Several parthenogenetic species of broad-nosed weevils exist, some of them of economic importance because of their pest status. Screening of the maternally inherited Wolbachia bacterium in 29 weevils of the tribe Naupactini, using multilocus sequence typing allowed us to assess a significant correlation between asexuality and infection, and suggests an involvement of Wolbachia in the origin of this reproductive mode. The nine Wolbachia strains retrieved from the Naupactini belong to the B supergroup. Phylogenetic analysis of these strains, along with other 23 strains obtained from arthropods and nematodes, supports previous hypotheses that horizontal transfer of Wolbachia amongst species from unrelated taxa has been pervasive.
存在几种孤雌生殖的宽鼻象甲物种，其中一些由于其害虫地位而具有经济重要性。使用多位点序列分型对 Naupactini 族的 29 种象甲进行了母体遗传的沃尔巴克氏体筛选，这使得我们能够评估无性繁殖和感染之间的显著相关性，并表明沃尔巴克氏体参与了这种生殖方式的起源。从 Naupactini 中回收的 9 种沃尔巴克氏体菌株属于 B 超组。对这些菌株以及从节肢动物和线虫中获得的其他 23 种菌株的系统发育分析支持了以前的假设，即沃尔巴克氏体在来自不同分类群的物种之间的水平转移是普遍存在的。
