Fall Armyworm
As more counties set up Fall armyworm (FAW) traps this week, overall averages have slightly declined from 4.2 to 3.1. Of all the reporting counties, Lucas County saw the highest number of captures with 32 moths (Figure 1). Beginning next week, trapping for Western Bean Cutworm (WBC), Corn Earworm (CEW), and European Corn Borer (ECB) will be stopped, and counties will focus on FAW.
