Plants dominate the biomass of terrestrial ecosystems and lie at the centre of most community interaction webs. Consequently, changes in plant phenotypes induced by manipulative parasites have potentially profound implications for ecological communities and ecosystems. But manipulation of plants has rarely been a major focus of the broader literature on host manipulation by parasites. This chapter provides an overview of some of the most prominent and best-studied examples of manipulation involving plant–insect interactions, including both systems in which insects themselves are manipulators of their host plants (as in the case of gall-inducing herbivores) and systems in which the interaction between plant and insect is the target of manipulation (as in the case of manipulation of host plants by insect-vectored pathogens).Less

This chapter articulates subindividual variability as an individual property in the format of the Haldane-Roy conjecture that describes within-plant variability in organ characteristics denoting a significant shift of opinion about the importance of a phenomenon. The verification of the Haldane-Roy conjecture, and its reinforcement by indications of a genetic basis of within-plant variation, should impel us to change the ways in which the individual plant phenotypes are characterized. Within-plant variance should be granted a descriptive value of the phenotype similar to the value traditionally conferred on the within-plant mean of organ trait values. Hence, acceptance of the Haldane-Roy conjecture opens the way to examining variation among characters, among species, and among populations of the same species, also from the perspective of their levels of within-individual variability.Less
