Morphology of the Female Receptaculum Seminis of Euschistus heros (FABRICIUS, 1798) (INSECTA: HEMIPTERA: PENTATOMIDAE).

Euschistus heros (Fabricius, 1798) (Heteroptera: Pentatomidae) is a soybean pest in Brazil. It has a reproductive success that may be associated with the female receptaculum seminis or spermatheca, a reproductive organ for spermatozoa storage until the oocyte fertilization. This study describes the anatomy and histology of the female receptaculum seminis in E.
