The pthramount feature of the month is the devastating grasshopper outbreak in the Great Plains which is said to be the most serious of any since the early settlers were demoralized by the invasion of the Rocky Mountain locust in the decade between 1868 and 1880. Serious grasshopper outbreaks were quite generally reported from New York westward to Idaho, Nevada, and Arizona, and southward
to Arkansas, Oklahoma, and Texas.

The severe outbreak of the variegated cutworm which was reported during
June in the 'est-Central States was followed in July by a similar outbreak of this same insect in the North-Central States.

Late sweet corn on over one thousand acres of land in San Diego and Los
Angeles Counties, Calf., Was practically ruined by an undetermined climbing cutworm.

The fall armyworm appeared in destructive numbers in the Everglades of Florida and in the Mississippi delta of Louisiana during July. This is two months
later than it appeared in destructive numbers in the Gulf Region last year.

The painted lady butterfly was quite generally reported from New England
to the Dakotas, the larvae feeding on hollyhock and burdock.

The chinch bug seriously damaged corn in 'southern Illinois, central M!issouri, and southern and central Kansas. It also did some damage to this crop in northern Ohio. This insect seems to be building up an abnormal population north of the normal chinch-bug belt in South Dakota and Iowa.

The corn ear worm was more numerous during July in the North-Central States than it has been for several years and in Nebraska is doing more damage during this July than any July in the past 30 years.

An interesting account of the variegated fritillary (Eurtoieta claudia
Cram.) doing commercial damage to beans, sweetpotatoes,and melons in Tennessee was reported in late June.

Correction: Outstanding Features, July 1 Bulletin, page 242, last paragraph under Mexican ruit worm. Damage referred to was in April instead of Jtue as might be inferred. See same number of the Bulletin page 315.



The establishment of a considerable colony of Bruchus brachialis Fahraeus attacking vetch in the field near Haddon Heights, N. J.,and infested material from Delaware and Maryland was discovered during the month.

The peak of 1st-brood codling moth emergence in the Hudson River Valley occurred about July 7. The second-brood moths started to emerge in central Ohio about July 9, but up to July 20 no emergence had been observed in the fruit belt along Lake Erie. Severe infestations were reported quite.generally in the eastern part of the United States. Band counts in western Illinois indicate that the population is 10 times as great as at the same time last year, and in eastern Illinois about 25 times as great.
Considerable damage is being done by the grape leafhopper from New Jersey
westward to Ohio.

Blister beetles as usual are now attracting a great deal of attention on a variety of crops in the East-,t'ntral and West-Central States, Say's blister beetle becoming quite numerous in New England ind in New York.

The false chinch bugs are very numerous over a large area in Iowa and Nebraska. They are also numerous in parts of Texas, Colorado and South Carolina.

Colorado potato beetlestcrc discovered on a city lot in Ogden', Utah, during late June. By the end of July it appeared that this infestation had been eliminated.

Thegotato leafhopper with the associated hopnerburn is prevalent in the EastCentral States, southward to Kentucky and westward to Iowa and Minnesota.

Larvae of the Mexican bean beetle were collected during the month in Washington County, PRhode Island. Considerable damage was done by the first generation of this insect inConnecticut. It-was reported for .the first time from Esopus and Port Even, New York. Inthe older infested region in the southern Middle Atlantic States but comparatively little damage is being done by this insect.

The squash bug is being reported much more frequently than last year from the Middle Atlantic States, southward to Georgia, Alabama,and Mississipii. It was also reported as doing serious damage in Iowa and Utih. In Idaho, where it was first discovered in 1929, it is now quite generally destructive over'the southwestern part of the State.

A serious outbreak of'the beet webworm is occurring in parts of Wyoming..
The insect is also unusually abundant in Montana, and North Dakota. In W7yoming the insect seriously damaged beans into which they migrated from near-by fields.

The elmn leaf beetle, reported as occurring in southern New England in the last number of the Insect Pest Survey Bulletin, was reported during July from New Hampshire southward along the Atlantic Coast to Maryland with occasional outbreaks in Ohio and Kentucky.


The spruce budworm is defoliating, large areas of balsa-i fir and several species of pine in Tisconsin and parts of North Dakctrt. This insect was discovered for the first tihQ in Cody Canyon, tyo., in 1926, and since that time it has spread over a tremendous acreage and has destroyed large areas of Douglas fir.

About 43,000 acres of poplar has been defoliated in Maine by the 1;plar leaf roller, Cacoecia conflictana ialk.

EYe gnats have been very annoying along the South Atlantic aboardd from Maryland to Georgia and'around the Gulf to Mississippi.


The severe outbreak of the pale western cutworm in Saskatchewan and eastern Alberta drew to a close late in June. In addition to this species, the
red-backed cutworm occurred in injurious numbers over a wide area in Saskatchewan, particularly in par ::sections. It was widespread in Manitoba, notably in central and northern areas, and reports of its -prevalence in Alberta were also received. Cutworm injury has been severe in many arts of British Columbia and damage by cutworms also has been re-ported from various sections of eastern Canada, although, except in southwestern Ontario, their attacks apparently were not particularly severe.

Moths of the army cutwo-rm have been unsually abundant in the three Prairie
Provinces, where they proved an annoying pest in and about houses.

In British Columbia, the Nicola and Okanagan valleys are largely free
from grasshopper trouble, but a severe outbreak of the lesser migra.tory :;rasshopper in a section of the Fraser valley resulted in considerable loss to clover grown for seed. Damage due to grasshoppers, chiefly the clear-winged and lesser migratory grasshoppers, in Saskatchewan is widespread, -articularly in south-central sections. Prevalent but localised outbreaks of the former species are occurring over a wide territory in Manitoba, notably in the southecstern part of the province. Grasshoppers continue on the upward trend in sections of Ontario and southern Quebec.

Important crop damage by wireworns of several species is occurring over a large area of Sas katchewan, and in east-central Alberta and southwestern Ontario.

Further retorts from southern Quebec, southern Ontario, and souther M. anitoba indicate that the Colorado potato beetle is definitely more abundant than usual in the above territories.

Heavy infestations of potato flea beetles are noted in the St. John River valley, New Brunswick, in southern quebec,and in Ontario. Flea beetles are proving injurious to cruciferous crops in the Okanagan valley, British Columbia, and to sugar beets in Alberta.

The striped cucumber beetle is unusually numerous and destructive in the Annapolis valley, Nova Scotia, the St. John valley, New Brunswick, and in sections of southern Quebec and Ontario.

The cabbage maggot appears to be in outbreak form throughout southwestern Ontario and has done much damage to cruciferous crops. It is on the increase in the Lethbridge district, Alberta.

Evidence of a marked reduction in the European red mite infestation in the orchards of the Annapolis valley, Nova Scotia, is reported.

Throughout Manitoba, Saskatchewan, and Alberta the spideimite Paratetranychus uniunguis Jac. is attacking planted spruce and, in the Riding and Duck
Mountains, is seriously infesting native white .spruice. The*pest is increasing in importance each year, its development being particularly favored by the provailing dry weather.

A moderate outbreak of the spruce budTrorm has been noted in the Porcupine district, Ontario, and an extensive outbreo. of the eastern spr-ce bark beetle has been reported on the north shore of the St. Lawrence River, Quebec, in the Manicouagan River. region.

The aphid species Dreyfusia piceae Ratz. is infesting much of the balsam in the southern part of New Brunswick., especially near the Atlantic coast, between St. John and St. Stephen.



Ohio T.H. Parks (July 21): Melanoplus atlaniuL Riley, M. femurrubrum DoG. and M. bidittatus Say are moderately to :ory abundant
than usual in most parts of Ohio. (July 27): Grasshoppers are
now quito common and calling for control measures in many places.
County agents are prepared for poisoning campaigns and work is
already started in a few western counties.

Illinois J. H. Bigger (July 20): Grasshoppers are attacking corn. They
have destroyed 10 acres of soybeans in one field in Adams County.

