Abstract
Rates of population growth of Sitophilus zeamais Mots. and Tribolium castaneum (Herbst) on whole and processed forms of pearl millet, and loss in dry weight of the millet were determined. The forms were whole grain; 10% cracked, 90% whole grain; cracked grain; and millet flour. The population of S. zeamais increased rapidly in the whole and 10% cracked grain treatments, causing a mean loss in dry weight of 8.2 and 7.2%, respectively, in 76 days. Few progeny were produced in the cracked treatment, and in millet flour all adult weevils died within 2-3 weeks. The population of T. castaneum increased slowly in the whole and cracked grain treatments, causing only a 1.38% dry matter loss in the whole grain during the 78-day incubation period. The population increased significantly more in the cracked treatment than in the whole and 10% cracked grain, while large numbers were produced in the millet flour
