Ehara is a predatory mite that belongs to the family Phytoseiidae. It is mainly found in Jiangxi, Shanghai, Guangdong, and other areas of China. Although is a dominant predatory mite species in China and is also important for agriculture and biological control, not many studies have investigated it. Thus, research on is necessary. However, its application in biological control is hindered by the absence of techniques for the mass rearing of in captivity. We conducted experiments to determine the growth, development, reproduction, and functional response of in this study by indoor single-head rearing at 25 ± 1 °C, 65 ± 5% relative humidity, and a photoperiod of a 16 h:8 h light/dark cycle under laboratory conditions. The results of the age stage, two-sex life table showed that the individuals in the pollen + yeast and pollen + yeast + sucrose groups had significantly higher oviposition period, fecundity, net reproductive rate (R), and gross reproduction rate (GRR) than those in the pollen group. The results of the function response showed that the pollen + yeast + sucrose group was the most favorable for captive breeding of and had the best predatory ability along with rejuvenation and recovery ability. The results of the study provided a theoretical basis for indoor rearing, propagation, and utilization of .
江原钝绥螨是一种属于植绥螨科的捕食性螨类。它主要分布于中国的江西、上海、广东等地区。尽管江原钝绥螨是中国优势捕食性螨类物种，对农业和生物防治也很重要，但对其研究的并不多。因此，有必要对江原钝绥螨进行研究。然而，由于缺乏圈养条件下大量饲养江原钝绥螨的技术，其在生物防治中的应用受到了阻碍。在本研究中，我们在实验室条件下，于25±1℃、相对湿度65±5%、光周期为16小时光照/8小时黑暗循环的条件下，通过室内单头饲养来测定江原钝绥螨的生长、发育、繁殖和功能反应。年龄-阶段两性生命表结果表明，花粉+酵母组和花粉+酵母+蔗糖组个体的产卵期、繁殖力、净生殖率（R）和总生殖率（GRR）显著高于花粉组。功能反应结果表明，花粉+酵母+蔗糖组最有利于江原钝绥螨的圈养繁殖，并且具有最佳的捕食能力以及恢复活力和恢复能力。该研究结果为江原钝绥螨的室内饲养、繁殖和利用提供了理论依据。
