1. Evaluate soybean yield loss at different aphid densities in a field cage experiment and in field surveys in order to define an economic injury level (EIL) for New York. 2. Conduct a survey of soybean variety trials to determine relative abundance and yield impacts of soybean aphid, Aphis glycines Matsumura on commonly grown soybean varieties in New York. 3. Conduct a survey to determine the identity of natural enemies (predators, parasitoids and fungal pathogens) affecting soybean aphid in New York State. Evaluate the importance of these natural enemies for controlling soybean aphids while soybean plants grow and soybeans develop. 4. Enhance cooperative extension outreach efforts, communication, networking, regarding soybean aphid, optimize rapid and early detection of this exotic pest: Continue to increase awareness of soybean aphid and its importance NY field personnel (producers, crop consultants, agricultural industry, field crop extension educators). Utilize electronic technology and traditional approaches to strengthen timely communication and convey survey activities and findings to Northeast region clientele, and other appropriate stakeholders. 5. Share survey findings with appropriate soybean IPM workers in the Northeast and north central US (Northeast IPM and NC 502), state and federal agencies (USDA National Agricultural Pest Information System (NAPIS), USDA Cooperative Agricultural Pest Survey (CAPS), and USDA Animal Plant Health Inspection Service (APHIS)).
