In 2018, soybean gall midge (Resseliella maxima Gagné) was identified as a new species causing significant injury to soybean in four Midwestern states (NE, IA, SD, and MN). Since its discovery, it has been documented in 115 counties across 5 states. Little is known about its biology, ecology or management. A multi-state collaboration has been established between the entomologists in these states and several research projects are underway. This presentation will highlight some of the key observations and findings from the 2020 growing season.
