    Soybean Aphid Efficacy Evaluation in Northeast Iowa

    Authors: , ,

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 pest in Iowa and is capable of reducing yield by 40 percent. 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.
