Notes and new records for parasitoids of exotic drosophilids in Indiana, USA (Hymenoptera: Figitidae and Braconidae)

We report the first detection of two parasitoids of the invasive spotted-wing drosophila, Drosophila suzukii (Matsumura), in Indiana, USA: Leptopilina japonica Novković & Kimura (Hymenoptera: Figitidae) and Asobara c.f. rufescens (Hymenoptera: Braconidae). These wasps, newly reported here from Indiana, were detected in the drowning solution of Scentry spotted-wing drosophila monitoring traps located in a blueberry orchard in northern Indiana. These parasitoids were detected in monitoring traps from 10-June-2024 until 19-Aug-2024, with more detections of L. japonica than A. c.f. rufescens. We also report detection of the African fig fly, Zaprionus indianus Gupta (Diptera: Drosophilidae), in the drowning solution of traps on two dates at the end of the monitoring period in August. Our observations extend the known range of these D. suzukii parasitoids and suggest that parasitoids and their Drosophila hosts may be surveyed simultaneously in the same traps and bycatch of ongoing fly surveys could be leveraged for parasitoid monitoring.
