Ant workers produce males in queenless parts of multi-nest colonies

Giehr, Julia ; Senninger, Lisa ; Ruhland, Katja ; Heinze, Jürgen


Workers of several social insects are capable of gaining direct fitness by laying unfertilized eggs, which then develop into males. However, under queenright conditions, direct reproduction of workers is usually prevented by queen-induced regulatory mechanisms. In nature, some ant colonies inhabit multiple nests sites (polydomy).
