Abstract

Volatile organic compounds (VOCs) from alive Anoplophora glabripennis (ALB) imagoes, larvae and ovipositions were obtained by enrichment on adsorbents. They were analysed qualitatively by thermal desorption coupled with gas chromatography and a mass selective detector. All together 229 substances were identified: 34 from larvae, 19 from imago and 176 from oviposition. Ovipositions of two generations were analysed, both over an 8 week period with focus on aging and repeatability. (+)-α-Longipinene occurred in 100%, (+)-Cyclosativene and α-Cubebene in 99% of all oviposition measurements. 1R-α-Pinene occurred in 100% of all imago measurements. 2,4-Dimethyl-1-Heptene and (+)-Cyclosativene were detectable in all three ALB sample types.
