THE MORE IMPORTANT RECORDS FOR JULY 1935
The grasshopper and chinch bug situations have not materially changed
since our last report.
The occurrence of two Asiatic weevils, Myllocerue castaneus Roelofs
and Calomycterus setarius Roelofs, in the Middle Atlantic States was probably
the most interesting feature of the month. M. castaneus was first collected
in 1933 at Montclair, N. J., and was again collected this year at the same
place. Although this species is not recorded as a pest in Asia, the genus
contains many species that are crop pests, and one a very serious pest of
cotton in India. C. setarius was first collected in this country at Yonkers,
N. Y., in 1929. In 1932 it was reported as injuring iris and other plants
in Connecticut, and this year it was again found in that State attacking
greenhouse plants, and was found in enormous numbers in Maryland and Pennsyl-
vania feeding on a wide variety of plants.
The Japanese beetle was occurring in increasing numbers in the central
portion of the main infested area, and in the outlying parts of the generally
infested area the populations are decidedly on the increase.
Common red spiders occurred in destructive numbers from Maryland to
Florida and westward to Nebraska and Mississippi, with isolated reports from
the Great Basin and the Pacific Northwest.
Early in the month the corn ear worm was reported quite generally
throughout the Northern States as doing serious damage to tomatoes in many
sections. During the latter part of the month it was reported as injuring
Scouting for the alfalfa weevil has resulted in the finding of this
insect in Sioux and Scotts Bluff Counties, Nebr.; Montezuma County, Colo.;
Kane County, Utah; Clark County, Neve; Coconino County, Ariz., and Mendocino
County, Calif#; and in confirmation of its occurrence in Malheur, Baker, and
Union Counties, Oreg., as well as in various other counties previously
known to be infested.
The apple maggot emerged later than usual in New England and New York
and was appearing early in July in Michigan and Wisconsin.
The plum curculio is apparently less troublesome than was at first an-
ticipated, dry weather preventing the new beetles from depositing many eggs,
particularly in the Fort Valley peach-growing district of Georgia.
The oriental fruit moth appeared to be decidedly on the increase from
the East Central States southwerd to Tennessee and Mississippie
A localized outbreak of the cherry leaf beetle was reported from
western Maryland and West Virginia.
The Colorado potato beetle appeared in unusually destructive numbers
from Ohio and Indiana westward to Minnesota and the Dakotas.
The Mexican bean beetle was reported from central Iowa, far west of
its known distribution outside of the Rocky Mountain region.
The imported cabbage worm is generally prevalent and destructively
abundant from Ohio to Minnesota'and Kansas, and is reported as doing consider-
able damage in Utah.
Curly top destroyed many plantings of tomatoes in southwestern Idaho
and northern Utah.
Cotton aphid infestations were reported from the entire Cotton Belt,
but especially from areas where arsenicals had been used extensively to con-
trol the boll weevil and cotton leaf worm.
The satin moth was found in eight counties in the Villamette Valley
The b-gworm was reported as destructively abundant throughout the
New England, Middle Atlantic, East Central, and Gulf Coast States.
The elm leaf beetle was reported as seriously damaging elms throughout
the New England and Middle Atlantic States, southward to North Carolina, and
westward to Ohio. Severe defoliation of elms was also reported from the
The screw worm continued to cause enormous losses to livestock in
Texas, whereas in the Southeastern States losses have been far less serious
during the month*
Wisconsin. E. L. Chambers (July 23): Although grasshoppers are prevalent
over most of the infested area, the losses have been restricted to
parts of less than a dozen counties where local rains have not been
North Dakota. F. D. Butcher (July 7): Third-instar and fourth-instar
nymphs of the clear-winged grasshopper (Camnula pellucida Scudcl.) were
migrating across the highway from a pasture to a small-grain field, in
a strip about 10 rods wide, at Hurdsfield, Wells County. (July 12):
In a population of about 12 grasshoppers per square yard, Melanoplus
mexicanus Sauss, was the predominant species. In a population com-
posed of forms ranging from thirc-instar nymphs to adults, less than
1 percent had reached the adult stage at Ellendale and Lisbon, where
the concentration was about 5 per square yard.
South Dakota. H. C. Severin (July 22): Infestations are very spotted and
range from very light to heavy. Some damage has been done to gardens,
small grain, and alfalfa. Range grass has suffered slightly.
Iowa. H. E. Jaques (Jul!- 22): Many grasshopper nymphs are now in evidence
in southeastern Iowa.
Nebraska. M. H. Swenk (July 15): Mild and isolated infestations developed
in Thomas and Cheyenne Counties, but there have been no serious depre-
dations anywhere in the State.
Kansas. H. R. Bryson (July 27): M. bivittatus Say and M. differentialis
Thos. are not so plentiful this year. (July 24): Pardalophora halde-
manii Scudd. flew to the lights in the city of Manhattan and caused
considerable annoyance. They were plentiful from July 3 to July 15
and were most numerous on July 13. A similar flight occurred at Wake-
field on July 15.
Oklahoma. C. F. Stiles (July 22): Grasshoppers of various species are
appearing in large numbers in some of the central counties of the
State and also in practically all of the northwestern counties that
were so hard hit by the drought last year. The center of infestation
seems to be in Roger Mills, Ellis, and Major Counties. M. mexicanus,
the species that usually causes most of the damage in Oklahoma, is
quite numerous. Some poisoning is being done.
Idaho. C. Wakeland (July 24): Grasshoppers are moderately abundant in
a few localities of Gem and Washington Counties and Federal grass-
hopper bait is being used for control. Populations are very low in
the rest of the State and we have had no reports of control being
Utah. G. F. Knowlton (July 11): Warrior grasshoppers (C. nellucida)
have hatched out in considerable numbers in meadow land G miles north
C. J. Sorenson (July 20): C. pellucida is moderately abundant
in Ceche and Millard Counties. Nymphs of another species were very
abundant on June 26.
Oregon. D. C. Mote (July): All leaves of second-stand alfalfa on 65
acres at Oakridge have been consumed by nymphs.
MORMON CRICKET (Anabrus simplex Hald. )
Idaho. C. Wakeland (July 24): The most interesting thing to report this
nonth is parasitization of the Mormon cricket by the hairworm Gordius
villoti Rosa. Farmers are of the opinion that about 50 percent of the
crickets They mashed when destroying them around their gardens con-
tained hairworms, but when I investigated last week I found that only
1 cricket out of 300 dissected was parasitized. However, dead crickets
were numerous in the streams and apparently the cycle of Gordius had
already been passed inside the cricket bodies.
EUROPEAN EARWIG (Forficula auricularia L.)
Rhode Island. L. H. Worthley (July- 15): Weather conditions have proved
ideal for this species and heavy infestations have occurred in Newport
County. An eradication campaign is under way.
Nebraska. M. H. Swenk (July 15): The variegated cutworm (LycoDhotia
margaritosa saucia Iibn.) was present in outbreak proportions from
June 19 to 27. Damage was chiefly in the alfalfa, corn, and potato
fields and in the gardens of southeastern Nebraska. After the close
of this outbreak a later isolated outbreak occurred in the alfalfa
fields of central Nebraska from July 5 to 10. In Loup County these
cutworms took as high as 25 percent of the alfalfa in several fields
before the poisoned-bran bait could be used to check them.
California. A. E. ichelbacher (July 22): The yellow-striped armyworm
(Prodenia praefica Grote) was very abundant at Vernalis on July 19.
In one alfalfa field at least it was doing considerable damage. .The
feeding was heavy enough to be observed at some distance.
ARMYWORM (Cirphis unipuncta Haw.)
Ohio. E. W. Mendenhall (July g): The armyworm is very destructive to
rye fields and meadows in Champaign and Madison Counties.
Indiana. J. J. Davis (July 24): Armyworms have been reported from prac-
tically all sections of the State. The reports from June 24 to July 3
came from the northern half. Timothy, wheat, rye, and corn are the
Iowa. H. E. Jaques (July 22): Armyworms are still in evidence but danger
of serious damage seems to have passed. An unusual abundance of
-iis ~~is fe teot-adn
Archytas analis Fab. is being found. As this is often the outstanding
parasite of the armyworm in this part of the country, its abundance
indicates a great reduction in the number of armyworm moths.
Missouri. L. Haseman (July 22): Moths of the armyworm are now on wing,
feeding on the juice of over-ripe peaches and apples.
Nebraska. M. H. Swenk (June 30): The outstanding insect pest of the
second half of June was the true armyworm, of which many complaints
of damage to rye, wheat, corn, and alfalfa were received. These re-
ports of damage came chiefly fro:m the southeastern corner of the State.
In many cases the damage was serious, although there were but few in-
stances of migration.
FALL AlRMYORM (Laphygma frugiperda S. & A.)
Mississippi. C. Lyle (July 23): An outbreak of the southern grassworm
is occurring in the southern part of the State. Specimens have been
receivedfrom Liberty, in Amite County, and from Sandy Hook, in Marion
County. One correspondent reported that corn in some fields had been
reduced to stubs.
BERTHA ARMYWORM (Barathra configurata Walk.)
North Dakota. J. A. Munro (July 28): There are spotted infestations in
the central part of the State. Near Jamestown, in Stutsman County, in
a 75-acre field of flax, 35 acres had already been stripped on July 25.
The worms were invading the remainder. Another 30-acre flax field near-
by showed only slight damage an'. light infestation. On July 27 we
looked over several fields of flax northeast of Bismarck, in Burleigh
County. The damage ranged from a negligible amount to complete de-
struction. We saw an gO-acre field of flax that was completely stripped.
On July 28, one 30-acre field of flax, northwest of Mandan, in Morton
County, had a patch of 7 or 8 acres destroyed, and the worms were work-
ing into the remainder. Other fields inspected showed less injury.
