“…drosophilae was found occurring, with up to 10.7 % SWD parasitism, in two heavily infested commercial strawberry fields of Northeastern Spain, and its basic biology was preliminarily described in the laboratory (Gabarra et al 2015). As with P. vindemmiae, Rossi Stacconi et al (2015) confirmed the ability of this species to develop in SWD under laboratory conditions. A greater understanding of the host-parasitoid interactions between these two generalist parasitoids and SWD is now both warranted and needed.…”

“…A similar result has been found for two other species of this genus, L. victoriae and L. clavipes . A new report (Rossi Stacconi et al 2015) demonstrates geographic variation in the ability of L. heterotoma to develop within SWD between Italian (capable of development) and North American (Oregon; incapable of development) strains; however, this result was found using laboratory assays that may not accurately reflect field conditions. Furthermore, contrary to the fact that A. tabida emergence has been reported from field sampled Japanese SWD populations (Mitsui et al 2007), laboratory studies using European populations failed to observe successful parasitism of SWD by this species (Chabert et al 2012;Kacsoh and Schlenke 2012).…”

The Asian vinegar fly Drosophila suzukii (spotted wing Drosophila [SWD]) has emerged as a major invasive insect pest of small and stone fruits in both the Americas and Europe since the late 2000s. While research efforts have rapidly progressed in Asia, North America, and Europe over the past 5 years, important new insights may be gained in comparing and contrasting findings across the regions affected by SWD. In this review, we explore common themes in the invasion biology of SWD by examining (1) its biology and current pest status in endemic and recently invaded regions; (2) current efforts and future research needs for the development of predictive models for its geographic expansion; and (3) prospects for both natural and classical (=importation) biological control of SWD in invaded habitats, with emphasis on the role of hymenopteran parasitoids. We conclude that particularly fruitful areas of research should include fundamental studies of its overwintering, host-use, and dispersal capabilities; as well as applied studies of alternative, cost-effective management techniques to complement insecticide use within the integrated pest management framework. Finally, we emphasize that outreach efforts are critical to effective SWD management by highlighting successful Communicated by M. Traugott.

In just a few years, the Asian fly Drosophila suzukii has invaded several continents and has become a very serious pest of many fruit crops worldwide. Current control methods rely on chemical insecticides or expensive and labour-intensive cultural practices. Classical biological control through the introduction of Asian parasitoids that have co-evolved with the pest may provide a sustainable solution on condition that they are sufficiently specific to avoid non-target effects on local biodiversity. Here, we present the first study on the development of three larval parasitoids from China and Japan, the Braconidae Asobara japonica and the Figitidae Leptopilina japonica and Ganaspis sp., on D. suzukii. The Asian parasitoids were compared with Leptopilina heterotoma, a common parasitoid of several Drosophilidae worldwide. The three Asian species were successfully reared on D. suzukii larvae in both, blueberry and artificial diet, in contrast to L. heterotoma whose eggs and larvae were encapsulated by the host larvae. All parasitoids were able to oviposit one day after emergence.Asobara japonica laid as many eggs in larvae feeding in blueberry as in artificial diet, whereas L. heterotoma oviposited more in larvae on the artificial diet and the Asian Figitidae oviposited more in larvae feeding on blueberry. Ganaspis sp. laid very few eggs in larvae in the artificial diet, suggesting that it may be specialized in Drosophila species living in fresh fruits. These data will be used for the development of a host range testing to assess the suitability of Asian parasitoids as biological control agents in invaded regions. K E Y W O R D SAsobara, Ganaspis, invasive species, Leptopilina, pre-oviposition period, spotted wing drosophila short development time of the fly, they have to be applied regularly and can cause severe environmental and health concerns (Bruck et al., 2011;Cuthbertson, Collins, Blackburn, Audsley, & Bell, 2014;Sampson, Werle, Stringer, & Adamczyk, 2017;Smirle, Zurowski, Ayyanath, Scott, & MacKenzie, 2017;Van Timmeren & Isaacs, 2013).Cultural management such as the use of insect-proof nets, mass trapping and removal or solarization of infested fruits are also used, but these strategies are expensive and labour-intensive and have to be adjusted to each type of fruit crop or cultivation system (Haye et al., 2016). New control techniques focusing on long-term management are therefore urgently needed. As wild host plants constitute a large reservoir of individuals that can potentially reinvade field crops, controlling the pest at a landscape level is essential.A number of natural enemies are known to have an impact on the dynamics and regulation of Drosophila spp. and may provide an area-wide control of fly populations (Carton, Bouletreau, Lenteren, & Alphen, 1986;Fleury, Gibert, Ris, & Allemand, 2009).Two generalist pupal parasitoids, Trichopria drosophilae Perkins (Hymenoptera, Diapriidae) and Pachycrepoideus vindemmiae (Rondani) (Hymenoptera, Pteromalidae), are found attacking D. suzukii worldwide ...

Parasitic wasps inject various virulence factors into the host insects while laying eggs, among which the venom proteins, one of the key players in host insect/parasitoid relationships, act in host cellular and humoral immune regulation to ensure successful development of wasp progeny. Although the investigations into actions of venom proteins are relatively ample in larval parasitoids, their regulatory mechanisms have not been thoroughly understood in pupal parasitoids. Here, we identified a venom protein, Kazal-type serine protease inhibitor, in the pupal ectoparasitoid Pachycrepoideus vindemiae (PvKazal). Sequence analysis revealed that PvKazal is packed by a signal peptide and a highly conserved "Kazal" domain. Quantitative polymerase chain reaction analysis recorded a higher transcript level of PvKazal in the venom apparatus relative to that in the carcass, and the PvKazal messenger RNA level appeared to reach a peak on day 5 posteclosion. Recombinant PvKazal strongly inhibited the hemolymph melanization of host Drosophila melanogaster. Additionally, the heterologous expression of PvKazal in transgenic Drosophila reduced the crystal cell numbers and blocked the melanization of host pupal hemolymph. Our present work underlying the roles of PvKazal undoubtedly increases the understanding of venom-mediated hostparasitoid crosstalk.
