Amblyseius womersleyi (Schicha) was reared in a closed system in a vial ( 5.6 cm × 3.7 cm diam.) at 26 ± 1℃, 13L:11D and 50%, 60%, 70%, 80% and 90% RH. The highest egg hatching rate (100%) of A. womersleyi was found at 80% RH, which was not significantly different from those tested at 70%, and 90% RH, but was higher than those at 50% and 60%. The optimal relative humidity to preserve the predaceous mites in a vial without prey and water was 90% RH. The days of 50% mortality reached for larvae, protonymphs, adult males and adult females were 2.6, 2.6, 4.4 and 3.7 days, respectively. With sufficient food supply, a high percentage of eggs, larvae, protonymphs and deutonymphs developed were found at 70 - 90 % RH. Relative humidity significantly influences the daily prey consumption rate of adult females of A. womersleyi, but not the daily fecundity. The maximal number of predators (1296 ± 161.7 mites/vial) were reared and reached at day 21, under a closed propagation conditions with daily food supply of 0.01g and 0.02g of eggs and larvae of Tetranychus urticae for 1-14 days and 15-21 days, respectively. The predator densities reached highest ( 1296±161.7 mites/vial ) at day 21. The advantages and superiorities of using closed rearing unit of a vial rather than open artificial stages were compared and discussed.
