Tracheal system

The tracheal system of insects, made up of air tubes that branch throughout the body, is one variation on the theme of a folded internal respiratory surface. The largest tubes, called tracheae, open to the outside. The finest branches extend to the surface of nearly every cell, where gas is exchanged by diffusion across the moist epithelium that lines the terminal ends of the tracheal system .

When the chitin ring collapse, oxygen cannot reach the tracheal.Body cell cannot get enough oxygen. The insect will respire anaerobically - less energy produced.
