The reproductive activity of Labidura riparia females involves, after a 5-day maturation stage, a regular alternation of ovarian cycles and egg-care stages averaging 10 days each. Vitellogenesis is characterized by an increase in the size of the corpora allata (CA) where structured SER bodies appear, and by a rise of juvenile hormone (JH III) content in the hemolymph which is followed by an increase in the level of ecdysteroids. During the egg-care periods, the CA are inactive; structured bodies generate autophagic vacuoles, the titer of JHs and later that of ecdysteroids in the hemolymph decreases and remains stationary. Ovariectomy causes hypertrophy and hyperactivity of the CA for about two months. Subsequently, the titer of JH decreases and old females may display parental behaviour; the level of ecdysteroids falls and remains unchanged. After cauterization of the pars intercerebralis (PI) of the protocerebrum, the ovarian activity stops, the ovary shrinks, the JHs rapidly disappear but ecdysteroids remain at the same or even higher levels than those of normal females of the same age. On the basis of these data, we postulate the existence of a center located in the PI, inhibiting the production of ecdysteroids, and of a stimulating center located outside this area. The PI also exhibits an allatotropic function.
溪岸蠼螋雌虫的生殖活动在经历5天的成熟阶段后，卵巢周期和护卵阶段会有规律地交替出现，每个阶段平均持续10天。卵黄发生的特征是咽侧体（CA）体积增大，出现有结构的滑面内质网体，血淋巴中保幼激素（JH III）含量升高，随后蜕皮甾类激素水平增加。在护卵期，咽侧体不活跃；有结构的体产生自噬泡，血淋巴中保幼激素的滴度以及随后蜕皮甾类激素的滴度降低并保持稳定。卵巢切除会导致咽侧体肥大和活跃约两个月。随后，保幼激素滴度下降，老龄雌虫可能表现出亲代行为；蜕皮甾类激素水平下降并保持不变。在原脑的脑间部（PI）烧灼后，卵巢活动停止，卵巢萎缩，保幼激素迅速消失，但蜕皮甾类激素水平与同龄正常雌虫相同甚至更高。基于这些数据，我们推测存在一个位于脑间部的抑制蜕皮甾类激素产生的中心，以及一个位于该区域之外的刺激中心。脑间部还表现出促咽侧体功能。
