Vol. 16 May 1, 1930 No. 3


Within the next fe7w &ays Brood X of teic periodical cicada
will be appering in the Northern States and Brood XXII will be
appearing in Louisiana and Mississippi. We wish to call the at-
tention of our collaborators to the desirability of our receiving
observations of this insect in as many definite localities as

During the latter part of April, the Mormon cricket began
hatching in enormous numbers in parts of Idaho and western Montana.

The army cutworm was seriously damaging alfalfa and small
grain in Oklahoma and Colorado, and cotton in parts of Texas. Cut-
worms were also reported from a nu.ib-:r of other States.

Several species of wiremorms were reported as appearing in
abnormal numbers in parts of 'Jashi.igton and the adults were re-
ported as damaging fruit buds in California.

Chinch bug flights were reported about the middle of the
month in Illinois. High winter mortality occurred in Oklahoma.

Considerable hessian fly infestation is reported from south-
eastern Kansas. The late fall brood ',s very materially reduced
by the severe winter, but the early fall brood ca.-i-: through the
winter with but little mortality.

Apple aphids are occurri:& in greater numbers locally in
the northeastern part of the country than for the last few years.
In the Pacific Northwest they are scarce.


The codling moth started pupating in the third week of the
month in, and adults were observed in Georgia thie middle
of the month. In the East Central States pupation started the
second week of the r.month and in the Great Basin was well under
way the third week of the jonth.

The eastern tent caterpillar wvas hatching in considerable
numbers throughout the Yew England, Middle Atlantic, South Atlantic,
and lower Mississippi Valley States early in April. This insect
appe' rs to be moderately abundant throughout this area.

Pupation of the oriental fruit moth was practically com-
pleted in Delaware during the month and adults were observed in
Virginia about the middle of the month. In Georgia, eggs began
litci.lling during the secon-1. week in April.

For the first time since the Japanese beetle has been
known to occur in the United States, this insect suffered consider-
able winter mortality in certain parts of the older infested areas.

The four-spotted tree cricket was damaging raspberries so
seriously in the Lewiston district of Iia"o that control measures
were necessary.

Cold, wet weather in the Charleston district of South Caro-
lina was followed by considerable injury by the seed corn maggot.
The tomato pinworm surviving the winter on old toato plants
is heavily infesting the new fields in the Santa Ana district of

Hundreds of acres of cabbage in Mississi-.)i were plowed under
on account of heavy cabbage aphaid infestations.

A heavy infestation of forest tent c?.terpillar was reported
from the southern part of MississipAi, sweet gum and oak being de-
foliated in four counties.

Larvae of Halisidota ingeiis Hy. Edvi. are seriously damaging
ponderosa pine in the Apache T.a.tional Forest in Arizona.




South Dakota. H. C. Severin (April): No ac>:s hatched yet out of doors.
Brought in some eggs from two areas, one covered by snow throughout
the winter, the other not so covered. Eggs in both lots have hatched
in approximately the same numbers and at the same time in the labora-

MORMON CRICKET (Anabrus simplex Hald.)

Montana. A. L. Strand (April 22): The warm weather of the past 10 days
has caused the hatching of Mormon crickets in large numbers in
southern and western Montana.

Idaho. C. Wakeland (April 21): Mormon crickets began hatching in the
districts near Boise March 15, and now are hatching in numbers at
Riggins in Idaho County and near Mountain Home in Elmore County.
After beginning to hatch they w"ere held in check for 2 weeks by cold
weather. The higher areas are later than normal and no hatching has
been reported in eastern Idaho, but in the warmer, lower areas enormous
hordes are now beginning to attack range vegetation.

CUTW7ORMS (:Ioctuidae)

Alabama. J. M14. Robinson (April 21): Cutworms are very abundant, attacking
vegetables, particularly during the last week of March and the first
week of April.

Mississippi. C. Lyle (April 24): Cutworms have apparently caused more damage
this spring than usual. Injury to cabbage, tomatoes, young beans,
and other plants has been general.

Iowa. H. E. Jaques (April 24): Many cutworm larvae are in evidence.

Kansas. H. R. Bryson (April 7): Cutworms (Chorizagrotis auxiliaris
Grote) are very plentiful in grass lands and wheat in Harper, Sumner,
and Bourbon Counties. HIost of them are army cutworms, but some small
variegated cutworms (Lycophotia margaritosa saucia Hbn.) are present.
Cutworms in general are not as plentiful as in the past two seasons.

Oklahoma. F. A. Fenton (April 20): The army cutworm (C. auxiliaris)
caused serious injury to first-year alfalfa and oats in Alfalfa

Colorado. S. C. lMcCampbell (April 8): We have received reports from most
of the counties of eastern Colorado of damage by C. auxiliaris;
however, we have had a snow or two every week and very cold weather.
(April 1S): We are being besieged with reports from northeastern


Texas. F. L. Thomas (April 22): On April 10 cutworms had destroyed
almost 60 acres of cotton in Brazoria County.

R. E. McDonald (April 20): Cutworms are reported as damaging
alfalfa in the southern end of the Mesilla Valley.

Utah. C. J. Sorenson (April 24): A few climbing cutworms are attacking
peach trees.

California. C. S. Morley (April 3): Cutworms appeared to be very plentiful
in vineyards in Kern County; however, all vineyardists used tanglefoot
on their vines and prevented serious, injury.

J. C. Elmore (April 2): Variegated cutworm (L. margaritosa
saucia) is common on tomato vines near ITiland, attacking fruit and
foliage. Losses are not unusually heavy.

MOTJjTIiTG-CLOAK BUTTERFLY (Hamadryas antiopa L.)

New Jersey. W. P. Better, Jr. (April 20): The first specimen of the
mourning-cloak butterfly in spring flight was observed at Moorestown
on March 15.

A CABBAGE BUTTERFLY (Pieris monuste L.)

Florida. H. T. Fernald (April 13): No evidence of migratory flight of
P. monuste ar yet at Orlando. Adults are scarce inland; slightly
abundant on the west shore of the Indian River between Indian River
City and Cocoa; ouite abundant opposite Cocoa across Indian River
(1 mile wide there) and increasingly abundant all the way out to the
outer beach (approximately 10 miles by road; perhaps 5 miles air
line). Abundant on eastern side near outer beach but without drift
in any one direction as yet.

WIREWORMS (Elateridae)

Waishington. M. C. Lane (April 20): At Prescott and Pendleton damage from
Great Basin wireworm (Ludius noxius Hyslop) is showing up to a
greater extent this year than normally, because of the extent of
winter injur. to wheat, resulting in a thin rn. weak stand.

M. 0. Lane and H. P. Lanchester (April 22): Adults of the
Pacific coast wireworm (Limonius canus Lec.), the sugar beet wireworm
(L. californicu Mann.), and the western field wireworm (L. infuscatus
Mots.) have been emerging and mating in unusually large numbers at
Walla halla. This intense activity resulted from the unseasonably warm
weather of the past 2 weeks which has materially shortened the normal
emergence period. Oviposition is taking place. Some damage by larvae
to potato seed pieces has been noted.


California. C. S. Morley (April 3): Click beetles were found doing slight
injury to young grapevines in theArvin district, Kern County.

R. S. Wagner (April 13): Adults of L. canus are causing serious
damage to unfolding buds of President plums grafted in 1935 to French
prune stocks in a planting of 80 trees in the Kings River bottoms near
Sanger. In iany instances the entire bud was eaten.

VHIIE GRUBS (Phyllophaga spp.)

Wisconsin. C. L. Fluke (April 20): NTo regular flight of June beetles has
been observed to date. Several specimens of P. tristis Fab. have been
collected at the ground surface during the few warm days of mid-April
and one was found the last of March in Dane County.

Alabama. J. M. Robinson (April 21): The bro-m June bug (P. micans Knoch)
has been emerging at night and returning to runways in the soil in
the morning. They have become pests around lights on porches and in

Georgia. G. F. Moznette and S. 0. Hill (April 14): Lir--e numbers of Aay
beetles have appeared in the vicinity of Americus and Albany during
the week of April l4 and have been quite abundant since. The beetles
have done considerable damage to the new growth on pecan trees.

T. L. Bissell (April 16): May beetles are now very abundant at
lights at Griffin. They were first noted on April 13. Feeding has
not been observed.

Mississippi. H. Gladney (April 24): May beetles are doing considerable
damage alonr the Mississippi coast to Japanese persimmons and pecans.

Louisiana. B. A. Osterberger (April 23): During the entire month June
bugs have been active on the warmer nights.

Kansas. H. R. 3r-'son (April 20): Population of white -rubs not so'heavy
as usual following the year of beetle emergence.

Texas. F. L. Thorns (April 22): On April l1 the first record of P.
submucida Lec. for the current season came from Dimmit County, collected
by S. E. Jones.

JAPANESE BEETLE (Popillia japonica ITewm.)

