Abstract

The present study investigates the toxicological impact of deltamethrin, a widely used synthetic pyrethroid insecticide used in agriculture, specifically targeting the freshwater crab Barytelphusa cunicularis. The research delves into the insecticide’s mechanism of action and acute toxicity on the crab species. With the persistent presence of deltamethrin in soil disrupting microbial activity and water contamination posing threats to aquatic ecosystems. The investigation aimed to determine the lethal toxicity concentration of pesticide. The experiment reveals LC50 values at 24, 48, 72, and 96 hours, indicating concentrations of 0.0125, 0.0075, 0.006 and 0.0049 ppm respectively. The findings demonstrate a correlation between increased pesticide concentration and exposure period with a rise in percentage mortality. Adverse effects observed on B. cunicularis populations underscore the need to comprehend deltamethrins impact on non-target organisms. This research contributes significant insights into deltamethrins toxicology, offering valuable information for decision-making and in promoting sustainable pest management practices.

Keywords: Deltamethrin, toxicity, acute toxicity, LC50 values, environmental footprint
