.THE MORE IMPORTANT RECORDS FOR JULY, 1933

In addition to reports of generally severe grasshopper infestation occurring in the Great Plains we have reports of very heavy infestation in the upper
-and lower peninsulas of Michigan, the northeastern one third of Wisconsin and two outbreaks in California, one in the Imperial Valley and the other in the San Francisco Bay district. The infest,,tion in the Mississippi Delta continued severe during July and several carloads of bait were distributed in that district. In northeastern Nebraska 18 carloads were used. We'do not have definite figures for the quantity of bait used in the D-:otas and Minnesota where the .eaviest control campaign is urdo way.

Serious chinch-bug 6utbreaks arc under way in eastern Kcnses, northern
Missouri, southern Iowa, central Illinois and Indiana, southern ichigan, and western Ohio. In Illinois and Ohio infestations are reported as nore severe than they have been in -ers.

The green June beetle is unusually prevalent this year in Ohio, Missouri, and Tcr-nessee.

Very heavy infestations of the Colorado potato beetle are reported from New ~g.jland, Wisconsin, Minnesota, North D-kota, eastern Tennessee, and eastern Wyoming. In the West these beet les !re decidedly more numerous th.n they have been before in the Yacima Valley of Washinton en an infestation covering a few square miles near the Weber-Davis County line has been discovered in northern Utah.

Very heawjvy infestations of the potato leah:pper "'ith the resulting hopper-burn injuryaje reported from the Miidl Atlatic States from Connecticut to Virginia and westward to Iowa and Hinnesota.

The potato tuber worm has been found in a number nf potato fields in
central Iowa. This is the first record we have for the State of Io-a and the first record of its being established in potatoes in the Central States.

The Mexican bean beetle was found far to the northwest of its known distribution in the St. Paul Minneapolis district of Minnesota. This is believed to be a corr.ercial jump and exteminationi is being attempted.

The gladiolus thrips was reported for the first time during July in eastern Iowa and Delaware.

GE:TERAL FEEDERS

GRASSEOPP S (Acrididae)

Michigan. Ray Rutson (July 22): Grasshoppers are very abundant in the upper
peninsula and the northern part of the lower peninsula.

Wisconsin. E. L. Chambers (July 24): Very serious damage has occurred in about
30 counties of northern Wisconsin, principally the northeastern third. Nearly 100 tons of white arsenic was used in baits in addition to several carloads of molasses and many carloads of bran.

Minnesota. A. G. Riugles (July 15): We are controlling grasshoppers remarkably
well in spite of ideal weather for the hoppers. The prediction made last
December was 99 per cent correct.

North Dakota. J. A. Munro (July 22): Reports indicate that various species of
grasshoppers are very abundant over most of the area previously reported as
infested. Where control was begin early, successful poisoning campaigns
have resulted. Egs are now being deposited by Melanoplus bivittatus Say,
I1. mexicanus Sauss., and Camnula pellucida Scudd.
R. L. 01son (July 17): Strong grasshopper flights high in the air were
notel on July 9, in Bowman County, all going southeastward.

M-ississippi. C. Lyle (July 21): Several scattered outbreaks of grasshoppers,
chiefly M. differentialis Thos., in the Mississippi Delta were reported during the past month. Serious damage continued on several thousand acres of
corn, soybeans, and cotton at Parchrman until the application of several carloads of poisoned bait save control.

Nebraskca. R. Roberts (July 20): Grasshoppers have been very abundant in the
northeastern part e the State. A state-aided control campaign has been in progress for over a month, 18 carloads of poisoned bran mash have been
distributed, and ood 'ills hive boon re-orted.1 Reports have also been
received from Douglas, Salino, and _arlan Counties.

Wyoming. C. L. Corkins (July 21): Grasshoppers are very abundar.t. A severe
outbreak developed iur!ng earl- July in Crook County. The valleys are infested with M. bivittatus, a:d the grazing lands in the hills have a
mixed infestation of any species, which h are no, migrating to the valle-s.
Certain sections of Sheridani Courty have serious troubles. Minor outbreaks
have developed in Fremont, Johnson, a.' 7eston Coun.ties.

