The article discusses some aspects of plant protection biologization as a leading trajectory in the development of the globalgreen economy. The article presents the trajectories of increasing the number of beneficial insects in the framework of biologicalplant protection as one of the most important aspects for reducing the pesticide load on farming ecosystems. To increase thebiodiversity and abundance of beneficial species of entomofauna in farming ecosystems that provide stabilization and thepossibility of self-regulation of entomocomplexes, it is recommended to reduce chemical treatments of crops by switching fromcontinuous field treatments to local, point-based as well as the use of edge treatments, selective preparations. It is shown that thedifference in the structure of crop rotations of perennial grasses leads to optimization of the ratio of the number of phyto- andentomophages in crop rotation due to active migrations of beneficial entomofauna. The article presents the results of field studieson increasing the relative abundance of entomophages and parasitic insects in crop rotations with the presence of perennialgrasses in comparison with crop rotations involving only row crops. The author highlights the importance of creatingentomological sanctuaries to increase the potential of entomophages, parasitic insects, and pollinators.
