Insecticides for Control of Chinch Bugs in Wheat

Updated May 4, 2006
by Gary Hein and John Thomas

Economic Threshold:
Chinch bugs in eastern Nebraska can infest wheat in the spring and build up to levels that may be damaging to surrounding sorghum or corn in the summer when they move from ripening wheat. Thick wheat stands will be avoided by chinch bugs and likely reduce the threat of chinch bugs. Treatment for chinch bugs in wheat would seldom be warranted.
