Resident parasitoids associated with Drosophilidae in Michigan tart cherry orchards and woodland edges

Knowledge of the distribution and abundance resident parasitoid species Drosophila flies constitutes an important base for developing implementing a biological control program suzukii (Matsumura) (Diptera: Drosophilidae), invasive pest that attacks ripening thin-skinned wild cultivated berries stone fruits. For this purpose, field survey was conducted to identify community associated with D. infested sites in tart cherry orchards woodlots west, northwest, central Michigan. Sentinel traps baited larvae pupae banana slices were deployed center orchards, adjacent isolated from any known commercial host . Traps placed beginning July end October 2021. Three are use drosophilids as hosts recovered these traps. Pachycrepoideus vindemiae (Rondani) (Hymenoptera: Pteromalidae) Leptopilina boulardi Barbotin, Carton & Keiner-Pillault Figitidae) emerged bananas. heterotoma (Thomson) collected adult sentinel trap. Among wasps, only P. successfully parasitized laboratory. This pupal abundant widely distributed both woodlots. The highest number followed by without nearby fruit having lowest detections. These findings suggest future release augmentative or classical agents could be successful post-harvest late-season populations pest.
