Reports from Missouri, Okl-homa, and Colorado indic to that rrass-
hoppers rcassd 0che -~inter with very little mcrta ity. 's ar rc' nt in
large numbers in pr,,ctic'lly every county in Missouri. In the Inperial
Valley of COlifornia Melinoplus mexic'-nus S.uss. began hatching the third
week of March.

Mormon crickets began hatchin'. during the month in Montan-,, Colorado,
and Utah.

A heavy northern flight of the Monarch butterfly was obcserved in
Ventura oumf-", Calif.

Wire'.7orns ere reported in destructive numbers in sports of Louisia.na.,
Colorado, and California.

Winter mort"lit-y of chinch b'. in Issour is report, 5 as very lo-;.

The outbreak' of the greon buT in parts of the Southe- st is rapidly
torminati:.:. Similar conditions a.re reprrted of an outbreak in north-
central Oklahoma.

The codling moth is reported as having r7",,!sei the ",irtor with but
little mort-lity in Gcorria -nJ Mi-souri, 'jhCre s in Ilaho cnly 0 P .rccnt
of the larvae survived- tie winter in thI,: south. .-tern t 'art of thc- State,
where temperatures rea.ched 28 below zero, lte in January.

Winter mort-ality of the Saxn Jose scale ,:ar reported ,s below normal in
Virginia and Georgia. In the .Mid-rest andi Pa.cific Yorthw:est the car .--over
was comparatively light.

Althou"h, the plum curculio b!. -' n t, emerge earlier than ufu-.l in Oairts
of Georgia, the main emer :-. r.ce from hibermnation i. decidedly behind th- bloom-
ing of poach trees in that section.

I NSECT











The green citrus !-phid is extremely abundant in the main Citrus Belt
of southern and central Florida.

The tomato pinworm is reported oas having successfully passed the
-inter out of doors in the vicinity f Kennett Square, Pa. This insect
appDarnud much earlier than usual in Manatee County, Fla. It has also been
reported from Dade County, Fla.

Several ne7 infestations of the sw.eetpotn.t weevil have been found in
Mississi-D-i. It ha),s been possible to trace many of these infestations to the
movement of swe.otpotma-o plants.

Reoorts from thie Big Bend of Tex!s indicate that the pink bollworm
p!% ssed the winter pith very little mortality.

Activity of screwvorms is confined principm.lly to the overwintering
areas of Florid:, and southern Georgia and the extreme southern part of
Texas.

GEi:ERAL FS3DSRS


G.ASSHOFPBS (Acrididae)

Missouri. L. Haseman (March 214): Recent limited observations indicate that
grasshopper eggs have survived the w,,inter very ell and, ith 100 of
ll4 counties carrying rather heavy supplies of engs, we are e:v.-- :ting
much trouble this summer, particularly if it should be dry.

Oklahoma. F. A. Fenton (March 20): Examination wa.. made on March 18 to
determine the condition of eg;s in an e<.; bed of 1Melanopmlus differ-
entialis Thos. In the more sunny -o)',rt of the bed the embryos hove
developed to the r'oint where the eyes are visible throu h the shell.
Most egs.o, however, have not developed this fr. All pods e.:amined
were in ;ood condition, but there is evidence of considerable destruc-
tion of pods by ground-beetle larvae.

Montana. H. B. Mills (mrch 25): NKa.ieros reports of over.irintering grass-
hoppers, largel'- Ciorto-ophaga virieifasci-ta Dec., becor.ming active.

Coloraoo. S. C. McCamrbell (Mrch 8): CG-rasshopper eg3s crme through the
winter in good condition throughout northeastern Colorao0o.

California. S. Lockwood (March 27): Grasshoppers are now hatching in con-
siderable numbers in alfalfa fields at Wetmoreland, Im-perial County.
Most of the nymphs of ,. 1:exicanus Stuss. examined \7ere in the first
instar, but a fe,. seconc-instar nymphs :?ere observ; d. Four or five
grasshopper? were- collected at etch sweer of a standard insect ne;.
This is probably less th'n half of the ho-o)ers pre:tnt, as i-any of them
wE re entan!ld in the high alf-alfa an did not f11 into the n t.

I....:. CRICKET (An.brrs simplex Hald.)

Montana. H. B. Mills (Mrrch 25): Mormon crickets are just berinninF; to
hatch in southern iMontana, in Big Horn r.nd C-'rbon Counties.

Colorado. C. R. Jones (March 26): -,rmi-on crickets are hitchin,- in .offat
County, in northwestern Color.do. iost of this infesto'tion, hove:ver, is
still under 2 feet of sno-v.

Utah. C. J. Sorrnson (::-.rch 2?): Mormon crickets b z-.n h.,tching on March 6
in several loc.litics in Millard County, central UtAh.



Missouri. L. Haseman (March 24): Strnwber-. .' {ro'r in southwestern Missouri
report wh'st seems "o be early work of cut' orm!s in vtru.7bh.rry field .










ARMY CUTWORM (Chorizagrotis auxiliaris Grote)

Colorado. S. C. Mc-Campbell (March 8): So far reports of the army cutworm
from Arapahoe County, near Denver, are not as general as last year, but
it is a little early and a large territory has not yet been surveyed.

SOUT=3RIT ARIOf O1. (Prodenia eridania Cram.)

Florida. J. R. Watson (March 22): The semitropical armyworm has been
abundant throughout the southern third of the State.

WHITE-LINED SPHINX (Sphinx lineata F.)

California. R. E. Campbell (March i4): An adult of the striped sphinx was
seen hovering over narcissus blossoms at Alhambra this evening.

MONARCH BUTITE.RFLY (Danaus menippe Hbn.)

California. F. H. Wymore (March 20): Thousands of butterflies were observed
at the eastern edge of Venbura City, flying north toward the mountains.
I had never before seen such large numbers of this species.

