Among vegetable plants grown indoors, cucumber is one of the main ones. In the structure of production, the area allotted for it is 60-70%. This is due to the fact that it provides a high yield compared to other vegetable plants, is capable of producing fruits for fresh consumption in low light conditions already 8-9 weeks after germination, which contributes to the provision of fresh fruits to the population in the winter-spring period. vegetable products, when its lack in people's  nutrition is especially acute. In addition, its fruits are easily absorbed by the body, as a result of which they are widely used in cooking as a dietary food. Favorable climatic conditions of closed ground, namely high temperature and humidity, favor the development of phytophages. This article confirms the feasibility and effectiveness of protecting greenhouse cucumber plants from pests. The highest yield - 36.5 kg / m2 was observed in the variant with the use of the drug Confidor 200 SL, r.c., which is 6 kg / m2 higher than in the control.In the variant with the use of the drug Actellik 500 EC, c.e. - 35.5 kg / m2, and using the biological preparation Aktofit, c.e. - 34.8 kg / m2, which is respectively 19.7 and 18.1% higher than in the control, where the average yield during the study period was 30.5 kg / m2. Based on the generalization of the obtained research results in specific production conditions, to obtain high yields and control the number of cucumber pests such as spider mites, greenhouse whiteflies and aphids in a greenhouse, it is recommended to use Aktofit preparations, c.e. at the rate of 2.0 l/ha, or Confidor 200 SL, r.k. - 0.25 l/ha, which will provide crop protection and a level of profitability at the level of 43.3-42.7%.
