Alert Details

Low corn earworm migration risks are in the forecast for the next five days especially across the central and eastern Corn Belt where persistent south to southwest winds are predicted. Low pressure is expected to move from the Plains into the Northern Plains and upper Midwest by tomorrow and eventually into the Great Lakes region by early next week. A cold front will slowly sag to the southeast while high pressure remains in the southeast United States. Increasingly southwesterly winds blowing northeast from source regions in the mid-south may allow some isolated corn earworm flights especially from Iowa and Missouri east into Ohio and potentially as far north as Michigan and southwest Ontario, Canada through the next five days. Latest trap counts from the mid-south, however, continue to show few, if any, corn earworm moths present. Additionally, with crops so far behind schedule in the eastern Midwest, only Low migration risks are predicted at this time despite a rather favorable weather pattern.