TIRET.M)S (Elateridae)

Louisiana. C. 0. Eddy (March 24): Wireworms are damaging the eyes of seed
sugarcane in several 10- or 12-acre tracts in southern Louisiana.

Colorado. C. R. Jones (March 26): Wireworms are reported from Adams County,
northeast of the central part, as damaging wheat and also from Montrose
County, on the western border. I do not know whether these are the
true or false wireworms, as no specimens were submitted.

California. M. W. Stone (March 3): Male adults of Lirmonius californicus
.-r.n. were collected on alfilfa near Artesia, Los Angeles County, on
February g, and at Smelzer, Orange County, on February 17. Males began
to emerge from laboratory cages on February 'l6 and females on February
19. Larvae ,ere recovered in large numbers in Orange County on wild
barley and malva in bean fields on February 24.

WHITE GRUBS (Phyllophaga spx. )

M- r 'land. E. 1%. Cory (March I1): Grubs w,,ere observed at Hagerstown, in
western Marylind.

Texas. F. L. Thomas (March 9): On March 9, a female P. calceata Lec. was
taken at olce.; Station, On March 24, a female P. hirtiventris Horn
was tain at a light at College Station. These are the first records
for the- scon,







C0M;rOIT REF SFIE:. (Tetranychus telarius L.)

Virginia. H. G. TWlker (March 24): Red spiders are rather scarce in most of
the str'w7b.'rry fields examined in southeastern Virginia.

Missouri. L. Haseman (March 24): In northwestern Missouri, where for the
last 3 years the red spider has been a serious problem, particularly on
raspberry, blackberry, and apple trees, our field man, Lee Jenkins,
reports that thley have passed the winter in much smaller numbers.

Arizona.. C. D. Lebert (March 15): Rather severe webbing of T. telarius on
many of the Italian cypress and some of the arborvitae in the Phoenix
district. Some of the trees were brown and severely webbed.


CEREAL A 7D F ORAGE-CROP I TSECTS

Ti-EAT

::SSIAN FLY (Phytophaga destructor S1.y)

Missouri. L. Haseman (March 24): With the severe set-back which the wet
spring of 1935 gve to the hessian fly in :.issonri, th. pcst did not
rebuild its populations seriously during the summer r n8 fall of 1936;
however, in northeastern Missouri f.nd in sc'.ttcred are'2s throughout
the rest of the State some early seeded fields are showinr. rather seri-
ous winter carry-over. The winter mortality seems to have been very
light.
C:-:1u1H BUG (Blissus leucorpterus Say)

Missouri. L. Hasernan (March 24): W7inter surveys indicate that '.. chinch
bug infestations in Missouri are spotted, with occasionally abundant
carry-over on individual f.rms. The winter mortality seems to have
been low, and the two gnnorWl arers where hibcrnating `u.-s are most
abundnt are the northwestern and the west-centr.l counties, with a
general sprinkling throughout most of the area north of a line from
the southwestern corner of the State across to St. Louis.

"rEE' BUG (Toxoptera grTaminum Rone.)

South Carolina. F. Sherman (March 29): Complaints; of aphids on small grains
have come frr-m 11i parts of the Statr. T. gr- -ixr.m and o'her .-r'-in
aphids perhaps have been involved. P-rr.sites rnd predators have helped
to check the aphids.

Georgiar. T. L. Bissoll (Ma1rch 25): At E-'r.rirnent (central Georgia) small
numbers of a-ohids are working, but the oats seems to be t,.yond further
injury. Bare patches of dead oats are evident in fields. Since the
report a month ago I have heard of injury in T Ibot, Jasper, and
Fr:-.',nkin Counties.


-)7-









Oklahoma. F. A. Fenton (March 20): On March 11 a trip was made to the wheat
sections of north-central Oklahoma, in Garfield and Kingfisher Counties,
and on March 1i to sections of Noble and Payne Counties. The green bug
is present in only a few fields and is apparently in about the same
condition as it was last January. No further killing of plants has been
noticed and the infestation is very spotted. Parasites are also present
in a few places. We do not anticipate serious trouble from this pest
this year.

ALFALFA

ALFALFA 7REVIL (Hypera postica Gyll.)

California. A. E. Michelbacher (March 22): On March 15 the weevil was
abundant in a single field in the San Joaquin Valley near Patterson,
where an average of 197 larvae and 35 adults were collected in 100
sweeps of an insect net. In other fields examined the larval count was
generally less than 30 per 100 sweeps. In the San Francisco Bay dis-
trict on March 18 the highest average larval count per 100 sweeps was
158. In other fields examined it was below 25. At Pleasanton on
March 18 only 3 larvae and 1 adult were collected in 600 sweeps. Adults
of Bathyplectes curculionis Thoms. were found throughout the infested
region. In the San Francisco Bay district a high percentage of the
alfalfa weevil larvae were parasitized, while in the most heavily in-
fested field in the San Joaquin Valley a smaller percentage appeared to
be parasitized. The weevil population is much lower than a year ago,
when counts of 1,000 or more were not uncommon; however, the alfalfa was
more advanced than it is this year.

LEAF EETLES (Diabrotica spp.)

Oregon. B. G. Thompson (March 3): D. soror Lec. is numerous and damaging
young clover in the Willamette Valley.

California. J. Wilcox and M. W. Stone (February 3): The following chrysome-
lid beetles were taken on alfalfa near Alhambra, Los Angeles County, in
their order of importance: D. soror, L. balteata Lec. Gastroides
cyanea Melsh. and D. trivittata M.rnn.

S. Lockwood (March 27): The 12-spotted cucumber beetle (D. duo-
decimpunctata F.)is numerous in alfalfa fields in Imperial County, in
the southern part of ;he( State.

PEA APHID (Illinoia pisi Kalt.)

California, S. Lockwood (March 27): The pea aphid is more than ordinarily
rilirrirous in alfalfa at Bard, Imperial County, in the extreme south-
eastern corner of the Stat .