New Jersey. C. H. Hadley (April 23): Conditions during the winter of 1935-36
were such that for the first time since the beetle has been known to
occur in the United States there has been considerable mortality of
the grubs at certain places in the infected area, owing to the extremely
cold weather, couxled with lack of a sufficient blanket of snow.
However, the destruction of the -rub population in the soil is not
general or uniform throughout the infested area, but is most evident
in southern Iew Jersey and eastern Pennsylvania.


Pennsylvania. R. M. Baker(April 22): From 1 to 12 larvae per square
foot were found in grass roots in.'Cumberland County. No indication
that the winter had killed larvae. The snow was deep over this
section all winter.

COMMON RED SPIDER (Tetranychus telarius L.)

Virginia. H. G. Walker (April 21): The red spider continues to be
relatively abundant in some strawberry fields at Norfolk and-may
cause serious injury under favorable weather conditions unless
control measures are applied.

Mississippi. C. Lyle and assistants (April 24): Heavy infestations of
red spiders have been observed during the past 15 days on azaleas and
camellias at Moss Point. Red spiders are less abundant on camellias
at Poplarville than they were last month, but they are fairly
abundant on arborvitae in southwestern Mississippi.

Ohio. N. F. Howard (April 21>: Hydrangeas in a greenhouse at Columbus
were very heavily infested on April 4.

Kansas. H. R. Bryson (April 10): Large numbers of red spiders are
present in northeastern Kansas.

Idaho. C. Wakeland (April 21): Common red spider emered at Lewiston
on April 15, where it was feeding on young mustard plants.



CHINCH BUG (Blissus leucopterus Say)

Indiana. C. Benton (April 17): No flight from hibernation quarters
observed to date at Lafayette. Bugs were stirring in grass clumps
on April 14 when the maximum air temperature reached 770 F, but "on
exposure to sunlight showed a tendency to hide rather than to fly.
From 50 to 100 or more live bugs per clump of Andropogoni could be
found on that date.

Illinois. W. P. Flint (April 20): Flight was reported in central Illinois
for the first time this year on April 14, with heavy flight 'on April
20. There has been considerable activity in the cover and some
crawling out of the bugs from the overwintering shelters to nearby
wheat fields.

Ohio. T. H. Parks (April 24): A survey made in five north-central counties
shows an average of only two bugs per square foot of timothy clump.
This is from one-third to one-half of the niu.iber found last fall and
indicates a winter mortality of over 50 percent. From present indica-
tions, there will be no chinch bug outbreak this year in Ohio.


Iowa. H. Ei Jei.ques (April 24): The chinch bug is sufficiently abundant in
southeastern Iowa to threaten danger if conditions are favorable.

Kansas. H. R. Bryson (April 6): Not many chinchh bugs have been found in
clumps of grass at Wellington, according to E. G.* Kelly. Up to this
date none have entered the small grains. Very few bu-s found in
Bourbon County and in the vicinity of Manhattan, Riley County.

Oklahoma. F. A. Fenton (April 20): A spring survey from ivMarch 9 to 13
indicated that there was approximately 79.3 percent mortality of the
chinch bug in Oklahoma and that the mortality in sorghum stubble was
considerably greater than in bunch grass. An avera::e of 3.1 bugs per
square foot was found in sorghum stubble and 19 per square foot in
bunch grass.

C. F. Stiles (April 22): Conditions during the past month have
been favorable for chinch bug development.

HESSIA1I FLY (Phytophaga destructor Say)

Indiana. W. B. Noble (April 17): Pupation of the hessian fly in the field
began at Lafayette the last week in March. About 24 percent pupation
by April 15. There has been no eraer'-enc, to date. Apparently some of
the earlier formed pupae were killed by the abnormally low temperatures
early in April. (April 24): Field observations during' the past few
days give evidence of a very high winter mortality of the late fall
brood in the area e;tendinj front Attica east to the Ohio line--much
higher, in fact, than was indicated by earlier e:mninations. The
practical elimination of this brood substantially reduces the danger
of a severe spring outbreak in central Indiana. However, the early
fall brood in volunteer and early sown fields, "-hich reached the
puparium staTe well in advance of cold weather, suffered comparatively
little mortality and may still be the source of considerable spring

Kansas. H. R. Bryson (April 9): T-"-nty-five counties in southeastern
Kansas show considerable infestation. Some hessian fly "'as found last
fall in Bourbon County but very little this sprint. R. H. Painter,
in a survey of Geary,, MHorris, Chase, Lyon, Coffey, and Osere Counties,
found considerable variation in the infestations in these counties.
In Chase and iTeosho Counties wheat was heavily infested and a consider-
able amount of the wheat was killed by fly, wind, and dry weather.

FALSE WIREWOR1I[S (Eleodes spp.)

Nebraska. i;4. H. Swvenk (April 10): A Garden County correspondent reported
on April 10 that the spring wheat in that vicinity was being destroyed
by the plains false wireworm (E. opaca Say).

Kansas. H. R. Bryson (April 6): False wireworms seriously damaged some
wheat fields last fall near Conway SprinXs. E. G. Kelly reports four
Fields abandoned near Vellin;ton, and six at Anthony. E. suturalis Say
adult was taken and B. opaca was plentiful at Anthony.


A FUNGUS GNAT (Mycetophilidae)

Indiana. J. J. Davis (April 26): Fungus gnats have been exceedingly
abundant in wheat fields throughout central Indiana during the last
3 weeks, leading growers to believe that hessian flies were out in
unusually large numbers. Many growers were ready to plow up their
wheat fields, until they learned the true nature of the insects.


CORN BAR WORM (Heliothis obsoleta Fab.)

Louisiana. B. A. Osterberger (April 20): Slight damage has been noticed
by corn ear worm to young corn in St. Mary and Iberia Parishes.

Texas. R. W. Moraland(April 11): At College Station two eggs were found
per 100 plants on 1,500 plants of alfalfa and three eggs per 100
plants on 600 plants of Texas bluebonnet (Lupinus subcarnosus) examined
during the week. No eggs were found on L. texensg%.

SALT-MARSH CATERPILLAR (Estigmene acraea Drury)

Florida. J. R. Watson (April 23): Larvae were quite active in destroying
corn in Manatee County. It has been somewhat in evidence in watermelon
fields in Alachua County, but not nearly so injurious as it was 2
years ago.

CORN FLEA BEETLE (Chaetocnema pulicaria Melsh.)

Georgia. T. L. Bissell (April 21): Small field corn at Pomona, Spalding
County, is severely attacked by this flea beetle, with as many as 10
beetles to the stalk. There is much feeding on the leaves, which is
easily confused with frost injury.

SEED CORN BETTLE (Agonoderts pallipes Fab.)

Iowa. H. E. Jaques (April 24): The seed corn beetle, always quite abundant,
seems unusually so this year in the southeastern part of the State.


ALFALFA YLEVIL (Hypera postica Gyll.)

Utah. C. J. Sorenson (April 24): Adults of alfalfa weevil moderately
abundant in Salt Lake Valley,

California. A. E. Michelbacher (April 21): In the San Francisco Bay
area in two fields the avera-e number of larve collected per 100
sweeps of an insect net reached slir:htly more than 1,500, but no
economic damage resulted. The amount of 1?arasitization by
Bathyplectes curculioniz Thos. during this month has ranged from a
little over 50 to more than 70 p'-rc-nt. In the Pleasanton district
the greatest average nrLbcr of larvae collected to 100 sweeps was $32,

with most fields showing a much lower count. Here parasitization has
been close to 90 percent. In the San Joaquin Valley some very high weevil
counts were made. At Patterson on March 31 the average nuw-ber taken
to 100 sweeps was 5,890. In this field some economic damage was done.
On the same date near Vernalis one field showed an average count close
to 2,500, but no economic damage resulted. Throughout this area the
weevil population was the greatest yet encountered. Parasitization was
very low and ranged from less than 1 percent to nearly 10 percent. The
parasite has apparently become dispersed over most of the infested area.

LEAPeHOPPERS (C icade ll idae)

Louisiana. B. A. Osterberger (April 23):, Many. undetermined leafhoppers have
been found on alfalfa. Some yellowing of plants and girdling has been
noticed at Baton Rouge.

TARNISHED PLANT BUG (Lygus pratensis L.)

Louisiana. B. A. Osterberger (April 23): The tarnishbdplant bug has been
found in considerable numbers on alfalfa at the sugar station at Baton

Kansas. H. R. Bryson (April 20): The tarnished plant bug is quite numerous
at :iManhattan.

A CAIE FLY (Tipula cunctans Say)

Kentucky. W. A. Price (April 25): Leather jackets (T. cunctans), 40 to the
square foot, were found in a field of lespedeza at Mayfield. This
field had been in lespedeza 4 years in succession.


APHIDS (Aphiidae)

North Carolina. C. H. Brannon (April 25): Vetch in peach orchards over a
wide area in Scotland County is severely damL-. ed by aphids.


SUGARCANE 30E.E (Diatraea saccharalis Fab.)

Louisiana. B. A. Osterberger (April 21): On April 21 cane borer adults
were found at lights, and fresh eggs were collected at Franklin,
Jeanerette, and :7ev Iberia, but no Trichogramma minutum Riley have
been found in any of the borer eggs collected.


