j The dry v/eather that prevailed daring late May and well through June aggra-
vated the grasshopper situation. In general the sections of heavy emergence coin- cided with those indicated hy s\u-veys conducted last fall in certain States. ITo ! surveys were made in Wisconsin and Michigan and there the situation is much worse than was anticipated. Over 76,000 tons of poisoned bait purchased under a special appropriation has been alloted to the States, most of it going to generally in- fested territory.

^During June the j.ntensity of chinch bug damage increased greatly, the bugs leaving the smodl gTains an.: in certain sections damaging corn before barrier ‘ ma-terials oecame available. The luiusual v/eo-ther conditions caused the bugs to mature to the adult stage earlier thcji usuad. In the cocperahive campaign for chinch bug control carried on under special a.pproi)ria,t ion more than 1,250,000 gallons of creosote was allotted to Illinois, over 2,000,000 gallons to lov^a, ari. almost 2,000,000 gallons to Missoscri. Lesser amounts were a.llotted to other States in tile infested area. In some States the allotments from the speciad a.ppronria- tion were augmented by purchases made with funds supplied by PLEA.

OUTSTAIIDJITG EITTOMOLOGI CAL ELATIIRES IN CANADA DO JUIE '.'aS', 1934
Tlie grasshopxoer oufbroalc continues to Le of outstanding inportance throughout the gro,in~growing a,reas -of the three Praurie Provinces.' Hatching of the major species hegoii at the end of April in Alherta and early in May in Manitoho. and Sas- katchev/an, "being from 2 vreeks to 1 month earlier than in 1933 • Late in May and early in June, hatching wo, s -general and almost comi3lete in many sections, and crops were damaged severely over wide areas. .Unseasona'bly hot weather and retarded crop growth, due to lack of moisture, greatly increased the extent of the damage. In southeastern So.skatchewan important grasshopper migrations started, owing to lade i of food in the infested fields. General rains and cooler weather during the first half of J’one caused, further germination of seed, Letter crop growth, and lessened | activity of the insects, a.nd control camioaign efforts were much more effective imder these conditions. In Saskatchewan it is generally accej:)ted that in much of the i area of very severe infestation, where the soils a.re light or rcedium, there would ■' have Leen little or no cro]p survival after the drought had it not Leen for the con*- ! trol campaign.
The pale western cutworm began hatching early in the infested areas of Saskat- chewan and Alberta (by April 20 in southern Alberta), and by the m..iddle of May the infestation was .general omd damage had started. The daraage to croxDs by this spec- ; ies during May V7as excessive. The insects were checked, however, by rains and cool weather in June. In Manitoba , relatively little cutwwm damage has been noted.
In Eastern Camoxla local cutworm damiage, unusually severe in some sections, was re- ; ported in New Brnmswick, southerj.a Quebec, and Ontario.
Some losses from wireworms have occurred in certain localities in southern Al- berta. In Sasko-tchewam wireworms have done consideralole general damage to crops on summer -fallow, especially in medium soils. Seasonal conditions have been geneis- ally conducive to severe inj-ury by these insects.
Moderale flights of May or Jume beetles were noted in southern Quebec, eastern Ontario, and locally in southern Ontario during May. The beetles caused some damarge to the foliage of shade trees, raspberry, roses, aj.id other plants. White grubs are distinctly reduced in numbers in eastern Ont.ario, d.s compared with la.st year, but they are sufficierkly abundant to indicate an exce-ptionally large flight of beetles for 1935 > ^0 or more grubs per square yard of sod being common.
Extensive flights of beet webworm moths occurred in various localities in the ! Prairie Provinces during May. In Saskatchewan they were generally i:>resent through- ^ out at least the central and southern xoarts of the j)rovince. ;
The hop flea beetle is somewhat more alundant than average in localities in j'
southern Aloerto,, attacking radishes, rhubarb, and sugar beets, and is numerous in the Lower Eraser valley, British Columbia,, camsing local damo,ge to hops. Croj) doma,ge by the potolo flea beetle is severe in sections of Ontario, anul the cabbage flea, beetle is troublesome on Vancouver Island. i
The cabbage maggot is a serio’os x^sst on untrealed plants in southwestern Ontario. ! Eggs were noted in southern Quebec as more numerous than in 1933* Seed corn maggots I have damaged truck crops on Vancou'Syer Island,
Orchards in tne Annapolis Vo,lley, Nova Scotia, appear to be u,nusLi0lly free from insect pests. In the Olwanagan Valley, British Columbia, certain fruit pests a,re more prevalent tho,n' usual. Overwintering conditions in the Okanagan were very favorable for -hibernating insects. . f

