INSECT PEST SURVEY


Vol. 17 June 1, 1937 No. 4



THE MORE IMPORTANT R CORDS FOR MAY

During the last week in the month grasshopper hatching was generally
under way on the Great Plains and in the upper Mississippi Valley. In the
East Central States hatching had begum but was decidedly retarded by cool
wet weather. In general, these insects are numerous enough to cause con-
siderable trouble this year.

Mormon crickets in many places are migrating from the egg beds and
are reported as decidedly more abundant than last year over the greater
part of the infested territory from South Dakota, to Idaho and Utah.

Damage by wireworms is recorded over a wide territory from Connect-
icut to the Carolinas and westward to California. The outbreaks, however,
are scattered.

The curculio NTaupactus leucoloma Boh., which was discovered for the
first time in the United States in Okaloosa County, Fla.,last year, is
again active. The insect is att.ckiLr:.- a wide variety of crops, including
velvetbeans, peanuts, corn, and cotton. In some fields three-fourths of
the corn plants have been destroyed.

May beetles began to emerge during the latter half of the month.
Heavy flights were recorded in the South Atlantic States and in Kentucky,
with instances of complete defoliation. The white grubs were reported as
doing considerable damage to pastures in parts of Minnesota.

Cutworms are generally abundant and destructive. Considerable damage
in the East Central States was caused by climbing cutworms.

A heavy armyworm outbreak is under way in the Mississippi Valley.
The earliest reports were received from Missiosippi and Akansas, and later
in the month reports of damage were received from as far north as Illinois,

and westward through Oklahoma to Texas. Over 20,000 acres of oats were lost
in one county in southeastern Arkansas. Reports of damage by this insect
have also been received from eastern Virginia and the Eastern Shore of
Maryland.

General and heavy infestations of the corn ear worm are reported from
Florida and Georgia, and around the Gulf to Louisiana. In Los Angeles County,
Calif., rather heavy infestations have been reported on sweet corn.

The chinch bug has been slow in leaving winter quarters in the East
Central States. About the middle o" the month localized but somewhat severe
infestations were reported from South Carolina and Mississippi.

The pea aphid is decidedly abundant and destructive over a widearea
attacking both alfalfa and peas. Reports of heavy infestation of alfalfa
have been received from Virginia, Kansas, Utah, and the Pacific Northwest,
while damaging populations on peas were recorded from southeastern Virginia,
Delaware, and Maryland and parts of Ohio and Utah. The insect is thus far
comparatively scarce in Wisconsin.

The clover leaf weevil has been unusually'abundant in the East Central
States and westward to eastern Kansas and Iowa. ,

During the month the vetch bruchid was reported from four additional
counties in North Carolina.

Spring-brood emergence of the codling moth was about complete the
third week in May in Georgia. In west-central Virginia the first moths
were taken by the middle of the month, first moths appeared in Delaware on
May 6, in Pennsylvania on May 19, and up to May 24no moths had yet appeared
in the upper part of New York State. In the Mississippi Valley the peak
of emergence was reached during the last week in the month in Missouri and
southern Illinois. The first adults were observed in southern Ohio on
May 17. Over a large part of the area the infestations are from moderate
to high.

Although in general the eastern tent caterpillar appears to be less
abundant than it was last year, populations are heavy throughout New England
and the Middle Atlantic States, in some places being even greater than last
year.

Fruit aphids, in general, are decidedly less troublesome than usual.

The plum curculio infestation in the Georgia fruit belt is said to be
the lightest in 18 years. No heavy infestations by this insect have yet been
reported from any of the States.








-155-


The seed corn maggot was very abundant in the lower Mississippi
Valley, from Kentucky and Missouri westward to 1L'braska and Oklahoma.
Reports have been received of severe damage to peas in Washington State
and to beans in the vicinity of Washington, D. C.

Survival of the Mexican bean beetle in hibernation cages in Colum-
bus, Ohio, was the heaviest for several years. The insect started appearing
early in the month in Virginia, Georgia, and Alabama, and late in the month
was quite prevalent at least as far north as Maryland.

The beet leafhopper populations are rather large both in southern
Idaho and in Utah.

The boll weevil is appearing in larger numbers than at any time
during the last 3 years in parts of South Carolina, whereas in Georgia the
brood seems to be the smallest in many years, as is also the case in the
Delta section of Mississippi and in Louisiana. Emer';:nce in Texas was very
high, having been exceeded only three times in the past 12 years.

There was a heavy emergence of the rink bollworm in the Big Bend of
Texas during the last week in April, indicating higher survival than last
year.

Periodical cicada appeared during the last 2 weeks of the nionth
throughout its known habitat.

A hea.-j outbreak of cankerwormns appeared in northeastern Missouri.
By the end of May they were stripping elms and other trees. Reports of
similar, though less severe,damage were received from New E;-:. ', New York,
Ohio, Indiana, and Oklahoma.

Dog ticks are apparently mr.re abundant than usual throughout the
Middle Atlantic and East Central States.

GENERAL FEEDERS


GRASSHOPPERS (Acrididae)

Illinois. W. P. Flint (May 24): Grasshopper eggs have been hatching in
central Illinois for the past 2 weeks. The hatch has been slow, except
on the sand areas. Probably not more than 2 percent of the eggs have
hatched.

Wisconsin. E, L. Chambers (May): 'A few were just beginning to hatch on the
lighter soils in Green County. Cold, cloudy weather is holding them back.

Iowa. C. J. Drake (May 19): Grasshoppers are hatching throughout most of the
infested areas in the State. County agents in the western part of the
State and in sandy areas along the Mississippi River are reporting very
heavy hatching. Baiting has started on Muscatine Island, but not much
bait will be broadcast before the first week of June.'

Missouri. L. Haseman (May 26): Moderate-to-heavy hatching of grasshoppers
has been reported the last 10 days, particularly on sunny slopes, all the
way from Arkansas to thelIowa line. Some counties are reporting the
hatch as the most threatening they have ever known.

Arkansas. Little Rock Democrat (May 21): The first report of grasshopper
damage was received today from Poinsett County, where 50 acres of cotton
and soybeans have been destroyed.

North Dakota. F. G. Butcher (May 24): Grasshopper hatching just getting under
way in the western and central counties. The predominant species is
Melanoplus mexicanus Sauss., hence early injury is apparent in wheat fields.

South Dakota. H. C. Severin (May 21): Reports of large hatches of grasshoppers
have been sent from a few counties. We do not expect as serious an out-
break as that of last year.

Nebraska. M. H. Swenk (May 20): Grasshoppers, M. differentialis Thos., M.
bivittatus Say, and other species, began hatching in south-central and
northeastern Nebraska during the last week in April, but it was well
toward the middle of May before the hatching became general and heavy. An
exceptionally heavy hatch is now under way in at least one-third of the
counties and damage is being done in fields of alfalfa, clover, and other
crops.

Kansas. H. R. Bryson (May 15): Reports of the occurrence of young hoppers
have been received from Chanute and Augusta, in southeastern Kansas.

J. R. Horton (May 21): A survey of 40 separate square-foot samples
of wheat and alfalfa land on April l4 disclosed 11 grasshopper egg pods.
Eggs viable. Hatching began about May 15. Young hoppers conspicuous
today.






-155-


Oklahoma. C. F. Stiles (May 20): Grasshoppers are being reported in large
numbers throughout the northern and western sections of the State. Osage
ind Comanche Counties report that they are three times as numerous as
they were in 1936. At present they are quite small and a number of
species are involved.

Texas. R. R. Reppert (May.26): Cottle, Dallam, Gray, Hamilton, Hardeman,
Lipscomb, Throckmorton, and Theeler Counties are reporting heavy infesta-
tions of grasshoppers.

Montana. H. B. Mills (MW/ 20): Hoppers are now hatching throughout the State.
They are extremely abundant but infestations are spotted. Some are in
the third instar.

Idaho. J. R. Douglass (May 9): Young grasshoppers were observed in the foot-
hills of the Snake River plains of south-central Idaho.

.Utah. G. F. Knowlton (May 8): Nymphs are beconincr moderately abundant in
some fields in northern Utoh. (May 17): They are damaging young beets
at Provo, Utah County, and are especially abundant in alfalfa west of
Kaysville, Davis County. One winged adult, Trimerotropus vinculata
Scudd., was observed at Farmington, Davis County.

Nevada. G. G. Schweis (l.I[y 25): Grasshoppers have been reported from Lyon
and Washoe Counties in destructive numbers and control camrarigns are
being inaugurated.

California. S. Lockwood (May 10): Grasshoppers in San Luis Obispo County
range from the first nyr.'h.al instar to adults. The outbreak is not as
serious as that of 2 years ago. Grasshoppers are appearing in great num-
bers in Imperial County. (May 25): M. mexicanus is more than ordinarily
abundant in the Imperial Valley. Most of them are adults or are in th_*
fifth instar. Mating has not been observed. Alfalfa, melons, and other
vegetable crops are being considerably damaged.

:;CRI01ON CRICKET (Anabrus simplex Hald.)

South Dakota. H. C. Soverin (May 21): Mormon crickets have been reported as
very abundant in Mellette and Lyman Counties. If these crickets become
seriously harmful in South Dakota this year, it will be for the first
time. Heretofore, the crickets were regarded chiefly as a curiosity.

Montana. H. B. Mills (May 20): Mormon crickets are worse this year than ever
before. They cover considerable territory in a triangular area extending
from Madison and Powder River Counties on the south to Hill and Glacier
Counties on the north.