SUGARCANE BELTLE (Euetheola rugiceps Lec.)

Louisiana. B. A. Osterberger (April 23): Ligyrus is doing considerable
damage to the sugarcane in St. Mary Parish; Many "dead heart" stalks
are found attacked. Several of the larger sugar planters are using
trap lights in an effort to trap the beetle and some are employing
several men who dig for them around injured canes, paying so much per


TAmTISI'-D PLANT BUG (Lygus nratensis L.)

Virginia. W. J. Schoene (April 23): Tarnished
plant bugs were found very numerous in peach orchards in the Crozet
section, sometimes a dozen or more on a tree.

Washington. E. J. Newcomer (April 21): At Yakimnia very little injury to
fruit buds by tarnished plant bug has been reported, although bugs are
present in the orchards. Up to April 10 the weather was cold and
windy, which prevented activity. Since that time it has been unseason-
ably warm, and the buds have opened so rapidly that injury has been
confined to individual buds rather than to clusters.



Connecticut. P. Garman (April 23): Apple aphids, Anuraphis roseus Baker,
and Aphis poRi DeG., found in the field in New Haven County on April

New York. N. Y. State Coll. Agr. News Letter (April): In the Hudson River
Valley the am)ple grain aphid (Rhopalosiphumn prunifoliae Fitch)
started hatching March 25, the apple aphid the last 3 days in March,
and the rosy apple aphid between April 1 and 6. Infestation by the
grain and. rosy aphids may be somewhat heavier than it has been for
2 or 3 years. In the Lake district the grain and rosy aphids
commenced to hatch about the middle of April.

New Jersey. M. Kostal (April 9): The rosy apple aphid and the green apple
aphid were exceptionally abundant on expanding apple buds at Morganville
on April 5. The infestation indicates that it will be the heaviest
for the past 5 years.

Pennsylvania. H. E. Hodpkiss (April 23): Eggs of the rosy apple aphid began
hatching in A,?.ms, Berks, Bucks, Philadelphia, York, Lancaster, Lebanon,
Juniata, Fran?:lin, Dauphin, and Cuaberland Counties on April 1. In
Chester and Delaware Counties they were hatched on March 25 and 26. In
the east-central counties this species appeared on April 14 to 17. In
the northeastern area eggs had hatched between LUarch 31 and April 15.
The green apple aphid and the grain aphid were present on partly


dormant buds several days in advance of the rosy aphid. The green
apple aphid is the most abundant, the grain aphids not so abtmdant,
and the rosy aphid infestation of moderate intensity. kio aphids have
as yet hatched in the northern tier of counties. Syrphid eggs are
moderately abundant in all orchards.

Kentucky. W. A. Price (April 25): 'reen and grain aphids are now abundant
in orchards in the central part of the State.

Michigan. Ray Hutson (April 20): Aphids are hatching in southwestern
Michigan and the few specimens seen indicate that R. prunifoliae
is the predominant species.

Washington. E. J. :T.mwcomer (April 21): The various aphids attacking apple
seem to be very scarce at Yakima this sprinj7. It is probable that the
low temperatures (3 to 5 F.) occurring about the first of last
November interfered with the deposition of winter eggs, in the case
of the rosy and green apple aphids, and also killed most of the woolly
aphids (Eriosgoma lani:er=v Hausm.) that were above ground. The para-
site Aphelinus mali Hald., however, was not entirely killed out, and
adults have been emerging during the last few days.

SAN JOSE SCALE (Aspidiotus perniciosus Comst.)

Indiana. J. J. Davis (April 26): Winter mortality of the San Jose scale
has been very high, but in .n-, localities in the State where the 17-
year cicada is abundant, insecticide control lhas been advised because
the e,,- scars left by the cicadas will act as protective places for
the scales.

Michi an. Ray Hutson (April 20): Infestations are quite spotted. High
winter mortality- observed in the vicinity of Benton Harbor, Lansing,
and Muskegon. &pecimens from South Haven showed only normal mortality.

Idaho. C. Wakeland (April 21): Owing to ver-- cold weather late in the
spring and a sudden change to midsummer temperatures, little dormant
spraying was done in orchards and cherry trees broke into blossom
before dormant sprays could be applied. Undoubtedly this situation
will cause heavy increase of San Jose scale this year, for the insect
is known to have wintered successfully.

CODLIUG- MOTH (Carpocapsa pomonolla L.)

Delaware. L. A. Stearns (April 20):TwO percent of overwintered codling moth
larvae pupated on this date.

Georgia. C. H. Alden (April 21): The firrt codl .'- was caught in the
experimental orchard bait pots at Cornelia on April 16. To date only
g additional moths have been trapped. The weather has been too cold
for much moth emergence to date and there has been no egg" deposition.

Indiana. L. F. Steiner (April 23): Pupae of codling moth were first observed
by A. J. Ackerman at Zlberfeld, on April 10,and by S. A. Summerland at
Bicknell, 50 miles farther north, on April 13. 50 percent of 51 surviving
individuals found on and under trees at Elberfeld April 15 and 16 had
pupated, but only 40 percent of 43 found on April 23 at Bicknell had

Illinois. W. P. Flint (April): Pupations of codling moth started in
southern Illinois sometime prior to April l4, probably about the 10th.

Idaho. C. Wakeland (April 21): Codling moth larvae were beginning to pupate
at Lewiston on April 15.

Utah. C. J. Sorenson (April 24): In Salt Lake Valley 12.6 percent of 127
overwintered larvae had pupated on April 20 and 24.S percent of 326
overwintered'larvae were found dead in hibernaculae April 13 to 20.

Washington. E. J. Newcomer (April 21): Low temperatures of 3Oto 5 F. about
the first of last November at Yakima had no apparent effect on codling
moth larvae that were already established in cocoons for the winter, and
temperatures during the winter were not lo-. enough to cause any mortality.
Pupation has 'been taking place for some time and moths should be
emerging very soon.

EASTERN TENT CATERPILLAR (1alacosoma americana Fab.)

New England. E. P. Felt (April 24): The apple tent caterpillar has hatched
in southern New England, and its abundance in a number of localities
is indicated by the numerous small webs.

New Hampshire. L. C. Glover (April 25): The eastern tent caterpillar was
observed hatching in Durham on April 14.

Connecticut. P. Garman (April 23): Tent caterpillars are abundant in many
orchards in New Haven County, the larvae feeding on the unopened buds
in some places. Hatching began on April 4 but cool weather has retarded
their development.

New York. N. Y. State Coll. Agr. :,ews Letter (April): Eggs were observed
hatching the last of March and the first of April in the Hudson River
Valley, and by the last of April tents were quite numerous.

R. D. Glasgow (April 27): The eastern tent caterpillar was
hatching at ITew Rochelle on April 9, and at Albany during the past week.
This insect promises to be fairly abundant again this year in parts of
New York, even in some places where its great abundance during the past
2 years might have been expected to precede an abrupt decline to
relatively insignificant numbers.

Delaware. L. A. Stearns (MLarch 30): First hatching of eastern tent caterpillar
was observed on March 30 at lNewark.

New Jersey. T. L. Guyton (April 20): Eastern tent caterpillar is
numerous on apple and wild cherry at Bound Brook; also noted on apple
at Lebanon.

H. W. Allen (April 20): Eastern tent caterpillar not nearly
so abundant in Burlington County as during 1935. A moderate number
of tents are in evidence, but many clumps of black cherry have none.
Less abundant on other host plants.

M. Kostal (April 9): On April.5 newly hatched larvae were
noticed on apple trees at Morganville. Judging from the numbers of
egg masses, the insect will again be present in large numbers. .

Pennsylvania. R. M. Baker (April 21): Tents of the eastern tent caterpillar
are about a week old. The larvae are feeding on unfolding apple leaves
at Harrisburg, resulting in medium damage. Eggs began hatching at
Berwick on April 9. They are very abundant.

H. E. Hodgkiss (April 23): The eastern tent caterpillar was
forming 'webs in Adams County on April 1. In LIifflin County on April 13
eggs started hatching and 4 days later hatching was general in the
county, which is close to the center of the -State. The infestation
appears to be general, as it was in 1935.

A. B. Champlbin (April 19): Observed in Dauphin County on
seedling apple, leaf buds first unfolding. The caterpillars are just
hatching, and their nests are very small. Some larvae are clustered
on opening leaf buds.

South Carolina. F. Sherman (April 20): Tent caterpillar is common-on wild
cherry. Larvae are now an inch long.

Georgia. 0. I. Snapp (April 17): Recently hatched larvae were observed
on wild cherry trees on March 31 at Fort Valley. The infestation is
only moderate being considerably lighter than last year. Practically
full-grown larvae were observed on April 17.

T. L. Bissell (April 8):. One colony of small tent caterpillar
larvae, apparently r. americana, observed on wild cherry at Experiment
today. (April 23): A few full-grown caterpillars have been taken on
wild plum bushes since April l1.

