Abstract
Chironomid larvae were studied at selected river sites in the Radika River catchment to identify the
indicator taxa and analyze their contribution to the assessment of the ecological quality of the rivers
included in the planned reservoir "HPS Boshkov Most". Quantitative macroinvertebrate samples were
collected in six rivers along the Radika River watershed (Mala River, Lazaropolska River, Garska River,
Rosocka River, Tresonecka River, and Jadovska River) in two seasons (Summer and Autumn, 2012) using a
Surber sampler. Chironomids were identified to the genus or species level. We found a total of 11 taxa of
the chironomid larval fauna belonging to 4 subfamilies: Chironominae, Tanypodinae, Orthocladiinae, and
Prodiamesinae, in which indicators of high/good quality, e.g. Prodiamesa olivacea (Meigen, 1818) were
noted. The most abundant subfamily was Orthocladiinae with a total of 5 taxa. Among the recorded taxa
the most widespread species was Polypedilum pedestre (Meigen 1830) (all 6 sites), followed by
Paratendipes sp., Prodiamesa olivacea, Eukiefferiella quadridentata Cernovskij, 1949, E. longicalcar
Thienemann, 1926 and Thienemannimya sp. (at 5 sites); where the least recorded taxa (at 4 sites) were E.
alpestris Goetghebuer, 1941 and E. longipes (Staeger, 1839). Concerning its abundance, the most common
chironomid species was E. longicalcar together with Rhithrogena gr. semicolorata (Ephemeroptera) and
Ancylus sp. (Gastropoda) from Jadovska River. In conclusion, we can emphasize that the overall
composition of the recorded indicative chironomid species can serve as good indicators for the future
conservation of the pristine environment and can contribute to the further conservation of the Radika
River watershed.