Wyoming. C. L. Corkins (April 28): Hatching was reported in the Crooked
Creek area in northern Big Horn County on April 5- Dusting operations
were started in this district April 19. On April 27 the crickets were in
the second instar and were severely damaging alfalfa fields. Aoril 27 the
hatch was out over all the lowlands in Sheridan County and covers all of






-156-


the area shown in the fall egg survey. The hatch was also out in Crook
County and covers twice.. as much territory as shown in the all' survey.
Eggs have started to hatch in the lowlands of Converse County, but have
not yet hatched in Washakie,'Teton, and Lincoln Counties, as the beds have
been covered with snow. Dusting operations werestarted in Sheridan and
Crook Counties April 26.

Idaho. C. Wakeland (May 25): In the earliest counties Mormon crickets are
reaching the sixth instar in development, while. in the later areas they
are in the first and second instars. The crickets farthest advanced in
development are migrating freely and invading adjacent cultivated areas.
The population is much heavier and more widely distributed in western
Idaho than in 1936. ,

Utah. C. J. Sorenson (May 20): Infestations in Juab, Millard, and Tooele
Counties are heavier and more widespread than in 1936. Hatching began
late in February in parts of Tooele County and on March 5 in Millard County.

Nevada. G. G. Schweis (May 25): The control campaign against the Mormon
cricket is underway in Elko, Humboldt, Eureka, and Lander Counties.

WIREWORMS (Elateridae)

Connecticut. N. Turner (May 4): About one-half acre of transplanted lettuce
in Bridgeport badly damaged by Melanotus sp. Fifty percent of the plants
killed, 3 to 4 wireworms per plant.

Maryland. E. N. Cory (May 19): Larvae are injuring young tomato plants at
Hagerstown.

South Carolina. F. Sherman (May 24)6 Wireworms are injuring tobacco in eastern
South Carolina, reported by J. G. Watts.

W. M. Lunn and N. Allen (May 22): Slightly more than 16 acres
of tobacco is being grown on the Pee Dee Experiment Station farm, in
Florence County. The plants were transplanted during April and the first
part of May, and it has since been necessary to replace approximately
60 percent of them. Examination of plants in the field shows that from
70 to 80 percent of all plants have been injured by wireworms, approxi-
mately 20 percent of the plants having been destroyed.

Indiana. J. J. Davis (May 27): Wireworms have been reported as destroying
corn at Greensburg and Paoli.

Missouri. L. Haseman (May-26): Scattered reports of wireworm injury have
been received from points throughout the State, the last ones referring
to damage to winter barley.

North Dakota. J. A. Munro (May): Farmers in eastern counties are expressing
concern about the, possibility of serious injury to corn, barley, and
other crops from wireworms. Reports indicate that the wireworm popula-
tion is especially high in fields which were summer-fallowed last year.






-1-7-


Nebraska. M. H. Swenk (May): On M":y 1 a Custer County correspondent r-ported
that hip field, just recently plowed, was badly infested with corn-wire-
worms (Melanotus sp.). A complaint of wireworms damaging planted potatoes
in Antelope County was sent in on :&.y 19.

Oregon. H. P. Lancaster (May 21!): Larvae of Limonius canus L>c. und L.
californicus Mann. wore found feeding on nearly every rea plant examined
in lowland on both sides of a small stream near Athena, Umatilla County,
in northeastern Oregon. About 50 percent of the plants have been killed.

California. M. W. Stone (April 30): Specimens of Aeolus livens Lec. submitted
by C. S. Morley of Kern County, %who reported thay they were a.mag6ing melons
near Bakersfield.

A CURCULIOIID (Amalus haemorrhous Hbst.)

Washirn-ton. W. W. Baker (May 12): Five specimens have been swept from clover,
grass, mustard, Rumex acetosella, and equisetum growing near the labora-
tory at Puyallup. Attempts to find it on heather have so far been unsuc-
cessful.

A CULRCULICOID (luaupactus leucoloma Boh.)

Florida. J. R. Watsorn (My 22): Thi i insect, which was discovered last year
for the first time" in a small section of Okaloosa County and adjacent
parts of Alabama, is again active. The grubs are doing severe damage over
a limited area. In some fields a third of the cotton plants were being
destroyed and three-fourths of the corn. The p)est was also attacking
velvetboans and oeanuts. It seems to be a general feeder. adults and
no pupa were observed the middle of 1May. Identification by L. L. Buchanan.

JAPANESE PE2L (Porillia japonica Hewm.)

Connecticut. W. E. Eritton (11ay 21): Lawn diggings indicate that the Japanese
beetle will doubtless be more abundant this year than ever before in Bran-
ford, Brid--.port, Hartford, :cvi London, New H.v."n, and Ridgefield, all in
the southern part of the State.

OR-71TTAL BEETLE (Anouala orientalis Wtrh.)

Connecticut. W. E. Britton (Ma-- 21): This insect is spreading slowly in the
vicinity of !T.-w Haven, where many untreated lawns have "een injured. We
are now finding it in some other torms and cities.

New York. W. E. BlD.uvelt (May 24): A heavy infestation of -grubs was observed
in a large lawn at Wheatley Hills, Long Island, or Ms Several
square-foot diggings in the worst-infested part yielded an average of
80 grubs -per square foot. Much of the turf had bcon killed out. (,.t.
by H. C. Hallock.







-155-


ASIATIC GARDEN'BEETLE (Autoserica castanea Arrow)

Connecticut. W. E. Britton (May 21): Some injury by the adults to various
flowering plants in New Haven has been observed but seldom are the grubs
found in lawns. Two lots of grubs received this spring indicate that this
beetle may soon become troublesome also as a lawn post.

New York. W. E. Blauvelt (May 24): Considerable injury to lawn turf was
observed at Rye, Westchester County, on May 10. (Det. by H. C. Hallock.)

MAY BEETLES (Phyllophaga spp.)

Vermont. H. L. Bailey (May 25): Up to May 25 only a few scattered adults were
noted at Montpelier, Washington County, central Vermont.

Georgia. T. L. Bissell (May 14): On May 5 we received a report of damage to
pecan trees by May beetles, the first record of injury this year;.

Virginia. G. R. French (May 22): I was struck with the large numbers of one
of the May beetles in Culpoper and Rappahannock Counties this week. I
saw one 20-foot oak tree that was entirely stripped and a neighboring
maple was partly defoliated.

R. A. St. George (May): P. fervida F., P. inversa Horn, P. fraterna
Harr., and P. hirticula Knoch, were collected at Falls Church on May 4
and 5.

Kentucky. W. A. Price (May 22): Hordes of May beetles are feeding on oak and
persimmon trees at Lexington. This is the first real damage they have
done.

Wisconsin. C. L. Fluke (May 20): Flights of the adults have been light, as
temperatures so far have been too low :for extensive ones. The first.
appearance was noticed May 7-

Minnesota. D. J. Pletoch (May 1): W7hite grubs have caused much damage to
pasture in Goodhue County. Upon digging damaged hillside slopes, some
adults were found near the surface. These were P. tristis F., mos't4,
abundant, and P. fusca Froel. At depths of from 6 to 18 inches numerous
larvae were found. Some were Brood A, but apparently most were Brood B.
They averaged about 5 or 6 per square foot. Last fall the entire pasture
sod could be peeled back easily, but self-seeding has brought back most
of it.

North Dakota. J. A. Munro (May): May beetles moderately abundant at Fargo.
Most of the adults are in the top layer of soil but a few have been
observed in flight.

Utah. G. F. Knowlton (Ma 18l): A few adult brown May beetles were collected
at Logan during the past week.

these insects are present over the State in more than average numbers.
Control measures being generally applied.

South Carolina. W. C. Nettles (May 21): Cutworms were damaging cotton and
truck crops near Ridgeland the first part of May.

Florida. F. S. Chamberlin (May 6): Cutworms are causing more damr.ge than
normal to newly set tobacco in Gadsden County. Infestations are most
harmful in the later settings.

Ohio. T. H. Parks (May 24): An outbreak of climbing cutworms on grapes de-
veloped in a large vineyard in Franklin County, central Ohio, the week of
April 25. The cutworms were rapidly devouring the young grape buds. The
adjoining county, Fairfield, was the only other county from which similar
trouble was reported.

Indiana. J. J. Davis (May 27): Cutworms have damaged onions and buds of apple
and peach in northern Indiana.

Kentucky. W. A. Price (May 24): Cutworms are'abundant over the State.

Tennessee. L. 3. Scott (Mlay g): Cutworms are extremely abundant and seri-
ously damaging tobacco, corn, tomatoes, and peppers in Mont r.Lcry County.
(May 25): As many as 10 dead cutworms found near one tobacco plant in a
field near Clarksville which has been treated with poison bait. This
field averaged 3i- dead wcrms per plant. :;LJV growers who failed to use
bait have been forced to reset more than 50 percent of their plants. A
man from the laboratory collected 700 cutworms in a neglected pasture in
90 minutes.

Mississippi. C. Lyle (May 24): Specimens of Lycophotia margaritosa saucia
Hbn. on cotton w.rc- received from Yazoo City on iMay 5 and from Cruger on

according to IN. L. Douglass of Grenada. Speciu.2ns of Agrotis ysilon
Rott. were collected by D. W. G-rimns on cotton on three plantations at
Cary and Blanton, in Sharkey County.

Louisiana. C. 0. 7ddy (May): Cutworms were reported to be very abundant in
all parts of Louisiana.


-159-









Missouri. L. Haseman (May 13): A few moths of the greasy cutworm (A. ypsilon)
were noticed about May 3 to 7 in central Missouri. (May 26): Serious
complaints of cutworms are coming from the. southern third of the State.
In the central part half-grpwn cutworms are abundant and are damaging
young plants. .

Arkansas. D. Isely (May 20):. Injury by ,. margaritosa saucia in Washington,

most of the State, but in certain areas the damage is more serious than
usual.

