Abstract

Beneficial microbes induce resistance in plants (MIR), imposing both lethal and sublethal effects on herbivorous insects. We argue that herbivores surviving MIR carry metabolic and immunological imprints of MIR with cascading effects across food webs. We propose that incorporating such cascading effects will strongly enhance the current MIR research framework.

Keywords: MIR-imprint; microbe-induced plant resistance (MIR); plant–microbe–insect interactions; sublethal effects; sustainable pest control.
