Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers

..., desert beetles. While we have shown that insects monitor oxygen precisely, we do not know how that happens or which tissues and cells are involved. Once we're equipped with a better knowledge of the insect breathing pattern it could shed light on when pesticides should be used to control insects -- crucial...
