..e wish, at this time, to express, our thanizs to our collaborators
for the excellent cooperation they ,.:ve us last year in the collection of
hll_.-.,: c_ adults. We hope to cotitnuo this wor: durig-- the coming yCecr and
should appreciate receiving adults from all of our collaborators. We also
wish to call your attention to a mineographed publication (.-33!-) on the
periodical cicada. In this circular we hvve recorded -the 1ocalitios wheree
Broods X and XXII appeared in previous -years. We shold a ecite an data
on places of appearance this y':r.

Despite the very severe winter that prevailedd over most of the W:.,-.t
Belt, reports from Indiana, Ark.7ansas, and O'o indicate that the hessian
fly suffered but little mortalityo On the othe.. hand, the chinch bug in
L.diana suffered severe mortality, wvich ran from 49 to 9S percent in parts of
the State.

The corn ear worm wvs prevalent "during January in ext.e south-
eastern Texas.

The alfalfa weevil vas reported ,s prevalent in the San Francisco
Bay dCistrict of California, and 1-- tIe i,. dle o" Fcbruary parasitization by
Bathyplectes was running over 50 percent.,

One of the most im'portart sugarcane mites, T"-r son emus -cft i
IM.ichael, .1 s been found established on the eastern edgeC of the EverFlades in
Florid.

Reports from Virginia indicate that te rosy a).e .ill be
more numerous than usual in the southern Appalachian orle-gro'.ng districts
this '-ar.

Several small infestations of California red scale continue in the
Phoenix area of Arizona and an -- icatio car.ign is under way.

The vegetable weevil was numerous enough in the Gulf region and
Georgia to attract considerable attention.

The banded cucumber beetle ""'::s reported to be attaching a number of
truck crops in Florida, Al-.bama, and California.

Reports from the South Atlantic and Gulf States indicate that the
boll evill has been less active during the late w-inter "Lan for many years,

During JaEnr-.-:' ry screw worm population "-as, in general, very low;
however, a minor outbreak occurred in U.%-,e C -unty, Tex., where rather
serious infestations were found on rec ly do c d shcep.










CEREAL AND FORAGE-CROP INSECTS


HESSIAN FLY (Phytophaga destructor Say)

Indiana. W. B. Noble (January 20): Apparently most of the late fall brood
succeeded in completing their growth and forming puparia. Volunteer
wheat taken from the field today showed only about 10 percent still in
the larval stage. These larvae were from half grown to mature and were
apparently still alive. (February 17): Dissection of puparia ta':en from
volunteer wheat in a field near La Fayette on February 8 showed practic-
ally no mortality, notwithstanding severe weather. Many of the larvae
they contain are now pupating in the greenhouse.

Missouri and Kansas. E. T. Jones (January): A survey early last NTovember
indicated that a moderate though potentially important infestation in
southeastern Kansas and southwestern Missouri had developed from second-
brood hessian flies over an area where infestation by the first brood
was comparatively light. The larvae wore from half grown to full grown
and later developed into second-generation apuparia.

Arkansas. Dwight Isely (February 29): For many years hessian fly was not
considered a problem in Arkansas because so little wheat was grown.
During the past few years, howevc', the wheat acreage has increased
considerably, owing to removal of other crops from the land. Much of
this wheat has been sown early for pasture. Practically all of the
early sown wheat in Washington County (in northwestern Arkansas) is
infested. In some fields 50 percent of the plants are dead and the
others are infested.

Okh.!?homa. F. A. Fenton (February 29): A few observations made last fall in-
dicated a heavier infestation than for many :-ears. The infestations are
apparently scattered, but occur in Garfield County in the heart of the
wheat belt of the State; however, we do not anticipate serious damage
in the State this year.

CHI.TCH BUG (Blissus leuco-)terus Say)

Indiana. C. Benton (February 18): A mortality of 49 percent, evidently
due to the severe winter, was observed in a total of 1,448 chinch bugs
present in 25 sainmples of bunch grasses taken in Tippecanoe County on
February 10 and. 1-. In two samples from exposed situations the mortality
was 9S percent.

Oklahoma. F. A. Fenton (February 29): The past winter has been marl:ed by
longer periods of colO ', .ether than 7,ny winter for some years. General
observations indicate that it lhas hadC no serious effect on the chinch
bug. Records taken by students show an average of 14 chinch bugs per
square foot on the college farm at Stillwvater, the range being from 20
to 267t these records -iere taUen in the most favorable type of hiber-
nating quarters that we could find, i. e., in a good bunch-grass vicinity











that had been in Sudan grass last summer. It is a-' parent that there
are lore chinch bugs in hibc-nr- tion than there were a ye.r aro.
C0aii

CORNT EAR ORi.: (Heliothis obsoleta Fab.)

