昆虫蜕皮行为的生理生化和分子生物学研究进展

Advances of physiology and biochemistry in insect molting behavior

羽化激素与蜕皮触发激素诱发昆虫蜕皮行为及蜕皮末期的其它生理变化。羽化激素在一些特定的脑神经分泌细胞中合成 ,在蜕皮激素的调控下 ,释放到中枢神经系统和血淋巴中。蜕皮触发激素是由Inka细胞分泌的 ,直接作用于中枢神经系统 ,触发前蜕皮和蜕皮行为。越来越多的证据表明羽化激素可能存在于所有的昆虫中 。

The peptides eclosion hormone(EH) and ecdysis\|triggering hormone(ETH) trigger ecdysis behaviors and other physiological changes which occur at the end of the molt.EH is synthesized in a discrete set of cerebral neurosecretory cells, and is released into the central nervous system and into the hemolymph in response to the declining ecdysteroid titers. ETH is released from the Inka cells,a component of the segmentally paired epitracheal glands,and acts directly on the CNS to trigger preecdysis and ecdysis be...
