Trichoptera (Arthropoda: Insecta) fauna of the Black Sea region

In this study, 1021 individuals were collected from 24 stations by seasonal periods between May 2014 and October 2015. Individuals were examined and diagnosed at species level. As a result of the research, 8 familia and 20 species belonging to the Trichoptera in the Black Sea Region were determined. Samples were taken with Kick Sampling Method. Benthic samples were taken with scooping by hand for 5 minutes at pre-determined 24 stations. Sampling for quantitative analyzes was performed in 3 replicates. It has been observed that temperature, pH and dissolved oxygen values are the determining factors in the taxon diversity of measured water parameters. As a result, 20 species and 1021 individuals belonging to 8 Familia (Hydropsychidae, Rhyacophilidae, Ecnomidae, Psychomyiidae, Polycentropodidae, Molannidae, Philopotamidae and Limnephilidae) were determined. Hydropsyche angustipennis was found to be the most dominant species with a rate of %42,02, while Polycentropus flavomaculatus, Wormandia subnigra, Molanna angustata and Ecnomus tenellus were found to be least dominant species with %0,1. Of the detected species, 8 are new registrations for some stations. Key words: Black Sea, Trichoptera, seasonal distribution, water quality, biological indicator.
