The serious grasshopper situation in the Great Plains continued
throughout August. During the month many reports were received of the hop-
pers defoliating shade and fruit trees, where other vegetation had been
destroyed. Large populations of grasshoppers were also reported from the
East Central States.

Distribution records indicate that Mormon crickets are widely preval-
ent in North Dakota and Montana.

In the southern Mississippi Valley the fall armyworm is moderately
abundant in man. places.

Japanese beetles show a notable increase in intensity this year in
Connecticut and New York.

Say's stinkbug was found in Dickey County, N. Dak., east of its pre-
viously known distribution, and Scotts Bluff County, Nebr., and was present
in damaging numbers in north-central Montana.

Hessian fly surveys indicate severe infestations in the East Central
States, extending from the southwestern corner of Ohio, across the southern
half of Indiana and the southern two-thirds of Illinois, with moderate
infestations extending into east-central Missouri.

The corn ear worm was notably scarce throughout practically the entire
country, with the exception of a rather heavy infestation in the Great
Basin, Utah.
Peak flights of adults of the codling moth occurred during the first
week in August in New York State, during the third week in August in Indiana,
and during the second week in August in Washington State. Infestations in
the East Central States are generally quite heavy.

Extensive injury to the terminal growth of potatoes by a plant bug,
Lygus elisus Knight, was reported from North Dakota.

Very severe damage to late tobacco by the tobacco flea beetle was
reported from North Carolina.

The cotton boll weevil was reported as rapidly increasing in numbers in
North and South Carolina, Alabama, parts of Mississippi, and parts of Texas,
while in other parts of Texas there was a decided reduction in populations.




In general, bollworm infestation is subnormal throughout the Cotton
Bolt, with a few localities reporting damage.

Leafworm damage has been checked in the lower Mississippi Valley
by hot, dry weather, a few localities reporting damage.

The pink bollworm has beeoon found in the lower Rio Grande Valley, at San
3onito, Brownsville, and Rio Grande City. This is the most serious cotton
insect of the month,

The alder flea beetle was unusually prevalent throughout the northern
New England States and northern New York. A severe outbreak of this insect
occurred also in the Targhee National Forest in Idaho. A blowfly, Paralu-
cilia fulvipes Macq., formerly only known from the coastal part of California,
was collected in several localities in Arizona. Although this species is
primrnrily a carcass breeooder, there is some evidence that it may cause myiasis
in animals.


Severe drought and high temperatures in the Prairie Provinces have
-'.-raiv.ted the grasshopper situation. In Mr-nitoba the grasshoppers are
doing considerable damage to late crops in southwestern sections and in the
Haskett district, but are comparatively scarce in the central part. Egg
laying commenced early in August. In Saskatchewan the infestation of adults
is generally heavier than that of last autumn. EgF laying was general in
the northwest at the end of July and was beginning in southern districts.
Concentration of the grasshoppcr-. for egg laying resulted in some head
damn7e to grain crops. Effective baiting was carried out throughout the
entire west-central portion of the province, where the infestation was most
severe. In Alberta grasshoppers are widespread and injurious. They have
mi-r-'tod to good crop areas and are causing some losses to wheat, but are
partrticularly serious on coarse grains. A heavy increase and partial
outbreak over most of the Dry Belt in the interior of British Columbia is
reported and the outlook for 1937 is considered serious.

Blister beetles, of which Nuttall's blister beetle is a prevalent
spcci ,s, are abundant in areas of grasshopper outbreak, in the Prairie
Provinces and the interior of British Columbia, causing damage to shrubs
and garden plants.

The moth flight of the pale western cutworm had started in southern
Al'erta in mid-August and the abundance of the moths indicates a severe
infestation in 1937.

Infestations of the wheat stem sawfly are severe generally in Saskat-
chewan and drmnre is increased by premature ripenir..: nand thin crops. In
Alberta the wheat is being cut '' the ?r"'fly in all districts south of
Stettlor, and especially in areas of good crop.


The wheat stem maggot is not so abundant in Manitoba as in past
years, but in northeastern and eastern districts of Saskatchewan it is
causing some damage to wheat by producing white sterile heads.

The wheat midge has caused considerable loss in spring wheat in
the Victoria district, Vancouver Island. It is also present in serious
numbers at Lumby and Salmon Arm, in the interior of British Columbia.

Reports indicate that the Colorado potato beetle is unusually abundant
in Ontario and the Prairie Provinces. In Saskatche".an infestations were
found to occur almost as far north as the limits of settlement.

Following the occurrence of large and extensive flights of the beet
webworm in the Prairie Provinces this spring, weeds, sugar beets and garden
plants in many districts suffered injury from the larvae.

An increase in the European corn borer infestation in southern
Ontario has occurred, but probably there will be little commercial loss to
the corn crop.

The gladiolus thrips is now well established on southern Vancouver
Island, in British Columbia.

The European earwig is more numerous than ever in coastal sections
of British Columbia and is causing many complaints.

The pea moth is prevalent in pea-growing sections of the Gaspe Penin-
sula, Quebec.

