Alert Details

Western bean cutworm peak flight appears to be subsiding across a large portion of the corn-growing region as this insect moves through its annual generational cycle. High risks remain in a belt from Nebraska northeast into northern Iowa, southeast South Dakota, southern Minnesota, central and northern Wisconsin, northern and central lower Michigan, and also into southern Ontario, Canada. In this region, moth counts and activity are presently highest in northern Michigan southeast into southern Ontario, Canada with scattered problem areas elsewhere. Moderate risks continue from Nebraska and South Dakota northeast through Iowa, Minnesota, northern Illinois, Wisconsin, Michigan, northern Indiana, northern Ohio, northwest Pennsylvania and New York, and also into southern Ontario and southwest Quebec, Canada. The primary focus over the next few weeks will be primarily in the eastern Great Lakes region and into Canada with only isolated problems further south and west.
