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.
