作为一个整体，女王交配频率与整个一雌蚂蚁物种的成熟群体大小相关。然而，最近在阿塔和Acromyrmex切叶蚁之间的比较发现了相反的趋势。我们测试了这个结果是否可以复制的阿塔sexdens，使用一个新的。用微卫星标记分析六个幼蚁群的蚁后和工蚁后代。我们发现所有的蚁后都进行了多次交配，并使用了至少2-3个雄性的精子。这一结果与以前的研究结果相当。阿塔colombica和似乎证实，女王交配频率阿塔低于Acromyrmex。
Queen mating frequency is correlated with mature colony size across monogynous ant species as a whole. However, recent comparisons between Atta and Acromyrmex leafcutter ants found an opposite trend. We tested whether this result could be reproduced for Atta sexdens, using a new. Atta colombica microsatellite marker to analyse queens and worker offspring from six young colonies. We found that all queens had mated multiply and used sperm from at least 2-3 males. This result is comparable to previous findings for. Atta colombica and seems to confirm that queen mating frequency in Atta is lower than in Acromyrmex.