Examinations to date have shown the worms to be most abundant in weedy
flax fields. In one field near JEaestown natural mortality of the army-
worms ranged from 25 to 70 percent in different parts of the field,
averaging about 40 percent. The cause of the mortality was not deter-
mined but is believed to be due to the combined attack of disease and
Wisconsin. E. L. Chambers (July 23): Wireworms were unusually injurious to
corn, onions, potatoes, and other crops planted on heavy black soil, es-
pecially where drainage was poor, in Milwaukee and Kenosha Counties.
Nebraska. M. H. Swenk (July 15): On June 25 the upland corn wireworm
(Melanotus pilosus Blatch.) was found working in young corn in Mer-
rick and Lancaster Counties. This pest was complained of as destroy-
ing onions in Grant County on June 2G. On July 6 the wireworm was
found badly injuring a potato field in Antelope County.
Kansas. H. R. Bryson (July 27): Monocrepidius sp. reported injuring
potato tubers and the roots of tomatoes at Peru on June 25.
Washington. M. C. Lane and H. P. Lanchester (July): Severe injury by
Pacific coast wireworms (Pheletes canus Lec.) to spring onions and
cantaloup has been noted in several fields near Walla Jalla during
the past month. In one cantaloup field over 20 percent of the hills
were totally destroyed. Careful damage counts showed from 8 to 15
percent of the onions culled out for injury in one field alone.
K. E. Gibson (July 18): An investigation in the district near
Sunnyside showed that where it had been necessary to makce a second
seeding of sugar beets, the first seeding having failed because of ad-
verse weather conditions, the second planting had, in many instances,
been heavily damaged by wireworms. A number of tracts of sugar beets
of from 3 to 5 acres had been destroyed.
A WEEVIL (Myllocerus castaneus Roelofs)
New Jersey. A. C. Davis (June 30): On June 30 three specimens of this
weevil were taken a short distance from Montclair. One was beaten
from wild grape, another from oak, and the third from ash(?). The
insect seems to be a general feeder. (Det. by L. L. Buchanan.)
(This species was first collected in the United States in August 1933
at Montclair. It was originally described from Japan in 1873. In
1884 it was recorded from Russian Siberia. Practically nothing is
known of the habits of this species but it bclongs to a large genus
of over 90 species. The greater number of the species are in India
and the East Indies, a few are in: Africa, and one in Australia. One
species, M. blandis Boh., is a serious pest of cotton'in Punjab, India.
The different species of the genus are known to feed on a wide variety
of food plants of which L-W 'have been recorded and among which may be
mentioned such plants as cotton, tobacco, eggplant, potato, grapefruity
apple, sugarcane, tea, and cacao.)
JAPANESE BEETLE (Popillia japonica Newm.)
General. C. H. Hadley (July 30): The outstanding feature of the current
beetle season is the very marked increase of the infestation and the
severit-r of feeding on foliage, as compared with those of a year ago.
Within the central part of the main area of infestation, where the
insect was first found and in which it has been
longest established, the beetle population is noticeably heavier than
during the past several years, although not as yet reaching the peak
infestations of 1924-27. In general, around the periphery of the area
of heaviest infestation, the beetle population considerably exceeds
that of the est several seasons. The increase in abundance has also
been especially noticeable in the large metropolitan areas of New
York, Brooklyn, Philadelphia, Wilmington, and Baltimore. Beyond the
main area of heavy beetle infestation, reports indicate that there is
a corresponding increase in the population at points of local infes-
tation. Injury to vegetation is noticeable this year for the first
Rhode Island, Massachusetts, and Connecticut. L. H. Worthley (July 15):
State Japanese beetle traps in Rhode Island began catching beetles on
July 2. By July 9 over 400 beetles had been caught, 262 being found
on one property. Eleven beetles rwere caught in 25 traps set in South
Boston, the first catch having been made on July 13. At Springfield,
Mass., the first beetle was taken on July 1, end at Norwich, Conn.,
on July 3.
Connecticut. W. E. Britton (July 23): Adults have been more abundant
than ever before in certain localities in Bridgeport, Hartford, and
New Haven, and have caused some injury to plants.
New York. L. H. Worthley (July 29): Scouting for the Japanese beetle
in nurseries and greenhouses in the Syracuse area was started on
July 12. On July 15 discovery was made of a first-record infestation
at Glens Falls, in Warren County. The scout crew collected 3L
beetles within 300 feet of nursery premises in that city.
New York and New Jersey. M. Kisliuk, Jr., and E. Kostal (July 8): The
first few adults of the Japanese beetle made their appearance on milk-
weed and ragweed in Jamaica, L. I., N. Y., on July 1, and on rose at
Morganville, N. J., on June 29.
Delaware. L. A. Stearns (July): Adults present in great numbers and caus-
ing wide-spread injury around Wilmington; apparently near the peak of
infestation for this district.
Maryland. E. N. Cory (July 24): Japanese beetles being reported quite
frequently from the Baltimore area.
ROSE CHATER (Macrodactylus subspinosus Fab.)
Maine. H. B. Peirson (July): Reported in central and southern Maine in
June and July. Adults swarming and feeding abundantly on apple (es-
pecially the young fruit), red maple, silver maple, cherry, elm,
alder, woodbine, phlox, daisies, corn, and beans.
Maryland. E. N. Cory (July 24): Early in June there was a heavy infes-
tation of rose chafers.
Wisconsin. E. L. Chambers (July 23): Rose chafers have defoliated every-
thing in their path in portions of Shawano and Monroe Counties.
A CHINCH BUG (Blissus hirtus Montd.)
New Hampshire. L. C. Glover (July 24): There have been a few reports of
injury to lawns b"r chinch bugs.
Ohio. J. S. Houser (July 23): Despite abundant rains and copious arti-
ficial watering this chinch bug is thriving and numerous young are
ap-earing at Cleveland. Dead patches in lawns have begun to appear.
SAY'S STINK BUG (Chlorochroa sayi Stahl)
California. H. J. Ryan (July 1): Say's plant bug was noted during the
week of June 16 in considerable numbers on the south side of the Ante-
lope Valley in a strip extending iabout 5 miles east and west of Palm-
dale, traveling across and through the sagebrush. Adults were in
evidence flying from plant to plant, always in the direction of the
foothills to the south, where great numbers of half-grown bugs were
wandering aimlessly on the ground or resting on the plants. There
are a few pear orchards in the line of travel, but no damage has been
found in any of them.
COMMON RED SPIDER (Tetranychus telarius L.)
Maryland. E. N. Cory (July 24): The red spider is exceedingly numerous.
Georgia. 0. I. Snapp (May 31): Very abundant and has seriously injured
beans and other vegetables at Fort Valley. Mayr has been an unusually
Florida. J. R. Watson (July 22): Red spiders have been rather common on
Ohio. N. F. Howard (July 23): Red spiders are becoming increasingly
abundant on a variety of hosts in Columbus, viz.; soft maple, flower-
ing beans, gardlen beans, and ornamentals.
E. W. Mendenhall (July 20): The red spider has been very injurious
to raspberry plants near Carroll, in F&rfield County.
Indiana. J. J. Davis (July 24): On June 27 red spiders were destructive
to beans and corn at Cedar Grove.
Nebraska. M. H. Swenk (July 1 to 15): Che of the more outstanding pests of
the period has been the red spider. Although many plants were attacked,
the most complaints concerned red raspberries, currants, beans, and
Kansas. H. R. Bryson (July 27)4 Red spiders have been unusually destructive
during the past month on large American elms, vegetables, ornamental
shrubs, grasses, and weeds.
Oklahoma. F. E. Whitehead (July 22): The red spiier, which customarily
apnears in dry hot spells, is much worse than usual this spring, and
in the vicinity of Stillwater a large variety of plants has been
severely injured. Reports from over the State indicate that the in-
festation is more or less general.
Idaho. R. W. Haegele (July 22): In a few places the common red spider
increased to injurious numbers during July.
Utah. G. F. Knowlton (July 22): Red spiders are damaging raspberries.
Oregon. D. C. Mote (July): Two-spotted mites at Milton and Freewater.
Considerable injury on prune foliage.
CEREAL AND FOR AGE-CROP INSECTS
WHEAT AND OTHER SMALL GRAINS
HESSIAN FLY (Phytophaga destructor Say)
Ohio. T. H. Parks (July 25): Hessian fly increased greatly during the
spring, but was not responsible for heavy loss in yield. Most of the
infested straws remained standing and there was usually one flaxseed
per straw. The heaviest infestation was found in Seneca County, where
54 percent of the straws were infested. The infestation was heaviest
in counties having the most early sown wheat.
J. S. Houser (July 23): There has been a sharp increase in
hessian fly abundance in Ohio this season. Some very heavily infested
fields have been found. In some fields examined many of the flax-
seeds are located high up on the straw.
Oklahoma. C. F. Stiles (July 22): Quite heavy infestation has been re-
ported at Jefferson in Grant County.
WHEAT STEM MAGGOT (Mero-rza ammericana Fitch)
North Dakota. F. D. Butcher (July 17): Traces of the wheat stem maggot
were observed in several wheat fields in Dickey and Ransom Counties.
In a rye field in which the white heads were conspicuous, a count re-
vealed 1 percent of the straws attacked.
BLACK GRAIN-STEM SAWFLY (Trachelus tabidus Fab.)
Ohio. J. S. Houser (Julyr 23): This insect has extended its range in Ohio
this year, having been found as far west as Wooster and 33 miles north
of Marietta. Some heavily infested fields in Liahoning and Columbiana
Counties. Because of the heavy stand, infested wheat did not lodge as
severely as did the fields with thin stands in 1931. From last year's
observations, as well as from those of this season, this insect bids
fair to become a major wheat pest.
GRASS THRIPS (Anaphothrips obscurus Mull.)
