    For some time now I have been studying different aspects of the interactions among plants, herbivorous insects and the natural enemies of these insects. In a first study I examined the direct and indirect effect of several plant species on the interaction between the Cabbage Butterfly, Pieris rapae, and the larval parasitoid, Cotesia glomerata. The results of this work revealed the importance plant traits for parasitoid success, which inspired me to further pursue a better understanding of these interactions in a natural system. Our principle model system comprises beans, bruchid beetles and their natural enemies, which is used to test several ecological and evolutionary hypotheses in a natural setting. I have established a research group in which students from Neuchâtel and Mexico examine the consequences of plant domestication and the effects of plant variation on tri-trophic interactions. The main objective of our research is to elucidate the relative importance of proximal factors in shaping the evolution of tri-trophic interactions.
