The Asian spotted wing drosophila, Drosophila suzukii, has recently become a serious pest of soft fruits in Europe. Classical biological control through the introduction of larval parasitoids from its native range in Asia is presently being considered. However, host specificity of potential biological control agents has to be determined to avoid releasing species that may have unintended non-target impacts. Larvae of six different European non-target fly species and the target D. suzukii were exposed either on diet or blueberries to three Asian larval parasitoids, Asobara japonica, Leptopilina japonica, and Ganaspis cf. brasiliensis, and one European species, Leptopilina heterotoma. Asobara japonica showed the lowest specificity, attacking and developing in all Drosophilidae. Leptopilina japonica successfully parasitized two non-target Drosophilidae, D. melanogaster and D. subobscura, with one singly progeny emerging from D. immigrans. Ganaspis cf. brasiliensis had the highest level of specificity but variations occurred between two geographical populations tested. A Japanese population was strictly specific to D. suzukii, whereas another population from China parasitized D. suzukii, D. melanogaster and sporadically D. subobscura. The European L. heterotoma successfully developed in D. melanogaster, D. subobscura and occasionally in D. immigrans, but nearly all eggs and larvae in D. suzukii were encapsulated. These results show that Ganaspis cf. brasiliensis is the species with the highest potential for biological control, but more studies are needed on its taxonomic status and the existence of biotypes or cryptic species varying in their specificity before field releases can be conducted in Europe.Electronic supplementary materialThe online version of this article (10.1007/s10340-018-1003-z) contains supplementary material, which is available to authorized users.

“…Current control methods, already implemented or under development include the use of fly traps, field sanitation, chemical sprays (Walsh et al, 2011) and biocontrol with parasitoid or predators, or both (Chabert et al, 2012; Cuthbertson et al, 2014; Haye et al, 2016). …”

Strawberry Accessions with Reduced Drosophila suzukii Emergence From Fruits

et al. 2016

View full text Add to dashboard Cite

Drosophila suzukii is threatening soft fruit production worldwide due to the females’ ability to pierce through the intact skin of ripe fruits and lay eggs inside. Larval consumption and the associated microbial infection cause rapid fruit degradation, thus drastic yield and economic loss. Cultivars that limit the proliferation of flies may be ideal to counter this pest; however, they have not yet been developed or identified. To search for potential breeding material, we investigated the rate of adult D. suzukii emergence from individual fruits (fly emergence) of 107 accessions of Fragaria species that had been exposed to egg-laying D. suzukii females. We found significant variation in fly emergence across strawberries, which correlated with accession and fruit diameter, and to a lesser extent with the strawberry species background. We identified accessions with significantly reduced fly emergence, not explained by their fruit diameter. These accessions constitute valuable breeding material for strawberry cultivars that limit D. suzukii spread.

“…Drosophila suzukii can attack and develop in a very large range of wild and cultivated fruits as well as in fruits of ornamental plants Lee et al, 2015). In addition to its broad host range, D. suzukii probably owes its invasive success to the lack of effective natural enemies and competitors in the invaded area (Haye et al, 2016), a high fecundity and a short development time (14 days at 22°C), enabling it to develop up to 13 generations per year (Asplen et al, 2015;Tochen et al, 2014Tochen et al, , 2016.…”

“…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.…”

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 ...
