Confirmed and potential wild hosts of the Spotted wing drosophila (Drosophila suzukii) in Slovenia

The spotted wing drosophila (Drosophila suzukii (Matsumura)) is a highly invasive species and attacking different species of berry carrying hosts. Much research has already been done on the crop hosts over the world and in Slovenia, but for wild hosts less is known. On basis of literature and fieldwork we prepared a list of potential and actual known species of wild hosts for Slovenia. In 2019, berries of different species were collected and D. suzukii was either reared from these berries or berries were dissected. In total we found in the literature for Europe 99 species which were used as host for D. suzukii. For Slovenia we found 71 potential hosts and 14 hosts which were actually infested. in Slovenia there was a broad range of potential hosts from 41 genera. The genera with the most potential hosts were Prunus, Lonicera and Vaccinium. Among the potential hosts were also many species which were invasive alien or alien species. The list was discussed in the context of management implications and further research on D. suzukii in Slovenia.Plodova vinska mušica (Drosophila suzukii (Matsumura)) je invazivna tujerodna žuželka, ki napada številne rastline s sočnimi plodovi, zlasti jagodičje. Narejenih je bilo že veliko raziskav v povezavi z gostitelji D. suzukii, ki so gojeni kot ekonomsko pomembne kmetijske rastline, malo pa je znanega o divje rastočih, t.j. negojenih gostiteljih te vrste. V naši raziskavi smo na podlagi pregleda literature in lastnih raziskav izdelali seznam potencialnih in znanih divjih gostiteljev plodove vinske mušice v Sloveniji. V sezoni 2019 smo nabrali plodove različnih vrst divjih gostiteljev, ki smo jih v laboratoriju analizirali na prisotnost D. suzukii. Literatura navaja, da je v Evropi 101 vrsta rastlin primerna kot gostiteljska za D. suzukii. Od teh je v Sloveniji prisotnih 72 vrst, ki spadajo v 41 rodov. D. suzukii je bila pri nas potrjena na 16 vrstah . Najpogostejši gostitelji plodove vinske mušice v Sloveniji so iz rodov Prunus, Lonicera in Vaccinium. Med potencialnimi divjimi gostitelji za D. suzukii v Sloveniji so tudi rastline, ki so tujerodne ali invazivne tujerodne vrste. Članek obravnava seznam divjih gostiteljev plodove vinske mušice v Sloveniji v luči iskanja novih načinov zatiranja plodove vinske mušice in daje smernice za nadaljnje raziskave na tem področju
