摘要

沃尔巴克氏体是一种母体遗传的α -变形菌门内共生体，广泛存在于节肢动物和线虫中。细胞质不相容(CI)是节肢动物中最常见的内共生操作，即当感染沃尔巴克氏体的雄性与未感染沃尔巴克氏体的雌性受精时，胚胎存活率降低。本研究通过对双翅蟋蟀(直翅目:灰鼠科)进行内共生菌感染研究和杂交实验，以阐明沃尔巴克氏体对宿主繁殖的影响。所有检测个体均感染了两种沃尔巴克氏体菌株wAsp‐a和wAsp‐f，分别属于超群a和超群f。在感染沃尔巴克氏体和未感染沃尔巴克氏体的品系之间，若虫发育的持续时间和雌性比例没有明显差异。然而，与感染沃尔巴克氏体的雄性与感染沃尔巴克氏体的雌性杂交相比，感染沃尔巴克氏体的雄性与感染沃尔巴克氏体的雌性杂交可使孵化率降低28%。没有沃尔巴克氏体的雌虫产卵量明显低于与感染雄虫或未感染雄虫交配的感染雌虫的产卵量。这些结果表明沃尔巴克氏体诱导长尾弓形虫不完全CI并提高雌性生殖力。由于在C、D和F超群中均未发现与CI相关的同源cifA和cifB基因，因此可以认为长尾弧菌的CI是由a超群的wAsp‐a菌株诱导的。此外，寄生蜂‐a沃尔巴克氏体密度随蛹发育的显著增加可能与CI的调控有关。

期刊介绍： Ecological Entomology publishes top-quality original research on the ecology of insects and related invertebrate taxa. Our aim is to publish papers that will be of considerable interest to the wide community of ecologists who are motivated by ecological or evolutionary theory. The suitability of a manuscript will usually be assessed within 5 days. We publish full-length Original Articles as well as Reviews, Short Communications, Methods and Natural History papers. In Original Articles, we greatly prefer papers that test specific hypotheses and which have a high degree of novelty. All categories aim for innovative contributions that advance the subject of ecological entomology.
