Insecticide Resistance Management For Aphis glycines (Hemiptera: Aphididae): Understanding The Biological Mechanisms And Farmer Practices

Abstract

Soybean aphid (Aphis glycines Matsumura) (Hemiptera: Aphididae) is a pest that can severely impact soybean crops in the United States. Over the years, the repeated and widespread use of pyrethroid insecticides has led to the selection of resistant individuals within soybean aphid populations. The two insecticide resistance mechanisms documented in soybean aphids are metabolic detoxification and target site alteration. Farmers are key in implementing integrated pest management (IPM) and insecticide resistance management (IRM) strategies to manage soybean aphids. Resistance mechanisms are constantly evolving, insecticide resistance is becoming a barrier to soybean aphid control, and current farmer management approaches are unknown. My dissertation is focused on understanding the variability of resistance mechanisms and farmers practices to help inform IPM and IRM.