Heavy infestations of the red turnip beetle, with consequent losses
to garden plants, are reported in parrts of Saskatchewan and Alberta.

The roundheaded apple tree borer is more numerous than in previous
years in orchard sections of southern Quebec. The apple curculio and the
plum curculio are very injurious to the apple crop in this region, as the
crop is very light, following destructive spring frosts.

The rosy apple aphid was the outstanding insect pest early this
summer in orchards of the An-.apolis Valley, Nova Scotia. It was also more
abundant and destructive than for many seasons in the Niagara district,
Ontario. In the latter area, what threatened to be an unusually severe
outbreak of the apple aphid was brought under control by extremely hot and
dry weather.

The oriental fruit moth infestation in southern Ontario continues at
a very low level and the insect is of much less importance than during any
season since it became generally distributed over the peach-growing districts
of the province. The peach borer is iLnusuall7 injurious in the Niagara
There has been a pronounced reduction in the population of grape leaf-
hoppers in the Niagara district, and it is believed that the outbreak, -hich


cnmmonced in 1931, is definitely on the wane.

The European larch sawfly has increased in numbers throughout the
.t'hern half of Now Brunswick and in some parts of Nova Scotia. Slight
damage at scattered points has occurred in Prince Edward Island. In the
Fernie area of British Columbia, a great reduction in this species is
apparent this season.

Outbreaks of the yellow-headed spruce sawfly have been very severe
in many parts of the three Prairie Provinces. The only areas that have
escaped have beeoon the most southerly portions.

Caterpillars of the cecropia moth have done considerable to
boxelder in southern Saskatchewan.

The satin moth infestations in the Maritime Provinces have been more
severe and widespread than in previous years.




Vermont. H. L. Bailey (August 19): Grasshoppers, Melanoplus sp., are
very abundant in scattered spots about the State. Danville, in
Caledonia County, Bridport in Addison, Newfane in Windham, 'and Tun-
bridge in Orange are localities of greatest abundance.

Ohio. T. H. Parks (August 25): Grasshoppers have increased in number
during the summer and now approach normal numbers in many meadows
and pastures. Notwithstanding the extreme drought, we have had call
for aid in controlling grasshoppers in only two counties, in each of
of which the outbreak was local.

Indiana. C. M. Packard and assistants (August 13): Grasshoppers are very
abundant and doing serious damage in many cornfields in Tippecanoe
County and other northern localities.

Illinois. W. P. Flint (August 20): Nearly all grasshoppers are now in the
adult stage and mating is taking place generally. No eggs have been
found. Many cornfields will suffer 25 to 50 percent loss of crop and
a few fields will be completely destroyed.

Michigan. R. Hutson (August 24):. Numerous small local infestations of
grasshoppers, principally M. mexicanus Sauss., have been reported in
southern Michigan. Injury to young orchards fairly prevalent.

North Dakota. F. Gray Butcher (August 18): Grasshoppers continued to cause
concern during the past month, being reported as from moderately to
very abundant in 35 counties. Injury to gardens and late flax fields
in the drought area has been severe. A survey being conducted indicates
that M. moxicanus is the predominant species.

Iowa. H. E. Jaques (August 23): Grasshoppers continue to be the most
serious insect problem. Recent trips through many counties in western
Iowa revealed great abundance. In some districts the weeds are all
stripped to the main stem and even the thistles are being oaten.

Missouri. H. Baker (August 26): Grasshoppers have defoliated many young
orchards throughout the section around Saint Joseph, where the trees
have not been protected by bait and sprays. Older, bearing trees have
suffered little damage, although some isolated trees, trees in outside
rows, and low hanging limbs on other trees have been defoliated.

Nebraska. M. H. Swenk (August 24): There is quite a largo grasshopper
population. Damage to the leaves of trees was commonly reported during
the last 10 days in July, and loss of corn was complained of until about
August 10, when the destruction of the corn by the drought reduced
the reports of crop damage.

Kansas. H. R. Bryson (August 19): Grasshoppers (Melanoplus spp.) continued
to be the outstanding pests last month. Visits to western and north-
western counties revealed the fact that few trees bordering wheat
fields escaped defoliation. Cornfields were completely stripped of
their leaves. In many instances the stalks were eaten close to the
ground. Sorghums for the most part were not attacked. The defoliation
of orchard trees and alfalfa fields is general. The absence of weeds
and succulent vegetation in waste areas brought about by the drought
has forced the hoppers to the green cultivated crops. The population
is such that the second generation and adults of the first generation
will cause considerable injury to fall-sown alfalfa and winter wheat.

Oklahoma. C. F. Stiles (August 19): For the past 3 weeks grasshoppers
have been defoliating many of the shade trees along the streams and
along the fence rows through the northeastern and western parts of the
State. In Mayes County in the northeastern and Woods County in the
northwestern part of the State, practically all the trees, including.
fruit trees, have been defoliated. No doubt many of the trees will die,
because the hoppers are getting every tender shoot that appears. They
have booeen extremely hard to poison during the hot weather, as they are
not feeding much on the ground and are hunting cooler, shady places,
such as the north sides of fence posts and trees. Approximately 2,000
tons of bait have been prepared and distributed throughout the State.

