INSECT PEST SURVEY BULLETIN


Vol. 17 May 1, 1937 To. 3



TE MOBRE IMPORTANT RECORDS FOR APRIL

From northern Indiana and Illinois westward to Montana and Okla-
homa grasshopper'eggs appear to have passed the winter in good condition,
with prospects of moderate-to-heavy infestation over limited areas in
many parts of the territory. The first records of hatching wore made in
Montana on April 21 and in Utah on April 17.

Mormon crickets were hatching during the second and third weeks
in April in Montana, Colorado, Idaho, Utah, and 'Tevada.

Wireworms were reported as doing some daroa.ao in Idaho and south-
eastern Washington.

During the second week in the month first flights of :,' beetles
occurred in Louisiana, Mississinpi, Oklahoro. and Texas. Adults were
also recorded lator in the month from Iowa and Kr.insas.

The usual spring records on cutworm activity are being received
from Florida to Michigan and westward to Missouri and Kansas. Reports
have also been received from the Great Basin and the Pacific coast. In
California considerable damage to tomatoes was reported from the southern
part of the State.

In general, hessian fly infestation is very low.

Cold, wet weather held the chinch bug in hibernation in the East
Central States. These insects are quite prevalent from Ohio to Nebra-sk-a,
and southward to Kansas.

Severe dairage to winter wheat by false wiroworms was reported from
western Nebr-skh; and Kansas.

Rather heavy infestations of wheat by nitas were rooortcd from
Kansas and Okl-ihora. In the latter State considerable injury was observed.

The pea aphid is considerably moro abundant on alfalfa and peas in
the Torfolk section of Virginia than usual. It was 2-lso reported from
Louisiana, Kansas, and Utah.

Thus far, reports from Mississippi to Virginia and westward to
Wisconsin indicate that aphids are comparatively scarce on deciduous
fruit trees.

The first record of collecting adult codling moth was made in
Georgia on April 16. In the East Central States the insect appears to
have passed the winter in good condition and in large numbers.

Tent caterpillar abundance was generally reported along the At-
lantic coast from New Hampshire to Florida. The larvae were practically
full grown in Florida by the middle of March, whereas in New Hampshire
eggs were first observed hatching on April 19.

Serious damage by the flatheaded apple tree borer was reported
from Nebraska, Kansas, and Oklahoma, probably a result of the drought
of recent years.

The mild winter was reflected in heavy survival of the San Jose
scale.

The heavy infestation of the green citrus aphid in Florida, re-
ported in the last number of the Survey Bulletin, was brought under al-
most complete control by a period of heavy rains during the first part
of the month, which encouraged a ramoid development of a fungous disease.

The tomato pinworm was unusually abundant in southern California.

During the last week in the month Mexican bean beetles were ob-
served in the field in the Norfolk section of Virginia. During about
the same period they were reported from Alabama andMississippi.

Damage to beans by the bean leaf beetle was reported from Georgia
to Louisiana and up the Atlantic coast to Virginia.

A light infestation of pepper weevil was found in Sarasota County,
Fla. This is'the first infestation in the State outside of Manatee
County.

The tobacco flea beetle was more destructive than usual in the Caro-
linas. It was also reported in small numbers from Florida and Tennessee.

In the eastern part of the Cotton Belt, although boll weevils ap-
parently passed the winter successfully, the small numbers that went into
hibernation indicate light early infestation. In the southern part of
Texas, on the other hand, owing to the fact that the cotton remained green
throughout the winter, the insect will probably be more abundant than
usual.

Present indications are that the cotton flea hopper will be more
abundant than usual in parts of Texas. The spring emergence is higher
than in any previous year.

GENERAL FEEDERS


GRASSHCOFPFERS (Acrididae)

Indiana. J. J. Davis (April 26): There is every evidence of grasshopper
abundance in the western tiers of counties and in northern Indiana,
with scattered outbreaks more or less general in the northern half of
the State.

Illinois. W. P. Flint (April 26): The weather has been very cool and wet
during the month of April. Grasshopper eggs brought into the labora-
tory are now hatching in about 12 days after being brought in. No
hatch outside has been observed.

Missouri. L. Haseman (April 27): Grasshopper eggs are coming through the
winter in good shape, with perhaps not over 5-percent mortality of eggs.
With a statewide abundance of e,:rcs, as shown by winter surveys, there
are prospects of a heavy hatch of young hoppers throughout the State
during May.

Nebraska. M. H. Swenk (April 22): Grasshoppers of various fall-hatching
species were reported present in alfalfa and other fields during March
and April; however, no Melanopli had hatched up to April 20.

Kansas. H. R. Bryson (April): E. G. Kelly reports that grasshopper e@7-s
were abuiindant in alfalfa, and clover fields in southeastern Kansas on
April 17. Hoppers recently hatched were observed at Manhattan on
April 19. Eg-s are abundant in experimental plots at Manhattan.

Oklahoma. F. A. Fenton (April 17): A recent trip was made in the north-
central part of the State with R. E. Shotwcll. Eggs of ",_lanoplus
differentialis Thos. were found to be in .,roodi condition, and Mr.
Sh.-1t 'ell siimated the date of hitching as approximately the middle
of I.:.''.y,

Montana. H. 3. I.UIlls (April 22): First reports of graschoppers hatching
were from Powder River County in southeastern Montana on April 21.

Utah. G. F. Kno,:wlton (April 17): Me.lanoplus sp. is ju2t beginning to
hatch on warm south slopes at Genola, Utah County. A late season has
delaye,-d grasshopper hatching. y-":.,. of Hildeman's locust (Hippiscus
corallipes Hald.) are about half-, rr-.-nr, in the same county.

MC..;. CRIC.T (Anabrus si vro! : Hald.)

Montana. H. B. Mills (April 22): Mormon crickets bogafn hatching in Y,:llo-
stone and Big Horn Counties in south-centr.l Montanr and in Lake County
in west-central Montana about April 12, and t:., are now lar :%ly
hatched in the lower areas.








-72-


Colorado. C, R. Jones (April 23): The County Agent in Moffat County informs
us that the Mormon cricket on the Western Slope is hatching profusely.

Idaho. C. Wakeland (April 19): In north-central Idaho Mormon crickets began
hatching in Idaho County about March 15, in southwestern Idaho in Ada
County about March 25, in Elmore County about April 1, and in Washington
County about April 5. These are the earliest counties in the State
infested with Mormon crickets. Continued rainy, snowy, cold weather is
.delaying activities of these insects.

Utah. C. J. Sorenson (April 26): Mormon crickets now in third and fourth
instars menacing farm crops in Juab, Millard, and Tooele Counties,
central Utah, Crickets are already mich more numerous than in 1936.
Hatching has not yet taken place on high mountainous elevations where
many eggs were deposited and where many are still covered by snow.

Nevada, G. G. Schweis (April 21): A member of this department made an
investigation of the Mormon cricket in eastern Nevada during the last
few days and reports great numbers of crickets throughout the area.

