Black Cutworm
Low black cutworm migration risks will continue for the next couple nights to the east of a slowly-moving cold front. South to southwest winds will continue east of this front, and will also be originating in a favorable black cutworm moth source region so isolated flights will continue to be a possibility until this front moves east. Low risks tonight focus mainly along and southeast of a line from near Springfield, Missouri to Chicago, Illinois, with the risk tomorrow night focusing mainly to the east of I-57 in eastern Illinois across the southern Great Lakes and eastern corn-growing region. Little to no risk is predicted into early next week, but growers should continue to monitor traps and more importantly monitor calculated degree days from documented flights in April and early May as some new larvae may now be appearing in newly-emerged corn fields.
