Variation in aquatic Insects community in a tropical water body on account of anthropogenic activity


Nisar Ahmad Ganie, Rajni Raina, Ashwani Wangneo

Present work conducted on the upper lake regarding variation in aquatic insect diversity on account of anthropogenic activity revealed a total of 17 different species during premonsoon season. These 17 species of aquatic insects belonged to 6 orders and 17 different families with Coleoptera being the most dominant order while, Ephemeroptera and Megaloptera being the least dominant. Maximum number was recorded during the month of March associated with rich submerged vegetation (mostly with Ceratophyllum, Najas and Potamogeton). Anthropogenic activities and lake deweeding process disturbed the habitat and rendered oviposition sites of aquatic insects which reduced their diversity greatly.
