Summary
Anatomical and histological study of the female reproductive system in the Sitophilus granarius (Coleoptera, Cucurlionidae).
Multiplication and differentiation of the oocytes and nurse cells are carried out in the pupa. The oocytes stock is definitive at metamorphosis. The ovarioles are to be connected with the telotrophic type but the nutritive cords only assure the beginning of the oocytes vitellogenesis.
Vagina and bursa copulatrix have no secretory activity but the paired oviducts behave like glandulary organs; this can be brought together with Acridoidea case. The structure of a glandulary formation associated to the spermatheca is studied.
