几种真社会性黄蜂是偏远岛屿的突出入侵者。本文报道中国蜂Polistes chinensis antennalisis原产于东亚，1979年引入新西兰，扩大了其在新西兰的分布。这提供了一个很好的机会来研究最初的瓶颈和随后的扩张对遗传结构的影响。我们分析和比较了本地（日本和韩国）和入侵新西兰人口的遗传结构。虽然94%的个体在两个人群中检测到共享的单倍型，但其余6%的个体仅在三个国家中的一个国家中发现了私人单倍型。微卫星位点的遗传变异在新西兰低于在本土国家，在新西兰的遗传结构是明显不同于在其本土范围。在新西兰检测到产生二倍体雄性和三倍体雌性菌落的频率高于本土国家，表明遗传变异通过遗传瓶颈减少。建议至少有两个独立的引进，和新西兰的假定源区被指定为关东（中央岛）和九州（南岛）在日本。还指出了最初引入后的系列创始人事件。在新西兰，母亲和女儿之间的传播距离估计是日本的两倍。因此，中国对虾在新西兰的引种历史可能是至少两次独立引种的结果，在引种过程中经历了一个瓶颈期，随后从引种点开始种群扩张。
Several eusocial wasps are prominent invaders to remote islands. The paper waspPolistes chinensis antennalisis native to East Asia, was introduced to New Zealand in 1979 and has expanded its distribution there. This provides an excellent opportunity to examine the impacts of an initial bottleneck and subsequent expansion on genetic structure. We analysed and compared the genetic population structures of the native (Japan and South Korea) and invasive New Zealand populations. Although 94% of individuals had shared haplotypes detected across both populations, the remaining 6% had private haplotypes identified in only one of the three countries. The genetic variation at microsatellite loci was lower in New Zealand than in native countries, and the genetic structure in New Zealand was clearly distinct from that in its native range. Higher frequencies of diploid‐male‐ and triploid‐female‐producing colonies were detected in New Zealand than in the native countries, showing the reduction in genetic variation via a genetic bottleneck. At least two independent introductions were suggested, and the putative source regions for New Zealand were assigned as Kanto (central island) and Kyushu (south island) in Japan. Serial founder events following the initial introduction were also indicated. The estimated dispersal distance between mother and daughter in New Zealand was twice that in Japan. Thus, the introduction history ofP. chinensis antennalisin New Zealand is probably the result of at least two independent introductions, passing through a bottleneck during introduction, followed by population expansion from the point of introduction.
