The soybean aphid, Aphis glycines, is a new invasive species in North America, and a potentially serious pest of soybeans, both due to its capacity for direct damage, and its ability to vector plant viruses. We monitored aphid populations across the state of Indiana throughout the summer with the aid of county extension educators. We also conducted intensive studies on the population dynamics of the aphid in relationship to the age of their soybean hosts. Finally we examined the impact of Orius insidiosus on aphid populations, both in open field, and inclusion cage studies.
Species 1: Homoptera Aphididae Aphis glycines (soybean aphid)