Kentucky W. A. Price (July 23): Grasshoppers are very abundant on corn,
tobacco, alfalfa, blue grass, and vegetables in central Kentucky.
Just now tobacco is receiving the greatest amount of injury.

Wisconsin C. L. Fluke (June 30): Grasshoppers, Camnula pellucida Scudd.,
moderately abundant in Door County.

Minnesota A. G. Ruggles and assistants (July): Several hundred thousand
acres of crops. have been destroyed in Kittson and Marshall Counties. The specie.s involved is principally Melanoplus bivittatus
Say, with Camnula pellucida Scudd. becoming more predominant
farther north in the State. M., mexicanus Sauss. and M. femurrubrum DeG. are also quite prevalent. Dissosteira carolina L.
is quite prevalent in Norman County. (Abstract, J.A.H.)

North Dakota J. A. Munro and assistants (July 17): A survey of Pembina
County made lately showed that many fields of flax and small
grain crops had been ruined by grasshoppers. Farmers, not only
in this county but in many others, are actively engaged in
applying poison bait to save their crops. -Serious depredations
also reported from Walsh, Golden Valley, Mountrail, La Moure,
Kidder, Burke, and Ward Counties.

South Dakota H. C. Severin (June 29): Grasshoppers are very abundnt. This
State is experiencing its worst grasshopper outbreak in its history this year. The worst infested areas include Brule, Buffalo, Charles Mix, Gregory, Mellette, Jones, and Lyman Counties. Considerable damage is also being done in Stanley, Hughes, Sully,
Dewey, Marshall, Codington, Clay, Bon Hommne, Butte, Pennington,
Brookings, and Clay Counties. The predominant species is
Melanoplus bivittatus Say with a sprinkling of M. mexicanus Sauss.,
M. femur-rubrum DeG., ahd other species.

Iowa H. E. Jaques (July 24): Grasshoppers are very abundant in
many localities throughout the entire State. The worst outbreak
since 1918.

Missouri F. M. Wadley (July 10): Grasshoppers are quite generally
abundant, and in some spots injurious. Inuty to alfalfa is
most marked, but some damage to corn and soybeans is noted.

Nebraska M. H. Swenk (June 15*- 30): The severe outbreak of grasshoppe:
chiefly of the two-striped grasshopper (Melanoplus bivittatus Sa; which by the middle of June included Knox, Boyd, eastern Keya Pa and the northern parts of Holt and Rock Counties, developed duri
the last, half of June to include not only all of Holt and Rock
Counties, but thence south to the Platte River, in Hall, Buffalo and Dawson Counties, west through Custer County and east to include Cedar County, thus including altogether all or most of
sixteen Nebraska counties. Over this area there has been much
damage in the alfalfa and. small grain fields, and serious damage to corn is now starting as the small grains ripen and the grasshoppers get their wings. The other grasshopper-infested areas
in the State have about the same status as was described in my
previous report.

Kansas H. R. Bryson (July 23): Grasshoppers are very abundant in
several localities and in northwestern counties. Most destruction
in western one-third of State. Grasshopper injury is on the
increase in the State. Kansas weekly crop report for July 20
stated that grasshoppers have injured alfalfa in both western
*and eastern Kansas. If dry weather continues to retard crop
growth injury from this pest will become more apparent.

Arkansas Dwight Isely (July 23): The yellow grasshopper has been unusually abundant, outbreaks causing serious local damage in
northwestern Arkansas and in bottomlands' along the White and
Arkansas Rivers.

Oklahoma C. E. Sanborn and assistants (July 22): Grasshoppers are very
abundant. Local outbreaks in numerous sections of central and
southwest part of State.

Alabama J. M. Robinson (July 23): Grasshoppers are moderately to very
abundant in aat of Lee Coity, in cotton'fields.

Texas Topeka Daily Capital (June 15):'Hordes of grasshoppers invaded
the business section of El Paso last night and in some places
piled up more than a foot deep. Police scooped up box loads and
gave them to fishles ih public pakks.

Montana R. W. Gjullin (June 30): Melanoplus bivittatus Say and M.
femur-rubrum DeG, are modefdtely abundant in the central valley
and in the eastern part of State.

Wyoming A. G. Stephens (July 20): Grasshoppers are very abundant in
the northeastern and eastern section of the State.

C. L. Corkins (July 20): The only new development in the grasshopper situation in Wyoming is the extension of the outbreak into the lower North Platte River Valley, particularly
Goshen County.

Colorado C. P. Gillette (July 22): Grasshoppers are very abundant
generally in the eastern Colorado plains. To date the Experiment
Station has put out poison enough to treat 200,000 acres with
arsenic-bran mash.

Id-aho C. Wokeland (July 23): Grasshoppers, numerous species, are
very destructive to farmers in some of the higher mountain valleys in northern Idaho, where control is difficult because of the large
proportions of range land adjacent. Grasshoppers are causing
serious injury to irrigated crops in many sections of southern
and southeastern Idaho and considerable work is being done by
individuals and small-scale organizations in control.

Nevada G. G. Schwels (July 20): Grasshoppers are very abundant. Doing
much damage to alfalfa and grain in Washoe County.

Utah G. F. Knowlton (July 10): Grasshoppers are extremely abundant
and. causing serious damage to wheat, alfalfa, oats, barley, and
many other crops in Utah. The.lesser migratory locust (M. atlantis Riley) is usually the most abundant species encountered.
The two striped locust (M. bivittatus Say), Packardts locust
(M, packardi Scudd.), and several other species are encountered
in damaging numbers in certain localities. This is the most
serious grasshopper outbreak that has occurred so generally over
Utah for a number of years.

Arizona C. D. Lebert (July 28): Several species of grasshoppers,with
M. differentialis Thos. and Trimerotropes sp. predominant, are
still doing serious damage, Farmers are continuing use of hopper
dozers and poison bran mash.

Oregon D. C. Mote (July 13): C. A. Henderson, Klamath Falls, reports
that so far grasshoppers have been kept in check, and tremendous
kills were made in the Fort Klamath, Upper Klamath, marsh at
head of the Willipnson River, Sprague River, Sycan, and Upper
and Lower Chewaucan. It is believed that 95 per cent of the
early hatches were killed by the use of poisoned bran mash.

FIELD CRICKET (Gryllus assimilis Fab.)

North Dokota J. A. Munro (July 18): The black field cricket is ypering
in greater abundance in a number of counties than for the past
few years. It is repotted from McKenzie, Golden Valley, ;illiams,
Burke, Grand Forks, Cass, and Traill Counties, both as a pest in
houses andi to field crops.

California S. Lockwood (July 6): During the month of June reports came
to this office indicating that the black field cricket (Gryllus


assimilis Fab.)y~ja$ responsible-for considerable &dn-e to peaches
in the. northern part of Sacrazvento-Cointy.' Later reports seem to. indicate tiatl- the* &ma-e f done-by this insect at all, was

I ~CUTWORM'S (*octiuidae)

Tennessee. C. M.. Packcard ( 6):* Tho varieLted cutworm (Lyc oT ho tia
margaritosa sa.i Him. ) is pres'tin small numbers in every
armywo rm horde 'o'b ierve d It seens'to have been the species
responsible 'for dai1'.age to clove+ 'fields* attributed to the armworm. It is present by. the. million, in a 30-acre field of crimson clover nhear Belvi'de're, --observed June 5. It caused some injury by
eating leaves and stems. The 1ieads were toom.early nature for *uch injury. Migration into cbtn across a 1afte *a~s sopped by
turning hogs into. thelane.' P~5ae wore. common Junie 16. The first adult in c-ages, ap'oearpd June* 18.. About 90 per cent of
the wio rms were pnrasiti~ed by' tachiids.

