Alert Details

A predominantly northwest to southeast flow weather pattern is predicted throughout this week and potentially into at least the start of the holiday weekend. As a result, any southerly winds that could potentially cause corn earworm migrations are predicted to stay confined to the mid-south and southern states for much of this week. Therefore, no risks are in place except for a brief opportunity for a shorter distance migration from source regions in the mid-south into especially fields in the Missouri bootheel but also portions of far southwestern Illinois and western Kentucky on Wednesday night into Thursday morning. Trap counts in mid-south source regions are now beginning to show signs of increases, especially in the usual hot-spots in central Arkansas and along the Mississippi River in western Tennessee, so some moth count increases are certainly possible, at least on an isolated basis, mainly to the south of the St. Louis, Missouri area later this week.
