Abstract

ABSTRACT Phenotypic plasticity is the ability of individual organisms to alter their phenotypes to persist in response to internal states or changing environments. Like many other organisms, the specialist predatory mite, Phytoseiulus persimilis Athias-Henriot (Acari: Phytoseiidae), showed plasticity in developmental time and size at maturity under food stress. In this study, we investigated the influence of food stress with different temporal feeding variations on the developmental time, prey consumption, and size at maturity of P. persimilis. Individuals of P. persimilis were reared under laboratory conditions using enclosed rearing cells. The predators responded to temporal feeding variations but not to prey densities regarding their developmental time and size at maturity, and the response was sex-specific (i.e. significant only in females). Diet restrictions at different life stages of P. persimilis can induce plasticity in their life history traits. Future studies can investigate whether diet restrictions encountered by individuals at different life stages influence their reproduction and lifespan.

食性限制对捕食螨需要量和发育的时间变化

表型可塑性是个体生物改变其表型以应对内部状态或不断变化的环境的能力。与许多其他生物一样，专为捕食性螨的persimilis Phytoseiulus Athias-Henriot(蜱螨亚纲:Phytoseiidae)在食物胁迫下表现出发育时间和成熟尺寸的可塑性。在本研究中，我们研究了不同时间摄食变化的食物胁迫对紫杉发育时间、猎物摄取量和成熟时大小的影响。在实验室条件下，用封闭的饲养细胞饲养persimilis个体。在发育时间和成熟尺寸方面，捕食者对摄食的时间变化有反应，而对猎物密度没有反应，而且这种反应具有性别特异性(即仅在雌性中显著)。不同生活史阶段的饲粮限制可诱导拟南芥生活史性状的可塑性。未来的研究可以调查个体在不同生命阶段遇到的饮食限制是否会影响他们的繁殖和寿命。

期刊介绍： The International Journal of Acarology has a global readership and publishes original research and review papers on a wide variety of acarological subjects including: • mite and tick behavior • biochemistry • biology • control • ecology • evolution • morphology • physiology • systematics • taxonomy (single species descriptions are discouraged unless accompanied by additional new information on ecology, biology, systematics, etc.) All submitted manuscripts are subject to initial appraisal by the Editor. If the English is not of a quality suitable for reviewers, the manuscript will be returned. If found suitable for further consideration, it will be submitted to peer review by independent, anonymous expert referees. All peer review is single blind.