Wisconsin E. L. Chambers (July 22): An unusual outbreak of cutworms has
occurred throughout the State this summer, and at the present
time the variegated cutworms (Lycophotia margaritosa saucia Hbn.)
are doing the most damage. In several localities, including
Douglas, Bayfield, Barron, Kenosha, Milwaukee, Racine, Ozaukee,
and Washington, the armyworms (Cirphis unipuncta Haw.) were
associated with the variegated cutworms and did serious injury
for several days until brouglhunder control by parasites,
Apparently the variegated cutworms were much slower to be parasitized. More than 600 farms in Ozaukee County were infested and
many fields of sweet clover and alfalfa completely defoliated
and much injury done to corn and potatoes before the poisoned bran could be spread. Large quantities of poisoned bran wer3
prepared at the county seats and distributed at cost to farmers
in Ozaukee and Washington Counties.

Minnesota A. G. Ruggles and assistants (July): The serious cutworm
situation of the spring has now a'oated and the only report of
importance is one on the variegated cutworm (Lycophotia
margaritosa saucia Hbn.) as being abundant on tobacco in Benton
County. (Abstract, J.A.H.)

North Dakota J.A. Munro (July 3): Just yesterday I had the first report of
the Bertha armyworm (Barathra configurata Walk.) for the season.
It is already destroying fields of flax in the western part of
Grand Forks County. (July 18): Two reports of Bartha armyworm
injury to flax are reported from Benson and Grand Forks Counties,

Montana R. W. Gjullin (June 30): The pale western cutworm (Porosagrotis
orthogonia Morr.) is moderately abundant in the northern, central,
and eastern parts of the State. (June 30): Army cutworms,
Chorizagrotis auxiliaris Grote, are very abundant in the central
part of the State. (June 30): Adults of the army' cutworm arc.
very abundant in the north central and central parts of the State.

Oregon L. P. Rockwood (July 3): Spots comprising in all about onefourth acre in a 200-acre field were damaged June 5, 3 weeks
after the maximum flight of moths. Spots failed to increase in
size although cutworms,Agrotis ypsilon Rott., avera6ed 7 per
square yard in these places. Probably birds cleaned up the small
bands of cutworms.

California S. Loclkwvood (July): An unidentified R.octuid larva has been
responsible for very severe damage to field and sweet corn on about 1,000 acres in the Mission and Tia Juana valleys of San
Diego County. Reports indicate that this same condition exists
in parts of Los Angeles County. The later sweet corn will be
entirely ruined and the tonnage of the field corn will be
ut*:s~verly,:This pest destroys the tassels when they are still in the boot
and seems to like the;silks, ears,and forming cobs of the youner


ears and bores into the stalk of the corn plant. It is not
uncommon to find as *high as four or five worms to one corn plant.. Our attention was called to this by Mr. R. R. McLean,
County Agriculture Commissioner of Sani Diego County.

AIf W ORM (Cirphis unipuncta Haw.)

Virginia .H. G. Walker (July 24): Although the first generation of the
armyworm did considerable damage in the Norfolk section, the second-generation larvae have not been observed in the field.
This would seem to indicate that the parasites and predators
of the armyworm had greatly reduced their numbers. The second
generation of larvae reared in the insectary are now nearly
full grown.

Ohio T. H. Parks (July 21): The armyworm outbreak extended between
June 20 and July 3. A high percentage of the larvae were parasitized but the moths emerged during the middle of July and were attracted to lights. Good results were secured from the application of poisoned bran mash bait and not much corn was destroyed on farms where this Was used. The greatest area of infestation covered parts of six counties in the south central part of
the State, Outlying reports came from some couftties in southwestern Ohio.

Indiana C. M. Packard (July 6): Outbreaks of the armyworm were reporte
from a number of places in the southern half of Indiana in early
June. Excellent results were obtained with poisoned bran mash
spread broadcast. The worms developed in timothy, barley, wheat,
and rye fields, principally in the lower or richer spots which
apparently had been most attractive to the- ovipositing moths
early in the spring. The crops were seriously injured or entirel
ruined in a number of such areas. Migration to adjcent young
corn and resulting injury to it was also observed.

Adult moths reared from both Indiana and Kentucky material
proved to be the true armyworm (Cirphis unipuncta Haw.). Several tachinid and two hymenopterous parasites were reared. Parasitis
was Very heavy in Indiana and it seems doubtful if the next
generation of worms will be seriously abundant. Parasites were
also very abundant at Shelbyville, Ky., but seemingly not so much
so as in Indiana. Many apparently healthy pupae are in the groun at Shelbyville and a sizeable second generation of worms this yea
is possible.

J. J..Davis (July 25): The armyworm appeared in destructive
numbers in isolated points throughout the State. Definite report
were received as follows: Damaging rye, corn, timothy, etc.,at
Madison, Aurora, Logansport, Leroy, and in eight townships in
Rush County where wheat was the principal crop damaged.

Kentucky C. M. PC.Ckard (July 6): An outbreak near Shelbyville, Ky.,
visited June 17 and 23. More extended injury to barley seen in
this area. The worms had finished feeding in some of the fields.,


hence it was too late to apply control measures. Corn adjacent
to barley was being destroyed.

Michigan R. H. Pettit (July 1): -Yesterday there appeared the first
armyworm outbreak for Michigcan for this year. It occurred at the Game Farm ncar Mason and about 20 acres of wheat were involved. (July 10): Armyorms have appeared in Presque Isle, Mason, Grand Traverse, and Ingham Counties. Thc attacks have
not boon so severe as at some times in the past, but considerable
d.m age has been done.

Missouri Daily Drovers Telegram (June 23): Severe and widespread outbreaks of armyworms have been discovered in southeastern Missouri,
particularly in Scott County, according to Plant Com-:issioner
K. C. Sullivan of the Missouri State Board of Agriculture.

Tennessee C. M. Packard (July 6): In southern Tennessee some &-mage
from the armyworm continued into first week in June. First pupae
were observed in the field June 1 and prctic- g_ .had
pupated by June 12. The first adult in ?> .cz~ une 4. H. G.
Cress, County Agent of Marshall County, put on a county-wide
control campaign with poisoned brac. broadcast over entire fields
where infestation was present. This effort was so successful that the only loss in the county was to spring-planted clover and tinrothy in grain fields. In other counties where no such
control effort was made there was much damage to oats, rye, barley, wheat, and corn. High parasitisn by tachinids was
observed in all localities. (C. Benton)

1 FALL APIWOR1,I (LaphLya frubinerda S.& A.)
Florida J. R. Watson (July 24): The most striking and newest developrent of the past month has been an outbreak of the fall armyworm.
The outbreak has been very severe in the everglades (R. N. Lobdell),
and locally severe as far north as Pinellas and Polk Counties.
In the latter counties it has been mostly confined to crab grass.
The worms are just appearing about Gainesville.

Louisiana W. E. Hinds (July 25): The grass worm is now maturing in at
least the second generation and corplaint of light infestation
on several hundred acres of sugarcane was received from West
Baton Rouge Parish on July 17. Extninations showed that -ost of the larvae had entered the ground for pupation. Those remaining were full-grovwn and a very large percentage was parasitized. We do not anticipate serious injury from the next

PAINTED LADY (Vanessa cardui L.)

New ngland J. V. Schaffner,Jr. (July 21): Larvae of this species appeared on bollyhock in Massachusetts about the third week in June


and since then many collections were taken on hollyhock and
burdock in several Massachusetts, New Hampshire, Vermont, and
Maine localities, as far north as Rutland, Vt., and Bangor, Me.
This species has not been reported to us since 1926.

mine H. B. Peirson (July 22): The painted lady was very abundant
in Augusta on hollyhocks, July 20.

Ohio E. W. Mendenhall (July 21): I find the painted ladyv infesting
thistles in southwestern Ohio. It fastens leaves together and is now in the pupa stage. (July 21): There is some abundance
of this insect. I find the painted lady on hollyhock in the
pupal stage in a garden in Springfield.

