“…However, two types of glands are classified in the accessory glands of P. parallelus parallelus (Polat et al, 2020). In Sinopanorpa tincta (Navas, 1931) (Mecoptera: Panorpidae) and Tropisternus collaris (Fabricius, 1775) (Coleoptera: Hydrophilidae), there are two types of accessory glands (Lyu & Hua, 2017;Araújo et al, 2021). In this study, we observed two types of accessory glands in B. turkiyae.…”

“…The accessory glands play some crucial roles in the reproductive system in insects, such as regulating sperm activity, formation of spermatophores, production of mating plugs, alterations on sperm bundles, promoting female to oviposition, and preventing females from accepting other males (Viscuso et al, 2001;Colonello & Hartfelder, 2005;Braswell et al, 2006;Marchini et al, 2009;King et al, 2011;Lyu & Hua, 2017;Polat et al, 2019Polat et al, , 2020.…”

“…Along with the functions of the testis and accessory glands, some qualifications of them, such as shape, size, number, and the area where they connect to the reproductive system can vary among different insect groups (Liu et al, 2005;Gomes et al, 2012;Marchini et al, 2012;Dallai et al, 2014;Gullan & Cranston, 2014;Lyu & Hua, 2017;Polat et al, 2019Polat et al, , 2020. Besides, sperm structure and morphology in insects also show great diversity (Kotzé et al, 2019).…”

There are many morphological and histological studies in the world to investigate the structure of the external and internal organs of insects. These studies not only serve to illuminate the biology of insect species, but also to reveal taxonomic relationships. For this purpose, the detailed structure of the testis and accessory glands that are the main organs of the male reproductive system of Bolua turkiyae Ünal, 1999 (Orthoptera: Tettigoniidae) was searched with a light microscope, scanning electron microscope, and transmission electron microscope techniques in 2019-2020 in Gazi University, Prof. Dr. Zekiye Suludere Electron Microscope Center in this study. B. turkiyae is an endemic species distributed around Bolu province in Turkey. The reproductive system of male B. turkiyae is comprised of testis, vas deferens, and accessory glands. When the cross-sections of the oval and yellow testis were examined, it was observed that they contain many follicles. There are cysts in these follicles that have the developmental stages of the sperm. From the distal ends of the follicles to the proximal ends, the germarium, growth zone, maturation zone, and transformation zone are located respectively. In these stages, spermatogonium, spermatocyte, spermatids, and finally spermatozoa are formed. Accessory glands are hollow tubular structures of two different sizes and diameters. Single-layered cubic or pyramidal cells surround the lumen in both groups of accessory glands. It is hoped that these new data will contribute to our understanding of the structure of the male reproductive system of B. turkiyae.

“…A similar constitution led us to conclude that secretion in C. pallens accessory gland belongs to a common apocrine mechanism in insects, which is pooled from epithelial cells to the tubular lumen backed by the apical membrane [ 27 – 29 ]. However, insect accessory glands may vary strikingly among taxa based on their detailed structures [ 2 , 5 – 11 , 13 , 14 , 30 , 31 ]. In the present study, the C. pallens accessory gland showed distinctive traits, particularly the presence of many circular and longitudinal muscle fibers (Fig.…”

“…Morphological and ultrastructural features of the genital system also offer convincing evidence for studies in systematics, reproductive biology, and evolutionary biology [ 2 ]. Over the past several decades, studies on insect reproductive systems have mainly focused on Diptera, Hemiptera, Coleoptera, Hymenoptera, and rare insect orders such as Mecoptera and Zoraptera [ 2 , 4 , 6 – 14 ]. Neuropterans include several important predatory species with a promising application potential in the biocontrol of insect pests.…”

Background Chrysopa pallens is one of the most beneficial and effective natural predators, and is famous for its extensive distribution, wide prey spectrum, and excellent reproductive performance. This study examined the anatomy and fine structure of the C. pallens reproductive system and spermatogenesis. Results The male reproductive system of C. pallens comprises a pair of testes, a vas deferens, seminal vesicles, accessory glands, and short ejaculatory ducts. The testes were already mature on the day of emergence, but the accessory glands did not mature until 5 days post-emergence. In early spermatids, the flagellum had an axoneme on one side of the two mitochondrial derivatives. The nucleus was surrounded by parallel crystalline and paracrystalline materials. The spermatid envelope extends towards the paracrystalline material in a tail-shaped wing. In mature spermatids, the axoneme is located between the two accessory bodies and mitochondrial derivative sets. The parallel-crystalline and paracrystalline materials disappeared. In the testes, the wall of seminal cysts consists of a layer of epithelium, a muscular-connective sheath, and several vesicles of different sizes. The mature seminal cysts contained 128 spermatozoa. The accessory gland is composed of six parts: ventral papilla-like protuberance, anterior glandular lobe, lateral glandular lobe, seminal cyst, posterior kidney-shaped lobe, and posterior papilla-like protuberance. Muscle fibers and secretory granules are extensive. Conclusions This study provides information on the reproductive system of C. pallens and offers a resource for taxonomy and reproductive biology.
