Western bean cutworm (WBC) trap counts for the week of August 10 – 16 decreased over the past week putting all monitoring counties below scouting threshold. The low numbers indicate we are officially past peak flight. Overall, a total of 27 counties monitored 90 traps, resulting in 38 WBC adults (a statewide average of 0.4 moths per trap) (Figure 1).
