“…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.…”
