Identification of the sex pheromone of a protected species, the Spanish moon moth Graellsia isabellae.

abstract：:Oxidative responses of plants to pathogens and other environmental stresses have received considerable recent attention. We propose that an oxidative response also occurs following attack by herbivores. Our data strongly indicate a shift in the oxidative status of soybean following herbivory by the insectHelicoverpa z...