1ontana. A. L. Strand (August): About 3,000 tons of bait have been used in
Montana this season, mostly in the counties along the Yellowstone River,
where infestations of grasshoppers in irrigated crops have been very

UtJih. G. F. Knowlton (July 31): Grasshoppers are much more abundant in manr
parts of Cache County than they were a year ago. Most abundant in
fields are M. packardii Scudd., M. moxicanus, M. femur-rubrum Deg., M.
bivittatus Say, Aulocara olliotti Thos., and Dissostoira carolina L.
(Auwuzt 9): Grasshoppers have caused severe stripping of wheat and
alfalfa north of Paragonah, and much damage west of Parowan in Iron
County. Many M. bivittatus and M. packardii have died of disease.

LUBBER GRASSHOPPER (Romalea microptera Beauv.)

Alabama. J. M. Robinson (August 13): Lubber grasshoppers were reported as
very abundant, attacking flowers on lawns at Uniontown on August 3.

MORMON CRIC1eT (Anabrus simplex Hald.)

North Dakota. F. Gray Butcher (August l1): The distribution of Mormon
crickets over the State is increasing. Reports indicate that the
crickets are present rcncrally throughout Ward County, have also boon
found in numbers in Burleigh and Stark Counties, nnd a few individuals
in Divide and Pierce Counties.

Montana. A. L. Strand (Auust): Mormon cricket infestations are about the
same as in 1935, 'mith sone extension of the outbreak into southeastern



Montana. The area includes the territory bounded by Glacier, Pondera,
Teton, Cascade, Meagher, Park, Carbon, Big Horn, Powder River, Custer,
Rosebud, Musselshell, Golden Valley, Whoatland, Judith Basin, Chouteau,
Liberty, and Toole Counties. Smaller infestations are present in
Sanders and Lake Counties, west of the Divide.

PALE WESTERN CUTWORM (Porosagrotis orthogonia Morr.)

Montana. A. L. Strand (August): Damage by the pale western cutworm was
more severe than in any year since 1932. The main area affected lies
in north-central Montana in Cascade, Teton, Pondera, Toolc, Liberty,
Hill, and Chouteau Counties.

FALL ARMYWORM (Laphygma frugiperda S. & A.)

North Carolina. C. H. Brannon (August 15): This insect is still causing
damage in many sections of the State.

Georgia. T. L. Bissell (August 29): Tho' fall armyworm is very abundant on
grass at Experiment.

Tennessee. G. M. Bentley (July 22): The fall armyworm has been doing
serious damage in the following places: Locks Creek,in Cannon County,
on millet, sorghum, and corn; Tiptonville, in Lake County, on June 1,
on alfalfa.

Alabama. J. M. Robinson (August 13): The fall armyworm was moderately
abundant near Huntsville during the last week of July.

Mississippi. C. Lyle (August 24): The southern grassworm was reported
injuring corn at Yazoo City on July 31 and at Greenwood on August 3.
Inspector Jack Milton reported it as causing moderately severe damage
near Brandon. At State College it was causing serious damage to young
corn on August 22.

APRMYWORM (Cirphis unipuncta Haw.)

Kentucky. M. L. Didlake (August 24): Late summer brood outbreaks in
counties of southern and central Kentucky--Russell, Metcalfe, Wayne,
Cumberland, Hart, and Clinton. They have eaten crabgrass in fields of
lespedeza and soybeans, but the legumes were not attacked. Principal
damage was done to corn, the blades being eaten off nearly up to the
ears. Many of the worms have eggs of tachinid fly parasite on them.

BEET WEB7ORM. (Loxostege sticticalis L.)

Montana. A, L. Strand (August): The second generation of larvae has not
shown up, although the flight of moths was enormous. This is the first
year since 1932 that an outbreak of this species has occurred.

A. L. Gibson (July 6): Range plants and weeds, including Russian-
thistle, have been severely defoliated at Whitehall, in Jefferson
County. This is the first record in this area.


',:r. G. F. Knowlton (August 19): Larvac are leaving Russian-thistle, upon
which they are abundant, and moving to potatoes, alfalfa, and garden
vegetables in the Panguitch and Junction areas. (AJuust 24): Beet
Sobrvbworms are damna-ing suw-ar beets in the Price-Castle Dale area, and
:-reo moving from weeds to potatoes at Panguitch and Junction, causing
considerable injury. Vegetables in gardens are also damaged when vweed
hosts are abandoned.

WIREWOLMS (Elateridae)

Alabama. K. L. Cockcrh-m (August): It is estimated that there has booeen a
potential reduction in price of 20 cents for each 100-pound bag of
potatoes produced in Baldwin and Escambia Counties this year, owing to
damage to the tubers by the Gulf wireworm (Heteroderes laurentii Guer.).
A total of approximately 992,500 100-pound ba,-s were produced in these
two counties this season.

