  abstract = {{D}issecting the genetic basis of intraspecific variations in life history traits is essential to understand their evolution, notably for potential biocontrol agents. {S}uch variations are observed in the endoparasitoid {C}otesia typhae ({H}ymenoptera : {B}raconidae), specialized on the pest {S}esamia nonagrioides ({L}epidoptera : {N}octuidae). {P}reviously, we identified two strains of {C}. typhae that differed significantly for life history traits on an allopatric host population. {T}o investigate the genetic basis underlying these phenotypic differences, we used a quantitative trait locus ({QTL}) approach based on restriction site-associated {DNA} markers. {T}he characteristic of {C}. typhae reproduction allowed us generating sisters sharing almost the same genetic content, named clonal sibship. {C}rosses between individuals from the two strains were performed to generate {F}2 and {F}8 recombinant {CSS}. {T}he genotypes of 181 clonal sibships were determined as well as the phenotypes of the corresponding 4,000 females. {I}nformative markers were then used to build a high-quality genetic map. {T}hese 465 markers spanned a total length of 1,300 c{M} and were organized in 10 linkage groups which corresponded to the number of {C}. typhae chromosomes. {T}hree {QTL}s were detected for parasitism success and two for offspring number, while none were identified for sex ratio. {T}he {QTL}s explained, respectively, 27.7% and 24.5% of the phenotypic variation observed. {T}he gene content of the genomic intervals was investigated based on the genome of {C}. congregata and revealed 67 interesting candidates, as potentially involved in the studied traits, including components of the venom and of the symbiotic virus (bracovirus) shown to be necessary for parasitism success in related wasps.},
