Current study was carried out in a community pond located in lower Irongmara, Barak Valley, Assam. Water of the pond is regularly utilized for domestic purpose, fish culture and rarely for drinking purpose. Present study reported aquatic insect order Hemiptera as the only order throughout the year. Among Hemipterans, family Notonectidae showed highest relative abundance (97%) followed by family Gerridae (3%). Neogerris parvula Stål, Anisops barbata Brooks and Enitheres fusca Brooks are the aquatic insect species recorded from the pond. Except concentration of Phosphate, all other physic-chemical parameters were found within permissible limit. Shannon Diversity index values, ASPT, SPI , BWMP score of pond suggest, despite good ecological potential human induced activities are responsible for degradation of habitat quality. Biological monitoring of any water body using different biotic scores along with physico-chemical analysis of water quality can display total health status of a particular water body.
