类雄激素受体在尖唇散白蚁繁殖蚁和工蚁卵子发生中的免疫细胞化学表达

为探讨类雄激素受体 (androgen receptor-like，AR-like)在白蚁卵子发生过程中的作用，采用免疫细胞化学方法对尖唇散白蚁Reticulitermes aculabialis雌性繁殖蚁和工蚁卵子发生中的类雄激素受体进行了定位检测。结果发现：繁殖蚁和工蚁卵巢中均有类雄激素受体免疫阳性反应。类雄激素受体在末龄若虫和成虫卵母细胞的分化期和生长期定位于卵母细胞质，而在成虫的卵黄形成期定位于滤泡细胞；在工蚁卵巢中，类雄激素受体定位于分化期和生长期的卵母细胞质，无卵黄形成期。结果提示类雄激素受体在白蚁的卵子发生过程中有重要作用： 工蚁的卵巢发育受抑制，其卵子发生相当于末龄若虫水平，但根据群体的变化又可以发育为补充繁殖蚁，有发育的潜能。

Immunocytochemical localization of androgen receptor-like in the oogenesis of reproductives and workers of Reticulitermes aculabialis (Isoptera:Rhinotermitidae)

In order to understand the role of androgen receptor-like(AR-like)during the oogenesis of termites,method of immunocytochemical localization was employed to investigate the location of AR-like at different stages of female reproductives and workers during the oogenesis of Reticulitermes aculabialis.The results indicated that the AR-like existed in all ovaries of the last instar nymphs,the swarming females and the workers.AR-like was located in the cytoplasm of oocytes at the differentiation stage and the growth stage,but it was located in the follicular cells at the yolk forming stage.In the ovary of the workers,AR-like was distributed in the cytoplasm of oocytes at the differentiation stage and the growth stage.Yolk forming stage did not exist in workers.The results suggest that AR-like plays an important role in oogenesis of termites:as the ovary development of workers is restrained,the oogenesis of workers is similar to the level of last nymph,but the workers could turn into reproductives according to the demand of the termite colony.
