Spotted wing drosophila (Drosophila suzukii) – fruit pest

Octena mušica ploda (Drosophila suzukii) štetnik je azijskog podrijetla. Nedavno je introducirana u Europu i jedan je od najvažnijih invazivnih štetnika na voću i grožđu. Istovremeno je unesena i u Sjevernu Ameriku i tamo ima slične posljedice. U Hrvatskoj smo ju registrirali prvi put krajem 2010. na području Istre na malinama, breskvama i vinovoj lozi (Seljak et al., 2011., Masten Milek et al., 2011a, Masten Milek et al., 2011b). Vrlo je vjerojatno da je ona već puno prije bila prisutna u Hrvatskoj, no nije joj se pridavala pažnja, primarno zbog toga što se mislilo da je to vinska mušica (D. melanogaster) ili voćno vinska mušica D. simulans). Helsen (2015) navodi da je octena mušica ploda prvi novi štetnik u voćarstvu u zadnjih stotinjak godina. Octena mušica ploda širi se trgovinom sadnog materijala i plodovima domaćina te letom odraslih kukaca. Danas je u svijetu poznato oko 3000 vrsta iz roda Drosophila. Octena mušica ploda jedna je od dvije iz toga roda koja ima status štetnika (Dreves et al., 2009).Spotted Wing Drosophila (SWD) (Drosophila suzukii) is a pest of Asian origin. It is recently introduced into Europe. D. suzukii is one of the most invasive pests on fruit and grapes. At the same time it is introduced to North America and has similar consequences. In Croatia, we had registered D. suzukii for the first time in late 2010 in Istria on raspberries, peaches and grapevines (Seljak et al., 2011, Masten Milek et al., 2011a, Masten Milek et al., 2011b). It is likely that D. suzukii has been present in Croatia for the long time, but it was not noticed, primarily because of misidentification with species D. melanogaster or D. simulans . According to Helsen (2015), D.suzukii is the first new pest in fruit growing in the last hundred years. Pathway of spreading D. suzuki are plants for planting and fruits of host plants. Today, about 3000 species of the genus Drosophila in known worldwide. D. suzukii is one of two of its species, which has the status of pests (Draves, et al., 2009)
