On June 1, 2005, Brian Lang, Iowa State University (ISU) Extension field specialist in crops, found soybean aphids in a soybean field near Decorah and on another field near West Union. In most cases, just one or two aphids were found on VC- and V1-stage plants, but a few small colonies of aphids were also found. In addition, Matt O'Neal, a soybean aphid researcher at ISU, found a soybean aphid nymph on a VC-stage soybean plant after looking at more than 500 plants.
