问题：胞质不相容性诱导的沃尔巴克氏体的流行是否在整个蝴蝶种群中传播？假设：沃尔巴克氏体是自我促进的细胞内微生物，感染很容易在宿主群体中传播。日本粉蝶（Eurema hecabe）实地考察地点：在整个日本群岛随机选择32个当地人口。方法：采用诊断PCR方法对1997 ~ 2000年的Wolbachia感染情况进行调查。1992年、1999年和2000年进行了群体间杂交试验，以检测细胞质不亲和性。结论：在日本南部人群中检测到高沃尔巴克氏体频率，但在北方地区未发现感染。在两种主要类型的宿主（棕色和黄色）中发现了诱导细胞质不相容的沃尔巴克氏体，这是生殖隔离的。入侵的细胞质不相容性诱导沃尔巴克氏体进入日本中部人群发生在过去十年中所示的时间数据。我们的数据符合沃尔巴克氏体动力学的标准模型。
Question: Is the prevalence of cytoplasmic incompatibility-inducing Wolbachia spreading throughout butterfly populations? Hypothesis: Wolbachia are self-promoting intracellular microbes and the infection spreads easily among host populations. Organism: Japanese pierid butterfly (Eurema hecabe). Field sites: Thirty-two haphazardly selected local populations throughout the Japanese archipelago. Methods: We surveyed Wolbachia infection from 1997 to 2000 using diagnostic PCR. An inter-population cross-experiment was performed to detect cytoplasmic incompatibility in 1992, 1999 and 2000. Conclusions: High Wolbachia frequencies were detected in southern populations, but no infection was found in the northern parts of Japan. Cytoplasmic incompatibility-inducing Wolbachia was found in the two main types of host (brown and yellow), which are reproductively isolated. The invasion of cytoplasmic incompatibility-inducing Wolbachia into the central Japanese populations has occurred within the last decade as shown by chronological data. Our data fit well with standard models of Wolbachia dynamics.
