Abstract

Drosophila suzukii (Matsumura, 1931), or spotted wing drosophila (SWD), is a potential threat to both berries and stone fruits. It causes great damage to raspberry, grape and blackberry plantations. The species has a lot of host plants on which it can easily overwinter. Unlike common flies, Drosophila suzukii has a serrated ovipositor. This allows it to infect not only overripe, damaged fruits, but also healthy ones that are just ripening. By pest management it is very important to track the number of pest and its swarming throughout the year. The most suitable are vars traps filled with bait-fluid. At Research Station in Fertőd, we have been monitoring the appearance of the SWD and its number for years. During our tests, we used apple cider vinegar, apple cider vinegar + ethanol, and apple vinegar + ethanol + coffee attractants in our traps. It can be stated that changes in temperature and humidity greatly influenced the catch results. It is typical that most of the individuals of SWD, which appear in the largest numbers in blackberries and raspberries, were encountered in our plantations at the end of August and the beginning of September, the peak being in October.