Orerc-. K. Y. Gray and T7. D. Edwrds (March 3): Egs )re hatching near
Astoria, Clat)oon County, in northwestern Oregon.

California. J. Wilcox and M. W7. Stone (March 18): Pea aphids .7ere much
more abundant on alfalfa, at Downey, Los Angeles County, than last
month. Syrrhid larvae were common.

TKE-CC?.?-. D ALFALFA HOPPER (Stictocephala festina Say)

Louisiana. E. 0. Ellisor (:.!.rch 24): The alfalfa -irdler (S. festina) has
been active and oviposition has continued in southern Louisi during
warm periods throughout the winter. A small percentage- of these e-gs
hatched during warm periods in F',-bruin-rU and the early part of .'ch;
however, the nym-ohs were killed by cold weather. Large numbers of
nymphs hatched from March 17 to 24. A microscopic examination of about
50 alfalfa plants showed that most of the eggs were deposited at least
2 inches above the surface of the soil.

California. S. Lockwood (March 27): The treehopyer (S. festina) is common
in alfalfa throughout the Imperial Valley but d'amae is not apparent.

ALFALFA CATEFPILLAR (Euryrus eurytheme. 3dv.)

Idaho. R. W. Haegele (March 19): A heavy infestation of the alfalfa c-ter-
pillar was found in a 1936 seeding of .lfalfa in southwestern Idaho.
The larvae avera-ed 1/2 inch long and have been feeding since early in
March on the green growth that had come through the winter. From e-.rly
in January until March 1 the field was covered with 6 to 10 inches of
snow and the minimum temperature during January wrs -27o F. at Weie-r.
The larvae became active as soon as the snow melted enrly in March.
This insect is recorded as spendinF the winter in the Northern States
in the pupal stage and as larvae in the warmer States. The larvae in
this instance have lived through the winter.

COT7FEAS

CC'T-EA CUijRCULIO (Chalcr^dermus aeneus -oh.)

North Carolina. Z. P. Metcalf (March): Co'woea weevils are ->nerally more
akunrdant on coxpeas than usual.

SUGARCAE

SUGARCA-E BORER (Diatraea sacchar-alis F.)

Louisiana. C. 0. Eddy (March 21): Larvae of the sug.-rcane borer are
transforming to pupae rapidly in southern Louisian A few moths have
emerged. Most larvae and pupae are being found in the tops and in
trash; very feu in stubble.

FRU I T I N SECTS

APPLE

APPLE APHIDS (Aphiidae)

Virginia. W. S. Hough (March 1ig): Aphid eggs are not plentiful in apple
orchards at Winchester, northern Virginia. FRll migration to the apple
trees was greatly reduced last October and November, and about 10 per-
cent of the winged forms at that time were rosy aphids (Anuraphis roseus
Baker).

Missouri. L. Haseman (March 24): There seems to be a scarcity of aphid eggs
on fruit trees throughout central Missouri.

Idaho. R. W. Haegele (March 19); Eggs of the rosy apple aphid (A. roseus)
are moderately abundant ond starting to hatch in southwestern Idaho.
Practically all the eggs seem to have survived the winter in south-
western Idaho, where minimum temperatures in January ranged down to
-2S F.

LEAFHOPPERS (Cicadellidae)

Missouri. L. Haseman (March 24): Winter mortality of leafhoppers at Columbia
has been rather low, on the average not more than 10 to 20 percent. In
northwestern Missouri they show 25 pErccnt mortality in leaves and from
50 to 100 percent mortality in bluegrass.

CODLING MOTH (Carpocapsa pomonella L.)

Georgia. C. H. Alden (March 24): Larvae still in hibernating cocoons at
Cornelia, in northeastern Georgia, but there has been no pupation to
date.

Missouri. L. Haseman (March 24): Lee Jenkins reports that in northwestern
Missouri practically 100 percent of the overwintering worms are alive.
In our breeding material at Columbia the winter mortality is very low.
In southwestern Missouri the carry-over of worms is heavier than at any
other place in the State. Generally overwintering worms are less numer-
ous thpn they have been any year since the late 1920's; but, with con-
ditions now favoring a fair-to-heavy set of fruit, our growers will be
obliged to spray thoroughly to prevent the insect from increasing in
numbers in 1937.

Idaho. R. W. Haegele (:>.'ch 19): Only 10 percent of the larvae survived the
winter in untreated corrugated paper bands on tree trunks in the south-
western port of the State. T7hore the bands were covered with burlap
sacks, 85 percent of the larvae were alive. The lowest temperature
reading for the winter was -28 F. on January 21, at Parma, in the
southwestern part of the State.

EAS:7"?:. T-"T CATERPILLAR (Ma]acnsoma -.mericlana 7.)

North Carolina. 17. A. Thomas (March 9): This insect was observed at Chad-
bourn, where it was just beginning to web in wild cherry leaves just
coming out.

Kentucky. 7. A. Price (March 26): Several egg masses of the a-prle tree tent
caterpillar have P:en received from Hodgenville and vicinity. :.-se
received today were hatching.

Ark-,ncsi. 77. J. Baerg (March 20): Hatching of eggs in northwestern Arkansas
was well under way on March ig and probably began on .'-rch 17, or earlier.

Tex-.s. R. K. Fletcher (March 17): T-rms nearly ;-r:1 on plum trsrep in eas-t-
central Texas.

FLAT.TM'rED APPLE TREE :?. (Chryzobothria fenorat. Cliv.)

Missouri. L. Haseman(Ma1rch 24): This rest was again very abundant last v.,:ar
and recent observations indicate thft it is surviving the winter in large
numbers and in healthy condition. On exposed limbs and tree trunks, how-
ever, hairy and downy woodpeckers have been very active in feeding on
the borers.
OU:Tc1H.A_ r_ APPLE 7-7J _-:O ER (Saperda candida F.)

lMissouri. L. Haseman (March 24): Over the State generslly the carry-over of
this borer has been less heavy than for the two or three rer-. 1i-"
seasons, but some orchard men report rather alarming infestations.

