Early in May grasshoppers started hatching in the Great Plains region and by 
the end of the month the poisoning campaign, which is being carried on in coopera- 
tion with the States, was well under way. 
Momon cricket outbreaks were recorded from Idaho, Montana, Wyoming, and Utah. 
Two outbreaks of the coulee cricket are occurring in. limited areas of Washington, 
one at Pasco, and the other near Wenatchee. 
Heavy flights of the beet webworm and alfalfa webworm were recorded about the 
middle of the month from North Dakota, south to Kansas, and westward to Colorado. 
The chinch bug outbreak has developed into what is probably. t he most serious 
outbreak in the past 50 years. The heavy drought over much of the chinch bug belt 
has prematurely dried the small grain and forced an earlier migration into the corn 
in some places. 
The pea aphid was destructive over a wide area extending from the Gulf norh- 
ward to Nebraska and Wyoming, 
The first adults of the codling moth were observed in the Hudson River Valley 
during the second week in May. They y/ere observed in Delaware and Virginia during 
the first week in May. In the West the first moths v/ere observed during the 
middle of April in Colorado and the Pacific Northwest, and in Kansas during the 
first week in May. The peak of emergence had practically passed in all sections by 
the end of May. 
One of the most severe outbreaks, of the grape leaf hopper ever recorded in the 
Napa and San Joaquin Valleys of California, was reported this year. 
Spring counts of Japanese beetle larvae indicate that this insect suffered no 
abnormal winter mortality during the severe winter of 1933-3*+. 
Single individuals of Brood VIII of the periodical cicada were recorded from 
Maryland in the vicinity of Washington, D. C. These records a„re well without the 
normal range of this brood, although previous records indicate that scattered in- 
dividuals have been found in this region. 
During the last week in April Mexican bean beetle adults were first observed 
in the eastern '/"Virginia trucking section, and during the middle of May in Maryland.
