OUTSTANDING ENTOMOLOGICAL FEATURES 
FOR THE WINTER OF 1921-22 
AND THE SPRING OF 1922 UP TO APRIL 1. 
The Hessian fly situation has not been reported as at all 
serious in any of the important wheat -growing sections this 
spring. 
Over the region infested by the chinch bug the winter has 
been comparatively rnild and observations in Illinois indicate 
that the winter mortality of this pest was extremely low. 
The adults became active in southern Illinois during the middle 
of March. Investigations made in Ohio indicate that this pest 
normally hibernates in farm wood lots and not in the weeds and 
grass along the fence rows as was formerly believed to be the 
case. 
An interesting phase of the green-bug situation has developed 
this spring. Surveys carried on by the Bureau of Entomology 
indicate that there is practically no infestation of the green 
bug in northern Texas this year, the severe droughts of last 
summer having prevented the growth of volunteer wheat. In 
northern Oklahoma and eastern Kansas, however, there seems to 
be a sufficient green-bug infestation to start an outbreak in 
these regions, if weather conditions are favorable. This seems 
to indicate that the outbreaks of the green-bug in Oklahoma and 
Kansas are not necessarily the result of the northward migration 
of this pest from northern Texas. 
The false wireworms have become seriously abundant and 
destructive in western Kansas and Nebraska. The dry fall and 
winter in many localities prevented germination of the seed 
until this spring, and the false wireworms have consequently 
been favored by this condition. 
The corn borer that was discovered in Texas and northern 
New Mexico last summer has been determined this Fpiring as 
Diatraea lineolata Walker. The Survey carried on this spring 
indicates that in the Big Bend country of Texas the infestation 
amounts to 50 per cent of the corn. 
The seed-corn maggot again appeared on the Atlantic 
Seaboard this spring, having been reported from North Carolina 
on March 6, This pest has al30 been reported this year^in 
Alabama and Louisiana.