Ohio. N. F. Howard (Jul'- 23): Oat bugs are very numerous as oats are
ripening and being cut and are very annoying to rural residents.
Indiana. J. J. Davis (July 24): The oats bug has been especially abun-
dant and annoying in the northern half of the State, where it is not
an annual event. Definite reports of unusual abundance have come
from Bluffton, Portland, Winchester, LaFayette, and Monticello.
CHINCH BUG (Blissus leucopterus Say)
Ohio. T. H. Parks (July 25): Until the second week in July rains killed
chinch bugs nearly as fast as they hatched. Since that time isolated
farms have been infested with migrating late-hatched bugs that have
not done serious damage because the corn was well along. In one
western Ohio area that was missed by most of the rains the bugs have
been marching into cornfields since July 10. Barriers have been nec-
essary in this area and on isolated farms in 10 other counties. The
bugs are now almost out of the wheat stubble.
Indiana. J. J. Davis (July 2L4): Chinch bugs have been persistent, not-
withstanding adverse weather conditions. In the areas along the west
side of the State, where the heaviest infestctions occurreC in 19314,
the bugs have been largely wiped out. This, perhaps, was largely due
to the white-mold fungus. The bugs in this region went into winter
quarters in superabundance, but were evidently weakened from scarcity
of food due to drought; then followed wet weather last spring. Thus
the old bugs were emaciated and, with the high humidity, most of them
succumbed. In the eastern part of the State the bugs were not ema-
ciated, they were not so crowded in their winter quarters, and, not-
withstanding excessive moisture, the white-mold fungus was not a
significant factor. However, the continuous driving rains have held
the young bugs in chocdi and even in areas where they still continue
in large numbers, they are not i.Iigrating freely because of excessive
grassy growths in grain stubble. If we have normal weather the re-
mainder of the season we can anticipate an appreciable amount of
damage by the second generation of bugs and throuihout the northern
two-thirds of the State a carryover of bugs that would threaten the
Illinois. W. P. Flint (July 24): Wet weather has continued during July
and reduced the chinch bugs to such an extent that migration from
small-grain fields to corn occurred in less than 1 percent of the
small-grain fields. The only areas where any general migrations oc-
curred were sand areas in the northwestern and southeastern parts of
the infested section of the State.
Wisconsin. E. L. Chambers (July 23): No appreciable damage was observed
to small grains and very little migration into cornfields reported as
grain is being cut.
Iowa. C. J. Drake (July 20): Chinch bug migration is still in progress.
A little danage is being done in cornfields. In most cases farmers
have erected barriers. The infestation is confined to the eastern por-
tion of the State, being heaviest from Cedar Rapids to.Clinton and
south to Burlington. In the fall of 1934 many farmers planted rye.
Late this spring many of the rye fields were plowed under and planted
to corn. Wet weather kept quite a number of the rye plants alive and
they afforded suitable breeding places for chinch bugs. As a result,
much of the corn planted in the turned-under rye fields is infested
Missouri. L. Haseman (July 22): Continued rains held back breeding and
so reduced first-brood bugs that, except for occasional pastured fields
of rye and wheat, bugs were too scarce at wheat harvest to cause any
anxiety. Barriers were constructed in three or four northeastern
Kansas. Although chinch bugs were found in the eastern part of the State,
they were not numerous enough to warrant the construction of barriers.
CORN EAR WORM (Heliothis obsoleta Fab.)
Connecticut. N. Turner (July 22): Only one half-grown larva seen thus
far in southern Connecticut. Less abundant than last year. Reported
as present at Derby.
Maryland. E. 7. Cory (July 24): The corn ear worm seems to be building
Virginia. H. G. Walker and L. D. Anderson (Jul- 26): Moderately abundant
on tomatoes and from moderately abundant to very abundant on field and
sweet corn in the vicinity of Norfolk.
South Carolina. F. Sherman (July 1S): Infest.tion in tomatoes has been
above normal, but it is now decre-sing as nearby corn silks become
Ohio. H. C. Mason (July 20): The tomato fruit worm is causing considerable
injury to tomatoes at South Point, but is not as serious as in 1934.
E. W. Mendenhall (July 17): The tomato fruit worm is very in-
jurious in southwestern Ohio, doing severe damage to tomatoes.
Illinois. W. P. Flint (July 24): No reports of damage from the corn ear
worm have been received to date.
Iowa. C. J. Drake (July 29): The corn ear worm is fairly abundant in the
southern half of the State. Considerable damage has been noted in
Marshall and Story Counties.
Missouri. L. Haseman (July 22): The first generation has been showing up
STATE PLANT R A na
in the tassel end of young corn and a few complaints have already been
received where it is working in early sweet corn.
Arkansas. D. Isely (July 20): Injury by the corn ear worm is unusually
light for the latter part of July.
Kansas. H. R. Bryson (Jul- 27): The corn ear worm injured early sweet
corn quite severely, although the injury did not appear quite so severe
as in other years. A report of ragvorm injury was received from Summer-
field. Many local reports of injury to tomatoes. Reports of serious
damage to tomato fruits were received from Marquette, Alma, anc. White
Oklahoma. F. E. Whitehead (Jul- 22): The corn ear worm is infesting ap-
proximately 100 percent of the sweet corn in the vicinity of Stillwater
end is extremely common in other varieties.
Idaho. R W. Haegele (July 22): The corn ear worm is very common this
year in the southwestern part of the State. Sweet-corn ears are 50
percent infested and the larvae are feeding on the tassels of late-
planted field corn. Many larvae are full grown and are leaving the corn.
Utah. G. F. Knowlton (July 22): Corn ear worms are now beginning to attack
sweet corn at Logan. Worms are moderately abundant in tomato fruits
in Utah County. The largest caterpillars are now one-third grown.
STALK BORER (Papaipema nebris nitela Guen.).
New York. C. 2. Crosby (July 11): Specimens received from Massena, where
they were attacking tomato plants.
Indiana. J. J. Davis (July 24): The stalk borer was reported damaging
sweet corn at Campbellsburg on July C. This is the only authentic re-
port to date.
Kentucky. W. A. Price (July 29): The common stalk borer has been the
cause of many complaints by flower andc vegetable growers, -
Kansas. H. R. Bryson (July 27): Common stalk borer reported doing some
local injury to corn at Lebanon.
EUROPEAT CORN BORER (Pyrausta nubilalis Hbn.)
Connecticut. N. Turner (July 22): Pupation is general. In early sweet
corn on one farm from 60 to 75 percent of the ears were infested. The
infestation in Hartford County does not seemr quite as heavy as last
year, although no figures are available. Damage has increased -in the
southwestern part of the State. Borers are more abundant in the north-
western section but are not causing -much damage as yet.
New York, N, Y. State Coll. Agr. News Letter (July 15): The corn borer
is working on the tassels of early sweet corn in Suffolk County, but
was not observed in destructive numbers on potatoes, as occurred
last year around the Southold area. The borer is doing considerable
damage in iTassau County.
Virginia. H. G. Walker and L. D. Anderson (July 26): About SO percent
of the larvae placed in an outside hibernation screen cage last fall
at Onley, Accomac County, completed their development and emerged
as adults this spring. Pupation began the latter part of April and
several moths had emerged by May C. On May 15 these moths began lay-
ing eggs which hatched on May 27. Larvae hatched on June 6 pupated
on July 3, proving that the two-generation form is the one present
here. The first moths of the second generation emerged in our breed-
ing cages on July 10 and began laying eggs on July 13. Field ob-
servations indicated that the borer completed its life history as
early or earlier in the field than in our cages.
SOUTHERN CORN STALK 3ORER (Diatraea crambidoides Grote)
Maryland. E. N. Cory (July 23): The southern corn stalk borer is attack-
ing corn at Leonardtown.
Virginia. H. G. Walker and L. D. Anderson (July 26): The larger corn
stalk borer is very abundant and many fields of corn around Norfolk
are being injured.
Alabama. J. M. Robinson (July 20): The larger corn stalk borer is
moderately abundant at Fairfax, Attalla, and Auburn.
LESSER CORN STALK BORER (Elasmopalpus lignosellus Zell.)
Maryland. E. N. Gory (July 24): Lesser corn stalk borer attacking corn
Alabama. J. M. Robinson (July 20): The lesser corn stalk borer was re-
ported as attacking peanut vines in Houston County, as well as being
moderately abundant on corn in the southeastern part of the State.
SOUTHERN CORN ROOT WORM (Diabrotica duodecimpunctata Fab.)
Ohio. T. H. Parks (July 25): Corn root worm larvae have been causing
injury to corn in a field in Licking County. Some of the plants
have fallen over as a result of the feeding.
Illinois. W. P. Flint (July 24): The southern corn root worm has caused
an enormous amount of damage throughout the west-central counties
of Illinois. Beetles were unusually abundent in the spring, and
many fields of corn in that section are now virtually destroyed.
Kentucky. W. A. Price (Jul-, 29): The southern corn root worm has been
more destructive to corn than usual.
Missouri. L. Haseman (July 22): The southern corn root worm has been
doing much damage to corn during the past 2 or 3 weeks. The beetles
have been injuring late-planted cucumbers and squashes in central
CORN SILK BEETLES (Luperodes spp.)
Alabama. J. M. Robinson (July 20): The corn silk beetle/L. davisi Leng
was active on :corn silks and cotton leaves in Covington and Geneva
Mississippi. C. Lyle (July 23): Specimens of L. varicornis Lee., re-
ported as injuring young corn, were received from Puckett, in Rankin
County, and inspector I. D. Peets states that serious injury has oc-
cu rred in Lincoln County.
CLOVER AND ALFALFA
ALFALFA WEEVIL (Hypera postica Gyll.)
General. G. I. Reeves (July): In the course of our scouting operations
in June, the alfalfa weevil was found in Sioux and Scotts Bluff Coun-
ties, Iebr.; Montezuma County, Colo.; Kane County, .Utah; Clark County,
Nev.; Coconino County, Ariz.; Mali'eur, Baker, and Union Counties, Oreg.;
and in Mendocino County, Calif.
