Abstract

Octena mušica ploda, D. suzukii, invazivna je polifagna vrsta iz porodice Drosophilidae. Ovim istraživanjem praćena je dinamika populacije D. suzukii u tri voćnjaka na području Zagreba (Maksimir, Jelenovac, Zelenjak) u razdoblju od 20. ožujka do 27. studenog 2017. godine. Za ulov mušica korištene su hranidbene lovke s jabučnim octom. Let je započeo u razdoblju od 27. lipnja do 11. srpnja te je trajao do 27. studenog. Ukupno je ulovljeno 874 jedinki; u Jelenovcu 187, u Maksimiru 232, a u Zelenjaku 455. Od rujna do studenog zabilježen je kontinuirani let i veliki rast broja ulovljenih mušica zbog čega se pretpostavlja prisutnost više generacija koje se preklapaju. Osim biljaka domaćina, razvoju štetnika na ovom području pogoduju i klimatski uvjeti. Prisutna populacija u gradu Zagrebu predstavlja opasnost za proizvođače voća u okolici Zagreba. Rezultati ovog istraživanja prilog su boljem poznavanju populacije i rasprostranjenosti štetnika na ovom području.

Abstract (english)

The invasive species of Drosophila suzukii, the spotted wing drosophila of the Drosophilidae family is an invasive polyphagous species. In this research the dynamics of the population of D. suzukii was followed in three orchards in Zagreb (Maksimir, Jelenovac, Zelenjak) in the period from March 20 to November 27 2017. Feeding traps with apple vinegar were used for catching D. suzukii. The flight began in the period from 27 June to 11 July and lasted until November 27. The total number of catches was 874; in Jelenovac 187, in Maksimir 232 and in Zelenjak 455. From September to November there was a continuous flight and a large increase in the number of caught flies, from which presume the presence of more overlapping generations. Beside the host plants, the development of the pest in this area is also enabled by suitable climatic conditions. The present population in the city of Zagreb poses a danger to fruit producers in the vicinity of Zagreb. The results of this research are a contribution to better understanding of the population and the spread of the pest in this area.
