Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) is a destructive crop pest native to Southeast Asia that recently invaded countries in Europe and North America, severely impacting commercial fruit production in its new host range. Here we report the results of a survey aimed at determining the presence of indigenous D. suzukii parasitoid populations carried out from May to October 2012 in two areas negatively affected by this fruit pest: Trento Province, Northern Italy, and Oregon in the Pacific Northwest of the USA. We conducted field and laboratory studies in order to determine the status of biological control agents utilizing D. suzukii as a host. Our study sites included a range of commercial soft fruits and natural non-commercial habitats. In each site, sentinel traps were baited with either D. suzukii or Drosophila melanogaster Meigen (Diptera: Drosophilidae) larvae in different food substrates. The generalist parasitoid, Pachycrepoideus vindemiae (Rondani) (Hymenoptera: Pteromalidae), was collected from both D. suzukii and D. melanogaster pupae in traps deployed in a selection of these sites. This report of P. vindemiae in 2012 represents the first identification of D. suzukii parasitoids in Europe. A successive parasitism efficacy test was set up under controlled laboratory conditions confirming the ability of P. vindemiae to attack D. suzukii pupae. In addition, an historical digression with analysis of the original documents in the Italian archives has been provided in order to unravel the correct species name. We finally discuss the possible practical implications of this finding for the biological control of D. suzukii.

- Drosophila parasitoids in northern Italy and their potential to attack the exotic pest Drosophila suzukii (2016, unknown): “…was largely used in similar studies (Novković et al. 2012; Fleury et al. 2004; Chabert et al. 2012), while blueberries were chosen both as a favorite host of D. suzukii (Kinjo et al. 2013; Mazzetto et al. 2015) and because they were already used to capture parasitoids (Rossi Stacconi et al. 2013).”
- Host stage preference, efficacy and fecundity of parasitoids attacking Drosophila suzukii in newly invaded areas (2015, unknown): “Parasitoid populations of L. heterotoma and P. vindemiae were collected from sentinel bait traps placed in close proximity to fruiting host plant species in these same regions during June–October 2011–2013, as described in Rossi Stacconi et al. (2013).”