WIREWORMS (Limonius spp.)

Idaho. R. W. Haegele (April 19): Adults of wireworms, L. californicus
Mann., are emerging and large numbers were occasionally observed at
Parma, southwestern Idaho.

Washington, E. W. Jones (April 19): The Pacific Coast wireworm (L. canus
Lee.), the sugar beet wireworm (L. californicus), and the western
field wireworm (L. infuscatus Mots), were attacking young onion and
carrot plants generally during April at Walla Walla, in southeastern
Washington.

MAY BEETLES (Phyllothaga spp.)

Mississippi. J. Milton (April 24): May beetles are injuring roses and
young pecan trees in Jackson.

E. W. Dunnam (April 18): On April 16 the first beetle
observed this season was at a light in Leland and on April l1 two more
were noted.

Louisiana. H. L. Dozier (April 23): The first spring flight took place on
March 20 near Sunset, where the beetles were fairly abundant during
several nights;. They were very abundant there on April 23. The beetles
were observed in vast numbers at lights at Opelousas on April 10-12.

Iowa. H. E. Jacques (April 22): May beetles are being taken at lights and
in soil activities, but hove not yet shown up in large numbers.







-73-


Kansas. H. R. r'-yson (April 2?): WThite grubs are moderately abundant at
Manhattan this spring. Adults have not been- taken at 17hz but are
near the surface of the soil ready to fly when the soil becomes warmer.

Oklahoma. F. A. Fenton (April l1): The first activities of June beetles
were reported on April l14.

Texas. F. L. Thomas (April 26): The following record: 'yere made on species
active since April 18: P. calceata Lec., P. hirtiventris Horn, P.
rubiginosa Lee., P. crassis sima Blanch. abundant at Cclleoe Station,
Brazes County; P. praetermissa Horn, P. tristis F., P. cong:rua Lee.,
active but not abundant at College Station; P. calce.ta, P. mi cans Knoch,
P. crassissima, P. arkonsr:na Schiffr., abu-nant in Sr.mith County; P.
prunina Lee., P. profunda Blanch., P. bipartita Horn, P. praeteris a,
P. tristis, active but not abund-.Ant in Smith C'ounty; ni P. sutricia
Lec., active on April 2o in Zavalla County at Crystal City.

GP7EE: JLI., r LE (Coti ris nitidr, L.)

Kentucky. 1. L. Didlake (April 23): Green June bee-tle larvae excessively
abundant in pasture and potato field near Louisville.

Tennessee. L. B. Sc -tt (A;pril 5)'. P..ort from Sumner, Smith, and Davidson
Counties in north-centrIal Tnnessee. indicated v severe, dma.-e in tobacco
plant beds by grecn June beetle.

CUTT7RMS (Noctuict'e)

Florida. F. S. Chamberlin (April 23): The wirm, -,ot weather in J',nuary
favored the growth of green vegetation on tobacco land at %uincy,
Gadsden County. For this reason, it was probable th'-t cutwo'r infesta-
tion on newly sot tobacco plants this snrin,- would be heavier than
usual. Observations made during the latter part of Ap'ril indicate, how-
ever, that the infostati'ns arc only slightly i-reat-r than normal.

Indiana. J. J. Davis (April 26): Climbin!- cutwcrms are be,^innin, to show
some activity in the northern end cf thc State, quite destructive in recent years. Observations indicate that they
are less abundant than last ye',r, but still sufficiently nur.orous to
require active control in orchards.

Michigan. R. Hutson (April 22): Cutworm activity bec-une noticeable carly.
Reports of injury to fruit trses have been received from 7 !rrien County.

Tvnn.isue. L. B. Scott (April l1): Cutw porms, probably of FYltia ducens
Walk., are abundant in timot'.-:' and bluegrass pasture's *t Ci:.rksvill'-,
Montgormery Cr unty.

Alab'ma. J. M. Robinson (April 22): Cutw rms are active e in --dnts at
Auburn, particularly .wbre tomato plants have ben tr2nsl'nmtud.









Missouri. L. Haseman (April 27): Early indications are that cutworm popu-
lations in central Missouri will probably be below normal, though inthe
last week they have been showing up in greater numbers. "Practically no
gardening work has been done.

Kansas. H. R. Bryson (April 20): R. C. Smith and R. Hi. Painter found a
large number of dingy cutworms (F. subgothica Haw.) in'alfalfa and wheat
fields, but they were not doing any damage.

Utah. C. J. Sorenson (April 26): Pale western cutworm (Porosagrotis
orthogonia Morr.) causing slight injury in dry-farm grain in the north-
western part of Utah County and on the Levan ridge in Juab County.

Washington. R. S. Lehman (April 19): Chorizagrotis agrestis Grote, has
been doing considerable damage to cabbage plants in southeastern Wash-
ing&ton. The plants are greenhouse-grown and were set out this spring.

California. J. Wilcox (April 1)4): From one to four cutworms were found per
tomato plant in fields examined in Orange County. They were doing con-
siderable damage to leaves and blossoms. Species determined by S. E.
Crumb as F. annexa Treit. and Lycophotia margaritesa saucia Hbn.

FALL ARMYWORM (Laphygma frugiperda S. & A.)

Louisiana. L. 0. Ellisor (April): A serious outbreak'of the fall armyworm
on oats occurred in northern Louisiana during the last 2 ieeks. They
are heavily.parasitized and their numbers are being reduced rapidly.

C. L. Straconer (April): An outbreak of the fall armyworm, or
grass worm, occurred on sugarcane in southern Louisiana, but the larvae
were heavily parasitized and are not expected to do much damage.

;TITE-LI7D SPHINX (Sphinx lineata F.)

California. S. Lockwood (Aoril 20): An outbreak of the white-lined sphinx
has been reported to this office from Riverside County. Apparently it
is destroying native vegetation in and around Palm Springs, Riverside
County.

PAINTED LADY (Cynthia cardui L.)

Vermont. H. L. Bailey (April 27): A specimen of the painted lady butterfly
was noted at Montpelier, central Vermont, on April 10.

MOURNIDG-CLOAK BUTTERFLY (H.madrynos antiopa L.)

Ohio. J. S. Houser (April 5): An adult was observed flying in a woodland
in Moorland, Wayne County, in north-central Ohio.

Utah. G. F. Knowlton (April 14): Mourning-cloak butterflies have been
observed in flight for the last 3 weeks, whenever the weather was warm.

CEREAL AND FORAGE- C R OP I N SE CT S

T.EAT A11D OTHER -'.LL GRAYS

{ZSSIA-; FLY (Phytophaga destructor Say)

Ohio. T. H. Parks (Aoril 24): The hessian fly infestation is very low and
no visible damage is expected in any part of the State.