Illinois W. P. Flint (July 21): The painted lady butterfly larvae are
reported very abundant in northern Illinois on Canada thistles and hollyhocks. Larvae have also been taken by members of our sta~f in soybean fields, especially in the eastern part of the

Minnesota A. G. Ruggles (July 21): Very abundant all over the State
and in many places damaging sunflowers and the hollyhocks.
Also reported on lettuce and rape. Great glee for the most
part because of the attack on thistle.

North Dakota J. A. Mturo (July 18): The painted lady or thistle butterfly
is abnormally abundant over a large section of the State, particularly the eastern llf. The caterpillars have been feeding
largely on the Canada thistle and to a lesser extent on hollyhocks and a few other plants.

South Dakota H. C. Severin (July 14 i ffterpillars of the painted lady
reported general. Canada/chially is attacked though hollyhocks
suffer considerably.

Nebraska M. H. Swenk (July 1 15): During the early part of July a
number of correspondents reported that the Canada thistles had been rather severely eaten by the larvae of the thistle butterfly.

WIREWORMS (Elateridae)
Maryland E. N. Cory (July 9): Wireworms, .A:riotc manrus Say, were
received from J. H. Carter, County Agent, Oakland, Garrett County, who says that the worms appeared about ten days ago
in a farmers cornfield and have destroyed about one-half acre.

North Dalkota J. A. Munro (July 18): Wireworms were reported as abundant
in Golden Valley County in corn which followed flax and in
fields of corn and potatoes in McKenzie County, but scarce in
Williams County, moderately abundant in Pembina County, and
scarce in Morton County.


Nebraska M.H. Swenk (July 1 15): A Saunders County correspondent
reported a potato field that had been planted in an old orchard,
among the tree stumps, to have the tubers badly eaten by the
wireworm Melanotus communis Gyll (July 1): Wireworms, M.
pilosus Blatch.,were very injurious in a corn field in Dodge
County during the last week in June, about 30 acres being involved in the injury.

Idaho C. Wakeland (June 30): The.usual reports of wireworms
damaging spring crops are being received by out office, evpecially from the irrigated districts of southwestern Idaho. The
range of the insect seems to be extending in the Twin Fa.lls
area since we are receiving more reports from there this
season. Damage in general is not being so severe as during
other years but injury is reported on potatoes in several new

SAND WIREWORM (Horistonotus uhleri Horn)

South Carolina J. N. Tenhet (July 3): In the experimental plots at this
station a half acre of late potatoes was very severely injured
by the J=ndy-land wireworm. The yield of marketable potatoes
was cut at least 75 per cent. (July 16): Adults are becoming very scarce, and larval attack seems to be slackening. Larval
injury has been very severe this spring.

WHITE GRUBS (Phyllophag spp.)

Georgia 0. I. Snapp (June 30): May beetles have completely defoliated
some young European elm trees which were planted for shade in the
city of Fort Valley. The beetles worked at night, and the
owners were attributing the trouble to some disease, since no
insects were observed on the trees during the day.

Wisconsin C. L. Fluke (June 30): White grabs are very abundant in
southern Wisconsin only. Hatching from June 20 to date.

North Dakota J. A. Munro (July 18): White grubs caused light injury to
garden crops in Hettinger County and were moderately abund-ant
in parts of Walsh County.




FESSIAN FLY (Phytophaa destructor Say)

Ohio T. H. Parks (July): The Hessian fly has about doubled in
population as determined through the annual wheat insect survey.
No serious injury occurredjtothe present crop, which promises
to be the largest in many years. The heaviest fly infestation
is in the northeastern counties though it is now present in
threatening numbers in nearly all sections of the State.

WHEAT STM LAGGOT (Meromyza americana Fitch)

Minnesota A, G. Ruggles and assistants (July): More abundant than
usual. As high as 10 per cent loss being credited to this
insect in many wheat fields. (Abstract, J.A.H.)

North Dakota J. A. Munro (July 18): The wheat stem maggot has been
noticeably present in the eastern counties of the State. Many
fields in Traill Countyr were reported to have suffered a loss
of 10 to 12 per cent from this pest. A survey of fields in
the Fargo vicinity shows a 2 to 3 per cent loss. In Richland
County it is reported as causing a general loss of 0.5 to 1
per cenrt.

Nebraska M. H. Swenk (July 1): During the third week in June a few
reports of an abundance of the wheat stem maggot were received
from east central Nebraska, from Dodge County to Greeley County,
but the damage was not widespread or very serious.

Tennessee S. Marcovitch (July 2): Several new outbreaks of this insect
reported from Lewisburg as doing serious damage to corn, tobaccc
and grasses.

ANT ARCTIID MOTH (Apartesis piiyllira Drury)*

Tennessee C. M. Packard (July 6): Adults reared from larvae sent in by
Mr. Benton from the April outbreak of this species in southern Tennessee were determined by Mr. Wm. Schaus as above, The last adult was seen in the field June 5. Field observations yieldd
no trace of second-brood larvae until a small infestation was seen on June 23 in a hillside pasture near Fayetteville, Tenn.
On June 24 a considerable infestation of practically mature
larvae was seen in a hillside pasture 8 miles northwest of
Petersburg, Tenn. H. G. Cress, Marshall County Agent (Tenn.) reported (June 30) several outbreaks with damage to pastures up to 20 per cent and threatening injury to corn and tobacco.
(C. Benton.)

CIiCE BUG (Blissus leucopterus Say)

Ohio T. H. Parks (July 27): Chinch bugs have been reported damagii
corn in several northern Ohio counties. There is no serious general outbreak in any part of the State, but the insect has
increased rapidly during the past year. Excellent growing
weather enabled corn to outgrow their attack.

Indiana J. J. Davis (July 25): Chinch bugs were reported as moderately
abundant in cornfields in Whitley County about the middle of Jul

Illinois W. P. Flint (July 20): Chinch bugs have been favored during
the past month by dry weather over most of the heavily infested
area. Serious dftmnage to corn ihas resulted in a number of the
south central and central counties with some scattered outbreaks outside of the generally infested area, the most northern of the
being in Hancock County on the west side of the State.

South Dakota H. C. Severin (July 14): Chinch bugs are again building up
their population in 1outh central South Dakota. There has been
little damage as yet. (Charles Mix and Tripp Counties.)

Iowa H. E. Jaques (July 24): Two serious infestations of chinch bu
are reported from Dos Moines County.

Nebraska M. H. Swernk (July 1 15): Dozens of farmers in eastern
Nebraska have inquired concerning the abundance of corn ear
worms working on their corn, boring t-hrough the bud and downward
in the stalk, and devouring the upper leaves and the tassels.
The first reports of damage of this sort came from the counties
bordering the Missouri River, from Cedar, Dixon, and Thurston Counties south to Otoe, Nema:a, and Richardson Counties. This
damage began to be apparent along the Missouri River during the last few days in June. By the middle of July it was showing up
in counties farther west, as far as Madison, Platte, and LancastE Counties. In many fields this injury has been serious. Not for at least the past 30 years have caterpillars of this first brood
been so numerous as they have this year. This great abundance of corn ear worms of the first brood indicates the probability of unusually heavy damage to the milky and maturing kernels of
the corn during August and September by the second and third
broods of ear worms.

Kansas P. M1. Gilmer (July 14),-,. The corn ear worm (determined by
Heinrich) has been observed causing injury to apples in an
orchard near Belle Plaine, Much of the fruit was completely
hollowed out, leaving merely a shell attached to the tree. The injury was confined to trees with branches drooping until they
made contact with the soil, although fruit as high as 6 or 8
feet above ground was attacked. The original infestation was apparently in a heavy planting of winter vetch which was used as a cover crop in the orchard. This had not been cut at the
time the larvae were taken, but a good many fruits even at some
distance from the ground hamd been attacked.

H. R. Bryson (July 23): Damage from the corn ear worm has been
quite noticeable in different parts of the State. Complaints
have been received from as far west as Nashville and Great Bend.
The first complaint sent in was from Ottawa, July 3.

