蜜蜂蜂王（Apis）的一妻多夫制会导致一个蜂群中有许多父系（亚科），这可能会导致工蜂之间潜在的利益冲突。这可能是最明显的在女王饲养时，裙带关系的工人行为可能会影响后代的遗传。一些研究已经在欧洲蜜蜂中寻找这种冲突（A。mellifera），但对其他蜜蜂物种的研究仍然缺乏。我们调查了A.通过比较蜂王幼虫和成虫的父系比例，研究了中华大蜡蝉的雌雄关系。我们确定了父系的272名工人和57皇后幼虫使用4个多态性微卫星标记，从无皇后殖民地最初来自四个自然交配皇后正确的殖民地取样。每个群体的父系数量分别为9、12、8和7，低于亚洲大陆的父系数量。我们没有发现成年工人和女王幼虫之间的父系比例的差异。我们的数据既不支持皇室成员的遗传变异，也不支持A.日本樱
Polyandry in honeybee queens (Apis) causes many patrilines (subfamilies) within a colony, which may lead to a potential conflict of interest among workers. This may be most apparent during queen rearing when nepotistic worker behavior could influence the genetics of future generations. Several studies have searched for such conflict in European honeybees (A. mellifera), but studies on other Apis species remain lacking. We investigated the presence of reproductive conflict in A. cerana japonica by comparing the patriline proportion of queen larvae to that of adult workers. We determined the patrilines of 272 workers and 57 queen larvae using four polymorphic microsatellite markers that were sampled from queenless colonies originally derived from four naturally mated queen-right colonies. The number of patrilines in each colony was 9, 12, 8, and 7, respectively, which is lower than that observed in continental Asia. We found no difference in patriline proportion between adult workers and queen larvae. Our data support neither genetic variance for royalty or existence of worker nepotism in A. cerana japonica.
