社会性昆虫的特点是分工。蚁后通常控制繁殖，而工蚁则完成与繁殖无关的年龄相关的任务，以维持殖民地。虽然工蜂通常是不育的，但它们可以激活卵巢来生产自己的后代。在极端的情况下，工蜂繁殖会转变为社会寄生，如意大利蜜蜂。这些种内寄生虫占据一个宿主群体，杀死居住的女王，并接管生殖垄断。因为他们表现出女王般的行为，也被同事们当作女王对待，所以他们被称为伪女王。在这里，我们使用脂肪体转录组数据比较了不同时间点寄生虫假皇后和社会工作者的发育。两个互补的分析方法-主成分分析和时间过程分析-导致识别的核心一组基因参与从社会工作者到一个高生育力的寄生pseudoqueen的过渡。比较我们的研究结果与蜂后的基因表达数据的假蜂王揭示了许多相似之处。此外，寄生假蜂王体内存在一系列不同于蜂王和社会工作者的特异转录组变化，这可能是A. M. Capensis。
Social insects are characterized by the division of labor. Queens usually dominate reproduction, whereas workers fulfill nonreproductive age-dependent tasks to maintain the colony. Although workers are typically sterile, they can activate their ovaries to produce their own offspring. In the extreme, worker reproduction can turn into social parasitism as in Apis mellifera capensis. These intraspecific parasites occupy a host colony, kill the resident queen, and take over the reproductive monopoly. Because they exhibit a queenlike behavior and are also treated like queens by the fellow workers, they are so-called pseudoqueens. Here, we compare the development of parasitic pseudoqueens and social workers at different time points using fat body transcriptome data. Two complementary analysis methods-a principal component analysis and a time course analysis-led to the identification of a core set of genes involved in the transition from a social worker into a highly fecund parasitic pseudoqueen. Comparing our results on pseudoqueens with gene expression data of honeybee queens revealed many similarities. In addition, there was a set of specific transcriptomic changes in the parasitic pseudoqueens that differed from both, queens and social workers, which may be typical for the development of the social parasitism in A. m. capensis.
