Resumo: Dengue Hemorrhagic Fever (DHF) control still depend on the insecticide fogging and larviciding. Several plants have effective natural toxic contents against mosquito larvae. This study aims to determine larvicidal potential of ethanol extract of duku (Lansium domesticum Corr.) seed against Aedes aegypti. The sample were duku seeds obtained from the village of Lubuk Batang, Ogan Komering Ulu. The seeds were dried and milled into powder then maserated in alcohol 70% with stirring for three days. The extract was evaporated using rotary evaporator and water bath then dissolved with aquadest. Larvicidal assay was using 25 larvae of Ae. aegypti for each concentration in 100 ml solution with 5 replications. Phytochemical assay of extract includes alkaloids, flavonoids and saponins. Larvicidal assay includes five concentrations ranged from 4000, 5000, 6000, 8000, to 10000 ppm and control. Phytochemical assay showed that the ethanol extract of duku seed contained compounds of alkaloids, flavonoids and saponins. Larvicidal assay showed that the ethanol extract of duku seed resulted in 55.2% larval mortality at the highest concentration (10000 ppm) for 24-hour observation. Based on probit test, LC50 for ethanol extract of duku seed was 9367.5 ppm. Ethanol extract of duku seed has low potential as larvicide against Ae. aegypti.
