Loss of Wolbachia infection during colonisation in the invasive Argentine ant Linepithema humile.

abstract：:Wolbachia are symbiotic bacteria that induce a diversity of phenotypes on their numerous invertebrate host species. In the wasp Asobara tabida (Braconidae), each individual harbours three Wolbachia strains: wAtab3, which is required for host oogenesis, and wAtab1 and wAtab2, that do not have this function but induce c...
