Soybean Aphid: A New Pest for North America - Higgins, Randy (My University, 2017)
The soybean aphid (Aphis glycines), originally a native of China and Japan, was first identified in the United States during the summer and fall of 2000. Infestations were confirmed in several Midwestern states from Ohio to West Virginia and Kentucky, west into Missouri and Iowa. Late last summer, the heaviest infestations were located in Michigan, Wisconsin, Minnesota, and Illinois. At the moment, we do not know of confirmed infestations within the state of Kansas, with the nearest verified sightings occurring about midway through Iowa and Missouri.
