Molecular characterization of Psyttalia lounsburyi, a candidatebiocontrol agent of the olive fruit fly, and its Wolbachia symbionts asa pre-requisite for future intraspecific hybridization

Abstract

Numerous arthropod species are genetically differentiated across their distribution area. Diversifying the geographical origins of a biocontrol agent species can be used to favour their perennial establishment by the sampling of pre-adapted genotypes and/or the production of new genotypes through hybridization. Hybridization can be nevertheless challenged by reproductive isolations induced by some common microbial endosymbionts. In this study, we aimed at characterizing (i) the genetic diversity of six populations of Psyttalia lounsburyi (Hymenoptera: Braconidae), a candidate biocontrol agent of the olive fruit fly Bactrocera oleae (Diptera: Tephritidae) and (ii) the diversity of their Wolbachia endosymbionts. Both mitochondrial and microsatellite markers evidence clustering between the South African population and several Kenyan/Namibian populations. The survey of the Wolbachia also distinguished two main variants with a spatial heterogeneity in the infection status. All these results are discussed in the context of the use of these P. lounsburyi populations for hybridization and further field releases.