Mississippi. C. Lyle and assistants (April 24): Specimens of M. americana
were collected at Jackson on March 31. Slight infestations on plum

shade trees, including cherry, apple, cottonwood, elm, hackberry,
boxelder, silver maple, etc., continued to be received during the
period March 21 to April 20. These new-complaints came from the
southeastern one-third of the State.

Oklahoma. F. A. Fenton (April 20): The flat-headed apple tree borer is
still in the larval stage.

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

from orchards in the Roanoke section, and were occurring: in peach
orchards in considerable numbers by April 21.

South Carolina. F. Sherman (April 20): D. Dunavan reports finding crescent
cuts numerous on cultivated plum.

Georgia. 0. I. Snapp (April 1): The peak of appearance of the curculio
from hibernation at Fort Valley occurred on.March 29, and by March 30
the beetles had reached the center of the or'lchrds and were disseminated
throughout the orchards. Shucks were being shed from a few peaches
on March 31. Therefore, the dissemination of the curculio was unusually
late this year in comparison with the development of the fruit. The
appearance of adult curculios from hibernation has not been as heavy
as anticipated. (April 9): The first '-gs of the season were found
today. The most advanced ec- was about 4 drtys old. Very few eggs have
been deposited to date, and noneo have hatched. (April 15): Although
the peak of appearance of adults from hibernation in the Fort Valley
area occurred on March 29, unusually late, very few eggs were deposited


until the week beginning April 13. Rain was recorded on G of the
first 10 days of April for a total of 7.93 inches for that period.
These rains with high winds and cool weather prevented oviposition
of most of the adults until the time indicated above. (April 27):
Larvae began leaving peach drops today, which is 13 days later
than the first emergence last year.

T. L. Bissell (April l1): The curculio continues to be scarce
on peach trees at Experiment. On April 16, l14 weevils were jarred
from a small clump of wild plum and only 4 weevils from 21 peach
trees. (April 23): Curculios continue to be found in small numbers
on peach trees but on April 16 and 22 they were numerous on wild plum.

C. H. Alden (April 21): Curculios commenced emerging on March 23
in the Cornelia section and have been emerging in moderate numbers
since that time. The highest catch in any one morning has been 25
curculios jarred from 10 trees. Commercial growers in the middle
Georgia sections (Thomaston and Monticello) have reported catching over
2, one morning's jarring operations.

G. F. Moznette and S. 0, Hill (April 22).: Half-grown larvae of
the plum curculio at Albany were found in green peaches from a half
inch to an inch in size.

on April 16, andat Hollins and Blacksburg on April 20?

Georgia and Alabama. 0. I. Snapp (April 16): The first twig injury of the
season was observed at Fort Valley today. The oldest larvae in these
twigs were about 3 days old. Eggs began to hatch April 13, which is
about the usual time. Larvae at least one-half grown were reported on
April 12 at Prattville, Ala., which is in about the same latitude as
Fort Valley. The dates of first tvig injury at Fort Valley other years
are as follows: April 10, 1925; April 20, 1926; April 1, 1927; April
25, 1929; April 4, 1929; April 29, 1930; April 22, 1931; May 17, 1932;

ITevw York. N. Y. State Col1. Agr. News Letter (April): The black cherry
aphid began hatching in the Hudson River Valley the last of March.
In the Lake district in Orleans and Monroe Counties aphids were
first observed on the buds the third week'of April.

Montana. A. L. Strand (April 22): The black cherry aphid is present in
very reduced numbers this spring in the Flathead sv'eet cherry district,
Evidently extremely low temperatures in' October of last year had
considerable effect in causing this reduction.
CHERRY CASE BEARER' (Coleophora pruniella Clem.)

Wisconsin. C. L. Fluke (April 20): The severely cold weather of the past
winter apparently did not injure many of the wintering cases. Twigs
brought into the laboratory fror Door County showed almost as many live
cases as in former yoara.


RUSTY PLUM APHID (Hysteroneura setariae Thos.)

:.i!sissippi. C. Lyle (April 24): Specimens of the rusty plum aphid. with
the report that they vwere seriously damaging plum trees were received
from Belzoni on April 17.

serious damage to red raspberry canes at Lewiston and growers are
preparing to s~r?*'


GRAPE LEAF FOLDER (Desmia funeralis Hbn.)

California. H. C. Donohoe and G. H. Kaloostian (April 13): The grape
leaf folder has been reported as doing serious damas,n-- to several
varieties of grapes in the Kings River bottocms near Sanger for the
past 4 years. Examinations of soil in a planting on April 11 indicated
a high population of overwintering pupae. Adult emergence is just

GRAPE ROOT BO?2R (Paranthene polistiformis Harr.)

Kentucky. "7. A. Price (April 25): The grapevine root bo#U has damaged
many vines in a vineyard at Lexington. On removing the vines on April

lo'I.H. H. E. Jaques (April 24): Eggs of the imported currant worm are showing
up on gooseberries in the southeastern part of the State.


PECA1I HTUT WORM. (Acrobasis caryae Grote)

Florida. G. F. iioznette and S. 0. Hill (April 21): The larva of this insect


formerly known as the pecan nut casebearer, was found to be working
in the shoots of pecan on April 21.,' Indications are that it will be
about as abundant in the Mvlonticello pecan section -as last season, whon
from 10 to 30 percent of the nuts were destroyed during May and June.
From present indications, the.pecan crop will be exceedingly light in
the Monticello section this year, and the damage which this insect
will cause will no doubt appear considerable to the growers.

Texan. C. B. Nickels (April 8): An examination of several hundred pecan
!trees near Crystal City and San Antonio on March 31, April 1 and 2,
indicated an extremely severe infestation. of the pecan nut case
bearer. .

PECAN LEAF CASE BEAER (Acrobasis .juglandis LeB.)

Georgia and Florida. G. F. Moznette and S. 0. Hill (April 13): The larvae
of the pecan leaf case bearer were found to be infesting the buds and
new growth in large numbers at Albany, Ga., and Monticcllo, Fla.,
and causing considerable damage,.

HICKORY SHUCK WORl (Laspeyresia caryana Fitch)

Georgia. G. F. Moznette and S.;0-. Hill (April): The moths of the hickory
shuck worm have been.emerging in considerable numbers from the over-
wintering stage within' the shucks on.the ground at Albany, but the
emergence is subsiding somewhat since April 15.

APHIDS (Aphiidae)

Georgia. T. L. Bissell (April 26); At Griffin adult stem mothers of black
pecan aphid, Melanocallis' caryaefoliae Davis, are common, few young. I
see. no leaf injury. Found one adult stem mother of the black margined
aphid, Monellia costalis Fitch. As is usual at this time of year,
adult stem mothers of black spotted aphid, ionellia nigropunctata
Granovsky, and their young are abundant.

Texas. C. B. Nickels (April 25): The giant hickory aphid' was unusually
abundant on pecan and. walnut in Texas during April. Reports were
received that this insect was abundant near the following localities:
Austin, Brady, Brownwood, Burnet, Gatesville, Georgetown, Lampasas,
Lometa, San Antonio, and San Saba. On a small percentage of the trees
all of the branches were nearly completely encircled by the giant
hickory aphid; however, on.a majority of the trees the insect was found
in groups which extended approximately 6-12 inches lengthwise of the
twigs. To obtain information about this, insect front one to six people
called every day during the period April 5 to 25. At present hickory
aphids are more abundant than at any other time during this month.


A SPITTLE BUG (Clastoptera obtusa Say)

Florida. G. F. Moznette and S. 0. Hill (April 21): This spittle bug is
appearing in considerable numbers on the new growth of the pecan in
the Monticello section.


FRUIT FLIES (Anastrepha spp.)

Texas. P. A. Hoidale (April 2): Trapt continue to catch adults both in
Texas groves and in the Mexican brush. During the last 2 weeks 5 adult
A. ludens Loew were taken in Brooks County, and 21 in the lower Rio
Grande Valley, while 10 were taken in the brush south of Reynosa and
Matamoros, Mexico. In all these locations 52 A. sp. "Y"11, 53 A. pallens
Coq., and 16 Toxotrypana curvicauda Gerst. were also trapped. (April 16):
During the past two weeks trapping< operations have been carried on as
usual and during this period 15 A. ludens were taken in the lower Rio
Grande Valley and 7 in northern Hidalgo and Starr Counties. Six of these
flies were taken in the brush.

GREEN CITRUS APHID (Aphis spiraecola Patch)

Florida. J. R. Watson (April 25): The green citrus aphid is quite scarce
for this time of year as the spring flush of growth of citrus has
hardened up and there is very little food for it.

H. T. Fernald (April 22): Citrus aphids scarce at Orlando.

CITRUS WHITEFLY (Dialeurodes citri Riley & How.)

Florida. H. T. Fernald (April 22): Citrus whitefly rather less in evidence
than usual at Orlando, although moderately abundant. Adult maximum
abundance occurred about March 30.

Mississippi. C. Lyle (April 24): The citrus whitefly is reported rather
abundant on its usual hosts by inspectors in the southern half of
the State during the past 2 weeks.