-Xa.s., T. C. Barber (January): The corn ear w.orm 7ias. frequently found in
corn in January in the vicinity of Bror'nsville, though it was not ob-
served on cotton during the month. The corn was planted late in the
fall for the winter crop. Larvae of all sizes are present and pupa-
tion is talking place in the inectary,

ALFAJCA

ALFALFA '..'VIL (Hy-oera *ostica >1.)

California. A. E. MIichelbacher (Febru ry 22): Larvae cndu adults could be
collected throughout the fall an 'i- inter in midle lowl-, Cali ornia.
They were most abundant in uhe San Francisco Bay area, where Ic Janu-
ary, 17 as high as 28 larvae were collected to 100 s'reeps of a net.
On the 2Lth of January the count juped to Q5 and on the 30th to 132.
On the 10th of Feb.rury the count rei-i".,edabout the same, but about
one-fourth of the larvae w'ere dead. tther t-is '-'as the result of
weather conditions or of a ungus has not yct been determined. In
the northwestern part of the San Joaquin ValleyI larvae and adults
were collected v;ith ease. On t-Ie 24th of J::..ary as high as 15
larvae and 15 adults were collected to 100 s'csps of a net. This is
the earliest I have tahen the w-eevil in this .- :. On the 17th of
January adults of the parasite Bath>: t'Les crculionis Thorns.
could be collected. Parasitization of the alialfa evil larvae,
however, was not high. In one field in the San Francisco Bay area
5 larvae out of 26 were found to be p, iti.ed. rlile in another
6 out of 34 were p-.: sitized. Adult p-..asitc -,er. _ntul, but on
the 24th of January only 37 alf-,lfa wcevil ..ve ot of 308 .'..:re para-
sitized, and on the 30th of January in one ficid 33 alfalfa weevil
larvae out of 213 were parasitized; in another, 13 out of 4l were para-
sitized; ad in a third field 25 larvae out of 63 -ere parasitized.
On the 10th of February 116 larvae out of 192 were parasitized, while
in a second field 40 out of 52 were parasitized. Up to the present
time some fields have consistently shown higher parasitization than
others. In all instances, however, the parasitization increased
rapidly as is indicated by the figures given above, The extent of
Sparasitization was obtained from rearing records--thit is, large alfalfa
weevil larvae were brought into the labors tory and the extent of
pal-asitization was determined on the number of alfalfa weevil cocoons
containing cocoons of the parasite. A surprising number of the
parasite cocoons are the dark-colored, over-intering form, and I
suppose months will elapse before adults 'ill emerge from them.
Overwintering cocoons obtained from alfalfa weevil larvae collected
during the latter pert of .Ia-Y 135 were placed on a window sill having


-7-









a northern exposure. Emergence started about the 10th of January,
has continued to be heavy, and is about completed.

CLOV2R LEAF 7I:JCVIL (Hyoera -ounctata Fab.)

California. J. C. Hamlin (February 4): Sam-)ples of larvae collected by
G-. G. Schv'eis near Sacramento were determined by A. G. Boving.

A. E. I'iichelbacher (February 2-24): The clover leaf weevil
"*!-s found generally throughout the alfalfa fields.

ALFALFA LCOPE (AutoRrrha californica Speyer)

Celifornia. A. E. lMichelbacher (Februpry 2".): In checl-:ing through alfalfa
fields during January and the first pert of February, I found the
larvae of the alfalfa semilooper quite com.icn. :r.n7 of them were para-
sitized by a tachinid.

SUGAS.CAM ,

SUGARCATj BOR3R (Di,':;raer saccharalis Fab.)

Louisiana. B. A. Osterborgor (Fecbruary 24): Larvae of the sugarcane
borer hibernating in cdry corn staJ.:s shlio an increase in mortality,
but among those in the stubble of volunteer corn a few live larvae
are found. The mortality from the cold is not so high as it was
last season.

SUGA:,CACK ROOTSTOCK W7EVIL (Anacentrinus subnudus Buchanan)

Louisiana. B. A. Osterberger (Fe bruary 24): Adults, larvae, and pupae
were found in about every variety of sugarcane examined. Injured root-
stocks ranged from 30 to 67 percent.

