Strong cytoplasmic incompatibility caused by Wolbachia was thought to be a speciation mechanism among bean weevils in genus Callosobruchus. Artificial Wolbachia injection and removal experiments with tetracycline showed that Wolbachia did not play a role of speciation among C. analis, C. maculatus, C. rhodesianus, and C. sabinnotetus. On the other hand, Wolbachia removal and reintroducing experiments among 9 strains of C. analis revealed that the CI level became more benign as the length of coevolution between C. analis and Wolbachia was longer. CI levels induced by Wolbachia were products of coevolution between Wolbachia and its hosts in C. analis.

沃尔巴克氏体引起的强细胞质不亲和性被认为是胼胝体属豆象甲物种形成的机制。人工注射和四环素去除沃尔巴克氏体实验表明，沃尔巴克氏体在C. analatus、C. maculatus、C. rhodesianus和C. sabinnotetus中没有起到物种形成的作用。另一方面，对9株分析梭菌沃尔巴克氏体的去除和再引入实验表明，随着分析梭菌与沃尔巴克氏体共同进化的时间越长，CI水平越良性。沃尔巴克氏体诱导的CI水平是沃尔巴克氏体与其寄主共同进化的产物。
