Crude plant products have been widely used by different communities in Africa for pest control. Synthetic insecticides have a number of drawbacks, such as development of genetic resistance, eco-toxicity, negative health effects to users and high cost of application. However, not enough scientific research has been conducted on the efficacy of traditional methods in weevil control, the chemical profiles of plant products and their safety to the users. The bioactivities of the powedered products and essential oils of three plants, namely Ocimum gratissimum, Ocimum americanum and Lantana camara, growing in Eastern Kenya against common bean weevil (Acanthoscelides obtectus) were determined. Actellic Super and untreated bean grains were used as positive and negative control, respectively. The powdered plant materials (dried leaves) induced relatively low mortality, with the most effective.