A '.ITE (Tarsonemus bancrofti Mlichael)

Florida. P. IT. Annand (January 29): Word has recently been received of
the discovery of T. bancrofti on sorgiuu hybrids and New Guinea canes
in four locations on the experimental plats rnintained by the United
States Depsrtment of Agriculture at Cc.ial Point, on the eastern edge
of the Everglades. An infestation w.s also found in an adjoining
field of commercial cane. Owing to the rather general occurrence
of the mite, it is feared that its eradication may prove to be
difficult.











FRUIT INSECTS


APPLE

CODLING MOTH (Caroocapsa 'omionella L.)

Georgia. C. H. *Alden (February 19): The rint r carry-over of hibernzti.
larvwe of the codling roth is moderate at Cornelia'. Practically n:nu
have been killed by winter tempcnrturcs but sokie are dead from fungus.
Oregon. D. C. 1:0te (February 25): 3. G. Tho'.-pson reports that at the last
cxan.ination the larvae w-ere coming through in good condition.

ROSY APPLE APHID (Anuru. -is ro-eus Baker)

Virginia. W. J. Schoene (February 2U): Lcst fall returning migrants of the
rosy aphid were found in numbers on a-iplc foliage in m-any sections of
the State, and during the winter aphidc egEs have been observed to be
more numerous than usual. Accordingly, ;rowers are showing considerable
interest in the aphid spray. We expect this to be a rosy-aphid year.

SAN JOSE SCALE (Aspidiotus oerniciosus Comst.)

Georgia. 0. I. Snapp (January 2)): 7'-e San Jose scale is more abundant
than usual on p'%ch trees at Fort Valley. The percentage of living
sc-.le on unsprayed peach trees in Janua:-y vzs lower than that of anr. aver-
age year,which may be due to the unusually cold w.inter. Of 30,600
scale counted under the binoculars during the period January 14 to 24,
23,16g, or 75.7 percent, ''ere foundL to be alive.

C. H. Alden (February 19): Scale was very bad on peach and apple
at Cornelia in the fall, but sprayin and e:trer.el- severe winter
weather have greatly reduced the u:.b rs and. have prevented breeding.

Albba-a. J. M. Robinson (February 25): San. Jose scale is moderately
abu:dant on fruit treos at Auburn, Grand Pay, ara some other places in
the State.

PEACH

PLUM CUTCULIO (Conotrachelus nJe. ir FTbst.)

Georgia. C. H. Alden (February 19): Plum curculio still in hibernation
at Cornelia.

PEACH BORER (Aoer a exitiosa Say)
-i tree e o-rer -.-. os lr tl
Alabaa. J. 1%. Robinson (February): The h tree brer .s moderately
abundant at Auburn, requiring treo r..nt.









GKE7Ti PEACH APHID (Myzus persicae Sulz.)


California. E. 0. Essig (February 26): Because of the mild winter, aphids
have survived, in considerable numbers in the San Francisco Bay area.
The green peach aphid has been abundant at Berkeley. Adults of the
black peach aphid (Aphis persicae-nirer Smith) have been noted on
peach trees that have held their leaves all winter.

RAS.IBEERRY

RASPBERRY CALVE BORER (Oberea bimaculata Oliv.)

Utah. G. F. Xnowlton (January 10): The following letter was receiitly re-
ceived: "While pruning raspberries I noticed some of the newr canes
fell over. On examination, I found" in various canes, but principally
in the weaker ones, larvae rninj from about 3/16 to inch long.
The smaller ones were white, whereas the larger ones were dull white
with dark heads. The larvae entered anLd worked in the canes from 1
to S inches above the ground."

GRAPE

GUAPE LEA7HOPPER (Erythroneura comes Say)

California. S. Locc-rood (February 25): The grra- leafhopper was over-
wintering in considerable numbers in secUtions of the San Joaquin
Valley. Reports state that the excessive rainfall of the last 2 weeks
has apparently reduced the nueiers m,. :.edly.

PECAN

OBSCURE SCALE (Chrysomphalus obscurus Comst.)

California. M. L. Jones (February 25): The foci of known infestations in
California are limited to Pacoima, Los Angeles County, ,nd the vicinity
of Flinn Springs, San Diego County. The infestation is found only on pecan
trees.

WALIt3T

FROSTED SCALE (L-caniui oruinosurm Coq.)

California. H. J. Ryan (February 21): Infestations on English walnut trees
in the Por onz. district became so severe during the winter that about
250 acres of walnut orchards were sprayed 'rith oil in Janiary. This
scale has been well established for :..Pny years in southern California,
but this is the first record of any build-up to population requiring
treatment.








