“…Oogonia later transform into young oocytes. Young oocytes are replaced by mature oocytes while they progress throughout the ovary (along the vitellarium region) (Amutkan Mutlu, 2021; Amutkan Mutlu et al, 2021). Follicular epithelial cells initially show a single-layered cubic epithelium, but as follicle maturation continues, they begin to thicken (Figs.…”

“…Morphologically, some insects’ species are reported to have four regions of ovariole including the terminal filament, the germarium, the vitellarium, and the stalk or calyx (Yamany, 2012; Mohamed et al, 2015). In I. nervosa , only three regions are distinguished including the terminal filament, the germarium, and the vitellarium, which was mentioned by Michel & Terán (2017), Amutkan Mutlu (2021), and Amutkan Mutlu et al (2021).…”

“…The number of ovarioles ranges from 60 to 64 in Segestidea novaeguineae (Brancsik, 1897) (Orthoptera, Tettigoniidae) (Solulu et al, 1998). 15–20 ovarioles were seen in Poecilimon cervus (Orthoptera, Tettigoniidae) (Polat, 2016), and this number varied from 9 to 12 ovarioles in Poecilimon ataturki Ünal, 1999 (Orthoptera, Tettigoniidae) (Amutkan Mutlu et al, 2021). Similarly, in I. nervosa , there are approximately 10–15 ovarioles in each ovary.…”

This study was conducted to assess the morphology of eggs and histology of the ovaries in female Isophya nervosa Ramme, 1931 (Orthoptera: Tettigoniidae). While the egg morphology of I. nervosa was studied and examined by a stereomicroscope, a light microscope, and a scanning electron microscope, respectively, the morphology and histology of the ovary of this species were studied and examined by a stereomicroscope, a light microscope, a scanning electron microscope, and a transmission electron microscope, respectively. We found that the adult female had two pairs of ovaries, lateral oviduct, common oviduct, and spermatheca. Morphological study of the ovariole revealed that it is categorized under panoistic type of ovariole which is divided into three regions, the terminal filament, the germarium, and the vitellarium. We also observed that the eggs in I. nervosa have an ellipsoidal shape and are brown in color. Three different layers such as extrachorion, exochorion, and endochorion were observed. When the egg morphology is examined, it is understood that the surface pattern of the egg and the features of the micropylar areas may be distinguishing characters at the subfamily level, in addition to known classical taxonomic characters.
