“…Regardless, our statistical analysis provides conservative results as these individuals increase the variability of our data. Our results contrast with the prediction of the daily difference of activity between the two species, although we know that D. suzukii and D. melanogaster can be in sympatry on the same fruits (Dancau et al, 2017;Hennig and Mazzi, 2018;Mitsui et al, 2006Mitsui et al, , 2010Poyet et al, 2014;Shaw et al, 2018a;Stemberger, 2016). Unexpectedly, we did not find any thermal conditions under which D. suzukii was active at a different time from D. melanogaster (Fig.…”

“…Unlike other Drosophila species, D. suzukii is able to oviposit eggs in ripening, healthy fruits (Lee et al, 2011) using its serrated ovipositor (Atallah et al, 2014). However, adult emergence was observed in the field from the same rotting fruits as other Drosophila species (Dancau et al, 2017;Hennig and Mazzi, 2018;Mitsui et al, 2006Mitsui et al, , 2010Poyet et al, 2014;Shaw et al, 2018a;Stemberger, 2016), thus revealing conditions of sympatry. Moreover, laboratory studies suggest that D. suzukii is a weak competitor compared with other European Drosophila species (e.g.…”

Phenotypic plasticity may contribute to the invasive success of an alien species in a new environment. A highly plastic species may survive and reproduce in more diverse environments, thereby supporting establishment and colonization. We focused on plasticity in the circadian rhythm of activity, which can favour species coexistence in invasion, for the invasive species Drosophila suzukii, which is expected to be a weaker direct competitor than other Drosophila species of the resident community. We compared the circadian rhythms of the locomotor activity in adults and the expression of clock genes in response to temperature in the invasive D. suzukii and the resident Drosophila melanogaster. We showed that D. suzukii is active in a narrower range of temperatures than D. melanogaster and that the activities of the two species overlap during the day, regardless of the temperature. Both species are diurnal and exhibit rhythmic activity at dawn and dusk, with a much lower activity at dawn for D. suzukii females. Our results show that the timeless and clock genes are good candidates to explain the plastic response that is observed in relation to temperature. Overall, our results suggest that thermal phenotypic plasticity in D. suzukii activity is not sufficient to explain the invasive success of D. suzukii and call for testing other hypotheses, such as the release of competitors and/or predators.

“…A recent study by Dancau et al 24 investigated whether the direct exploitative competition from D. melanogaster could suppress D. suzukii numbers at various densities in mixed culture settings over multiple generations. In pairwise, small group and cage settings, they also found that the presence of D. melanogaster significantly reduced adult D. suzukii emergence in no choice experiments.…”

“…To date, we do not know if these co-occurrences lead to interspecific competition or other types of interactions. However, as part of the investigations into the ecological impacts of D. suzukii in the invaded areas, such a result clearly suggests it will be necessary to pay more attention to these species that have been neglected with regard to D. melanogaster [ 20 , 28 , 29 ]. Indeed, even if Ds does interact with D. melanogaster / D. simulans (see for instance the “vineyard” case-study: [ 18 , 19 , 20 ]), it seems that most of the regular resources for D. melanogaster / D. simulans , whether natural (e.g., fallen fruits) or artificially introduced (e.g., banana-filled traps), are probably not the most suitable for this species.…”

The spotted wing Drosophila, Drosophila suzukii (Ds), became a major economic pest for fruit production since its establishment in Europe and America. Among potential control methods, only classical biological control appears to be a mean of sustainably regulating Ds in both cultivated and natural habitats. In the frame of risk assessment, pre-release surveys were carried out in a restricted but highly heterogeneous area in the south-east of France using traps and deliberate field exposures of Ds and D. melanogaster larvae/pupae. Although Ds abundance varied according to sampling methods, it was found to be pervasive and to produce offspring and adults in most conditions (spatial and seasonal). Its main limits are some specific abiotic conditions (i.e., desiccation) as well as interspecific competition. Indeed, Ds mostly co-occurred with D. busckii and D. hydei, probably due to common phenology and/or ecological requirements. These two species thus deserve more attention for risk assessment. The main indigenous parasitoids collected belonged to two pupal species, Trichopria cf drosophilae and Pachycrepoideus vindemmiae, but their presence was observed late in the autumn and mainly in cultivated areas. Results are discussed in a comparison of the methodological approaches for monitoring Drosophilids and the benefits-risks assessment of classical biological control.
