Abstract
Aquatic insects playa pivotal role in freshwater ecosystems. The present study will assess the data on diversity, distribution and the physicochemical parameters across different seasons of aquatic insects in Ambazari, Zilpi and Gorewada Lake under Nagpur District. The Lentic ecosystems are increasingly threatened by anthropogenic activities, including pollution, habitat destruction, and climate change and socioeconomic development ultimately pollutant discharge increases from industry, agriculture and domesticity. Biomonitoring which utilizes biological indicators to assess ecosystem health, has gained prominence as an effective method for evaluating aquatic environments. Traditional water quality assessment methods, such as chemical and physical analysis, provide only an exposure to conditions and may not reflect long-term ecosystem changes. Because of their sensitivity to environmental changes, diverse ecological roles, aquatic insects are particularly valuable bioindicators. In contrast, biomonitoring using aquatic insects offers a more comprehensive approach to assessing ecosystem health by integrating biological responses over time. This review study will explore the role of aquatic insects in biomonitoring lentic ecosystems, the methodologies employed, and the challenges associated with their use. The study highlights various indices, including Pearson’s correlation, Biotic Indices (BMWP and ASPT), Water Quality Index and Comprehensive Pollution Index (CPI) which utilize insect diversity and abundance to infer water quality.
Keywords: Aquatic insects, Biomonitoring, Bioindicators, Pearson’s correlation, Water quality assessment, EPT index.
