for this problem.

The general outlook for 1968 predicted abundant populations in nonrotated fields
in eastern Colorado and considerable damage in GoShen and Platte Counties of
Wyoming. Corn rootworm adults affected pollination to some extent in both States.
The main cultural practice employed to prevent rootworm problems was crop rotation.
Rootworm resistance to recommended insecticides was noted only in Colorado.

Outlook

The general 1968 outlook for all the reporting States was for a continuing problem
in the major corn-producing States, little increased importance in the Southern
States, very minor importance in the Eastern States, and abundant and/or damaging
populations in the Western States.

INTRODUCTION

The 1967 index is a consolidated index, with common and scientific names appearing in
alphabetical order. Page numbers appear only under the scientific names, except for
general common names such as aphids, bees, leafhoppers, mites, etc.

The explanations that follow will aid in the use of the 1967 index.

2.

Page numbers underlined represent references to "Summary of Insect Conditions in

the United States - 1966."

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

Complete cross indexing of page references of insects with common names is not
used. The scientific names should be used to locate all page references, except
for those insects or groups of insects where scientific names were not reported.
In such instances, page references will be found under common names.

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