Summary It is shown that both follicle cell sheath and ooplasm contain only small quantities ofHelix-hydrolyzable ecdysteroid conjugates and that 20-hydroxy-ecdysone is the predominant free ecdysteroid. Its concentration is very high in the follicle cell sheath immediately before chorion formation (6825 ng/g) and much lower after chorion formation (150 ng/g), while it is 234 ng/g and 95 ng/g in the ooplasm at the same stages respectively.
