  abstract = {{A}s a result of an intense host-parasite evolutionary arms race, parasitic wasps frequently display high levels of specialization on very few host species. {F}or instance, in braconid wasps very few generalist species have been described. {H}owever, within this family, {C}otesia sesamiae is a generalist species that is widespread in sub-{S}aharan {A}frica and develops on several lepidopteran hosts. {I}n this study, we tested the hypothesis that {C}. sesamiae may be a cryptic specialist when examined at the intraspecific level. {W}e sequenced exon 2 of {C}r{V}1, a gene of the symbiotic poly{DNA}virus that is integrated into the wasp genome and is associated with host immune suppression. {W}e found that {C}r{V}1 genotype was more closely associated with the host in which the parasitoid developed than any abiotic environmental factor tested. {W}e also tested a correlation between {C}r{V}1 genotype and an infection with {W}olbachia bacteria, which are known for their ability to induce reproductive isolation. {T}he {W}olbachia bacteria infection polymorphism was also found as a major factor explaining the genetic structure of {C}r{V}1, and, in addition, the best model explaining {C}r{V}1 genetic structure involved an interaction between {W}olbachia infection and host species. {W}e suggest that {W}olbachia could act as an agent capable of maintaining advantageous alleles for host specialization in different populations of {C}. sesamiae. {T}his mechanism could be applicable to other insect models because of the high prevalence of {W}olbachia in insects.},
