Drosophila suzukii (Matsumura) is a particularly dangerous species of tree fruit and berry fruit species in Europe and all over the world. It was first reported in 2014 in the regions of Blagoevgrad, Kyustendil, and Plovdiv in Bulgaria. Its harmful activity directly threatens the yield and in some years it can compromise the harvest. The present study aims to monitor the population density and fruit damage to blackcurrant fruits of the 'Titania' variety. The studies were conducted in the period 2019-2020 at the Research Institute of Mountain Stockbreeding and Agriculture of Troyan. Insect traps were used for monitoring, which were placed at the beginning of fruit ripening. As a result of the conducted observations, it was found that the spotted wing drosophila appeared at the beginning of fruit ripening, and its peak was reported during large-scale fruit ripening.
