Abstract

This study was conducted during 2019-20 at IPEE RAS (Moscow, Russia to study the insectocompost formed as a result of the development of the black soldier fly Hermetia illucens larvae on various organic substrates, on nematodes of various trophic groups). The analysis of the nematode community forming during cultivation of the lawn grass with the introduction of insectocompost, allowed to reveal a significant increase of bacteriophages, polyphages and predators, and the dominance of bacteriophages in the community structure. The inhibitory effect of a number of insectocomposts on the rootknot nematode in the tomato -Meloidogyne incognita model system was shown. Research results have proven the effectiveness of this insect compost not only as an organic fertilizer, but also as a means of limiting the development of harmful plant-parasitic nematodes and as an instrument to regulate the numbers of the nematode populations.
