is a predatory mite species that could potentially be used for the biological control of spider mites and thrips. Floral resources can provide excellent habitats and abundant nutrients for natural enemies. The objective of this experiment was to evaluate the effects of eight floral resources on the longevity, fecundity, and predation ability of . Among the considered plants, led to the highest longevity (24 days) and fecundity (13.8 eggs) of , while resulted in the lowest longevity (7 days) and fecundity (0.1 eggs) observed in the predatory mites. By comparing the effects of three nectar and pollen plants on the predation of predatory mites, it was observed that still exhibited a type II functional response to . In the presence of pollen, the predation efficacy (/) of exhibited a lower value, compared to that in the absence of pollen (Control: / = 24.00). When pollen was supplied, the maximum consumption (1/) of predatory mites was higher than in its absence (Control: 1/ = 9.90 d), with the highest value obtained in the presence of pollen (: 1/ = 17.86 d). The influence coefficient of predation of on in the presence of pollen was compared in the presence of three nectar and pollen plants: , , and . At low prey densities, the influence coefficient of exceeded that of , and the overall influence coefficient values were negative (i.e., the presence of pollen reduced predatory mite feeding on ). They exhibited similar values at high prey densities, and all of the influence coefficient values were close to 0 (i.e., the presence of pollen had no effect on predatory mite feeding on ). The findings revealed that diverse plant species exert differential impacts on , with some influencing its lifespan and others affecting its reproductive capabilities. Furthermore, the presence of nectar and pollen plants had a significant impact on predatory mite feeding on at low prey densities; however, this effect diminished as the prey density increased. Therefore, we recommend planting , , and in the field to ensure an ample population of predatory mites. The obtained results hold significant implications for the utilization of nectar and pollen plants in eco-friendly pest management strategies within agricultural contexts.
是一种捕食性螨类物种，有可能用于对叶螨和蓟马的生物防治。花卉资源可为天敌提供优良的栖息地和丰富的养分。本实验的目的是评估八种花卉资源对[捕食性螨类物种名称]的寿命、繁殖力和捕食能力的影响。在所考虑的植物中，[植物名称1]使[捕食性螨类物种名称]的寿命最长（24天）且繁殖力最高（13.8枚卵），而[植物名称2]导致捕食性螨类观察到的寿命最短（7天）和繁殖力最低（0.1枚卵）。通过比较三种花蜜和花粉植物对捕食性螨类捕食的影响，观察到[捕食性螨类物种名称]对[猎物名称]仍表现出II型功能反应。在有花粉存在的情况下，[捕食性螨类物种名称]的捕食效率（/）与无花粉时相比呈现较低的值（对照：/ = 24.00）。当提供花粉时，捕食性螨类的最大捕食量（1/）高于无花粉时（对照：1/ = 9.90天），在[花粉植物名称]花粉存在时获得最高值（：1/ = 17.86天）。在三种花蜜和花粉植物[植物名称3]、[植物名称4]和[植物名称5]存在的情况下，比较了花粉存在时[捕食性螨类物种名称]对[猎物名称]捕食的影响系数。在低猎物密度下，[捕食性螨类物种名称]的影响系数超过了[另一种捕食性螨类或相关物种名称]，且总体影响系数值为负（即花粉的存在减少了捕食性螨类对[猎物名称]的取食）。在高猎物密度下它们表现出相似的值，且所有影响系数值都接近0（即花粉的存在对捕食性螨类对[猎物名称]的取食没有影响）。研究结果表明，不同的植物物种对[捕食性螨类物种名称]有不同的影响，一些影响其寿命，另一些影响其繁殖能力。此外，花蜜和花粉植物的存在在低猎物密度下对捕食性螨类取食[猎物名称]有显著影响；然而，随着猎物密度增加这种影响减弱。因此，我们建议在田间种植[植物名称3]、[植物名称4]和[植物名称5]以确保有充足的捕食性螨类种群。所获得的结果对于在农业环境中利用花蜜和花粉植物制定生态友好型害虫管理策略具有重要意义。
