The present study deals with the aquatic insects survey conducted from February 2016-May 2016 in three permanent ponds of Guwahati city, Assam. This study enumerated 25 different species belonging to 6 orders and 13 family. Order Hemiptera represent the highest number of species (15 species) followed by Coleoptera (4 species) and other orders such as Odonata (2 species), Hymenoptera (1 species), Ephemeroptera (1 species), and Diptera (2 species). In the present study order Hemiptera was found most diverse and relatively abundant in the pond. Overall species abundance and richness revealed that insect order Hemiptera were the most dominant and that of Hymenoptera was the least dominant in the three pond system. In this study, Coleoptera was the second dominant order and Ephemeroptera and Hymenoptera was the least dominant order which suggested that the study area of Guwahati city is less polluted and rich in aquatic vegetation. The Shannon-Weiner diversity index for aquatic insect remained above 3.0 indicating the good quality of the water. The values of Shannon diversity index at three pond system Jorpukhuri, Dighalipukhuri and Silpukhuri is 2.4894, 2.0886 and 1.4678 respectively. The Simpson values for richness and evenness of the three pond Jorpukhuri, Dighalipukhuri and Silpukhuri is 0.906, 0.9 and 0.82 respectively.Pages: 271-275 | 1267 Views 64 DownloadsDownload Full Article:
