Abstract
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, Aphis glycines (Hemiptera: Aphididae), is the most important soybean insect pest in Iowa and is capable of reducing yield by 40%. Nymphs and adults feed on sap within the phloem and can vector several plant viruses. In Iowa, soybean aphids have been a persistent pest that can colonize fields from June through September. Their summer population dynamics are dependent on weather and other environmental conditions.
