Interpretive Summary:

Technical Abstract: Some plants respond to herbivory by emitting volatiles that attract natural enemies of the herbivores responsible for the damage. Several herbivore-induced plant volatiles (HIPVs) are known to affect the behavior of pest and beneficial insects. Thus, chemical signaling by plants in response to herbivore attack has potential for enhancing biological control in agroecosystems. To date, however, little is known about practical application of HIPVs for crop protection. In this poster we report on the neurophysiological and behavioral effects of arthropods in response to several HIPVs. Lygus species (a pest) and A. iole (a natural enemy of Lygus) showed differential responses to HIPVs in electroantennography and behavioral bioassays. In a field study, beneficial insects were attracted to HIPVs and parasitism of Lygus eggs was greater in HIPV treatments than in untreated controls. Our results suggest that HIPVs have potential for enhancing biological control in agroecosystems and underscores the need for further research.
