Sažetak
The vinegar flies (Diptera: Drosophilidae) were identified as pests in grape and wine production since they often appear in vineyards and wine cellars. The most well-known species from this family is Drosophila melanogaster, which transmits bacteria responsible for acidic rot of grapes. Affected grapes have acetic odour, and vinification is often impossible. The species composition of vinegar flies was not clearly known in Croatia until 2010, when the invasive Drosophila suzukii was found and then the research of drosophilids was intensified. Drosophila suzukii attacks ripening fruit and can cause economic damage to grapes and finally wine production. Populations of drosophilids have never been investigated in vineyards of Zagrebačka county, and the status of D. suzukii in this wine growing area was unknown. The main aim of this research was the monitoring of alien species of drosophilid flies in the vineyards of the experimental field “Jazbina” (Faculty of Agriculture). Drosophilids were collected from March until October of 2017 by using traps based on apple vinegar. Altogether 121 specimens belonging to five species (D. suzukii, D. melanogaster, D. hydei, D. busckii and Chymomyza amoena) from two genera were identified. Alien species represented about 30% of the total number of collected drosophilids. Among alien species the polyphagous pest D. suzukii was the most abundant one, which poses a serious threat to grape production in the studied field “Jazbina”. Findings of alien vinegar flies represent the new records of these species in the area, and contribute to the knowledge of drosophilid flies in Croatia.
