The system consists of paired ovaries, lateral and common oviducts, a spermatheca, and a genital chamber. Each ovary contains two long, telotrophic-meroistic ovarioles, divided into the terminal filament, germarium, vitellarium, and pedicel. The germarium houses trophocytes and young oocytes, while the vitellarium contains oocytes at various developmental stages. Previtellogenic oocytes feature a cylindrical follicular epithelium without yolk. In contrast, vitellogenic oocytes possess a cuboidal epithelium and yolk-filled ooplasm; during the choriogenic stage, the follicular epithelium becomes squamous, and the ooplasm becomes densely packed with yolk. Histological differences in epithelium and muscle layers distinguish the lateral and common oviducts. Eggs, measuring approximately 0.2\u2005mm by 0.3\u2005mm, are laid on alfalfa stems. Initially whitish, they darken to black during embryonic development. SEM analysis revealed a porous endochorion and an exochorion characterized by transverse and longitudinal lamellar air spaces, likely facilitating gas exchange. These morphological and histological findings offer critical insights into the reproductive biology of H. postica, providing a structural basis for improving pest management and biological control interventions.<\/jats:p>","DOI":"10.1093\/mam\/ozag074","type":"journal-article","created":{"date-parts":[[2026,7,28]],"date-time":"2026-07-28T11:19:48Z","timestamp":1785237588000},"source":"Crossref","is-referenced-by-count":0,"title":["The Ovarian Structure and Vitellogenesis, Spermatheca, and Egg in the Alfalfa Weevil,\n                    <i>Hypera postica<\/i>\n                    (Gyllenhal, 1813) (Coleoptera: Curculionidae)"],"prefix":"10.1093","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7137-8631","authenticated-orcid":false,"given":"Nurcan","family":"\u00d6zyurt Ko\u00e7ako\u011flu","sequence":"first","affiliation":[{"name":"Department of Biology, Faculty of Science, Gazi University , Ankara 06500 ,","place":["T\u00fcrkiye"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8206-8855","authenticated-orcid":false,"given":"Hicret","family":"Arslan","sequence":"additional","affiliation":[{"name":"Department of Biology, Faculty of Science, Gazi University , Ankara 06500 ,","place":["T\u00fcrkiye"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7402-1360","authenticated-orcid":false,"given":"Selami","family":"Candan","sequence":"additional","affiliation":[{"name":"Department of Biology, Faculty of Science, Gazi University , Ankara 06500 ,","place":["T\u00fcrkiye"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,7,28]]},"reference":[{"issue":"2","key":"2026072807194266300_ozag074-B1","doi-asserted-by":"publisher","first-page":"177","DOI":"10.1016\/j.sjbs.2010.02.012","article-title":"Morphology of the egg shell and the developing embryo of the Red Palm Weevil, Rhynchophorus ferrugineus (oliver)","volume":"17","author":"Al-Dosary","year":"2010","journal-title":"Saudi J Biol Sci"},{"key":"2026072807194266300_ozag074-B2","doi-asserted-by":"publisher","first-page":"34","DOI":"10.1080\/00779962.1989.9722561","article-title":"Functional anatomy of the reproductive system of Listronotus bonariensis (kuschel)","volume":"12","author":"Barker","year":"1989","journal-title":"N Z Entomol"},{"key":"2026072807194266300_ozag074-B3","doi-asserted-by":"publisher","first-page":"65","DOI":"10.1186\/s41938-018-0067-7","article-title":"Efficacy of some local isolates of the fungus Beauveria bassiana (balsamo) vuillemin on the alfalfa weevil Hypera postica (gyllenhal) (Coleoptera: Curculionidae) larvae, under laboratory conditions","volume":"28","author":"Baysal","year":"2018","journal-title":"Egypt J Biol Pest Control"},{"issue":"2","key":"2026072807194266300_ozag074-B4","doi-asserted-by":"publisher","first-page":"242","DOI":"10.1093\/aesa\/30.2.242","article-title":"Structure of the reproductive system of the pecan weevil (Curculionidae)","volume":"30","author":"Bissell","year":"1937","journal-title":"Ann Entomol Soc Am"},{"issue":"1","key":"2026072807194266300_ozag074-B5","doi-asserted-by":"publisher","first-page":"403","DOI":"10.3844\/ajabssp.2008.403.409","article-title":"Growth performance of the Red-Stripe Weevil Rhynchophorus schach Oliv.
