Question
Moulting hormone is secreted by
corpora cardiacum
prothoracic gland
corpora allata
neurosecretory hormone
Solution
B.
prothoracic gland
Moulting hormone (ecdysone) is secreted by prothoracic gland. These glands are paired, bilateral sheet of cells in the thorax. In Periplaneta, this endocrine gland is X-shaped. This gland is stimulated by prothoracicotropic hormone. Ecdysone, by causing transformation from larval to pupal stage, initiates post embryonic growth in insects.