Indiana. W. B. INoble (April 19): Spring emergence of the hessiin fly is late.
A dissection of overwintered. puparia from volunteer wheat at Lafayette
showed 35 percent to contain white to pink pupae. Very few eggs present
on young wheat. (April 23): A dissection by H. R. Painter showed 63 per-
cent of pu-oaria from volunteer wheat n.ear Lafayette to contain white to
redpupae. About 3 percent showed emergence of adults.

Illinois. C. Benton (April 15): White to red pupae present in volunteer
wheat in Christian County, central Illinois.

Missouri. L. Haseman (April 27): Except for a few areas, the h-ssian fly isnot
particularly alarming this s-orin.. The- worst center, according t- our
observations, is on the east side of the State, particularly in the
northeast part, where some heavily infected fields have been found.

Kansas. H. R. Bryson (April 22): 'Wheat fields in the western part of the
State are practically free of infestation. In one field near Junction
City adults were laying eggs.

Cir'". U"_- (Blissus leucooterus Say)

Ohio. T. H. Parks (Ap;ril 24): A survey made in eight counties from April 20
to 23 showed chinch bugs abundant in clumps of volunteer timothy in many
localities. The heaviest infestation was found in y ,.!rot County, north-
central Ohio, though this may not be the center of the infestation.
Counts revealed from none to 206 ovcrw'ntering bugs rpr square foot of timo-
thy clump, depending on the locations visited. The average number per
square foot for 43 examinations is 25 bu.s. This is 12 times as many as
were found in a similar survey during the spring of 1936. Dry weather
will undoubtedly bring trouble.

Indiana. J. J. Davis (Aoril 26): Chinch bug abundance is .nticipatd along
the western border of the State from Lake County to G-reene County and
exter.din.- into the interior for at least two tiers of c-unties.

Illinois. C. Benton (Anril 17): The weather has been cold, except during the
past few days, when maxirnims hav-e r1ched 76--8S F. Observ:itions near
Taylorville, Christian County, in central Illinois, on these days showed
the '.u;-- to be restless and numbers movin; around :amon, the bunch- r .:s
clumps, but most of thcrn still rather ina:ctively hiding in the clumps.
There may h-ive been some migration on these days, notwithst-i.91.- the
rather stiff wind prevailing, although casual observations in sn2ll
grains have shown no bugs yet.
LIBRARY
STATF Pl .,, W )ARD










W. P. Flint (April 22): The cold, wet weather has held the
chinch bugs in hibernation. A very few flew out on April 22, but the
number leaving winter quarters was very small.

Missouri. L. Haseman (April 27): In some areas the winter mortality of
chinch bugs seems rather high, but generally the carry-over has been
about normal. Only in three or four restricted -areas does the pest
appear to be especially alarming, though normal or perhaps above-normal
carry-over has been observed throughout most of the farming counties of
the State. West-central, northwest, and north-central areas include
some localities with alarming carry-over.

Nebraska. 1. H. Swenk (April 22): A survey of the winter survival of the
chinch bug in the center of the more heavily infested area in south-
eastern Nebraska, including Otoe, Nemaha, and Johnson .Counties, during
the latter p-art of March showed thnt slightly more than 80 percent of
the bugs wintering in the bluestem bunch grasses had survived. Other
infested counties include Richardson, Pawnee, Gage, Lancaster, Cass,
and Sarpy.

Kansas. H. R. Bryson (April 17): 'A considerable number of chinch bugs over-
wintered successfully at Manhattan during the last winter. They are
late coming out of winter quarters. E. G. Kelly reports that they were
not out of hibernation in the southeastern Kansas counties on April 10.

Oklahoma. F. A. Fenton (April 17): An examination of the fields in Payne
County, north-central Oklahoma, shows the chinch bug to be present only
in small numbers and not sufficient to cause trouble this season. The
averages per square foot for the last 2 years are as follows: 1936--
Sorghum 2, grass 14; 1937--sorghum 13.8, grass 14.g.

GRC-PAIN APHIDS (Aphiidae)

North Carolina. Z. P. Metcalf (April. 14): The green bug (Toxoptera graminum
Rond.) is more abundant on oats and other small grains, in the Upper
Piedmont and mountain counties than for the past 10 years. The pest has
been determined as the green bug, although several other species are
undoubtedly involved.

Maryland. E. N. Cory (April 23): Grain aphids, probably Macrosiphum gran-
arium Kby., attacking wheat on the Eastern Shore in Tra-pe, Talbot.County,
and Ridgely, Caroline County. To specimens received.

Kansas. H. R. Bryson (April 17): No reports or observations on infestations
of the green bu- have been noted by E. G. Kelly, extension entomologist.
Samples of wheat brought in for examination for mite injury contained a
few green bugs.

Oklahoma. F. A. Fenton (Aoril 17): An incipient outbreak of the green bug
develo-ed in the southwestern part of tht' State in Caddo, Xiowa, Comanche,
Tillman, and Cotton Counties. Fields were visited on March 31 and on
April 1 and 2, and numerous dead spots in many fields were found due to
the activities of this pest. In some cases there has been no apparent








-77-


increase from last winter, and in others the infestation was lifht. In
all cases the insects were breeding in both volunteer and drill wheat.
The p-arasite Lysiphlebus testacipcixs Cress, is rresent. A s;conr tripT
to the infested section was mnede on April V0 and the insect had co,-
pletely disappeared from most of the fields.

Colorado. C. R. Jones (April 23): P.eports have been received that the ir.in
aphid is prevalent in the wheat fields in Las Animas County, near Moehne.
A few fields of winter wheat show a d.-o:,e f abo-it 25 percent; ho, ver,
considerable numbers of ladybird beetles are now working on the grain
aphid.
SAY'S PLA.T BUG (Chlorochroa soyi Stal)

California. C. S. Morley (Aoril 2): Say's plant b wis wer,- fund in heads of
barley in Kern County at the rate of one to five bugs p fr five sweer of
the net. They were most numerous at the edAges of fi--lds cl',nted to
cotton last year.
SA FLiES (Tenthrodinidae)

Pennsylvania. E. J. Udine: As the wheat stem sawfly (Oeohus r, c L.)
h.s -pr.ad into eastern Penns!ylvania, it has grad':'N]y driven out the
black rr-iin stem sawfly, Trachelus tabidus F, which has been estab-
lished for many years in that part of the coivntry. The history orf its
spread shows that in 1)19 it was confined to Ne; York St',te, while T.
tabidus occurred abundantly in Pennsylvania. By Y125 a mixtur off the
two species wvas found in certain sections of Pennsylv-,.nia along the
Susquehenna Valley, with a prc.:ond'rance of T. tnobidus in evidence. By
1927 parts of the Susquehanna Valley in Pennwfylv-'-nia showed an' cvn
r-ib.4ince of both species, and by 1936 most of the eastern Pennsylvania
and r,".rts of the Susqueh.nrna Valley re iornwre infcst;d preponder'.ntly
by C. pygmaeus, with the other speciLus rarely showing uo. trbldus,
on the other hand, has been steadily advrncinc- to the south and west,
where no wheat ".wflies o)rigin-lly occurred, and was fund last year for
the first time in Pittsylvania County in southern Vi"-rinia.

