Oogenesis has been followed with the electron microscope in 2 strains of the malaria mosquito Anopheles gambiae, from the emergence of the adult (oocytes at leptonema) till shortly before the oocytes are ready for oviposition. After pachynema the chromosomes form a karyosphere and a fibrous capsule develops around it. Work on other mosquitoes suggests that the capsule may be related to the synaptonemal complexes. Bot Anopheles strains contain at some time an extrachromosomal (not DNA-containing) body comparable to the karyosphere in size. Clusters of granules are present at the surface of the nucleolus and free in the nucleoplasm. Tentative results indicate that they may contain DNA. During oogenesis the nucleolus becomes very large, mainly because of proliferation of the nucleolonema. Towards the end of oocyte development of the nucleus assumes the large canoe-shape also seen in Aedes and Culex. Nucleolonema traverse the entire nucleus, and modified granular clusters are found throughout.
在冈比亚按蚊的两个品系中，利用电子显微镜对卵子发生过程进行了跟踪研究，研究从成虫羽化（细线期的卵母细胞）开始，直至卵母细胞即将准备好产卵前不久。粗线期后，染色体形成核球，其周围会发育出一层纤维状包膜。对其他蚊子的研究表明，该包膜可能与联会复合体有关。两个按蚊品系在某些时候都含有一个与核球大小相当的染色体外（不含DNA）物体。核仁表面存在颗粒簇，并且在核质中也有游离的颗粒簇。初步结果表明，它们可能含有DNA。在卵子发生过程中，核仁变得非常大，主要是因为核仁线的增殖。在卵母细胞发育接近尾声时，细胞核呈现出在伊蚊和库蚊中也能看到的大独木舟形状。核仁线贯穿整个细胞核，并且在整个细胞核中都能发现经过修饰的颗粒簇。
