International audience; 1. The ability of parasitoid females to perceive chemical traces left by theirhosts is of utmost importance in the host location process. The behaviours involved insuch ability have thus most likely been promoted by natural selection in the course ofthe evolutionary time. For this to happen, however, there must be signicant geneticvariation in natural populations on which natural selection could act.2. Using the isofemale line method and motion analysis, we detected signicantintra-population genetic variation for several walking behaviour traits of the eggparasitoid Trissolcus brochymenae (Hymenoptera: Scelionidae) females responding tochemical traces left by its host Murgantia histrionica (Heteroptera: Pentatomidae).3. Besides opening new avenues of research on the reproductive strategies, behaviour,and biological control potential of parasitoid wasps, these results also have implicationsfor understanding their life-history evolution in general