Kansas. H. R. Bryron (April 22): R. H. Painter and R. C. Smith found saw-
fly larvo.,e plentiful on wheat. Lx'.-' u are leaf feeders but 'vere doing
.'pr- rent injury to w.-. t-

FALSE '.:**... (Eleodes si,.)
Nebraska. M. IF. Swenk (April 22): Reoerts of severe damage to winter wheat
by the plains false wire.7or.i (E. opaca Say) .oere received in Airil from
Saline, Snerirmasn, Kearnrey, and urnas Couonties. One re-r irt from eastern
urnas County stated that in some fields 90 perce-at of the -"he-t plants
had been killed durir,' the winter and spring. Another rEroIrt front te
southern part of the county indicated that in some fields 70 percent of
the wheat had been kilic The SDlin" County corrcs- ondunt ,Trote th'rt
these false wireworms were very num:'rous about th;. roots of wint er wheat
in two fields. In Shermran County the pTest was ai : ..,t duri-- tie f ,ll,
winter, and sprint in cornfields around Ansle,.








-78-


Kansas. H. R. Bryson (April 20): False wireworms (Eleodes spp.) were quite
numerous in western Kansas last fall and are still present in consider-
able numbers. Very little damage'was done to planted wheat, owing to
the fact, that sufficient soilmoisture was present to insure rapid
germination. One report was received from Atwood, indicating that
larvae had done some injury to the underground part of the wheat stems.

CLOVER MITE (Bryobia praetiosa Koch)

Oklahoma. F. A. Fenton (April 17): A new pest, which has caused consider-
able injury in many wheat fields, is developing. This has been tenta-
tively identified as the brown mite (B. praetiosa). It was first seen
in the southwestern part of the State but has been reported recently
from Enid to Stillwater, in the north-central part of the State.

A MITE (Petrobia tritici Ewing)

Kansas. H. R. Bryson (April 22): R. H. Painter and R. C. Smith found a mite,
probably.P. tritici, in four fields in central Kansas in the vicinity of
Ellsworth, McPherson, and Lindsborg, but it was not causing the damage
reported. Dry weather was responsible for most of the injury observed.
Mites wereabundant in only one field.

CORN

EUROPEAN CORN BORER (Pyrausta nubilalis Hbn.)

Virginia. H. G. Walker and L. D. Anderson (April 27): Pupae were found at
Norfolk on April g. Several of the pupae were getting quite dark in
color, as though they had been in the pupal stage for several days.

ALFALFA

ALFALFA WEEVIL (Hpera posticar Gyll.)

Utah. G. F. Knowlton (April 14): Alfalfa weevils have been picked up on a
number of occasions this spring, in berry patches many rods from the
nearest alfalfa field.

California. A. E. Michelbacher (April 21): The harvest of the first crop
of alfalfa in middle lowland California is nearly completed. In not a
single case did the alfalfa weevil cause any economic injury. In one
field near Patterson, in the San Joaquiiin Valley, the larval count
reached about 2,000 individuals per 100 sweeps of an insect net before
the field was cut. In the rest of the infested area highest average
collections oper 100 sweeps of a net failed to reach 500, In many fields
the count was less than- 100. Parasitization by Bathyplectes curculionis
Thorns. has continued heavy. In the San Francisco Bay area it has
remained close to 95 percent. On the 29th of March in the heavily in-
fested field near Patterson only 31,5 percent of the larvae were para-
sitized, while in other fields in the San Joaquin Valley parasitization
ranged from 70 to 9O percent.

PEA APHID (Illinoia piXi Kltb.)

Virtinia. L. 7w. -r'n.ron (April 27): I have ju-st nade 100 swee-oins in alfal-
fa on the experiment station farm and collected anrroximratrly 1/2 oint
of aphids, which I estimate at 50,000 or more. S',eepin'rs made in this
same field on April 30, 1936, resulted in an estimated collection of
15,800 a)hids per 100 sweepings. Sweepir,.-; were also made on pneas grow-
ing on thile city farm nearby. Approximately 1,000 aphids were collected
per 100 sweeps. On April 30, 1936, swepr-r made in a field of reas on
this same farm,resulted in the collection of 35 aphids rer 150 s-ecps.
The peas on this farm, on which the sweeings .ere made, a- -::.-" to be in
full bloom now. In view of these findings, it appears that the pea a-hid
is considerably more abundant in the Norfolk area than at this time last
year.

Louisiana. C. 0. Eddy (Aoril): The -ea aphid has been numerous a number of
times but has not been consistently injurious.

Kansas. H. R. Bryson (April 20): R. C. Smith found oea arhids in every alfal-
fa field examined from Manhattan westward to the central ,oart of th State.

Utah. G. F. Knowlton (April 20): Pea aphids have been hatching in small
numbers in Utah and Salt Lake Counties. The sprin. has been unusually
late, retarding development. At Hy.d. Park rea anhids have hatched out,
and are rather ubundint on sweet clover. Lost of those exairined were in
the second and third instars. They are less abundant unon alfalfa.

CLOVER

CLOVER LEAF 7TELVIL (Hypera punctata F.)

Kentucky. M. L. Didlake (April 23): Clover leaf weevil larvae are numerous
in red clover, also in tobacco plant teds, and are injuring lettuce and
cabbage at Owenton and Carlisle.

Kansas. H. R. Bryson (April 20): R. C. Smith rrrorts the clover leaf weevil
numerous at M[anhattan. ITe found no weevils in the alfalfa fields exam-
ined en route in a recent trip to the central r-.'t of the State.

CLOCVE?. STEM ]C'FR (I- ..,mc zardi Latr.)

adults rapidly -- ,J is laying e, .3 abundantly in souiith Lui.siana.










FRU I T INSECTS


APPLE

APPLE APHIDS (Aphiidae)

Massachusetts. A. I. Bourne (April 26): Orchard plant lice are normally
abundant, as evidenced by overwintering egs. We found the first
hatching at Amherst on April 16.

Connecticut. P. Garman (April 20): Aphis pomi Deg. and Anuraphis roses
Baker are less abundant than last year in New Haven County. Lady-
beetles emerging in considerable numbers from hibernation.

New York. N. Y. State Coll. Agr. News Letter (April): The rosy apple aphid
was hatching generally in the Hudson River Valley the last week of the
month. A few grain aphids (Rhopalosiphum prunifoliae Fitch) and green
aphids were also observed. In western New York a very few specimens of
the grain and green species had been observed by the last of the month.
The only report of the rosy aphid was made from Ithaca, where a single
specimen was taken on April 26.

Pennsylvania. J. 0. Pepper (April 26): Infestations of rosy apple aphid
are scattered in eastern Pennsylvania apple orchards.

New Jersey. E. Kostal (April 22): Rosy apple aphid infestation light on
apple trees at Morganville, Monmouth County, where the trees are in
pre-pink stage.

