Abstract :The study\'s objective was to evaluate how the capture rate of bottle traps is influenced by their color, number of entry holes, and bait liquids.For this purpose, yellow, blue, green, red, black, white, and transparent (colourless) traps were tested. Apple cider vinegar, grape vinegar, white wine, yeast, and water (control) were used as bait liquids. The number of entry holes was 2, 4, 6, and 8 holes per trap on the side of the bottle traps. The experiments were conducted in a randomised block design with three replicates in a fig orchard (variety Bursa Siyahı) with 437 trees in Aydın province from September 2018 to March 2019. In total, 48 traps were mounted on the experimental trees (1 trap per 1 tree), and counting of the drosophilid individuals in the traps was performed weekly. Red-coloured traps attracted the highest number of drosophilid individuals, followed by yellow-coloured. Regarding different baits, grape vinegar attracted the most drosophilid individuals, followed by white wine. Concerning the number of trap entry holes, the highest number of individuals were caught in traps with the highest number of holes, 8. In all traps, Zaprionus tuberculatus Malloch, 1932 was the species caught in the highest numbers, followed by Drosophila subobscura Collin, 1936 and Drosophila suzukii (Matsumura, 1931). Z. tuberculatus was mostly caught in traps containing grape vinegar, while D. subobscura and D. suzukii were mainly caught in traps containing white wine. In our study, the red-coloured traps containing vinegar with 8 entry holes were the most effective in monitoring drosophilid populations.
