  abstract = {{T}he parasitoid lifestyle represents one of the most diversified life history strategies on earth. {T}here are however very few studies on the variables associated with intraspecific diversity of parasitoid insects, especially regarding the relationship with spatial, biotic and abiotic ecological factors. {C}otesia sesamiae is a {S}ub-{S}aharan stenophagous parasitic wasp that parasitizes several {A}frican stemborer species with variable developmental success. {T}he different host-specialized populations are infected with different strains of {W}olbachia, an endosymbiotic bacterium widespread in arthropods that is known for impacting life history traits, notably reproduction, and consequently species distribution. {I}n this study, first we analyzed the genetic structure of {C}. sesamiae across {S}ub-{S}aharan {A}frica, using 8 microsatellite markers. {W}e identified five major population clusters across {S}ub-{S}aharan {A}frica, which probably originated in the {E}ast {A}frican {R}ift region and expanded throughout {A}frica in relation to host genus and abiotic factors, such as {K}oppen-{G}eiger climate classification. {U}sing laboratory lines, we estimated the incompatibility between the different strains of {W}olbachia infecting {C}. sesamiae. {W}e observed that incompatibility between {W}olbachia strains was asymmetric, expressed in one direction only. {B}ased on these results, we assessed the relationships between the direction of gene flow and {W}olbachia infections in the genetic clusters. {W}e found that host specialization was more influential on genetic structure than {W}olbachia-induced reproductive incompatibility, which in turn was more influential than geography and current climatic conditions. {T}hese results are discussed in the context of {A}frican biogeography, and co-evolution between {W}olbachia, virus parasitoid and host, in the perspective of improving biological control efficiency through a better knowledge of biological control agents' evolutionary ecology.},