Virginia, A. M. Woodside (March 30): Apple aphids began hatching in Augusta
County (central valley region of Virginia) about March 30. Rosy aphid
rare.

W. S. Hough (April 21): Apple aphids not numerous. Little or no
commercial damage expected around Winchester, in northern Virginia,from
rosy aphid.

Indipna. J. J. Davis (April 26): Apple aphids are scarce in southern
Inrianr-., according to G. E. Marshall.

Wisconsin. C. L. Fluke (April 20): Eggs of the common species of fruit
aphids not abundant, suggesting a very light early infestation in south-
western Wisconsin.

Missouri. L. Haseman (A'oril 27): The different species of plant lice on
fruit trees seem to be less abundant this spring than normally. Only
one or two reports have been received.











CODLING MOTH (Caryocarsa pomonella L.)

Georgia. C. H. Alden (April 21): First codling moth c'-:>.'t in the bait
trars eat Cornelia, northeastern Georgia, onr. April 16, about the same
time as in 1936. Caught 42 moths in 12 traps on Arril 19.

Ohio. T. H. Parks (April 24): n.amrrition of overwintering cocoons indicates
a high winter survival. Birds have destroyed many, making; it difficult
to collect larvae from tree trunks.

Indiana. L. F. Steiner (April 20): The first r-uoation was noted by S. A.
Sumnmerland on April 6 at Elberfeld (extreme southwestern Indiana. On
April 20 approximately 25 percent had oupated, as compared to 50 percent
on April 16, 193G. At Bicknell (50 miles north of Elborfeld) only 4 per-
cent h. pup-ated. on April 16. The current population is well above
normal. Winter mortality was very low and a heavy flight of the spring
brood is anticipated.

J. J. Dvis (Anril 26): The codling moth is overlvintering in
greater numbers than usual. G. E. Marshall r-ports th.:t 3 porcunt of
the worms under bands had pupated by April 22 at Orleans.

Illinois. W. P. Flint (Apiril 19): Codling moth pusation was general in
southern Illinois during the week beginning April 19.

Missouri. L. Haseman (April 27): For the past week codling moths hrve been
pupating in the southern part of the State and are exected to bein
emer:,in:- any day here in central and northern :'issouri. The last 5 or
6 cold, rainy days and nights have "in slowed down moth dev1o' :.t,
as well as fruit development.

Kansas. H. R. Bryson (April 22): R. L. Parker reports a normal carry-over
of codling moth in northeast rn Kansas.

EASTERN TrLET CATERPILLAR (F.)losma anricana F. )

New Hampshire. J. C-. Conklin (April 2): The eastern tent caterpillar was
observed hatching in southern -'Tw Ianrshirf on April 19. On April 22 a
heavy windstorm, accompanied by snow and sleet, occurred r many of the
newly hatched caterpillars were destroyed.

Vermont. H. L. Bailey (April 23): First hatchi:- .- of the eastern tent cat r-
pillar was observed at Brattleboro, in the southern corner of the State,
on April 23. EF- masses moderately ;.' i..

MasZOchusetts. A. I. Bourne. (April 19-2'.): ; js were found to be hatching
by the 19th in some sections. -: .east is still very abundant over the
State.






-("2-


Rhode Island. A. E. Sten2 (April 29): We have noticed quite a number of
tent caterpillar ,ebs; apparently a high percentage of the eggs are
hatchin..

Connecticut. P. Garman (April 20): Egg masses of the tent caterpillar much
less abundant than during the last 3 or 4 years. Eggs have now hatched
in some localities in New Haven County.

E. P. Felt (April 24): Apple tent. caterpillars are present in
small numbers locally in southwestern Connecticut.

New York. R. E. Horsey (April 17): Hundreds of egg masses of the eastern
tent caterpillar noted in territory south of Rochester and in the city
nearby, where they were severe last year. Often a dozen or more egg
masses are found on one tree. A large number were found on an orna-
mental planting of crabapples that had the nestsremoved and the cater-
pillars destroyed last spring and summer, wherever found. No defolia-
tion was noticeable here last fall, but evidently enough caterpillars
escaped to mature a number of moths.

E. P. Felt (April 24): Apple tent caterpillars are present in
small numbers here and there in southeastern New York.

M. Kisliuk (April 26): Larvae 1/4 inch long were found in the
tents on wild cherry on April 25 at Alley Pond Park and Cunningham Park,
Long Island. There were also some unhatched eggs. These insects appear
to be less abundant than in 1936.

Pennsylvania. H. N. Worthley (April 21): Egg masses first observed hatching
on April 19 at State College, Centre County, in advance of the delayed
dormant application to apple.

J. 0. Pepper (April 26): Egg clusters do not seem as abundant
as last year in eastern Pennsylv-ni2. First hatching of eggs April 12.

E. J. Udine (April 13): Eggs were hatching on April 13 at
Carlisle, Cumberland County. Last year in some locations e~gs hatched
on April 5.

New Jersey. E. Kostal (April 22): Infestations on apple and wild cherry
trees at Morganville, Monmouth County, are very moderate, as compared
with last 3 years; first larvae noted on April 22, as compared with
April 4, in 1936.

South Carolina. C. 0. Bare (April 12): An outbreak of the eastern tent
caterpillar in Charleston County during the past 2 weeks attracts con-
siderable attention. Nearly all wild cherry trees have been kept
defoliated ,almost entirely, and the tents are frequently on wild plum.

Georgia. 0. I. Sn,.pp (M-irch 29): The first colonies of the season were
observed on wild cherry at Fort Va.lley (central part of the State) on
March 29. The infestation appears to be lighter than usual.










T. L. Bissell (April 3): Tents of M. americana are present in wild
cherry at Griffin, central Georgia, with larvae about one-quarter crown.
(AT ril ?6): Tent caterpillars are unusually abundant on wild cher-y,
crabapple, and other fruit trees, and are also found wandering in fields
at Ex-neriment, in central Georgia, and at Elberton, in north'asr-ern
Georgia.

Florida. A. HI. Madden (March i6): A number of full-F-rown l.arv e observed
at Quincy, Gadsden County, crawling about in search of places to puTatc.
Apparently not sufficiently abundant to cause appreciale d ., -e.

Tennessee. L. B. Scott (April I)-): Many webs of tent caterpillars noticed
on wild cherry at Clarksville.

Mississippi. D. W. Grimes (Anril 2):; Numerous colonies on peach trees in
vicinityr of Durant, west-centr-l nart of State.

E':E-SPCTiP-'7DYQOTH (Spilonota ocellana D. & S.)

New York. IT. Y. St. Coll. Arr. ;-.0ws Letter (Anril 12): In western ITew York
the budmoth is general, but serious only in a compratively few blocks
in Ni>gara County. :Timerou- in many orchards in Orleans County.

FLATT3ADED APPLE TREE BC? "F. (Chjsobothr i feorata Oliv.)

