Determination of the Three Main Components of the Grapevine Moth Pest Pheromone in Grape-Related Samples by Headspace-Gas Chromatography- Mass Spectrometry
The grapevine moth (Lobesia botrana) is the most significant pest of viticulture.
This article reports the development of an analytical method that allows the instrumental
determination of the three main pheromone components of the pest ((E,Z)-7,9-dodecadien-1-yl acetate,
(E,Z)-7,9-dodecadien-1-ol and (Z)-9-dodecen-1-yl acetate) in grape-related samples (must, table grape
and wine grape). The combination of headspace, gas chromatography and mass spectrometry
provides limits of detection in the range of 60–420 ng/Kg and precision, expressed as a relative
standard deviation, better than 8.5%. This analytical approach is rapid and simple and opens a door
to the study of the pest incidence on the final products
