Where are the "pheromones" of the cabbage white butterfly, Pieris rapae (Lepidoptera: Pieridae)?
Insects in the Lepidoptera order use sex pheromones, which are odorants, to attract the opposite sex. For example, it has been reported that ferrulactone is present in the wings of males as a sex pheromone in the cabbage white butterfly (Pieris rapae). However, we wondered whether ferrulactone are really present in males. Using an Imaging Mass Spectrometer, it was found that ferrulactone was more abundant in females than in males. In addition, it was found that ferrulactone was more abundant in the wing crests and was found to be present in the black scales of the wings.