The winter mortality of the codlint-; noth in several localities in soLithern O.itcn io va-ried approximately from 9 lo 52 percent. Adult moths hegcji to emerge at tile usual period in relation to the hlooninc of the trees. Trouble from this species is expected in apple-growing districts of British Columbia.
Aphids are remarkably scarce in Uova Scotian orchards, as a result of unu,sual autumn weodher followed by a severe ’winter.
In southern counties oi Ontario, where San Jose scale occ-ors, the winter mor- tality was found to range approxim.ately from 55 to S9 percent. The ninim.um winter temperabures recorded in the localities studied ranged from l4 to BfS de grees below zero. ^
Bait-pail records show that adults of the oriental fruit moth survived the cold Y/ffinter throughout the ITiagara district, Ontario. The cold, backwar^i surir- ■however, retarded the developm.ent of the species.

Wisconsin* E* L* Chambers (June 25): Probably the most serious epidemic of
grasshoppers ever experienced in Vifisconsip appeared this season, certain- ly the worst in the memory of ' the oldest residents. Thirty-five counties in the northern half of the State received both Stats and Federal aid in addition to large sums spent by the counties themselves so long as their | credit lasted* Arsenic sufficient to make up 9 >5^0 tons of the poison, in- cluding 2,000 tons of ready-mixed bran furnished by the Government, was | distributed* ’ j
Minnesota, A* G* Ruggles (June 26): Grasshoppers are very abundant in 40 ]
counties. Farmers are frantically calling for poison bait. The infesta- j tion is much worse than was expected. I
North Dakota, J* A. Munro (June I4): Hatching of the various economis species^ has continued up to the present. According to F* D* Butcher, Camnula •
pellucide Scud, is very abundant in the northern part of the State, while ; Melanoplus mexicanus Sauss* and M. bivlttstus Say are generally distributed,' The recent railfall over the hopper-infested area has been followed by heavy hatching*

Counties to Taylor, Fremont, and Page Counties, a total of 16 counties.
Over 250 tons of poisoned bait have been used in these counties,
Nebraska, M* H. Swenk (June 20): The grasshopper situation developed with .■ unexpected severity during, the second half of May and the early part of June* The heaviest early infestations were in the northeastern corner of the State, As the month advanced serious outbreaks developed across the central part of the State to the southwestern corner and northward into the panhandle. A total of l,83o tons of bait furnished by the ,
Federal Government has been distributed* j

