Pollen is offered as alternative or supplementary food for predacious mites; however, it may vary in its nutritional value. Body weight appears a representative parameter to describe food quality. Thus, we assessed the body weight for adults of the generalist mites Amblyseius swirskii, Amblydromalus limonicus, and Neoseiulus cucumeris reared on 22, 12, and 6 pollen species, respectively. In addition, A. swirskii and A. limonicus was reared on codling moth eggs. In all mite species, female body weight was higher than that of males, ranging between 4.33 and 8.18 µg for A. swirskii, 2.56-6.53 µg for A. limonicus, and 4.66-5.92 µg for N. cucumeris. Male body weight ranged between 1.78 and 3.28 µg, 1.37-3.06 µg, and 2.73-3.03 µg, respectively. Nutritional quality of pollen was neither consistent among the mite species nor among sex, revealing superior quality of Quercus macranthera pollen for females of A. swirskii and Tulipa gesneriana pollen for males, Alnus incana pollen for females of A. limonicus and Aesculus hippocastanum pollen for males, and Ae. hippocastanum pollen for both sexes of N. cucumeris. The results are discussed against the background of known or putative pollen chemistry and mite's nutritional physiology.
花粉被用作捕食螨的替代食物或补充食物；然而，其营养价值可能会有所不同。体重似乎是描述食物质量的一个代表性参数。因此，我们分别评估了以22种、12种和6种花粉饲养的多食性螨斯氏钝绥螨、柠檬钝绥螨和黄瓜新小绥螨成虫的体重。此外，斯氏钝绥螨和柠檬钝绥螨还用苹果蠹蛾卵饲养。在所有螨类中，雌螨体重均高于雄螨，斯氏钝绥螨雌螨体重在4.33至8.18微克之间，柠檬钝绥螨雌螨体重在2.56至6.53微克之间，黄瓜新小绥螨雌螨体重在4.66至5.92微克之间。雄螨体重分别在1.78至3.28微克、1.37至3.06微克和2.73至3.03微克之间。花粉的营养质量在螨类物种之间以及性别之间都不一致，显示出大果栎花粉对斯氏钝绥螨雌螨质量上乘，郁金香花粉对斯氏钝绥螨雄螨质量上乘，灰桤木花粉对柠檬钝绥螨雌螨质量上乘，七叶树花粉对柠檬钝绥螨雄螨质量上乘，七叶树花粉对黄瓜新小绥螨雌雄螨质量都上乘。我们结合已知的或假定的花粉化学和螨类营养生理学背景对结果进行了讨论。
