Резюме: Syrphid flies are important for biological control in agroecosystems. The aim of the study was to acquaint the aphidophagous species from family Syrphidae (Diptera) in oriental tobacco, their density and dynamics of development depending on density of Myzus persicae Sulzer (Hemiptera; Aphididae). During two years research were identified four species of flies from the family - Episyrphus balteatus De Geer, Scaeva pyrastri L., Sphaerophoria spp. and Syrphus ribesii L. The syrphids with highest density are E. balteatus and S. pyrastri, 35.7% and 26.8% of the total number of representatives in tobacco cenosis. Syrphid flies appear during the multiplication of aphids and remain in tobacco cenosis after their reduction begins. In 2021, the highest density of flies was found in the first and second ten days of July, and in 2022 in the second and third ten days of June, when the density of M. persicae was greatest.
