Toxicological Study of Insecticide Residues and Their Effects on Insect Diversity in Hapur

Abstract

The extensive use of insecticides in modern agriculture has significantly contributed to increased crop productivity and effective pest management; however, the persistence of insecticide residues in the environment poses serious ecological and toxicological concerns. Insecticide contamination adversely affects non-target organisms, particularly beneficial insect populations that play essential roles in pollination, decomposition, nutrient cycling, and biological pest control. The present study investigates the toxicological effects of insecticide residues on insect diversity in Hapur using a comprehensive analytical and review-based approach. The study focuses on commonly used insecticides in agricultural fields, their persistence in soil and water, bioaccumulation potential, and their impacts on insect abundance and species composition. Data were collected from scientific literature, environmental monitoring reports, agricultural surveys, and toxicological studies. The findings indicate that excessive and repeated application of organophosphates, carbamates, pyrethroids, and neonicotinoids has led to significant reductions in beneficial insect populations, including pollinators and predatory insects. Insecticide residues were also found to alter ecological interactions, reduce biodiversity indices, and increase the dominance of resistant pest species. The study emphasizes the urgent need for sustainable pest management strategies, ecological monitoring, and regulated pesticide application to minimize environmental toxicity and conserve insect diversity in agricultural ecosystems.
