| Abstract: | Diapausing Bombyx mori eggs were treated with 20-hydroxyecdysone as follows: a 30 minute immersion in bleaching water was followed by a 24-hour soaking in a 10?4 M solution of the hormone. Of the treated embryos 85% developed to some extent and 25% of them terminated their embryonic development. The efficiency of the treatment rapidly decreased when eggs were allowed to hibernate at 7°C in order to break diapause. |
