Since first being detected in 2005, Western Bean Cutworm (WBC), Striacosta albicosta (Smith) (Lepidoptera: Noctuidae) has become a pest throughout most of Wisconsin. WBC was first detected in corn in southern Wisconsin and by 2006 WBC had spread into several counties in the state. Populations are most prevalent south of highway 29/Interstate 94 based on 2010 pheremone trap captures (Pestwatch, 2010). Since WBC initial collection and identification (Smith, 1887) in the late 1800s in the western United States, the pest has continued to migrate both to the north and east.
