ABSTRACT
Conditions in the United States are most favorable for insects, because the continuous growing of the same grain crops over wide areas, and long, hot summers are very propitious for the multiplication of most species. Since a season favorable to one insect may be unfavorable to another, there is also a more or less marked rotation of different species. The Hessian fly is the worst insect enemy of growing wheat. In case of mild infection, the prompt use of fertilizer may increase the tillering of the wheat so as to produce a partial crop. Hibernating in grass stools, straw, rubbish or other shelters, the chinch bug begins its life cycle by a spring flight to the wheat fields. Other Insect Enemies of stored wheat and its products are the Indian-meal moth, the meal snout-moth, the flour beetles, the meal worms and the grain beetles, which all occasion more or less damage.
