To topical selectivity of tachinid (Diptera, Tachinidae) of subfamily Phasiinae in the south part of the Far East of Russia

Tachinid (Diptera, Tachinidae) is a group of Diptera free-living active insects in imaginal stage, and in larval - in parasitizing representatives of 7 orders of insects. Tachinid subfamilies of Phasiinae are specialized vermins of order Heteroptera. The material for the study was the research conducted in various regions of Primorye Territory in the Far East of Russia for the period from 1996 to 2016. Imago of Tachinid flies are immature, and the pref-erence for them of different biotopes is associated with the availability of sources of additional imaginal nutrition, which significantly affects not only females fertility, but also the life span. The source of addi-tional food of Tachinid is flowers nectar, as well as the aphids. Topical selectivity of Tachinid (Diptera, Tachinidae) of subfamily Phasiinae is due to incen-tives associated with fodder plants of adult; with fodder plants of hosts - Hemiptera; directly with host; with host products; trace smells left by other individuals of Phasiinae. The incentives associated with fodder plants of adults and hosts cause the orientation of Phasiinae to certain layers of vegeta-tion: most species occur within 3-4 layers: tall grasses (up to 2 m), medium grasses (up to 1 m), which is explained by the abundance of flowering plants in the zone and its hemiptera population.
