This review summarizes the recent research progress on endocrine regulation of insect pheromone production, especially in the lepidopteran insects, including the structure, production, transportation, regulatory mechanism of pheromone biosynthesis activating neuropeptide(PBAN) and the role of juvenile hormone(JH) and ecdysteroids to pheromone biosynthesis in some species.
