Attraction of wireworms to root-emitted volatile organic compounds of barley

Abstract: The ability of wireworms (Agriotes sordidus Illiger) to orientate towards a blend ofvolatiles emitted by chopped roots of barley was tested. During individual tests, the larvae chosebetween the two sides of a Y-shaped olfactometer. One side was connected to a chambercontaining the chopped roots and the other was connected to an empty chamber. Wirewormschose significantly more often the side of the olfactometer providing the blend of root volatiles.This result underlines the importance of the identification of these compounds and their roleassessment alone or combined, as for their effect on wireworms. Such compounds could be usedin IPM strategies.
