Abstract
Cruciferous plants (Brassicaceae) are characterized by the accumulation of a group of secondary metabolites known as glucosinolates that, following attack by pathogens or herbivores, may be hydrolyzed to one of a number of products including isothiocyanates and nitriles. Despite the range of hydrolysis products that may be produced, the toxicity of glucosinolates to pathogens and herbivores may be explained largely by the production of isothiocyanates. Isothiocyanates are also known to provide an indirect defense by acting as host finding cues for parasitoids of insect herbivores that attack crucifers. It has been speculated that nitriles may provide a similar indirect defense. Here, we investigate the olfactory perception and orientation behavior of the aphid parasitoid Diaeretiella rapae, to a range of alkenylglucosinolate hydrolysis products, including isothiocyanates, nitriles, and epithionitriles.
