Soybean gall midge (SGM), Resseliella maxima Gagné (Diptera: Cecidomyiidae), is a new pest of soybean found across multiple Midwest states: Minnesota, Nebraska, Iowa, South Dakota, and Missouri. The larvae of SGM feed on and damage soybean plant stems, causing yield reductions. Biological control of this pest seems promising as recent work discovered and identified a new parasitoid species, Synopeas maximum Awad & Talamas (Hymenoptera: Platygastridae), associated with SGM. Previous work detected S. maximum parasitism of SGM in Minnesota, but no other Midwestern states have been evaluated. Our research aims to assess SGM parasitism in multiple states using molecular tools such as qPCR. This work will form a baseline for understanding field-level parasitism rates across multiple states and therefore, the biological control potential of S. maximum on SGM in Midwestern soybean.