Utah. C. J. Sorenson (July 20): The alfalfa weevil is moderately abundant
in Juab, Millarc, Box Elder, and Cache Counties.
California. A. E. Michelbacher (July 22): Through the-infested area of
lowland in-central California the larvae of the alfalfa weevil can be
collected easily. On July 18 the numbers of larvae collected per 100
sweeps of an insect net ran as high as 75. Parasitization by Bathy-
olectes curculionis Thois. has fallen off rather rapidly. At Pleasanton
on July 10 about 10 percent and at Niles 13 percent of the large larvae
were parasitized. ITo infested larvae of the alfalfa weevil were found
in the San Joaquin Valley.
PLANT BUGS (Lygus elisus Van D.)
Utah. C. J. Sorenson (July 20): Lygus elisus Van D. and var. hesperlus
Knight are moderately abunc'.:nt over the entire State, chiefly in
ALFALFA LOOPER (Autographa californica Speyer)
Wyoming. C. L. Corkins (July 9): We are now having considerable diffi-
culty with the alfalfa semilooper in Park County. Following the
cutting of alfalfa, these worms are migrating into bean fields, where
damage in some instances has been severe before control measures could
Oregon. D. C. Mote (July): Newly hatched larvae of the second genertion
are occurring in Willamette Valley. First-brood worms injured beans,
corn, squash, and seedling alfalfa.
CODLING MOTH (Carpocaosa pomonella L.)
New York. P. J. Parrott (July 23): The codling moth is moderately abun-
dant about Geneva, and is very abundant in Niagara, Orleans, and
N. Y. State Coll. Agr. News Letter (July 22): Codling moth in-
jury is becoming more noticeable in the orchards in western New York.
Delaware. L. A. Stearns (July 23): There were two peaks of activity of
spring-brood moths as indicated by bait pans--May 28-29 and June 17-
S1. First-brood attack was considerably lighter than usual. First
first-brood moths appeared on July 8. Ho serious second-brood injury
reported as yet.
Georgia. C. H. Alden (July 22): Injury to apples by first-brood worms
is becoming more abundant at Cornelia and' Thomaston but is not as
heavy as in 1934. Broods are now overlapping, so that continuous
fresh stings are being noted.
Ohio. T. H.Parks (July 25): Growers report less injury than usual from
first-brood larvae. Well-sprayed orchards show very few codling moth
blemishes. Bait pans are not catching many moths.
J. S. Houser (July 23): First adults of summer brood emerged at
Wooster on July 23.
Indiana. L. F. Steiner (July 23): The effect of cool, rainy weather on
the amount of injury by first-brood larvae is well illustrated at
Bicknell. In 19314. the first pick-up of drop fruit early in June av-
eraged 600 successful entrances per tree and by harvest time trees
that had had intensive spraying produced an average of 3,500 worms
each. Despite a larger cron this season, fewer and less thorough
spray applications than in 1934, and a lighter residue load, drop
fruits are so scarce that no pick-up had been justified. Worm en-
trances are almost impossible to find, yet stings are fairly abundant.
It is very evident that the vitality of first-brood larvae this season
was much less, when they attempted entrance, than in 1934 and that
considerably lighter deposits of ooison were needed to effect the
same degree of control.
D. W. Hamilton (July 21): At Orleans practically all adult
activity of the spring brood had ceased by July 2. First-brood larvae
began pupating under bands between June 26 and July 3. Daily captures
in light and bait traps began picking up the night of July 16, indi-
cating that first-brood adults were emerging in the orchard.
Illinois. W. P. Flint (July 24): Codling moths continue to be scarce in
most areas but there is a distinct increase in the infestation.
Michigan. R. Hutson (July 11): The first-brood codling moth has been
very late and straggling in its appearance. Flight peaks occurred on
June 22 in 3er:-ien County; on Jul, 1 at Hrtfordc, in Van Buren County;
and on July 2 at Mason, in Ingham County.
Wisconsin. C. L. Fluke .(July 22): First brood very light at Madison;
maximum flight of second brood not expected until the second or third
week of August.
Missouri. L. Haseman (July 22): The unusual season spread the spring
brood of moths in southern Missouri over a 2-month period and in cen-
tral and northern Missouri emergence was delayed nearly 3 weeks. How-
ever, few of the early moths in southern Missouri succeeded in leav-
ing offspring. As a result, second-brood moths all over the State
are appearing uniformly in two bunches.. The first bunch emerged be-
tween July 15 and 20 and the second and probably the larger bunch is
expected between July 25 and early August. Generally speaking, spray
control, combined with the weather, has been very effective against
Arkansas. D. Isely (July 20): The codling moth infestation is later and
lighter than it has been since 192g.
Oklahoma. F. E. Whitehoad (July 22): The codling moth is present in about
its usual numbers, taking a large toll of the apple crop.
Washington. E. J. Newcomer (July 25): Moths of the first brood began
emerging at Yakima about July 12. This is 3 weeks later than in 1934.
The infestation is lighter this year than last, owing to continued
cool weather during May and June.
Oregon. D. C. Mote (July): First-brood moths are not out yet. Highest
infestrtion for several years.
California. S. Lockwood (July 24): Pear growers in the Sacramento River
area below the City of Sacramento are receiving more loss from the
codling moth this year than for many years.
APPLE MAGGOT (Rhagoletis pomonella Walsh)
Connecticut. P. Garman (July 22): Flies emerging in fair numbers. Pros-
pects of a heavy-to-moderate infestation.
New York. P. J. Chapman (July 22): The emergence of flies in the Hudson
Valley is later than in 1933 and- 1934. Indications are that the peak
of emergence had not been reached up to and including July 19, but
should occur by July 24-26 in that area. During the past two seasons
the peak has occurred approximately fion July 15 to 17.
New Jersey. M. Kisliuk, Jr., and E. Kostal (July.8): The first adult was
observed on an apple leaf at Morganville on July 2.
Michigan. R. Hutson (July 11): Adults were captured at Lawton and South
Haven on July 7, and at Elk Rapids o-n July 9.
Wisconsin. C. L. Fluke (July 22): -The first adult emerged at Gays Mills
July 15, about 10 days later than the average date in previous years.
APPLE FLEA WEEVIL (Orchestes pallicornis'Say)
Ohio. T. H. Parks (July 25): Many orchards have a great deal of flea
weevil injury. Two orchards near Delaware now show very serious in-
A SCARABAEID (Trichiotinus bibens Fab.)
North Carolina. C. H. Brannon (July): This species 'is causing consid-
erable injury to apples in several mountain counties.
PLUM CURCULIO (Conotrachelus nenuphar Hbst.)
Connecticut. P. Garman (July 22): The plum curculio is less abundant
Delaware. L. A. Stearns (July 23): Maximum emergence of first-brood
adults July 8; about 25 percent of dissected females contain fully
developed eggs; the usual partial second brood will probably develop
in southern Delaware.
Virginia. W. J. Schoene (July 23): During the past fewv weeks adults
have been found in unusual numbers' in peach orchards in the Roanoke
section. Some of the females were found to contain fully developed
Georgia. 0. I. Snapp (July 20): The very dry weather at Fort Valley
during the last month prevented the new beetles from depositing many
eggs, and, as a result, the peach crop was harvested without much
damage from second-bro6d larvae. An unusually heavy emergence of first-
generation adults occurred.this year and the peach crop -ould have en-
countered a serious second brood had the weather been normal. There
is now an unusually large population of first-generation adults in
peach orchards and, since these have not deposited many eggs this year,
a heavy early infestation is predicted for 1936.
C. H. Alden (July): Some orchards at Thomaston showed infesta-
tions as high as 25 percei.- at harvest time, while others ran as low
as 3 percent. Fruit has not. yet been harvested at Cornelia but so
far the infestation is running less than 5 percent in Georgia Belle
Mississippi. C. Lyle (July 23): Very severe damage to peaches ripening
in July has been reported from practically. all sections of Mississippi.
Missouri. L.-Haseman (July 22): This pest was slow in showing up, but
recently many plums and peaches have been showing nearly mature lar-
ORIENTAL FRUIT MOTH (Grabholitha molesta Busck)
Connecticut. P. Garman (July 22): The first generation is unusually
scarce; second generation much delayed, and scarce in most orchards
of the State.
Delaware. L. A. Stearns (July 23): Parasitization of first-brood twig-
infesting larvae shova decline approximating 30 percent from that of
1934. Second-brood twig-infesting larvae are now practically mature.
Injury has increased, owing to lower parasitization, and considerable
infestation of peaches and apples by later broods seems probable.
South Carolina. .W. C. Nettles (July 18): The oriental fruit moth is be-
low normal in destructiveness.
Georgia. C. H. Alden (July 22): The fruit moth has not been a factor
this year at Cornelia and Thomaston. Fruit scored in central Georgia
showed about 2 percent inestation, as cormpared with 18 percent in
Indiana. L. F. Steiner (July 23): More adults have been coming to codling
moth traps during the past week than any previous week this season.
Illinois. W. P. Flint (July 24): The oriental fruit moth is more abundant
than in any year for the last 3, and large numbers are now going into
Tennessee. G. M. Bentley (July 22): The third brood of the oriental fruit
moth is making its appearance. The situation is.generally bad over the
Mississippi. C. Lyle (July 23): Many complaints of the oriental peach moth
have been received during the month. All plant board inspectors are
reporting serious injury to peach twigs.
PEACH BORER (Aegeria exitiosa Say)
Virginia. W. F. Turner (July 19): The peach tree borer is extremely abundant
and obviously injuring the trees at Crozet., Three full-grown borers were
found in one 6-inch section of root ( inch thick, about 2-7 feet from
the trunk. From 10 to 12 full-grown borers were found in many trees.
