Western Bean Cutworm trapping in the Panhandle and Southwestern Nebraska

Western Bean Cutworm trapping in the Panhandle and Southwestern Nebraska

By the end of the week on August 28, trap data is beginning to indicate the end of moth flights. Overall, the populations in 2026 have been high. In dry beans, scout now across Western Nebraska and consider treatment if pod feeding exceeds 0.5-1%; the ideal treatment window is 10-21 days after flight peak. In corn, if the larvae have moved down the silk in ears, contact insecticides will not be effective.
