Asian citrus psyllid stylet biogenesis
The manufacture of new stylets (stylet biogenesis) is an extremely complex process that has been detailed in the potato psyllid. Transmission electron microscopy indicates that key features of this process are also present in the pharate adult Asian citrus psyllid. Therefore, this animation was crafted to simplify exposition of the potato psyllid's process so that it can be understood quickly and easily. Only a basic understanding of textbook molting events is needed, i.e. apolysis, molting space, secretion of new cuticle, and ecdysis. The animation also shows examples of key features of the potato psyllid's process that are present in ACP, indicating that both are comparable. Please see the publication below for more details.

Asian citrus psyllid alimentary canal
Certain members of the deprecated order Homoptera have a highly modified alimentary canal wherein the esophagus, anterior midgut, posterior midgut and hindgut are collocated and complexed into an apparently paraphyletic structure called the filter chamber that acts as a kidney, removing the high volume of water from the hostplant foodstream and shunting it directly to the anus. This organ, and the mesal length of the midgut, are of very similar construction in the potato psyllid and the Asian citrus psyllid, and both are mobbed by their respective Liberibacter species.
The presentation herein is an animation crafted to allow for broad scientific audiences to understand basic alimentary canal anatomy and functionality of, in particular, the Asian citrus psyllid.
