Activity of ODH is high during larval development on pars intercerebralis which is releasing its allatotropic neurosecretion towards 4 th day of 5 th instar under photophase 16 h. ADH is inhibited during the same period and then activated at the time of spinning when the level of JH I and II is falling; by oxidization of JH I and JH II, possibly JH III is produced.
在16小时光照周期下,五龄幼虫发育期间,咽侧体在第5龄第4天向脑间部释放促咽侧体神经分泌时,咽侧体活性较高。同期,抗利尿激素受到抑制,而在吐丝时,当保幼激素I和II水平下降时,抗利尿激素被激活;通过保幼激素I和保幼激素II的氧化作用,可能产生了保幼激素III。
