We investigated sex allocation in a central European population of the facultatively polygynous ant Leptothorax acervorum. The population-wide sex ratio was found to be quite balanced. with a proportional investment in female sexuals of 0.49. Sex allocation varied considerably between colonies. resulting in split sex ratios. The productivity of colonies was negatively correlated with queen number and positively with colony size. In contrast. the sex ratio (proportional investment in female sexuals) was neither correlated with queen number, colony size, nor total sexual production, but with worker relatedness. The uncoupling of the genetic colony structure and queen number presumably results from frequent queen turnover and colony splitting.
