“…Glucose oxidase (GOX) for instance is found in saliva of different caterpillar species (1). GOX induces defenses in tomato (92) but suppresses them in tobacco and Nicotiana attenuata (30,114). By oxidizing glucose, GOX produces the signaling molecule hydrogen peroxide (H2O2).…”

Diverse molecular processes regulate the interactions between plants and insect herbivores. Here, we review genes and proteins that are involved in plant–herbivore interactions and discuss how their discovery has structured the current standard model of plant–herbivore interactions. Plants perceive damage-associated and, possibly, herbivore-associated molecular patterns via receptors that activate early signaling components such as Ca2+, reactive oxygen species, and MAP kinases. Specific defense reprogramming proceeds via signaling networks that include phytohormones, secondary metabolites, and transcription factors. Local and systemic regulation of toxins, defense proteins, physical barriers, and tolerance traits protect plants against herbivores. Herbivores counteract plant defenses through biochemical defense deactivation, effector-mediated suppression of defense signaling, and chemically controlled behavioral changes. The molecular basis of plant–herbivore interactions is now well established for model systems. Expanding molecular approaches to unexplored dimensions of plant–insect interactions should be a future priority.

“…European Corn Borer Frass Sustains Herbivore-Induced Defenses while Suppressing Pathogen-Induced Defenses in Maize -European Corn Borer herbivory is known to induce defenses in crops such as maize and tomato (Houseman et al 1992;Louis et al 2013a). Oral secretions and saliva of ECB have been implicated in harboring elicitors (and/or effectors) that trigger direct and indirect herbivore defenses in plants (Louis et al 2013a, b).…”

The muga silkworm, Antheraea assamensis Helfer bears great economic importance, producing golden yellow muga silk which is in global demand for both the textile and biomedical industries. The insect's larval stages are maintained in the field by farmers on its primary host plant Persea bombycina Kost in Assam located in the North‐East part (25.57 ° N, 93.25 ° E) of India. If continuous feeding by A. assamensis is inducing any direct defense in P. bombycina, the aspect is not yet questioned. We used the activity of lipoxygenases (LOX) and trypsin inhibitors as markers for determining defense responses in P. bombycina and Litsea monopetala Roxb, the two primary host plants of the silkworm due to insect feeding. The induction of anti‐herbivore trypsin inhibitor by insect feeding was examined by studying their effect on the midgut trypsin activity of A. assamensis larvae. This is the first report showing that the LOX‐ trypsin inhibitor axis is differentially activated in the two host plants and greater induction of the defense response is exhibited in P. bombycina, the most commercially used host plant in muga silkworm rearing.
