| 摘 要： | 研究了下列害虫和寄生天敌种类对大豆植株中提取的某些挥发性次生化合物及其不同组合混合相的触角电位反应： 1)豆蚜Aphis craccivora Koch和麦长管蚜Macrosiphum avenae (Fabricius)；2)为害大豆植株的大豆蚜Aphis glycines Matsumura和不为害大豆植株的豆蚜二者所共有的寄生天敌豆柄瘤蚜茧蜂Lysiphlebus fabarum Marshall; 3)不为害大豆植株的麦长管蚜的寄生天敌燕麦蚜茧蜂Aphidius picipes Nees。结果表明，与大豆植株相关联的大豆蚜和不相关联的豆蚜所共有的天敌——豆柄瘤蚜茧蜂，对大豆植株的挥发性次生化合物及其混合相反应敏感，而与大豆植株不相关联的豆蚜、麦长管蚜及其寄生天敌——燕麦蚜茧蜂，对大豆植株的挥发性次生化合物及其混合相反应不敏感。再次证明，植物挥发性次生化合物在害虫及其寄生天敌搜寻寄主的过程中起到重要的作用。

| Abstract: | Electroantennogram (EAG) responses to several chemical volatiles of soybean plant were investigated for the following four species of insects: 1) Aphis craccivora Koch and Macrosiphum avenae (Fabricius); 2) Lysiphlebus fabarum Marshall, the common nature enemy of Aphis glycines Matsumura which is the pest insect of soybean plant, and of A.craccivora which is not the pest insect of soybean plant; 3) Aphidius picipes Nees, the nature enemy of M.avenae which is not the pest insect of soybean plant. The results showed that L.fabarum related indirectly with soybean plant in nature was sensitive to the tested volatiles and their mixtures; the rest three species of insects irrelative to soybean plants in nature were not sensitive to the volatiles and their mixtures. This suggested the important function of plant volatiles in host searching of natural enemies of the phytophagous. |