Mississippi. J. P. Kislanko (July 30): One adult of H. laurentii was col-
lected at Hattiesburg, Forrest County, in garbage. This is the first
record for the county.

North Dakota. F. Gray Butcher (August 18): In some of the potato-growing
areas, especially in the Red River Valley, Ludius spp. and Limonius spp.
have been causing considerable injury to the developing tubers.

WHITE GRUBS (Phyllophaga spp.)

Indiana. P. Luginbill and H. R. Painter (July 30): White grubs seriously
damaged a lawn near Culver. Infestation averaged 7 grubs per square
foot. The grubs are maturing, therefore they belong to brood C, the
adults of which will onmrge next spring. The corn in our variety-test
plots at Crown Point shows serious damage, many plants being practically
destroyed. Infestation averages 5 grubs per hill, with a maximum of 11.
These are second-year grubs belonging to brood A, the adults of which
will emerge in the spring of 1938.

Michigan. R. Hutson (August 24): White grubs have been reported as working
on blueberry at South Haven; also causing trouble on dahlias at East
Lansing, and to corn at Plain'w'ell.

Minnceoto. A. G. Ri-ufles and assistants (August): White grubs very abun-
dant in M1-"vior, Fillmore, Dakota, and Winona Counties.

lo)braska. M. H. Swenk (Auust 24): Complaints of injury to I.wns were re-
ceived from Buffalo and Madison Counties on July 24 and August 17,
respectively, and to a strawberry bed in Franklin County on July 30.

JAPANESE BEETLE (Popilia .Japonica Newm.)

Connecticut. W. E. Britton (August 21): A considerable increase in numbers
over last is noticed in Hartford, Now Haven, and Bridgeport.
Rivcrzide Park, Hartford, is heavily infested and soil treatment will


be started next week. Specimens of adults have been received from
Hamden, Hartford, New Canaan, New London, and three lots from.New

Massachusetts. L. H. Worthley (August 10): On the first survey of a green-
house in Springfield one Japanese beetle was collected.

New York. R. D. Glasgow (August 19): The Japanese beetle is reported by
State Bureau of Plant Industry Inspectors as notably more in evidence
on the wing this season in parts of Westchester County and the lower
Hudson Valley than it wvas last year.

Pennsylvania. L. H. Worthley (August 10): A number of new infestations
were found in nurseries in southeastern Pennsylvania, and a single
new infestation was discovered in an establishment in the north-central
part of the State. There has been a decided decrease in the number
of beetles present in Philadelphia this year.

Maryland. L. H. Worthley (August 10): Three beetles were found in a nursery
located outside the regulated area at Timonium, Baltimore County.

ASIATIC GARDEN BEETLE (Autoserica castanea Arrow)

New York. R. D. Glasgow (August 18): The Asiatic garden beetle has been
reported by State Bureau of Plant Industry Inspector to be unusually
abundant in parts of Westchester County this season, where the adult
beetle has caused annoyance by entering houses.

SAY'S STINK BUG (Chlorochroa sai. Stahl)

North Dakota. F. Gray Butcher (August): Say's plant bug was collected in
wheat fields in Dickey County during the latter part of July. This
appears to be the known eastern limit of its distribution in the State.
The first record of its presence in North Dakota was from southwestern
counties, Billings and Bowman, in 1934.

Nebraska. M. H. Swenk (August 24): Specimens were received from Scotts
Bluff County on July 20.

Montana. A. L. Strand (August): Say's plant bug is present in damaging
numbers over a wide area in north-central Montana.

COMMON RED SPIDER (Tetranychus telarius L.)

Ohio. T. H. Parks (August 25): The common red spider has been very serious
on many ornamentals and some vegetables. We received specimens of bean
plants from Marietta showing very serious injury from this pest.



Michigan. R. Hutson (August 24): Red spiders are very numerous on all
sorts of deciduous trees, including orchard and shade trees in Lansing,
Jackson, Monroe, Adrian, and Albion.

Kentucky. M. L. Didlake (August 24): Red spider abundant on dahlias at

North Carolina. C. H. Brannon (August 10): We are experiencing red spider
damage quite extensively on cotton.

Alc.b'a. J. M. Robinson (August 13): Red spider was reported attacking
butter beans at Moulton on July 30, having spread from violets and sun-
flower plants near the ed-e of the garden.

Mississippi. C. Lyle (August 24): Damage to phlox from red spider was
reported from Aberdeen on August 10. It was reported as moderately
abundant on ornamentals at Meridian and Jackson.

Missouri and Kansas. H. Baker (August 26): Red spider can now be found in
all orchards in the section around St. Joseph, Mo., and Wathena and
Troy, Kans. It has done and is still doing much damage.

TTtnh. G. F. Knowlton (August 14): Red spiders are damaging corn at Cannon-

California. H. J. Ryan (August 27): Damage by the two-spotted mite became
suddenly apparent in August over about 3,000 acres of English walnuts
in the San Fernando Valley. This is the first time this mite has been
reported in the San Fernando Valley as doing serious damage. Occasional
instances of minor injury have occurred previously in other parts of
Los Angeles County, where a general infestation with a light population
was found this year.



