Toba, North Sumatera is famous not only for its tourism destination but also for biodiversity. The aim of this research is to explore the potency of the local plant from Toba as bioinsecticide. Six local plant samples, which consists of genus Compositae, Meliaceae, Staphyleaceae, and Actinidiaceae, were obtained from the Toba region,. The macerated extracts were tested their insecticidal activity against Coptotermes gestroi and Spodoptera litura. Bioassay results showed that leaves extract of Ingul ( Toona sinensis ) at a concentration of 10% (w/v) had the highest mortality effect against Coptotermes gestroi on the tenth day of observation. Whereas, leaves extracts of Pirdot (Saurauia bracteosa), Ingul ( Toona sinensis ), and Haurese ( Azadirachta indica ) at the concentration of 1% (w/v) showed the best insecticidal effect with 80% mortality percentage respectively against Spodoptera litura in 4 hours of observation.