Oklahoma C. E. Sanborn and assistants (July 22): The corn ear worm is
very abundant.

Alib&aa K. L. Cockerham (July 9): During the month of June early fresh
corn was heavily infested with the corn ear worm. Inspectors for the Bureau of Markets estimated that at least 90 per cent of the
corn moving after the middle of the month was infested. A lot
of this injury did not throw the corn out of grade because it
was confined to the first inch and a half of the silk end of the
ear, which is allowed by the Bureau of Markets. There were some
cases, however, where daz-.-ie increased while the corn was in

APLE(i~&PI AP ~ -)(Lz-, D G.)

Connecticut P. Garman (July 23): Green apple aphids appeared in many orchards
the latter part of June, but have decreased in numbers since the
middle of July.

New York N. Y. State Coll. of Agr., Weekly News Letter (July): During the
month te apple aphid developed into a serious problem in some
orchards in the Hudson River Valley. Towards the end of the month
the situation had become very serious. In the w-estern part of the State a very similar situation prevailed, in some cases necessitating the use of nicotine. (Abstract, J. A. H.).

New Jersey N.'J. State, C91l. of Agr., Weekly News Letter (July): There are
still a large number of green aphids on trees at the present time
in orris County.
Pennsylvania H. N. Worthley (July 22): Green appl6 aphids are moderately
abundant at State College.

WOOLLY APPLE APHID (Eriosoma lanigerum Hausm.)

Washington M. A. Yothers (July 17): This aphid got an early start in March,
April, and May but by mid-June it had been pretty well cleaned up
by predators. During the past two or three weeks it has increased
in tremendous' numbers until it is'now more abundant than usual at
this time of year, in Wenatchee.

CODLING MOTH (Carpocapsa poironella L.)

New Hamnshife L. C. Glover (July 22): The codling moth is moderately abundant.
It is plentiful in certain orchards.

New York N. Y. State Coll. of Agr., Weekly News Letter (July): The earlie:I
codling moth larva to be observed in the extreme northeastern corn
of the State in Clinton County was seen on June 20. During the
middle of July codling moth injury was much more serious than at
the same time last year. Poorly spray-ed orchards are running from
20 to 60 per cent infestation In the Hudson River Valley.., The
bait pails indicate that the peak of moth emergence appeared about: July 7. The first mature codling Toth larva was found under bands
on July 4. In the western part of the State emergence was at its
peak about July 1. During the middle of July the amount of injury
increased very materially.

New Jersey N.J. State Coll, of Agr.. Weekly News Letter (July): Second-broo
side worms are now active in southern Now Jersey. Counts made of
first-brood injury indicate that the damage in most orchards is
greater than last year.

Pennsylvania H. N. Worthley (July 9): Mature larvae started cocooning June 27.
A fer spring-generation adults are still bout.. The spring gonration is very abundant at Biglerville, Adams Cbunty, as many as
22 stings per apple in cll-sprayed Yorks. (July 22):Surer-brood
moths are now emerging.

T. L. Guyton (July 27): The codling moth is very abundant in Franklin County.

Delaware L. A. Stearns (July 22): Second-brrod egos of the codling moth
are now hatching; infestation is severe in some orchards; there
supplementary control, measures e-e practised and thorough spraying -as accomplished injury is but moderate.

Maryland E. N. Cory and assistants (July): The first adults emerged at
Hancock July 7.

Georgia C. H. Alden (July 20): The codling moth is very abundant at
Cornelia. There are many stung and -orrnj fruits in co-Tercial
orchards. Second-brood moths are now laying eggs. Infestation
is heavier than in 1930. The hot, dry wether of this year is
ideal for multiplication.

Ohio T. H. Parks (July 21): This insect is ruch moe abundant than
usual in the orchards "here it has been a problem. Second-brood moths commenced emerging in Lawrence County June 29, at Columbus
July 9, and at Wooster July 13. No moths of the second brood have
yet emerged along Lake Erie. More thorough straying is in progress
than for many years- and in some orchards the amount of "orry fruit
present in Juno indicated that the losses from the second brood
would be heavy. The -oroblem is most serious in the southern third
of the State and in Ottawa County in north-estern Ohio.

Ellinois W. P. Flint (July 20): Infestations are ionorally heavy in
south central, central, and western Illinois 7ith scattered orchards
showing very heavy infestation in the southern part of the State.
Collections under bands in western Illinois have yielded about ten
times the number of larvae taken from the semo number of trees in
the same orchard on the corresponding datasof 1930. In eastern
Illinois approximately 25 times as many larvae have been taken under
bands during the last three weeks as were taken last year.

ntucky C. 0. Eddy (July 10-15): PAl-trap catches of the codling moth
were very high during the period of July 10 to 15 at Henderson and

from scarce to moderately abundant throughout practically the e, State. No very unusual abundance has been reported in any couni
(Abstract, J.A.H.)

Iowa H. E. Jaques (July 24): The codling moth is moderately abunda:
over much of the State.

Missouri R. M. Jones (July 20): The peak of the second brood of the coi
moth hatching is expected around July 28 to August 1. The infe
tion in different orchards varies considerably.

Nebraska M. H. Swenk (July 1-15): The flight of the spring brood of th
codling moth began diminidiing about June 20, and by the end of month had dwindled so that moths were no longer being taken at bait traps. By July 10 no spring-brood moths -ere left aliv-eour insectary, indicating the completion of that brood. The fi:
moth of the first brood emerged on July 4. This is four days earlier than last year, seven days earlier than 1929, and nine
earlier than in 1928. Moths agn appeared in the bait traps on July 6, and have since been taken in increasing abundance. The codling moth is building up an unusually heavy abundance in the
first brood this year.

Colorado C. P. Gillette (July 22): Codling moths are very abundant in
fruit district generally.

Idaho C. Wakel-and (June 30); The prolonged severe winds of early sp:
resulted in very poor spraying at the time of the first cover s] and caused the omission of sprays in some instances, which has sulted in a heavy infestation of first-brood larvae in the apple While the overwintering population was not so large as some yeait is likely that severe injury -ill occur this season because
inadequate cover sprays on:the first brood,.

Nevada T. H. Parks (July 20): The codling moth is very abundant in
western Nevada. Unsprvayed fruit is all worry.

Utah G. F. Knowlton (July 25):The codling moth is moderate to very
abundant in the northern part of the State.

Washingtoi E. J. Newcomer (July 21): Moths of the second brood began fly4
in some numbers July 8, and reached a high point July 20, which
be the raximum~ for the brood in Ya-kima County.

Wisconsin E. L. Cha'mbers (July 21): While the San Jose scale has been confined to less than a dozen counties in Wisconsin and has never
until recently boon found in farm orchards, it has been spreading and a dozen new localties have been. added to the kno-n infested
areas, although none have been found in our corwercial orchards, in
Waukesha, Grant, and Jefferson Counties.


Mississippi J. M. Langston and assistants (July): The San Jose scale has
been reported as very serious from a number of counties during the month, in ;any cases can.Eingtthe death of peach and other deciduous

northeastern corner of the State, in Clinton and Essex Counties,
apple curculios rere pupating by the middle of the month and a few
adults had already emerged by July 13. Late in June the injury was severe in the southern half of the Chemplain Valley. In one
10-acre block from 30 to 40 per cent of the fruit shoved injury.
(Abstract, J.A.H.)

APPLE FLEA WEEVIL (Orchestes palllicornis Say)

Ohio J. T. Houser (July 10): The apple flea weevil is very destructiv
in one orchard in particular.near Chillicothe. There has been a
considerable decrease in abundance from 1930 at Amherst, and it is
scarce in the original center of infestation at Delaware.

COMMON RED SFIDER (Tetranychus ,telarius L.)