North Carolina. Z. P. Metcalf (April 14): Some cases of very serious d'n3.me
by the flatheaded apple tree borer h.ve been. reported from Anyon County,
near the central part of the southern boundary.

Kansas. H. R. Bryson (April 19): -.unmrous reports of trees infe;;tid with
the flatheaded apple tree borer have been received. The infj:stat ions
are more numerous owing to the low vitality of the trer, curni:d by
the drought during; the last 3 years.

Nebraska. Y. H. Swenk (A-nril 22): Complaints of zever d.c? to fruit and
shade trees by the flathadud apple tree borer continued to be received,
principally from the southeastern r-art of the State, and were concerned
with apple, cherry, and other orchard trees, ai. well as hackberry,
Molin. elm, Amvric.'n elm, ;-.iple and other shadc trees.

Oklahoma. T. A. Penton (Arril 17): R-norts have been received from widely
sern.rated parts of the State of injury to orchard and shade trees from
the flath-.oded a'op]s tr'-e borer.

APPLE 77-EA WEEVIL (Orchestes pallicornis Spy)

Ohio. T. H. P.rks (April 2)4): Adul.ts were irst observed feedin, on the
young pole folia:le on A;ril 25. Ve.r-y few had left their hibernation
quarters under the tree at that time.










SAN JOSE SCALE (Aspidiotus perniciosus Comst.)

Vermont. H. L. Bailey (April 23): Scattering on apple and plum trees at
Brattleboro. Many apparently live insects.

New York. R. E. Horsey (April 17): Scarce at Rochester since the cold win-
ter of 1933-34. Some scale lived over at the base of shrubs where they
were protected by leaves or snow. This year the scale was found on
several cotoneasters, a few being severely infested. Several Prunus
spp., all low shrubs, have considerable scale. Four mountain ash trees,
6 to 8 inches in diameter, were a few years ago matted with scale in
places on the main trunk, but there is only a little scattered new scale
to be found this year.

E. P. Felt (April 24): Very-abundant on apple at Jericho, N. Y.

New Jersey. T. L. Guyton (April 5): Nurrerous and causing death of some
limbs and trees at Pittsgrove.

Michigan. R. Hutson (April 22): The survey conducted in southern Michigan
in Berrien, Allegan, Grand Traverse, Oakland, and other fruit-producing
counties, as well as casual observation in other counties where fruit
trees are not so numerous, indicates that very few scale survived the
winter. The populations are low in all orchards visited.

Wisconsin. E. L. Chambers (April 24): Scale apparently survived the winter
in southern and eastern Wisconsin better than usual because of the mild
winter and no low temperature over extended periods, All susceptible
host plants in Appleton were sprayed.

North Dakota. J. A. Munro (April 22): One cotoneaster hedge in the northern
part of Fargo is heavily infested with San Jose scale.

Georgia. 0. I. Snapp (April 20): Infestation has increased rapidly as a
result of the uninterrupted reproduction during the unusually mild win-
ter, and the pest is now a serious problem in a number of peach orchards
in central Georgia. The infestation is now considerably heavier than
-sual.

Mississi-pi. C. Lyle (April 24): The mild winter has been favorable for
increasing infestations. Most plant bcard inspectors reported that it
was causing very serious injury in nearly all sections of the State.

Missouri. L. Haseman (April 27): The carry-over in Missouri has been very
light this year and comparatively little late dormant spraying has been
done.

California. L. D. Christenson (April 23): Within the past 2 weeks we have
noted an infestation in an orchard at Hemet.






-85-


EUROPEAN RED MITE (Paratetranychus pilosus C. & F.)

Massachusetts. A. I. Bourne (An-oril 26): For the first time since this red
mite established itself in the State there is a very general scarcity of
the p.;st. In some orchards the growers have found practically no viable
ej7s; therefore they are omitting the customary oil sprays. I have found
no orchard, in which there is a heavy infestation.

Connecticut. P. Garman (April 20): Eggs much less abundant than usual.

Michigan. R. Hutson (Arril 2?): E,-s are scattered in most places, although
they are numerous here and there on especially susceptible varieties of
trees.
cYSTSI.SiiELL SCALE (Lepidosaphes ulmi L.)

Michigan. R. Hutson (April 22): Infestation from -raverse City, Parma, Sagi-
naw,.Grand Rapids, and vicinity have been reported on fruit trees.

Wisconsin. E. L. Ch:,-mbjers (April 24): Oystershell scale on both lilac and
apple seems to be on the increase, with very little reduction as a result
of winter temperatures.

SCURFY SCALE (Chionasois furfura Fitch)

New York. E. P. Felt (April 24): Exttr-!ily abundant on apple trees near
Westbury, L. I.
Pennsylvania. J. 0. Pepper (April -26): Abundant in a ,few apple orchards in
Adams County, on the southern boundary, just east of the central part.



FLU CURCULIO (Conotrachelus nenuphar Hbst.)

Virginia. A. 1M. Woodside (April 17): No plum curculios emerging from hiber-
nation in Augiusta County (central valley).

Georgia. 0. I. Snapp (April ?1): The ape carance of ,dults from hibernation
at Fort Valley (centr',l Georgia) is still consid rably loss th'-r. uzu-l,
and the indications are that the inf.sta.tion this year will be lighter
than average. A number appeared on peach trees near favored places of
hibernation during the periods March ?3-26 and r'ch 21-A)rmil 3, but the
cool weather prevented them from becomr.ing disseminated thr' ui.out the
orchards until April 21, when a few were found on trees in the orchards
some distance away. Temperatures in the 90's during the period April 17-
21 apparently caused this activity; nevertheless, most adults are still
confined to outside rows of peach trues. TThe fir-t C. nem-iphnr : of
the season was found in a gre.-n each on Aporil 7, and the first larva
(not more than 4g hours old) '7as found in a green peach on A,-ril 20. On
account of the cool weather in March and April delaying activity of the
plum curculio, it is doubtful whether there will be a second en'ration
here this year.









T. L. Bissell (April): One curculio was jarred from wild plum on
Anril 10 at E'-eriment, in central Georgia, the first of the season. We
have been jarring peach and wild plum since the first of March. On
April 26 curculios were numerous on peach.

C. H. Alden (April 15): Have been jarring peach trees at Cornelia,
in northeastern Georgia, since March 20, but no adults were found until
April 13, when 4 were caught on 24 trees. On April 15 caught 23 on 24
trees. The emergence from hibernation is taking place long after full
bloom (March 20 to 25) this year, as at this time the shucks are being
shed from the peaches in this section.

ORIENTAL FRUIT MOTH (Grapholitha molesta Busck)

Georgia. 0. I. Snapp (April 21): There has been no peach-twig injury from
this insect to date at Fort Valley (central Georgia), and first-brood
larvae have not yet begun to appear. The first larvae (about 3 days old)
of the first brood were found in peach twigs last year on April 16.

