“…Previous work reported Synopeas maximum as a putative parasitoid of (i.e., associated with) R. maxima 10 . Synopeas are known to attack only cecidomyiids 34 and stem associated cecidomyiids, other than R. maxima , were rare in our samples. From the rearing buckets, detection of non‐target cecidomyiids was infrequent and comprised only Lestodiplosis spp.…”

BACKGROUNDSoybean gall midge, Resseliella maxima Gagné (Diptera: Cecidomyiidae), is a pest that impacts soybean yield in the Midwest US. While biological control using parasitoids may be a promising approach for managing this pest, it is crucial to have a deep understanding of parasitism dynamics to ensure effective implementation. We investigated R. maxima parasitism using a combination of three methods: rearing of field‐collected hosts, dissection, and molecular assays.RESULTSWe confirmed parasitism of R. maxima by the recently described wasp Synopeas maximum Awad & Talamas (Hymenoptera: Platygastridae) and used our combinatorial approach to observe the spatial and temporal relationships between R. maxima and its parasitoid in the field. The number of R. maxima adults was greater in symptomatic plants on field edges than the field interior, but such a pattern was inconsistent for parasitism rates. Parasitism rates were generally highest early and late in the season, and lower in the middle of the season when the number of R. maxima was highest.CONCLUSIONIn Minnesota, overall season‐long parasitism rates of R. maxima were low (<2%). To facilitate a wider investigation of the biological control of R. maxima, we designed a protocol for high throughput DNA extraction and real‐time PCR that can be used across a broader geography. Further research should evaluate how parasitism rates by S. maximum could be promoted in production fields.This article is protected by copyright. All rights reserved.
