To clarify the regulatory mechanisms of the division of labor in termites, I paid attention to the developmental changes during the differentiation of the supplementary reproductives (neotenics) of some species. Especially, in Reticulitermes speratus, neotenic differentiation was induced from premature individuals by the isolation from their maternal nests, and imaginal organ developments could be observed during neotenic differentiation. Moreover, vitellogenin gene expression and juvenile hormone titer were shown to be extraordinarily high in neotenics.

为了阐明白蚁劳动分工的调控机制，我注意到一些物种的辅助生殖体（幼态）分化过程中的发育变化。特别是散白蚁（Reticulitermessperatus），幼态分化是通过将未成熟个体与母巢隔离来诱导的，在幼态分化过程中可以观察到成虫器官的发育。此外，卵黄蛋白原基因表达和保幼激素滴度被证明是非常高的幼态。