Washington M. A. Yothers (July 17): T'iis mite, rhich ascended the fruit
tree trunks in early April, has now become extremely abundant and
injurious, particularly to the fruit and foliage of Dolicious apple

Delaware L. A. Stearns (July 22): First-brood adults of the plurr curculio
have been emerging since early in July. Very abundant in Sussex

Georgia 0. I. Snapp (July 10): Eggs of the second ,enerPtion began to
hatch in the insectary on July 5. ThIne infestation is unusually
light, and to date the insect has caused pra ctically no darage to
the peach crop. (July 20): 51,721 peach drops -ere cut open and examined during May and June and of these only 670, or 1.3 per

Tennessee H. G. Butler (July 29): Second-brood egs -re deposited at the
insectary July 13th and on July 27th the first Tature larvae of
this brood left the fruit. With the beginning of the peach harvest
less than t-o -eeks awayV the curculio fruit infestation is still
so low as to be negli,ible in this area.


Mississippi J. M. Langston and assistants (July): The plum curculio as a

numbers. (Abstract; J.A.H.

ORTENTAL FRUIT MOTH (Lasoyresip molesta Busck)

Connecticut P. Garman (July 23): The first brood is extremely light; the
second brrod is unusually heavy in practically all orchards. Par
Ssitism by Trichograma is mrroderate to light, 20 to 80 per cent.
Parasitism by Macrocentrus and other species is light.

New York N. Y. State Coll. of Agr., Weekly New7s Letter (July): Although
oriental fruit moth larvae were about half gro-n by the middle of
the month their damage sas for the most part to terminal growth
only. However, the first larva to be found in a peach in this part of the State was observed July 13. In the -estern part of

In the southern nart of the State it is only moderately abundant
and there is verr little injury to fruit as yet.

Tennessee H. G. Butler (July 29): Trap records during the present season
have consistently indicated a smaller moth population this year
than last. The percentage of parasitismr noted in field-collected
larvae maturing in July is considerably higher than that of the
June collection. Most of the pearasites so far obtained are
Macrocentrus dolicatus Cress.

Mississip-pi J. M. Langston (July 23): Peach t -its injured by larvae of the
oriental fruit moth were received from Sallis on June 26, from

General J. L. Wdbb (July 28): For the past three weeks this office has
been flooded with inquiries both by letter and telephone for control
measures to be taken for flea infestation of houses. The city of
Washington seems to be pretty well infested as the environs, and we have had inquiries from as far north as Massachusetts. It is a little later than usual and the pests seem to be
more abundant than usunl.

South Carolina W.E. Dove (June 20 to July 20): Infestations of dog fleas under
and residences have been very numerous in South Carolina and Georgia,

Georgia W. E. Dove (July 15): The tropical rat mite was especially
annoying in a residence at Waycross during this spring.

LONE STAR TICK (Amblyomma americanum L.)
South Caroling H. Oa Schroedecr (July 20): This species of tick is very i-m"
portant as a pest of man and wild animals on the islands in the
vicinity of Charleston. They hAve been found to be annoying
throughout the spring months,
Georgia -H. 0. Schroeder and D. G. Hall (June): On Wassaw Island, near
Savannah, the lone star tick was found to be a serious pest of
deer, hogs, turkeys, and man.

A TICK (Argasicdae)

Idaho C. Wakeland (July 23): A tick, close to Ornithodoros turicata
Duges, was collected at Moscow. Four specimens were collected
infesting a sumer cottage. One specimen engorged. Bites on
ear and. face of lady occupant c used painful swelling and heavy
scab formation.


STABLE FLY (StoroxZs calcitrans L.)

Nebraska M. H. Swerk (July 1 -15): Conplaints of severe annoyance to
livestock by the stable fly, which began to come in during the
third week in June, ceased abruptly during the first week in July.


HORSE FLIES (Tatanidae)

South Carolina 17. E. Dove (June 30 to July 20): On June 30 the predacious
wasps known comonly as "horse guardsW' were present at Savannah,
Ga., averaging one to each animal, Rarely a tabanid could be
found. From July 10 to July 20 these wasps averaged two to three to each cow or horse. During this time tabanids could be collected only at protected places away from animals. These wasps occur
throughout Florida as well as South Carolina and Georgia, and are
said to be very effective in o6ntrol, but do not get in their work
until late in the season.

North Dakota A. A. Penn (July 3): The black gad fly (Tabanus atratus Fab.)
was reported as prevalent and annoying cattle in the vicinity of

Golden Valley, Bowman, Williams, Burke, Grand Forks, Dickey, Ward,
and Morton Counties.


STICXTIGHT 13tA (Ehide ha gallinacea Westw.)

Georgia H. 0. Schroeder (June):; An infestation of the sticktight flea
was found to occur near Augusta. It was apparently not due to a
recent importation.


CHICKEN MITE (Dermanyssus gallinae Lg).

North Dakota C. T. Carlson (July 13): Chicken mites are very abundant this



EUROPEAN EARWIG (Forficula auricularia L.)

Oregon D. C. Mote (July 13): The increased number of'requests for information on control indicates that this insect is more abundant
this year.
ARGENTINE ANT (Iridomyrmex humilis Mayr)

California Harold Ryan (June 29): In May we had a considerable number of
inquiries from property owners in regard to winged ants that came
to their notice. In practically all cases the winged male
Argentine ant was submitted for identification. No femrle migratory forms of this ant were turned in.

Mississippi N. L. Douglass (July 18): In the localities where infestations
of the Argentine ant occur the results of the control campaigns
are pleasing in most cases. It is hoped that the only infestation
in Granada County is practically exterminated. Very good results have been obtained in both the infestations in Yalobusha County.
The only infestation in Carroll County looks as though at the
present time eradication will be possible within 'the near future,
Of the three infestations in Montgomery Co., no Argentine ants have
been found thus far this spring at Duck Hill, Miss., and very few at Kilmichael, and while complete eradication at Winona is not in sight yet, a number of the blocks have been cleaned up this year.

CONFUSED FLOUR BEETLE (Ttibolium confusum J.Duv.)

Nebraska M. H. Swenk (July 1): A Cass County farmer found his hay mow
alive with larvae and beetles of this species developing in the
heavy accumulation of hay dust during the last week in June.


Wisconsin E. L. Chambers (July 22): Several serious infestations of the
white-marked spider beetle have been reported in tills in Eau
Claire and Green Lake Counties.


TIMER BEETLE (Nacerda melanura L.)

Massabhusetts A. P. Morse (Jan. to June): There was a local outbreak of this
beetle in a newspaper office at Salem. The beetles were quite
active, disagreeably in evidence while flying about, both day
and evening. They seem to have been brought in through secreting
themselves in the folds at the ends of rolls of newspaper stock imported from Dalhousie, New Brunswick. They are said to breed
in decayed wood and it seems possible tht the large amount of sawdust, bark, and such material in the vicinity of pulp mills
might account for their presence in nibers.

J. V. Schaffner, jr. (July 7): A representative of an insecticide company of Boston brought in specimens of X. nelanura
L. for identification. He reported that these beetles were
sw ming all over an old four-masted schooner which had been
fitted up as a night club and tied up to a wharf in Boston Harbor.
His company had been called on to exterminate this insect. On
July 16 he reported that the breeding places were located in the lower hold where the insects were boring in the timbers and that ihsatoad of the beetles coming from the outside there were swarms
of them trying to get out of the boat.

Al AITOBIID BETLE (Xyletinus peltatus Harr.)

Mississippi J. Milton (July 21): This species had caused dama e to pine
floors in a home at Booneville.



Notes abstracted from "News Letter", July, 1931

(Not .for publication)

PINK BOLL WORM (Pectinophora gossypiella Saund.)

The finding of the first pink bollworms in the 1931 coen crop in the Salt River Valley of Arizona, on May 5 and 6, was mentioned in last month's News Letter. The two fields involved are located about 10 miles southwest of Phoenix and some 15 miles west of the 1930 noncotton zone, in the Laveen section. Since then specimens have been found in two additional fields. On May 11 one larva was found in a field about 6 miles east of the 1930 noncotton zone. An exit hole was found in a green boll from this field on May 22, indicating that the first generation of the current season had already begun to emerge. Since the initial infestation was found, additional specimens have been taken from this field and the two fields about 10 miles southwest of Phoenix mentioned in the July 1 number of the Survey Bulletin. One specimen was taken from a field about 4 miles south of the 1930 noncotton zone on May 29, this being in the Goodyear vicinity.