One tree had 17 borers.
Georgia. 0. I. Snapp (July 20): Pupation is beginning generally in com-
mercial peach orchards around Fort Valley. Twenty-nine cocoons were
taken during an examination of 100 trees on July 18.
Indiana. J. J. Davis (July 24): The peach tree borer was reported attack-
ing peach at Mishawaka early in July.,
PEACH TWIG BORER (Anarsia lineatella Zell.)
Utah. C. J. Sorenson (July 1): Specimens collected at Farmington in June.
California. H. C. Donohoe (July 1): Apricots picked in an orchard at
Orland in which no control was practiced this spring were examined on
June 24 while being cut for drying. Over 50 percent of the fruits were
infested by the peach twig borer.
GREEN STINK BUG (Acrosternum hilaris Say)
California. S. Lockwood (July 24): In the last 3 weeks the southern half
of the San Joaquin Valley has been overrun with plant bugs. These
have for the most part been A. hilaris, followed by much smaller num-
bers of Chlorochroa sayi Stahl and by even fewer Thyanta custator Fab.
Considerable damage has been done to canning peaches in some rather
small areas. In one section between 40 and 50 acres of peaches have
been absolutely ruined and the fruit will not be picked. Reports from
other areas state that these insects are quite numerous in cotton
fields, where they are causing the young squares to drop, and are also
puncturing cotton leaves.
PLANT BUGS (Lygus spp.)
Connecticut. P. Garman (July 22): Some orchards severely damaged, partic-
ularly those with a light set of fruit; damage most severe in Glaston-
bury district, Hartford County.
PEAR PSYLLA (Psyllia pyricola Foerst.)
Connecticut. P. Garman (July 22): Pear psylla abundance is the same as
last month in New Haven County.
New York. N. Y. State Coll. Agr. News Letter (July 22): The pear psylla
is causing serious damage in some orchards in western New York.
CHERRY FRUIT FLY (Rhagoletis cingulata Loew)
Michigan. R. Hutson (July 11): The white-banded cherry fruit fly appeared
at Traverse City on July 2 and at Elk Rapids on July 9.
Oregon. D. C. Mote (July): R. cingulata emergence, June 3; oviposition,
June 13; hatching, July 11, in the field.
CHERRY LEAF BEETLE (Galerucella cavicollis Lec.)

from two counties, Garrett and Allegany. (Det. by H. S. Barber.)
West Virginia. F. W. Craig (August 1): Specimens were sent in from Hunting-
ton, in Cabell County, and from Pocalhontas County.
PEAR SLUG (Eriocampoides limacina Retz.)
New York. C. R. Crosby (July 10): Specimens received from Lima, where
they were attacking cherry.
T. Y. State Coll. Agr. News Letter (July): After several years'
vacation, the pear slug is skeletonizing neglected cherry trees and is
working some on pear in Monroe County. It was also noted on young un-
spra:red cherry trees in Niagara County.
Indiana. J. J. Davis (July 24): Cherry and pear slug reported as skele-
tonizing pear and cherry foliage at Tipton and Michigan City the last
of June. The infestation is general, at least in the northern half of
BOXELDER BUG (Leptocoris trivittatus Say)
Utah. G. F. Knowlton (July 19): Boxelder bugs were found to be feeding
on ripe dewberry fruits at Granger, Salt Lake County.
BLUEBERRY STEM BORER (Oberea myops Hald.)
North Carolina. C. H. Brannon (July 29): This species is attacking com-
mercial plantings of blueberries in Pender County, causing serious
damage to branches and twigs. (Det. by A. G. Boving.)
GRAPE LEAFHOPPER (Erythroneura comes Say)
Delaware. L. A. Stearns (July 23): Infestation subnormal; usual grape
leafhopper spray in early Julyr omitted in most vineyards.

received from Felton.
CURRANT APHID (Myzus ribis L.)
South Dakota. H. C. Severin (July 22): The currant aphid is unusually
abundant this year. This pest has actually been responsible for de-
foliating currant bushes for the first time to my knowledge in South
PECAN BUDMOTH (Gretchena bolliana Sling.)
Mississippi. C. Lyle (July 23): Injury due to the pecan budmoth from
Hernando on June 28 and from New Albany on July 20 has been reported.
Arkansas. P. H. Millar (July 13): I am enclosing a larva and a pupa taken
from black walnut at Leachville yesterday. These were attacking the
nuts principally at the points where two nuts touched each other.
Both pupae and larvae were exposed by separating the nuts from each
other. The larvae were apparently feeding on the green hulls of the
nuts. (Det. as Gretchena sp., presumably bolliana. C. Heinrich.)
PECAN LEAF CASE BEARER (Acrobasis juglandis LeB.)
Connecticut. E. P. Felt (July 24): The walnut case bearer (A. juglandis)
was reported as very abundant at Orange.
North Carolina. R. W. Leiby (July 1S): Rather severe damage was inflicted
this spring to pecan buds and twigs by the leaf case bearer at Elizabeth
City in the largest orchard in the State. The summer work of larvae
on the foliage is now beginning to appear.
A SCARABAEID (Pachystethus marginata Fab.)
Mississippi. H. Gladney (July 23): These'beetles were practically defoliat-
ing 5 acres of young pecan trees in Jackson County early in July. Such
severe injury had not been noticed in previous years.
PECAN APHIDS (Monellia spp.)
Mississippi. J. P. Kislanko.(July 23): Pecan trees in lower Perry County
were heavily infested with pecan aphids, M. costalis Fitch and.M. ni-
gropunctata Granovsky on July 17.
FRUIT FLIES (Anastrepha spp.)
Texas. N. O. Berry (Jul- 26): Within the past 2 weeks 1,533 specimens
were collected. Only 1 adult A. ludens Loew was taken in Matamoros,
Mexico. Trapping of the other species of fruit flies ordinarily taken
decidedly declined. There were 61 A. ,oallens Coq., 4 A. serpentina
Wied., and I A. fraterculus auct. (not Wied.) taken on the American
side of the Rio Grande. Peaches arriving in Matamoros were heavily in-
fested with larvae identified as Anastrepha so. (not ludens).
TRUC K CR 0 P INSECTS
ASIATIC GARDEN BEETLE (Autoserica castanea Arrow)
General. C. H. Hadley (July 30): The Asiatic garden beetle is unusually a-
bundant and destructive in the suburban areas around New York City, bcrh on
Long Island and in New Jersey. In addition to feeding on such ornam- ital
plants as asters, chrysanthemums, and dablias, feeding injury has been
heavy in vegetable gardens on beets, cariout, cabbage, peppers, and turnips.
C~RROT BEETLE (Ligyrus gibbosts DeGe)
.Indiana. J. J. Davis (July 24): Adult carrot beetles were reported from
Goshen on June 26 and from La Porte on July 6. They were attacking the

as doing serious injury to leaves of corn near Wakarusa.
TARNISHED PLANT BUG (Lygus pratensis L.)
Indiana. J. J. Davis (July 24): The tarnished plant bug has been abundant
since the last of June in northern Indiana, attacking celery and potato.
According to G. E. Gould, weediness of fields and surroundings is largely,
if not entirely, responsible for the heavy infestations.
Missouri. L. Haseman (July 22): The tarnished plant bug is unusually abundant
at this time, attacking flowers and most crops.
Utah. G. F. Knowlton (June 23): Tarnished plant bugs are causing potato tops
to wilt at Roy.

Florida. J. R. Watson (July 22); The leaf-footed bug seems to be unusually
abundant this year.
POTATO AND TOMATO
COLORADO POTATO BEETLE (Leptinotarsa decemlineata Say)
Ohio. B. J. Landis (July 20): First-generation adults were numerous, feeding
and ovipositing on potato, spring groundcherry, matrimony vine, and tobaoco.
Indiana. Jo J. Davis (July 24): Adults hadw destroyed 30 acres of tomatoes
at Vincennes by July 5, and were expected do more damage, as the insecti-
cides used had not given satisfactory conwrol,
Wisconsin, E. L. Chambers (July): The Colorado potato beetle, until the past
few years very abundant but scarcely reported last year as doing any serious
injury, is again on the increase and requires mucn attention to prevent crop
damage to potatoes and tomatoes in certain sections of the State.
Minnesota. A. G. Ruggles and C. E. Mickel (July 23): The Colorado potato
beetle is moderately abundant.
North Dakota. J. A. Munro (July 15): The Colorado potato beetle is moderate-
ly abundant in Bottineau and Cass Counties.
South Dakota. H. J. Severin (July 22): The Color-do p-itto beaetle has not
been troublesome for years, but apparently is bLildil:, up i:s numbers again.
Injury is severe ih spots.
TOMATO FT7;0RIM (Gnorimoschema lycopersice l.r usck)
Virginia. H. G. 4alker and L. D. Anderson (July 26): Leaf-mining larvae
were collected in tomato leaves growing in a greenhouse at Norfolk, and in
tomato and potato leaves growing in a field nearby. (Det. by C. Heinrich.)
California. J. C. Elmore (July 18): At La Mesa one field was generally in-
fested in both leaves and fruit. At El Cajon the -w i winter crop was just
going in, but an early garden crop was found to .b 7:&vily infested, largely
in the leaf-mining and folding condition. No iin~'tations were found at
Chula Vista, Severe commercial damage was reported on this date in 1934
in all of the tomato-growiri districts mentioned a'9,ve0 In Peter's Canyon,
the pinworm is common on the foliage of tomatoes but o inj:n'' _. the
fruit was observed. Less damage than leas yer a .

more attention this season than for several years. The injury is spotted,
but beans in many sections of the State have been severely injured.
