Figure 1

Illustration of multi-trophic plant–pest interactions mediated by microorganisms focusing on plants, herbivores and entomophagous arthropods. Black, green and orange colors refer to insect, plant (rhizo-, phyllo- and endospheres) and herbivore sources, respectively. Blue and red arrows indicate direct and indirect (through plants) effects on target organisms, respectively, while black arrows illustrate insect origin.