During May 2,373 samples of bolls were inspected at the San Antonio laboratory, this being the greatest amount inspected any month since the laboratory has been in operation. These samples represented fields in 216 counties in the States of Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, Oklahoma, South Carolina, and Texas. Samples had already been inspected from North Carolina and Tennessee. A total of 7,892 samples had been inspected at the close of May, all with negative results.

XJROPAEN C0 BORER (Pyrausta nubilalis Hbn.)

The first European corn borer pupa found in 1?31, as reported by the Arlington Laboratory, was collected in the vicinity of Arlington, Mass., on April 16, and the first record of emergence, also in that neighborhood, was made on May 22.

GIP SY ,OTH (Porthetria dispar. -.)

In INew Jersey the work which is being done cooperatively by the Federal and State forces consisted mostly of checking up work around previously infested areas. This was practically completed during the month and no infestations were found. 1,any of the Federal men in New Jersey were transferred during the last of May to Massachusetts and Connecticut to assist in the spraying work which was being done there during June.


JAPAITESE 3BTLE (Popillia japonica Newm.)
The earliest emergence of adult Japanese beetles for the season was
recorded on May 23 at Andalusia, Pa., when a single specimen was collected in an outdoor nursery frame. Three beetles were collected on May 30 near Chester, Pa., having been discovered on weeds in a hollow along a creek. These recoveries were of beetles which had overwintered under particularly
favorable conditions as to protection from severe weather. Consequently their transformation into the adult stage does not represent the normal life cykle of the insect in the region of Philadelphia, where the mass emergence of the beetle will not occur until late in June or early in July.

MEXICAN FRUIT FLY (Anastrepha ludens Loew)

Following the finding of an infestation of the fruit fly in fruit
held in storage near Mission, Tex., on April 22, an intensive effort was made to locate and thoroighly examine all fruit held in storage within the quarantined area.

Additional infestations in fruit growing locally in Matamoros were found during the month, bringing the total number of infested premises to 12. On April 15, larvae of the fruit fly were found feeding in halfgrown fruit of Sargentia greqii, one of the sapotes. Larvae were also taken from fruit of the white sapote, Casimiroa edulis, of which there are 5 trees growing in Matamoros.

DATE SCALE (Parlatoria blanchardi Targ.)

During the month of May, 33, 3847 palms were inspected and a single Parlatoria scale was found. This specimen proved to be dead. Daring the past six months the routine inspectors have found only 3 infested palms; on 2 of these dead scale only was found. The scout inspectors, inspecting small plantings, ornamentals, etc., have located 21 infested palms during the same period, 12 in the Coachella Valley, 7 in the Imperial Valley, and 2 in the Tama Valley. Sixteen of these palms were of no value and were dug out and destroyed; the remaining 5 were defoliated and torched. In the corresponding six months a year ago 180
infested paLas were found.

A TIIPS(Frankliniella helianthi Moulton)

An interception of a sotol bloom stalk (Dasylirion sp.) at Presidio, Tex., on March 22, 1931, bearing thrips, was submitted to J. R. Watson, of Gainesville, Fla., who dotermined it 'as thiis species and further remarked: "This is an interesting lot, as it is the first time it has been recorded outside of California, from where it was described. This is also a new host plant and a decidedly different host plant than that from which it was described, namely, sunflowers. I suppose you have no data as to what part of Mexico this came from." Inquiry from R. B. Lattimore, at Presidio, as to the Mexican origin of the host material,

brought the reply that since it came in a truck and the flowers are rather delicate the probability is that it was collected within a short radius from the port, and that search would be made for the parasite in the neighborhood.

The interesting feature in this case is the addition of a new and
unsuspected species to the known hosts of this thrips, and it exemplifies once again the part so frequently played by our inspection force in contributing in an incidental but effective manner to the sum of knowledge on insects and diseases.

Insular Experiment Station, Rio Piedras, Porto Rico.

June beetles, Phyllophaga pp., had so badly stripped the leaves of a young cane field at Isabela early in May according to Dr. G. N. Wolcott that it seemed the plants could hardly recover. However, when I visited it, in company with Dr. Wolcott and J. G. Myers, on June 1, much new growth was present owing to recent heavy rains; the older leaves were badly damaged.

Only two beetles of Phyllopha~a portoricensis Smyth wore observed during three hourst collecting at the several large lights at the Sugar Company's hotel at Aguirre on the night of June2(G.N.W. and M.D.L.). They were entirely absent during the nights of June 27 and 28. (M.D.L.)

Ligyrus turmulosus Burrm. adults were common at the lights at the Sugar Companyts hotel at Aguirre on the night of June 2, but on the nights of
June 27 and 28 only about a half dozen beetles were observed.

The adults of the pink leaf-sheath bug, Lasiochilus divisus ChOampion, were observed in fair numbers at the lights of the Sugar Company's hotel at Aguirre on the night of June 2, but were scarce on the nights of June 27 and 28.

A leafhopper, Protalebra brasiliensis De Long, has been observed
breeding abundantly throughout the month on large patches of Bidens pilosa, locally called margarita- or clavelillo, on the edges of the El Morro Golf Course at San Juan. Mr. Wolcott states that this loofhopper is sometimes abundant on cane growing in weedy sandy fields but that its occurrence on cane is accidental, its common food plant being Wedclia trilobata, ,(Jour. Dept. Agr. P.R. 5 (3): 31, 1921, erroneously det. by Metcalf as Erythroneura comes Say.) Adults were found commonly on carrots by R. T.
Cotton at Rio Piedras in 1917.

On June 2 a scale (Howardia biclavis Comst.), determined by H. Morrison, was called to our attention by Mr. T. B. McClelland, Director of the Federal
Experiment Station at *Uayaguez. It was abundant on the trunks a plpif s of a number of shade trees (Gliricidia sepium) of coffee in a large/experimental plot which Mr. McClelland has been running for some years. He feels that the scale has considerably interfered with the growl7th and production of a number of trees.

The "tvaquita," Diarepos spengleri L., was badly stripping the foliage of a number of young grapefruit trees at the Substation grounds at Isabela on June 1. (G.N.W. and M.D.L.). On June 2, in company with J. G. Myers and G. N. Wolcott and Mr. Herbert Osborn, a section of the Aguirre Sugar Company's properties, Santa Isabel, near Guama was visited to look for egg parasites of Diaprepes. The beetles were exceedingly abundant on a number of good-sized trees of a Ficus, supposedly F. laeviFata, growing along several roads through the cane fields, and much stripping of their

foliage haelQdccurred. 4' number -of b "atches of1-'etg were fond but none appeared to be parasitized, A niber'of-lmoca." Andira ineiriis, H.3.K., trees were' [tiso "rather badly stripped by 'thd beetles lii. the %L-me locality.

A heavy infestation of Corythud~a gossbypii lab~in coc field of lia
beans near Aguadilla has caused appreciable reduction in both quantity andquality of crop. (G..w.)

The Lall armyworm, Laphygaa frugi-perda S.& A., was reported by Dr.
Wolcott- as causing considerable damage during the latter part of the month to ~the alfalfa at the Isabela Substation, The outbxea-k,. however, Was. quickly checked, he reports, by cutting the alfalfa and allowing the imported toads, Bufo inarinus L,, which are numerous, to eat the caterpillars. This insect wa's reported throughh G.N.Wolcott).by T.B,. McClellanad, Dix~ectcir o: the Federal Experiment Station, as causing an outbreak on grass at;.. Mayaguez.

