Trichopria drosophilae (Diapriidae) and Leptopilina heterotoma (Figitidae), native parasitoids of Drosophila suzukii, confirmed in Slovenia
Špela MODIC | Primož ŽIGON | Jaka RAZINGER
The Spotted-wing drosophila (SWD), Drosophila suzukii (Matsumura, 1931) (Diptera, Drosophilidae) was recorded for the first time in Slovenia in autumn 2010. Shortly thereafter, it turned out to be one of the most important insect pests of soft and stone fruit in Slovenia and elsewhere. Within the expert work in the field of plant protection, more precisely within task inventarisation of beneficial organisms for biological control, the presence of indigenous D. suzukii parasitoids was investigated in 2018. Sentinel traps baited with D. suzukii larvae and pupae in banana slices enriched with artificial food medium for drosophilids were used for inventorying D. suzukii parasitoids in raspberries. The pupal parasitoid Trichopria drosophilae (Perkins, 1910) (Hymenoptera: Diapriidae) and the larval parasitoid Leptopilina heterotoma (Thompson, 1862) (Hymenoptera: Figitidae) were recorded parasitizing D. suzukiifor the first time in Slovenia in August 2018 in Central Slovenia (Ljubljana).
