Western Bean Cutworm
High western bean cutworm risks are predicted mainly across portions of Nebraska, far northwest Missouri, and into Iowa where peak flight is either ongoing or is expected to increase to near peak flight levels in the next five days. Additionally, fields from central into southeast Michigan and southern Ontario, Canada have a High risk in the next five days. Trap counts or field reports in these areas indicate the presence of rather high trap counts in many areas and egg laying is either likely or has been reported. Moderate risks extend from Nebraska and northern Kansas into southeast South Dakota, southern Minnesota, Iowa, northern Missouri, northwest Illinois, Wisconsin, lower Michigan, northern Indiana, northern Ohio, northwest Pennsylvania, western New York, and Ontario, Canada. Growers all across the corn-growing region, but especially in the Moderate and High risk areas, should monitor their fields for signs of western bean cutworm and take appropriate action if needed.
