Mold growth was determined in stored maize that was unifested and infested with Sitophilus zeamais Motschulsky(Coleoptera: Curculionidae) at 13%, 16%, or 19% initial Change to MC containing 0%, 5%, or 10% BCFM by weight. After 90 d storage of the maize in a vacuum bottle filler simulating the condition in a large bulk of storage at 26.6$^{circ}C$ and 60$pm$5% RH, Aspergillus glaucus was the most prevalent mold in all treatments. The level of A. glaucus infection was higher in the infested than in the uninfested maize at 13% MC. A. flavus was common in maize stored at 16% MC, and A. candidus and A. terreus were observed in the maize at 19% MC. At 13% MC the mean ergosterol levels, an indicator of mold growth, wer 3 times higher in the infested maize than in the uninfested maize. At 16% MC the infested maize contained 42.7-50.0$mu extrm{g}$/g of ergosterol, depending on BCFM content, whereas 35.4-37.9$mu extrm{g}$/g ergosterol was contained in the uninfested maize. At 19% MC the final ergosterol levels were nearly three times higher than at 16% MC, but the presence of S. zeamais did not affect the ergosterol level significantly. There was generally a positive relationship between the level of MC during storage and the number of damaged kernel observed after 80 d.
