Abstract

Five insecticides were tested for the control of stored-grain pests (Sitophilus oryzae (L.), Tribolium castaneum (Hbst.), T. confusum Duv., Cryptolestes pusillus (Schonh.), Oryzaephilus surinamensis (L.) and Rhyzopertha dominica (F.)) in high-moisture sorghum in small bins. The addition of 0.2% propionic acid to prevent spoilage did not influence insect infestations. The best results were obtained with pirimiphos-methyl in sprays at 8.4 p.p.m., followed, in order of decreasing effectiveness, by chlorpyrifos-methyl at 6.7, fenitrothion at 8.9, malathion at 16.7 p.p.m. and a dust formulation of malathion at 11.2 p.p.m
