中文摘要：
【目的】 了解小头钩白蚁Ancistrotermes dimorphus Tsai et Chen的蚁巢结构、各品级在腔室中的分布和巢群个体数量，为有效防控该种白蚁提供科学依据。【方法】 采用蚁巢定位和巢体结构解剖法研究蚁巢结构；采用统计法确定各品级在腔室中的分布和巢群个体数量。【结果】 小头钩白蚁巢由腔室、菌圃、蚁路、王室、候飞室和分飞孔六部分组成；巢群个体数量为12 255~24 230头（含卵粒）；卵、幼蚁、若蚁、工蚁、兵蚁和有翅成虫分散分布在蚁巢腔室中，并不集中于某一特定区域。【结论】 小头钩白蚁巢属于极端分散类型，巢群个体数量较少。
英文摘要：
[Objectives] To investigate the nest structure, distribution of castes, and the total number of individuals, in nests of Ancistrotermes dimorphus Tsai et Chen. [Methods] Nests were located and dissected to reveal their structure. Statistical methods were used to determine the distribution of castes within nests and the total number of individuals in each nest. [Results] Nests of A. dimorphus consist of a fungus garden, a termitarium galley, a queen’s chamber, a swarming exit room and a swarming exit hole. The total number of individual termites (including eggs) in each nest ranged from 12 255-24 230. Eggs, larvae, nymphs, workers, soldiers and winged adults were scattered throughout the nest chamber rather than segregated in particular areas. [Conclusion] Nests of A. dimorphus are of the extreme dispersed type and contain fewer individuals than those of other termite species.
