Schum. Zingiber officinale Rosc., Morinda lucida (L.) (Rubiaceae), Moringa oleifera Lam. (Moringaceae) (seed and leaf) and Garcinia kola Heckel (Guttiferae) on the management of African wood termite under ambient temperature and relative humidity (300c and 72%). Twenty termites were introduced into a covered container and treated with three levels (0.0 g, 0.5 g, 1.0 g) of the various plant extracts. The experiment was laid out in a completely randomised design (CRD) and replicated four times with factorial arrangement of treatments. Mortality was recorded at 12, 24, 36, 48, 60, 72, 84 and 96 hours exposure periods respectively. A. melegueta and G. kola were effective at 60 hours of exposure for 0.5g rate of application recoding 95% mortality while Z. officinale, M. oleifera recorded 100% mortality after 84 hours of exposure. At 1.0 g rate of application, M. oleifera seed and A. melegueta were efficacious after 12 hours, however, M. oleifera recorded 95% mortality after 60 hours and 100 % at 72 hours while A. melegueta and M. lucida recorded 95 and 75 % mortality at 48 hours of exposures respectively. No mortality was recorded untreated experiment. Conclusively, A. melegueta, M. lucida and M. oleifera seed and leaf can be used in the control of wood termite due to higher mortality recorded on application and as a substitute for synthetic insecticides. Key words: Control, Exposure periods, Insecticidal plants, Mortality, Termite.
