    Incorporating host-plant resistance into soybean aphid integrated pest management.
    (2017-09) Hanson, Anthony
    Soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), originally from Asia, is an invasive pest of soybean in North America that can damage resulting in up to 40% yield loss. Currently, foliar insecticides such as pyrethroids and organophosphates are used to control soybean aphid. Soybean resistant to soybean aphid also has been found (i.e., Rag genes), but these traits are not commonly available from seed suppliers. The following chapters focus on research identifying: soybean aphid resistant germplasm and genetic loci to increase the availability of soybean aphid resistance varieties, insecticide resistant field populations of soybean aphid, and how use of current insecticides may interact with host-plant resistance.
