本文简要回顾了最近关于白蚁种姓决定的调查结果，重点介绍了汤普森的工作。通过对赤蚁（Reticulitermes arenincola）、黄蚁（R. flavipes）和胫骨蚁（R. tibiaUs）发展的新资料，以及汤普森（Thompson）原始的黄蚁（R. flavipes）资料的检验，作者无法证实汤普森（Thompson）的说法，即在孵化时，不育和生殖阶层可分为两个不同的群体。作者在第3体育场首先能够区分它们，并认为第2体育场可能是区分的关键时期。内在和外在因素都可能在种姓的产生中发挥作用。明显的种姓差异延迟出现，直到在Reticulitermes的3d体育场，至少承认了外部因素发挥作用的机会。各种结构的生长和变形最终导致了三个不同的等级，这是经过连续的阶段所遵循的。群居昆虫的雌雄同体和跨种姓现象表明，生理和遗传因素影响着社会形态和行为的差异。
The results of recent investigations concerning caste determination among termites are briefly reviewed with emphasis upon the work of Thompson. From examination of new data upon the development of Reticulitermes arenincola, R. flavipes, and R. tibiaUs, and of Thompson''s original R. flavipes material, the author was unable to substantiate Thompson''s claim that the sterile and reproductive castes are separable in 2 distinct groups at the time of hatching. The author was able to distinguish them first in stadium 3 and suggests that the 2d stadium may be a critical period in differentiation. Both intrinsic and extrinsic factors may play a role in the production of castes. The delay in appearance of demonstrable caste differences until the 3d stadium in Reticulitermes at least admits of an opportunity for extrinsic factors to be effective. Growth and metamorphosis of various structures which ultimately lead to the 3 differentiated castes have been followed through successive stadia. Gynandromorphs and intercastes among social insects give indication of the physiological and genetic factors influencing both morphological and behavior differences among castes.