SAY JOSS SCALE (Aspiiotus pernicious Comst.)

Virg-ir.i-. 77. S. Hough (March 1iS): -:':ination of scales in one orchard in
northern Virg inia, where the infestation is moderctzly severe, showed
that about 60 -percent of the individuals were alive, which is somewhat
in excess of the usual -ro rrtion cf live individuals (::oected at this
time of the year. This insect, although pres; nt in orchards, is
not as abundant as it was a fe-: years ago, and careful se.r.rhi-..: is
r,.quired to locate sufficient numbers to make a count in neglected
orchards.

ri ryland. E. II. Co:-,' (March 11): San Jose sc.le obs:-rvwd at Y..)yal Oak.

Georgia. 0. I. Sna-pp (March 22): A-i re has be;n no morta-lity of the Se-n
Jose sc'.le at F-ort Valley from lov- temn craiures durir-n the winter, and
the unusua-lly mild winter permnitttd uninterrupted rerroauction, esp ci-
ally in rnspr'-yed orch,.rds. The inf. station is n-ow re ter tr:.n that
of an avura-, year, as the perccntg- of live stcle w,'as unusually high
at the pgir.r.:.- of the winter. Of 13, sc-o'l-s county d unAr a i-
nocular microscope in November, 95.5 .rccnt cru alivw. orcnt-
agc of live scale in the same orchard in January war- 9. 9 perc-ent.






-52-


Georgia. C. H. Alden (March 24): San Jose scale continues to be abundant on
peach and apple trees at Cornelia, in northeastern Georgia, especially
in unsprayed or poorly sprayed orchards.

Illinois. W. P. Flint (March 23): There has apparently been no increase in
San Jose scale mortality during the past month.

Missouri. L. Hrseman (March 24): Observations of San Jose scale in central
and northeastern Missouri indicate a rather light carry-over of live
scale. In southwestern Missouri there is an increased demand for dor-
mant-spray materials, indicating that considerable spraying will be done
before buds open.

Idaho. R. W. Hc.egele (March 19): Scale counts from several districts in
southwestern Idaho showed from 70 to 85 percent winter mortality. Low
temperatures in January ranged from -20 to -28 F., for a few hours'dur-
ation on only 1 day, which probably accounts for the relatively high
survival.
SCURFY SCALE (Chionaspis furfura Fitch)

Virginia. W. S. Hough (March 18): Scurfy scale very abundant in many apple
orchards throughout northern Virginia.

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

Vermont. H. L. Bailey (March 26): Eggs reported moderately abundant in
southern Vermont, with considerable percentage of them dead or para-
sitized.

Massachusetts. A. I. Bourne (March 12): The red mite was unusually abundant
in all orchard sections late in the summer of 1936. Growers find that
although there was an unusually heavy deposit of eggs last fall, in many
instances many of them have been killed, Apple twigs containing the over-
wintering cocoons of a small neuropteron, Conwentzia hageni Banks, are much
more numerous than for many years., and are especially abundant in the
orchards where the red mite was very numerous last fall. I do not know
whether there is any association between the neuropteron and the red mite.

PEACH

FLUI! CURCULIO (Conotrachelus nenuphar Hbst.)

,eorgia. 0. I. Snapp (March 19): Plum curculios have not yet appeared in
numbers from hibernation at Fort Valley, although full bloom of peach
trees is past. They are usually disseminated throughout the orchards
by full bloom. Peach trees began to bloom unusually early this year,
and with the curculio being held in hibernation later than usual, as
compared with the development of the fruit, Georgia peaches may escape
an attack by the second brood.

C. H. Ald n (March 24): Jarred 20 trees in Elberta peach orchards
in northeastern Georgia on March 23 but caught no curculios. Orchard
in full bloom.







T. L. Bissell (March 25): We have jarred peach trees and wild r.lum
trees three times a week at Experimewnt, central Georgia, since lirch 3,
but so far have not taken any curculios.

CUCUM:-ER BEETLES (Diabrotica spp.)

Georgia. T. L. Bissell (March 25): Beetles, D. duodecimpunctata F. have
been common on peach and wild-plum blossoms at E:.Xperiment since March 5.

California. S. Lockwood (March 6): Tihe cucumber beetle D. soror Lec. appar-
ently has wintered over in more than normal numbers. They are now easily
found in a number of wild plants, particularly in miner's lettuce k(Montia
perfoliata?). Considerable alarm h..s been expressed by growers of apri-
cots and early peaches as this beetle was responsible for a considerable
loss of tonnajge of early peaches and apricots in the Sacramento Valley.

FEACH 2C'RER (Conopia exitiosa Say)

North Carolina. Z. P. Metcalf (March): The peach tree borer has been general
throughout North Carolina.
ORIEUTAL FRUIT MOTH (Grarholitha molest Busck)

South Carolina. F. Sherman *(March 29): Adults are being caught in traps at
Clemson, in the western part of the State.

BLACK PEACH APHID (Anuraphis persicae-ni-er Smith)

South Carolina. F. Sherman (March 29): A considerable number of complaints
of the black peach aphid have been received. The forms above the
ground, as well as those below the surface, were reported.

PEAR

PEAR TBIPS (Taeniothrins inconsequens Uzel)

Oregon. S. C. Jones ('.I- r'ch 3-10): Pear thrips were emerinp on 2,!arch 2 in
the Umpqua Valley, in southwestern Oreg'on, and on March 10 in the 7illa-
mette Valley.
C "7r.?.Y

CH.' Y SCAL: (As-oidiotus forbesi Johns. )
Virgini-:. W. S. Ho'i.-hL (March 18): Cherry scale -.as very abundant in a large
sour-cherry orchard near Winchester. This orchard has never been sprayed
for scale, although the trees have been bearin: fruit for a number of years.

