Biodiversity of aquatic insect and physico-chemical water quality parameters in the Bekarbandh pond was assessed during June 2016 to May 2017. Seven sampling stations, each 100m long were established. Three replicates of samplings by aquatic D frame net were used at sampling sites. A total of 4,257 individual of aquatic insect were collected during one year. 6 orders & 12 families were recorded in this study. The family Hydropsychidae and Chironomidae were the most abundant of aquatic insects that was found in the pond water. The CCA revealed the family Mesoveliidae and Chironomidae were correlated with alkalinity in the pond water, whereas dissolved oxygen was correlated with family Baetidae, Coenagrionidae, Hydrophilidae and Helotrephidae. Signs of increasing water quality deterioration were evident in the result of the physico-chemical analyses.