-l-


C ITRUS

PFRUIT FLIES (Anastrepha spp.)

Texas. P. A. Hoidale (January): All species of fruit flies found in the
Rio Grande Valley previously were trapped in increased numbers there
during January, The total for this month over December for Anastre-
p~ha ludens Loew jumped from 8 to 49; A. _e cnti:. Wied., from 43 to
76; A. fraterculus auct., frao 9 to 15; A. sp. "Y", from.7 to 30;
A. pallens Coq. from 48 to 5gO; and Toxotry,,panna curvicauda Gerst.,
from 11 to 26. Two specimens vhich have been listed as probably
neo'. species were also trapped. No larval infestations ,ere found
throughout the month.

MEALYBUGS (Pseudococcus sapp.)

California. H. J. ryan (February 21): OccasiocL- infestations of P. mari-
tirms Ehrh., and P, citri Risso still require liberations of the
ladybeetle C__rytolasms motrouzieri lulls. Control of 2. jahani
Green has been maintained. by the parasites CoC-2o ig urneyi
Compere and Tetrs.c-.Ers oretiosus Tiib.

A SCALE IiTSECT (Le-,idosa-hes halli Green)

California. 1. L. Jones (February 25): Surveys are in progress to estab-
lish the possible distribution of SIalll scale in the Chico district
of Butte County. To cate, all evidence indic-tes that it has not
spread from the United States Plant Introduction Garden. Eradication
of this scale during one season v..s attempted in the snprinn; of 1935-.
The only survivors found to date were four individuals on one tree.
The group containing this tree is isolated and has been given a very
drastic treatment. All stone-fruit trees leaving the station, about
3,600 in number, have been treated by vacuum funmi!aticn.

CALI01C7IA RED SCALE (Chryf7o:rnhalus aurantii Mask.)

Arizona. C. D. Lebert (February 24): Appro-::mately 10,000 citrus trees
are being fumigated in the Phoenix area. It is hoped that complete
eradication of this pest will be achieved.

GREEN CITRUS APHID (Afhis sniraecola Patch)

Florida. J. R. Watson (February 24): The first part of the winter was
very dry. Since then it has been cold and vwet. These conditions
were very unfavorable for the development of the citrus aphid, as there
was no food in the early part of the winter and it h's been too cold
for rapid development since. Aphids ,re at present about as scarce
rs I have ever seen them.

weevil. Larvae were found on turnip at Griffin, Orchard Hill, Milner,
and Barnesville, but none at Experiment. Larvae were collected at
14 of 24 properties visited. iTo serious injury was'observed. On
December 12 larvae were sent to me from Clarl2ston, De Kalb County,
on Chinese cabbage. (February 20): Vegetable weevil larvae, appar-
ently of the second and third instars, were found in turnip crowns
today near LUilner.

citrus groves in the north Phoenix area.










GARDEN CENTIPEDE (Scutigerella immaculata Newp.)


California. S. Lockwood (February 25): The lowlands of the Sacramento
Valley have been inundated for several cleys. It is believed that if
the water is not pumped out too soon, the asparagus fields will be
rid, to a degree at least, of the garden centipede.

A. E. Michelbacher (February 24): In checking over some
infested fields in the delta areajof the Sacramento and San Joaquin
Rivers, I found a marked reduction of the pest in several places.


TOI ATO

A CHIROIOMID (Spaniotoma sp.)

Ohio, J. N. Knull (January 15): Numerous tomato plants in a greenhouse
at Lancaster were infested with chironomid larvae, probably of the

young plants to break and wither,

OlNION THRIPS (Thrips tabaci Lind.)

Virginia. H. G. Walker (February 28): The onion thrips was found to be
seriously injuring young tornato and celery plants in a greenhouse at
Norfolk. Apparently the thrips had been breeding on cucumber vines
and when the old vines were removed and replaced with youn, tomato and
celery plants, large numbers of the thrips transferred their attention
to them an,. caused serious injury before their presence was-detected
and control measures were applied.

Texas. F. L. Thomas (February 26): Onion thrips are beginning to increase
in numbers in the Winter Garden district. The infestation is much
lighter than in 1935 at this time, averaging less than 5 per onion

SOU'TTEF2; A.i2Y'UOP.l (Prodeuia eridania Cram.)

