社会性昆虫社会被认为是由许多极其合作的个体组成的。虽然传统上认为员工的行为是利他的，但最近的研究表明员工的行为更加自私。其中一个例子是种内社会寄生，即工蚁侵入同种群体并产生由不相关的宿主工蚁抚养的雄性后代。这种种内寄生现象已在蜜蜂（Apis cerana 和 A. florea）和 Bombus terrestris 的“半野生”熊蜂群体中得到报道。在这里，我们报告了熊蜂 B. deuteronymus 的“野生”群体中工蜂的种内社会寄生行为。研究的 11 个中须芽孢杆菌菌落中，有 3 个被非生育工蚁入侵，其中 75% 的工蚁具有繁殖能力，并产生了 19% 的成年雄性。入侵的非产工产生的雄性明显多于常驻的产工，而且非产工没有受到产工的歧视。
Social insect societies are considered to be composed of many extremely cooperative individuals. While workers are traditionally believed to behave altruistically, recent studies have revealed behaviors that are more selfish. One such example is intraspecific social parasitism, where workers invade conspecific colonies and produce male offspring that are reared by unrelated host workers. Such intraspecific parasitism has been reported in honeybees (Apis cerana, and A. florea) and "semi-wild" bumblebee colonies of Bombus terrestris. Here we report on intraspecific social parasitism by workers in "wild" colonies of the bumblebee B. deuteronymus. Three of the 11 B. deuteronymus colonies studied were invaded by non-natal workers, of which 75% became reproductive and produced 19% of the adult males. The invading non-natal workers produced significantly more males than resident natal workers and the non-natal brood was not discriminated against by the natal workers.