Ohio. T. H. Parks (July 25): The Mexican ben beetle is very destructive
N. F. Howard (July 23): The Mexican'bean beetle is more abundant in
central Ohio than ever before, and garden beans have been destroyed or
seriously damaged in many instances. For the first time in history the
beetle has caused injury at Marion, where the abundance is not limited to
city gardens but is also prevalent in farm gardens considerably removed
from the city. E. C. Mason reports that at South Point all early beans
not treated were defoliated.
Indiana, J. J, Davis (July 24): The Mexican been beetle hrs been unusually
abundant this year, reports of abundance ar' destruction coming in every
day since July fron all parts of the State, Damage is reported for the
first time from Lake County in the extreme northwest corner of the State.
Iowa. C. J. Drake (July 29): An infestation of the Mexican bePn beetle has
bibeen'discovered te~tthe dentral 'part of the State at Newt9fn,Jasper County.

Tennessee. G. MI.Bentley (July 22): The Mexican bean beetle is generally
very injurious over the State where treatn.ents are not used.
J. Milan (July 19): The Mexican bean beetle is causing considerably
more loss at Clarksville this season than for several years, even with the
use of better ana -ore effective insecticides.
Alabama. J. iM Robinson (July 20): The beetle continues to be very abundant
over the infested part of !labama. The e6gs have continued to hatch
through July owing to rains end cloudy weather.
Mississippi. C. LyleI (Ju4f .2): Numerous complaints have been received dur-
ing July, although the beetle is apparently not attracting as much attention
as in June,
Utah. G. F. Knowlton (July 30): The Mexican bean beetle is seriously damaging
bean foliage at Moab and Castle Valley, in the southern part of Grand County.
WESTERN SPOTTED CUCUMER BBETLE (Diabrotice soror Lec.)
Oregon. D. C. Mote (July): The western spotted cucumber beetle is more a-
bundant on cucurbits in Willamette Valley than for several years. In-
dications are that canning beans will be injured.

Maryland. EL. .Cory (July 24): This scarabaeid has been taken-in- a number
of bean fields on the Eastern Shore.
A. W. Palmer (July 3): The beetles were collected at Cove Point, on
the bay shore about 5 or 6 miles north of Solomon's Island. They were
feeding voraciously on roses, coreopsis, hollyhock, and Japanese Iris.
POTATO LEEOPPER (Empoasca fabae Harr.)
Ohio. N. F. Howard (July 23): The potato leafhopper ta dbing considerable
damage to beans at South Point and is more abundant than at any time since
we have been making observations there.
B. J. Landis (July 20): On July 1 the potato leafhopper was breeding
in broad beans and doing considerable damage at Columbus.
A PENTATOMID (Euschistus servus Say)
Virginia. W. H. White (July 31): On July 26 we received from Burke, near
Fairfax, specimens of lima beans injured by the feeding of a pentatomid and
by a disease. The correspondent said that the damage was confined to the
pods and that the leaves were not affected. H. G. Barber determined the
insect as E. servus, and L. L. Harter, of the Bureau of Plant Industry,
determined the disease as pod blight caused by Diaporthe phaseolorum. It
-is apparent that the damage to the pods by the pentatomids was closely as-
sociated with the prevalence of the fungus, but it is impossible to state
definitely whether the severe reauction of the crop was due solely to the
activities of the insect or to a combination of insect and fungus injury.
PEA APHID (Illinoia pisi Kalt.)
New York. P. J, Parrott (July 23); The pea aphid was very abundant'in
western New York during the early part of July.
Wisconsin. E. L. Chambers (July): The pea aphid has been unusually abundant
and has done serious damage in many pea-growing sections of the State, but
has now practically disappeared, leaving both the early and late crops
greatly reduced in value.
Oregon. D. C. Mote (July): Pea aphids increasing in abundance at Scappoose,
noticeably on peas.
IMPORTED CABBAGE WOPRM (Ascia rapae L.)
Ohio. T. H, Parks (July 25): The cabbage worm is more abundant than usual
on cabbage near Cleveland.
N. F. Howard (July 23): The cabbage worm is becoming very abundant
in Sandusky County and growers are sufficiently alarmed to inquire about
control measures. This is quite the reverse of the situation a few
B. J. Landis (July 20): Extremely numerous at Columbus on kale,

Utah. G. F. Knowlton (June 29): Strawberry weevils emerging in one straw-
berry patch at Logan are 10 percent B. ovatus L. and 90 percent B. rugosos-
triatus Goeze. The relative numbers of the two species vary greatly, but
both are present in most patches.
PEPPER WEEVIL (Anthonomus eugenii Cano)
Florida. J. R. Vatson (July 22): The pepper weevil is destroying all buds
as rapidly as they are formed in the infested area in Manatee County.
Abandoned fields are being destroyed by the growers.
California. J. C. Elmore (July 18): One light infestation of pepper weevil
found at Santa Ana, Orange County. Other fields near Balsa, Talbert, and
Huntington Beach were not infested.
BEET LEAIHOPPER (Eutettix tenellus Bak.)
Colorado. We A. Shands and 0. A. Hills (July): At the end of June the beet
leafhopper populations were very high in the Grand Valley and Delta-Montrose
districts. Evidence of the curly-top disease began to appear early in June
and by the last of June the percentage of plants affected ranged from 30 to
50 percent, although in general the injury was not serious.
Idaho. R. V. Haegele (July 22): The tomato plantings of southwestern Idaho
have been almost entirely killed out by the blight caused by the beet leaf-
Utah. G. F. Knowlton (July 3): Curly top is becoming increasingly severe in
the Weber-Davis area. Some fields at Hooper are more than 60 percent af-
fected. Tomato fields have been plowed up at Kaysville and Layton.
(July ll)1 Curly top continues to increase in abundance. Already serious
losses of tomato plants have been sustained in many localities, with counts
showing as high as 80 percent diseased. Injury to sugar beets is gradually
increasing in many parts of northern Utah. (July 22): Curly top is taking
from 15 to 20 percent of the beans in some patches at Tremonton, Garland,
A ALISE CHINCH BUG (Nysius sp.)
California. 5. C. Elmore (July 18): A false chinch bug was very numerous in
two sugar beet fields near Huntington Beach. Severe leaf damage was noted
on about 10 percent of the plants. Has not been observed before in Orange
TOBACCO FLEA BEETLE (Epitrix parvula Fab.)
Tennessee. J. U. Gilmore (July 19): The first generation of flea beetles is
now emerging and is causing considerable damage to half-grown tobacco at
Clarksville. Infestations in many fields range from 15 to 20 beetles per
A TOBACCO WORM (Phlegethontius sp.)
Tennessee. J. U. Gilmore and Joe Milam (July 19): The usual overwintering
emergence of hornworm moths necessitated late June or early July dusting at
Clarksville. The lack of rainfall in July has prevented the annualheavy July
emergence, which normally produces the heavy August deposition of eggs.
At present larvae of all sizes are very scarce.
CO TT N INSECTS
BOLL ';EEVIL (Anthonor.is grandis Boh.)
North Carolina. C. H. Brannon (July 29): July has been a month of frequent
rains after the driest June in 42 years. As a result, the weevil infesta-
tion has increased rapidly in many sections. The infestation is still
spotted, somq sections having almost no infestation.
South Carolina. W. C. Nettles (July 13): The average infestation of cotton
boll weevil over the State is a fraction over 10 percent on unpoisoned cotton.
Alabama. J. M. Robinson (July 20): The boll weevil has been active in southern
and central Alabama during June and July. The first-generation adults have
been active at Auburn for a week. The infestation has advanced from 10 to
15 percent. The boll weevil is also active in the northern part, but the
percentage of infestation is not yet high enough to warrant dusting.
Mississippi. State Plant Bd. Weekly Cotton Insect Rpt. (July 29): Due to the
decrease of squares in some sections and the increase of weevils generally,
the infestation almost doubled during the past week, according to records
made by inspectors on 84 farms in 17 counties. Clay Lyle, entomologist of
the board, reports that an average infestation of 30 percent was found on
the 82 infested farms, as compared with 16 percent last week and 37 percent
on this date lest year. Showers in tle Delta were favorable for weevil
Arkansas, D. Isely (July 20): The cotton boll weevil is more abundant than
usual at this time of the year.
Oklahoma. C. F. Stiles (July 20): Boll weevil infestation is gaining slight-
ly throughout the southeastern part of the State. The average infestation of
the 17 fields examined during the week ending July 20 was 18.33 percent.
Texas. R, WV Harned (July 30): In Calhoun County damage from boll weevils is
diminishing, owing chiefly to the arsenicals that have been applied to the
cotton for leaf worm control.
COTTON LEAF WORM (Alabama argillacea Hbn.)
Mississippi. State Plant Bd. Weekly Cotton Insect Rpt. (July 22): The first
cotton leaf worm was found on July 11 in Washington County. This worm be-
came an adult moth on July 20. (July 29): Leaf worms were reported from
two faems in George County, and as they were almost grown, other infesta-
tions are expected at any time.
Arkansas D. Isely (July 18): A light and scattered infestation of the cot-
ton leaf worm was observed in Crawford County, the northwestern cotton-grow-
ing county in Arkansas. The larvae were in all stages and one pupa was also
Texas. R. W. Harned (July 30): Every acre of cotton in Calhoun County has
been successfully dusted orisprayed for leaf worm control. Many farmers
believe the infestation this year.has been heavier than in any previous year
in their experience. In other counties in this section of Texas many cot-
ton fields have been entirely stripped of foliage and the worms are eating
the squares and stems,
Texas. A. J. Chapman, L. C. Fife, and H. S. Cavitt (July): Cutworms com-
pletely destroyed 26 acres of young cotton on a farm 5 miles west of Presidio,
Larvae collected on May 23 were determined by C. Heinrich as "Feltia sp.,
possibly malefida Guen. lacking characteristic markings," Moths that emerged
on June l8 were determined by F. H. Benjamin as F. malefida. These cutworms
cut off the roots of young cotton plants just under the surface of the soil.
