Studies on the regulatory mechanisms of imaginal organ developments during a caste differentiation of termites

为了阐明白蚁分工的调控机制，本文对部分物种补充生殖分化过程中的发育变化进行了研究。特别是在网状白蚁（Reticulitermes speratus）中，幼崽分化是通过与母巢分离而诱导的，并且在幼崽分化过程中可以观察到想象器官的发育。此外，卵黄原蛋白基因表达和幼年激素滴度显示在新生儿中非常高。

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.