RASPI- -WTy

RED-:ECFED CA:- BOPEC (A-rilus ruficollis F.)

Oklahoma. F. A. Fenton (March _0): Reports have been received of severe
dar-i.--.* by the red-necked raspberry cane borer to blackberrieo, de(`berries,
and youngberries, all important crops in Oklahoma.

GRAPE

GRAPE LEAFHOPPER (Erythroneura comes Say)

California. C. S. Morley (March 8): Grape leafhoppers are very abundant in
Kern County. Vineyards are being plowed and trap crops left for the
leafhoppers to hibernate in for the remaining few days of hibernation.
The hoppers are very active during the present warm weather.

PECAN

OBSCURE SCALE (Chrysomphalus obscurus Comst.)

Louisiana, C. 0. Eddy (March 24): Obscure scale is reported very numerous in
northeastern Louisiana.

CITRUS

A LONG-HOR=ID BORER (Prionus sp.)

Arizona. C. D. Lebert (March 1): The large larvae of P. californicus Mots.
or P. heroicus Semen., or both, have been found in several citrus groves
northeast of Phoenix. Severe tunneling and, in some cases, complete
girdling of the trunks from 3 to 6 inches below the soil level have been
observed. There are from one to six larvae per tree.

GREEN CITRUS APHID (Aphis spiraecola Patch)

Florida. J. R. Watson (March 22): The green citrus aphid has been extremely
abundant during the last month. The spring flush of growth has been pro-
longed over an unusually long period this year, affording the citrus
aphid a continuous food supply. It is extremely abundant in the main
Citrus Belt of central and southern Florida. The Chinese -ladybeetle,
Leis dimitata quinQuedecimspilota Hope, has continued to spread and has
now reached Seminole County, in central Florida, and is in Broward
County, in the southeastern part of the State.

COTTON APHID (Aphis gossypii Glov.)

Texas. S. W. Clark (March 19): Abundant on limes and certain species of
oranges at Weslaco.

PURPLE SCALE (Lepidosaphes beckii Newm.)

Louisiana. C. 0. Eddy (March 24): Purple scale is common on citrus in
southern Louisiana.
CITRUS RUST MITE (Phyllocoptes oleivorus Ashm.)

Louisiana. C. 0. Eddy (March 24): It is re-orted that the citrus mite is
unusually numerous because of the mild winter.

?'TAI-ELS WEEVIL (Li-troderes obliquus Klug)

Florida. J. R. Ttcon (March 22): Many complaints of the denoredations of
the v-- etable weevil, especially on carrots and beets, have been re-
ceived from the northern part of the State.

Louisiana. P. K. Harrison (March 24): Th-.- vegetable weevil is still gener-
ally abundant, injuring turnip, mustard, cabbage, and other plants, in
southern Louisiana.

S. S. Sharp (March 24): Vegetable weevil larvae were found feed-
ing on strawberry fruit at Independence, in eastern Louisiana.

SPOTTED CUCUPER -ZTLE (Piabrotica duodecim)unctata F.)

been active on warm days throu-hout the winter in kale, collard, spinach,
rye, and other fields at Norfolk.

SEED CCUI: MAGGOT (Hylemyia cilicrura Roni.)

Virginia. H. G. T, lk -r (March 24): Adults of the seed corn :v-,ot are
rather abundant at Norfolk.

G?.:: PEACH APHID (1Myzus persicae Sulz.

Norfolk.

Utah. G. F. Knowlton (March 1): Aphids, M. rersicae, were seriously abun-
dant on sugar beets in an experimental greenhouse at Logan.

TOMATO

TOMATO PI':7:: (Gnorimoschema lycorersicella 3usck)

Pennsylvania. C. A. Thomas (March 22): The tomato pinworm is now restricted
in Chester County, southeastern Pennsylvania, to four greenhouse estab-
lishments in the vicinity of Kennett Square; however, studies indicate
that it survived the mild winter out of doors, hence it may spread .Lp-
idly this spring. There was no evidence last spri-.-- that it had suc-
cessfully hibernated out of doors through the severe winter in this
vicinity, and all individuals found, here last spring undoubt:ily came
from nearby greenhouses, where thy had passed the winter on the -row-
ing tomato plants.

Florida. M. D. Leonard (March 17): A letter just-received from the County
Atnt of Manatee County states th t the tomato pinworm has ar. red nmch
earlier than usual at Bradenton on their big tomato crop. The insct has
been found in Dade County from Miami to Homestead.

A CHIRONOMID (Camptocladius sp.)

Pennsylvania. C. A. Thomas (March 22): An unusual injury to recently potted
tomato seedlings was found in a greenhouse at Kennett Square, south-
eastern Pennsylvania, in February. The seedlings fell over on the soil
as if"daroped off." Examination revealed that each plant had been bored
into just below the surface of the soil and then hollowed out by these
tiny larvae. The larvae had probably come from the barnyard manure with
which the potting soil had been mixed, and after the manure became dry
they attacked the tomato plants.

BEANS

POTATO LEAFHOPPER (Empoasca fabae Harr.)

Florida. M. D. Leonard (March 17): During January and February there has
been one of the worst infestations of the potato leafhopper on string
and lima beans that has occurred in several years in the lower east
coast of Florida and along the eastern shore of Lake Okeechobee.

CABBAGE

IMPORTED CABBAGE WORM (Ascia rapae L.)

Virginia. H. G. Walker (March 24): Nearly full-grown imported cabbage worms
were observed feeding on collards the middle of January at Norfolk. A
few imported cabbage worm butterflies have been observed flying over
kale, collard, and cabbage fields during the past week.

North Carolina. W. A. Thomas and F. A. Wright (March 8): Adults.of the com-
mon cabbage butterfly have been intermittently active in the vicinity of
Chadbourn most of the winter, no doubt due to the abnormally high winter
temperature.