No leaf injury was observed. Two species of dipterous parasites reared from
this cutworm were identified by H. J. Reinhard, of the Texas Agricultural
Experiment Station, as Bonnetia comta Fallen and Gonia longipulvilli Tothill.
Egypt. A. H. Rosenfeld.(June 29): Cotton circles are at present very much
upset by an unusually early and heavy attack of the cotton worm Prodenia sp.,
but, after last year's experience, I think the second-generation eggs have
been pretty well eliminated from cotton by hand picking. The Ministry of
Agriculture inspectors are offering about 15 cents per pound for cocoons
collected from the berseem (Alexandria clover) fields, where the early genera-
tions mostly breed. The attack, as usual, is largely confined'to the Delta.
PINK BOLL WOPR (Pectinophora gossypiella Saund.)
Texas. G. G. Harris (June 30): The first worms were found in the field at
Castolon on June 17, whereas last year the first field worms were not found
until August 4. In the Presidio district the first field worm was found on
June 20. The trap-plot cotton in the Castolon and Presidio districts of the
Big Bend of Texas has been blooming profusely during June. Because of cool
weather retarding the plants in the early spring a much smaller number of
blooms has been produced this year than last; however, the number of worms
collected has been larger. During the month 121,449 blooms were produced
and 11,061 pink boll worms found, while for the same month last year 227,566
blooms and 3,503 pink boll worms were found. The infestation in the plots
increased rapidly, with the peak of infestation being reached for the week
ending June 20, after which it dropped about as rapidly as it had increased.
Bahama Islands." R. E. McDonald (June 24): V. Curtis and L. F. Curl made a
survey of the Bahama Islands from June 11' to 22 for the purpose of locating
infestations of the pink boll worm on wild or cultivated cotton. Only part
of the Islands were visited and infestations were found on only two. The
percentages of infestation of the bolls examined at various points are as
follows: Berry Island--Little Harbor Key, 19; Holmes Key, 37.68; Frazier
Hog Key, 62.35; New Providence Island--Delaport Point, 83; Wolf Road, Nassau,
66.66; Grand Bahama Island, 0; Grand Keys, 0; Great Sale Key, 0; Great Abaco,
0; Mores Island, Ot
COTTON APHID (Aphis gossypii Glov.)
North Carolina. C. H. Brannon (July): Heavy infestation on cotton reported
from Hyde County.
South Carolina. W. C. Nettles (July 18): Leaf aphid on cotton above normal
in the State.
Mississippi. C. Lyle (July 23): A complaint of severe damage by the cotton
aphid was received from Webster County on July 15 and inspector N. D. Peets
reports serious injury in many fields in Copiah and Lincoln Counties. It
is also reported in Rankin and George Counties.
Texas. R. W. Harned (July 30): The cotton aphid has increased and, with con-
tinued applications of calcium arsenate killing its enemies, may be injurious
in the near future.
COTTON FLEA HOPPER (Psallus seriatus Reut.)
South Carolina. J. G. Watts (July 18): Less abundant than last year.
Mississippi. State Plant Bd. Weekly Cotton Insect Rpt. (July 8): Some com-
plaints of flea hopper damage have been reported from Marshall, Tate, and
Washington Counties, but there is little indication of a general infesta-
Arkansas. D. Isely (July 20): Injury by the cotton flea hopper attacking
cotton has continued later than usual.
TARNISHED PLANT BUG (Lygus pratensis L.)
Arkansas. D. Isely (July 20): Injury by the tarnished plant bug attacking
cotton has continued later than usual.
GRAPE COLASPIS (Colaspis brunnea Fab.)
Mississippi. C. Lyle and assistants (July 23): The grape colaspis is
reported to be unusually abundant on cotton in the Delta. A corre-
spondent at Hattiesburg sent in specimens with the complaint that
they were damaging vegetables.
COMMON RED SPIDER (Tetranychus telarius L.)
North Carolina. C. H. Brannon (July 29): Red spiders on cotton are evi-
dent in many fields but the infestation is exceedingly light.
South Carolina. W. C. Nettles (July 1S): Red spiders on cotton more
widely prevalent than usual.
Mississippi. State Plant Bd. Weekly Cotton Insect Rpt. (July 29): Red
spiders were reported causing some damage to cotton in Washington,
Bolivar, and Sunflower Counties.
FOREST AND SHADE-TREE INSECTS
OBLONG LEAF WEEVIL (Phyllobius oblongus L.)
New York. R. E. Horsey (July 22): I was mach interested in the report
of this insect in Ohio, noted in the last number of the Insect Pest
Survey Bulletin. I was present at the discovery of this insect at
Rochester in 1923. It was a very local infestation and did little
damage, although the weevils were quite numerous on a couple of elms.
Through a careful spraying at once in 1923, apparently all the
weevils were destroyed. I have not seen or heard of one since. A
visit to these trees on July 21, 1935, shows them to be in good
health with no weevils present.
FOREST TENT CATERPILLAR (Malacosoma disstria Hbn.)
Maine. H. B. Peirson (July): Reported in Limerick, Cornish, Hiram, Bald-
win, and many other areas, especially near Lincoln and Jonesport.
Heavy infestations occur, defoliating thousands of acres of poplar and
Vermont. J. V. Schaffner, Jr. (July 24): The owners of sugar-maple or-
chards in Bennington, Windsor, end Rutland Counties are very much con-
cerned over the severe defoliation of the trees by the forest tent
caterpillar. In Windham County several natural forest areas are se-
verely infested. Collections of cocoons from four defoliated sugar-
maple orchards, where the insect apparently has reached its peak, have
given an average issuance of moths of only 9 percent and an average
parasitization to date of 37 percent. In an area not completely de-
foliated, where the infestation possibly has not reached its peak, a
collection of cocoons taken from the foliage of trees has produced a
moth issuance of 45 percent and parasitization only 5- percent.
New Hampshire. L. C. Glover (July 3): The forest tent caterpillar was
very abundant in localized areas and. apparently has increased generally
throughout the State.
Connecticut. W. E. Britton (July 23): Common in the northwestern portion
of the State, where it is feeding on.maple and other deciduous trees.
Minnesota. A. G. Ruggles and C. E. Mickel (July 23): The forest tent
caterpillar stripped leaves of poplar and birch over thousands of
acres in northeastern Minnesota. It is a menace to the tourist trade.
Also bad in Otter Tail County.
SATIN MOTH (Stilpnotia salicis L.)
Maine. H. B. Peirson (July): The satin moth was abundant on willows and
poplar in June at South Portland and H, rrison.
Massachusetts. J. V. Schaffner, Jr. (July 24): Egg deposition is reported
as heavy in some localities, especially in the region of the original
infestation at Medford and Malden.
Oregon. C. A. Cole (July 23): We have completed a satin moth survey and
find the following counties infested: Benton, Clackamas, Linn, Marion,
Multnomah, Polk, Washington, and Yamhill. With the exception of two
clumps of Silver poplars located. in the vicinity of Gervais, Marion
County, no damage is being done. Larvae were found on Silver, Carolina,
and Lombardy poplars. They seemed to prefer the Silver poplar.
CAIEZR WOP.M (Geometridae)
North Carolina. R. A. St. George and B. H. Wilford (June 9): On June 9
came across a 2-acre area of b"ack oaks not far from Asheville which
were bei'g severely defcl-ted b7y the fall canker worm (Alsb-ohila me-
taria Harr.). The eate' : Ii"ars were han.ig by threads from many of
the trees, which were i ccr'nleelt strigc.x. of foliage, and were also
abundant on the groundm ealg tihe .u a t'he trees in adjacent areas
were only liciht-ly att\..c. l.~l- n istls '.ure active on the heavily
infested area. (C. Hcinrich, ;;ic ice,-ified the rmaterial, stated that
the outbreak is a more southern one tihan heretofore known.)
Ohio. E. W. Mendenhall (July 16): The string canker worm (Paleacrita
vernata Peck) is very plentiful on apple -in western and northwestern
Utah. G, Fo Know~ton (June 7): Caterpill rs are seriously damaging the
foliage o0f -bo::-Jrl.ro, a and oa an_ at hill Creek.
Connecticiut. Wi . ritt n (July 23), Larvae of rin m'es c subius Hbn.
were fou-R fecrdir.;.i. with cannker- IeTrm in .he no:'.-: ,tn jrt oi" the
State. S:arms of the white moths were noticcd arou-d electric lights
in Bridgeport, New Haven, and Waterbury the first week of July.
LIME-TREE LOOPER (Erannis tiliaria Harr.)
New York. L. 0. Howard (July 22): Larvae were excessively abundant at
Tannersville in June, hanging suspended by their threads and getting
on everyone's clothes, just as the spring canker worms did in Ithaca
when I was a boy.
GYPSY MOTH (Porthetria dispar L.)
New England. L. H. Worthley (July ?2): According to observations by dis-
trict inspectors during the larval period of the gypsy moth, there
has been a heavy increase in infestation in the lumber-shipping dis-
tricts of western Maine, central and northern New Hampshire, and cen-
tral Massachusetts. A large amount of cut lumber piled in these sec-
tions will be exposed to the danger of becoming infested with gypsy
moth egg clusters. At present gypsy moth larvae, pupae, adult moths,
and egg clusters are to be found in the field. The first new gypsy
moth egg clusters were noticed in Providence, R. I., on July 19; in
Holyoke, Mass., on July 15; and in Chesterfield, N. H., on July 20.
New Hampshire. J. V. Schaffner, Jr. (July 24): In Hillsboro, Merrimack,
and Rocklngham Counties many woodland areas, totaling thousands of
acres, are defoliated by the gypsy moth. Severe defoliation noted as
far north as Andover in Merrimack County.