Ohio. R. B. Neiswander (April 7): Hibernating larvae were abundant on quince
trees in Ottawa County. Scales of bark and crevices yielded as many as
63 living larvae on 1 tree. This condition existed in spite of the fact
that birds had taken a considerable number and that approximately 30 per-
cent died during the winter.

PEACH BORERS (Conopia spp.)

Idaho. R. W. Haegole (April 7): A report on this borer appeared on page 13
of the March 1 issue of the Bulletin. The infestation was first observed
in 1936. The trees where this borer was working in the trunk and crotches
usually had a heavy infestation of the peach borer (C. exitiosa Say)
working at the ground level and below. The infested area was examined
on April 7 and all borers found in the trunks or crotches were dead,
while the borers below the ground level or the snow line were alive. Min-
imum temperatures in this area in January ranged from -15 to -20 F.

LESSER PEACH BORE. (Synanthedon pictipes G. & R.)

Michigan. R. Hutson (April 22): Lesser peach borer is numerous in the vi-
ainities of Port Huron, Shelby, and Hillsdale.

BLACK PEACH APHID (Anuraphis persicae-niger Smith)

North Carolina. Z. P. Metcalf (April l14): The black peach aphid has been
reported from the mountainous section of the State.

South Carolinr. W. C. Nettles (April 29): The black peach aphid is more wide-
spread and destructive than ever experienced throughout the Piedmont sec-
tion of the State, but most especially in Spartanburg County.

Georgia. C. H. Alden (April 20): Attacking peach trees in northern Georgia,
mostly replants, but occasionally on old trees. Killed a few replants










before remedy could be applied. Abunda.nt at Alto, Cornelia, Commerce,
and Esom Hill. More reports of injury from this insect this year than
in any year of the past seventeen.

Mississippi. C. Lyle (April 24): Specimens of this aphid were r ceived from
Hattiesburg on April 21. It was causing serious injury to peach.

California. L. D. Christendon (April 23): During the past two weeks we have
noted a rather severe infestation of black pea.ch aphids in an orchard in
Cherry Valley (near Beaumont).

TA:T I SHED PIAUT UG (Ljg-s pratensis L.)

Virginia. A. M. Woodside (April 17): The tarnished plant bug is rather abun-
dant on peach trees.
PEAR

PEAR PSYLLA (Psyllia pyricola Foerst.)

New Hampshire. J. G. Ccnklin (April 23): On April 19 thq rearpsylla was
very active on pear trees in Durham. The females were ovipositing freely
and it is evident that a rather severe infestation will follow.

New York. 1T. Y. State Coll. Agr. News Letter (April): E of the pear psylla
were first observed in the Hudson Valley about April 7 and by the last of
the month they were abundant in many orchards. In western New York
adults have ap-oeared but few eg-,s have been laid.

CHERRY

BLACK CERY APHID (Myzus cerasi F.)

New York. N. Y. State Coll. Apr. News Letter (April): E;gs of the black
cherry aphid are hatching in the lower Hudson Valley.

RICE WEEVIL (Sitophilus oryzae L.)

North Carolina. 7. A. Thomas (ATril 19): The rice weevil has been observed
frequently within the past few days feEding in the open blossoms of m7ild
cherry.:. At Chadbourn the weevil seems to be feeding on the pollen in
these flowers.
PLUM

TENT CATERPILLARS (1Malacosoma -,.)

California. S. Lockwood (April 20): A tent caterpillar, M. constricta
Stretch, in somewhat more than normal numbers, is infesting prunes in
Sonoma County. The California tent caterpillar (M. californica Pack.)
is rwich more abundant, and some prunes in Sonoma C-unty are almost com-
pletely infested, with from one to seven nests per tree.










GRAPE

GRAPE LEAFHOPPER (Erythroneura comes Say)

Virginia. A. M. Woodside (April 17): On April 16 large numbers of the grape
leafhopper were observed under leaves on the ground in woods. Associated
with them in Augusta County were a few E. obliqua, Say.

Utah. G. F. Knowlton (April l14): Grape leafhoppers have been abundant on
grass in a vineyard south of Ogden for some weeks, Buds on grapes and
Virginia creepers have not yet begun to burst.

California. C. S. Morley (April 2): Overwintering leafhoppers are numerous
under Russian-thistle and other weeds in the Arvin district over half a
mile from the nearest vineyards. Hoppers may be found on the grapevines
in Kern County.

A TREE CRICKET (Oecanthus latipennis Riley)

Ohio. J. S. Houser (April 8): Specimens sent in from Coshocton by a corres-
pondent who had noticed the large punctures in the vine when trimming his
grapes and found the eggs lying parallel to the stem imbedded in the pith.

PECAN

PECAN APHIDS (Aphiidae)

Georgia. T. L. Bissell (April 25): Stem mothers of Monellia costalis Fitch
and Melanocallis caryaefoliae Davis have just matured at Experiment,
central Georgia. They seem rather scarce on pecan.

OBSCURE SCALE (Chrysomphalus obscurus Comst.)

Mississippi. C. Lyle (April 24): A rather general infestation in a pecan
orchard at Yazoo City was observed on March 23 by J. Milton. The scale
has caused noticeable damage. Moderate-to-heavy infestations in pecan
trees on the Delta are reported by D. W. Grimes.

CITRUS

GREEN CITRUS APHID (Aphis spiraecola Patch)

Florida. J. R. Watson (April 21): A. spiraecola increased in March to the
heaviest infestation we have had since 1925 but was brought under almost
complete control by heavy rains the first part of April, which started
a fungus disease. Dry weather for the last 2 weeks has somewhat checked
this disease but aphids are still comparatively scarce. The aphid-
eating ladybeetle Lois sp. has been established in two additional
counties, Brf.vard andT Highlands.






-g9-


C07'.?A APHID (Aphis medicaginis Koch)

Arizona. C. D. Lebert (April F): The bur clover or cowrea athid '7as observed
on th: ti-os of citrus trees in the north Phoenix citrus area. 17' serious
injury noticeable.

WHIT ELIES (Dialeurodes sin.)

Florida. J. R. Watson (April 21): In most sections of the Citrus Belt thr
seems to be an unusually heavy flight of whiteflies this year. D. ciri
Ashm. has largely em 'rged in the o'uthern cart of the Citris t, v2;
is just beginning to appear in the northern rart around Monticl c-
cording to S. 0. Hill. The cloudy-uin -d snccieC.s(]. citrifoli] Mor.)is
beginning to appear in the main part of the Citrus Bolt.

Mississippi. C. Lyle (April 21'): Infestations of 'hitefly on citrus have
been observed in HIrrison County and on cape jasmine in L?.uderdale County.

COTTOIY-CUSHION SCALE (Icerya. Pr-hvci Mask.)

Georgia. T. L. Bissell (Aoril 5): More than usually prevalent in southern
Georgia counties during the winter and sprinF. I have reoorts from
Claxton, Evans County, and Reidsville, Tattnall County, both in south-
eastern Georgia. The first was in satsuma orange, the second not
specified.

