对米氏裂爪螨（Schizotetranychus celarius复合体的一个新的亚社会种）的雄性群体的后宫归属进行了实验研究。本文介绍了一种用于研究叶螨行为的标记方法。巢所有权（男性居住在巢）的影响不大，男性男性战斗的后果。此外，男性的年龄差异从未影响战斗的结果。然而，男性腿I的长度似乎是一个重要因素。研究了影响男性腿部尺寸变化的因素。腿的长度我受到强烈影响的寄主植物质量，但不受男性年龄。
Several factors which may affect harem ownership by males of Schizotetranychus miscanthi Saito (a new subsocial species of the Schizotetranychus celarius complex) were experimentally tested. A marking method was developed and used for studying spider mite behavior. Nest ownership (longer male residence in a nest) had little influence on the consequence of male-male combat. Furthermore, age differences in males never affected the outcome of the combats. Length of male leg I, however, appeared to be an important factor. Factors affecting variation in male leg size were examined. Length of leg I was strongly affected by host plant quality but not by male age.
