Abstract

In an attempt to find natural and cheaper methods for the control of stored-product pests of cereals, some traditionally useful Ghanaian plant materials were evaluated. 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.
