OUTSTANDING ENTOMOLOGICAL FEATURES FOR SEPTEMBER, 1922 
There is practically no change in the Hessian fly situation since 
the last report* Observations in Iowa indicate that the heaviest 
emergence in that State is taking place in the south-central counties* 
The Bureau of Entomology Survey shows a decided decrease in the 
percentage infestation in Maryland, Delaware, and s out haras tern 
Pennsylvania, while in the Susquehanna Valley of the last State there 
is a marked increase* 
Favorable weather in the east-central States has resulted in a 
decided increase in the number of chinch bugs of the second generation 
to reach maturity* In all probability an uraaaual number of adults 
will go into hibernation in this region* 
The corn earworm was decidedly less serious throughout the northern 
part of its range than was the case last year* 
The true armyworm was not serious over most of its rangg* In Illinois 
it was less numerous than has been the case for many years* A few 
isolated and unimportant outbreaks developed in the west-central States* 
The apple and thorn skeletonizer continues to increase in intensity 
of inf3statiom and in its range in New York and Connecticut* 
The shot-hole borer is attracting considerable attention in the 
middle Atlantic and east-central States, where it is reported as attacking 
apparently otherwise healthy trees* 
The potato leaf hopper associated with hopperburn has been very 
serious in Wisconsin and western New York* 
The Mexican bean beetle is consistently spreading northward; six 
new counties in Tennessee and one in Kentucky are reported infested 
during this month. Very little spread has been recorded southward from 
the original Alabama infestation. 
The belted cucumber beetle is rapidly becoming a major crop pest 
in the lower Mississippi Valley* 
The boll-weevil situation remains practically as in the last 
report* Boll damage is now reported as serious in many places throughout 
the cotton belt* 
The bollworm is reported as serious in central Georgia, western 
Arkansas, and several places in Louisiana*
