【Abstract】 Chitin and protein were the main and the most important parts in cuticles of insects.This paper discussed the effects of diflubenzuron (DFB) on cuticle proteins in the last instar larvae of the oriental armyworm, Mythimna separata (Walker).DFB reduced the contents of chitin and cuticle proteins. At the same time,it also changed the ratioes of various cuticle proteins.Gel electrophoresis studies showed that there was a new protein bandin DFB treated larvaes.Some protein bands appeared and disappeared later in DFB treated larvaes than in normal ones更多还原
