Western bean cutworm (WBC) numbers continue to decrease over the past week, with a total average of 0.86 moths across the state. This decline suggests we are past peak WBC season as no counties reported being above threshold (an average of 7 or more moths for the week) recommended for scouting (Figure 1). With this decrease, many counties will be replacing WBC monitoring with FAW as more counties set up FAW traps this week.
Fall Armyworm
Fall armyworm (FAW) (Figure 2) numbers increased slightly over the past week with, three counties reporting moth captures. These counties include Madison, Van Wert, and Wayne. Clark county was also monitoring for FAW but reported finding 0 moths (Figure 3). This increases the statewide average from 1.8 to 2.3. As WBC numbers continue to drop, additional counties will begin monitoring for FAW over the next couple of weeks.
Corn Earworm
The number of Corn Earworm (CEW) has slightly increased over the past week going from a statewide average of 1.4 to 2.8. While moths continue to be reported in five of the monitoring counties, the numbers remain low across the state (Figure 4). Muskingum Co. reported the highest moth count with an average of 18 moths over the past week.
European Corn Borer
This week's numbers for European Corn Borer (ECB) have decreased from last week but two reporting counties continue to report moths (Figure 5). The two counties that found ECB over the last week were Fulton and Muskingum counties. Overall, the average is very low statewide with 0.2 ECB-IA and 0 EBC-NY.
