First report of the invasive pest Drosophila Suzukii (Matsumura, 1931) (diptera drosophilidae) on Olea Europaea L. in Italy

The fruit crop pest Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae) is a highly polyphagous invasive pest listed in the EPPO A2 list. This species has been reported as host of a variety of cultivated plants and wild fruits. Herein, we report the record of some D. suzukii viable specimens that were found in olives directly collected from the tree branches in four different sites of Latium and Umbria (Italy). Adults emerging from these pupae were collected and morphological and molecular analysis were carried out to confirm the species identity. Olive tissues alterations were observed in association with the presence of the species. The analysis of the available literature showed us that this is the first record of D. suzukii as a phytophagous species on the olive tree in Italy and probably worldwide.
