Phenolic compounds are generally believed to be key components of the oxidative defenses of plants against pathogens and herbivores. However, phenolic oxidation in the gut fluids of insect herbivores has rarely been demonstrated, and some phenolics could act as antioxidants rather than prooxidants. We compared the overall activities of the phenolic(More)
Tannins are believed to function as plant defenses against caterpillars, in part, as a result of their oxidation in the midgut lumen. One putative mode of action that has not been examined in leaf-feeding larvae is oxidative stress in midgut tissues that results from tannin oxidation in the midgut lumen. The test species used in this study, Malacosoma(More)