CHINCH BUG (BlissTis leucopte rus Say)
New Hampshireo L. C. Glover (June 25): The chinch bug has been reported as doing serious injury to golf greens in West Hopklnton*
New York* E* P* Felt (June 22): Chinch bugs are present in considerable
numbers In a lawn at Scarboro\igh, This insect has caused serious damage on golf greens and lawns in this general area during the last few years*
Indiana* J. J, Davis (June 22): In seven northwestern counties, the chinch bug killed wheat and rye and began migrating into corn much earlier than \isual* The losses will be very severe* In the southwestern part of the State from Vincennes north and in the eastern and northeastern sec- tions the bugs are very abundant, but conditions are much more favorable for control by use of barriers. In these sections, although seriously affected by drought, the bugs are remaining in the wheat and rye until about harvest time. The government aid in furnishing creosote is much appreciated by the farmers. The chinch bug is about a week or 10 days ahead of normal. On May 16 we found the first hatching eggs. On. June 20, we found the first winged adults of the first generation at Lafayette, Forty-two counties are known to be infested to the extent that control measures are necessary and I feel certain that the final check-up vail find all counties north of a diagonal line from Kno^x County on the west to Randolph County on the east, to be infested to a noticeable degree#
Illinois, W, P. Flint (June 23): Chinch bugs have been extremely destruc- tive diiring the past month in nearly all parts of the State, omng to the drought. They left the small grain before it was cut. It is es- timated that more than 200,000 miles of barrier have been constructed within the State,
Michigan, R, Hutson (June 22): Chinch bugs are very abundant in Berrien County, at Galien and at New Buffalo,
Minnesota, A, G, Ruggles (June 26): Chinch bugs are very abundant in a fe?/ counties,
’Wisconsin, E, L. Chambers (June 25): Chinch bugs are beginning to appear in a few of our southern and western counties, but arc not yet doing serious damage,
lowa^ C, J. Drake (June 25): The infestati-oii is probably the worst in the history of Iowa, The bugs are doing damage in cC counties. In /\.0 southern co\.inties the bugs have destroyed from 75 5^ percent of the
small grain— -barley, oats, and wheat. In a few counties the county agents estimate that less than 2 percent of the,_small grain will be harvested or cut for forage. In many counties the farmers will do very
well to save one half of the corn crop. The noi’thmost records of migra- tion from anall grain to corn being from Story, Benton, Jones, and Jack- son Counties, Light infestations have been reported in a few counties in the northern p8.rt of the State, Over 2,000,000 gallons of Creosote coal tar have been used this summer. The County Agent of Monroe County
134
stated that the farmers were very much concerned abaat pasturing cattle in small grain fields heavily infested. In one instance a farmer re- ported the death of a cow from feeding upon small, grain plants covered with the bugs. A post-mortem examination of the cow showed thousands of chinch bugs in the intestinal tract. The veterinarian diagnosed the cause of the death as the result of toxines from the bugs.
Missouri. L. Easeman (June 25): VVe are rapidly drawing to a close the
greatest active campaign of control against this pest that Missairi has ever been called on to wage* The Federal cooperation came just in time to largely save the day. About 1,. '250, 000 gallons of barrier oil have been furnished by the Federal department, saving a good many millions of bushels of corn. Bugs will continue to migrate until the first of July in some counties, but the available supply of oil will about take care of our needs. About 70 counties have been heavily infested and 20 or 30 of these most seriously*
Nebraska. M. H. Swenk (June 20); Late in May and early in June a very
severe infestation of the chinch bug developed in southeastern Nebraska, extending north into Butler, Saunders, and Sarpy Counties. Less severe infestations involving serious crop destruction occurred in the four counties immediately west of this area, A separate infestation of less severity developed in south central Nebraska, The migration started fully 10 days earlier than the earliest beginning of a chinch bug migra- tion previously recorded (June 12, I933)) nearly 3 weeks ahead of the average beginning of migration (June 21).
Kansas, H* R, Bryson (June 26); Chinch bugs began migrating at Bianhattan on June 1 and reached the peak of migration on June 14. They are very abundant in the eastern two fifths of the State, Extensive use was made of dust and creosote barriers. The adults were flying to other fields on June ig and 20.
CORN ROOT APHID (Anuraphis maidi-radicis Forbes)
Iowa, C, J, Drake (June 25): The corn root aphid has been reported from a large number of counties in Iowa this spring. In several instances the fields are so heavily infested and badly injured that the farmers have given up trying to grow corn and are replanting the fields to soybeans*
In Story County the aphid was found in large numbers feeding on the roots of melon plants, an unusual record for this insect,
CORN EAR Y/ORM (Heliothis obsoleta Fab, )
North Carolina, R, Vif, Leiby (June 14) J The corn ear worm is either more de- structive than usual on commercially grown corn in the eastern part of the State or there is more than the usual interest in preventing damage.
South Carolina, VY, C. Nettles (June 23): The corn ear v;orm is damaging
young tomatoes at Clemson College, In the eastern section it has damaged seed heads of flax in experimental plantings,
Iowa, C. J, Drake (June 25): Many farmers, especially growers of sweet corn,
135
are asking about the corn ear worm. Apparentlj'- the insect is v/idely distributed in the State and may do a considerable amount of damage#
Kansas. H. R. Bryson (June 2b): The corn ear worm is very abundant. A
considerable amount of damage has been done to the curl of the corn plants. The insect also has been reported injuring tomoto fruit at Canton and Wichita*.

