[Blood-sucking midges of the floodplain of the Sylva River (Ceratopogonidae)].

21 species of bloodsuckling midges were recorded from the Kishert region of the Perm district. During the period of investigation the group obsoletus was most abundant, then the group pulicaris and fascipennis. There was noted a poor adaptation of midges to different biotopes and high ecological plasticity of mass species. Specific composition of midges attacking man and domestic animals is more diverse as compared to species attacking birds. Food specialisation is more distinct in ornithophilous species.
