As Western bean cutworm (WBC) adult trap monitoring comes to an end for the 2018 season, we would like to thank everyone for their participation including land owners and farm cooperators who allowed us to place traps in their fields. Week ending August 25, 2018 was our final week monitoring WBC adult moth catches in Ohio as very few adult moths are being reported in the bucket traps. Overall, 23 counties monitored 69 traps and resulted in a statewide average of 0.7 adult moths per trap (51 total captured). This is a decrease from an average of 1.2 moths per trap (76 total captured) the previous week.
