“…After about 1-2 weeks non-parasitized Drosophila individuals emerged and were removed from the emerging chambers. Parasitoids started to emerge after about 3-4 weeks and were collected and preserved in 96% ethanol at −20 • C. Morphological characters of all parasitoid specimens were inspected under the stereoscope, thereafter identified by using published taxonomic keys and related literature [45][46][47][48][49][50].…”

(1) The management of agricultural landscapes for pest suppression requires a thorough understanding of multiple determinants controlling their presence. We investigated the ecological preferences of indigenous parasitoids and their drosophilid hosts to understand the role of native parasitoids as biological control agents of the invasive frugivorous Drosophila suzukii. (2) Using data from an extensive field survey across different habitat types we analyzed the influence of abiotic and biotic factors on parasitoid and drosophilid communities at multiscale levels. (3) Eight parasitoid and 27 drosophilid species were identified. Thirty-four percent variation in drosophilid communities was explained by factors at the landscape scale, and 52% of significant variation of parasitoids by local distribution of three drosophilid species, mainly collected in woodland. Parasitoid communities were significantly influenced by microhabitat type (ground versus canopy) rather than habitat type. All parasitoids except Pachycrepoideus vindemmiae preferred the ground microhabitat. All parasitoids, with the exception of Trichopria drosophilae and Spalangia erythromera, displayed significant preferences among the drosophilid species used in the baited traps. (4) Since they can tolerate a broad range of habitat factors, altogether pupal parasitoids investigated in this study could play a role in biological control programs to suppress D. suzukii, but non-target effects have to be regarded.

“…These species are morphologically very similar to each other. However, L. heterotoma is distinguished from G. xanthopoda thanks to some morphological characteristics such as having wings covered with short hair but long at tip (Lue et al 2016).…”

The spotted wing drosophila fly, Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae), is a pest which caused serious crop losses to soft-skinned fruits such as cherries, strawberries, and grapes. In this study, population dynamics of D. suzukii and its associated parasitoids were investigated. The surveys were conducted at one location of Uşak province, Turkey, between April and December of 2017 and 2018. For this purpose, the baited traps were weekly hung on the fruit trees. Population of D. suzukii in 2017 and 2018 peaked at the end of October and in mid-November, respectively. Moreover, three parasitoid species, namely, Leptopilina heterotoma (Thomson, 1862), Ganaspis xanthopoda (Ashmead, 1896) (Hymenoptera: Figitidae), and Pachycrepoideus vindemiae (Rondani, 1875) (Hymenoptera: Pteromalidae), were identified associated with the pest. Among these, G. xanthopoda and L. heterotoma are new records for Turkey Eucoilinae fauna. P. vindemiae was the most abundant parasitoid in both years, while G. xanthopoda was detected only in 2017. This study is the first research to detect parasitoids of D. suzukii in Turkey.

“…The morphology-based research in Novković et al (2011), Buffington and Forshage (2016) and Lue et al (2016), as well as specimens in the USNM, were used to confirm the identities of the Figitidae. While this research was being conducted, it became clear that specimens of Leptopilina submitted to MLB for identification in 2016 were misidentified as Leptopilina heterotoma (Thompson).…”

We report the presence of two Asian species of larval parasitoids of spotted wing Drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), in northwestern North America. Leptopilina japonica Novkovic & Kimura and Ganaspis brasiliensis (Ihering) (Hymenoptera: Figitidae) were found foraging near and emerging from fruits infested by D. suzukii at several locations across coastal British Columbia, Canada in the summer and fall of 2019. While G. brasiliensis was found in British Columbia for the first time in 2019, re-inspection of previously collected specimens suggests that L. japonica has been present since at least 2016. Additionally, we found a species of Asobara associated with D. suzukii in British Columbia that is possibly Asobara rufescens (Förster) (known only from the Palearctic Region) based on COI DNA barcode data. These findings add to the list of cases documenting adventive establishment of candidate classical biological control agents outside of their native ranges. The findings also illustrate the need for revisiting species concepts within Asobara, as well as host and geographic distribution data due to cryptic and/or misidentified species.
