Grapevine moth Lobesia botrana is the economically most important insect of grapevine Vitis vinifera in Europe. Flower buds, flowers, and green berries of Chardonnay grapevine are known to attract L. botrana for oviposition. The volatile compounds collected from these phenological stages were studied by gas chromatography-mass spectrometry, and the antennal response of L. botrana females to these headspace collections was recorded by gas chromatography-electroantennography. The compounds found in all phenological stages, which consistently elicited a strong antennal response, were pentadecane, nonanal, and alpha-farnesene. In a wind tunnel, gravid L. botrana females flew upwind to green grapes, as well as to headspace collections from these berries released by a piezoelectric sprayer release device. However, no females landed at the source of headspace volatiles, possibly due to inappropriate concentrations or biased ratios of compounds in the headspace extracts.
葡萄小卷蛾（Lobesia botrana）是欧洲葡萄（Vitis vinifera）经济上最重要的害虫。已知霞多丽葡萄的花芽、花朵和绿色浆果会吸引葡萄小卷蛾产卵。采用气相色谱 - 质谱联用技术研究了这些物候阶段收集的挥发性化合物，并通过气相色谱 - 触角电位技术记录了葡萄小卷蛾雌虫对这些顶空提取物的触角反应。在所有物候阶段均发现的、始终引发强烈触角反应的化合物为十五烷、壬醛和α-法尼烯。在风洞中，怀有身孕的葡萄小卷蛾雌虫会逆风飞向绿色葡萄以及由压电喷雾器释放装置释放的这些浆果的顶空提取物。然而，没有雌虫降落在顶空挥发物的来源处，这可能是由于顶空提取物中化合物的浓度不合适或比例有偏差。