South Carolina. F. Sherman (March 29): The white cabbage butterfly was in
flight as early as February at Clemson, but we have no complaint of damage.

Louisiana. C. E, Smith and R. W. Brubaker (March 24): Adults have been ac-
tive and ovipositing for 2 weeks, and a considerable sprinkling of larvae,
mostly of the first instar, are present on cabbage at this time, at Baton
Rouge.

Virginia. H. G. Walker (March 2.L): The larvae of the diamondback moth con-
tinued to be auite destructive to kale and collards until about the
middle of January at Norfolk; howc.ver, all stages of this insect are
rather scarce, while its hymenopterous parasite, Angitia hellulae Vier.,
is rather abundant.
Louisiana. C. E. Smith and R. W77. Brubaker (March 24): The larva of the
diamondback moth is relatively scarce on the experimental cabbage plant-

ber of the Pest Survey Bulletin, is represented in A. L. Melander's priv-
ate collection by two specimens one taken on May 26, 1908, at Nooksack,
a few miles from the Canadian border in Whatcom County; the other on
May 17, 1910, at Olga, on one of the islands of Puget Sound.

TUTVTIP

TUinTIP APHID (PRhopalosiphum pseudobrassicae Davis)

Louisiana. P. K. Harrison (March 24): The population of the turnip aphid is
increasing on turnip and rmistard in the vicinity of Baton 'Rouge. Para-
sites of this insect are also becoming more numerous.

LETTUCE

POTATO APHID (lllinoia solanifolii Ashm.)

Georgia. T. L. Bissell (March 19): Aphids abundant on lettuce on one garden,
at Griffin, in central Georgia.

STRAT7BERRY

STRAW7BERRY 7WEEVIL (Anthonomus signatus Say)

North Carolina. W. A. Thomas and F. A. Wright (February 9): Owing to the
unseasonably warm weather of January which caused huckleberries to bloom
heavily early in February at Chadbourn, some weevils emerged from hiber-
nation at that time. The cold weather in February caused the weevils to
cease emerging and up to March 12 no further emergence had been observed.

STRAWBERRY ROOT APHID (Aphis forbesi Weed)

Virginia. H. G. ,Talker (March 24): Strawberry root louse eggs were hatching
at Norfolk on January 22, about 2 months earlier than eggs hatched last
year. The eggs and young aphids were very scarce in every field examined
and very little injury is expected.

SWEETPOTATO

S-EETFOTATO WEEVIL (Cylas formicarius F.)

Mississippi. C. Lyle (March 24): During the past few weeks several new in-
festations of the ,weetpotato w7eevil have been found in southern Miss-
issippi. A considerable number of infested properties have been found
in Pike and Jefferson Davis Counties with smaller infestations in Amite,
Lawrence, and Jones Counties. The ne- areas are being placed under
quarantine.

FEPFER

PEPPER 7EEVIL (Anthonomus 7-. 11- 1 C'n)

Florida. J. R. -.tson (March 22): In two or three infestations in M1:natee
County the pepper weevil has become so v'.i:,nt as to destroy all rceppers
and most of the bloom.
SUalR :,--

7-.T LEAFHOPPER (Eutettix tenellus F r)

Utah. G. F. Knovlton (March 10): Beet leafhoer-ers a r r- ther abundant on mus-
tanrd hosts at Genola and moderately abundant near Lamro, in northern Utah.



T'BACCO LEA BEETL (-irix rvI-, 1la 1)

North Carolina. Z. P. Metc-'lf (rch): tcbcco flea beetl, is crr- n tly
starting earlier this year than last in eastern North Carolina.

J. U. Gilmore and J. P. Vinzant (March 23): in a 3-day survey
of tobacco plant beds in eastern North Carolina only a fe-.7 beds -.ere four
to sho%-i serious losses from flea beetle attack. Most cf the teds that
-'ere well covered with cloth were unaffected. The mtaimur infestation
was 40 beetles oer square foot of plant-bed arec.

South Carolina. W. A. Shands and N. Allen (March 17): A survey throu-h north-
eastern South Carolina showed the flea beetle to be causing economic
losses in tobacco rlant beds in Florence, M'-rion, and Horry Counties. The
most severe injury was found where the plant beds were ecrly constructed
or where the canvas did not properly cover them. In one instance of
severe injury circumsta-nces indicated that hibernating beetles ,are car-
ried to a plant bed in pine needles that .:ere used to nrot2ct the prlants
from cold weather.

F. Sherman (March 29): The tobacco flea beetle is seriously
abundant in the eastern part of the Stat,

..... ; JU`7E BEETL7E (,ctinis nitida L.I

North Carolina. J. U. Gilmore and J. P. Vinzant (March 23): One tobacco plant
tei of 150 yards in Pitt County, in eastern North Carolina, had sustained
a loss of 50 percent, owir. to attack by larvae of the reen June betle.
The previous cror, was s'eetpotatoes that had produced luxuriant growth,
providing suitable conditionss for June be etle J- deposition.

COTTON N I N SE C T S

PINK BOLL7:U'-.-. (Pectinophora gossypiella Saund.)

Texas. A. J. Chapman (February): An examination of infested cotton bolls in
the hibernation experiments at Presidio, in the Big Bend of Texas, indi-
cated that the mortality at the close of February this year (43.75 per-
cent) was about the same as last year (40.80 percent). Examinations
made on February 27 in a few fields in which stalks were standing indi-
cated that the winter had caused little mortality.

THURBERIA 7EEVIL (Anthonomus grandis thurberiae Pierce)

Arizona. W. A. Stevenson (Mn.rch 13): At Tucson, in southern Arizona, the
first Thurberia weevils from infested cotton bolls that were plowed
under and irrigated on February 5, began to emerge last week. This is
a few days later than the first emergence of this type of weevils during
the last 2 years. Several Thurberia weevils were out of their pupal
cells on Thurberia plants on March 11 but, as the plants have not begun
to bud, these weevils will undoubtedly die before food is available.

