A Study on the Diversity of Aquatic Insect Communities of Kaliabor Subdivision, Nagaon, Assam

Aquatic insects holds an important place in the ecology of freshwater ecosystem. The present study deals with the aquatic insects survey conducted from January 2018-March 2018 in three permanent water bodies of kaliabor, Nagaon district, Assam. During the study all total 28 species of aquatic insects have been recorded belonging to six order and 18 family. Different group of insects have different tolerance to the quality of the water in which it lives. Due to the diversity of insects, each different group relies on a different set of conditions in order to survive. According to this study order Hemiptera represents the highest number of species (Nine families including 15 genera). Coleoptera (three families including four genera.), Odonata (two families including four genera) Diptera(two families including two genera) Ephemeroptera (one family including two genera), Hymenoptera(one family including one genera) were recorded during this work. Water quality parameters in the three sites don't show significant differences. Dissolved oxygen is found to be highest in Solong beel and also the total number of insects species present are high at this site followed by Kolong river and Jaysagar doloni.