HESSIAN FLY (Phytophaga destructor Say)

General. C. M. Packard (August): The results of a survey of hessian fly
conditions at harvest time are being published under date of August 31,
1936 as supplement to No. 4 of the Insect Pest Survey Bulletin.

Ohio. T. H. Parks (August 25): The following is the result of an analysis
made of 122 puparia in Pickaway County on August 20: Live larvae 2.7
percent; parasitized, 44.4; dead from causes other than parasitization,
52.9; total dead, 97-3. With such high percentage of mortality, it is
doubtful whether the fly will be a serious menace this fall in any part
of Ohio.


Indiana. C. M. Packard (August 13): Infestations at harvest tine were light
in the east-central and northeastern parts of the State. In the
remainder of the State many fields were heavily infested, with atten-
d.ant prospects of infestation in the wheat to be sown next fall.
These prospects are being materially reduced by continued drought
and high mortality of the puparia.

Illinois. W. P. Flint (August): The hessian fly situation has chinwed
markedly since the fall of 1935. At present there is a general moderate
to heavy infestation in all parts of Illinois, with the exception of
approximately the northeastern fourth of the State, whore the infestation
is low, running from 3 to 8 percent. In all other sections cf the
State the infestation will run from 15 to 50 percent and will average
about 30 percent for the western and southern sections, with the high-
est infestation in the State showing on the east side of Crawford and
Lawrence Counties. Owing to the extremely hot and dry weather, there
has been a high mortality of the fly in its summer, or flaxseed, stage.
It is probable that the infestation this fall will be moderate, even
in areas where the infestation last spring was high

WHEAT JOINTWOPPM (Harmolita tritigi Fitch)

Illinois. W. P. Flint (August): The wheat jointworm is of no importance
in Illinois, except in the southern fourth of the State. It is
fairly abundant south of a line drawn through southern Madison,
Clinton, Marion, Clay, Zichland, and Lawrence Counties. North of this
line it is of no consequence.


CHINCH BUG (Blissus leucopterus Say)

North Carolina. C. M. Brannon (August 16): Late corn in Pitt County is
being seriously damaged.

Indiana. C. Benton (August 13): First-brood adults still numerous and
mating. Second brood now in from first to fifth instar and abundant
in many fields in Tippecanoe County. Little mortality. Conditions
mostly favorable to development.

Illinois. W. P. Flint (August 20): Second-brood bugs have developed in
moderate-to-large numbers over most of the central and northwest-
central parts of the State4It is still too early to make any predictions
for next year, but apparently there will be a rather heavy carry-over.
The infestations are, as in 1935, very spotted.

Iowa. H. E. Jaques (August 23): Chinch bugs have done some rather serious
damage in southern Iowa.

Kansas. H. R. Bryson (Au-'ust 22): Chinch bugs may be found in corn and
sorghum fields in about all stages. They are not present in alarming



CORN LEAF APHID (Aphis naidis Fitch)

Tennessee. G. M. Bentley (July 22): Corn leaf aphid reported by County
'W-ent of Cannon County ao causing considerable da-ago on sorghum at

CORN LANTERN FLY (Poregrinus maidis Ashm.)

Mississippi. C. Lyle (August 24): Three or four heavy infestations of the
corn lantern fly have been observed on late corn in Jackson and
Harrison Counties by Inspector H. Gladney. On August 22 a heavy infes-
tation of this insect was noticed on young corn at State Collc:e.

COPIT EAR WORM (Heliothis obsoleta F.)

Connecticut. N. Turner (August): In southern Connecticut about 2 percent
of the early sweet corn was affected. The second generation has not

Maryland. G. Myers (August 25): Around Rockville the field corn is re-
markably free from infestation by the corn ear worm. We have not
seen a single worm in the sweet corn in our garden.

Cio. T. H. Parks (August 25): Corn ear worms are very scarce on market
garden corn. No complaints have been received and personal inspections
revealed very few damaged ears. Infestations in greenhouses have
been reported. These probably were due to the fact that the insect
overwintered there.

Indiana. E. V. Walter (August 13): Extremely scarce in corn at Lafayette.
Early worms have all matured and left the corn. No eggs have been
seen since early July.

Illinois. W7. P. Flint (August 20): Corn ear worm is very scarce in the
State. Examinations of canning corn show only from 3 to 5 percent

Iowa. H. E. Jaques (August 23): Many counties report moderate to heavy
damage from corn ear worms.

Tennessee. G. M. Bentley (Aujust 19): The injury is less this year than
it has been for several years generally throughout the State.

Alabama. J. M. Robinson (August 13): The corn ear worm is very abundant
in cL;ntral Alabama.

Utah. G. F. Knowlton (August 29): Damage to corn is somewhat lighter
than it has been for 2 years. Injury to tomato fruit in northern
Utah ranges from 3 to 6 p-rcent. The highest injury is approximately
11 percent in one field at Corinne,


CORN ROOT WORM (Diabrotica longicornis Say)

Minnesota. A. G. Ruggles (August 22): The western corn root worm was re-
ported as doing damage at Willnar, Kandiyohi County.