FIELD CRICKET (G-ryllus assimilis F.)

Mexico. C. S. Rude (March 23): Crickets are very numerous in the fields at
Tiahualilo, in the Laguna. The most common species is G. assimilis.
When the cotton begins to come up the species may do considerable
damage.

COTTON FLEA HOPPER (Psallus seriatus Reut.)

Texas. F. L. Thomas (0&rch 26): Cotton flea hop-pers began hatching in
small numbers at College Station, in south-central Texas, on March i1
and were found in the fields shortly afterwards. On warm days, about
the 22d, many hatched in the cages.

'A:M'r:7ETORMS (Geornetridae)

New Jersey. M. 2. Leonard (March 21): Cankerworms, mostly Faleacri'ta
vernata Peck, were observed in considerable numbers ascendinr.- trunks
of oaks and other woodland and shade trees at Ridgewood. The worms
were matins freely.

TE::T CATERPILLARS (Malacosoma spr.)

Vermont. H. L. Bailey (M.Lrch 26): Egg masses of forest tent caterpillars,
(M. disstria Hbn.) ar.- abunrir.t in Tindham, Windsor, and Rutland Countie's,
southern Vermont. Scouting records show an aver?,); of from 5 to 20 e:T-;
masses vc-r tree.

Arizona. C. r. Lebert (March 16): Small webs of MIlacosom2. sr. were ob-
served on cottonwoods north of Phoenix. The trees are scarcely in leaf
at this date. A few webs were found on a crab apple tree in this same
area. The caterpillars had done no damage.

S{ITE-VJLR'cP ..TUSSOCK MOTH (Hemerocamna leucostigma S. & A.)

Illinois. W. P. Flint (March 23): It is practically impossible to find
tussock moth eggs anywhere in the northern half of Illinois. This is
probably because the severe winter of 1935-36 killed nearly all of the
eT-z above the snow line.

BOXEL=ER

A BOXELDER LEAF ROLLER (Cacoecia negundana ryar)

Colorado. S. C. McCa'npbell (March 16): Eggs of the boxelder leaf roller
(Archips negundana Dyar) are more abundant than for m r,.y years and have
come through the winter in viable form in Weld3 County, north-central
Colorado.

C. R. Jones (March 26): In towns in northern Colorado consider-
able dormant spraying is being done on boxclder and cottonwood tre-s
for control of the boxelder leaf roller.

ELM

EUROPEAN FRUIT LECA" iU!T (Lecanium corni Bonche)

Oklahoma. F. A. Fenton (March 20): ThE. infestation on elms in many localities
in the State is serious. Males are emerging and female scales are about
one-third developed at Stillwater. One s-,- ies of arlrasite has been
reared. Th2 rpcrcentage of parasitization of scale ar ears to be quite
high.

ted in the village of Freeport, Long Island, though relatively few living
insects were to be found on the above date.

P I NE

WOOD BORERS (Ios spp.)

Pennsylvania. R. M. Baker (March 24): Pine trees have been severely injured
by drought during the past few years. As a result, many inquiries have
been received concerning borers, usually Ip.s spp., which infest these
weakened trees. Most plantation owners blame these-secondary borers for
the death of the trees.

KAN2UCKET TINE SHOOT MOTH (Rhyacionia frustrana Comst.)

New York. E. P. Felt (March 25): Specimens of the work of the Nantucket
pine moth were received from near Hempstead, Long Island.

Georgia. 0. I. Snapp (March 22): Infestations by Fiorinia theae Green,
Parlatoria re 'nvii camelliae Comst., and Lepidosaphes camelliae Hoke,
on camellia bushes, mostly Camellia japonica, are unusually heavy at
Fort Valley. (Det. H. Morrison.)

Mississippi. C. Lyle (Mrrch 24): Scale insects, F. theae, reported from
Port Gibson, Centreville, and Laurel, and L. camelliae on Camellia
japonica from Centreville, all in the southern Dart of the State.

cedon, one of the brush-footed butterflies, was found feeding on bushy
pentstemon at the Boyce Thorn- sen S. W. Arboretum at Superior, south-
central Arizona. Every bush in the cnyon was covered with the cater-
pillars, which were rapidly defoliatin, the plants.

TROPICAL RAT MITE (Liponyssus bacoti Hirst)

North Carolina. Z. P. Metcalf (March): Reported in Wake and Robeson Counties.

G. B. Lay (i-1rch 24): Specimens of the tropical rat mite were
collected in a house at Raleigh oh.February. 12. This collection was made
following an investigation of the occurrence of three cases of endemic
typhus in Raleigh....
SAiNDFLIES' (Culicoides sp.) )

Georgia. J. B. Hull (March 2 4): Notwiithstanding the unusually warm weather
S during the middle of February, no sandflies have been observed biting
in the vicinity of Savannah.

Florida. S. E. Shields (February 29): Sandflies have been present in annoy-
ing numbers on the island east of Fort Pierce, on the eastern coast. A
few complaints have been received from the mainland.

BLACK WIDOW SP zEP (Latrodectus mactans F.)

Maryland. E. N. Cory (March 15) ,.Found in a basement in Salisbury, on the
Eastern Shore.

Kentucky. W. A. Price (March 26): A female black widow spider was found at
Lexington on Marchi 22.
CATTLE

SCPEWW ORM (Cochliomyia 'mericana C. & P.)

