The soybean aphid is not making much of an impression in Iowa this July. Reports from across the state indicate that aphids can be found in soybeans but populations are mostly small and very scattered. Recently I had several participants at a field training school ask about the Minnesota speed sampling procedure for soybean aphids. This method was developed by Erin Hodgson, Department of Entomology, University of Minnesota. It is still being refined with additional research being collected this year.
