The Asian tiger mosquito, Aedes albopictus (Skuse), is a known vector of dengue in South America and Southeast Asia. It is naturally superinfected with two strains of Wolbachia endosymbiont that are able to induce cytoplasmic incompatibility (CI). In this paper, we report the strength of CI expression in crosses involving field-caught males. CI expression was found to be very strong in all crosses between field males and laboratory-reared uninfected or wAlbA infected young females. In addition, crossing experiments with laboratory colonies showed that aged super-infected males could express strong CI when mated with young uninfected or wAlbA infected females. These results provide additional evidence that the CI properties of Wolbachia infecting Aedes albopictus are well suited for applied strategies that seek to utilise Wolbachia for host population modification.
亚洲虎蚊，白纹伊蚊（Skuse），是南美洲和东南亚已知的登革热传播媒介。它自然感染了两种沃尔巴克氏体共生菌菌株，能够诱导细胞质不亲和（CI）。在本文中，我们报告了涉及野外捕获雄性蚊子的杂交中CI表达的强度。发现在野外雄性蚊子与实验室饲养的未感染或感染wAlbA的年轻雌性蚊子之间的所有杂交中，CI表达都非常强烈。此外，实验室群体的杂交实验表明，年老的超级感染雄性蚊子与年轻的未感染或感染wAlbA的雌性蚊子交配时，能够表达强烈的CI。这些结果提供了额外的证据，表明感染白纹伊蚊的沃尔巴克氏体的CI特性非常适合旨在利用沃尔巴克氏体来改变宿主种群的应用策略。