PEA APHID (Illinoia pisi Kalt.)

Georgia. 0. I. Snapp (July 23): Aphids were very abundant on and caused
considerable damage to field peas at Fort Valley during the latter
part of July.

MEALYBUGS (Pseudococcus sp.)

Georgia. J. R. Thomson, Jr. (July 23): Mealybugs are more abundant than
usual on field peas and other plants at Fort Valley.


SOD WEB37ORMPS (Cranbus spp.)

Kentucky. M. L. Didlake (August 24): Second-brood adults are more numerous
than at any time this season--August 5 to 20--at Lexington.

California. J. C. Elnore (August 18): The sod webworm has become very des-
tructive to new lawns in the San Gabriel Valley. The population
ranges from 5 to 10 per square foot. All new lawns in this area are

CHINCH BUG (Blissus hirtus Montd.)

Rhode Island. A. E. Stene (August 26): For the first time in 25 years the
chinch bug has been sent into the office with a complaint that it is
destructive to grassland. Not commonly present in injurious numbers
in Rhode Island.


BELLA MOTH (Utetheisa bella L.)

Alabama. J. M. Robinson (August 13): Larvae are appearing in large
numbers on Crotalaria at Crossville.


TERMITES (Isoptera)

Louisiana. B. A. Osterberger (August 3): About 60 percent of the stalks
in a low spot in a sugarcane field at Anchorae, West Baton Rouge
Parish, were darmaged by termites. The feeding was near the surface of
the ground and in some instances the entire pith was destroyed.




CODLING MOTH (Carpocapsa pomonella L.)

ITuw York. D. W. Hamilton (August): At Poughkeepsie comparatively heavy
moth captures have' continued in light and bait traps since July 26.
Peak flight of first-brood adults occurred on the nights of August 2
and 3. Several of the poorly sprayed orchards are from 20 to 50
percent injured.

Ohio. T. H. Parks (August): Heaviest second-brood bait-pan catch was made
between July 15 and 22. Another peak occurred on August 1. New lar-
val entrances were appearing in such numbers as to justify a special
spray during the second week of August in a few northern orchards.
Thile the codling moth has made a remarkable come-back during the dry
season, the situation is not serious except where spraying for the
second brood was omitted.

Indiana. L. F. Steiner (August 25): Activity of second-brood adults at
Bicknell apparently reached its peak on August 19 when the catch in

'-luth Carolina. F. F. Bondy and. C. F. Rainwater (August 22): Boll weevils
rire steadily increasing in numbers and are migrating frcm the old to
the younc cotton. (August 29): In the young cotton sone fields increased
from 6 to 50 percent in 1 week and much young cotton has stc:red bloom-
ing because of weevil dannge.

3 "r-'ia. P. M. Gilmer and P. A. Glick. (August 15): Boll weevils
are moderately numerous in upland cotton and are increasing in Sea
Island, the infestation being approximately 17 percent, as compared to
about half that during the previous week. (Auust 22): Cotton showing,
second growth is now beginning to produce small numbers of squares,
almost 100 percent of which are injured. On Sea Island cotton the increase
is causing nome injury. On August 17 approximately 12.5 percent of the

20.46 percent, as compared with 13.67 percent the previous week.

E. W. Dunnam and J. C. Clark (Auunt 15-22): Boll weevils arc
becoming very scarce at Stoneville.


Louisiana. R. C. Gaines and assistants (Aug.ust 15-29): The numbers of

: Auust 21--- : 69 9 : 33
j Auust 29--- : 63 : 2 2 : 2
Mr. Young and assistants examined 7,200 squares in plots that had re-
ceived no treatment and. found an avern.a.eo square infestation of 37.3
percent. This infestation ranged from 16.7 to 66.2 percent for the
week ending August 15.

Arkansas. D. Isely (August 22): The boll weevil is of no economic inv'ort-
anco in any part of Arkansas, probably because of the prevailing severe
drought and high temperatures.

Oklahoma. C. F. Stiles (Au,-u't 19): If the hot, dry weather continues for
another 10 days boll weevil da-iaje throuiih the State will perhaps be
the lightost on record since all of Oklahnoma has been infested with the
weevil. The heaviest infestation last week in southeastern Oklahoma
was 0.5 percent.

Texas. F. L. Thorns (Au!-ust 7): The'avera'e* number of squares punctured by
boll weevils in the se.-cral sections of the State are as follows:
Southern, 60 percent; southeastern, 2o percent; south-central, 10;
north-central, 5 percent; northern, 4. These figures ar. based on
cxanination of 33 farms, some of which had been poisoned for leafworms
and weevils. (August 28): The infestation is comparatively light
in many fields but is increasing, following the setback received during
the hot weather of about 2 weeks ago.