FLOWER THRIPS (Frankliniella tritici Fitch)

Arizona. C. D. Lebert (April 23): The flower thrips has been observed to
be quite abundant on citrus during the past month at Phoenix, and con-
siderable injury has occurred on roses. No citrus injury noticeable
as yet.

SIX-SPOTTED MITE (Tetranychus sexmaculatus Riley)

Florida. J. R. Watson (April 23): The weather, having turned dry during the
last 2 weeks, has given marked impetus to the six-spotted mite, and is
responsible for the heaviest infestation we have seen in several years.
This mite is particularly injurious to grapefruit.


H. Spencer (April 28): The six-spotted mite is quite prevalent in
the orange and grapefruit trees near Orlando. 'iany of the leaves show
the characteristic yellow, distorted spots, and in some few instances
the trees have been defoliated.

CITRUS RED IMITE (Paratetranychus citri McG.)

Florida. J. R. Watson (April 23): Some purple mites were found on citrus,
mixed with the six-spotted mites.

California. H. J. Ryan (April 22): Infestations were on the increase in
Los Angeles County in March, and considerable damage is being caused
in citrus groves.

CITRUS RUST MkITE (Phyllocoptes oleivorus Ashm.)

Florida. J. R. Watson (April 23): The weather having turned dry during
the last 2 weeks, has given marked impetus to rust mites on citrus.


VEGETABLE WEEVIL (Listroderes obliquus Klug)

Georgia. T. L. Bissell (April 1S): There is an error in the April 1
Bulletin (p. 4O) in my note concerning this insect. The pupae found
on March 28 at Clarkston were all alive and not "mostly dead." I
meant to say the turnips were dead from cold. Pupae collected and
caged that day have all transformal to adults during the period April
1-15. Material from other sources is now in the pupal state. No
further epquting has been done.

Alabima. J. M. Robinson (April 21): Adults emerged in large numbers the
last week in March and first 10 days in April. They came out in gardens
and fields where turnips and winter greens were growing last winter,
causing considerable damage to tomato plants set near the gardens.

Mississippi. C. Lyle (April 24): The vegetable weevil is apparently more
abundant than last year. Heavy injury to gardens and truck crops in
the Crystal Springs-Hazlehurst trucking section has been. reported.

Louisiana. B. A. Osterberger (April 23): Vegetable weevils have been
active in many parts of the State, attacking principally vegetable and
truck crops.

California. H. J. Ryvan (April 22): The vegetable weevil was found this year,
as in 1935, generally distributed south and southeast of Los Angeles.
Heavy larval damage occurred along the edge of a celery field at Lomita.


R. E. Campbell (April 15): To the list of localities where
the vegetable weevil is found in California, which we forwarded to
you in June 1935, the following may be added: Chula Vista, Bonita,
Spring Valley, East San Diego, and National City, in San Diego County;
and East Santa Barbara, Montecito, and West Santa Barbara, in.Santa
Barbara County. (April 23): Citrus seedlings in a nursery at East
Whittier, Los Angeles County, are being defoliated by the adults.
Larvae bred on mustard cover crop, which has been plowed under.
The adults are emerging in great numbers and, finding little food,
are attacking the citrus seedlings. They are abundant in nearby citrus
orchards and feeding on oranges which drop* to the ground, 17 beetles
being collected on one orange.

SPOTTED CUCUMtfR BE2TLE (Diabrotica duodecimpunctata Fab.)

South Carolina. F. Sherman (April 20): Spotted melon beetles are out in
numbers on various plants. One report indicated abundance on young
cucumber plants.

Georgia. T. L. Bissell (April 23): Cucumber beetles were very abundant
on peach trees at Experiment the latter part of Mardh, when they were
in blossom, averaging about eight to the tree. Diggings have been made
for larvae in legumes and grass for a month but none were found until
April 20, when a second-instar larva was taken from roots of vetch,
and the next day a first-instar larva was taken on corn. Beetles have
laid eggs in the insectary since February 29.

STRIPED CUCUMBER BEETLE (Diabrotica vittata Fab.)

South Carolina. F. Sherman (April 20): D. Dunavan reports having seen
active specimens of the striped melon beetle.

Georfia. T. L. Bissell (April 20): One striped cucumber beetle found on

SEED CORNT MAGGOT (Hylemyia cilicrura Rond.)

Virginia. H. G. walker (April 21): Adults of the seed corn maggot are
rather abundant in the field near Norfolk, but very little injury has
been reported.

South Carolina. W. J. Reid, Jr. (April l14): The seed corn maggot caused
serious injury to the germinating seed of experimental plantings of
cucumbers near Charleston. The damage necessitated replanting
the crops. The germinating seed of an experimental planting of sweet
corn at the Truck Experiment Station, Charleston, was found to be
infested, many of the seeds having been destroyed. The unusual degree
of injury caused by the insect is attributed to the delayed germination
of the seed resulting from cold, wet soil.


TARNISHED PLANT 3BUG (Lygus pratensis L.)

Colorado. S. C. McCampbell (April 27): The tarnished plant bug is causing
severe injury to spinach, cabbage, and cauliflower around Pueblo and
Canon City. In one instance the bugs were abundant on rhubarb.


COLORADO POTATO BE-ETLE. (Leptinotarsa decemlineata Say)

Virginia. H. G. Walker (April 21): The Colorado potato beetle is rather
abundant in many fields of potatoes at ilorfolk where they have
deposited quite a few eggs. No young larvae have been found to date.

Virinia. H. G. Walker (April 21): The tobacco flea beetle (E. ar Fab.)
and the potato flea beetle (E. cucumeris Harr.) are present in the Norfolk
district, but have not done much feeding on potatoes.


CORN EAR WORM (Heliothis obsoleta Fab.)

Utah. H. L. Blood (1936): The tomato fruit -wor has been exceedingly
abundant and troublesome for the past 2 years. This insect has been
held responsible for a 10 percent reduction in tozato production,
resulting in a loss of approximately $404,000. This figure is not
representative of the total loss suffered by the industry from the
abundance of the worm. An increase in production costs, with a proportion-
ate reduction in the net income of the processors, would not be reflected
in the reduction in total value of the crop to the industry on a produc-
tion basis and, consequently, such a loss would necessarily augment the
production losses from the ravages of the insect. Under the Federal
Food and Drugs Act, filthy or decayed products are prohibited, and
tomato products containing ',"orms or worm fragments come within this
restriction. In order to. comply with this requirement the processors
have had to adopt a more careful sorting and training than had previously
been employed. Meeting this requirement has added a cost estimated at
$85,000 and increased the loss to the State resulting from the fruit
worm to approximately .1495,000, or about 20 percent of the total loss
to the industry in Utah from diseases and other causes.

California. J. C. Elmore (April 2-7): A survey of tomato fields at El
Centro, Brawley, Westmoreland, and Iiland failed to locate any corn
ear worms on tomato. Tear Santa Ana on April 9, seven moths were
collected at lights between 9 and 9 p'm. They laid eggs under outdoor
conditions at Alhambra.

BEET A_ ivOR.:L(Lephygma exigua Hbn.)

California. J. C. Elmore (April 2): Beet armyworm is common on tomato
vines near Niland, attacking foliage and fruit, but losses are not
unusually heavy.

TOMATO PI1XOR.! (Gnorimoschema lycopersicella Busck)

Virginia. H. G. ',Wal:er (April 21): The tomato pinworm was rather abundant
late last summer in a greenhouse near Norfolk where late fall and early
spring crops of tomatoes were being grown. As a result, a fall crop of
tomatoes was not planted last year, and so far no evidence of pinworms
has appeared in the spring crop, which was planted in January.

California. J. C. Elmore (April 7): Tomato fields which have survived the
winter in the early tomato growing areas near Santa Ana, Orange County,
are very heavily infested. There are hundreds of larvae per plant. New
fields near the old ones are already heavily infested.


MEXICAN BEAN BZLTLL (Epilachna varivestis Nuls.)

Ohio. N. F. Howard (April 9): Survival of the Mexican bean beetle at Columbus
remains between 2 and 3 percent, as reported a month ago.

and McAdams.

Texas. F. L. Thomas (April 22): J. N. Roney reports that in Wharton
County on April 16 the bean leaf beetle- had almost completely
destroyed about 10 rows of string beans.


PEA APHID (Illinoia pisi Kalt.)

Virginia. H. G. Walker (April 21): The pea aphid is from scarce to
relatively abundant on alfalfa, but very scarce on peas in the
vicinity of Norfolk.

Mississippi. C. Lyle (April 24): The pea aphid is reported as less
abundant than usual on Austrian winter peas at Poplarville.
Examination of pea fields in the Crystal Springs-Hazlehurst trucking
section on April 4 failed to show any infestation.

California. R. E. Campbell (April 15): Most of the pea fields of Santa
Clara County are moderately infested. Cold weather during the first
part of April checked multiplication, but recent warm weather has
caused a build-up which will undoubtedly be sufficient to cause
injury before harvest time.



Virginia. i1. G. Walker (April 21): Butterflies are moderately abundant
at Norfolk. Eggs and small worms are present but very scarce.

