Swenk, M. H. & Tate, H. D. (1941). Control of the chinch bug in Nebraska (University of Nebraska Experiment Station Circular No. 61)
The chinch bug, Blissus leucopterus (Say), is one of the most injurious insect pests of cereal crops in the United States. Although some damage by it has occurred over a wide area in the United States, the greatest injury has been in the Corn Belt. The years in which the chinch bug appears in destructive abundance come irregularly in cycles of varying duration, and the length of these cycles is largely controlled by the direct or indirect effects of weather upon the bugs. Continued dry weather favors them, while very wet weather brings about their destruction. During the last seven decades there have been seven separated and well-marked chinch bug outbreaks or periods of serious damage in Nebraska, and an eighth one which began in 1938 is in progress at the present time.
