摘要

As a social insect, termites have different castes and division of labor in a colony. Investigating the social behavior of subterranean termites is a challenge due to the cryptic nature and large colony size. Planar arenas are commonly used to study these termites under laboratory conditions, and have provided several advantages. However, there is no means to designate areas such as a royal chamber or central nest from foraging sites because reproductives can move freely across arenas. In this study, we examined the minimum passing size of different castes of Coptotermes formosanus Shiraki (Blattodea: Rhinotermitidae), in order to develop a reproductive excluder and correlated minimum passing size with head widths and heights. We found that workers and soldiers of C. formosanus were able to pass through a gap greater than or equal to 0.7 mm. Our results showed that there are significant differences in the head width and height based on castes and head height was more critical than head width to determine passing size. We further confirmed feasibilities of the reproductive excluders using incipient colonies of C. formosanus. Confining reproductives using the excluder in laboratory experiments will provide more chances to study the royal chamber and central nest independently of foraging sites.

Formosanus的工人和士兵能够通过大于或等于0.7毫米的间隙。我们的研究结果表明，基于铸件的头部宽度和高度存在显着差异，头部高度比头部宽度更为关键，以确定通过尺寸。我们进一步确认了使用C. FormoSanus的初始菌落的生殖排斥者的可行性。利用除了实验室实验中使用排除者的生殖器将提供更多机会，以独立于觅食地点研究皇家室和中央巢。