Alab-ima. J. 21. Robinson (April 22): Active on shrubbery at Geneva the first

Arizona. C. D. Lebert (Aoril 20): California red scale a' n-rently absent
this spring in the Phoenix area. Unable to find a single live sc-ale.
We hope the pest has j .'. eradicated.

CITRUS THRIPS (Scirtothrips citri Moult.)

California. R. S. Woglum (Anril): Citrus thrips have been hntc1in,- for 2 or
3 weeks in central California and in some places are now fairly abunant
in ipite of the cool and rainy weather. OC,.,ing to the deiayerd and pro-
longcd hatch the thrins will not aptrear to be as abundant as they some-
times are at this time of yea.r. Thrips have been hatchin more or less
FpTj)radicaI'.l since the mC. 2 1e of March, but in the past few days have
become numerous in some orange orchards in eastern San Bernardino Cbunty.
Theyr are also ape-rinp fre-:ly in occasional lemon orchards, esoeci-illy
in San Bernardino County in orchards that suffred cons i der,.b'le thrips
damage last year.

C. S. Morley (Anril 2): The first citrus thrins were found in
the Edison district, Kern County, on i&rch 12.

TOMATO PINWORM (Gnorimoschema lycopersicella Busck)

Florida. E. W. Berger and G. B. Merrill (April 20): Tomato pinworm infesta-
tion in the southern half of the State:., peninsular section, is light and
has occasioned little if any loss; apparently of long standing but never
sufficiently severe to attract attention, of growers. First reported in
Florida from Bradenton, 40 to 60 miles south of St. Petersburg and Tampa,
respectively, in Manatee County, in 1932.

California. J. C. Elmore (April 20): Moths observed flying from tomato
plant pile in Orange County. A potato field nearby is lightly infested.
Moth emergence from under dead tomato vines was common in March, five

out, beginning February 1. The cold weather in January killed all tomato
vines on which the pinworm often continues development throughout the
winter, Survival in the pupal stn'ge, however, has been greater than was
expected. (April 21): In an early tomato field near San Pedro, Los
Angeles County, 10 plants out of 30 examined were infested. Twenty leaf
folds were found. Volunteer tomato plants occurring by the thousands in
abandoned fields from last year at Long Beach, Los Angeles County, are
heavily infested. (April 22): An early tomato field in the upland area
east of Santa Ana, Orange County, is infested. Fourteen, pi~nworms were
found on the leaves of 5 out of 10 plants examined.

Florence County, consisting of 9-1 acres of tobacco that had been trans-
planted on April 6 to 8, were found to be severely injured by this pest.
Examination showed that owing to cool weather the plants had not made any
appreciable growth; consequently the flea beetles had severely injured
the young plants after setting in the field. Blue mold was also a con-
tributing factor in the death of many of the plants examined. Although
only a small area of th 9- acres was exriin'd, the grower was of the
opinion that at least 85 percent of his plants would have to be replanted.

Florida. F. S. Chamberlin (March 22): The few flea beetles present in the

COTTON I INSECTS


... "BOLL TEEVIL (Anthonomus grandis 3oh..)

Georgia. P. M. Gilmer (April 17): Indications are that the survival of
hibernating weevils will be greater than usual, but 'because of the.
light population that went into hibernation, .the.initial infestation
will be rather li ht. In the hibernating cages the weevils are moving
6ut in numbers that'wouild also indicate a survival above normal,' at
Tifton, in southern Georgia.

S0. I. Snapp (April 26):, The first adultof the season was observed
today at Fort Valley. *It was jarred from, a peach tree, which was un-
usual, as the boll weevil is seldom taken on peach.

Louisiana. R. C. Gaines (April 27): Three :boll"weevils were taken on"scireen
traps at ITallulah (Madison Parish) on April 17. The record of boll
weevils taken on nine flight screen during the past month, as compared
with the same periods in 1935 and 1936, is as follows:

Date : 1937" ` 1936 : 1935

April 3 -------- : 0 .1 :
April 10----------- : 0 0 : 6
April 17 ------ -. : 0 .3
April ---------: 2 : 0 : 0


Texas. R. W. Morelhnd (Aoril 27): At College Station, in south-central
Texas, the number of weevils found but of hibernation in the cages
increased from a tot.1a of 146 during the week ending April 10 to 703
during the week ending April 24.

F. L. Thomas (April 17): It is believed thrat boll weevils will be
more sbr'Thnt in southern Tex.s than usual, especially on young cotton.
Last year's cotton wp.s not killed and the weevils have been active and
breeding throughout the winter. In portions of central Texas the early
infestation is not expected to be as heavy as last year. The large
-.mount of poisoning last fall end the destruction of unpoisoned foliage
by leaf worms (Alabrrma argillacea Hbn.) contributed to a reduction in
the number of weevils to enter hibernation. The survival of those that
did go into winter quarters appears fairly high at this time. (April 24);
Boll weevilsao,ve been flying f .,nd are seeking cotton. They already have
been taken on screen tr]ps in weeds and in cotton fields at a consider-
able distance from winter shelter.

PINK ?OLL70RM (Pectinophora jossypiella Saund.)

Tex-is. A. J. Cha l:r. (April 24): There was a heavy emergence of moths from
the hibernation cages during the week at Presidio, in the Big B, nd of
Texas. The emergence thus far indicates that there will be a heavier
carry-over thin year thr,n last.

SALT-lkYRS:T CATERPILLAR (Estigmene acraea Drury)

Texas. F. L. Ti-,...s: Adults and eggs are rather comr.mon in the coast
counties north of Corpus Christi, where there is likely t-o be more
trouble than usual.

Cr'ITr': FLEA HOPER (Psallus seriatus Reut.)

Tex-s. F. L. Thomas (April 17): The insects began hatching from over-
wintered eggs in the croton weeds as early as February 18 at College
Station and, with the e-ception of 9 days when it w:as too cold, have
been hatching every day since. Although niny of the early hatched
insects were killed as a result of a few hard rains on cold days,
recent observations indicate that there are large numbers of eggs that
have not hatched. (April 24): If weather conditions are such ao to
promote the growth of cotton during the remainder of the- sring, severe
flea hopper injury may be expected. The hatch from overwintered eggs
during the period Aoril 1-15, inclusive, exceeds all records. The
average hetch for that period this ynar was 5,623 insects -oer 100
croton reeds collected from 8 counties in .outh-central Texas. The
next highest emor-. ncc was in 192o, a flea-ho er vear, when n4,'M
insects hatched from 100 weeds. In 1935 oand 1930 the hr'tch during the
same period amounted to 1,000 and 1,106 flea hoprers, respectively.
In thr- loweer Rio Gr?.nde Valley north of Woslaco no flea horoers have
been seen and no d-n-sc' has been found on cotton that is from 6 to
8 inches tall and is squaring. They have been reported on cotton in
Bexar County.
