Alert Details

Peak flight of western bean cutworm is ongoing especially across portions of the Great Lakes region and into Canada. High flight risks are in place from northeast Iowa and southeast Minnesota eastward through Wisconsin, lower Michigan, northern Ohio, northwest Pennsylvania/New York, and also into Ontario, Canada. Moderate risks extend from western Iowa and southern Minnesota east through the Great Lakes and also into southwest Quebec, Canada where trap counts continue to increase. Growers located in the eastern Great Lakes region should be especially vigilant for new moth activity where peak flight is likely occurring at the greatest rate. Any growers in the Moderate/High risk areas, however, should monitor their fields for moth activity, egg laying, and potentially new larvae appearing in their fields.
