The peptides eclosion hormone(EH) and ecdysis\|triggering hormone(ETH) trigger ecdysis behaviors and other physiological changes which occur at the end of the molt.

Now,this paper introduces the actualities of crustacean and insect chitinase research,including the chitinase s properties,structure,molecular biology and its physiological function in the periodic ecdysis of arthropods.

The ecdysis mechanism is very important for the growth of H.
