The paired ovaries of the investigated species are composed of 20-30 ovarioles of a telotrophic-meroistic type. Each ovariole is subdivided into an apical tropharium (=trophic chamber) and a vitellarium that contains a single developing oocyte. This oocyte is surrounded by a mono-layered follicular epithelium that is responsible for synthesis of precursors of egg envelopes. In Orthezia, synthesis and secretion of precursors of egg envelopes (=choriogenesis) and accumulation of reserve substances in the oocyte cytoplasm (=vitellogenesis) start at the same time. The egg capsule is composed of two envelopes: an internal, thick vitelline envelope and an external, very thin chorion. The egg surface is covered with numerous, irregularly arranged waxy filaments of spiral shape. Eggs are devoid of the micropylar, aeropylar and hydropylar openings.
所研究物种的成对卵巢由20 - 30个端滋式-半滋式类型的卵巢小管组成。每个卵巢小管可细分为顶端滋养区（=滋养室）和卵黄生成区，卵黄生成区含有单个发育中的卵母细胞。这个卵母细胞被单层滤泡上皮包围，该上皮负责卵膜前体的合成。在奥氏粉蚧中，卵膜前体的合成与分泌（=卵壳形成）以及卵母细胞细胞质中储备物质的积累（=卵黄生成）同时开始。卵囊由两层膜组成：内层厚的卵黄膜和外层非常薄的卵壳。卵表面覆盖着许多不规则排列的螺旋形蜡丝。卵没有卵孔、气门孔和水孔开口。