South Carolina. F. Sherman (April 20): White cabbage butterflies have
been in flight several weeks.

numerous and eg{s are easily found. So far no Trichogramma parasites
have been found in the eggs collected.

California. J. C. Elmore (April 2): A looper, either A. brassicae or A.
californica Speyer, was common on tomato vines near ITiland, attacking
fruit and foliage.

CABBAGE APHID (Brevicoryne brassicaee L.)

Virginia. H. G. Walker (April 21): The cabbage aphid is very scarce at
Norfolk except in a few fields where the aphids were brought in with
the plants from the South.

South Carolina. J. A. Berly (April 20): The cabbage aphid is prevalent
on cabbage in gardens at Clemson.

Georgia. T. L. Bissell (April 18): Aphids are scarce on cabbage at

Mississippi. C. Lyle and assistants (April 24): The cabbage aphid is
apparently more abundant than usual in most parts of :iississippi and
has caused very heavy damage in the Crystal Springs-Hazlehurst
trucking section. It is reported that hundreds of acres were plowed
up on account of dvmaje. Only medium injury is reported on home-
grown plants, the heaviest loss occurring on imported plants. A
heavy infestation was noted on collards at Poplarville late in

HARLEQUIN BUG (Murgantia histrionica Hahn)

Georgia. T. L. Bissell (April 13): Comparatively few harlequin bugs have
been seen this year on collard at Experiment.

Alabama. J. M. Robinson (April 21): The harlequin cabbage bug continues
to increase in abundance, coming from its hibernation places. These

7lashington. .. C. Lane and E. W. Jones (April 16): This beetle was found
in destructive numbers in several asparagus fields in the Walla Walla
Valley. Last year only a few scattered infestations were reported.
It is evidently gaining a foothold in the rapidly expanding asparagus
districts of the Walla Walla Valley.

California. R. E. Campbell (April 15): Several asparagus fields in Los
Angeles County are badly infested with asparagus beetles. Many new
stalks are ruined by deposits of eggs.


SQUASH BUG (Anasa tristis DeG.)

Idaho. C. Wakeland (April 21): The squash bug has spread throughout
southwestern Idaho and has extended its range eastward as far as King
Hill. Another infestation occurs in Franklin County, in the south-
eastern part of the State,


GREEN PEACH APHID (Myzus persicae Sulz.)

Virginia. H. G. Walker (April 21): The spinach aphid (L. persicae) has
been very scarce or entirely absent from iNorfolk since the fungous
disease killed off the heavy infestation last fall.


BEET LEAFHOPPER (Eutettix tenellus Baker)

T^-s. D. W. De Long and R. K. Fletcher (April 22): A brief survey to
determine the presence, abundance, and distribution of the beet
leafhopper in the Winter Garden section of Texas was made from April
l4 to 1S. Beet leafhopper was found in Zavala, Dimmit, maverick,
and Webb Counties. Spinach was found to be badly diseased. Curly
top reported.

California. S. Lockwood (April 30): Inspection of a sugar beet field
in Fresno County on April 27 showed the sugar beet leafhopper to be
especially numerous in the field. Counts showed approximately five
leafhoppers per plant.

APHIDS (Aphiidae)

New Mexico. R. E. McDonald (April 20): J. IT. Crisler writes that aphids
are doing serious damage to sugar beets in the lower Ilesilla Valley.
Some of the beets may have to be plowed up as a result of injury by
this insect.



TOBACCO FLEA BEETLE (Epitrix parvula Fab.)

ITorth Carolina. C. H. Brannon .(April 27): Iany tobacco beds have been
severely damaged this year. Practically all beds show evidence of

had not been any boll weevil activity in the hibernation cages at
Eufaula, where we have 25,550 weevils in hibernation. So far very
little cotton has been planted.

PINK BOLLWORM (Pectinophora gossypiella Saund.)

Puerto Rico. L. C. Fife (April l14): At Aguadilla about 50 plants of soca
cotton bearing many mature green bolls were found --r-'-ing in a field
of plant cotton that was just beginning to bloom. Of 93 mature green
bolls examined, 50, or 55.6 percent, were found to be infested with
pink bollworm larvae in all states of development. T,:o cotton fields
planted December 15, 1935, at Isabela were heavily infested. Of 87
mature green bolls examined from one of these fields, 47, or 54 percent,
were infested. In the othsr field 30 bolls were e:-amined and 15, or 50
percent, were infested. Blooms were also heavily infested in this field.
Cotton was planted in these and adjacent fields last year. The old
cotton plants of the 1935 crop were destroyed only a week or so before
the planting of the 1936 crop. In some adjacent fields the old plants
were cut down and piled, but had not been burned. An examination of
the seed cotton in these fields showed that it was heavily infested
with the pink bollworm (long-cycle larvae). These facts clearly
explain why the infestation is so high in these fields. Another
field examined at Isabela showed an infestation of 10 percent. The
heaviest infestation on the northern coast during 1935 occurred at
Camuy; however, no cotton plantings in this locality are bearing
mature green bolls at present. Two hundred mature green bolls were
examined from two fields at Quebradillas on April 6. The infestations
in these fields were 2 and 4 percent, respectively. Only one small
experimental plot of Meade cotton was grown at Arecibo last year.
During the present season, possibly 700 acres are grown in this
locality. Two hundred mature green bolls from two fields planted
December 15, 1935, were examined but neither field was found infested.
At Hatillo, mature green bolls from two different fields were examined.
Only one of these fields was found to be infested.

COTTON APHID (Aphis gossypii Glov.)

Arizona. T. P. Cassidy and T. C. Barber (April 18): In the vicinity of
Buckeye in the Salt River Valley cotton lice are very prevalent on
the foliage of sprouting stubble cotton.

Puerto Rico. L. C. Fife (April 14): The cotton aphid was found in most of
the plantings on the northern coast, but no serious damage was observed.

FIELD CRICKET (Gryllus assimilis Fab.)

Mexico. C. S. Rude (April 1h): Field crickets continued to be a serious
pest in the cotton fields of the Laguna district of Mexico. In some
places the cotton is recovering from the cricket damage but in others
replanting will be necessary. This is a serious situation, as there
is not enough seed in the Laguna for replanting and, with exchange and
financial conditions as they are, it will be very difficult to import
the cotton seed.

COTTO:0 BLISTER MITE (ErioPhye_ goseypii Bke.)

Puerto Rico. L. C. Fife (April 14): Young cotton plants 12 inches high
were found to be heavily infested with the West Indian blister mite
(E. Zossypii) in one field at Isabela on April 6. Many of the fruiting
branches on these plants have been destroyed. This infestation
originated from infested new growth .on old cotton plants of the 1935
crop that had not been destroyed in an adjacent field.


CAM1RWORMS (Geometridae)

Connecticut. B. H. Walden (April 24): Eggs of Alsophila pometaria Harr.
are abundant in IT7'v Haven County. No indications of hatching.

Hew York. IT. Y.StateColl. Agr. News Letter (April 13): Several cankerworm
eVj masses have been observed in Greene County.

New Jersey. H. W. Allen (April 20): A considerable number of egg clusters,
apparently of fall cankerworms, have been noted in the vicinity of
Moorestmwn. As this insect was not present in destructive numbers in
this vicinity last year, the presence of considerable numbers of egg
clusters may indicate the probability of an appreciable infestation
during the coming season.

Michigan. R. Hutson (April 20): 12g1 of canker'erms aro abundant about
Lansing, Grand Rapids, and Owosso.

FOREST TENT CATERPILLAR (Malacosoma disstria Hbn.)

Mississippi. C. Lyle (April 24): A heavy infestation of the forest tent
caterpillar is occurring again this year in the extreme southern part
of the State. Sweetgum and oak trees, especially, are being defoliated
in Pearl River, Hancock, Harrison, and MIriQn Counties. Many people are
alarmed at the enormous numbers of the insect.

BAGWORM (Thyridopteryx ephemeraeformis Haw.)

New Jersey. H. W. Allen (April 20): There is somewhat heavier infestation
of bagworm than usual in evidence in southern New Jersey. Many bags
are present in thickets of locust, on young sycamores in street plantings,
and occasionally on ornamental evergreens. A considerable portion of the
female bags contain no healthy eggs, so the infestation of caterpillars
may not be heavier than usual.

Louisiana. B. A. Osterberger (April 20): A few very small bagworms were
received from Covington.


ELM LEAF BEETLE (Galerucella xanthomelaena Schr.)

Pennsylvania. E. P. Felt (April 24): Adults were found wintering in large
numbers in a building in the Philadelphia district.

Idaho. C. Wakeland (April 21): The elm leaf beetle has spread throughout
southwestern Idaho and reached eastward as far as Gooding. Northward
in the State it is known to occur in Moscow.

California. C. S. Morley (April 5): Elm leaf beetles have been found
feeding on elm leaves in several places within the city limits of
Bakersfield during the last 2 weeks. Elm trees were not sprayed last
year, which resulted in many overwintering beetles that threaten the
foliage of elm trees this year.

EUROPEAIT ELM SCALE (Gossyparia spuria :.Iod.)