Kansas. H. R. Bryson (May): Cutworms were seriously injuring ripe strawber-
ries at Manhattan the last of May. The pale western cutworm was reported.
as causing considerabl5le damage to wheat in west-central and' northwestern-
Kansas from April 24 to May 1. Moths of the army cutworm (Chorizagrotis
auxiliaris Grote) were reported as appearing in large numbers in one
locality in west-central Kansas on May 20. On May 27 the variegated cut-
worm was attaining a considerable population in the eastern half of Kansas
and some reports of injury have been received. Larvae are from ohe-half
to two-thirds grown.

J. R. Horton (May 26): At Wichita damage by the variegated butworm
is becoming severe tb wheat and young corn. Larvae are migrating from
cut alfalfa to garden crops and onions are being destroyed. Some larvae
are two-thirds grown.

dant in spots, especially in Rosebud, Stillwater, and Gallatin Counties
about May 1, although little damage is reported.

Idaho. C. Wakeland (May 25): Cutworms ar'e destroying stands of sugar beets in
southwestern Idaho and a few fields are being replanted to other crops, The
long, cool spring has delayed development of the larvae and they have done
an unusual amount of damage. Cutworms are also very abundant in range
areas but injury is not easily apparent.








Utah. C. J. Sorenson (May 20): Cutworms are appearing in Utah County, at
Cedar Valley and Lehi West Hills. A few localities on Levan Ridge, Juab
County, also showing damage.

California. J. Wilcox (May 12): L. margnritosa saucia completely defoliated

southeastern Idaho. Moths were very abundant in Russian-thistle areas last
.autumn and in the same areas countless numbers are now in flight at dusk.

Utah. G. F. Knowlton (May 28): Sugar beet webworm moths are becoming alarm-
ingly abundant in Cache and Davis Counties.

H. E. Dorst (May 25): Enormous numbers of beet webworm moths have been
taken in light traps in northern Utah. Many moths have been observed in
sugar beet fields in Sevier Valley.

Georgia. T. L. Bissell (May 7): Moths are unusually numerous in central
Georgia at Experiment and Milner.
Florida. H. T. Fernald (April): Caterpillars are feeding in enormous numbers
on fields yellow with blossoms of Senocio lobatus along the St. Johns River
west of Mims and probably all along the river.

A CABBAGE BUTTERFLY (Pieris monuste L.)

Florida. H. T. Fernald (May): A flight, under way February 6, seemed to have
been checked by colder weather. It was under way again at Daytona Beach
(going north) on April 10; still going north on April 24 at Daytona Beach;
and I saw a car in Orl-indo on May 1 with many butterflies on the radiator.
It had evidently come in from the East Coast. On May 10 I drove to Indian
River City, then north to Daytona. The migratory flight was over, although
a little north of New Sri;rna they wore quite abundant, fcedirn7 freely on
Bidens sp., and what little movement there was was northward. Practically
none at Daytona.
none at DaytCFAiE FLIES (Tipulidae)

Kentucky. W. A. Price (May 24): Crane flies are very abundant at Lexirngton.

Missouri. L. Haseman (May 26): During the last 10 days of May one of the heav-
iest flights of a large species of crane fly that I have ever seen in the
State has appeared throughout central Missouri. In places the shrubbery,
tree foliage, and grasses are liter-'.lly swarming with those crane flies.










CEREAL AND FORAGE-CROP INSECTS


HEAT AND OTHER SMALL- GRAINS

CHINCH BUG (Blissus leucopterus Say)

Indiana. J. J. Davis (May 27): Chinch bugs are not yet abundant in small
grain, as indicated by a few observations, but the bugs are being collected
in noticeable numbers in sweepings in wild grasses.

Illinois. W. P. Flint (May 24): Chiinch bugs have been very slow in'leaving
winter quarters because of the abnormally cool weather. Flights from
winter quarters are still going on. Bugs are not all concentrated in
small grains, even at this late time. :

South Carolina. W. C. Nettles (May 21): On May 15 serious chinch bug outbreak
was reported in York and Chester Counties.

Mississippi. C. Lyle (May 24): On April 26 a field of young corn was being
destroyed at Magnolia in the southwestern part of Mississippi. Complaints
of chinch bugs are rarely received from that section. A complaint was
received from Meridian on May 15 'and reports of serious local damage to
corn on two plantations near Durant have been received.
I
Kansas. H. R. Bryson (May 22): Chinch bugs are present but not numerous at
Manhattan.

Oklahoma. F. A. Fenton (May 24): One report..on chinch bug damage was received
from Claremore. .

HAIRY CHINCH BUG (Blissus hirtus Montd.)

New York. W. E. Blauvelt (May 24): Adults were observed laying eggs at Locust
Valley on May 1. Infestations in lawns were observed at Port Chester and
Mamaroneck on May 10, at Locust Valley and Wheatley Hills on May 12, and
at St. James on May 14, all in the vicinity of New York City.

APHIDS (Aphiidae)

Virginia. W. J. Schoene (May 24): Alfalfa fields and oat'fields at Blacksburg
are being seriously injured by aphids of an und.etermined.species.

A. M. Woodside (May 22): Aphids are general on grain crops, but no
heavy infestations have been observed, except on barley near Timberville,
in Rockingham County.

ARMYWORM (Cirphis unipuncta Haw.:)

Maryland. C. G. Woodbury (May 31): The country between Cape Charles and
Cheriton is alive with armyworms, attacking wheat and vetch.







-163-


Virginia. H. G-. TWlker and L. D. Anderson (May 25): Outbreaks of army-worms
have occurred in a few fields of oats, barley, and corn near Norfolk,
but in general the infestation has not been as general or as severe as
last year.

Indiana. J. J. Davis (May 27): Moths of the armyworm have been abundant at
lights during the Last week.

Illinois. W. P. Flint (May 24): There has been a moderately heavy flight of
adults. Young worms are now common in heavy grass growth in the southern
third of the State.

Kentucky. W. A. Price (May 26): Specimens of the armyworm were received in
the mail today from Morganfield in Union County, western Kentucky, with
the statement from the county agent that the outbreak was rather widespread.

Assoc. Press, Washington, D. C., Evening Star (May 31): Thousands
of arnwworms infested rye fields near Oakland, Warren County, in the
western. part of the State.

Florida. J. R. Watson (May.22): A single specimen of the true armyworm was
sent in from Monticello. This is the first report of this insect in
Florida for many years.

Mississippi, C. Lyle (May 24): An unusual outbreak of the true armyworm
occurred in the Mississippi Delta the last of April and the first half
of May. The first specimens were received from Vicksburg on April 2b.
Complaints were then received from Sharkey, Tallahatchie, Leflore, Sun-
flower, Washington,and Bolivar Counties. The chief damage occurred on
oats and some fields were practically destroyed before control measures
were emriloyed. Alfalfa was attacked in some fields.

Missouri. L. Haseman (May 13): Armyworm moths were present from about May 3
to 7 in central Missouri, sucking nectar from apple blossoms in such
numbers as I have never seen them before at this time of the year. With
a flashlight I was able to detect as many as a half a dozen to a square
rod of tree surface. ('.ay 26): The first report of serious damage to
small grain, especially barley, came in on May.20 and 21, from southeast-
ern and southwestern Missouri. At that time the worms were large enough
to be literally destroying some barley fields. This morning the county
agent at Springfield told me the arryworms were ruining barley in Greene
County. The Sikeston area in southeastern Missouri, tho Springfield area
in southwestern Missouri, and the Joplin area in southwestern M1issouri
are badly overrun. Half-grown worms are doing serious dr-ma-e to small
grains, meadows, and pastures in the southern third of LUissouri and simi-
lar injury is expected during the next two weeks throughout central and
possibly northern Missouri.

Arkansas. D. Isely (May 20): The most extensive outbreak of armyworms on
record in Arkansas cam. to a head during the last 2 weeks. The principal
damage has been to winter oats. This injury has been most acute in eastern






-164-


and southeastern' Arkansas. In a large part of this area all oat fields
have been rather generally infested. In Arkansas County, where there are
approximately g0,000 acres of winter oats, probably one-fourth of the
crop was lost. Scattered injury has appeared in other counties of the
northern part of the State. This injury.is spotted, occurring only in
occasional fields, and in spots within the fields. There has been some
damage to row crops and pastures. Migrations of arrmyworms have usually
been from oats to other crops. The outbreak is in Benton, Boone, Washing-
ton, Crawford, Franklin, Independence, Pulaski, Lonoke,-Prairie, Saint
Francis, Monroe, Lee, Jefferson, Arkansas, Phillips,.Lincoln, Desha, Drew,
and Chicot Counties. It now seems to be well under control.

Fort Smith American (May Ig): Crops in'the immediate vicinity of
Fort Smith, Sebastian County, are being damaged'seriously by armyworms.

Oklahoma. C. F. Stiles (May 20): The true armyworm is present throughout the
State. It is severely injuring all small grains, especially wheat, rye,
and barley. This isthe most severe outbreak Oklahoma has experienced.
Heat that a week ago would have made 40-bushels per acre is now not worth
cutting, and the ravages continue unchecked. (May 27): Armyworms are
devouring everything in northeastern Oklahoma.'

F. A. Fenton (May 24): On May 13 a report was received of infesta-
tion from the true armyworm at Grandfield, Tillman County, in southwestern
Oklahoma. Following this,' calls for help were. received from widely scat-
tered counties--Jackson, Comanche, Cotton, Caddo, Grady, Garvin, and
Jefferson-- in the southwestern part of the State. The infestation ex-
S:' tends across Oklahoma into Osage County and to the Kansas border. The
damage is mostly in wheat, but oats and barley are also being injured. The
larvae are beginning to move out into row crops, mostly corn and cotton.

Texas. F. L. Thomas (May 17-21): Armyworms reported in wheat and causing
injury in Wilbarger, Clay, and Grayson Counties on the Red River. They are
about two-thirds grown.

