摘 要：
昆虫蜕皮是由数种激素分级调控的一个重要生长发育过程。在蜕皮之前,脑神经分泌细胞合成和分泌促前胸腺素(prothoracicotropic hormone,PTTH)并促进前胸腺中蜕皮激素(ecdysone,Ecd)的产生。随后,Ecd促进气门腺Inka细胞合成蜕壳启动激素(ecdysis-triggering hormone,ETH),同时抑制ETH的分泌,对ETH具有双重调控作用。血淋巴中Ecd滴度下降后,羽化激素(eclosion hormone,EH)促进ETH的分泌。最终,ETH启动昆虫的蜕皮。

摘 要：
Insect molting is an important process of growth and development controlled by a cascade of insect hormones. Prior to molting, brain neurosecretory cells synthesize and secrete prothoracicotropic hormone (PTTH) to stimulate the production of ecdysone (Ecd) by the prothoracic gland. Thereafter, Ecd promotes Inka cells to synthesize ecdysis-triggering hormone (ETH) but inhibits its secretion. Once the hemolymph Ecd titer decreases, eclosion hormone (EH) stimulates the secretion of ETH. Finally, ETH triggers the insect to molt.
