Soybean, Glycine max (L.), grown in Iowa and most of the north central region of the United States has not required regular insecticide usage. Soybean aphid glycines (Hemiptera: Aphididae), is the most important soybean insect pest in Iowa and is capable of reducing yield by 40 percent if left untreated. Some populations of soybean aphid have become resistant to pyrethroid insecticides. This creates a need to evaluate new insecticidal modes of action for crop protection.
