Revealing the respiratory system of the coffee berry borer (Hypothenemus hampei; Coleoptera: Curculionidae: Scolytinae) using micro-computed tomography
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.This paper benefitted from the sub-award
