Özet
The roles of larval chironomids in the food chain of both the lotic and the lenticecosystems are very important. On the one hand, chironomid larvae feeding onalgae, diatoms, rotting organic matter, plant, and animal residues also play animportant role in these systems as a source of food for other carnivores andomnivorous organisms. In this study, the gut contents of Cryptochironomusdefectus (Kieffer, 1913), Cladotanytarsus mancus (Walker, 1856), Polypedilumscalaenum (Schrank, 1803), Tanypus kraatzi (Kieffer, 1912) collected from thefreshwater ecosystems located in the northern parts of the Thrace region of Turkeywere analyzed to compare their feeding habits. As a result of the analysis, it wasdetermined that while plant fragments were dominant in C. defectus species in thegut content (44.3%), algae were dominant for C. mancus (44.7%), P. scalaenum(63.5%), T. kraatzi (65%). According to the results of the Shannon-Wiener (H')index species, diversity of the P. scalaenum was found to be the highest amongthe larvae (H'= 1.345). Also, according to the Bray-Curtis similarity index, themost similar types of gut contents were P. scalaenum and C. defectus (38%). Thislow rate indicated that the species have different food preferences
