ANSWER: ECDYSONE
EXPLANATION: Ecdysone is produced and released from the prothoracic gland located at the prothorax of the insects, which act mainly to stimulates molting or ecdysis (i.e ex-sheating of old cuticle) in insects.
Moreover, the release of ecdysone to trigger molting and metamorphosis, is stimulated by PTTH .
Furthermore, in cases where juvenile hormone is absent, an insect will still metamorphose into the adult form.