United States. W. .E. Dove (April 1): At the end of March screwworms were
confined principally to the overwintering areas of Florida and southern
Georgia and to that portion of Texas south of U. S. Highway 90, which
runs from Ornnge County, on the east to Del Rio, ValvVerde County, on
the west. In Florida the low 'ooint of the winter was experienced dur-
ing the last wveek of December, when 194 cases were reported from the
entire State. Since then summer temperatures permitted the pest to
build up'in dry swamps where wild hogs were infested and when cases
occurred in navels of young animals in other areas. In Florida the
number of cases reported for December was 1,663; for January, 3,213;
for Februairy, 3,573; and from March 1 to 26, 2,930. Cases are now
most numerous in navels of young calves and the infestations are rather
gener lly distributed over the peninsular portion of the State, with a


-64-








lower incidence in the more northern counties. During January specimens
were identified from Georgia as Cochliomyia americana C. & P. from
Brooks and Lowndes Counties on the southern border in the central part
of the State, and Effinrham County, on the Georgia-South Carolina State
line. During the third week of February screwworms were again identi-
fied from Brooks County. The situation in Florida differs from that of
last year in that the low point occurred during the last week in Decermber
for last winter and during- the third week in February for the preceding
winter. At the present time screwworms have a hi:'-"ir incidence and are
more evenly distributed in Florida than they were at this time last year.
In Texas the situation is somewhat encourai-ing in that shearing of goats
advanced ahead of the spread of the pest so as to prevent a build-up
from this source-. Cnses are present, however, where shearing of sheep
is now getting under way and efforts are being made to prevent build-
ing up a large population of the pest in such injuries. As yet screw-
worms have not been found in localities west of Del Rio, Te:x., or in any
of the other Southwestern States. A few, cases were found in the canyons
of Uvalde County, but there is yet no evidence that they are present on
the Edwards Plateau. At San Antonio one local infestation was apparently
stamped out. Counties near the Rio Grande between Del Rio and 5:"r'7ns-
ville, Tex., show the greatest number of cases for the winter months, as
well as for March. For all counties in southern Texes there 'ere re-
ported for December 1,121 cases; for Janua.y, 675 case,-,; for February,
29S cases; and from March 1 to 26, .1,560 cases. Durin: the last week
of March 469 cases were reported, as com-o-red to 595 during the pre-
ceding week. Stockmen in Texas are screws'orm conscious and are prevent-
ing a build-up of population of the pest in y~.un. animals born during
this season.

T cx:. E. F. Knipling (:'-.rch 24): Ranchmen in Hidal" o County, in th
southern tip of Texas, report increased activity of the scre'.r7orn fly
during the last week of February. Th-- most common infestations were in
the navels of your.:, calves. Only a few cases were reported during the
period from January 1 to the end of February.

A. W. Lindquist (Ma.rch 24): No infestations of -nimwls were observed
in the vicinity of Uvalde from January 16 to February 28. On M-Lrch 1,
two sheep and one calf were found to be infested.

W. L. Barrett (March 24): A survey of the a bund-nce of C. americana
along the lower Rio Grande indic.?tt-s that the flies were more numerous
*along the Rio Grande from L-redo, in Webb County, to Rio Grande City,
in Starr County, during the period from January 15 to F7.bruary 15. Cnn-
tinuing this survey west to Pr-sidio, from March S to 1?, no flies or
screwworm cases were found west of Dil Rio, Vr'l Verde Crunty.

Arizona. C. C. Deonier (Mairch 20): In a surv .,- on Ma.rch 20, f';ur crises -f
screw ..orIns were reported from the Arizo,)n -Mxic- lin 30 mil"s west of
Nogalfs, near the central part of the- State.








CATTLE GRUBS (Hypoderma spp.)

Georgia. E. R. McGovran (March 24): An examination on February 5 of 10 cat-
tle showed 6 carrying 75 grubs. Four animals did nnt show infestation.

Iowa. R. W. Wells (March 24): An examination of several hundred head of dairy
cattle in the vicinity of Des Moines on March l14, showed that none of
these animals carried more than 6 or 7 grubs, and less than 10 percent of
them were infested.

Missouri. L. Haseman (March 24): Throughout central Missouri ox warbles
generally are less abundant than they have been during past years, al-
though snme cows have been showing heavy infestation. Most of the warbles
thst have not been killed have left the cattle.

Texas. E. W. 1aake (March 24): An examination of 131 dairy cattle in the
vicinity of Dallas on March 1-2, showed that 88 animals, or about 67 per-
cent, were or had been infested with cattle grubs. Of the 275 larvae
that had infested the 88 cattle, approximately 94 percent had already
left the anir.mals.

BUFFALO G'TATS (Eusimulium spp.)

Mississippi. G. H. Bradley (March 24): In northwestern Mississippi buffalo
gnats were causing considerable annoyance orior to February 27. An exam-
ination of the Yalobusha River showed the presence of large numbers of
young larvae, but very few grown larvae and no pupae were found. The
onset of cold, rainy weather on Fcbruary 26 apparently prevented annoy-
ance in the Mississippi Delta during that week, but reports indicate that
the pests had been abundant. Examinations of the rivers indicate that
the gnats are still in the larval stage, as few pupae or pupal cases were
seen on the vegetation and trash in the streams. The rapid fall of the
rivers in this section since the flood probably caused the stranding of
many larvae in quiet back waters. Reports indicate thn-t little trouble
from the gnats had been experienced in Coahoma and Leflore Counties.
From Ma1rch 11 to 14 the gnats were very bad in Tallahatchie County and
work stock required repeated treatments with repellents to prevent
severe annoyance. Unfavorable weather during the week of March 19 ap-
parently prevented serious annoyance.

C. Lyle (March 24): Buffalo gnats have been reported at
intervals during the past few weeks from several points on the Delta.
An unconfirmed report of gnats in Neshoba County in central Mississippi
has also been received. The outbreak thus far has not been severe.

Arkansas. M. W. Muldrow (March 24): It was reported that buffalo gnats made
their appearance in eastern Arkansas in January and small numbers were
noticed from time to time throughout that month and February. On March 18
they appeared in such numbers as to be extremely troublesome to work stock
in a large part of Monroe, Saint Francis, Lee, and Phillips Counties.
