20-Hydroxyecdysone regulation of H-fibroin gene in the stored grain pest Corcyra cephalonica, during the last instar larval development

▶ H-Fibroin is 20-hydroxyecdysone regulated. ▶ First report of a functional ecdysone response element (EcRE) in the upstream of H-Fibroin. ▶ Ecdysone Receptor binds to EcRE and regulates H-Fibroin expression. ▶ Usage of non-steroidal agonists can provide efficient control of lepidopteran silk producing pests.
