Population of vinegar fly Chymomyza amoena (Loew 1862) in orchard in the Međimurje area

Abstract

Dinamika leta strane vrste Chymomyza amoena istraživana je u mješovitom voćnjaku na lokalitetu Mursko Središće tijekom 2017. godine pomoću dvije vrste hranidbenih lovki (na bazi jabučnog octa i fermentiranog voća). Prisutnost vrste utvrđena je pomoću lovke na bazi jabučnog octa no u vrlo niskoj brojnosti. Na lovki na bazi fermentiranog voća vrsta C. amoena nije ulovljena. Ukupno je ulovljeno 635 jedinki octenih muha a 107 jedinki pripadalo je invazivnim vrsta. U voćnjaku Mursko Središće zabilježena je dominantnost vrste Drosophila suzukii (104 ulovljene jedinke) te je utvrđena prisutnost vrste Gitona distigma. Nalaz vrste G. distigma prvi je pronalazak vrste na području Međimurja. Rezultati ovog istraživanja prilog su istraživanju rasprostranjenosti vrste C. amoena na području Međimurja.The flight dynamics of alien species Chymomyza amoena was investigated in mixed orchard Mursko Središće by using two kinds of feeding traps (based on apple vinegar and fermented fruits) during 2017. The presence of C. amoena was recorded on apple vinegar trap but in very low numbers. Species C. amoena wasn't caught on fermented fruit trap. A total of 635 specimens of drosophilids were caught and 107 individuals belonged to invasive species. In orchard Mursko Središće the dominance of species Drosophila suzuki (104 specimen caught) was recorded and the presence of species Gitona distigma was determined. The finding of species G. distigma represents the first finding of this species in Međimurje area. This results represent contribution to the study of the distribution of species C. amoena in Međimurje area
