Structure of the Male Reproductive System and Spermatogenesis of Codophila varia (Fabricius, 1787) (Heteroptera: Pentatomidae) by Light and Scanning Electron Microscopy
Keywords:Testes, vas deferens, seminal vesicle, ejaculatory bulb, SEM (Scanning Electron Microscope)
Structural features of the male reproductive system in Codophila varia (Fabricius, 1787) were investigated utilizing both light and scanning electron microscopes. Microscope examinations showed that the male reproductive system in C. varia consists of two testis, two vas deferentia, two seminal vesicles, two accessory glands, two ectodermal sacs, ejaculatory bulb, ejaculatory duct and aedeagus. The male reproductive tract, showed each testes with intense red coloration in slightly oval structure, with seven follicles. The vas deferens and seminal vesicle were similar in color to the testes and formed long filaments. Vas deferens and seminal vesicle insert on the anterior medial portion of the ejaculatory bulb. The ejaculatory duct extends from the base of the ejaculatory bulb to the aedeagus. Also, structural similarities in the male reproductive systems of C. varia and some other Hemipteran species are discussed.
