After a few nights of no corn earworm migration risks, Low risks return to the forecast on Thursday night into Friday as a new low pressure system and attendant cold front develop in the Plains states and moves east through the corn-growing region. Southerly winds will increase ahead of this feature, and may pose an isolated migration risk at that time mainly across eastern Kansas, Missouri, Iowa, far eastern Nebraska, southern Minnesota, and into portions of western Illinois. Low risks continue mainly between I-35 and I-75 on Friday night into Saturday morning from western Missouri and central Iowa east into western Ohio and southern lower Michigan. As the front continues east Saturday into Sunday, Low risks continue mainly to the east of I-57, or eastern Illinois and points east, at that time. Growers should continue to monitor traps and scout fields, especially if crops are at a susceptible stage to damage, as some moth flights may have occurred in the last week or so.