FALSE WIRE7ORMS (Eleodes spp.)

South Dakota. H. C. Severin (May 21): The plain.'false wireworm (E. opaca
Say) is extremely abundant in the drier areas' of South Dakota and 'is doing
much damage to wheat..

Nebraska. M. H. Swenk (May 12): The latest report of the season for the Plains
false wireworm was on May 12, when these pests were reported to be dam-
aging the roots of wheat plants. in Hitchcock County.

Idaho. C. Wakeland (May 25): Larvae of E. hispilabris Say and E. extricata
Say are injuring spring-planted and fall-planted wheat in dry-farming
areas in eastern Idaho. A control district operating in Teton expects to
distribute poisoned bait over an area of approxima'elt 10,000 acres'hot'
treated last fall. Approximately 15,000 acres were poisoned last fall.








CORNPJ

CORN EAR WORM (Heliothis obsoleta F.)

Georgia. T. L. Bissell (May 25): A young peach orchard at Ze'bulon, central
Georgia, has bean attacked by larvae eating into the fruit. ?he orchard
was planted in Austrian winter peas, which have just been turned under.

Florida. H. T. Fernald (May l14): Youn.- corn at Orlando has been badly attacked
by what the farmers call the "budworm." I think it the corn ear worm and
WT. W. Others confirms this. The attacks were most severe the latter part
of April.

Alabama. J. M. Robinson (May 26): The corn ear worm is attacking cornstalks
in Opelika.

Mississippi. J. Milton (May 24): Tomatoes at Florence are being seriously
damaged.

Louisiana. L. 0. Ellisor (May): The corn ear worm is seriously damagainr
tomatoes in the southern part of the State. Corn is also being damaged.

California. J. Wilcox (May 10): A sixth-instar larva was swept form alfalfa
at Artesia on May 4, and on May 10 larvae from first to fourth instar were
found feeding on the leaves and tassels of corn at Vernon, Los Arn,-7les
County. Several eggs of the tomato fruitworm were found on tormito plants
in the field in Orange and Los Angeles Counties, and a comparatively large
number of moths emerged last week. Scattered emergence of moths has been
taking place since February 19. On May 3 M. W. Stone found first- and
fourth-instar larvae feeding on strawberries he had purchased at Stanton.
(May 25): About 25 percent of the tassels in a field of early sweet corn
at Vernon, Los Angeles County, are infested with larvae from first to
fourth instar. The larger larvae had moved from the tassels to the newly
formed ears. Sweet corn from Indio, Riverside County, on the market was
found on May 17 to be infested. A full-grown larva was found in a green
tomato at Costa Mesa, Orange County, on May 19. Moth emergence has con-
tinued heavy at Alhambra, Los Angeles County.

SUGARCATE BEETLE (Eaetheola rugiceps Lec.)

Mississippi. C. Lyle (Ma- 24): Complaints of serious damage to corn were
received from Vaughn on May 4 and from Cruger on May 19.

Louisiana.' J. W. Ingram (May 19): Beetle injury to sugarcane began in March
and reached its peak late in April and early in May in southern Louisiana.
Injury is practically over now as few freshly injured plants can be found.
Losses have been about the same as in 1936, which is below the avera-e for
the last 10 years. As in past years, injury was heaviest in the section
west of the Atchafalaya River.

SPOTTED CUCU7ER BEETLE (Diabrotica duodecirommnctata F.)

South Carolina. F. Sherman (May 24): At Florence in eastern part of State
damage is considerable in low, heavy soils but not severe in uplands as
reported by J. G. Watts.








Georgia. T. L. Bissell (May 14): Budworm injury to corn is noticeable at
Experiment, in central Georgia. Larvae are about full-grown..

Louisiana. C. E. Smith (May 20): Injury to corn at Baton Rouge brby the larvae
occurredlarge,3yduring the period from April 18 to 26. In some localized
areas 75 percent or more of the stands were destroyed.,

IMBRICATED SNOUT BEETLE (Epicaerus imbricatus Say)

Missouri. L. Haseman (May 26): Reported as doing serious damage to corn in
the northwestern corner of the State. Present in scattered numbers in
central Missouri.

CORN FLEA BEETLE (Chaetocndma pulicaria Melsh.)

Z. P. Metcalf (May 29): The corn flea beetle is occurring on corn throughout
the State in more than usual abundance.

ALFALFA AMD CLOVER

PEA APHID (Illinoia ps Kltb.)

Virginia. A. M. Woodside (May 22): Alfalfa near Timberville has been very
heavily infested by an. aphid, presumably the pea aphid. Some stands were
practically killed out. ...

Louisiana.. C. L. Stracener (May): Pea.aphid is still active. ..

Kansas. H..R.Bryson (May 23): The pea aphid occurred all over the State in
alfalfa fields but the alfalfa has made sufficient growth to prevent
injury. The population reached a relatively high point by the middle of
May but is now receding.

W. T. Emery (May 18): This insect has been: so scarce in Kansas since
the fall of 1935 that no infe-stations or even individual specimens have
been taken in extensive sweeping until this spring, when it is being found
in abundance in alfalfa, around Manhattan.

Idaho. 'C. Wakeland (May 25)" The pea aphid is fairly abundant on alfalfa in
southwestern Idaho but is relatively scarce on adjacent peas, the earliest
.of which were in early blossom stage on May IS.

Utah. G. F. KnowlUoh (May 8)9 Pea aphids are becoming increasingly abundant
in parts of2 nor-the U'TJh and less abundant i-n. most of Cache and Morgan
Counties, Seconm:-u UeJtion adults are- now present on alfalfa. (May 27):
.ea aphids conti1,i(, o increase in abundance on alfalfa but are not yet
seriously thrb 'atui:- 3 he pea crop. Aphids-v wre for-nd to be the most
abu-ndant on peas at I.apleLn Bench, in Utah Cu,. and at Layton, in
Davis Corn'- ....
Washington ar-d. Ore.on. L. P. RichImond and M. M. Reeher (April): I. pisi is
somewhat more abundant than last year east of the Cascade Mountains in the
Yakima and Columbia Valleys and in the Vrrigated section's 'of Umatilla
County, Oreg. Fields in sandy areas and near the large rivers showed the
highest populations and in these fields from 5 to 10 percent were already
alates. No damaging populations were found. Coccinellid beetles were


-166-








much less abundant than last year.


OreCon. L. P. Richmond and M. H. Reeher (May 7): I.pisi showed a low winter
survival on alfalfa after the long, dry fall and cold winter. The survi-
val on fall-sown vetch and peas was very light and only a few fields came
up in time to become infested last fall. Aphids increased slowly in April
but it is believed that natural enemies will keep them in check. :To damage
to alfalfa and fall-sown legum s. No signs of migration from alfalfa to
annual legumes, although alates are present at the rate of about 4 percent
of the population on alfalfa in some fields and there have been a few warm
days. Coccinellid adults, especially Coccinella trifasciate L., outnumber
the aphids in some fields and there are many syrphid flies.

ALFALFA "EEVIL (Hypera postica Gyll.)

Utah. G. F. Knowlton (May 17); Adults are present in considerable numbers in
many northern Utah localities, from 0.3 to 1.25 being taken per sweep of
the insect net on alfalfa. Fifteen adults and some larvae were taken in
15 sweeps at Draper. (May 27): Alfalfa weevil injury is increasing, but
is light to moderate in most of the fields examined in northern Utah.

Nevada. G. G. Schweis (May 25): Alfalfa weevils have been reported as hatch-
ing in great numbers in Douglas County. From observations in the field,
it is believed that hatching is at least 2 weeks late.

California. A. E. Michelbacher (May 21): A survey of the alfalfa weevil sit-
uation'on May 14 gave the following results: In the San Joaquin Valley
the larval count per 100 sweeps of an insect net for different fields
ranged from.7 to 210, while the adult count ranged from 15 to 37- In
Pleasanton the larval count ranged from 43 to 330, and the adult count
from 0 to 4. In the San Francisco Bay district the larval count ranged
from 35 to 53, and the adult count from 0 to 1. On May 5, parasitization
of the large larvae by Bathyplectes curculionis Thos. in the San Joaquin
Valley averaged more than 90 percent, a marked increase over that found
on April 28. In the most heavily infested field in Pleasanton parasitiza-
tion was S6.5 percent, the lowest encountered this season. Parasitization
in the San Francisco Bay district was greater than 90 percent, although on
April 30 it dropped to 57 percent in the most heavily infested field,
which was also suffering from neglect and delayed cutting.

CLOVER LEAF TEVIL (Hypera punctata F.)

Ohio. T. H. Parks (May 24): The clover leaf weevil has been more abundant
than usual in clover and alfalfa generally.

Indiana. J. J. Davis (May 27): The clover leaf weevil has been unusually
abundant and caused considerable dam.'ge. The first specimens were re-
ceived on ..y 7 from Lebanon in central Indiana. Since that time speci-
mens have been received from localities over much of the State. Clover is
the crop attacked, except in one report which mentioned alfalfa as the food.










Kentucky. W. A. Price (May 24): Damage to clover and young alfalfa plants
was severe in many places in the State, particularly at Hbrse Branch,
-- Shelbyville, Maysville, Lexington, and Louisville.

Michigan. E. I. McDaniel (May 26): The other day we received a quantity of
clover leaf weevil from Eaton Rapids where it was attacking a large field
of closer. About 2G acres of alfalfa clover was involved.

Iowa. C. J. Drake (May 19): The clover leaf weevil showed up in a number of
counties in southeastern Iowa, but little commercial damage has been
reported.

Kansas. H. R. Bryson (May 20): Reports from northeastern Kansas indicate that
the clover leaf weevil, is abundant.

