在鼻白蚁 Reticulitermes speratus (Kolbe)（等翅目：鼻白蚁科）中，已知偶尔会发生兼性孤雌生殖，并且雌性与其他雌性合作建立群体。为了阐明这两只雌性的卵巢发育情况，在实验室条件下建立了早期雌性-雌性集落，并在集落建立后 0.5、1.5、2.5、3.5 和 7.5 个月（分别为 I-V 阶段）观察集落发育过程。检查卵巢发育、卵黄蛋白原基因表达和保幼激素（JH）滴度。观察到两只雌性的精确生殖周期，其中产卵率在I和II阶段相对较高，在III和IV阶段下降，然后在V阶段再次增加。JH III滴度和卵黄原基因表达在这些蜂王的整个生殖周期中平行变化。在所检查的所有阶段的雌性-雌性群体中，两只雌性的卵巢成熟和卵黄发生相似，这表明两只雌性在产卵方面不存在冲突。
In the rhinotermitid termite Reticulitermes speratus (Kolbe) (Isoptera: Rhinotermitidae), facultative parthenogenesis is known to occur occasionally and females cooperate with other females to found the colony. To elucidate the ovarian development in these two females, incipient female-female colonies were established under laboratory conditions, and the process of colony development was observed at 0.5, 1.5, 2.5, 3.5, and 7.5 months (stages I–V, respectively) after colony foundation. Ovarian development, vitellogenin gene expression, and juvenile hormone (JH) titers were examined. A precise reproductive cycle in both females was observed, in which the oviposition rate was relatively higher during stages I and II, decreased during stages III and IV, and then increased again at stage V. JH III titer and vitellogenin gene expression changed in parallel throughout the reproductive cycle of these queens. Ovarian maturation and vitellogenesis were similar in both females in a female-female colony at all stages examined, suggesting that no conflicts existed for two females in terms of oviposition.
