Alert Details

For most of the corn-growing region, the annual western bean cutworm moth flight is winding down and with most crops now advancing into less favorable egg-laying and feeding stages, overall risks are being reduced. Nonetheless, some areas are still in Moderate risks where crop stages are still vulnerable and where moths are also present, including some fields in central/northern Nebraska and also in the Central Sands and adjacent areas of Wisconsin. The primary focus now is in the eastern Great Lakes from central lower Michigan east into Ontario and Quebec, Canada, but even in these areas the annual flight is beginning to show signs of winding down. Nonetheless, Moderate risks continue in these areas given a larger variety of host plants/crops that may see damage. Lower risks are found as far south/west as northern Kansas and northeast Colorado, north as far as South Dakota and Minnesota and east into western Iowa and far northwest Missouri for the western risk area, and then a few much more isolated issues may still be seen in northern Indiana and Ohio, as well, but the primary focus region now is the eastern Great Lakes and into southeastern Canada.
