Field ‐based Evaluation of a Novel SPME‐GC‐MS Method for Investigation of Below‐ground Interaction between Brassica Roots and Larvae of Cabbage Root Fly, Delia radicum L.

ConclusionThis study shows that volatiles released by broccoli roots can be collected in situ using SPME fibres within perforated PTFE tubes under field conditions. Plants damaged by Delia radicum larvae could be distinguished from plants sampled pre‐infestation and soil controls on the basis of larval feeding‐induced sulphur‐containing volatiles. These results show that this new method is a powerful tool for non‐invasive sampling of root volatiles below‐ground. Copyright © 2016 John Wiley & Sons, Ltd.