Georgia# 0. I. Srnpp (June I3 ) J This insect has destroyed the corn on about 20 acres of very fertile bottomi land at Haddock#
Illinois# W# P# Flint (June 23): There has been a very widespread and ex- tremely destructive outbreak of the rough-necked cornstalk beetle in the southern third of the State#
C. L. Metcalf (June 20); The sugarcane beetle has been reported as very destructive to corn in Hamilton County. The injured field of corn and soybeans adjoins 160 acres of bottom land, most of Y/hich is in cul- tivation this year for the first time in 4 years#
Mississippi# J# M» Langston (June 22): On June 3 ^ groY/er at Dorsey, Itawamba County, sent adults to this office, with a report that they had severely injured young corn# Complaints of injury v/ere also re- ceived from Rockport, Copiah Goilnty, during tLe latter part of May*
FLEA BEETLES (Halticinae)
Indiana* J. J. Davis (June 22): Flea beetles are the second most important pest of field crops in Indiana# The pale-striped flea beetle ( Systena taeniata blanda Melsh# ) is the predominating species attacking corn and by far more abundant than I have ever known it to be# Specific records include; At Connersville, in one field, 2l6 tomato plants destroyed in one night; at Goshen, 30 "to 4^ percent of corn taken in some fields, also attacking soybeans, Canada thistle, morning glory, and milkweed; at Fort Wayne, destroying com and truck crops; at Hamilton, a iG-acre field of corn was destroyed and other cornfields were seriously damaged; a serious pest in corn fields at South Bend, Rochester, Albian, and Topeko# All of these infestations are in the northern half of the State.
Striped flea beetles (species unknown) were reported damaging corn, beans, beets, and potatoes at Aurora, Avilla, and Danville on June 1 to b, and the black potato flea beetle was reported from Aurora, Avilla, and North Judson on June 1, 6, and I5 , respectively#
Michigan, R« Hutson (June 12): Vife are ha.ving trouble with the pale-striped fl^ beetle on field corn in the southern tier of counties#' (June 1^): The pale-striped flea beetle was reported today from several points in the northern half of the lower peninsula#
Wisconsin# E. L» Chambers (June 18): The pale-striped flea beetle has been unusually abundant this month throughout the south central portion of the State, destroying large acreages of corn and potatoes.

SUGARCANE
SUGARCANE BEETLE (Euetheola rugiceps Lee . )
Louisiana, J, W. Ingram, W, A, Douglas, and E, K, Bynum (June): Beetle in« jury in the sugarcane section was practically over the last of June, The heaviest injury occurred during May, Loss from injury to sugarcane was 40 to 50 percent less than in the 3 years. This decrease v/as due partly to the growing of varieties giving a, larger nuiTiber of plants per acre and having greater recovery ability on land that is subject to heavy beetle in- jury, and in part to increased rainfall at the time of injury, which stimu- lated growth and increased recovery.

Georgia, 0, I. Snapp (May 28): The first pupation of the season took place today at Fort Valley, The cold rainy weather in May retarded the develop ment of the curculio in the soil, and as a result it is doubtful whether there will be a second brood. Usually only one generation occurs in this latitude when pupation is as late as the last of May, Cool weather continues and will undoubtedly prolong the pupation period, (June G):
The first transformation to adult beetles in soil cells was recorded today, (J\ine 13^): The first new beetles of the season emerged from the soil today. This is I7 days later than the first emergence last year
142
