The coffee berry borer (Hypothenemus hampei) is the most economically important insect pest of coffee globally. Micro-computed tomography (micro-CT) was used to reconstruct the respiratory system of this species for the first time; this is the smallest insect (ca. 2 mm long) for which this has been done to date. Anatomical details of the spiracles and tracheal tubes are described, images presented, and new terms introduced. The total volume and the relationship between tracheal lumen diameter, length and volume are also presented. The total length of the tracheal tubes are seventy times the length of the entire animal. Videos and a 3D model for use with mobile devices are included as supplementary information; these could be useful for future research and for teaching insect anatomy to students and the public in general.

咖啡果蛀果象（Hypothenemus hampei）是全球咖啡种植中最重要的经济害虫。本文首次利用微计算机断层扫描（micro-CT）对该物种的呼吸系统进行了重建；这是迄今为止对最小的昆虫（约 2 毫米长）进行的重建。本文描述了气门和气管的解剖细节，展示了图像，并引入了新的术语。还给出了总容积以及气管腔直径、长度和容积之间的关系。气管的总长度是整个动物长度的七十倍。视频和一个用于移动设备的 3D 模型作为补充信息提供；这些对于未来的研究以及向学生和公众教授昆虫解剖学都非常有用。
