Funding from the North Central Soybean Research Program and the North Central Integrated Pest Management (IPM) Center allowed the soybean entomology lab at Iowa State to establish four soybean aphid suction traps during the 2005 growing season. The traps are designed to capture soybean aphids as they migrate to new soybean fields or back to buckthorn, their overwintering host. The traps are composed of a 20-foot vertical tube with an electric fan at the base. The fan pulls air through the tube and deposits aphids into an alcohol-filled jar. The jar is replaced every week and the contents are sent to David Voegtlin at the Illinois Natural History Survey.
