Abstract

The tritium-labeled synthetic ecdysone analog Delta(7)-5beta-cholestene-2beta,-3beta,14alpha-triol-6-one terminated diapause when injected into diapausing tobacco hornworm pupae and was converted into tritium-labeled alpha-ecdysone and tritium-labeled 20-hydroxyecdysone. About half of the crystalline alpha-ecdysone and 20-hydroxyecdysone isolated from the tobacco hornworms 7(1/2) to 8(1/2) days after injection was derived from endogenous steroid precursors and half from the transformation of the synthetic ecdysone analog.
