Abstract: 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 acording to the demand of the termite colony.
