In order to fulfill this task, the object of the study was the main pest of the Nur-Sultan greenhouse, the mealybug and the dynamics of its population development. The study revealed the annual and seasonal dynamics of the number of mealybugs and traced the sequence of alternation of ornamental plants with phytophages throughout the year. To assess the pest's resistance to biological control, two biopesticides were taken. These are: "Bona Forte Spray" on a natural pyrethrin basis and " Phytoverm " on the basis of aversectin - C.
