Abstract
Mosquitoes are responsible for transmitting various human diseases and contribute to millions of deaths each year. This study examines the effectiveness of leaf extracts from Barleria longiflora on larvae of the filarial vector, Culex quinquefasciatus. The preparation of extracts were using petroleum ether, ethyl acetate, and ethanol. Larvicidal activity assays were conducted on the B. longiflora extracts at different concentrations of 0.625%, 1.25%, 2.5%, and 5%. The larval mortality in percentage was assessed after 48 and 72 hours. The ethyl acetate extract of B. longiflora revealed the highest efficacy on Cx. quinquefasciatus larvae at the 5% concentration, with a lethal concentration (LC50) value of 6.439. The crude extracts of B. longiflora displayed significant potential for vector control. These extracts may contain active phytochemicals that require further investigation. Additionally, plant-derived compounds offer a positive, eco-friendly method for mosquito vector control programs.
