“…Even stronger than D. melanogaster , D. suzukii defends itself against larval parasitoids by encapsulating and subsequent melanising the parasitoid eggs within the larval tissue4748. However, the immune response of the flies seems to be costly, as it is associated with a reduced feeding rate49 and a reduced fecundity of the surviving adults505152. Furthermore there appear to be indirect fitness costs as P. vindemmiae has been found to preferentially parasitize pupae of hosts that had been attacked as larvae by A. tabida 53.…”

Since its introduction into Europe the invasive Drosophila suzukii has established and spread widely, thereby entering habitats populated by native Drosophila species and their natural enemies. The highly prolific D. suzukii will likely interact with these species as a competitor, host or prey. To investigate potential interactions of D. suzukii with parasitoids, a field survey was conducted across several fruit-growing regions in Switzerland in two consecutive years. Eight species of hymenopteran parasitoids were collected using D. melanogaster as sentinel hosts in field-traps. Parasitoid capture was much higher in 2015 than in 2014 and varied among regions, time of the growing season, and habitat type. Laboratory no-choice assays with the field-collected species demonstrated that the larval parasitoids Asobara tabida, Leptopilina boulardi, and L. heterotoma could not use D. suzukii for reproduction, although the latter two reduced the number of emerging D. suzukii. In contrast, the pupal parasitoids Pachycrepoideus vindemmiae, Trichopria drosophilae, Vrestovia fidenas and Spalangia erythromera all developed with D. suzukii as hosts. Regional differences between strains were generally not evident, with the exception of two T. drosophilae strains that differed in parasitization rate. Thus, native parasitoids may interact with D. suzukii and should be regarded when implementing pest control measures.

“…The immune response may also differ depending on the species of Drosophila even with the same cells involved. Indeed, the D. suzukii encapsulation response to Leptopilina wasp eggs shows a timing very far from that known in D. melanogaster (Iacovone et al., 2018). The immune response was not noticeable on L. heterotoma parasitoid eggs during the first 48 h (Figure 2) and only a thin coat of lightly colored cells wrapped the hatched larvae 72 h post-oviposition.…”

Host-parasitoid interactions are among the most studied interactions between invertebrates because of their fundamental interest – the evolution of original traits in parasitoids – and applied, parasitoids being widely used in biological control. Immunity, and in particular cellular immunity, is central in these interactions, the host encapsulation response being specific for large foreign bodies such as parasitoid eggs. Although already well studied in this species, recent data on Drosophila melanogaster have unquestionably improved knowledge of invertebrate cellular immunity. At the same time, the venomics of parasitoids has expanded, notably those of Drosophila . Here, we summarize and discuss these advances, with a focus on an emerging “time-dependent” view of interactions outcome at the intra- and interspecific level. We also present issues still in debate and prospects for study. Data on the Drosophila -parasitoid model paves the way to new concepts in insect immunity as well as parasitoid wasp strategies to overcome it.

“…When D. suzukii became established in Europe and North America, several studies characterized indigenous parasitoids that could potentially include D. suzukii in their host spectrum [ 27 , 28 , 29 , 30 , 31 ]. In Europe, hymenopteran larval parasitoids, Asobara tabida (Nees, 1834) (Braconidae), Leptopilina boulardi (Barbotin, Carton and Kelner-Pillault, 1979) and L. heterotoma (Thomson, 1862) (Figitidae), did either not parasitize D. suzukii or their eggs were encapsulated by the host [ 32 ]; however, egg laying by the latter two still reduced the fitness of D. suzukii [ 30 , 33 ]. In contrast, the pupal parasitoids Trichopria drosophilae (Perkins, 1910) (Diapriidae), Pachycrepoideus vindemmiae (Rodani, 1875), Spalangia erythromera Forster, 1850 and Vrestovia fidenas (Walker, 1848) (all: Pteromalidae) were able to successfully parasitize D. suzukii [ 30 , 32 , 34 ].…”

(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.
