| Spermologus rufus Boheman (Coleoptera: Curculionidae) is an insect which attacks cacao nuts, oleaginous pits and Araucaria angustifolia (Bert.) Kuntze seeds. In this study the reproductive behavior of S. rufus was investigated to provide useful knowledge to support control measures of this insect. Research was carried out under laboratory conditions. Twenty-two couples of newly emerged adults were individualized in Wheaton flasks containing A. angustifolia seeds for oviposition and feeding. Mating was observed every day until the insects died.
