Abstract
Aquatic entomofauna spend all or part of their life cycle in the water bodies. From a logical standpoint, aquatic entomofauna make good study specimens because they are taxonomically rich, diversified, abundant and easily surveyed. Abundance and diversity of aquatic entomofauna gives an alarm or an indication of the overall health of the water body. According to aquatic entomologists, aquatic entomofauna respond to the specific changes in the water conditions and they have become indicators of water body. The presence or absence of some aquatic entomofauna indicates the degree of pollution. Physical and chemical analysis are very expensive compare to biological analysis. Concentration of pollutants vary greatly with time and space. So, physical and chemical monitoring cannot detect the non-point source of pollution. But, seasonal sampling of aquatic entomofauna community provides an indication of past condition as well as present condition of the selected water body. Every aquatic entomofauna has different tolerance value in which only few entomofauna can survive in polluted ecosystems. Thus, condition of water body can be evaluated by using aquatic entomofauna. Throughout the world, aquatic entomofauna is widely recommended by aquatic entomologist as the biological indicator of water quality. Using aquatic entomofauna for routine biomonitoring of aquatic body will facilitate better conservation of environment. The goal of this paper is to summarise aspects of biomonitoring, the use of aquatic entomofauna in predicting the state of aquatic systems and the need for research, with a focus on recent developments of aquatic biodiversity Index and biomonitoring scores.
