CEEEAL AND FORAGE-CROP INSECTS 
WHEAT 
HESSIAN FLY ( Phytophaga destructor Say) 
Indiana. W. B. Noble (January 20): Apparently most of the late fall "brood 
succeeded in completing their growth and forming puparia. Volunteer 
wheat taken from the field today showed only about 10 percent still in 
the larval stage. These larvae were from half grown to mature and were 
apparently still alive. (February 17): Dissection of puparia taken from 
volunteer wheat in a field near La Fayette on February S showed practic- 
ally no mortality, no Withstanding severe weather. Many of the larvae 
they contain are now pupating in the greenhouse. 
Missouri and Kansas. E. T. Jones (January): A survey early last November 
indicated that a moderate though potentially important infestation in 
southeastern Kansas and southwestern Missouri had developed from second- 
brood hessian flies over an area where infestation by the first brood 
was comparatively light. The larvae were from half grown to full grown 
and later developed into second-generation puparia. 
Arkansas. Dwight Isely (February 29): For many years hessian fly was not 
considered a problem in Arkansas because so little wheat was grown. 
During the past few years, however, the wheat acreage has increased 
considerably, owing to removal of other crops from the land. Much of 
this wheat has been sown early for pasture. Practically all of the 
early sown wheat in Washington County (in northwestern Arkansas) is 
infested. In some fields 50 percent of the plants are dead and the 
others are infested, 
Oklahoma. F. A. Fenton (February 29): A few observations made last fall in- 
dicated a heavier infestation than for many years. The infestations are 
apparently scattered, but occur in Garfield County in the heart of the 
wheat belt of the State; however, we do not anticipate serious damage 
in the State this year. 
CHI ITCH BUG (Blissus leuco-oterus Say) 
Indiana. C. Benton (February 18): A mortality of H9 percent, evidently 
due to the severe winter, was observed in a total of l,UUg chinch bugs 
present in 25 samples of bunch grasses taken in Tippecanoe County on 
February 10 and lH. In two samples from exposed situations the mortality 
was 9S percent. 
Oklahoma. F. A. Fenton (February 29): The past winter has been marked by 
longer periods of cold weather than any winter for some years. General 
observations indicate that it lias had no serious effect on the chinch 
bug. Records taken by students show an average of lUU chinch bugs per 
square foot on the college farm at Stillwater, the range being from 20 
to 267* Thesa records were taken in the most favorable type of hiber- 
nating quarters that we could find, i. e. , in a good bunch-grass vicinity