Illinois. W. P. Flint (April 20): The cold weather of the winter
apparently had only very little effect on the European elm scale. Recent
examinations of this insect have failed to show more than the normal
winter mortality.

Idaho. C. Wakeland (April 21): European elm scale was heavily killed last
winter by temperatures in northern Idaho.

EUROPEAN FRUIT LECANIUM (Lecanium corni Bouche)

Oklahoma. F. A. Fenton (April 20): The European fruit Lecanium has proved to
be far more destructive this year than last. Most of the damage appears
to be on elm trees, particularly the American elm. At present the
females have nearly completed egg deposition.


A NEEDLE MINER (Recurvaria apicitripunctella- Clem.)

Connecticut. G. H. Plumb (April 13): The insect seems to be fairly
abundant on hemlock' at Hamden. Larvae of both brown and green colors
were found, and pupae were found 3 days later. They eat only the
under surface of some- needles and mine .inothers.


LARCH CASE BEARER (Coleophora laricella Hbn.)

Vermont. H. L. Bailey (April 25): Cases of the larch case bearer found
moderately abundant on trees in Glover, Orleans County, and very
abundant in Cabot, WashingtonCounty, on April 23.

Connecticut. E. P. Felt (April 24): Larch case bearers have commenced
feeding on the young needles and are locally abundant.


A BORER (Agrilus difficilis Gory)

Colorado. J. A. Beal (April 7): The honeylocust (Gleditsia triacanthos),
a tree widely used in early windbreak plantings and in the new plant-
ings because of its supposed immunity to insect injury, has,, during
the past summer, been heavily attacked and killed in many plantings.


TERRAPIN SCALE (Lecanium nigrofasciatum Perg.)

Connecticut and Pennsylvania. E. P. Felt (April 24): The black banded
scale was quite abundant on maple in the Philadelphia district and
also at Bridgeport, Conn.


A BORER (Aegeria mellinipennis Bdv.)

California. H. J. Ryan (April 22): This borer was found to be causing
considerable damage to two large California live oaks on a residential
property in San Marino.

AN OAK SCALE (Lecanium quercifex Fitch)

Mississippi. C. Lyle (April 24): Heavy infestations of the oak lecanium
were reported during the month from UTtica, Meehan, Poplarv.ille, and

A TUSSOCK MOTH (Halisidota ingens Hy. Edw.)

Arizona. M. W. Blackman (March.26): These caterpillars are apparently
doing serious damage to Ponderosa pine in the Apache National Forest.
The conditions as described seem rather alarming. (Determined by
C. Heinrich.)

WHITE-PINE WEEVIL (Pissod-. strobi Peck)

Pennsylvania. E. P. Felt (April 24): Some injury to Austrian pine occurred
in the Philadelphia area, though in New England this insect shows a
marked preference for white pine.

A EIDGE (DI plosis ijnopis 0. S.)

Connecticut. G. H. Plumb (April 20): A light-to-moderate infestation has
been observed on Scotch pine in re'., Hartford. Where the larvae were
working near the tips of the twigs, the bud clusters appeared to be
affected. In most cases the lesions were formed about the base of
a needle, although this was not always true.

PINE NEEDLE SCALE (Chionaspis pinifoliae Fitch)

Connecticut. W. E. Britton (April 2h): Specimens received fromnBristol
and Wethersfield, where they were taken on mugho pine.

Nebraska. M. H. Swenk (April 8): On April S some spruce trees in Sioux
County were reported to be infested with the pine leaf scale.


BEAMED WILLOW GALL (Phytophaga rigida O.S.)

New Jersey. E. P. Felt (April 24): Reported as somewhat abundant on
willows at Palisades Park.



CUBAY-LAUREL THRIPS (Gynaikothrips uzeli Zimm.)

Florida. J. R. Watson (April 23): Complaints were received of the
depredations of the Cuban-laurel thrips from Sarasota and Babson Park.
This is a very serious pest of Ficus nitida and F. religiosa, making
the growing of these ornamentals almost impossible. Because the
thrips curls up the young leaves very tightly it is impossible to get
at it with an effective spray.

OYSTER -SHELL SCALE (Lepidosaphes ulmi L.)

District of Columbia. W. Middleton (April 2): Oyster-shell'scale collected
cn elm trees in Washington. (Identified by H. Morrison.)

Indiana. J. J. Davis (April 26): Apparently the winter had little harmful
effect on the oyster-shell scale.

Idaho. C. Wakeland (April 21): Oyster-shell scale was heavily killed by
temperature of the last winter in northern Idaho.

COTTONY-CUSHION SCALE'(Icerya purchase Mask.)

Mississippi. C. Lyle (April 24):- On April 17 the county agent of Hattiesburg
sent specimens of cottony cushion scale which, he stated, was very
abundant on hedges in that city. This insect also occurs 'on some
properties in Laurel. Ladybeetles are being distributed as rapidly as

AZALEA SCALE (Eriococcus azaleae Comst.)

Mississippi. C. Lyle (April 24): Infestations of the azalea scale have been
found during the past month at Pascagoula and Meridian. In both cases
the infestations were traced to infested plants from a nursery in Mobile.
Every effort is being made to clean up the infestations and prevent the

DOGWOOD CLUB GALL (Lasioptera clavula Beutm.)
Connecticut. E. P. Felt (April 24): The dogwood club gall was found to be
somewhat abundant on newly transplanted flowering dogwood.


JUNIPER WEBWORM (Dichomeris marginellus Fab.)

Connecticut. E. P. Felt (April 24): The juniper webworm was somewhat abundant
on Irish juniper at New Canaan.

WHITE PEACH SCALE (Aulacaspis pentagon Targ.)

Connecticut and New York. E. P. Felt (April 24): White peach scale was found
in some numbers on lilac at Darien, Conn., and Huntingdon, Long Island, N.Y


APHIDS (Aphiidae)

Texas. R. E. McDonald (April 20): Aphids are reported as doing considerable
damage to roses in the El Paso and Mesilla Valleys.





HUMAN FLEA (Pulex irritans L.)

Indiana and Missouri. E. C. Cushing (April 25): Reports received from
several localities in Indiana and Missouri indicate that the human
flea is beginning to appear and has already become abundant enough
to cause considerable annoyance in dwellings.


Delaware. L. A. Stearns (April 15): Larvae and pupae of this species are
abundant in water holes on salt marsh near Odessa.

CLUSTER FLY (Pollenia rudis Fab.)

Ohio. N. F. Howard (April 21): Very abundant in a house at Worthington
during February and March.

Indiana. J. J. Davis (April 2r): The cluster, or attic, fly was frequently
reported from the northern half of the State during March and the
early part of April, as being very annoying in homes.

Michigan. Ray Hutson (April 20): The cluster fly has been reported from
Oxford, Delta, Dimondale, and Charlotte, as causing annoyance in

Wisconsin. C. L. Fluke (April 20): There is practically no insect activity
except appearances of large numbers of cluster flies.

TROPICAL RAT MITIE (Liponyssus bacoti Hirst)

Texas. R. E. McDonald (April 11): Mites taken from a bedroom in San
Antonio on April 6 have been identified-as the tropicalrat mite.


TRUE SCREW WORM (Cochliomyia americana C. & P.)

Texas. E. C. Cushing (April 25): A survey of Jackson, Matagorda, and
Brazoria Counties on April 2, by W. J. Spicer, shows that screw worms
have not yet become active in this section of Texas this season. Most
of the infestations in these three counties this season have been
due to Phormia spp.

CATTLE G:RUBS (Hypoderma spp.)

Illinois. E. C. Cushing (April 25): A scarcity of ox warble grubs was
reported inthe vicinity of Galesburg.

Minnesota and Iowa. E. C. Cushing (Aprii 25): Surveys made by R. W. Wells
and H. 0. Schroeder on April 9, 10, and 11 in southeastern Minnesota
and northeastern Iowa show infestations of animals to be very light
in these areas. Several hundred head of cattle were examined and
grubs were very rare in mature animals. The yearlings and 2-year-olds
carried a few, the largest number found in a single animal being 10.

Kansas. H. R. Bryson (April 6): Cattle observed running from heel flies
at Anthony and Wellington. Reported running in March by one stockman
near Manhattan. In Bourbon County heel flies were seen chasing cattle
about the middle of March.

A HORSEFLY (Tabanus sp.)

Texas. E. C. Cushing (April 25): W. J. Spicer, screw worm scout,
reports on April 2 a rather severe outbreak of a small tabanid in the
wooded section of Brazoria County. He states that cattle have been
considerably annoyed by this pest since about March 15.

SHORT-NOSED CATTLE LOUSE (HaematQpinus eurysternus Nitz.).

Kansas. H. R. Bryson (April 7): The broad-nosed ox louse very abundant in
many herds in Harper County, Many farmers are requesting remedies.

LONE STAR TICK (Amblyomma americanum L.)

Mississippi. H. Gladney (April 24): Specimens of this tick were collected
in Jackson County. The ticks were so numerous in the yard that a
person would soon be covered with them.


