Popis: International audience; Hymenopterans under single-locus complementary sex determination (sl-CSD) face inbreeding costs due to this sex determination mode. Under sl-CSD, homozygote eggs at the sl-CSD locus usually develop into unviable or sterile diploid males. Production of such costly males increases when sib-mating happens because related individuals share half of their genome. In the hymenopteran Venturia canescens (a solitary parasitoid wasp), diploid males are sterile, leading to fitness costs through genetic incompatibility between parents. Whereas the costs of producing diploid males and behavioural strategies that would reduce such costs have been studied in females, the potential fitness costs faced by males have not. Here, we aimed to investigate fitness costs that males endure after a single sib-mating and tested whether they have the ability to avoid sib-mating through kin recognition. Our results show that males have a reduced fitness (i.e. they produce fewer daughters) when mating with their sibs. We also show that males have the ability to distinguish between non-sib and sib females (i.e. kin). They use chemical marks emitted by the females to discriminate kin from non-kin. We discuss the evolution of kin recognition in males in the context of mate choice for genetic compatibility
