Corn Earworm
A fairly active weather pattern is expected in the next week with a potential heat dome building into the corn-growing region by late week and next weekend on increasing southerly winds. These southerly winds may also bring some isolated corn earworm moth flights, although host plants are at a more attractive stage of growth right now so flights are still expected to be small further north. This should change, however, over the next few weeks. Low risks are predicted ahead of a cold front tonight into tomorrow mainly from Kansas and Missouri northeast as far as Minnesota and Wisconsin. The Low risks shifts east a little bit tomorrow night into Wednesday and focuses mainly east of I-35 but west of I-75, or from eastern Kansas and Missouri into eastern Iowa, far southeast Minnesota, Wisconsin, and east into lower Michigan, Indiana, and far western Ohio. As a potential heat dome builds late week into next weekend, Low risks focus during the night west of the Mississippi River Thursday night into Friday and then as far east as southwest lower Michigan and Indiana by Friday night into Saturday.