The leaf-tier Dichon.&J~s pgiperatus Wlsm. seemed to be doing about the same amount of damage when' exgzninad, on. June 1 in the experimental- plots at
-the Isabela Substation as during the prerio~.s month. Dr...G.N. Wolcott-i reports that it continued to be'-njurious..during the month.

The canna leaf-tier,- Calpodes etlius: Crtx~r, was observed- to be,
moderately infesting a number of plants bordering a large entrance drive-':* way near the Substation at Isabela on June 1 (M.D.IL., G*N.W*, J.G*Me)o

The monlybug Orthezia iLsiynis Douglas was present on rose cuttings received on June 4 from a g-arden in Santurce. The accompanying letter stated that a number of rose bushes were being rather badly injured by the insects and remedial measures were requested.

lDr .G. N1. Wolcott reports a. high infestation of the pink boll worram, Pectinophora gossyniella Saund., on the first crop of cotton in one field near Aguadilla, often two or three caterpillars being found in one boll or one large caterpillar in a small boll, He states that hard successive rains and the pink boll worrm have caused fully 50 per cent loss of the crop in this field, Mr. E. F. Rorko, of..the San Juan Ginory Co., states that the field in COamuny which showed 6 per cent, 10 per cent, and 18 per cent infested bolls, based on counts of 100 bolls on May 1, May 8, nd June 6, respectively,increased to 22 per cent and 28 per cent on June 13, and 28, respectively. Two other fields at Camuy showed 4 percent and 13 per cent infested bolls on June 17 and still another field 12 per cent on June 28. He further reports that a field at Hatillo in which the crop was almost finished hrad 31 per cent infested bolls by actual count on June 17. The situation is more serious than ever before on the ,whole North Coast since the infestation. is higher earlier in the life of the crop. Excessive rains during. the Spring delayed picking and no cotton was brought until June 3. Juan Pastor Rodriuez, General Agricultural Agent for the South Coast, states that byMay 15, the date set for cor.plotion of the clean-up against pink boll worm, only about 5 per cent destruction of the old plants had been accomplished but that by June 1.about 50 per cent of the old cotton plants in the South Coast had been pulled up and burned and that the work was practically completedd by the.ond of the month. This does not apply, however, to.the towns of Guyama, Patillas, and Maunabo where the crop had been planted later, the last of the cotton crop not being purchased from growers until early in June. Mr. Pastor states that by the end of June a large percentage of the will cotton trees (algoCon sylvestre) along the roadsides in Guyanilla and Yauco had been cut down and burned; that from Penuelas to Guanica nearly all along the road and some in the interior arqu-d :the fields had been destroyed; around Ponce, however, and along the road from Santa Isabel to Guya na, including Slinas, not so large a proportion has been destroyed, efforts being concentrated on destruction of thLo remnants of the cultivated Sea Island crop.

Dr. G. N. Wolcott reports the cotton leaf worm, Alabmma argillacea Hubner, very abundant towards the end of June around Isabela, pnd often causing entire defoliation despite efforts of the growers to control the outbreak. Almost daily rains washed off the poison soon after it was applied, thus rendering control difficult. The outbreak did not spread more than 2 miles south of the North Coast zand .a few scattering caterpillars were just beginning to appear in the cotton around A-uadilla at the end of the month. Dr. Wolcott has observed the moths which were attracted to lights about. the dinner table in the house to feed on the Juices of dead ripe r.,angos. He states that this observation will probably also apply to moths in the field feeding on fruits still on the trees or fallen to the ground.
E. F. Rorke reports that new infestations started up during'June,
in general in the North Coast section but especially about Hatillo, Camuy,
and Isabola, where the cotton plants are large and the crop more concentrated.


The cotton leaf-miner, Nepticula gossypii Forbes and Leonard. Many plants showed evidenc of considerable mining of the leaves earlier in the life of the crop at PeAuelas.

The cotton stainer Dysdercus neglectus Uhler was reported abundant in
an old cotton field long past picking on June 25 at Carolina. D. andrese L., by far the most common of the two here, was almost entirely absent. Specimens were submitted to check the determinations. Mr. Flores now believes that the staineishe reported on in April (I.P.S.Bulletin 11 (4):236, June, 1931) were almost all if not entirely neglectus instead of and.cs One specimen of Oncopeltus aulicus Fab. was brought in but I judge it was probably not feeding on the cotton bolls. (Ismael Flores Lugo, Agricultural Agent,

Dysdercus andreae L. has not been troublesome so far during the month on the North Coast and the blister mite Eriophyes gossyDii Banks is scarce. (E. F. Rorke)

The black scale, Saissetia nigr Neitner, was present in the greatest abundance in Penuelas that I have yet seen in the island, many plants having the stems and twigs entirely encrusted with the scales.

The cotton leaf blister mite, Eriophyes gossypii Banks, was observed
badly irnfesting many old plants in a field from which the drop had already been picked on June 2 at Penuelas.

The infestation of the "pollilo," Cryptotermnes brevis Walk., was
reported in one of the government buildings in San Juan. Upon investigation it was found that many valuable records had become infested, some of then so badly as to have been practically destroyed.

Agrotis ypsilon Rott. constituted the principal pest of corn in the
vicinity of Montemorelos and Linares in Nuevo Leon and on the outskirts of Torreon, Coahuila. In the latter place it also severely attacked wheat. A species of Agrotis was also attacking corn in the environs of IXtlan
del Rio in Nayarit during June.

Peridroma sp. started attacks on corn in the vicinity of Ixtlan del Rio, Nayarit, and Tampico, Tamaulipas, during June.

Heliothis obsoleta Fab. is attacking corn in Lower California in the vicinity of Ensenada, also in the Tepic region of Nayarit during March.


In the middle of May Diatraea sp. appeared on sugarcane in the vicinity of Montemorelos, Nuevo Leon, and was also reported from Linares. This insect also attacked sugarcane in June in Ixtlan del Rio. In the ronth of June Diatraea sp. appeared in the greater p,rt of the Camargo region of Chihuahua in the plantations of corn. It is calculated that 10 per cent. of the crop is injured.

Chilo sp. started attacking sugarcane in June in Ixtlan del Rio, in Nayarit#

Wireworms were one of the principal pests of corn in the vicinity of Montemorelos and Linares in Nuuv ,Leon and were also reported as attacking corn in Colima. Early corn is planted in February and March in-the Tampico, region of Tamnaulipas and larvae of Elateridae destroy the corn when it begins to germinate.

Phyllophaga larvae attacked corn in Colima, appearing in May and doing much damage.

Sphenarium sp. and Taeniopoda eaues Burm. started attacks on corn in the region about Ixtlan del Rio, Nayarit, during June.

Lampazos, Nuevo Leon.

The alfalfa caterpillar Autographa P californica Speyer, which
attacks the leaves and flowers Qf alfalfa, clover,and likewise barley, pea, and cabbage, had been scarce during the period in Lower California, vicinity of Mexicali,.

Cotton is planted in April and May in the vicinity of Yavaros, Sonora, and Anthonomus grandis Boh. causes great daage to this plant every year and requires extensive control measures.- This was one of the principal cotton insects during June in the environs of Mier, Tanulipas, and was also common in Coahuila; although numerous there are no indications that \ they are maIking any intensive invasions this year except in the vicinity of Lagunera where control measures were applied.

Alabama argillacea Hbn. is important in Coahuila when it appears
early but it is not very comnron this year and for that reason is not causing serious injury. In general, it occurs about every four years, and at present is of no importance. It wis, however, one of the principal cotton insects during June in the Mier region of Tamaulipas, attacking the plants when they are a few days old.


Pectinophora gossypiella Saund. has made its appearance in the
plantations of cotton near Cmnargo, Chihuahua, but its greater activities develop in the fall. The damage done in 1930 is es.tipated at 41 per cent. It is common in. Coahuila, in the vicinity of TotreOn; 14though numerous there are no indications tirat they *dre Yhoaking any inteisi've invasions this year, except in.te. viciniity of Lagunera where control measures were applied.
