Efficacy of Cow Bone Charcoal Dust in the Management ofthe Maize Weevil, Sitophilus zeamais Motsch. [Coleoptera: Curculionidae], and the Lesser Grain Borer, Rhyzopertha dominica Fab. [Coleoptera: Bostrichidae)), Infesting Stored Maize (Zea mays L.)Grains.
Dry bones (femur and ribs) of the African humped cow, Bos indicus (L.), were burnt with wood fire and the resulting charcoal was manually ground and sieved to produce the fine inert cow bone charcoal dust (CBCD) that was admixed-with maize (Zea mays L.) grains at the rates of 0.1 ,0.25,0.5, 1.0,2.0,4.0, and 8.0 g /100 g of grain. Adults of Sitophilus zeamais Motsch. and Rhyzopertha dominica Fab. were exposed to the treated grain and mortality was recorded at 2, 4, 6, and 8 days post-infestation. The study was conducted under ambient conditions (28.5-32.5°C and 50-62 % RH) in the laboratory.
