In this study, two-sex life tableparameters of Ephestia kuehniella (Zeller) were studied on seven cultivars of barley (Dasht, Khorram, Sahra, Reihan03, Fajr30, 5shoor and EH-83-7) and two cultivars of wheat (Bam and Sepahan) at 25 ± 1 °C, 65 ± 5% R.H., and 16:8 (L: D) h. The shortest and the longest larval periods were recorded on Reihan03 (42.58 ± 0.69 days) and EH-83-7 (53.42 ± 0.95 days) cultivars respectively. The longest and the shortest developmental periods for E. kuehniella were found on EH-83-7 (72.12 ± 1.61 days) and on Sepahan (58.19 ± 1.00 days) cultivars respectively. The heaviest and lightest pupaewere observed on Sepahan (21.07 ± 0.77 mg) and Fajr30 (15.20 ± 0.58 mg) cultivars respectively. The intrinsic rate of increase and net reproductive rate were the highest (0.07 ± 0.00 day-1 and 87.41 ± 1.89 offspring, respectively) on Sepahan, and the lowest (0.037 ± 0.00 day-1 and 12.29 ± 0.48 offspring, respectively) on Dasht cultivars. The results indicate that Sepahan wheat cultivar is the most suitable cultivar for the laboratory rearing of E. kuehniella.
