Development of Callosubruchus maculatus (F.) in cowpea seeds (Vigna unguiculata (L.) Walp) can be prevented by sterilization of the adult forms and destruction of the eggs, larvae and pupae using an ionizing treatment at doses less than 100 Gy, without causing unfavorable nutritional consequences. Storage of these cowpea seeds in polyethylene bags of a thickness greater than 100 μm avoids all recontamination by this weevil. Economically, the irradiation of such a foodstuff would certainly be worthwhile in Senegal on the condition that the ionizing treatment would also be profitable for other foodstuffs harvested locally, so as to attain a satisfactory utilization rate for the industrial plant which would be set up in this country.
