Growth and Partial Metamorphosis of Imaginal Disks of the Greater Wax Moth, Galleria mellonella, in vitro

Abstract

THE most important of the problems of insect metamorphosis is the nature of the action of ecdysone. There is a particular lack of knowledge of the stages between the initiation of metamorphosis by ecdysone and the final differentiation into the adult. Experiments on the action of pure ecdysone in vitro have been conducted with systems which respond in a limited way to ecdysone but do not grow or metamorphose1,2. This communication reports the initiation of metamorphosis in an insect tissue by pure ecdysone in vitro.
