Seasonal Influence of Agricultural Pesticide Runoff on Aquatic Insect Community Structure in Semi-Arid Freshwater Systems of Telangana, India

Abstract Agricultural intensification in semi-arid regions of South India has significantly increased the application of synthetic pesticides, raising concerns regarding their unintended ecological consequences. Aquatic insects, which form the foundation of freshwater food webs, are particularly vulnerable to agrochemical runoff. The present study evaluated the seasonal impact of agricultural pesticide contamination on non-target aquatic insect biodiversity in selected freshwater bodies of the Karimnagar region, Telangana. Comparative sampling was conducted across pesticide-influenced sites adjacent to paddy and cotton fields and relatively undisturbed control sites. Diversity indices including Shannon–Wiener and Simpson’s index were calculated to assess ecological changes. The results revealed a measurable decline in species richness and abundance in pesticide-exposed habitats, particularly during the post-monsoon agricultural peak season. Sensitive taxa such as Ephemeroptera and Trichoptera showed substantial reductions, whereas tolerant Dipteran species exhibited increased dominance. The findings highlight the need for sustainable pest management strategies to preserve freshwater biodiversity and ecosystem stability.
