长裂叶螨是一种亚社会性的蜘蛛螨，以竹叶编织巢为群居生活。雌雄成虫都保护自己的幼仔不受捕食性螨Typhlodromus besthiae的侵害。在天然林条件下，研究了蜘蛛网和雌蜘蛛的参与对后代存活率的影响。去除网和雌性的实验表明，S。幼长肌的死亡率高于对照组。此外，父母的女性所做的网络对后代的生存产生了积极的影响，可能是通过防止捕食者侵入巢。雌性在巢中的参与也对在短时间内提高其后代的存活率产生了影响。我们不能检测到任何功能的网络和女性以外的保护对捕食者至少5天的实验期间。巢网为S.长喙对幼鸟的生存有重要的作用，它可以阻止普通掠食者（通才）的进入，而雌性则可以在防御入侵巢穴的专门掠食者方面发挥作用。
The subsocial spider mite Schizotetranychus longus lives gregariously in woven nests on leaves of Sasa bamboo. Adults of both sexes defend their young against the predatory mite Typhlodromus bambusae. The effects of web and female attendance of this species on offspring survival were evaluated in a natural forest. Experimental removal of web and females revealed that S. longus young suffered greater mortality than in the control. Furthermore, the web made by parent females had a positive effect on offspring survival, possibly through preventing predators from intruding into the nest. Attendance of a female in a nest also had an effect on improving the survival rate of her offspring over a short period. We could not detect any function of the web and female other than protection against predators at least for the 5 day period of the experiment. The nest web of S. longus has an important function in the survival of young by preventing the entry of pedestrian predators (generalist) and females may play a role in defending against specialized predators which can intrude into the nests.
