Abstract: The aim of the study was to analyze the behavior of Myzus persicae Sulzer towards two types of tobacco – oriental (ecotype Dupnitsa - variety Dupnitsa 733) and Virginia (L 0842) in seedling production. The occurrence of aphids was almost identical for both years for both types of tobacco. In 2021 it was registered on May 5th, and in 2022 on May 3rd. By the end of the first ten days of May, an increase in the density of M. persicae was recorded in both types of tobacco, after which a reduction of the pest was recorded. No difference was reported in the density and dynamics of aphids for the two years for the individual types of tobacco, but higher densities and dynamics of M. persicae were recorded in Virginia (L 0842) tobacco compared to oriental (ecotype Dupnitsa - variety Dupnitsa 733) in each individual year, as well as for both compared years together.
