The spread of Drosophila suzukii (Matsumura, 1931) in northwestern Croatia

The spotted wing drosophila (Drosophila suzukii), native to Asia, is an economically important pest of thin and soft fruit skin crops. It was introduced to Europe in 2008 and is rapidly spreading across the continent. The pest is extremely fertile, has a wide range of host plants and high dispersal potential therefore it represents a serious threat to European fruit production. In Croatia the pest was first reported in 2010 in the eastern part of country (Istria County) on raspberry (Rubus idaeus), peach (Prunus persica) and grapevine (Vitis vinifera) and since then has spread across the coastal region and on northern counties (Međimurje and Koprivnca-Križevci County). The major detected host plants in Croatia are cherries (Prunus cerasus and Prunus avium), peach, apricot, nectarine, plum, berries (Rubus spp. and Fragaria spp.), fig and grapevine. In 2016 the presence of pest was confirmed in Zagreb County for the first time on strawberry where economic damages in production were observed, so the spread of D. suzukii in Croatia continues. In addition to the mentioned hosts, apple (Malus domestica) was detected as a newly discovered host plant in Međimurje County.
