Abstract
Soybean aphid (Aphis glycines Hemiptera: Aphididae) is the most economically important insect pest of soybean in the North Central United States. An unmanaged aphid outbreak can reduce yield by 40 percent. Foliar insecticides are the most widely used management strategy to protect against yield loss from soybean aphids, but recent resistance to insecticides has been reported. Using varieties with aphid resistance genes (Rag) also is an effective strategy to suppress aphids and can replace insecticides. Additionally, a pyramid of two Rag genes offers more protection against aphids than a single Rag gene. This project partnered with CortevaTM Agriscience to evaluate elite soybeans with and without aphid resistance as a means to combat soybean aphid outbreaks.
