INSECT PEST SURVEY BULLETIN

OUTSTANDING ENTOMOLOGICAL FEATURES IN THE UNITED STATES FOR JUNE, 1923. 
The past month has been one of unusual insect abundance throughout the 
greater part of the country. 
Cutworms of several species attacking practically all field: and truck crops 
have been reported from the entire northern part of the country, reports of serious 
injury coming from Massachusetts, New York, Michigan, Iowa, South Dakota, and Idaho, 
and unusual wireworm injury to both cereals and truck has been reported from Ohio, 
Indiana, and Illinois in the East-Central States, and from Montana, Idaho, and 
Washington in the Northwest. 
Serious grasshopper outbreaks have been very general over the upper 
Mississippi Valley, through the Rocky Mountain region, and along the Pacific Coast. 
Reports cf outbreaks have been received from Wisconsin, North Dakota, Nebraska, 
Kansas, Texas, Wyoming, Utah, Oregon, and northern California. In the Klamath Lake 
region of California poisoned bran bait was being distributed at the rate of 10,000 
pounds daily. 
Heavy flights of June beetles occurred in parts of New York, Illinois, 
Wisconsin, and South Dakota; on Long Island, and in parts of southeastern South 
Dakota the heaviest flights that have been observed in years were recorded this year. 
By the middle of the month the chinch bug was migrating from small grain to 
corn in Indiana. The situation relative to this insect, however, looks much more 
favorable than earlier in the season over the greater part of the chinch bug region. 
Egg laying was generally delayed by the backward season and heavy rains associated 
with the fungus disease and egg parasite in Illinois, Nebraska, Kansas, and South 
Dakota have materially reduced the infestations . 
Hessian fly injury will be severe in Iowa and Nebraska owing to the heavy 
spring brood of flies and wheat is damaged from 2 to 25 per cent in parts of Illinois 
and Missouri by the jointworm. In some fields in Greene County, Missouri, 12 per 
cent of the straw is down owing to the feeding of the latter pest. 
The boll weevil is emerging in fairly large numbers throughout the Cotton 
Beltj indications have already been reported of heavy broods in Georgia and Texas. 
A suggestion is made that dusting for the boll weevil tends to increase damage by 
cotton aphids by killing lady-beetles which feed upon this pest. 
The pale striped flea-beetle is doing unusual damage to corn and truck crops, 
particularly to beans, in Indiana, Illinois, and Virginia. 
The seed-corn maggot is again appearing in unusual numbers in parts of New 
York, Illinois, and Tennessee. In the last State the outbreak was decidedly more 
serious on land where fresh tankage fertilizer had been used. A similar association 
of this pest with organic fertilizers was noted in 1921, when an unusual outbreak of 
this pest occurred along the Atlantic Coast.
