巢穴卫生行为是筑巢动物的重要适应。社会性红蜘蛛 Stigmaeopsis micanthi (Saito) 在多年生蒲苇 (Miscanthus sinensis Anderss) 的叶下表面构建编织巢穴，并在巢穴中成群生活。该物种的巢成员仅在巢内的一个地点排便，以保持巢穴卫生，并且通过挥发性化学物质和触觉提示来维持废物管理。柱花属的其他成员也建造编织巢穴，群居并管理粪便废物，但这些物种在巢穴和群体大小、寄主植物和社会行为方面有所不同。我们调查了四种柱头属植物废物管理的细节。并发现排便地点的位置以及每个物种识别该地点的方式存在差异。与芒草一样，长柱头仅在一个部位排便，并使用挥发性化学物质和触觉提示，而高桥柱头和撒哈拉柱头均在两个部位排便，仅使用触觉提示。我们讨论了属内废物管理差异的原因，以及废物管理方式、巢穴和群体规模之间的关系。
Nest sanitation behavior is an important adaptation in nest-building animals. The social spider mite Stigmaeopsis miscanthi (Saito) constructs woven nests on the leaf undersurface of perennial pampas grass (Miscanthus sinensis Anderss) and lives in the nests in large groups. Nest members of this species defecate at only one site inside the nest for nest sanitation, and the waste management is maintained by volatile chemical and tactile cues. Other members of the genus Stigmaeopsis Banks also construct woven nests, live in groups, and manage their fecal wastes, but the species differ in nest and group size, host plant, and social behavior. We investigated the details of waste management in four Stigmaeopsis spp. and found differences in the location of the defecation site and in the way each species recognizes this site. Like S. miscanthi, Stigmaeopsis longus defecates at only one site and uses volatile chemical and tactile cues, whereas Stigmaeopsis takahashii and Stigmaeopsis saharai both defecate at two sites and use only tactile cues. We discuss the reasons for the waste management differences within the genus, and the relationship between the means of waste management, nest and group size.
