Insect defenses against phototoxic plant chemicals

Abstract:
In addition to avoidance strategies, insects may use one or more biochemical defenses against phototoxic plant constituents or the reactive forms of oxygen they generate. These biochemical defenses may include metabolism; excited state quenching; deactivation of singlet oxygen, superoxide, or free radicals; and destruction of reaction products. This article is a survey of the antioxidative enzymes and simpler molecules produced by insects and their possible roles in combating phototoxic chemicals.