GREEIT CLOVR WORM< (Plathypena scabra F.)

Virginia. A. M. Woodside (IMay 22): Alfalfa in the vicinity of Timberville
was found to have a moderate infestation of the green clover worm.

Louisiana. L. 0. -Ellisor (May): The green clover worm was present on alfalfa
throughout the winter in southern Louisiana. The caterpillars were not
sufficiently abundant. at any time to cause serious damage..

VETCH

VETCH BRUCHID (Bruchus brachialis Fahraeus)

North Carolina. J. S.Pinckney (May 31): Egg deposition by the vetch weevil
began on May 19 at Salisbury, Rowan County, and has about reached its
peak. Egg deposition is heavy and is general over all of the central part
of the State. The first larva wvias found on May 2 Four new 'counties
have been added to the distribution, viz., Burke, Caldwell, Polk, and
Rutherford, infestations having been discovered on May 28. ,

SUGARCANE

SUGARCA1IE BORER (Diatraea saccharalis F.)

Louisiana. E. K. Bynum (May 18): The number of live borer stages found to
have overwintered in replicated overwintering experiments, where treat-
ments were similar, was several times greater this year than in 1936.









FRU I T I N SE C T S


CHERRY SCALE (Aspidiotus forbesi Johns.)

California. S. Lockwood (May 5): Yesterday Forbes scale was found by the
writer on toyon in Yolo County. This, I believe, is the second r/ort
on.the presence of this scale in California and represents to us a new
county infested and a new host.

APPLE

CODLING MOTH (Carpocapsa pomonella L.)

New York. D. W. Hamilton (May 24): Pupae were found as early as May 10 at
Poughkeepsie; however, no emergence has occurred to date. A heavy second
brood in many orchards in 1936 and a mild winter, with a minimum tempera-
ture of 40 F., indicates that a heavy flight of spring brood moths may
be expected.

Pennsylvania. H. N. Worthley (May): Moths were first taken in bait pails
on May 19 in south-central Pennsylvania and began to emerge in cages on
the tree trunks on I'hy 20. This is 9 days later than in 1936. Winter
carry-over of larvae has been heavier than in recent years.

Delaware. L. A. Stearns (May 22): Pupation of over-wintered larvae on May 16
was 94 percent; first emergence of spring-brood moths in southern Dela-
ware on May 6 and in northern Delaware on May 14; first moths collected
in bait -pans on May 13; first first-brood eggs deposited, May 16; no
larvae hatched as yet. Development delayed a full week, as compared
with 1936.

Virginia. A. M. Woodside (May, 15): Moth emergence started late in Augusta
County.and has been slow. The first moths were taken in bait traps on
May 15, although a few emerged in the lofts of packing sheds as early as
May 10.

Georgia. C. H. Alden (May 22): Spring-brood emer.e-nce about over. First-
brood eggs hatching and half-grown larvae noted in apples at Cornelia,
northeastern Georeia.

Ohio. T. H. Parks (May 24): Adults were first caught in bait pans in Law-
rence County, southern Ohic, on May 17, and at Columbus on May 23. With
one or two exceptions, the nights have been too cool for egg laying and
development is 10 days behind that of 1936.

Indiana. J. J. Davis (May 27): Codling moth wintered in large numbers, but
the cold, wet weather prevailing up until a week or 10 days a.-o, has
delayed emergence and egg laying. No emergence north of Lafay-;tte,
according to our observations. The first e-gs hatched at Orleans on
May 27.

-170-


L. F. Steiner (May 26): Spring-brood emergence, as indicated
by bait trap captures at Vincennes began on May 9, but there was very
little activity until May 17. Since then there has been a stesdy increase
in moth abundance. Activity is now at, or very near, its .peak. The
first entrances were found today. In extreme southwester,Indiana adult
activity apparently reached its peak on May 20. Moths now-appear to be
more abundant than at any time during the 1936 season.

Illinois. W. P. Flint (May 24): Adults are emerging over the entire southern
half of the State. From present indications, the winter survival has
been high and a-heavy first brood is indicated.

Kentucky.. W. A. Price (April 30): Our first record of moth emergence this
season was on April 30 at Paducah.

Michigan. R. Hutson (May 20): Over 50 percent of codling moth have pupated
in the vicinity of Shelby, Grand Rapids, and Fennville.

Missouri. L. Haseman (May 26): The peal of first-brood moth emergence is
occurring in the Marionville district, southwestern Missouri. We are
expecting the peak to be reached by the end of this week or the first of
June in central'Missouri and in the St. Joseph and Louisiana, Mo., areas.

Arkansas. D. Isely (May 20): Codling moths are unusually late this season,
with no appreciable emergence in northwestern Arkansas until after May 1.

Washington. E. J. Newcomer (May 21)': Emergence began on May 4 in Yakima
County; but has been slow on account of cool Weather. A few eggs. were
found on May 18. The season is about 2 weeks later than last year.

EASTEPRT TENT CATEPILLAR (Malacosoma americaha F.)

Maine. F. H. Lathrop (May 19): Newly hatched larvae were observed on apple
trees at Orono, in Penobscot County, on April 30. By May 12 the nests
were beginning to be noticeable on wild cherry trees along the roadsides
in Kennebec and Androscoggin Counties.

Vermont. J. V. Schaffner (May 24): Noticed caterpillars hatching on April 20
at Springfield. Infestations rather general and heavy in Bennington and
Windham Counties.

Massachusetts. J. V. Schaffner (May 24): Apple arnd wild cherry trees are
heavily infested in many localities through Berkshire, Franklin, Hampden,
and Worcester Counties. P. A. Berry reports that the tents are notice-
able in the eastern part 6f the State.

Connecticut. W. E. Britton (May 13): Although abundant in some locaiities,
in general throughout the State this insect is less abundant than in
1935 and 1936.






-171-


B. W. McFarland (May 13): Infestations at Bloomfield, East
Granby, and Windsor are the worst that have been observed in these three
localities during the last few years. Nests were found in three white
pines and the caterpillars were attempting to feed on the trees.

J. V. Schaffner (May 24): The eastern tent caterpillar is abun-
dant in many localities throughout the western half of Connecticut.

New York. R. D. Glasgow (May 22): Abundant again this spring in many parts
of eastern New York. The so-called wilt disease of this caterpillar,
reported from parts of Albany County somewhat later in the spring of
1936, is appearing in other parts of the county this year.

R. E. Horsey (May ll): Unusually abundant on apple, ornamental
crab apple, flowering and fruit cherries, and wild plums at Rochester.
First noted on May 2, when the caterpillars were inch long and webs
11- inches in diameter. Still hatching at this date, M'Ly 11. A ride
through the country south of Rochester on May 9 found them numerous.

N. Y. State Coll. Agr. News Letter (May): The tent caterpillar is
abundant in the apple-growing sections of both eastern and western New
York.

Pennsylvania. H. N. Worthley (1.4?y 21): Tents are now conspicuous on wild
cherry and neglected apple trees. Between State College and Gettysburg
the infestation is not as heavy as in 1936.

Indiana. J. J. Davis (May 27): Again showing up in unusual numbers in some
parts of the State; in fact, they are so"abundant on some trees that food
is scarce and disease is making quite an inroad.

PISTOL CASEBEARER (Coleophora malivorella Riley)

Pennsylvania. H. N. 7orthley (May 21): Becoming increasingly abundant in
south-central Pennsylvania. Overwintering-larvae moved from the twigs
to the opening buds in mid-April. Signs of their feeding are now common
on the newly set apples and on tender terminal growth.

FLATHEADED APPLE TREE BOTF. (Chrysobothris femorata Oliv.)

Michigan. R. Hutson (Ma.- 20): Reports are coming in daily. We have recently
heard of infestations in Battle Creek, Vestaburc.-, Grand Rapids, Howell,

Maine. F. H. Lathrop (May 19): A few recently matured adults of Rhopalosiphum
prunifoliae Fitch were found on anapple tree in Monmouth, Kennebec County,
on May 12. This species is very scarce on apple trees in this section.
Newly hatched nymphs of A. pomi Deg. appeared on apple buds at Monmouth,
in Kennebec County, during the week ended April 30. This species seemed
to be slightly more abundant. than usual. Small colonies could be found
on apple buds in commercial orchards. Cold, rainy weather during the
first 2 weeks in May reduced the-number of aphids. By May 15 they were
difficult to find.

Connecticut. P. Garman (May 19): Anuraphis rosae Baker is unusually scarce
in New Haven County.

New York. N. Y. State Coll. Agr. News Letter (May): Fruit aphids in general
are less abundant than usual throughout the State. Ladybird beetles have

two species is higher than usual, and the first-named species is somewhat
abundant in isolated infestations.

Indiana. J. J. Davis (May 27): Rosy- apple aphid is reported by G. E. Marshall
as increasing rapidly at Orleans and doing considerable damage.

Michigan. R. Hutson (May 20): Orchard surveys indicate the rosy apple aphid
is comparatively scarce in all apple-growing sections.

McAtee were observed on the under side of apple leaves near.,Monmouth on
May 12.

New York. N. Y. State Coll. Agr. News Letter (May): The first nymphs of
T. pomaria were observed on May 6 and 10 in the Hu.ason River'-.Valley and
on May 17 and 20 in western New York.






-175-


Connecticut. P. Garman (May 19): Nymphs of the white apple leafhopper are
present in about the usual numbers in some orchards in New Haven County.
Scarce or absent in others.

Indiana. J. J. Davis (May 27): Leafhopoers are abundant on apples. The
first nymphs were observed by G. E. Marsh--.] 1 at Orleans May 24.

Kentucky. W. A. Price (May 214): Leafhoppers are more abundant than usual
at this time of year in orchards in the Paducah area. The species most
a'unrant are Erythroneura obliqua Say !nnd E. lawsoniana Bak.

