Since insects belonging to the Acrididae family have different nutritional preferences, and their physical characteristics differ, they pose a problem in classification for taxonomists. In order to remove this confusion, the biology of the species belonging to this family should be well known. Therefore, the morphology and histology of the female reproductive system of Pseudochorthippus parallelus parallelus (Zetterstedt, 1821) (Orthoptera, Acrididae) and histochemical content of the yolk granules accumulating in oocyte cytoplasm have been studied by using light microscopy and scanning electron microscopy in this paper. The reproductive system of females of this species has five or six ovarioles in each ovary. The histological data revealed that the ovary of P. parallelus parallelus is of panoistic type, with each ovariole divided into a terminal filament, a germarium, a vitellarium, and a pedicel. The histochemical features of the yolk granules which accumulate in the oocyte cytoplasm have been also identified. During the oocyte developmental stage, the accumulation of progressively larger yolk granules has been observed in the ooplasm. Histochemical staining has revealed that these yolk granules are in protein and carbohydrate structures.

Pseudochorthippus parallelus parallelus (Zetterstedt, 1821) (Orthoptera, Acrididae) 雌性生殖系统的形态和组织学以及蛋黄颗粒的组织化学特征

由于属于蝗科的昆虫具有不同的营养偏好，并且它们的物理特征也不同，因此它们给分类学家带来了分类问题。为了消除这种混淆，应该了解属于该科的物种的生物学特性。因此，本文通过光学显微镜和扫描电子显微镜研究了平行拟梭菌（Zetterstedt，1821）（直翅目，蝗科）雌性生殖系统的形态和组织学以及卵母细胞细胞质中积累的卵黄颗粒的组织化学含量。 . 该物种雌性的生殖系统每个卵巢有五六个卵巢。组织学数据显示P的卵巢。parallelus parallelus是 panoistic 类型，每个卵巢分为末端细丝、germarium、vitellarium 和 pedicel。积累在卵母细胞细胞质中的卵黄颗粒的组织化学特征也已被鉴定。在卵母细胞发育阶段，在卵质中观察到逐渐变大的卵黄颗粒的积累。组织化学染色显示这些蛋黄颗粒具有蛋白质和碳水化合物结构。
