Larvicidal Efficacy Of Pergularia Daemia Leaf Extract Against Aedes Aegypti, And Culex Quinquefasciatus.
Main Article Content
Abstract
Mosquitoes pose a significant threat to public health by transmitting various diseases worldwide. In South-East Asian countries like India, the vector-borne diseases have become a pressing issue. Aedes aegypti and Culex quinquefasciatus are prominent mosquito species responsible for spreading viral infections like dengue and West Nile virus. Traditional vector control methods involving synthetic insecticides present environmental and health hazards, prompting the search for eco-friendly alternatives. This study focuses on Pergularia daemia, a plant with known medicinal properties, as a potential source of bioactive compounds for mosquito control. Crude extracts from P. daemia leaves were prepared using different solvents, and phytochemical screening revealed the presence of alkaloids, steroids, tannins, saponins, flavonoids, and phenolic compounds. Ethanol extracts exhibited the highest larvicidal activity against Ae. aegypti and Cx. quinquefasciatus larvae, with mortality rates proportional to concentration. The results suggest that P. daemia extracts, particularly those in ethanol, hold promise as effective and environmentally friendly mosquito larvicides.
