Effects of Methoprene and 20-Hydroxyecdysone on the Precocious Metamorphosis Induced by 1, 5-Disubstituted Imidazoles

Abstract

Precocious metamorphosis of the silkworm induced by a variety of 1, 5-disubstituted imidazoles was prevented by the dietary administration of 20-hydroxyecdysone, as well as by the topical application of methoprene, a juvenile hormone mimic.
