Alert Details

Low corn earworm migration risks will remain in the forecast on a nightly basis across the heart of the corn-growing region through the weekend and into very early next week. South to southwest winds and an increasingly warm to hot and humid weather pattern may lead to a few corn earworm moths flying north from source regions in Texas and also further north into the mid-south. Host plants in the source region, however, are still at an attractive growth stage to corn earworms so any flights into the corn-growing region should be isolated and generally minor in quantity. Low risks extend from Kansas and Nebraska east into Illinois and as far north as extreme southern Minnesota and Wisconsin the next couple nights, with the risk area extending further east into Indiana and far southwest lower Michigan by Sunday night and Monday morning. A cold front and likely weather pattern change back to northwest flow will virtually eliminate any migration risk by early next week.
