Nedyalka Palagacheva, Petko Minkov, Vasiliy Dzhuvinov, Diyan Georgiev
Abstract: Drosophila suzukii (Matsumura) is a new serious threat in berry crops. The purpose of the study was to establish its appearance and dynamics of development in one of its preferred nutritional host plants, such as raspberries and blackberries. The surveys were carried out during the period 2016-2017 at the Research Institute of Mountain Stockbreeding and Agriculture in Troyan, in experimental plots with raspberry and the blackberry. The beginning of flying of flies and their population dynamics were followed by the 'Csalomon' (VARL) trap (Hungary). Traps deployed at the beginning of fruit ripening from June to
September. The first caught flies in raspberries and blackberries plantings recorded in June and July, respectively. Registered mean daily temperatures in observed period were 16.6-20.0°C. Gradually the density of D. suzukii increased and its number of caught flies decreased during fruit harvesting.
