1. 几种蜜蜂的工蜂会前往同种蜂巢（“漂流”），进入其中，并在其中产生雄性后代，从而充当种内社会寄生虫。这为蜜蜂的繁殖行为和空间生态学增加了一个新的维度，但在田间尺度上（即田间条件下的自然巢密度）发生漂移的程度尚不清楚。2．以熊蜂Bombus terrestris(Linnaeus)为模型系统，我们试图确定野外规模工蜂漂流率以及野生蜂巢中潜在漂流工蜂的频率。3．一项对 27 个群体进行的实地实验表明，工蚁会前往最远 60 米远的同种巢穴并被其接受，尽管巢穴内被接受的漂流工蚁数量随着距离的增加而显着下降。漂流入巢率较高，明显超过漂流接受率。 4．对英国大伦敦地区野外采集的 8 个工蚁巢进行的微卫星基因分型表明，极少数 (3%) 的工蚁不是同巢工蚁的亲姐妹，因此很可能是漂泊工蚁。5。因此得出的结论是，工蜂可以在野外规模上漂流到同种巢穴，并证实成功的漂流发生在自然种群中。漂移似乎是一种自然但低频的行为 B.地球工人获得直接健身。
1. Workers in several bee species travel to conspecific nests (‘drifting’), enter them, and produce male offspring inside them, so acting as intra‐specific social parasites. This adds a new dimension to bees' reproductive behaviour and spatial ecology, but the extent to which drifting occurs over field scales, i.e. at natural nest densities in field conditions, has been unclear.2. Using the bumble beeBombus terrestris(Linnaeus) as a model system, we sought to determine rates of worker drifting at field scales and the frequency of potential drifter workers in wild nests.3. A field experiment with 27 colonies showed that workers travelled to, and became accepted in, conspecific nests that were up to 60 m away, although the number of accepted drifter workers within nests fell significantly with distance. The rate at which nests were entered by drifters was relatively high and significantly exceeded the rate at which drifters became accepted.4. Microsatellite genotyping of eight field‐collected nests from Greater London, U.K., showed that a low frequency (3%) of workers were not full sisters of nestmate workers and hence were likely to have been drifter workers.5. It is therefore concluded that workers can drift to conspecific nests over field scales and confirmed that successful drifting occurs in natural populations. Drifting appears to be a natural but low‐frequency behaviour permittingB. terrestrisworkers to gain direct fitness.
