Aedes aegypti is the primary vector of dengue hemorrhagic fever (DHF), which remains a major public health concern in Indonesia, including Southeast Sulawesi. Continuous use of chemical larvicides poses risks of resistance development and environmental impacts, thereby necessitating safer alternatives for vector control. This study aimed to evaluate the larvicidal efficacy of ethanol extracts from the leaves and flowers of Lantana camara against A. aegypti larvae. The extracts were prepared through maceration using 96% ethanol, followed by bioassay tests on third- and fourth-instar larvae at concentrations ranging from 10–25 µg/mL. Larval mortality was observed at 24-hour intervals. The results revealed that the leaf extract of L. camaraexhibited higher larvicidal activity than the flower extract, with LC₅₀ and LC₉₀ values of 3.26 µg/mL and 8.31 µg/mL, respectively. Larval mortality increased proportionally with both concentration and exposure time. In conclusion, the leaf extract of L. camara demonstrates potential as an effective and environmentally friendly botanical larvicide for dengue vector control.
