Relevance. The introduction of plant protection systems with minimal use of pesticides is one of the main conditions for improving the environment. Phytosanitary construction of agrocenoses is the basis of plant-free plant protection. The creation of agrocenoses with a balanced predatorprey system by stimulating self-regulation mechanisms that create favorable conditions for the accumulation of natural predatory entomophages is a very promising direction in the biologization of plant protection.Methods. For 10 years, the author conducted faunistic studies, identified predatory entomoacarifagi, and showed their regulatory role in the fight against spider mites on grapes. It is established that in addition to the destruction of the spider mite on grapes, predatory mites are able to suppress the number of thrips and whiteflies. The article describes the relationship in the predatorprey system for the predatory tick Amblyseius longispinosus, which is a specialized monophage.Results. Based on many years of research, the regulatory role of the predatory tick Amblyseius longispinosus has been shown. Its high efficiency against spider mites has been proved. 12-15 days with a predator:prey ratio of 1:2, 1:3 and 1:4. Based on sketches and biometric measurements, the morphological description of Amblyseius longispinosus is supplemented. Based on the obtained research results, methods have been developed to create reproducible reserves of the number of predatory ticks in agrocenoses of Dagestan.
