Pheromone biosynthesis activating neuropeptide

The pheromone biosynthesis activation neuropeptide (PBAN) is a neurohormone (member of the PBAN/pyrokinin neuropeptide family) that activates the biosynthesis of pheromones in moths. Moth females release PBAN into their hemolymph during the scotophase to stimulate the biosynthesis of the unique pheromone that will attract the conspecific males. PBAN release is drastically reduced after mating, contributing to the loss in female receptivity.
