Western bean cutworms have caused significant damage to some cornfields in Iowa since 2000. To assist in scouting efforts for this pest, a network of pheromone traps have been placed in areas of historical western bean cutworm activity (see map). These traps should reflect the emergence pattern within a county area. Adults (moths) are now being collected and the results can be found athttp://www.ipm.iastate.edu/westernbeancutworm. Some of the highest trap catches have been in Audubon, Crawford, and Shelby counties in west central Iowa, plus Butler County in north central Iowa. Now is the time to start scouting for western bean cutworm eggs.
