Abstract

Western bean cutworms continue to be a concern, especially in western Iowa. Joel DeJong, Iowa State University Extension field specialist-crops, reports fields above the economic threshold of eight egg masses per 100 plants in Cherokee, O'Brien, and Woodbury counties. The highest egg count was 20 egg masses per 100 plants. Nightly catches in a blacklight trap north of Correctionville have dropped from the peak on July 13 but still remained high (more than 500 per night) through July 21.
