为了阐明异速生长发育的身体部位伴随着士兵分化的白蚁，我们测量了16个身体部位的士兵，presolarium，pseudergates（工人），幼虫和幼虫的湿木白蚁Hodotermopsis japonica。主成分分析（PCA）进行使用这些参数，这表明分化成士兵不同的发展成成年（生殖）的个人。特别是，在士兵的发展过程中，前部身体部分扩大。同样地，在士兵分化过程中，两个下颌骨的顶端部分的伸长被注意到。下颌骨的X线分析显示分化为晚期士兵后士兵下颌骨的硬化。兵蚁分化过程中的这些形态学变化与它们在殖民地中的作用变化有关。通过士兵分化，这种白蚁种姓的形态在功能上变得适合攻击捕食者，而不适合用它们的下颚以木材为食。基于这些数据，我们认为，一定有一些形态发生因素导致种姓特有的形态，如士兵下颌骨。
To clarify the allometric development of body parts accompanying soldier differentiation in termites, we measured 16 body parts of soldiers, presoldiers, pseudergates (workers), nymphs and larvae of the damp-wood termite Hodotermopsis japonica. Principal component analysis (PCA) was performed using these parameters, which revealed that differentiation into soldiers differed distinctly from development into adult (reproductive) individuals. In particular, the anterior body parts enlarged during development of soldiers. Similarly, elongation of the apical portion of both mandibles was noted during soldier differentiation. X-ray analysis of mandibles revealed sclerotization of the soldier mandibles after differentiation into terminal soldiers. These morphological changes during soldier differentiation are associated with changes in their roles within the colony. Through soldier differentiation, the morphology of this caste of termite becomes functionally suited for attacking predators, and unsuitable for feeding on wood using their mandibles. Based on these data, we suggest that there must be some morphogenetic factors leading caste specific morphology such as soldier mandibles.
