Insect pests in soybean continue to pose challenges.  After a couple relatively “quiet” years for soybean aphid, a widespread aphid outbreak occurred in 2024. This presentation will review soybean aphid management, include research results on the efficacy (or lack thereof) for various insecticides. The soybean gall midge is a newer pest in Minnesota soybean. The biology and management of this pest will be reviewed, including exciting updates related to biological control of this pest.
