The soybean aphid, Aphis glycines Matsumura is native to Asia and was first detected in the continental U.S. in Wisconsin during 2000. By 2003, 21 U.S. states and three Canadian provinces had confirmed reports of soybean aphid. Soybean aphid was probably originally mistaken for cotton or melon aphid, Aphis gossypii Glover in the field, but soybean aphid is more likely to form high-density colonies on soybean plants. Significant yield loss can result from these aphid populations if left unchecked. Regular scouting of soybean fields and consultation with local extension specialists is necessary for proper management. Due to its recent introduction status, some biological research to improve our understanding of the insect’s life cycle and the potential for predicting pest outbreaks is still in progress. In order to assist in extension efforts and provide additional research-related information for the soybean aphid, the NPDN has partnered with the National IPM Centers, and Land Grant University specialists to incorporate the soybean aphid into the Pest Information Platform for Extension and Education, http://www.sbrusa.net/ during 2006. In addition to the soybean aphid monitoring efforts in soybean, Colorado State University led the coordination of soybean aphid monitoring for other legumes (primarily common bean, Phaseolus vulgaris) in the western U.S.
