Abstract: This study aimed to determine diversity and abundance of aquatic insects in a protected forest fishpond. Sampling was done monthly between December 2007 and November 2008. In the pond, water column and sediment were collected using a hand-net and a van Veen grab respectively. A total of 13,469 individuals distributed among 24 families belonging to 7 orders were recorded. Heteroptera recorded the highest number of taxa. Taxa richness ranged from 17 (Site B) to 24 (Site A). Heteroptera and Diptera were found to be the most abundant in the pond. Notonectidae and Chironomidae were the most abundant family in order Heteroptera and Diptera respectively. Shannon-Wiener diversity index, Evenness and Margalef index were higher at Site A. This study revealed that water of the pond is slightly polluted as supported by the values of biological indices and by presence of insect of orders Heteroptera and Coleoptera.
