Brief Project Summary:

Research on soybean aphids is a relatively new effort in South Dakota. This project supports the SDSU program to study the management and ecology of soybean insects. The long-term scientific goal of the research effort is to develop an IPM system for soybean insect pests that minimize insecticide use and costs, while maximizing the role of natural enemies and resistant soybean varieties.

Information And Results
Project Deliverables

Aphids will be monitored weekly and the plots will be treated with insecticide based on scouting data, and yields will be compared at the end of the season for the four scouting practices;
1. Initiate field screening for aphid resistance in soybean germplasm breeding lines. This effort involves field studies where several soybean lines are compared to susceptible soybean cultivars;
2. Expand the release and monitoring program for the soybean aphid parasitoid, Binodxys communis. Working with other entomologist in the North Central Region, Dr. Tilmon will participate in the parasitoid release program.
3. Conduct a field study to determine the interaction between natural enemies and resistant soybean varieties for soybean aphid suppression. The effort involves developing information on whether the actions of natural enemies and resistant varieties are additive, or whether plant resistance impacts the biological controls.

Final Project Results

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
