Ecology of Preimaginal Stages of Blood-Sucking Black Flies in Central Non-Chernozyom Zone of the Russian Federation

Abstract

Species composition of black flies pre-imago stages was investigated in different types of inland waters (large, middle and small rivers, brooks and reclamation channels of Moscow, Ryazan and Tver regions). There were found 9 species of Simuliidae in large rivers, 12 -in middle rivers, 14 -in small, 10 -in reclamation channels. Larvae and pupae inhabit coastal area on hydrophytes, rocks, water objects, etc. Dominant, subdominant and scanty black flies species were discovered. Maximum of population density was registered in the late May -early June and was up to 700 flies per 1 dm 2 in average.
