摘要葡萄莓蛾（Endopiza viteana Clemens）雌虫的信息素腺提取物中含有主要信息素成分Z9-12Ac，每只约1.2 ng，同时含有11-14Ac的两种几何异构体，以及一些链长为12-16的饱和乙酸酯和醇。在一些腺体提取物中发现了类似的醇Z9-12OH。在主化合物Z9-12Ac 10 μg的基础上，添加0.5或2 μg的Z11-14Ac可显著提高雄虫捕获率；而添加0.5或2 μg E11-14Ac对其无显著影响。相比之下，在主化合物中加入5%的Z9-12OH导致陷阱捕获的强烈减少。以Z9-12Ac及其几何异构体E9-12Ac为诱饵的诱捕效果明显不如Z9-12Ac和Z11-14Ac为诱饵的诱捕效果。了解信息素成分和拮抗剂是发展交配中断技术的必要条件。在欧洲葡萄中鉴定出的化合物对葡萄的三种最重要的三角害虫都有行为活性。因此，有可能使用一种合成信息素的混合物来控制几种物种。
Abstract Pheromone gland extracts of grape berry moth females, Endopiza viteana Clemens, contain the main pheromone component, Z9–12Ac, at ≈1.2 ng per female, together with both geometric isomers of 11–14Ac, and a number of saturated acetates and alcohols of the chain length 12–16. The analogous alcohol, Z9–12OH, was found in some gland extracts. Trap capture of males was significantly increased by adding 0.5 or 2 μg of Z11–14Ac to 10 μg of the main compound, Z9–12Ac; whereas, adding 0.5 or 2 μg of E11–14Ac had no significant effect. In contrast, the addition of 5% Z9–12OH to the main compound resulted in a strong reduction in trap capture. Traps baited with a blend of Z9–12Ac and its geomeric isomer, E9–12Ac, which was not detected in gland extracts, were significantly less attractive than traps baited with blends of Z9–12Ac and Z11–14Ac. Knowledge of pheromone components and antagonists is essential for development of the mating disruption technique. The compounds identified in E. viteana are behaviorally active in the three most important tortricid pests of grape, Vitis vinifera (L.), in Europe. It may thus be possible to use a single blend of synthetic pheromone for control of several species.
