A dynamic interplay between chitin synthase and the proteins Expansion/Rebuf reveals that chitin polymerisation and translocation are uncoupled in Drosophila.

PLoS Biology, 2023
Chitin is a highly abundant polymer in nature and a principal component of apical extracellular matrices in insects. In addition, chitin has proved to be an excellent biomaterial with multiple applications.

Extraction and characterization of chitin from granary weevil, Sitophilus granaries L. (Coleoptera: Curculionidae) [PDF]

Arthropods, 2022
Insect chitin has been extracted from granary weevil - Sitophilus granarius L, commonly called wheat weevil in laboratory by treating it with 1 M HCl and 1 M NaOH. This was followed by decolorization. The yield of chitin from this species is 20.2%.
