用气相色谱(GC)和气相色谱-质谱(GC-MS)分析,证明反-8,反-10-十二碳二烯醇醋酸(B)是大豆食心虫[Leguminivora glycinivorella(Mats.)]性信息素的组分。通过触角电位(EAG)测试,发现反-10-十二碳烯醇醋酸酯(A)、B 和反-7,顺-9-十二碳二烯醇醋酸酯(C)对该虫雄蛾触角有强烈刺激作用。大量田间诱蛾试验表明,由 A 和 B 两化合物组成的性引诱剂,对该虫雄蛾有很高的引诱活性。其中 A 和 B 按5∶2混合,剂量50μg/诱捕盆,单盆每日最多诱捕雄蛾达776头,诱捕雄蛾总数是1头活雌蛾的16.8倍。顺-10-十二碳烯醇醋酸酯(D)和反-10-十四碳烯醇醋酸酯(E)降低 AB 的引诱活性,甘油作为缓释剂,能延长诱芯的有效期,即诱蛾活性。上述结果表明,我国大豆食心虫性信息素不同于日本大豆食心虫性信息素。小面积防治应用试验效果明显。
The anti-8, trans-10-dodecadienyl acetic acid (B) was proved to be Leguminivora glycinivorella (Mats.) Sex information by gas chromatography (GC) and gas chromatography- Vegetarian ingredients. The trans-10-dodecenol acetate (A), B and trans-7, cis-9-dodecadienyl acetate (C) Tentacles have a strong stimulating effect. A large number of field trials of moths showed that the sex attractants composed of A and B compounds had very high attraction activity to the male moth. Among them, A and B were mixed by 5: 2 and the dose was 50μg / trap. The number of males trapped up to 776 in single baskets per day, and the total number of male moth trapping was 16.8 times of that of one live female. Cis-10-dodecenol acetate (D) and trans-10-tetradecenol acetate (E) reduce the AB attractant activity. Glycerol, as a sustained-release agent, can prolong the effective period of the attractant, Moth activity. The above results show that our country soybean pod borer sex pheromone is different from Japanese soybean pod bore sex pheromone. Small area control application test results are obvious.
