We analysed electroantennogram (EAG) responses of male and female adults of the European grapevine moth (Denis et Schiffermüller) (Lepidoptera: Tortricidae) collected as larvae from grapevine ( L.) and flax-leaved daphne ( L.). The host-plant odorants tested were either -specific [1-octen-3-ol, ()-β-farnesene, ()-4,8-dimethyl-1,3,7-nonatriene], -specific (2-ethyl-hexan-1-ol, benzothiazole, linalool-oxide, ethyl benzanoate), or were shared by both host-plants (linalool, methyl salicylate). Sex pheromone compounds were also tested. The male response to the major pheromone component (7,9-12:Ac) was higher than to any other stimuli, whereas the response to the minor pheromone components (7,9-12:OH and 9-12:Ac) was not different from the response to the plant odorants. The female response to pheromone was lower or not different from that to plant odorants. Methyl salicylate elicited a higher response in females and ()-β-farnesene elicited a higher response than several other plant odorants in both sexes. Non-significant interactions between host-plant odorant and sex indicated an absence of sex specialization for host-plant volatile detection. The lack of a significant interaction between plant volatiles and larval host-plants suggested that there was no specialization for plant-volatile detection between and individuals.
我们分析了从葡萄（L.）和瑞香（L.）上采集的欧洲葡萄蠹蛾（Denis et Schiffermüller）（鳞翅目：卷蛾科）雌雄成虫的触角电位（EAG）反应。所测试的寄主植物气味剂包括特定于一种寄主植物的[1-辛烯-3-醇、（）-β-法尼烯、（）-4,8-二甲基-1,3,7-壬三烯]、特定于另一种寄主植物的（2-乙基己醇、苯并噻唑、氧化芳樟醇、苯甲酸乙酯），或两种寄主植物共有的（芳樟醇、水杨酸甲酯）。还测试了性信息素化合物。雄性对主要性信息素成分（7,9-12:Ac）的反应高于对任何其他刺激的反应，而对次要性信息素成分（7,9-12:OH和9-12:Ac）的反应与对植物气味剂的反应无差异。雌性对性信息素的反应低于或与对植物气味剂的反应无差异。水杨酸甲酯在雌性中引发的反应更高，（）-β-法尼烯在两性中引发的反应均高于其他几种植物气味剂。寄主植物气味剂与性别之间无显著相互作用，表明在寄主植物挥发性物质检测方面不存在性别特异性。植物挥发物与幼虫寄主植物之间缺乏显著相互作用，表明在和个体之间不存在对植物挥发物检测的特异性。
