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.

新热带白蚁雌性生殖系统的胚胎后发育(等翅目:白蚁科:白蚁科)
在白蚁中,雌性生殖系统的成熟是随着胚胎后发育而逐步进行的。在银蕨中,想象线的特征是发育成想象线的5个若虫,但它可以在一些若虫中偏离到新生生殖。为了了解雌性生殖系统在胚胎后发育过程中的发育速度,我们分析了若虫生殖系统的形态,表征了发育阶段,并将其与新生儿和初级蜂王进行了比较。我们还跟踪了胚胎发育,并比较了来自早期和成熟群体的新生蜂王和初级蜂王的卵。我们的研究结果表明,性腺发育遵循胚胎后期,卵黄前卵母细胞存在于第三期若虫中,并在接下来的两个若虫中保留。卵黄细胞卵巢的完全成熟需要蜕皮成象或新生。新生蜂王的卵遵循相同的胚胎发育,与成熟的初级蜂王相比,每个阶段的卵的体积相似。早期蜂群的初级蜂王的卵体积大于成熟的初级蜂王和新生蜂王的卵,这表明在蜂群建立期间投资于卵的质量而不是数量。

期刊介绍: Arthropod Structure & Development is a Journal of Arthropod Structural Biology, Development, and Functional Morphology; it considers manuscripts that deal with micro- and neuroanatomy, development, biomechanics, organogenesis in particular under comparative and evolutionary aspects but not merely taxonomic papers. The aim of the journal is to publish papers in the areas of functional and comparative anatomy and development, with an emphasis on the role of cellular organization in organ function. The journal will also publish papers on organogenisis, embryonic and postembryonic development, and organ or tissue regeneration and repair. Manuscripts dealing with comparative and evolutionary aspects of microanatomy and development are encouraged.