Missouri. L. Haseman (May 26)': Apple leafhoppers are much less abundant than
for the last several years.

E'.TROF1AI RED MITE (Paratetranychus pilosus C. & F.)

Connecticut. P. Garman (Mwa 19): European red mite generally scarce through-
out New Haven County.

Pennsylvania. H. N. Worthley (May 21); In Adams County (south-central Penn-
-sylvania) first--rn ration mites are mature, and the first eg.:s were seen
on apple leaves on May 17. The mites are moderately abundant where dor-
mant control measures were omitted. At State -College (central Pennsyl-
vania) the mites are very abundant on unsprayed trees. ;:-s have not yet
been observed.
PEACH

PLUM CURCULIO (Conotrachelus nenuphar Hbst.)

Maine. F. H. Lathrop (May 19): Overwintered adults were active in hiberna-
tion cages at Monmouth on May 11.

Delaware. L. A. Stearns (Maiy 22): First overwintered adults collected by
jarring at Bridgeville on April 23, which was also the peak of emergence
to date.

Georgia. 0. I. Snapp (May 19): The curculio infestation at Fort Valley
(central Georgia) is very light. It it- perhaps the lightest infestation
in the 18 years during which this insect has beer. under observation in
central Georgia by me. This is believed to be due to the lighter than
usual carry-over of adults and to the high mortality during hibernation.
The first full-- -w?. larvae began to leave peach drops on lay 4, which
is from 2 to 3 weeks later than usual.

C. H. Alden (May 22): First-brood larvae full-growrn, leaving the
peaches, and making cases in the soil at Cornelia.

Missouri. L. Haseman (May 26): No evidence of the plum curculio has shown
up at Columbia or Clarksville.

SEED CORN MAGGOT (Hylen yiacilicrura Rond.)

Maryland. C. F. Andrus (May 31): From 16.5 to 60.0 percent of the seedlings
in two i-acre plots of bea- s planted on May 4 at Beltsville were des-
troyed by an unusually concerted attack of seed corn maggots. Counts
made on May 20, based on a total of 2,607 plants from small samples,
showed an average of 32.5 percent destroyed in one plot and 38 percent
in the other. The above percentages of damage represent only seedlings
in which the primary leaves were' completely' destroyed. A large propor-
tion of the remaining plants showed various degrees of injury, as did
also the seedlings that had not yet emerged above the soil on the date
of observation. It is estimated that not less than 70 percent of. the
early seedlings in these two plots 'were infested in some degree. Seed
planted 1 week later in the first plot produced seedlings only 10.5 per-
cent of which were seriously damaged by the maggot.- Of 869 seedlings

fungous disease, predators, and other factors have greatly reduced its
numbers and it is becoming rather scarce,

Ohio. N. F. Howard (May17): The pea aphid is not now very abundant on a
planting of peas at South Point but it was abundant.last week. Natural
control was probably due to heavy.rains. Cocciniellids becoming numerous
and first-generation larvae are pupating. The planting was seriously
injured, the tips of the plants being malformed and stunted.

SUGAR :!FTS

BEET LEAFHOPFER (Eutettix tenellus Bak.)

Idaho. J. R. Douglass (May 24): *The spring brood of leafhoppers in south-
central Idaho is comparatively large owing to the moderately high spring
population of overwintered leafhoppers and an abundance of favorable host
plants on which to reproduce. The warm, dry weather of May has been
favorable for the early development of the spring brood; therefore the
migration into the cultivated areas will begin about June 1 and should
reach the peak about June 18. Already there are a few overwintered leaf-
hoppers within the cultivated area but this is a normal occurrence, as a
few of the insects remain within the cultivated area each winter.

Utah. G. F. Knowlton (May 17): Beet leafhoppers were rather abundant on sugar
beets west of Provo and less abundant at Plain City, in northern Utah.

H. E. Dorst (May 25): Large long-distance mi-ration of beet leafhoppers
from southern Utah, southern Nevada, and northern Utah, extended from
Richfield to the Idaho State line on the north. Migration of April 23 to
May 20 reached the beets while they were in the cotyledon stage and
reached the tomato-growing district from Payson to Garland during plant-
ing time.

BEAN APHID (Aphis rumicis L.)

California. A. E. Michelbacher (May 21): An aphid believed to be A. rumicis
was doing serious injury to a sugar-beet planting near Stockton on May 7.
The beets were literally covered with the pest.

HOP FLEA IEETLE (Pcylliodes punctata Melsh.)

Utah. G. F. Knowlton (May 22): Hop flea beetles are damaging sugar beets in
northern Utah and injury to young seedlings is reported as very severe
in Gunnison Valley. Replanting due to this cause is reported in a number
of instances.
TOBACCO

TCOBACCO -HOR,,FCR;S (Protoparce spp.)
North Carolina. J. P. Vinzant (May 25): First rs observed this year were
found on tobacco in the field on I-y 24 at Oxford.

S ing-numerous in a few fields of sun-grown tobacco in. Gadsden County.

CORN ROOT WEBWTRM (Crambus caliginosellus Clem.)

Tennessee. L. B. Scott (I1a'- .25): The sd-called tobacco wirewormf is present
on tobacco in about 'normal numbers in Montgomery County.

TOBACCO FLEA BEETLE (Epitrix parvula F.)

North Carolina. Z. P. Metcalf (May 29)-.: The tobacco/ flea beetle is about as
abundant in the entire State as'it was last year.
South Carolina. W. C. Nettles (May 21): Considerable damage was apparent
early in May in the Pee Dee district but dimin-ished about: May 20.

Florida. F. S. Chamberlin (June 1): The second brood of tobacco flea beetles
has emerged in Gadsden County and appears to be more abundant than usual.

Tennessee. L. B. Scott (May 8): Less numerous than usual in western Tennessee,
with very slight damage. (Mlay 25): Present in less than normal numbers
in northwestern Tennessee. Has increased slightly since May 20 but damage
in tobacco plant beds is negligible. .

Kentucky. W. A.Price (May 24): Flea beetles in tobacco beds have been
moderately common.

POTATO FLEA BEETLE (Epitrix cucumeris Harr.)

Massachusetts. A. W. ,Morrill (May 15): Tobacco seedlings in seedbeds attacked
in localized areas. Affected plants severely damaged. First severe case
noted this season at Southwick, Hampoden County.

TOBACCO THRIPS (Frankliniella fusca Hinds)

Florida." F. S. Chamberlin (May 12)-: Owing to hea-v rains during the first
part of May, very few thrips a';re present in the tobacco fields of this
region (Gadsden County), No damage to date.

APHIDS (Aphiidae)

Tennessee. L. B. Scott (May 25): Aphid (undetermined) has caused many com-
plainrts from growers near Springfield. The damage is not severe, but very
noticeable in many plant beds. The presence of aphids on tobacco in this
section is rather unusual.

GARDEN FLEA HOPPE (Halticus citri Ashm.)

Florida. F. S. Chamberlin (May 17): -,This insect is much less abundant on
tobacco than normal. Damage slight in Gadsden County. (Det. by H. G.

BOLL WEEVIL (Anthonomus grandis Boh.)

South Carolina. F. F. Bondy and C. F. Rainwater (May 15): Weevils in Flor-
ence County are emerging in the fields in apparently larger numbers than
for the past 3 years. The average of all fields examined was l15 weevils
per 10,000 plants. (May 29): The following table, giving the emergence
of boll weevils in the hibernation cages at Florence for the past 6 years,
shows that the 1936-37 winter mortality was not as high as during the
previous 3 winters.

brood is the smallest in many years.

Mississippi. C. Lyle (May 22): Examinations wer- -e c' 3 l farms in 10 coun-
ties during the last week and weevils were fou.id in o 1' I field.

E. W. Dnnam (Hay 15-29) No weevils have been reported in Wash-
ington County.

Louisiana. R. C. Gaines and assistants ('ay 22): In Madison Parish the fol-
lowing record of boll weevils taken on nine flight screens is reported,
in comparison with previous years.

From present indications, weevils are more numerous in the vicinity of
Tallulah than they were a year ago at this time but less numerous than
during the last week in May of the 4 -nrecedinp :-rers. Apparently there
was a higher survival of weevils this .pring than following any winter
since 1932.






-190-


Texas. F. L. Thomas (May 15): The emergence of boll weevils at College
Station has exceeded 6 percent and is already greater than the 11-year
average. (May 22): Weevils are continuing to emerge from winter quar-
ters and their numbers are increasing in the fields. As many as 455 per
acre were found in one field in Dimmit County. (May 29): Weevils are
reported in Nueces County.and have: 'been. found to average 130 ppr acre in
a few fields of Bexar County. The emergence totals more than 9 percent
and has been exceeded only three times in 12 years..

R. WT. Moreland (May S-15): On 1,200 cotton plants in Brazos and
Burleson Couinties in 3 fields of unchopped cotton 11- weevils were found
and on 00 plants in 3 fields where the cotton had been chopped 16 weevils
were found.

