THE MORE IMPORTANT RECORDS EOR JULY 
By the third week in the month general control operations for the control of 
the long-winged grasshopper was completed in Colorado and Oklahoma., the work in 
New Mexico and Texas having "been completed about a week earlier. Clean-up work, 
however, on egg-laying concentration areas will ho continued throughout the season. 
Control was so successful as to prevent important flights. Control work in the 
northern Great Plains is practically completed. The populations are shifting from 
harvested fields and considerable damage is being done to fall crops. Losses from 
flights, however, do not compare with those of last season. 
A colony of European earwig discovered at New Haven, Conn., last' yea.r became 
apparently thoroughly established. In the Pacific Northwest this insect is much 
more numerous than last year. 
Heavy populations of June beetles are reported from the northern part of the 
Eastern Shore of Maryland and from southern Virginia. 
The Japanese beetle is becoming more seriously abundant in the rural areas 
of Connecticut and this year was reported for the first time attacking shade-grown 
tobacco. Southern New York, northern Maryland, and the Eastern Shores of Maryland 
and Virginia also report considerable defoliation of ornamental shrubbery and 
trees and spotted damage to agricultural crops. 
The beet webworm was reported as doing some damage in North Dakota and 
Nebraska, with heavy flights of moths early in the month. The sugar beet crop 
in Utah County, Utah, is much more heavily infested than in previous seasons. 
The chinch bug caused local damage in several counties in Indiana, in local 
areas in Illinois, and in southern Michigan and Wisconsin. A potential outbreak 
in Iowa was relieved by timely rain. Less extensive infestations were reported 
from Missouri and Nebraska. 
In the Mississippi Valley as far northward as Wisconsin, Minnesota, and South 
Dakota corn ear worm seems to be abnormally abundant, 
European corn borer seriously abundant in Connecticut, southeastern New York, 
and central New Jersey. The . insect is apparently increasing in eastern Indiana 
and a survey conducted late in July showed 7 infested counties in Wisconsin, 
The most general outbreak of the fall arnyworm reported in several years was 
occurring in Mississippi, A minor infestation was reported from Georgia.
