A current study was examined in aquatic insects as a bioindicator of water quality of perennial river Tamirabarani. Aquatic insects were sampled total of 6570 individuals belonging 26 families from 11 orders during the study period of 2016 to 2017. The study revealed most aquatic insects were recorded maximum in Gadananathi (753 individuals) and the minimum in Authur (82 individuals). The standardized methods were used to estimate the physico-chemical parameters of the responsible study site. The correlation coefficient analysis of Bivariate Pearson correlation and 2-tailed flag was performed Water quality parameters showed significant (positively correlated value) at the 0.01 level was found between the physic-chemical parameters values. The diversity indices discussed, that is to influence environmental variability in the diversity and distribution of aquatic insects. The biotic indices of FBI (Family biotic indices), BMWP (Biological monitoring working party) and ASPT (Average score per taxon) scores exist in Good, Fair and Poor water quality of river Tamirabarani.
