Summary

This chapter first describes the general effects and mediating mechanisms that root feeders and soil-borne symbionts can exert on the chemical ecology of above-ground plant–herbivore–parasitoid interactions. It then discusses how the growth, development and host selection behaviour of parasitoids can be influenced by these soil-dwelling functional groups. In most empirical studies, the effects on parasitoids appear to be mediated by changes in primary and secondary above-ground plant metabolites and in herbivore-induced plant volatiles (HIPVs), all induced by soil organisms. Finally, the chapter discusses how starting from a reductionist perspective and then expanding the spatial and temporal scales up to the level of communities and ecosystems can contribute to a better understanding of the assemblage and functioning of above–below-ground interactions.
