Histomorphology of the Male Reproductive System and Spermatogenesis of Phyllobius (Ectomogaster) fulvago Gyllenhal, 1834 (Coleoptera, Curculionidae): A Light and Scanning Electron Microscope Study

Abstract

Abstract: The morphology and histology of the male reproductive system of Phyllobius fulvago were described and discussed in relation to other Coleoptera species. The results show that Ph. fulvago has two-lobed flower-shaped arranged testes, each lobe with fourteen follicles. There are two types of glands in the male reproductive system in Ph. fulvago: tubular accessory glands and lobed prostate glands. © 2021, Pleiades Publishing, Ltd.