Utah. G. F. Knowlton (July 11): M. bivittatus is damari:ng s-uar beets, strawbcrry7 plants, and blac::-cap raspberries at Hooptr. Grpsshoprers are domain
alfalfa and grain on the ranches in ull Valley, ~articularly .t losepa.
Large numbers of 1. eexicanus are becomin- adult in man- parts of Toccle
County and are causing serious damage to crops at Grantsville. (July 21): Grasshoppers completely dest-'oved a 3-acro sugar-beet patch, then advanced
upon wheat and barley during Jane, in the low area west of Provo.

California. A. 7. Michelbachelor (July 20): In at least one area near Tracy the
di'cretial grasshopper, _. diffcrentialis, is rather abundant. I have




-189

watched the development, and at the present time a large number have reached
the adult stage.
Evening Star, Washington, D. C. (July 26): The worst grasshopper plague in
17 years is being experienced by Imperial Valley. Desperate in their efforts
to destroy the pest, farmers plan to import pheasants in the hope that the
birds will eat the hoppers before the second cro_ Apito'uts wings. GfapeTruit
have been devoured by the thousands.

WHITE GRUBS (Phyllophaga spp.)

Illinois. W. P. Flint (July 22): Serious damage from white grubs is beginning
to show in cornfields in northern Illinois. .

Wisconsin. E. L. Chambers (July 24): Serious losses from white grubs are being
reported by nursery inspectors and other field men in some of the southern
counties.

Iowa. H. 7. Jaques (July 24):, The area of.serious infestation in northwestern
Iowa seems to be enlarging to the east. The ~bandtrce in other parts of the
State seems less than normal for this brood.

Missouri. I. Haseman (July 25): Only the -sual number of white grubs at this
season in central issouri; though in southern issouri one orchardist
reported defoliations of apple recently.

GREI JUNE BEETLE (Cotinis nitida L.)

Ohio. N. F. Howard (July 10): Adults were present in large numbers on sweet
corn and cucumbers at Marietta on July 8. They.were so numerous as to
resemble a swarm of large bumble beesp.

the Cumberland Plateau section and Knox County.

JAPA:TESE BEETLE (Popillia japonica Newm.)

General. C. T. Hadley (July 24): In the older infested territory the Japanese
beetle is less abundart than last year. This is especially true in the
Philadelphia suburban region. In the more recently infested territory the
beetle is abundant and foodinT extensively on the usual preferred food plants.
In addition to those plants, the beetle is this year feeding on alfalfa,
clover, and beans. It has also been causing, for the first time, considerable
injury in nursery plantings to evergreens, especially Cryptomaria and juniper,
as well as to rhododendrons and azaleas. The insect has also been reported as feeding extensively on a cultivated banana plant in a yard at Moorestown.
Feeding on waxmyrtle (irrica carolinensis) has been extensive at the Wildwood Golf Course at Burleigh, ,T. J.

New Jersey. Headlee and Burdette (July 24): The Japanese beetle is very abundant.

common all over our neighborhood now,

ASIATIC GARDXN BETLE (Autoserica castanea Arrovw)

New York. C. H. Hadley (July 24): This beetle is more abundant on Long.Island
this year than it was in 1932. Reports of injury have been received from small
property owners as well as from large estates in the infested region. Extensive d&nage to much ornamental plants as chri'santhemum3, asters, orchids, and
dahlias is common, and in gardens the feeding is heavy', on cabbage,, eggplant,
and peppers.

COMMON RED SPIDER (Tetranychus telarius L.)

Georgia. 0. I. Snapp (July 12):, Weather has been dry and hot and red spiders
are more abundant than usual at Marslallville, causing considerable daTmage.to
yard plants.

