Sažetak
Drosophila suzukii (Matsumura, 1931), native to Eastern and South-eastern Asia, nowadays has spread across North America and Europe. This Dipteran species is an invasive pest that causes economic damages due to its infestation on different fruit crops. It was first reported in Croatia in 2010 across various fruit orchards in Istria, and since then, it has spread across the country’s territory including the capital city Zagreb and the Dalmatian region. In this study, we report the record of D. suzukii from an olive orchard in Zadar County, Croatia, with integrated pest management (IPM) system, surrounded by autochthonous sour cherry var. Marasca (Prunus cerasus var. marasca. To monitor the presence and abundance of flying pests, yellow sticky traps were set up from mid-July to late September 2018 and September and October 2019, within two olive orchards. Additional sampling for biodiversity assessment was done using a beating stick with a net. Examination of yellow traps did not confirm the presence of this invasive pest species. On the other hand, the DNA barcoding method of individuals sampled with a net confirmed the presence of D. suzukii. Earlier research in the area confirmed spider predation on Bacterocera olea, common dipteran pest species. Following mentioned results, we applied gut content analysis using e-DNA method to see potential biocontrol on D. suzukii. Here we present the result of gut content analysis of common predators for biocontrol of D. suzukii. The spread of this invasive fruit pest demonstrated the need to further research and implement environmentally friendly and sustainable pest control within agroecosystems, including biocontrol.
