Mass rearing of the predatory mite Neoseiulus californicus (McGregor) (Acari: Phytoseiidae) using natural (prey) methods is costly and laborious, limiting its application in the biological control of pests. A high-production, low-cost method using a prey substitute would help to relieve this problem. Oulenziella bakeri Hughes (Acari: Winterschmidtiidae) could be an alternative prey source, but studies on the reproductive parameters of N. californicus under rearing conditions are lacking. This study evaluated the potential of O. bakeri as an alternative prey in N. californicus rearing by comparing developmental parameters among N. californicus reared on three diets based on an age-stage two-sex life table. We found that the preoviposition period and developmental time of N. californicus did not vary based on diet. The fecundity of N. californicus adults reared on O. bakeri was 29.8 eggs per female, which was lower than that of adults reared on Tetranychus urticae Koch (Acari: Tetranychidae) (42.9 eggs per female); there was no significant difference between O. bakeri and apple pollen (30.2 eggs per female). The oviposition rate of mites fed on O. bakeri was 69% of that fed on T. urticae. Neoseiulus californicus reared on O. bakeri and apple pollen showed the same intrinsic rate of increase (0.25 per day), which was 86% of the rate of those fed on T. urticae. Compared with predatory mites reared on natural prey, N. californicus reared on O. bakeri had a high survival rate and good oviposition and population growth parameters, suggesting that O. bakeri is suitable for the rearing of N. californicus.

使用自然（捕食）方法大规模饲养捕食性螨Neoseiulus californicus (McGregor)（蜱螨：植螨科）成本高昂且费力，限制了其在害虫生物防治中的应用。使用猎物替代品的高产量、低成本方法将有助于缓解这个问题。Oulenziella Bakeri Hughes（螨虫：Winterschmidtiidae）可能是一种替代猎物来源，但缺乏对加州猪笼草在饲养条件下的繁殖参数的研究。本研究通过比较基于年龄阶段两性生命表的三种饮食饲养的加州猪笼草的发育参数，评估了巴氏猪笼草作为加州猪笼草饲养中替代猎物的潜力。我们发现加州猪笼草的产卵前期和发育时间并不因饮食而变化。饲养在O.bakeri上的加州N. californicus成虫的繁殖力为每雌性 29.8 个卵，低于饲养在二斑叶螨 (Acari: Tetranychidae) 上的成虫 (每雌性 42.9 个卵)；O.bakeri和苹果花粉之间没有显着差异（每个雌性 30.2 个卵）。取食巴氏螨的产卵率是取食二斑螨的69% 。以O.bakeri和苹果花粉饲养的加州新狒狒表现出相同的内在增长率（每天 0.25），是用二斑绦虫饲养的加州新狒狒的 86％ 。与以自然猎物饲养的捕食螨相比，以O.bakeri饲养的加州猪笼草具有较高的存活率以及良好的产卵和种群生长参数，表明O.bakeri适合饲养加州猪笼草。
