Grain sorghum and other cereals are very important to ensure food security. However, during storage they are susceptible to insect pests; hence, the necessity to find sustainable strategies for storage pests control. The efficacy of Diatomaceous Earth (DE) was assessed in the management of two major beetle pests of stored sorghum: Sitophilus zeamais, and Tribolium castaneum. Sorghum was treated with four concentrations of DE (1.5, 3, 4.5, and 6g/kg) and four concentrations of Actellic Super®Dust, a chemical insecticide used as a reference (0.25, 0.5, 0.75, and 1g/kg). The mortality was measured for each treatment after 24, 48, 96 hours, and 7 days of exposure. Mortalities have been corrected for those observed in control jars without insecticides. Both species tested were susceptible to Diatomaceous Earth with a higher susceptibility of S. zeamais compared to T. castaneum. The lowest concentration of Diatomaceous Earth, 0.5 g/kg allowed control of all individuals tested within 96 hours, i.e. 4 days for Sitophilus zeamais and 7 days for Tribolium castaneum. Diatomaceous Earth could be an alternative to chemical insecticides for the control of stored sorghum insect pests, more specifically S. zeamais and T. castaneum.
