The western bean cutworm, Striacosta albicosta (Smith) is a native North American pest of corn and dry beans. The historical geographic range of the western bean cutworm covered the western Great Plains states including Colorado, Nebraska, and Wyoming. Since 1999, the geographic range of the western bean cutworm has rapidly expanded eastward across the U.S. Corn Belt and eastern Canada, causing significant and economic damage to corn Zea mays (L.) and dry edible beans Phaseolus spp., in parts of this region. Since 2010, increasing challenges related to managing this pest in its new range prompted numerous research studies that provided new insights into the biology and management of western bean cutworm. This revision of a previous Journal of IPM profile summarizes new information regarding the ecology and biology of western bean cutworm, and discusses updated recommendations for scouting and management in corn and dry beans, with an emphasis in the expanded geographic range of the Great Lakes region.

玉米和干豆中西豆角虫（鳞翅目：夜蛾科）的生态与管理—以大湖地区为重点的修订

西部豆角虫Striacosta albicosta（Smith）是北美本地的玉米和干豆害虫。西豆角虫的历史地理范围覆盖了包括科罗拉多州，内布拉斯加州和怀俄明州在内的西部大平原州。自1999年以来，西豆角虫的地理范围已迅速向东扩展至整个美国玉米带和加拿大东部，对玉米玉米may和干食用豆菜豆造成了重大经济损失spp。，在该区域的部分地区。自2010年以来，与在新范围内管理该害虫相关的挑战日益严峻，促使众多研究为西方豆角虫的生物学和管理提供了新见解。此IPM先前期刊的修订版总结了有关西豆角虫生态和生物学的新信息，并讨论了对玉米和干豆进行球探和管理的最新建议，重点是大湖区的扩大地理范围。
