Females injected with this homogenate during the photophase produced the same amount of pheromone and same ratio of components as neck-ligated females injected during the peak of pheromone production. Decapitated females and isolated abdomens also produced pheromone when injected with the brain - subesophageal ganglion homogenate during the photophase. These data show that the neurohormone which stimulates pheromone production is not degraded by enzymes during the photophase and that pheromone is not metabolized at a greater rate during periods when the insect is not producing pheromones.