Florida. J. R. Watson (F'ebruary 24): A heavy infestation of the semi-
tropical armyw:vorm occurred on celery in the Sarasota and Sanford districts.
The insect worked like a cutwoinn, go-.jirng out and ruining the stalks at
the base. The infestation has largely subsided, although a few indivi-
duals are still present.

SWETPOTAT 0

SY'ZTPOTATC 'J.-VIL (Cylas formicarius Fab.)

Florida. F. S. Chamberlin (January): !During the year 19334 an outbreak of
the sweetpotato weevil occurred in the noL'thrn part of Gadsden County.
Eradication methods were employed for a short time. Reports noiv indicate
that the insect is booming well established within a snall area, and one
field of potatoes has been reported as a total loss because of it. This
pest represents a potential menace in this section, where sweetpotatoes
are among the important crops.

Florida. J. R. <>atson (February 24L): The pepper weevil, which was found in
Manatee County last yeqr, has not been seen since August. Complete des-
truction of all the peoper fields during the sum-ner is undoubtedly res-
ponsible for this scarcity and possible elimination.

dant in the fields. They wore forced to go into hibernation without
food after the middle of 1Tove-iber.

Louisiana. 2. C. Gaines (January): A few weevils were active in the hiberna-
tion cages at Tallulahi until January 17, but there was no activity after

being characterized by hot Jays above average and cool nights below
average. Most of the ranchren reported more or less screw worm trouble.
One man had 26 cases in 100 docked sheeo. Five collections from these
showed C. americana, and probably all cases were of this species. A
rEncXTun-i near Rio Frio reported that of 41 docked sheep, 25 were lost
because of screw worm attack. Some of the cases observed were very bad,
harboring from 1,000 to 2,000 C. americana larvae and many eggs. At
Sonora and 1.enard, about 150 miles north of Uvalde County and at a
considerably higher elevation, no screw worm cases were observed in

noticed in flight from a steam-heated building in Baton Rouge.

Oklahoma and Texas. J. A. Beal (January): R. tibialis Bks. has done a
great deal of damage during the past summer to nurseries it Oklahoma
and Texas. This damage was peculiar in that it was not associated
vith buried wood or seedbed frames, but occurred on the roots of
seedling hardwood trees, in cultivated rows, often where the soil
appeared to be almost free fra rotting vegetation. Injury has been
most severe to green ash, mulberry, hackberry, and ioneylocust
seedlings, although almost no species showed irmmunity. In some nurseries
it is estimated that losses during the growing season ran as high as
25 percent.

NOTES FROM EGYPT, DECEMBER 23, 1935,
by
A. H. Rosenfeld


Recent survey has revealed that Pyrausta nubilalis Hbn. is
generally distributed' over Lower Egypt, extending as far south as Giza
Province (near Cairo). Investigations lead to the conclusion that four
generations occur annually in Egyp)t. Examination of individual infested
cornstalks at Damietta and Alexancric revealed from 10 to 12 live larvae
per stalk. In a number of cases Sesamii' sp. and Chilo sp. were found
feeding in the same internode with the corn borer and at times their
galleries were joined. In Alexanc'ria complete infestations may be found and
30-percent infestation iscommon.

The degree of infestation by Polychrosis botrana Schiff. in the
vineyards around Amria (Lower Egypt) last season averaged about 12 percent,
whereas the maximum damage reached 30 percent.

In a recent survey the long-winged form of mole cricket (Gryllotalpa
gryllotalpa L.) was noted everywhere in small numbers, but the short-winged
form (G. gryllotalpa cophta Haan) seems to be by far the most common and
widely distributed type, especially in Lower Egypt (Alexandria, Port Said,
Suez, and Ismailia). G. africana Bdv. was seen more particularly in the
Fayum (Middle Egypt) and in some parts of Lower Egypt, such as Dessuk,
Fareslur, and Iit Gamr.

NOTES TROCM PUERTO RICO


F. M. Vandenberg, of the Mayaguez, P. R., laboratory, reports that
in the investigations of the insects affecting corn recently undertaken
in Puerto Rico, the work of a dipterous r,,raot was observed in ears of green
corn. This maggot has been identified .s the young of a fly, Euxesta
stimnatias Loew. A closely allied species in this country is well known
as a scavenger. The Puerto Rican species, however, has been reared on
fresh green corn from egg to adult.

H. K. Plank sent in specimens of Cryptotermes cavifrons Bks. and
C. brevis ',all:., which were taken on Jainary 20 as they were flying
around lamps in a house at Layaguez, P. R. (Det. by T. E. Snyder.)
