Pheromone content in the pheromone gland of the female moth, Bombyx mori, declines after mating with a time course closely resembling that of decapitated females. The inactivation of pheromone production after mating was prevented when the ventral nerve code or a pair of peripheral nerves (N4) extending from the terminal abdominal ganglion was severed before mating. In contrast, the post-mating inactivation of pheromone production was not prevented when the ventral nerve cord was transected 1 hr after the initiation of mating. Although females produced only a small amount of pheromone when the connection between the brain and the suboesophageal ganglion (SG) was cut at an early pupal stage, mating did not induce a significant decline of pheromone production in these females. The results suggest that inactivation of pheromone production is mediated by a neural signal, originating from a peripheral receptor, that is sent via the ventral nerve cord to the brain-SG complex to suppress activity of the neurosecretory cells responsible for the release of pheromonotropic neuropeptides, such as a pheromone biosynthesis activating neuropeptide (PBAN).
