Abstract:
This work describes the application of a Headspace Solid-Phase
Microextraction method (HS-SPME) to characterize the volatile organic compounds
(VOCs) emitted in vivo by Achillea collina plants infested by the aphid species Myzus
persicae. VOCs induced by mechanical damage simulating the aphid’s damage were
also investigated. Many volatiles appeared as new compounds after infestation as
well as after mechanical damage. In particular, among terpenes we found α-
fenchene, cisβ-terpinol, pinocarvone, aromadendrene, iso-caryophyllene, Dgermacrene
and α-patchoulene. (3Z)-hex-3-enyl acetate was the most abundant
volatile compound isolated in mechanically damaged plants. New insight in plantinsect
interaction may positively reflect on new pest and crop management strategies
in the future.
