The repetitions were done three times with four types of solutions which are, control (aquades), and kecombrang extracts 3%, 4.5%, 6%. Every repetitions were perceived at 3 intervals 10 minutes, 20 minutes , 30 minutes. Mortality of Aedes spp seen after 24th hours. From the One Way ANOVA test found significant differences in each flower extract concentration effect kecombrang Based on the result of this research, it is conclude that extract of kecombrang flowers have a potential as an insecticide against Aedes spp and effective in 4.5 % concentrate.Key words: Kecombrang, extract, aedes spp, natural insectiside