K. P, Ewing ,(May g): In Calhoun County indications are that there are
not as many boll -weevils this year as last, although numbers are higher
than nov.mal. (May: 1.5): This week there was a considerable increase over
last in the number of weevils found in cotton in the river bottom in,
Jackson -County, which indicates thay they are still coming out of hiberna-
tion. Examination of 5,600 cotton plants in 11 fields showed an average
of 1.6 weevils per 100 plants, as compared to 0.3 per: 100 found last week.
In Calhoun County 5,700 plants in 28 cotton fields were inspected arid an
average of 0.18 weevil per 100 plants -was found, as compared to the pre-
vious week (May 8) of 0.15 per 100 plants. (May 22): In the Layaca
River bottom, in Jackson County, in the examination of 2,200 plants in
5 fields the average number of boll weevils per 100 plants was 2.32 this
week, as compared to 1.6 last week. All of this increase was in one
field where the cotton had grown unusually large and there was a concen-
tration of weevils in this field. The other 4 fields showed about the
same infestation as during the previous week. In 1,700 cotton plants in
47 fields in Calhoun County the average boll weevil per 100 plants was
0.106, a reduction from an average of 0.l1 per 100 plants the previous
week. The decrease was probably due to the fact that more fields in the
op-en prairie were inspected this week. (May -29): In the Lavaca River
bottom, in Jackson County, 1,300 cotton squares were inspected in 4
fields; the boll weevil infestation averaged 3'9 percent punctured
squares and there were 2.8 adult weevils per 100 squares. The maximum
infestation was 50 percent and the minimum, 25 percent. In Calhoun
County no boll weevils wore found on 17,300 cotton plants examined for
cotton flea hoppers, but this was not a true index of infestation, as
the weevils have left the terminal buds and are now on the larger cotton
squares.
Florida. H. C. Young, J. T. Roy, and K. H. Smith (May 1): No boll weevils
have been found in cotton fields to date. Indications are that emergence
will be light throughout the State. (May 15): In Alachua County weevil
counts were made in 17 fields and only 9 were infested. The number of
weevils ranged from 20 to 170 per 10,000 plants, the average for all
fields being 35 per 10,000 plants. (May 22): In Alachua County 24 fields
were inspected and weevils were found in 18. The number of weevils
ranged from 10 to 275 per 10,000 plants in the infested area, or an aver-
age of 47 per 10,000 plants in all fields examined. (May 29): In Alachua







-191-


County 16 of the 21 fields examined were infested with weevils. The
number of weevils in the infested fields ranged from 13 to 220 per
10,000 plants. The average population of all fields examined was 56 weev-
ils per 10,000 plants.

COWPEA CURCULIO (Chalcodermus aeneus Boh.)

Georgia. T. L. Bissell (May 27): Adults are seriously damaging young cotton
at Fort Valley in central Georgia, by feeding into the stalks and leaf
petioles. About 20 percent of the plants in one field, where coipeas
were grown in corn last year, are killed.

PIVK BOLLWORM (Pectinophora gossypiella Saund.)

Texas. A. J. Chapman (May 1): At Presidio there was a heavy emergence of
moths from the hibernation experiments during the week, indicating a
heavier survival than last year. (May 15): There has been a reduction
in emergence from all the hibernation tests except the one irrigated on
April 20. The emergence indicates a higher percentage of survival than
last year.

COTTON LEAF :7..:. (Alabama argillacea Hbn.)

Texas. F. L. Thomas (May 27): The cotton leaf worm was reported from Nueces
Court-,. toda-y.

K. P. Ewing (May S): In Calhoun County no leaf worms have been found.
Last year the first one was found'on May 5-

Correction.--The locality for the cotton leaf worm reported in the
Insect Pest Survey Bulletin, June 1936 (vol. 16, p. 97), should have been
Port Lavaca, Tex., instead of Port Tobacco.

COTTO:T FLEA :{O7?ER (Psallus seriatus Reut.)

South Carolina. F. F. Bondy (May 15): One cotton flea hopper nymph found in
Florence County.

Mississippi. A. L. Hammer (May 24): The cotton flea hopper is rather common
on cotton at State College.

Louisiana. R. C. Gaines (May 15): In Madison Parish 94 adults and 11 nymphs
were found in 300 sweeps on evening primrose. In 500 sweeps near Tendall
36 adults and 2 n:.yr.h,; wore t1-' r.. .To sweepins-- were made during the
same week last year but the number found this week was greater than that
found during the last week of May in 1936.

Texas. F. L. Thomas (M'ay 8): Flea hoprcrs are more abundant in central Texas
than in the more northern counties. (May 29): Control measures have
been started in some counties of southern Texas. There are'but.few fields
in the central part where control measures would be justified.







-192-


K. P. Bwin .(May-8 g): At Port Lavaca, .in !Calhoun County, there was a
decided increase, in the number of flea 'hoppars found on the screens and
also in the cotton fields this week, as compared.to last. week. (May 15):
There was a decrease this week over last in the number of flea hoppers
found on the screens and also in the cotton'fields. There was also a de-
crease in the population on horsemint and evening primrose.
COTTOIT APHIDS (Aphiidae)
Georgia. P. M, Gilmer (May 15): In southern Georgia a few aphids were found.
Most of these have been parasitized.
Florida. H. C. Young (May 1): At Alachua a few aphids were noted in some fields
South Carolina. F. F. Bondy (May 15-29): In Florence County some fields showed
a considerable infestation of leaf aphids.
F. F. Bondy and C. 1. Rainwater (May 22): Root aphids are
killing young cotton and causing serious damage in some fields.
W. C. Nettles (May 21): Cotton root aphids were first noticed
in the coastal section during the first half of May. Considerable damage
occurred in some fields.
Texas. K. P. Ewing (May S): In Calhoun County cotton aphids were found to be
numerous in practically all fields but apparently doing no damage. Predators
seemed to be increasing. (May 15): Predators very numerous and giving
control; aphids considerably decreased in numbers.
THRIPS (Thysanoptera)
South Carolina. J. G. Watts (May 24): Frankliniella fusca Hinds was becoming
abundant on cotton at Florence by May 20.
F. F. Bondy and C. F. Rainwater (May 29): Thrips have done a
great deal of damage to cotton in Florence County.
Mississippi. E. 7. Dunnam (May 20): In Washington County an average of 2.24
thrips per cotton plant were found when the plants were in the four- and
five-leaf stage. Practically all of the thrips were nymphs. Damage is
more severe in the older cotton and some buds are blasted, but vegetative
branches have not appeared. (May 29): The average seedling infestation
of thrips ranges from 2.15) to l.OO per plant. The lighter infestations
are found. in small unchopped cotton and the heavier ones in block-chopped
cotton. Leaf damage is noticeable in most fields, but side branching has
not started.
Louisiana. C. 0. Eddy (May 24): F. fusca was abundant on seedling cotton
throughout the State during the first two-thirds of May. Much injury re-
sulted.
R. C. Gaines (May 15): At the Tallulah laboratory thrips are re-
ported to be appearing on cotton. Counts made in the latin-square tests
showed an average of slightly more than one thrips per plant.
Texas. F. L. Thomas (Ma, 22): In -some fields in central Texas 100 percent of
the plants are infested. (May 29): Injury to cotton has attracted much
att-ention and is reported as severe in DeWitt, Grimes, Burleson, Brazos,
and Madison Counties.









AFN D S H A D E T'R .E-E, IN S.E C T S


fEODICAL CICADA (Magicicada septendecim tredecim Walsh & Riley)

Indian,. L. *F. Steiner (May 26): In certain orchards which suffered a h-'--
attack 13 years ago newly made exit tunnels are extremely abundant. In
one Vincennes orchard adjoining a wooded area many of the trees have more
than 10,000 exit tunnels under them. Emergence began about MLa 25.

Kentucky. W. A. Price (May 20): Theofirst report of the periodical cicada
was received from Mayfield, in western K.ntuckj.

Tennessee. G. M. Bentley (May 28): The periodical cicada has made its appear-
ance at Overton Park at Memphis, Shelby County. It was first observed on
May 23, but apparently the forms made their first appearance in this park
on May 19. It also appeared in Tipton and Lauderdale Counties.

Mississippi. C. Lyle (May 21): Reports throughout northern Mississippi in-
dicate that Brood XXIII of this insect is now appearing in lrrgr numbers.
Specimens were received from Grenada on May 17, including some of the
variety cassinii Fisher. On May 22 they were reported from all over
Tippah County'and on the same date were very abundant in Pontotoc, Chick-
asaw, and Alcorn Counties. G. L. Bond reports hearing them recently-in
George, Greene, Wayne, and Jackson Counties.

Missouri. W. F. Turner (Mayt 2g): In Gardner i7tional Forest, in the north-
western corner of Howell County on oaks; also in Gardner National Forest
in the northeastern corner of Douglas County (distinct from colony re-
ported in Howell County; separated by several miles). This colony was
heard along the highway for over a mile.

CAINKERWORMS ET AL (Geometridae)

Rhode Island. A. E. Stene (May 27): Cankerworms are abundant, largely in
Providence County.

trees at Leudonville and is apparently more abundant elsewhere in the
Hudson Valley than last year.

E. P. Felt (i&May 24): Eggs of Ennomos subsignarius Hbn. were
received from Newburgh, indicating a probable local abundance. This
is. occasionally extremely nurr.e-rous and injurious in the Catskill forests.

Ohio. T. H. Parks (May 24): Two or throe species of spanworms were found


FOREST









on a trip made May 14, recently hatched and devouring leaves of oak,
hickory, and elm in farm wood lots of western Ohio. Many of these trees
near Dayton probably will be defoliated, as the outbreak seems to be more
intense than that of a year ago. The spring cankerworm (Paleacrita ver-
nata Peck.)is injuring apple trees in unsprayed home orchards in the
western third of Ohio and is very abundant on many elms in forest and
dooryard plantings.

Missouri. L. Haseman (May 26): One of the heaviest outbreaks of cankerworms
I have seen in many years is showing up throughout central and northeast-
ern Missouri. The larvae are about half-grown at this time and are strip-
ping some large elm trees in the Clarksville district. At Columbia they
are very abundant but not yet seriously stripping trees.

Kansas. H. R. Bryson (May 25): Very little injury has been caused by canker-
worms this year. Two or three areas around Manhattan have experienced
some injury,

Oklahoma. F. A. Fenton (May 24): Cankerworm injury was reported from Okmulgee.

