通过分析来自14个巢的20个工蜂的4个DNA微卫星位点，研究了欧洲大黄蜂Vespa crabro的蚁后交配频率。发现蜂王主要是单交配（9/14），尽管双交配（4/14）和三交配（1/14）也发生过。对于大多数多次交配的蚁后来说，父权关系明显偏向于大多数雄性平均抚养80%的雌性后代。种群有效交配频率低（1.11），姊妹亲缘度高（0.701 +/- 0.023 SE）。Vespa的低有效交配频率与其他Vespa的数据相结合，表明该群体的父权频率很高。分析了未检测到父亲的一些问题，其中女王没有采样或与雄性共享等位基因。
Queen mating frequency was studied in the European hornet, Vespa crabro, by analyzing four DNA microsatellite loci in 20 workers from each of 14 nests. Queens were found to be predominantly singly mated (9/14), although double (4/14) and triple mating (1/14) also occurred. For most multiply mated queens, paternity was significantly biased with the majority male fathering on average 80% of the female offspring. The population-wide effective mating frequency was therefore low (1.11), and sister-sister relatedness high (0.701 +/- 0.023 SE). Low effective mating frequency in Vespa in combination with data from other vespines, suggests that high paternity frequency is derived in the group. Some problems with the non-detection of fathers, where the queen was not sampled or shared alleles with males, are analyzed.