R. W. Moreland (Augiust 1): Mig.ratinn has been Toing on near College
Station for some tine in the upland cotton, as thQ infestation has
built up rapidly durin.- the past 2 weeks. :.xa-iined 5,400 cotton squares
in upland fields during the week uand 1,500 of these were in checks, where
804 punctures were found. The infestation ranged from 42.7 to 64.0
percent with an averar1e of 53.6 percent; 2,700 squares wore examined in
plots that had received more than a presquare application and 870
punctures were found. The infestation in these plots ran--ed from 6.3
to 57.7 percent, with an avera-go of 32.2 rercnet.

K. P. Ewing and R. L. McGarr (A,17u:t 15): At 1'rrt Lavaca general
weevil infestation is reduced frmnn last wcck. Inf s.tAtion records made
in the check plots in the weevil exyerironts in Jackson Coiuty this
week average 22.4 percent puncturedc squares, as coriparoed with 43.9
percent last week. The reduction is no doubt clue tc poisonin- f r leaf
worms (Ala -1."a riillacca Hbn.), along with the hot, dry weather.

Mexico. C. S. Rud1e (Auust 1i): Infestation nt T1lrJualil.o, rwi-mgo,has in-
crease, rTpidly in the past week. In sone re :ions the infco-ation is
from 70 to gO percent in squares and from 15 to 50 percent in bells.



PIP.1: BOLLWORMP (rectinophora gosspiella Saund.)

Texas. F. L. Thoras (Auriist 21): By far the most important event of the
week was the finding of the pink bollworm in the lower Rio Grande
Valley by men from the Bureau of Entomology. The announcement Tuaesday
of the finding of 15 worms at San Benito and 4 at Brownsville is of
sufficient importance to cause the gravest concern to all of Texas and
to southern Texas in particular. The finding of 276 specimens at
Matamoros and a few others at Reynosa, Mexico, 50 miles up the river,
indicates that it is pretty well established on the Mexican side
opposite Camv-ron and Hidalgo Counties. (August 28): Four counties,
Cameron, Hidalgo, Starr, and Willacy, have been quarantined because
of the discovery of pink bollworm in Cameron County.

A. J. Chapman (August 15): Infestation counts were made in 13 fields
at Presidio during the week. These fields averaged 6.82 percent of the
bolls infested, the infestation ranging fr-m 0 to 46 percent. (August
22): Boll infestation records were -aade in 11 fields. The average
infestation in these fields was 31.55 percent, ranging from 1 to 95
percent. Infestation in 8 of the 11 fields last year was 12.25 as com-
pared with 34.S8 percent this year. (August 29): Boll-infestation
records wore made in 10 fields. The averaE:e infestation in these fields
was 29.60 percent, ranging from 7 to 61 percent. Infestation in 9 of
the 10 fields last year was 17.67, as compared to 26.33 percent this

Mexico. C. S. Rude (August IS): The pink bollworm infestation is steadily
increasing at Tlahualilo, Durango. Some evid -nces of migration are
noticeable. An infestation of 70 percent was observed in a field where
the previous infestation was only about 10 percent. The heavy infes-
tation was nearly all first-instar larvae. (August 25): In most parts
of the Lag-'-a the infestation is around 80 percent. Migrations from the
sections of early infestation have started and probably the entire
Laguna will soon h.v.- a rather general infestation.

specinr- .s have bcen observed at Tallulah. (August 29): Specimens can
br)e foun5 in most fields at T-illulah.


Texas. F. L. Thomas (August 7); Cotton bollworms are causing severe injury
where the fields were overflowed and on river bottom lands that re-
ceived heavy rains about July 1. Injury seems to be greatest in the
Brazes and Colorado River bottoms and on creek bottom lands of central
and southeastern Texas. (August 21): Early this week the second
generation of cotton bollworm to attack cotton began to cause injury to
squares. Notwithstanding the hot weather of last week and wilting of
cotton in many fields, a good percentage of the young worms were reaching
the squares.

K. P. Ewing and R. L. McGarr (August 15): A few scattered bollworms
observed doing damage in a good many fields around Port Lavaca. (August
22): During the week there has been a very conspicuous increase in infes-
tation and damage in the Port Lavaca district, particularly in the river
bottoms and in fields where the cotton continues to make good growth.
Bollworms became a very serious factor in the field-plot experiments at
Edna during the week. Infestation records in the 11 cuts under observa-
tion showed an average of 11.2 percent of. the squares infested. The
highest average for a cut was 16.2 percent, while in some plots the
infestation was as high as 25 percent. Most of the worms were small and
perhaps 95 percent of the damage was confined to the squares.

R. W. Moreland (August 1): Examined 4,000 cotton terminals on six
different plantations near College Station during the week and found 140
bollworm eggs and 176 bollworms ranging in size from first instar to
full grown. The eggs averaged 3.5 per 100 terminals and the worms .4.4.
(August 15): Examined 5,4400 cotton terminals during week and found S79
eggs. Eggs ranged from 6 to 40 per 100 terminals, with an average of
16.3 as compared with an average of 2.4 eggs per 100 terminals for the
past week. During the week ending August 17, 1935, 2,400 terminals were
examined and 1,g06 bollworm eo-s were found. Egs ranged from 60 to s4,
with an average of 75 per 100 terminals. (August 22): In examining 1,500
cotton terminals, 10 per point, at 150 points in experimental plots,
264 eggs were found, or an average of 17.6 eggs per 100 terminals. This
is slightly higher than for the week ending August 15.

