We examined the effect of queen size on the probability of new colony establishment in the ant Pogonomyrmex occidentalis. Large queens are significantly more likely to survive than small queens through the initial stages of colony founding. These differences in individual fitness correlates have corresponding effects on colony fitness. In species in which individual queens vary in fitness, sexual allocation ratios should incorporate the individual fitness functions.
我们研究了蚁后体型对西方收获蚁建立新蚁群概率的影响。在蚁群建立的初始阶段，大型蚁后比小型蚁后存活的可能性显著更高。个体适合度的这些差异对蚁群适合度有相应影响。在蚁后个体适合度存在差异的物种中，性别分配比例应纳入个体适合度函数。
