Abstract：
:The study of copulation and the control of egg production in the blood-feeding insect, Rhodnius prolixus, continues to offer a fertile ground for the cultivation of new insights into the physiological processes associated with reproduction. We begin this paper by describing the male organs of copulation showing that the aedeagus contains a structure which may serve as part of a pumping mechanism or valve to enable the male to fully pack the vagina with his secretions. We then summarize previously published work which identifies possible sensory and chemical aids that can be used by the male as he forms a naked spermatophore within the vagina of the female. With respect to the control of egg production, published anatomical and endocrinological experiments give rise to the intriguing possibility that a vascular portal system exists in the head of this insect, and that this system explains why circulation is required for egg production. By documenting the steps taken by the male during copulation, and by providing a new paradigm to explain the control of egg production, this paper identifies some assumptions that need verification, and offers a foundation upon which future scientists can explore reproductive physiology in this incredible bug.
