One of the parasitic species for the aphids present on tomato plants are the braconid wasp called Lysiphlebus fabarum (Braconidae: Hymenoptera: Insecta). The purpose of this scientific paper is to determine whether these wasps can be a way of reducing the population aphids. Tomato plants typically attract many harmful aphid species. It is known that aphids are the most common dangerous species with a high number of generations, and generally difficult to control. Observations were conducted under laboratory conditions in Uzbekistan. The study of the efficacy of Lysiphlebus fabarum on aphids shows that parasite entomophagus can provide a reduction in the number of aphids in tomatoes, even at a ratio of 1:20, their biological efficiency being approximately 50%, and in the ratio of 1: 5 and 1: 10 is about 90%.
