Plants are often attacked by multiple herbivores simultaneously feeding on different organs. Plants experiencing herbivory on roots and shoots allocate resources for defense to these tissues to fend off the attackers. Plant-mediated interactions of aboveground and belowground herbivores can impact growth and survival for all organisms involved, but outcomes are often inconsistent depending on the type of herbivores feeding above- and belowground. We describe a meta-analysis investigating the effects of nematodes on aboveground insect herbivores and how these interactions change depending on feeding sub-guild and environmental context, and how they influence plant chemical defense and natural enemy attraction and retention. This meta-analysis gives us a better understanding of the mechanisms driving plant-mediated interactions.