CEREAL AND F 0 RAGE- CR 0 P INSECTS

CORN

CHINCH BUG (Blissus leucopterus Say)

northeastern United States. E. P. Felt (July 27): Infestations in lawns have
come to my notice recently from Philadelphia, Pa., northern New Jersey,
southern ow York, and southern Connecticut.

Pennsylvania. J. S. Pinckney (July 22): An outbreak was reported on corn near
Goodyear, Cumberland County.

Ohio. T. H. Parks (July 13): We are having the worst infestation in many years.
May was rainy; June was dry. Bugs have destroyed many plantings of barley in Madison, Union, and Delaware Counties. They began moving out of barley and wheat fields the last week of June and were still moving July 13. One
gas company has already sold 5,000 gallons of tar for making barriers. Madison County shipped in several carloads of tar. Miles of tar lines have been made and as many.dust barriers. A few fields of corn were ruined before the
farmers were aware of the bugs. The area affected is mainly in thc westcentral counties. Reports of damage have reached us from 14 counties.

Indiana. J. J. Davis (July 25): The chinch bug has been an outstanding problem
in many sections of the State. There qre t-o centers of infestation. One in
the northwestern corner includes Newton, Benton, Lake, and LaPorte Counties.
The other is in the northeastern part of Indiana and includes the counties of
Jay, Adams, Allen, Steuben, Wells, Elkhart, and Blockford. Reports of infestations in small grain or migrations from small grain to corn have been reported from the above areas throughout the month. June 29 the bugs were moving from barley and oats into corn at Fowler. Apparently barley is the
source of the heaviest infestations.

Illinois. W. P. Flint (July 22): during the past month the chinch bug has been
the outstanding crop pest in the State. Spotted heavy damage has occurred
from Randolph, Montgomery, Clay, and Jasper Counties on the south to Rock
Island, Henry, Lee, DeKalb, Kane, and Cook Counties on the north. The first
brood has now matured snd a general:flight has taken place over the cornfields.
The weather is do dry that the second brood will probably cause serious
damage throughout the heart of the Illinois corn belt. From present indicationE
it is possible that the bugs may cause aloss of 25 per cent of the corn crop
in this area.

Michigan. P. H. Pettit (July 12): I have just received word. that chinch bugs
have destroyed many fields of corn, barley, and some oats at the town of
Seneca, Lena:woe County. This is the first serious outbreak that 'To haive had
in several years.
Ray Eutson (July 22): There are several outbreaks in Berrien County. From
time to time we have had trouble in others of the southern counties, but this







is the- first time the bug has caused any damage in Berrien.

Minnesota. A. G. Rugglcs (July 15): The chinch bug is very a:bund ant in Gooduae,
Washington, Muillo Lacs, Anoka, and Wabasha Counties.

Iowa. C. J. Driako (July 27): Chinch bug injury has been very severe in the two
southern tiers of counties in Iowa. Losses are quite heavy, especially from
Taylor and Union Counties east to Leo and Louisa Counties. In a fc' cases
some injury was done in the third tier of counties. At the present time the adults of the first generation are depositing their eggs and the young of the
second generation are beginning to appear in considerable numbers.

Missouri. L. Hasean (July 25): Infestation has been general and in some places
very heavy over the northern half of the State. The bugs are most abundant
north of the Missouri River a-nd near the Iowa line.

Tennessee. G. 1. Bentley (July 22): The clhinch bug is abundant around Manchester
in Coffee County where it is d.maging corn.

Nebraska. R. Roberts (July 20): UTxnerous reports were received from Richardson,
Saline, Gosper, Lancaster, and Furnes Counties.

Kans,,.s. H. R. Bryson (July 25): Observations made n a trip through Morris,
Riley, Geary,, M1arion, Dicki'.son, Butler, Sedgwick, and Chase Counties revealed
chinch bugs being quite destructive to corn anud sorghums and adjoining fields
of small grains. Dry weather *was favorable to the bugs in their attack on the
row crops. Reports of injury have also been received from Wabaunsee, Cloud,
and Mizrni C ountics.
