Abstract

Mosquito-borne diseases are a significant global health challenge, with a substantial burden in regions like India, where environmental factors and urbanization exacerbate the risk of such diseases. Among the myriad mosquito species, Aedes aegypti is a prominent vector responsible for transmitting dengue fever, a disease with serious health implications. Conventional mosquito control strategies, including chemical insecticides, are fraught with issues such as resistance development, environmental impact, and high costs. As a response, there is a growing interest in exploring plant-based alternatives for mosquito management.

This study focuses on the larvicidal potential of Stachys byzantina, a plant from the Lamiaceae family known for its medicinal properties. The study assessed the effectiveness of methanol, ethanol, chloroform, acetone, and hexane extracts of S. byzantina at multiple concentrations. The results revealed that the methanol extract exhibited the highest larvicidal activity, achieving a mortality rate of 85.71% at the highest concentration (400 ppm) and demonstrating the lowest LC50 (124.63 ppm) and LC90 (408.52 ppm) values among the solvents tested. Ethanol also showed considerable efficacy, though slightly less than methanol. Chloroform and acetone extracts displayed moderate activity, while hexane was the least effective. These findings suggest that S. byzantina possesses potent bioactive compounds with significant larvicidal properties, highlighting its potential as an effective and sustainable alternative to synthetic insecticides.
