Hexane+isopropyl alcohol extract of leaves of Ocimum viride proved most effective in the control of Tribolium castaneum (Coleoptera: Tenebrionidae) and Sitophilus oryzae (Coleoptera: Curculionidae), followed by that of Chromolaena odorata. O. viride showed strong repellent activity and thus deterred the insects from feeding. It reduced survival of both insect pests to less than 25% after 10 days of treatment at concentrations of 0.1 mg ml-1 and above. The results show the potential of O. viride and C. odorata in the control of stored-product insects. © 2000 Elsevier Science Ltd.enCerealsControlGhanaian plantsStored-product insectsArticle
