Corn earworm migration possibilities will be in the forecast on a nightly basis through mid-week next week as an active weather pattern is likely to be in place across a large portion of the corn-growing region. Southerly winds are likely to pump warm and humid conditions into southern and central portions of the corn-growing region, and these winds may also transport some corn earworm moths from less attractive fields in the mid-south and southern corn-growing region north over the next several days. Low risks are in place tonight mainly east of the Mississippi River as the first cold front moves east. Already by tomorrow night, however, the next weather system is likely to begin developing in the northern Plains and should spread southerly winds across the Plains into the western corn-growing region. Low risks are in place tomorrow night into Sunday morning mainly west of I-39 in Wisconsin and Illinois. Late in the weekend and early next week, Moderate risks are in the forecast across northern and eastern Iowa, Minnesota, Wisconsin, and northern Illinois especially Monday night into Tuesday with Low risks enveloping much of the remainder of the central and northern corn-growing region ahead of a stronger cold front expected to pass through mid-week. Growers with crops still at susceptible stages to damage, especially late or re-planted field corn and processing/fresh market crops should continue to actively scout and monitor traps as additional moth flights are likely in the week ahead.
