Abstract

The list of caterpillars defoliating soybean in Iowa continues to lengthen. Both black cutworms and variegated cutworms have cut soybean fields throughout the state. Black cutworms in soybean have become more common in the past 3 years, but variegated cutworms in soybean were totally unexpected. Variegated cutworms may have one or two more generations this year but soybean should grow out of the stage in which plants are susceptible to cutting. Defoliating caterpillars should be the primary concern for the remainder of the growing season.
