THE MORE IMPORTANT RECORDS FOR AUGUST 
Grasshoppers continued to be the major entomological feature in the 
Plains and Rocky Mountain States. Second-brood Melanoplus mexicanus Sauss. 
are appearing generally in Missouri, Nebraska, and the adjoining States. 
Egg laying of the Mormon cricket is well advanced or completed in the 
Great Basin. 
The Gulf wireworm was found 112 miles north of the Gulf coast in Miss- 
issippi during the month while the sugar beet wireworm was more abundant in 
Ventura County, Calif. , than ever before recorded. 
A survey indicates that the white-fringed beetle is lightly infesting 
about a thousand acres in Jones County, Miss. The -infested area in Walton 
County, Fla. , has been found to be somewhat wider than heretofore known. 
The variegated cutworm did considerable damage to tomatoes, celery, and 
other truck crops in Indiana and Michigan. 
An outbreak of the garden webworm occurred early in the month in eastern 
Nebraska, principal damage being done to alfalfa. A very heavy flight of the 
moths was observed late in the 'month in Oklahoma. 
The hessian fly survey carried on in the West Central States indicates 
that the fly is at the lowest population level ever recorded. 
Heavy losses of late sweet corn and tomatoes by the corn ear worm were 
reported in the Middle Atlantic and East Central States. 
The European corn borer was reported in destructive numbers in Connecticut, 
Vermont, and New Jersey and on the Eastern Shore of Virginia. 
A very heavy population of the potato leafhopper was reported from the 
East Central States, damaging alfalfa and potatoes. Infestation on potato 
was so heavy in Wisconsin that practically all fields were brown before the 
third week of the month. 
Peak flights of adult codling moths were reported in the upper Hudson 
River Valley on August 3; in Delaware on August 11; in Knox County, Ind. , on 
-335-
