Defining the Anti-Metamorphic Action of Juvenile Hormone

Part of the Proceedings in Life Sciences book series (LIFE SCIENCES)


The morphological changes which accompany insect metamorphosis are frequently dramatic. Yet metamorphosis is controlled by the interaction of but two hormones. An ecdysteroid initiates all molts and promotes metamorphosis unless a juvenoid is also present. In the presence of both juvenoids and ecdysteroids insects molt without changing metamorphic stage.
