dc.description.abstract | In termites, the maturation of the female reproductive system is progressive following post-embryonic development. In Silvestritermes euamignathus, the imaginal line is characterized by five nymphal instars that develop into the imago, but it can deviate in some instars to neotenic reproductives. In order to understand the rate of development of the female reproductive system throughout post-embryonic development, we analyzed the morphology of the reproductive system of nymphs, characterizing the stage of development and comparing it with neotenics and primary queens. We also followed embryonic development and compared eggs from neotenics and primary queens from incipient and mature colonies. Our results showed that gonadal development follows the post-embryonic instars, and previtellogenic oocytes are present in third-instar nymphs and are retained for the next two successive nymphal instars. The full maturation of the ovaries with vitellogenic oocytes requires molting to either imagos or neotenics. Eggs from neotenics follow the same embryonic development and each stage presents similar volume when compared to those of mature primary queens. Eggs of primary queens from incipient colonies are greater in volume than those of mature primary queens and of neotenics, suggesting an investment in egg quality rather than quantity during colony foundation. | en |
