 This research paper explores the larvicidal activity and cytotoxicity of three aromatic plants, against 80s albipictus mosquitoes. The results showed that the hexane extracts of O. Americanum and P. crispum were the most effective, with the lowest median lethal concentrations, LC50. Furthermore, the GCMS analysis of these extracts identified several compounds, such as methyl eugenol, which are known to possess larvicidal properties. This suggests that these plants may be used as alternative sources of natural insecticide. This article was authored by Huime Lim, Sukhi Li, Lai Yee Ho, and others.
