Aspects of histophysiology of the spermathecal gland of <i>Sitophilus granarius</i> (L.) (Coleoptera)

Abstract

Histochemical tests indicated the presence of glycogenous polysaccharides, glycoproteins, and phospholipid material in the spermathecal gland and its secretion, which, it is suggested, supplies the spermatozoa with nutritive substances and, possibly, energy during storage within the spermatheca of the female weevil.
