干白蚁（Incisitermes minor）的筑巢生物学尚不清楚。到目前为止，还没有关于I. minor的原位巢廊开发的公开数据。三棵自然感染的锡特卡云杉（Picea sitchensis Bong）。利用x射线计算机断层扫描技术对木材进行了分析，观察了第一个皇家室的结构和白蚁的筑巢行为。一根木头被一群从它们的窝里出来的白蚁侵扰了。另外两根木材被婚飞的未交配的生殖虫侵染。研究表明，干木白蚁从事户外觅食活动，具有很强的觅食灵活性。计算机层析成像还显示，小蚁的筑巢活动具有解剖学上的选择性。最初的皇家房间的结构随着木材的解剖纹理而变化，类似于欧洲梨形或腰果形。
The nesting biology of the drywood termite, Incisitermes minor, is poorly understood. To date, no published data are available regarding the in situ nest-gallery development of I. minor. Three naturally infested Sitka spruce (Picea sitchensis Bong. Carriere) timbers were analyzed by X-ray computer tomography to observe the structure of the first royal chamber and the termite's nest-founding behavior. One timber was infested by a group of termites which emerged from their natal nest. The other two timbers were infested by dealate reproductives from the nuptial flight. The study revealed that the drywood termite engages in outside foraging activity and has great foraging flexibility. Computer tomographic images also revealed that I. minor reproductives showed anatomical selectivity in their nest-founding activity. The structure of the initial royal chambers varied to follow the anatomical texture of the timbers, which resembled either a European pear shape or a cashew nut shape.
