In Iowa, management of soybean aphids can be complicated by bean leaf beetle, Cerotoma trifurcata. A management strategy based on a June application of lambda-cyhalothrin (Warrior) can manage bean leaf beetles and may reduce the incident of bean pod mottle virus. It is possible that foliar- and seed-treatment insecticides applied to control bean leaf beetle may aid in reducing soybean aphid populations.