Massachusetts. J. V. Schaffner, Jr. (July 24): Extensive areas, involving
several thousand acres of woodland, consisting principally of such
favored foodplants as oak, gray birch, and poplar, were defoliated in
the northern half of Worcester County, and in the eastern parts of
Franklin and Eampshire Coiuties, east of the Connecticut River. This
is the most extensive area ever defoliated in that part of the State.
Several large areas of woodland in Barnstable Cosunt7 on Cape Cod were
defoliated. ''t the exception of a few to7ns on ';-e Cod the infesta-
tion in the eastern part of the State is very much oduced.
FALL WEBWORM (Hyphantria cunea Drury)
New York. IT. Y. State Coll. Agr. News Letter (July 1): Fall webworms are
showing up in Dutchess County.
Tennessee. G. M. Bentley (July 22): Generally bad over the State, attack-
ing various shade and fruit trees.
Mississippi. C. Lyle (July 23): The fall webworm infestation is rather
general over most of the State. The heaviest damage is occurring in the
BAGWORM (Thyrridopteryx ephemeraeformis Haw.)
Connecticut. W1 E. Britton (July 23): Street trees in one block in New
Haven infested. Some trees defoliated, others partially defoliated.
It is unusual for this insect to damage trees in Connecticut. All have
now been sprayed.
Maryland. E. iT. Cory (July 24L): Bagworms exceedingly numerous.
Virginia. H. G. Walker and L. D. Anderson (July 26): Bagworms are moder-
ately abundant around Norfolk.
South Carolina. F. Slierman (July 18): Reports indicate it to be above
average in abundance.
Ohio. T. H. Parks (July 25): Bagworm more serious than usual on arbor-
vitae. Larvae now about half grown.
Indiana. J. J. Davis (July 24): The bagworm has been quite general and
destructive to arborvitae, hard maple, boxelder, and persimmon in
many parts of the State from Lafayette south. At Lafayette the first
hatched larvae.were observed on July 12, when they were about a week
Illinois. W. P. Flint (July 24): Bagworms are much more abundant than
usual in the central Illinois area.
Alabama. J. M. Robinson (July 20): Bagworms are continuing to attract
attention in widely separated places in Alabama.
Mississippi. C. Lyle (July 23): The bagworm is undoubtedly causing the
most severe damage in many years. JTumerous complaints were received
during June and hardly a day has passed in July without receiving
BOXELDER APHID (Periohyllus negundinis Thos.)
Nebraska. M. H. Swenk (June 30): The boxelder aphid was reported infest-
ing boxelder trees in Cheyenne County on June 24.
COTTONY MAPLE SCALE (Pulvinaria vitis L.)
Indiana. J. J. Davis (July 24): Cotton maple scale was reported as very
abundant on maples at Elwood on July 20, the first report of abundance
we have had for several years.
South Dakota. H. C. Severin (July): The cottony maple scale is very
abundant on boxelder in De Smet.
CATALPA SPHINX (Ceratomia catalpae Bdv.)
Virginia. H. G. Walker and L. D. Anderson (July 26): The catalpa sphinx
is defoliating many catalpas in the Norfolk area.
Ohio. E. W. Mendenhall (July 17): Larvae are quite injurious to Catalpa
bungei and have defoliated many trees in southwestern Ohio.
Kentucky. W. A. Price (July 29): The catalpa sphinx has been very abun-
dant in all sections of the State.
ELM LEAF BEETLE (Galerucella xanthomelaena Schr.)
Massachusetts. J. V. Schaffner, Jr. (July 24): Severe browning of elm
foliage has been noted in Arlington, Belmont, Newton, Weymouth, and
Woburn. Some feeding was noted at Middleboro and North Attleboro.
Connecticut. W. E. Britton (July 23): This insect is prevalent in some
localities and scarce in others.
Maryland. 3. N. Gory (July 24): The imported elm leaf beetle has done
considerable damage in several sections of the State.
North Carolina. R. W. Leiby (July 19): Chinese elm trees, as well as
American elms, have been rather severely damaged in the eastern and
central parts of the State.
Ohio. T. i. Parks (July 25): The elm leaf beetle is rapidly defoliating
some elms in the south end of Columbus. Other complaints come from
Springfield and Lebanon. Much spraying has been done in Columbus.
7i. F. Howard (July 23): The first generation is pupating and a
few new adults are about. Injury to trees in the north side of Colum-
bus is apparent and more spraying of elms has been done than usual.
E. W. Mendenhall (July 17 and 18): The elm leaf beetle is very
injurious to elms in Cincinnati.
Idaho. R. W. Haegele (July 22): Since my report of June 19, injury to
elms has become very severe, pr-otically all elms not sprayed being
J. R. Douglass (July 13): While in Weiser yesterday I noticed
elm trees badly defoliated.
Oregon. D. C. Mote (July): After 2 years of light infestation, this
beetle is appearing in numbers and is causing damage at Corvallis.
Washington. E. J. Newcomer (July 25): This beetle has been in Yakima for
several years, and has been gradually spreading. It is causing a great
deal more damage than before and a concerted program of spraying will
evidently have to be started next season.
MOURNING-CLOAK BUTTERFLY (Hamadryas antiopa L.)
Maine. H. B. Peirson (July): The spiny elm caterpillar was feeding on
elm at South Portland on June 15.
New Hampshire. L. C. Glover (July 3): A local outbreak of the spiny elm
caterpillar has been reported in Ashland.
0BLIQUE-BANDED LEAF ROLLER (Cacoecia rosaceana Harr.)
Nebraska. M. H. Swenk (July 1 to 15): During the first week in July the
oblique-banded leaf roller was quite destructive to the foliage
and fruit of the chokecherry and also to elm leaves in Box Butte Coun-
Iowa. C. iT. Ainslie (July 31): Notwithstanding the heat and drought dur-
ing the summer of 1934, various species of aphids multiplied and became
a nuisance. Cars parked under elm trees in Sioux City were covered
with honeydew. All sorts of herbs suffered. Before the end of the
summar coccinellids multiplied and cleaned up most of the aphids. This
spring the cold wet werther gave the aphids another chance to multiply
and they appeared in devastating numbers. But it seems that the coc-
cinellids had hibernated in unusual numbers and both they and the chry-
sopas have been busy so that now it is almost impossible to find an
aphid anywhere in this region.
ELM COCKSCOMB GALL (Colopha ulmicola Fitch)
Delaware. L. A. Stearns (June 26): Injury reported and specimens received
Maryland. E. IT. Cory (July 24): Cockscomb gall has been quite abundant
Ohio. T. H. Parks (July 25): Cockscomb gall on elms has been much more
abundant this year.
Nebraska. M. H. Swenk (June 15 to 30): Reported injuring Chinese elm
trees in Scotts Bluff County on June 27.
A LACEBUG (Corythucha pallida ulmi Osborn & Drake)

the foliage browned.
EUROPEAN ELM SCALE (Gossyparia spuria Mod.)
New York. R. E. Horsey (July 22): Several elms more or less infested were
seen during the month at Rochester. The scale is apparently more num-
erous this year, although no damage to the trees was noticed.
Ohio. J. S. Houser (July 23): Numerous specimens of this insect have been
received during the past month from many sections of Ohio. The insect
is much more abundant than at any p-revious time.
T. H. Parks (July 25): More than the usual number of complaints
of damage to elms has been received. This insect was hatching at
Colunbus Curing the middle of June.
Indiana. J. J. Davis (July 24): European elm scale has been reported from
a number of localities in northern Indiana. Apparently this scale has

SCREW WORMS (Cochliomyia spp.)
General. E. C. Cushing (July 30): Reports received from southwestern
Texas indicate that screw worms are continuing to cause enormous
losses of livestock. Some ranclhmen report infestations as high as
20 percent among certain classes of range animals. Owing to recent
rains, the range feed is more abundant than it has been for several
years; however, the rains have also caused a luxuriant growth of
needle grass, one of the principal predisposing causes of screw worm
infestations in sheep. The normal population of cattle is usually
sufficient to keep the needle grass eaten down and prevent it from
causing trouble, but the recent decrease in the numbers of cattle on
the range has resulted in allowing this obnoxious grass to flourish.
The screw worm situation in the Southeast is far less serious. The
following tabulation suxmarizes the conditions in the seven States
where the Bureau is conducting control operations:

Texas. D. C. Parman and A. W. Lindquist (July 11): Screw worms, C. ameri-
cana Cushing and Patton, are causing very serious losses to livestock
owners in southwestern Texas, the outbreak being associated apparently
with the unusually heavy precipitation during May and the early tart of
June. Some of the le-ding ranchmen in the vicinity of Uvalde state
that theo believe losses will be he.vier in that section this year from
screw worms than the losses from lack of feed during.the droughts of
1933 end 1934.

Winterhaven. As man.r as 5,000 of the gnats were found on a mule at one
time, being: concentrated mainly, along the belly and around the ears.
The gnats also attack other: classes of animals, including milk cows,
and it was found necess.:rr to cover the udders. The outbreak was prob-
abli; accentupted by the flood in this area.
SHEEP BOTFLY (Oestris ovis L.)
Utah. G. F. Knowlton (July 3): Heai maggots were coimon at Woodruff dur-
ing the past winter and spring. Reports indicate that they are common
in sheep in other Darts of Utah.

California. H. C. Donohoe (July 1): Small numbers of adults were taken in
malt-sirun bait traps in a variety of orchard locations in vicinities
of Winters, Vacaville, Yuba City, and Orland during the last 2 weeks
in June. This storage pest appears to be well established and widely
distributed in the field in California, as it is also frequently taken
in trap catches in the San Joaquin Valley.
BLOW FLIES (Lucilia spp.)
California. H. C. Donohoe (July 1): L. sericata Meig., and L. sylviarum
Meig., especially the former, are abundlnt in drying yards. They swarm