DEER BOTFLY (COphenomyia pratti Hunter)

Utah. G. F. Knowlton and C. F. Smith (April 7): An examination of a series
of dead and very much weakened deer 'in the vicinity of Logan showed
mostof those examined to be heavily infested with bot maggots in the
gular pouches. Many deer are dying from starvation, probably aided by
excessive infestation of parasites.


AMERICAN DOG TICK (Dermacentor variabilis Say)

Maryland and Virginia. E. C. Cushing (April 25): Several infestations of
dogs by the American dog tick have been reported from points in
Maryland and Virginia near Washington, D. C.



IER IITES (Reticulitermes spp.)

Connecticut. N. Turner and M. P. Zappe (April 24): Fifteen samples of
winged termites (R. flavipes Kol.) were received for identification
and 16 infested buildings inspected during the past month. A random
sample survey of the State made during the winter showed that about
25 percent of all buildings inspected were infested, and about 30
percent of all wooden buildings showed the presence of termites.
The buildings were of varying age and construction.

New York. R. D. Glasgow (April 27): During the past 6 weeks we have
identified termites swarming into the interior of houses at Albany,
Schenectady, and Mount Vernon.

Pennsylvania. R. M. Baker (April 21): Many reports of termite damage are
coming in from scattered localities throughout most of the State.

Delaware. L. A. Stearns (April S): Specimens of injury to house structure
at Hockessin examined; termites present.

Ohio. T. H. Parks (April 24): Swarraming of termites did not. occur until
about the middle of April, about 3 weeks later than usual.
Judging from the reduced number of calls for aid, compared with those
received during the past 4 years, termites have suffered from severe
winter temperatures, along with many other insects.

Indiana. J. J. Davis (April 26): The usual large numbers of inquiries
about termites have been received. S'.'armin forms first made their
appearance in January and migrations are still being reported.

Illinois. W. P. Flint (April 20): Swarms have been appearing at many
points in central Illinois during the last 3 weeks.

Kentucky. W. Price (April 25): Termites, as usual, are the subject of many
inquiries this spring. The first swarms were noticed in Lexington on
March 2.

Nebraska. M. H. Swenk (April 17): On Liarch 26 a report was received of an
infestation of R. tibialis Bks. around a Douglas County house,, and on
April 17 a report of them about the roots of trees near the foundation
of a Gage County house.

Kansas. H. R. Bryson (April 6): The usual numbers of inquiries about
control of termites have been received, also reports of injury from
Wellington, Manhattan, and other localities.

Oklahoma. C. F. Stiles (April 22): onerousus flights of the sexed forms
of termites have been observed in Payne, Ottawa, Haskel, Jefferson,
and Pontotoc Counties.

ANTS (Formicidae)

New York. R. D. Glasgow (April 27)i: During ,the past 6 weeks we have
identified carpenter ants swarming into houses at Millbrook, Loudonville,
Schenectady, and Albany.,

Nebraska. M. H. Swenk (April 20):O Rports. of the presence of the basement
ant (Lasius interjectus Mayr) around 'the' foundation of houses in
Douglas County were received-during the period March 21 to April 20.

Oklahoma. F. A. Fenton (April 20) :.' A number of inquiries have been received
on control of household ants.

Mississippi. C,. Lyle (April 214): Fire' ants (So6lenopsis xvlofni McCook)
have caused trouble in several places during the month. Inspector J.
E. Lee reports several complaints of damage to clothe's by this ant.

Utah. G, F. Knowlton (April 11); Ants are very troublesome in a home at

INDIAN-MEAL MOTH (Plgdia intepun6ctella Hbn.)

California. H. C. Donohoe (April 6): Samples of stored 1935 crop,
unprocessed seedless raisins from .storage at Kingsburg on February
25 averaged less than 175 larvae per ton. Similar samples in March
1935 before adult emergence averaged approximately 750 per ton.

DRIED FRUIT MOTH (vitula serratilineella Rag.)

California. H. C. Donohoe (April 4): Unprocessed*1935 crop seedless
raisins in storage at Kingsburg, were found slightly infested by larvae
of the' dried fruit moth during February. This is the first record of
raisin infestation by this species in the San Joaquin Valley within
the past 5 years. (April 27): Adults of the 'spring brood we're mere
abundant than normally in a packing house in Napa on April 16. They
were more than 20 times as abundant as those of the raisin moth, which
Is usually predominant.

RAISIN MOTH (Ephestia figulilella Greg.)

Arizona. H. C. Donohoe (April 4): Examinnation of miscellaneous larvae
found infesting dates in the Experimental Date Garden at Tempe,
collected by P. Simmons and D. F. Barnes in i-Tovember 1935,-yielded
one raisin moth larva. This is the first record of this insect in
the field in fruit in any area outside the State of California.

California. H. C. Donohoe (April 4): Studies of winter mortality in soil
of raisin moth in the vicinity of a raisin storage at Kingsburg indicate
that, at the start of spring pupation the last of March, mortality in
continuously wet soil approximated 100 percent; in that only occasionally
moistened, over 70 percent; and in dry, protected soil, no more than
30 percent. In the wet soil the increase in mortality was greatest
during February, a period of excess rainfall. Over 150 samples of


unprocessed, stored, 1935-crop raisins collected at Kingsburg on
February 25, yielded an average infestation of approximately 6,400
live raisin moth larvae per ton, these having survived the winter. A
similar survey in March 1935 indicated a survival of 1,100 per ton.

A PYRALID (Ephestioides nigrella Hulst)

California. H. C. Donohoe (April 4): Samples of stored, unprocessed 1935-
crop seedless raisins, collected at Kingsburg on February 25, contained
light infestation by larvae. Although adults are frequently encountered
about raisin storage early in the spring, this is the first definite
natural host record for this species.

A PYRALID (Aphomia gularis Zell.)

California. H. C. Donohoe (April 27): Adults of the spring brood are
emerging in prune storage in San Jose. They are more abundant than
hitherto noted, and larval cocoons indicate an unusually high over-
wintering population in two of four packing plants visited on April lS.

PEA WEEVIL (Bruchus pisorum L.)

Idaho. C. Wakeland (April 21): At Moscow about one-third of the pea weevils
in the most favorable positions overwintered successfully, according to
a report by T. A. Brindley. ;'eevils in cages placed in Weather Bureau
kiosks survived at Buhl, Twin Falls, Jerome, Rupert, Bliss, Pocatello,
and Burley. In l4 other locations where cages were placed mortality in
cages was complete.

TEMEBRIONIDS (Blapstinus spp.)

California. D. F. Barnes and H. C. Donohoe (April 13): During the past
winter the relatively rare beetle, B. sulcatus Lec.,has been taken in
large numbers beneath timbers, in the soil, and in raisin trash about
a stack of stored 1935 raisins at Kingsburg.

D. F. Barnes and C. K. Fisher (April 29): Migration of adults
of both sexes of B. rufipes Csy. by flight as well as by crawling was
observed March 19 in Fresno County. This is the first observation we
have made of the flight of this species. Females containing eggs were
first collected on April 16.

DRIED FRUIT BEETLE (Carpophilus hemipterus L.)

California. D. F. Barnes (April 29): These beetles were taken throughout
the winter in traps baited with fermenting dried peaches and set in a
fig orchard in Fresno County. With the exception of about 1 month
(December 16 to January 20) they were caught in traps in an area of
grain land several miles from known supplies of food.

G. N. Wolcott

Since the middle of December, less than 2 inches of rain has
fallen in Pu.rto Rico--much less than the normal rainfall for this
time of year. Th]e effect on certain insects has been very notice-
able. The tobacco leaf minor (Gnorimoschema o)oerculolla Zell.) is
st{ructively abundant in tobacco-grol-in& districts that ordinarily
cscrpe injury entirely.

The effect of the weather on scale insects is also very
noticeable, especially in citrus groves of su.c', rugged contour that
entomo-enous fungi ordinarily can be depended on for commercial con-
trol. On some pnpa:Ta trees that had booeen sprr;c:d with miscible oils
to control the West Indian peach scale (Aulacaspis 2cntagona Targ.),
what ordinarily would be commercial control was obtained, but even
a very small survival caused complete reoinfcstation 2 or 3 months

The yellow sugnrcane aphid (Sipha flav. Forbes), is generally
supposed to be :niore or less effectively controlled by hc-.v:y rainfall.
This winter and spring, when there has been practically no rainfall,
the drought seems to have been effective in preventing even the be-
ginning of field infestations, as none has been reported. An ox-
tenc'ed search in the Isabella district failed to disclose any.

The lima bean pod borer (Maruca tostulalis G.oyer) was de-
structively abundant in lima and snap beans at Yauco and Isabela
last fall. In a lima bean plot at Isabela, from which samples have
been harvested this late winter and. spring, not a single caterpillar
has been found. During the winter, a light infestation by Fundella
cistipennis Dyar'was noted. A normally heavy infestation by Etiella
zincklenella Treit. developed this spring.

The onion thrips (Thrips tabaci Lind.) has entirely destroyed
many onion plantings.
