ABSTRACT

The present study evaluated the effectiveness of three food trap mixtures in two types of traps, uncoloured and coloured (green base, purple-red, and yellow top), in four different orchard types: blueberry, compost zone, mixed fruit tree, and cherry. The aim was to monitor the viability of the Drosophila suzukii population in these areas. The study covered two years (2020-2021) and the results showed that the mixture of wine and cider vinegar in uncoloured traps (variant V1) captured the highest number of insects, with a total of 32,479 (43% of the total catch). Variant V3 followed with 28,498 insects (38% of the total catch), while cider vinegar alone (variant V2) was less effective, catching 14,731 insects (19% of the total catch). A total of 61,706 Drosophila suzukii were caught in coloured traps over the two years. In this case V3 was the most effective, capturing 41% of the total catch, followed by variant V1 with 39% and variant V2 with 20%. Coloured traps were less effective than uncoloured traps in terms of total catch of Drosophila suzukii. However, in the blueberry orchard in 2021, the coloured traps 1325 captured a higher number of insects than the uncoloured traps. The effectiveness of traps for capturing Drosophila suzukii is influenced by factors such as placement, trap type, components used, timing, and environmental conditions.
