With the harvesting of early small grains the grasshoppers have concentrated 
on fax, late small grains, alfalfa, and corn, and caused considerable losses in 
certain areas in the Northwest. During the month, over part of the territory, 
parasitic flies appeared to "be reducing the infestation. 
White grubs are generally abundant from New England to Kansas, with local 
serious damage. 
/Hessian fly surveys in the Middle Atlantic, East Central, and West Central 
States indicate that there win be heavy infestations on early planted wheat in 
western Maryland, Pennsylvania, Ohio, Indiana, Illinois, eastern Kansas, Mis- 
souri, and northeastern Nebraska. The situation is more threatening than it 
has been in many years over most of the Winter Wheat Belt. 
The chinch bug was reported doing considerable injury in the vicinity of 
La Crosse and along the Mississippi River in Pierce, Pepin, and Buffalo Coun- 
ties, Wisconsin, and Lake, Itasca, Hennepin, and Goodhue Counties, Minnesota, 
this region being very much north of the normal chinch bug belt. 
A severe outbreak of fall armyworm was reported by wire on September 2 
from northwestern Texas. 
The corn ear worn is generally prevalent throughout the greater part of 
the United States and, as usual, causing considerable damage to both sweet 
and field corn. In New Jersey it was observed attacking celery, an unusual 
food plant for this insect. 
The European corn borer was found early in the month in the suburbs of 
Racine, Wis. It appears that the infestation located last Aiogust in Sheboygan 
and Manitowoc Counties has been cleaned up. 
The cotton leaf worm has not yet appeared in the South Atlantic States, 
nor as far north as Arkansas. This is unusually late for the appearance of 
this insect. 
The codling moth is reported as from abundant to very abundant throughout 
the greater part of the country. In Illinois it has been more abundant than 
at any time during the last 10 years.
