Figures 3 and 4 show the total number of true armyworm and black cutworm moths reported, respectively, in each county from April 1 to June 1. Data is current as of June 5, 2023.Īlthough more total moths in an area does not necessarily mean you can expect more damage to occur, knowing where moths were captured can give an idea of where to expect activity. The bold number indicates the total moth count for the week (for counties with multiple sites, only the site with the highest total moth count is reported), while the smaller number in parentheses is a running total of the moth count for that trap location. Black cutworm moth captures from May 21 to May 30. Data is current as of June 5, 2023.įigure 2. True armyworm moth captures from May 21 to May 30. No additional significant flights of black cutworm occurred during Week 8.įigure 1. Most of these reports occurred between May 21 and May 23. Week 8 report:ĭuring the final days of the trapping network (May 21 to May 30), our cooperators reported 7 TAW (Figure 1) and 32 BCW (Figure 2) moths statewide. Because of these efforts, we were able to provide weekly updates of moth activity and predict cutting dates for BCW in Iowa.

A total of 34 BCW and 34 TAW traps were placed and monitored during April and May. To recap, we had 31 volunteers participate from 26 counties in Iowa. We appreciate our cooperators for tirelessly checking traps the last two months and reporting their captures so we can provide the most accurate scouting information for these pests. The trapping season for true armyworm (TAW) and black cutworm (BCW) has come to an end.
