Abstract

Black cutworms are an occasional pest of seedling corn that can cause significant damage. A pheromone trap was placed at the research farm in 2008. The peak flight of seven moths occurred on May 8. The moth flights are used to anticipate when cutting from black cutworms would begin and therefore predict when scouting should begin. Based on this monitoring data and data from other locations in west-central Iowa, the scouting date was May 20. This scouting date was 2 days later than 2007.
