The presence of invasive Drosophila suzukii (Matsumura, 1931) was investigated in three perennial crops (two orchards - Šurdovec and Donje Orešje and one vineyard - Donje Orešje) in the area of Zagreb county. Samples of D. suzukii were collected during the three-month period (from August 18th until November 18th, 2017) by using apple vinegar traps. The presence of D. suzukii was confirmed at all three investigated sites. In the orchard Šurdovec the lowest number (25 specimens) of D. suzukii was caught while the largest number (84 specimens) was caught in the orchard Donje Orešje. In all perennial crops D. suzukii was classified as eudominant species which implicates its invasive character. Sex ratio of D. suzukii at the orchard and vineyard Donje Orešje was female-biased while only in the orchard Šurdovec was male-biased which points to the further spread of the species in the area of Donje Orešje. The results of the research are a contribution to the knowledge of the distribution of this invasive species in the new areas of Zagreb County.; Prisutnost invazivne vrste Drosophila suzukii (Matsumura, 1931.) istraživana je u tri višegodišnja nasada (dva voćnjaka - Šurdovec i Donje Orešje i jednom vinogradu - Donje Orešje) na području Zagrebačke županije. Uzorci D. suzukii skupljani su tijekom tromjesečnog razdoblja (od 18. kolovoza do 18. studenog 2017. godine) pomoću lovki na bazi jabučnog octa. Prisutnost D. suzukii potvrđena je na sva tri mjesta istraživanja. U voćnjaku Šurdovec utvrđen je najmanji broj (25 primjeraka) vrste D. suzukii, a najveći broj (84 primjerka) utvrđen je u voćnjaku Donje Orešje. U svim višegodišnjim nasadima vrsta D. suzukii klasificirana je kao eudominantna, što upućuje na njezin invazivni karakter. U voćnjaku i vinogradu Donje Orešje u populaciji vrste D. suzukii prevladavale su ženke, dok su u voćnjaku Šurdovec prevladavali mužjaci što upućuje na daljnje širenje vrste na području Donjeg Orešja. Rezultati istraživanja prilog su poznavanju rasprostranjenosti ove invazivne vrste na novim područjima Zagrebačke županije.