Mississippi. C. Lyle (Auwust): A specinmen was collecte'l in a hone at New
Albany on August 11, One killed was found full of blond and an occupant
of the room had an inflamed place on the arm, probably due to the bite
of this insect.

ANTS (Fornicidae)

Mississippi. C. Lylo (August 24): :Iu'zrous complaints of ants have b'en re-
ceived throughout the month. Solenopsis xylQni McCook was causing serious
trouble. The Ar.-entino ant (Iridomyrmex humilis Mayr) has been the
source of numerous complaints also, while a few correoI.ondents have
sent in the tiny black ant (Wnnomorium minimum Buckl.).

Nebraska. M. H. Swenk (Au-iist 24): From Hall County on Au-ust 11 came the
complaint that the carpenter ant (Ca'-.1 r.notus herculoanus i:cnnsylvan.icus
Doi-.) -',s abundant on elm trees in that Iccality.

A'J.'ICAN DOG TICK (Dormacentor variabilis Say)

Maryland, Virginia, and District of Columbia. F. C. Bishop (August 15):
Ticks decreased rapidly after the first week of Au.ust and infestations
on do-s had practically stopped after the 15th in Maryland, Virginia,
and the District of Columbia.

Mississippi. C. Lyle (Auf-ust 24): The Ancrican dor tick was collected on
cows by a correspondent at Purvis on July 31, who reportc- that ticks
are numerous on docs, hoefs, and cows in the southern part of Forrest


BROTiI DOG TICK (Rhipicephalus sanguinlus Latr.)
Maryland. F. C. Bishop (August 20): Several heavy infestations of dogs
and houses have been reported from Baltimore by some of the large
insect-exterminating companies in that city.


SCRE',T70idi (Cochiiomyia americana C. & P.)

United States. W. E. Dove (Aug-ust 24): In Florida andc in some of the
bordering counties of Georf-ia there was a low incidence, but the infes-
tations were well distributed. The rainfall and temnoeratures in these
wooded areas were favorable for infestations, but the small number of
untreated injuries present did not permit the insects to increase.
Cases wore reported principally from navels of :-u:r animals and from
tick bites, rather than from surgical ojorltions and such prerventable
injuries. From Au{ust 1 to 21 there were 2,475 cases reported fr-n
Florida, 42 from Georgia, 16 frnm Alabama, 13 from Louisiana, 4 from Miss-
issippi, and 9 from South Carolina. The reported cases included those
caused by na',Jots of bloc'flies, as well as from scrow7orms. The
primary screwworm occurred in most of the counties of Florida anmd in
tw-o localities in Geor:ia. S-rocimens obtained from Lowndes County on
July 29 and fr-m Effin: ham County on A'Twt 13 were identified as
C. americana. In South Carolina, Alaba., ississipi, and Louisiann C.
americana larvae were not found amon snocimonens collected from wounIs.
Durin.,. the past 3 weeks there wore 21,456 cases repo-rted from Texas,
149 from Arizona, 21 from California, 7,659 from Now 4exico, and 170
from Oklahoma. FollowinA' shearing there was an abrupt increase to
5,367 cases for 1 week. For the week ending A-ugust 21 there were 1,398
cases in this State. The cases reported from Texas include from 74
to 97 counties. In California.true screww'orms previously were reported
only from the southern Iart of the State. In August they were encountered
in Tulare County. This spread is attributed to the natural movement of
animals to the lower lands and to the beet fields and stubbles of clover.
At the stockyards in East St. Louis larvae of C. aeoricana were obtained
from injured animals in nine instances. The infestations were promptly
treated before the animals were reshiiedC. Three infestations were
fo-M,.. in calves from Fort northh Tex., which were consi'ned to the East.
Two infestations were found in the stockyards at Kansas City, Mo., and
were treated pr.:mFtly. Local infestations in Kansas were encountered
in ".'abuns:. and Greenwood Counties. In bcth of these counties efforts
were made to stamp out the introductions mn! there is -o evidence of
othor cases. All animals shipped to the Southeastern States arc beinF
examined promptly upon arrival. It is felt that reintroductirns of t.c
post will be prevented from causing serious trouble.

A BLO'JFLY (Paralucilia fulvips e acq.)

Arizona. C. C. Deonier (A'u-ast 26): A nuner of specimens have been taken
in fly traps in several localities in Arizona. Its occurrence in
Arizona ajlears to be a new locality record for this species, as here-
tofore it has booeen considered as bcin T restricted in the United States

to California. Present information on its distribution in Arizona
indicates that it is more abundant in the higher altitudes. Although
the species is primarily a carcass breeder, there is some evidence
that it is involved in causing myiasis in animals.

HORT FLY (Haematobia irritant L.)

South Carolina. W. E. Dove (August 21): A henvy infestation of horn flies
is present in certain localities on Johns Island, some animals having
approximately 3,000 flies feeding on their backs.
