Inert dusts (IDs), as diatomaceous earth (DE) and kaolin powders are among the most appealing alternatives to synthetic chemicals, against stored-product pests. IDs are environmentally friendly and very low toxic to mammalian. In addition, it has been proven that insects are not able to develop resistance to IDs. In this study the insecticidal activity of two IDs (DE and kaolinite) in comparison with insecticide dusts (malathion and agrothion) were evaluated at two different concentration levels 0.4 and 0.8 w/w, with the admixing wheat grain and cowpea seeds against the adults of two stored product pests cowpea beetle C. maculatus and confused flour beetle T. confusum. The results showed that the toxicity of DE, were higher than insecticide dusts and kaolinite against T. confusum, whereas insecticide dusts were more effective than inert dusts on C. maculatus. The present study suggested that DE exhibited a possibility to be an alternative to the synthetic insecticides in the management of stored product pests, especially T. confusum.
