General view of the external morphology of the four most abundant species: D. melanogaster (a), D. simulans (b), D. subobscura (c) e D. Suzukii (d) males. Sexual dimorphism is evident in D. suzukii males (d) and D. Suzukii females (e): the black spots on the wings (d), the two sets of black sex combs on the foretarsi (g) in males and the serrated ovipositor in females (f).
In Puglia, D. suzukii could attack a series of important crops - such as cherries and grapes - which are essential for the region's economy. A constant monitoring of invasive species is essential to support a suitable risk management and avoid yield losses not only in Puglia but also in other Mediterranean regions with similar environmental, climate and productive conditions.
