abstract
An investigation was carried out to study of the aquatic entomofauna distribution Kondakarla lake from July 2012 to June 2014. A total 1227 individuals under 27 families and 51 taxa in seven orders were recorded. The aquatic insects were sampled systematically and randomly in station-wise habitats, using the standard protocols. Among the collected insects Order Hemiptera was dominant with 10 families which contributed to 37.04% of the total texa followed by Coleoptera, Ephemeroptera and Odonata each contributed to14.82%, Diptera and Trichoptera 07.41% and Megaloptera 03.70%. The percentage of taxa in an order Hemiptera dominant with 33.33% followed by families Coleoptera 25.49%, Odonata 23.53%, Ephemeroptera 07.84, Diptera and Trichoptera 03.92% and Megaloptera 01.96%. The month wise entomofauna population density calculated by using PAST diversity index from the number of population was represented at Kondakarla lake.
