Morphology of the Female Reproductive System in Carpocoris mediterraneus Tamanini, 1958 (Heteroptera: Pentatomidae)

“…The oocytes, which complete their development in the ovarioles, fall into the pedicel and are released to the common oviduct via the lateral oviduct. This situation is also seen in insect orders, including Heteroptera (Adams, 2001; Lalitha et al, 1997; Özyurt et al, 2013; Mattison et al, 2017; Özyurt Koçakoğlu et al, 2019; Özyurt Koçakoğlu, 2020).…”

“…M. pini (Matsucoccidae) contains 1–6 oocytes (Szklarzewicz et al, 2014). There are 3–6 oocytes in Megamelus scutellaris (Delphacidae), E. ventrale (Pentatomidae), L. equestris (Lygaeidae), C. variegatus (Coreidae), P. apterus (Pyrrhocoridae) (Mattison et al, 2017; Özyurt Koçakoğlu, 2020). There are 12–14 oocytes in G. lacustris (Gerridae) (Özyurt Koçakoğlu, 2020).…”

Notes on the female reproductive system of the red‐and‐black froghopper, Cercopis vulnerata Rossi, 1807 (Hemiptera: Cercopidae)‐light and electron microscopy studies

“…As in most hemipteran insects, in C. vulnerata, the terminal filament originating at the far end of each ovariole consisted mainly of connective tissues for linking up all the adjacent ovarioles of each ovary (Figure 2b) (Cheung, 1994;Kartal & Zeybekoğlu, 1999;Mattison et al, 2017;Özyurt Koçakoğlu et al, 2019). As in M. scutellaris (Delphacidae), ovarioles of C. vulnerata were joined by terminal filaments that fused to form a suspensory filament presumably attached to the abdomen wall (Figure 2a,b) (Mattison et al, 2017). In this way, it is ensured that the ovarioles stay in the abdominal cavity certainly (Kartal & Zeybekoğlu, 1999).…”

“…Each ovary of Euscelidium variegatus Kirshbaum (Cicadellidae) consists of usually 7 ovarioles (Cheung, 1994). In Megamelus scutellaris Berg, 1883 (Delphacidae), each ovary has 11 to 13 ovarioles (Mattison et al, 2017). Each ovary of Trioza erytreae (Del Guercio) (Psyllidae) comprises 25 to 30 ovarioles (Blowers & Moran, 1967).…”

“…Hemiptera is an economically important and widely distributed class of insects. There are various publications on the morphology of the reproductive system of these insects (Blowers & Moran, 1967; Cheung, 1994; Elelimy et al, 2017; Kartal & Zeybekoğlu, 1999; Mattison et al, 2017; Özyurt et al, 2013; Özyurt Koçakoğlu et al, 2019; Souza et al, 2014). However, there is no study of the family Cercopidae is considered.…”
