Epicerura pulverulenta (African Moth)is one of the most important defoliator of Terminalia ivorensis A. Chev. leading to a great reduction in their production and yield potentials. The constant use of chemicals to control these phyto-pathogens poses potential threats to human health and the environment. A non–chemical control strategy such as the use of botanicals would be a better alternative. Botanicals are readily available, safe, efficacious and eco-friendly. This study was undertaken to investigate the effect of Eucalyptus camaldulensis Dehn. Hand Xylopia aethiopia (Dun. ) A. Rich leaf extracts on the leaf gall bug disease of Terminalia ivorensis. The fresh leaves of both plants were blended to fine liquid extracts by conventional maceration techniques using distilled water. Prepared concentration (0.5-2.0%) of the extracts were then tested against the development of the leaf gall bug of Terminalia ivorensis . Benomyl(3%) was used as insecticidal drug. It was observed that the extract treatments had no significant effect expect for table 5,6,and the control which showed a significant effect.
