Using micro‑computed tomography to reveal the anatomy of adult Diaphorina citri Kuwayama (Insecta: Hemiptera, Liviidae) and how it pierces and feeds within a citrus leaf
The Asian citrus psyllid (ACP), Diaphorina citri, is a harmful pest of citrus trees that transmits
Candidatus Liberibacter spp. which causes Huanglongbing (HLB) (citrus greening disease); this is
considered to be the most serious bacterial disease of citrus plants. Here we detail an anatomical
study of the external and internal anatomy (excluding the reproductive system) using micro-computed
tomography (micro-CT). This is the frst complete 3D micro-CT reconstruction of the anatomy of a
psylloid insect and includes a 3D reconstruction of an adult feeding on a citrus leaf that can be used
on mobile devices. Detailed rendered images and videos support frst descriptions of coxal and scapus
antennal glands and sexual diferences in the internal anatomy (hindgut rectum, mesothoracic
ganglion and brain). This represents a signifcant advance in our knowledge of ACP anatomy, and of
psyllids in general. Together the images, videos and 3D model constitute a unique anatomical atlas
and are useful tools for future research and as teaching aids.Kansas State University (KSU)University of Granad
