Abstract
The confirmation of soybean aphid, Aphis glycines (Hemiptera: Aphididae), in 2000 has drastically changed soybean pest management in the United States. Outbreak populations (i.e., 1,000’s per plant) can significantly reduce yield by 40 percent, and reduce seed size, seed coat quality, pod number and plant height (Ragsdale et al. 2007). As a result of the yield loss potential, soybean aphid quickly became the primary soybean pest in Iowa and the north central region. A soybean efficacy evaluation was started at ISU in 2005 and continues to grow with the availability of new products and management tools.
