Western Bean Cutworm Monitoring: Week 2 Update

Western bean cutworm moth

The second week of Western bean cutworm (WBC) monitoring resulted in low moth counts for all participating counties. Traps monitored from June 28 – July 4 had a total of 55 adult moths (0.6 statewide average moths per trap; Figure 1). This is an overall increase from monitoring last week ( At this time, the majority of counties have low WBC averages, indicating scouting for egg masses is not necessary. Typically, WBC numbers peak in July, so we anticipate trap counts to continue to increase over the next couple of weeks.
