Southerly winds are expected to continue east of a cold front that will begin advancing east from the Plains through the corn-growing region over the next few days. In this southerly wind regime, isolated black cutworm moth flights are possible tonight into tomorrow as far east as Lake Michigan and eastern Illinois, and as far north as South Dakota, Minnesota, and Wisconsin. Migration risks increase tomorrow night into Saturday as the cold front moves east and the source region moves east into a more favorable region for insects across the mid-south. Moderate migration risks are predicted from Missouri and Illinois as far north as Minnesota into Wisconsin, with Low risks extending east into the Great Lakes and eastern corn-growing region. The parent low pressure system to the cold front is expected to deepen over the next few days, but eventually northwest flow behind the front will largely end any migration threat. Growers are advised that black cutworms may already be present in some areas of the corn-growing region, and regular scouting will be important this spring especially with planting underway in some areas.
