The developmental stages of the acarid mite, Tyrophagus tropics Robertson (family Acaridae) included egg, larvae, protonymph, tritonymph and adult stage. Mites reared at different food types under 26±2°C., and 75±5% RH. The growth and development from egg to adult involved incubation, larval, protonymphal, deutonymphal and tritonymphal stages were 7.28 ± 0.24, 7.39 ± 0.31, 8.92±0.21 and 8.83 ± 0.27 days for female while it was 6.86 ± 0.18, 6.81± 0.18, 8.57 ± 0.25 and 8.29 ± 0.13 days for male when fed on yeast, luncheon, Hard cheese and peanuts, respectively. The preoviposition period was 2.06±0.13, 3.78 ± 0.26, 3.22 ± 0.59 and 3.06 ± 0.13 days, respectively. Generation time was averaged 9.33 ± 0.20, 11.17 ± 0.39, 12.14 ± 0.58 and 11.89 ±0.26 days respectively, at the previous pattern. Oviposition period averaged 7.00 ± 266, 9.83 ± 2.41, 7.25±1.82 and 7.33 ±1.78 days respectively. The post-oviposition period averaged 2.00±1.13, 2.42±1.51, 2.17±1.34 and 2.25 ± 1.66 days, when all the individual reread on yeast, luncheon, hard cheese and peanuts, respectively
