Emission of volatile organic compounds after herbivory from Trifolium pratense (L.) under laboratory and field conditions.

ABSTRACT: Plants emit a wide range of volatile organic compounds in response to damage by herbivores, and many of the compounds have been shown to attract the natural enemies of insect herbivores or serve for inter- and intra-plant communication. Most studies have focused on volatile emission in the laboratory while little is known about emission patterns in the field. We studied the emission of volatiles by Trifolium pratense (red clover) under both laboratory and field conditions. The emission of 24 compounds was quantified in the laboratory, of which eight showed increased emission rates after herbivory by Spodoptera littoralis caterpillars, including (E)-beta-ocimene, the most abundant compound, (Z)-beta-ocimene, linalool, (E)-beta-caryophyllene, (E,E)-alpha-farnesene, 4,8-dimethyl-1,3,7-nonatri
