The goal of this project is to develop a better understanding of where the soybean aphid overwinters, and when and how it colonizes in Wisconsin, soybean fields in the spring. We know that soybean aphids migrate from soybeans to buckhorn in the late summer and early fall, where it undergoes a sexual generation and produces the overwintering egg stage. The eggs hatch in the spring and after several generations developing on buckhorn; they develop winged aphids and migrate to soybean fields.
