The Fauna of Chironomids and Blackflies (Diptera: Chironomidae, Simuliidae) and Hydrochemical Characteristics of the Hrazdan River (Armenia)

摘要

An annotated list of chironomids (33 species) and blackflies (23 species), identified mainly by their preimaginal phases, is given for the Hrazdan River, Armenia. The list of chironomids comprises five subfamilies: Tanypodinae (1 genus), Diamesinae (1), Prodiamesinae (1), Orthocladiinae (14), and Chironominae (4). The hy-drochemical investigation of the Hrazdan River performed in 2002-2004 showed the water quality to vary between years, seasons, and places.
