Tribolium castaneum (Hbst.), Cynaeus angustus (Lec.) and Cryptolestes pusillus (Schönh.) were reared in the laboratory in the USA on flours prepared from sorghum grain that had been stored with different levels of moisture and therefore different degrees of invasion by moulds. Flours with fungi of the groups of Aspergillus glaucus and A. candidus were better media for the growth of the beetles than flours that were not derived from mouldy grain. Grain that was additionally invaded by Penicillium citrinum inhibited the growth of T. castaneum, caused 100% mortality in C. pusillus, but supported larval growth in Cynaeus angustus as well as the untreated control. Reproduction in T. castaneum was enhanced on all mould-damaged flours, and in Cryptolestes pusillus the number of progeny per female increased on flours supporting increased larval size
