THE MORE IMPORTANT RECORDS FOR AUGUST 1935
During the latter part of July and the early part of August very heavy outbreaks of cutworms were reported from Michigan and MIaine.
Serious damage was occasioned by the fall armyworm in the South Atlantic Stetes and the Gulf region.
The green June beetle was reported from Delaware and Georgia, in the East Central States, and in New Mexico.
The green sti iLk bug damaged a wide variety of plants in 'New Mexico and California.
Common red spiders were quite generally reported from the Gulf northward to Nebraska and also on the Pacific Coast.
Heavy hessian fly populations are present over a wide area from southeastern Kansas to central Pennsylvania.
In the East Central States the weather was adverse to the development of large populations of chinch bugs. In the West Central and the southern part of the North Central States the weather has been very favorable to this insect.
The report in the last number of this bulletin of the finding of alfalfa weevil in Mendocino County, Calif., was a mistake.
Plum curculios of the second brood were reported as very scarce in the Middle Atlantic and South Atlantic States.
A further report on the cherry scale in California, in which State it was found for the first time last year, appears in this number of the bulletin.
Blister beetles were quite generally prevalent and are doing considerable damage over the greater part of the country east of the Rockies.

Reports of thie occurrence of the black widowido weevryfe
quently received during the month in the South Atlantic, East Central, and Tiorth Central States. This snoider was also re' ortod from the Great Basin.
U-o to the end of July four cases of Roc1qr M~ountain s:?otted fever were re-,ortcC'. frora the Sta,,te of Iowa.
THE MORE IMPORTANT ENTOMOLOGICAL FEATTLRES I'l CAITADA FOR JULY AlD AUGUST 1935
Cool, wet weather in June and heevy rains in early July in Manitoba and Saskatchewan resulted in irregular and retarded hatching and slow development of grasshoppers, and in reduced crop) damage. Organized control efforts, involving the widespread use of poisoned brit, were continued in the infested areas throughout the Western Provinces. In Manitoba the "issease Em-usa Frylli was re-orted to be causing high mortality mong the roadside and two-striped grasshop-ers, and had appeared in areas in Saskatchewan where rains had been frequent. Crop damage has been comparatively igah in wanitobai 1..... light in Manitoba and Sas:katchewan, except in the south-central part and local areas of the latter Province. Losses were occurring in some sections
of southern Alberta, where they were accentuated by drought. Winged adults were becoming conspicuous in parts of the Prairie Provinces by the end of July. No extensive migrations have been reported. Egg laying was general by mid-August, and in the Red River Valley, Manitoba, adults were abundant enough to deposit sufficient eggs to create a menace in 1l96. Central Manitoba was comparatively free of the insects. In British Columbia, grasshoppers were reported to be increasing on the ranges in the Ka-nloops area, and in the Cariboo district.
The outbreak of the pale western cutworm was fairly widespread in Saskatchewan and Alberta, but severe damage occurreC. in only a few areas. The largest area of general and severe infestation was in the ShackletonLeader-Fox Valley area of Saskatchewan, extending for a short distance into Alberta. Severe local infestations also occurred in several areas of the drier districts of Alberta, centering on Lethbridge. Heavy rainfall in May and June in many areas has eliminated the -pale western cutworn as an economic pest for 1936. Over a large part of the two Provinces, however, where rainfall was only sufficient to hold the insects in check, damage in l36 may be expected to be about the same as this season.
The red-backed cutworn also caused crop damage locally in the Prairie Provinces.
Cutworms of several species were exceptionally abundant throughout a large part of the cultivated areas of the Provinces of eastern Canada, and in many places caused unusually severe damage to various field and garden crops. An outbreak of the snootted cutworm in southwestern Onterio resulted in the destruction of a large part of the sweetclover seed crop.
Second-year white grubs are prevalent in timothy and hoed crope in southern Quebec, and have caused destruction locally to sugar beets and strawberry plants in southern Ontario.
As during the last several seasons, blister beetles of several species are widespread in the Prairie Provinces, inflicting damage chiefly- to leguminous shrubs and field and garden plants. A reduction in their numbers as compared with 1934 has been recorded in certain areas.

