摘要: Inbreeding frequently has a costly impact on fitness, thus selection favoured the evolution of kin recognition and inbreeding avoidance behaviour in many species. As haplodiploid Hymenoptera, bumblebees are susceptible to additional costs due their single-locus complementary sex determination (sl-CSD) system, which means that incest can result production diploid males. Here we test whether Bombus terrestris reproductives able discriminate between non-kin willingness mate is adjusted accordingly. We found B. took significantly longer with siblings compared non-relatives. This indicates this species exhibits uses information determine mating behaviour.
