Alert Details

Western bean cutworms will continue to show an increasing presence across a good portion of the corn-growing region in the next week. Peak flight continues especially across portions of far northern Kansas and Nebraska, but there are signs that the primary focus is in sections of Nebraska as counts are beginning to decrease in some spots near the Kansas and Nebraska border. High risks remain across this area with additional sections of western Iowa and northwest Missouri also included. Moderate risks for increasing moth counts and also potential egg laying are in place from Kansas and Nebraska northeast into far southeast South Dakota, northern Missouri, Iowa, southern Minnesota, Wisconsin, far northern Illinois, southern Michigan, northern Indiana, northern Ohio, northwest Pennsylvania, and also southwest Ontario, Canada and far southwestern New York. Growers across the corn-growing region should monitor their fields closely for signs of western bean cutworms and also potential egg-laying, and take appropriate action if it is needed!
