Studies of the interactions of SCN with the soybean aphid

Investigators: Gregory L. Tylka, Matthew E. O’Neal, Felicitas Avendano
Funding: Iowa Soybean Association

The soybean aphid, Aphis glycines, was first discovered feeding on soybeans in Iowa and other Midwestern states in 2000. Since then, it has spread throughout the state and region. Currently, soybean aphids are found in every county in Iowa and the insect has become a serious yield-reducing pest of soybeans in the state.
