Trichopria drosophilae (Diapriidae) and Leptopilina heterotoma (Figitidae), native parasitoids of Drosophila suzukii, confirmed in Slovenia | Trichopria drosophilae (Diapriidae,) in Leptopilina heterotoma (Figitidae) - prvi najdbi domorodnih parazitoidov plodove vinske mušice (Drosophila suzukii) v Sloveniji

Inglés. 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).

Esloveno. Plodova vinska mušica (PVM), Drosophila suzukii (Matsumura, 1931) (Diptera, Drosophilidae) je bila prvič ugotovljena v Sloveniji jeseni leta 2010. Kmalu po tem se je izkazalo, da gre za enega najpomembnejših škodljivcev pri pridelavi jagodičastega in koščičastega sadja pri nas in drugod po svetu. V okviru programa strokovnih nalog s področja zdravstvenega varstva rastlin, natančneje v okviru naloge inventarizacija koristnih organizmov za biotično varstvo rastlin, smo v letu 2018 ugotavljali zastopanost domorodnih vrst parazitoidov plodove vinske mušice. Kot vabe za lovljenje parazitoidov PVM smo uporabljali koščke banan okužene z ličinkami in bubami PVM, katerim smo dodali umetni jabolčni medij za vinske mušice. Ugotovili smo, da sta pri nas zastopana larvalni parazitoid Leptopilina heterotoma (Thompson, 1862) (Hymenoptera: Figitidae) in parazitoid bub Trichopria drosophilae (Perkins, 1910) (Hymenoptera: Diapriidae). Obe vrsti sta bili ugotovljeni avgusta leta 2018 v osrednji Sloveniji z vabami nastavljenimi v grme malin.
