The maturation of corpora allata (CA) and the competence of pheromone glands in the adult moth Helicoverpa armigera, are both age-related and appear to be correlated. Sex pheromone glands of pharate adults do not produce sex pheromone independently, nor do they respond to exogenous PBAN. Newly emerged moths produce significantly less pheromone than day one moths. JH (juvenile hormone) II was found to be the main JH form produced by CA in vitro. JH II primed pheromone glands of pharate adults to respond to PBAN. In addition, injection or topical application of JH II to newly-emerged females induced pheromone production in the presence of PBAN. Our findings suggest that JH is involved in the initiation of pheromone production of Helicoverpa armigera.
