我们研究了2株沃尔巴克氏体细菌的传播效率，导致细胞质不相容性的白纹伊蚊野外种群的聚合酶链反应测定。我们发现泰国的大陆和岛屿人口被A组和B组细菌双重感染。在320只沃尔巴克氏体阳性的成年蚊子中，97.5%被两组感染。每个沃尔巴克氏体群的单个感染个体几乎数量相等。从80头母猴中筛选出550头子代，A群Wolbachia的传播效率为96.7%，B群Wolbachia的传播效率为99.6%。没有将两种沃尔巴克氏体感染都传播给所有后代的母亲比那些具有完美传播保真度的母亲体型要大得多。我们讨论了我们的研究结果有关的前景，使用沃尔巴克氏体作为一种基因驱动机制。
We examined the transmission efficiency of 2 strains of Wolbachia bacteria that cause cytoplasmic incompatibility in field populations of Aedes albopictus by polymerase chain reaction assay. We found mainland and island populations throughout Thailand to be superinfected with group A and B bacteria. Of 320 Wolbachia-positive adult mosquitoes, 97.5% were infected with both groups. Single infected individuals of each Wolbachia group were encountered in nearly equal numbers. We screened 550 offspring from 80 field-collected mothers and found the transmission efficiency of group A Wolbachia to be 96.7% and that of group B Wolbachia to be 99.6%. Mothers that did not transmit both Wolbachia infections to all of their offspring were significantly larger in size than those with perfect transmission fidelity. We discuss our findings in relation to the prospects of the use of Wolbachia as a gene-driving mechanism.
