Trap captures of western bean cutworms exploded at the end of the second week in July. Moth catches in a blacklight trap north of Correctionville were 1,130 (July 12), 2,244 (July 13), and 1,018 (July 14). Todd Vagts, Iowa State University Extension field specialist-crops, has developed a Web site showing western bean cutworm trap captures in several western Iowa locations.
