During pupal-adult development of the silkworm, Bombyx mori, the ecdysone titer changes, exhibiting two maxima in the females: one on the second day of pupal development and the other just before adult emergence. During the second maximum, ecdysone accumulates in the ovaries. It also accumulates in isolated abdomens, which were prepared just after pupal ecdysis and induced to initiate adult development by injection with β-ecdysone. Several lines of evidence suggest that ecdysone is synthesized in the ovary itself.
在家蚕蛹-成虫发育过程中，蜕皮激素滴度会发生变化，在雌蚕中呈现两个峰值：一个在蛹发育的第二天，另一个在成虫羽化前。在第二个峰值期间，蜕皮激素在卵巢中积累。它也会在刚化蛹后制备的离体腹部中积累，通过注射β-蜕皮激素诱导其开始成虫发育。多条证据表明蜕皮激素是在卵巢自身中合成的。
