Abstract :

 The present study was conducted to assess the five different sites of Loktak Lake insect communities through the determination of aquatic insect diversity, abundance, composition and water quality parameters. Water samples and insects were collected from the five different sites of the Loktak Lake of Manipur during March 2013 to Feuary 2014. Correlation between insects species richness with hydrological attributes showed good relationship and water temperature, free carbon dioxide, dissolved oxygen and PH were found the most important variables in shaping the insects assemblage. Altogether, a total of 3278 individuals and 58 insects species belonging to 44 genera, 20 families and 6 orders were recorded to the order Ephemeroptera, Odonata, Hemiptera, Coleoptera, Diptera, and Trichoptera, and order Hemiptera were the most abundance. The chemical properties and distinct taxa found in the water suggest that the water body is not polluted.