FOREST TENT CATERPILLAR (Malacosoma disstria Hbn.)

Vermont. J. V. Schaffner (May 24): Hatching of the forest tent caterpillars
in Bennington County was general on May 3. The majority of the cater-
pillars were in the third instar on May 22 and the effect of this group
feeding was becoming noticeable, particularly on sugar maple.

New York. R. D. Glasgow (May 22): The forest tent caterpillar, abundant
again in parts. of eastern New York, is reported to have defoliated some
pin oak at Chatham.

South Carolina. F. Sherman (May 24): Forest caterpillar locally abundant in
Dorchester and Berkeley Counties, in the eastern section.

W. C. Nettles (May 21): The forest tent caterpillar was
causing serious forest tree defoliation about May 1 in the lower part of
the State.

Minnesota. J. E. Grathwol (May ll): Hatching of forest tent caterpillar
started about May 11. Very abundant.

GYPSY MOTH (Porthetria dispar L.)

Maine. F. H. Lathrop (May 19): Larvae were observed hatching from egg clus-
ters *in the experimental orchard at Monmouth, Kennebec County, on May 4.
Hatching proceeded very slowly during the next 10 days. On May 16 large
numbers of newly hatched larvae were observed on the experimental trees,
but little or no feeding had taken place. The insect is unusually abun-
dant this spring. In southern Maine it threatens to do considerable
damage in apple orchards located near infested woodland.

and have been ovipositing for about a week.

New York. W. E. Blauvelt (May 24): Adults 'seen on Betula populifolia in
various localities in Westchester, iassau, and Suffolk Counties from
May 10 to 14. Egg laying was well under way by the latter date.

ELM

ELMI LEAF MI4ER (Kaliosysphinga ulmi Sund.)

New York. W. E. Blauvelt (May 24): Adults were first observed on May 1. and
were abundant on May 23 on English elm at Ithaca. Many eggs had been
deposited but none had hatched by May 23-

ELM LEAF =ES'TLE (Galerucella xanthomelaena Schr.)

Massachusetts. J. V. Schaffner (May 24): P. A. Berry reports that the elm
leaf beetles were issuing from hibernation in large numbers at Woburn
the week beginning May 17.

New York. R. D. Glasgow ('a,- 22): The elm leaf beetle, apparently less abun-
dant in the Hudson Valley since 1934 than during the preceding 3 years,
appears to have come through the mild winter in greatly increased numbers.
It is already caisiar' notable injury at Citskill and numerous correspon-
dents earlier this spring reported the invasion of houses by hordes of the
beetles coming out of hibernation.

California. C. S. Morley (May 6): Spraying for elm leaf beetle in Bakersfield
was started the first of this month. The first pests were found feeding
on April 28.

southwestern Vermont, and Montpelier, Washington County, central Vermont.

New York. R. D. Glasgow (May 22): At North Elba on May 12 had nearly all left
,.their hibernation stations and migrated to the newly opening buds. Very
rarely had more than one needle in a cluster been mined. This introduced
insect is slowly destroying the tamarack in northern New York forests.
Large numbers of trees have already died as a result of repeated defolia-
tion and very few trees do not show serious injury.

R. E. Horsey (May 1 and 11): Very numerous this year on Americar, i
Siberian, European, Japanese, and other larches at Rochester; none immune.
First noted on May 1 and still feeding on May 11.

A MIRID (Iielanotrichus mimus Knight (?))

Arizona. T. P. Cassidy (May 6): We have had several cnmplaints recently from
cattle -,eople about the foli'"- on mesquite dying and drying u-p as though
the tree had blight. The reorle arc very much concerned, as they (clpend
largely on the mesquit. foliaj:e for feed until the surner rains occur.
At S,, ,er Ranch a similar situation was reported. The blighted trees were
spotted through the mesquite breaks and wore very heavily infested with
hot-crs; found hopm-rs on all of the mesquite trcc swept, even thouz'h
they did not show signs of blight, but they were not as numerous an the
nonblig',hted trees. (Det. by BarbOr.)

AN LT-DER'JIT: (Catoca inca )

Arizona. C. D. Lebert (M1ay 21): Larvae (species undietcrmine.d) were found by
the thousands under the bark of :ome large mosquito trees in a Phoenix
yard. The larvae cone cut at niht, dro'-) from the trees, cover the lawn
below, and crawl into the home, where they annoy te occupants. Then
disturbed, many of the larva. suspend themselves by a silken thread from
the trees.

OAK

OAK .-'LL (A;dricus corenus Beut.)

New York. 7. E. Blauvelt (.Iy 24): A hea-v7,r infestation was, noted on a fe'i
specimens of pin oak at Ryc., Testchester County, on M1y 10. Most of the
galls had already fallen to the ground.

EUTPOPLAN PITE SHOOT MOTH (Rhyacionia buoliaiw. Schlff.)

New Jersey. J. V. Schiaffner (Macy 22): 7ececnt obeervatlone in the northern
and central parts of w Jersey show that the Eurompean pine shoot moth
is generally distributed throughout this area. In several localities it
is apparent that the infestations are on the increase.

New York. W. E. Blauvelt (,,1y 24): Liht-to-hea-'y infestations in red,
mugho, and Austrian pin.s ,.ere observe" from 11 1, to 15 in various
localities throughout U7stchester, I1assou, and Suffolk Covnties. Tmun-rous
larvae were collected but no pupae iere found.

AN APHID (Cinara sp.).

Virginia. W. J. Schoene (May 24): During the-first week in May flights of
aphids were observed at several points in the State, especially at
Charlottesville, Staunton, and Blacksburg, the insects being so nunmer-
ous ir. some localities as to interfere with building operations. We have
not definitely determined the insect, but it appears to be Cinara sp.

EASTERN PINE BARK BEETLE (Ipo pini Say)

Michigan. E. I. McDaniel (June 2): Specimens of this beetle were collected
on a Norway pine plantation near Pontiac, Oakland County. A number of
young trees growing on a high, sandy knoll had been attacked and several
killed. (Det. by M. W. Blackman.)

SPRUCE

SPRUCE GALL APHID (Chermes abietis L.)

Wisconsin. E. L. Chambers (May 25): A number of requests have been received
this spring for identification and control.

New York. W. E. Blauvelt (May 24): "Tur-rous specimens of Norway spruce in-
fested with old galls and overwintered nymphs were received from various
localities. The overwintered females began laying eggs at Ithaca on
May 8, when buds were just beginning to show green on the more vigorous
trees. Many eggs had been laid by MWy 11 on Long Island, but no hatch-
ing had been observed by 1.4y ].. Picea canadensis was found to be rather
heavily infested at Jamesport on M1ay 13.

A EUCOSMID (Argyroploce abietana Fern.)

New York. W. E. Blauvelt (May 211): Badly infested specimens of blue spruce
were received from Ononta on May 10 and from Bombay on May 18. When
examined on May 18 most of the individuals were in the pupal stage.
Adults started to emerge from this material on May 20. (Identified by
W. T. M. Forbes.)

MOSQUITOES (Culicinae)

United States. G. H. Bradley (May): The first adults of Aedes sollicitans
Walk. were observed near Milford, Del., on May 10 and at Girdletree, Md.,
on May 3. A. cantator Coq. was observed several days prior to May 3.
Salt-marsh mosquitoes had not been troublesome in the coastal towns up
to May 24.

B. V. Travis (May 20): Mosquitoes have been more annoying to
man in the vicinity of Newton, Ga., and Tallahassee, Fla., than in many
years, according to the natives. During, the last 2 weeks it has been
hot and dry and the mosquito population has decreased greatly.

florida. F. C. Bishopp (May 20): A correspondent at Minneola writes, "We
are being eaten alive by mosquitoes. The insects are so numerous that
they sound like a swarm of- bees surrounding the house." A correspondent
at Miami writes, "So far this season we have had very few salt-marsh mos-
quitoes (A. sollicitans and A. taeniorhynchus Wied.), although conditions
have been favorable several times for flights from the areas south of
our ditched sections.

Illinois. F. C. Bishop (May 25): A correspondent at East Saint Louis re-
ported that mosquitoes vrrf so abundant that one could hardly get out of
doors.

There are many more than ever before and they appeared earlier."

Maryland. F. C. Bishopp (May 24): Reports from parts of Maryland adjacent to
the District of Columbia indicate that wood ticks have been.very.numerous

United States. W. E. Dove (May 31): The low point for cases occurred during
the last week of December as compared to the third week of February of
the preceding year. Localized outbreaks occurring in the line of advance
in Jefferson County, Fla., and Camden County, Ga., were brought under
control. At Hinesville, Ga., the first case of the season occurred on
May 25, which was 25 days later than the first case last year, and -40
days later than the first case of 1935. For'the 4-week period ended
May 21, there were 2,575 cases representing about one-half million animals
in Florida. In Georgia 60 cases were reported in the southern counties.
As yet, cases have not been found in western Florida, South Carolina,
Alabama, Mississippi., Louisiana, or in eastern Texas. In California no
screwworms were present in the Imperial Valley during the winter and
most of the animals are now in the higher elevations without infestations.
Screwworms are now present in small numbers in these sections, in three
counties of the southeastern corner of New Mexico, and a few cases are
occurring in Pima and Cochise Counties, Ariz. Throughout this area there
is a low incidence of cases. Much of the shearing was completed in ad-
vance of the spread of screwworms and most of the shear cuts were treated
with pine tar oil. For the 4-week period ended May 21 there were 7,424
cases reported from Texas, representing more than three million animals
of the infested area. The heavy shipments of feeder stock to Oklahoma
and K'nsa3 are about completed and stockman made efforts to ship only
"clean" animals into these areas.

in our pastures have acted -as though they were being annoyed by nose
botflies.