Heavyr flights of months of the sodl webworm (Crambus trisectus Walk.) occi..rred throughout southern Ointrio. The larvae of" this sp-ecies had attacked pasture fields, cor-n, tobacco, and_ other cro--s. There was also general and widespread injur, to lawns and golf courses bXy sod viebWorms in this c-ection.
An unusually severe outbreak- of the pea aphid developed fn sections of Zuebec and Ontario. Dariage was less serious thU -an- was ant-Ici-pated, probably as a result of thie onset of weather conditions unfavourable to th-,e apIi id s .
The Eurol~ean earwig appeared' in exceedingly large numbers in. the

Injury by the codlin- moth in-, the iliaga'ra dIietrict is much less_ severe than last year. The s-pecies is in evidence in some sections of th'-e Anna~jolis Valler, N~ova Scotia.
First-generation adults of thie oriental fruit moth were found in all distr-,icts of the N~iagara Peninsula, but were in smaller numbers than in former years. The s-pecies is much less abundfant th-an In 1031' and injury is slight so far.

Adults of the grape leafh-opper came through the winter in immense
numbers in many vineyards in thie Niagara district. I nj ury by these insects is severe in uns-orayed and. poorly sprayed vineyards.
Heavy infestations of the fall webuorm were reported locally in lova Scotia, Quebec, and southern Ontario. A more gener-al outbreak occurr'e in Lnitoba, and severe infestations occurred in various localities in Sask-tchcwan and Alberta.
Adults of the European spruce sawfly, in flight during the first week of June in central New Brunswick, wore several times more numerous than in 1934!. In the Gaspe Peninsula, Quebec, the infestation continues to be heavy and an increase in mortality of the trees is inevitable. The infestation: has increased considerably in Kamouraska County, Quebec, and some of the trees are dying. The species has been found in Cumberland and Pictou Counties, Nova Scotia, but does not appear to be present yet in other parts of that Province.
The yellow-headed spruce sawfly caused extensive defoliation of spruce in northernSaskatchewan and northern Alberta. Indications are that it will eventually become generally distributed throughout the southern portion of these Provinces.
A severe outbreak of the mountain pine bark beetle, affectin. lodgepole pine, has been found in the Kootenay National ark, British Columbia It is believed that the outbreak has been spreading during the past 5 years.
Heavy infestations of the satin moth have been re-orted in a number of localities in Prince Edward Island; the AmLerst and Springhill districts in Nova Scotia; and in Sackville, New _runsvick. The moths were emerging on July 13 in Nova Scotia. The species is reported to be comparatively scarce over the greater part of the area of infestr tion i-r 3ritish Columbia.
Reports of increased abundance of mosquitoes,as compared with previous years, have been received from New Brunswick, southern Quebec, sections of Ontario, and the Western Provinces. They were noted as extremely abundant and annoying throughout the three Prairie Provinces, and were reported to be an exceptionally severe nest in the Kamloonos area and the Cariboo district of British Columbia.

Michigan. R. Hutson (August 15): Beginning about July 2j we had the
worst infestation of cutworms on all sorts of crops thAt we have
ever had. The principal species concerned was the variegated cutvrorm (Lrcoohotia margaritosa saucia Hbn.), accompanied, in many instances, by the true arry":orm.n (Cirphis unipuncta Haw.). Oats had been lodged and in these oat fields large populations o0f cutworms accumulated and migrated with the arnmyw7orm. This outbreak : is unusual in that usually by the kth of July all the cutworm and armyworm infestations have been cleaned up through natural causes.

an average of 105 eggs per 100 terminals.
New Mexico. D. M. McEachern (August 17): There is a light infestation in the
Pecos Valley of New Mexico. Corn and cotton appear to be the only plants
on which the worm is flooding.
Arizona. T. P. Cassidy (August 17): Causing some damage about 25 miles northwest of Tucson. The major damage is being caused to young bolls. Most of
the larvac are about full grown.

Arizona. T. P. Cassidy (August 10): An intensive inspection was made in
experimental cotton grown 25 miles southwest of Tucson on August S.
Six species of hemipterous insects were found. The relative abundance
of C. uhlori and all other species was about 10 to 1. The shedding was confined almost entirely to young bolls. Examinations made of a number of plants showed that from 70 to 100 percent of the bolls had been injured by hemipterous insects. This is the heaviest injury of this kind
over roted here. C. uhleri seems to have migrated into the field from

part of Aroostoo_, County, about 30 miles south of Fort Kent, an. in
Somerset County, north of i:oosehead Lak:e. T ier :ampshire light infest-tions were found at First Connecticut La:e and south as far as
Campton. It seems to be generally distributed all over the white
Mountains. In Vermont infestations were founC. from Iewport to Stowe.
Although the infestations in each case have been re-ported light, the sawfly is present in sufficient numbers and is distributed over such a wide area as to cause considerable alarm. The larvae were found
feeding on both white and red spruce.
