Very few Western bean cutworm (WBC) numbers were reported in traps for the week of August 17 – 23. Overall, a total of 26 counties monitored 84 traps, resulting in 30 WBC adults (a statewide average of 0.37 moths per trap) (Figure 1). The low numbers we are observing are expected this time of the year as peak adult flight is now behind us. We would like to thank all the participating Extension Educators that monitored WBC flight this year.
