They are found associated with water for most part of their life cycle, any change in their number and composition in the population at a given time and space may indicate a change in the water quality. This class has many potential representatives that can be used as environmental bioindicators, among which are from the Coleoptera, Diptera, Lepidoptera, Hymenoptera. Water insects or aquatic beetles are biological indicator. The use of bioindicators is essential for environmental monitoring. In this paper an attempt has been made to focus on the importance of aquatic insects as biomonitors of aquatic ecosystems.

The sampling of insects and water was done in replicates during September 2014 to 2015. The study recorded 4 orders, 10 families, 12 genera and 12 species of aquatic insects. Highest density of order Hemiptera was found across the sites and seasons. Seasonal variations of environmental variables of water were found moderate. Density of aquatic insects showed significant negative relationship with Electrical conductivity, Total dissolved solid and Rainfall. The study revealed low Shannon Weiner Diversity Index values of aquatic insects (Shanon H՛< 1) in all the sites indicating perturbed condition of the water. Canonical Correspondence Analysis (CCA) showed that the species environment correlations of axis 1 and axis 2 were high and some ...

The sampling of aquatic insects and water was done in replicates during September 2014-2015. The study recorded 4 orders, 8 families, 12 genera and 12 species of aquatic insects. Highest density of order Hemiptera was recorded in pre monsoon and lowest and same density was recorded of order Odonata and Coleoptera in monsoon and winter. Seasonal variations of environmental variables of water were found moderate. Density of aquatic insects showed significant negative relationship with phosphate. The study revealed low Shannon Weiner Diversity Index values of aquatic insects (Shanon H<1) in all the sites indicating perturbed conditions of water. Canonical Correspondence Analysis (CCA) showed that the species environmental correlations of axis 1 and axis 2 were high.
