Faunistic study of Chironmidae in the Hablehrood River

Chironmidae is one of the zoo-ecological unique group in the aquatic ecosystem. These insects are among the frequent larvae in shallow areas of the lakes, pools and road which has a dense cover of aquatic plants. This study was conducted to identify the Chironomidae living in Hablehrood stream. Sampling programmed seasonally for four selected pilots (Zarrindasht, Simindasht, KHomadeh and Enzaha) by dredge in three replications for each pilot in 2015. Samples were transferred in ethanol 70% to the laboratory. In the laboratory, larvae were separated from other substrate elements, after calcifying the samples, they were permanently fixed. Identification was done by use of available keys to genus level. The result showed that three genus hironomus, Polypedilum and Stritochironomus belonged to sub-family Chironominae were collected from Hablehrood.
