Plants are known to have various chemical compounds that have potential to be developed as insecticides. One of the potential plants to be developed as a source of insecticides is Barringtonia asiatica (Lecythidaceae). This research was conducted to determine toxicity of methanolic seed extract of Barringtonia asiatica to mortality and biological character of Spodoptera litura. The evaluation of toxicity was carried out using feeding method. Result of this research indicated that methanolic seed extract of B. asiatica had insecticidal activity with LC50 at concentration of 0.30% and LC90 at concentration of 0.80% in 13 days after treatment with LT50 at 4.8 days. In addition, methanolic seed extract of B. asiatica caused decrease of larval weight, tend to increase duration time of development, reduced leaf consumption and decrease of egg amount oviposited by female of S. litura.
