摘要:

利用气相色谱和触角电位初步确定沙棘木蠹蛾性信息素的主要组分为顺-7-十四碳烯醇(Z7-14∶OH)、顺-7-十四碳烯基乙酸酯(Z7-14∶Ac)和反-7-十四碳烯基乙酸酯(E7-14∶Ac)。应用本实验室人工合成的标准化合物在不同地点进行2年的田间试验,结果表明:以Z7-14∶Ac、E3-14∶Ac和E7-14∶Ac3种化合物按10∶10∶1配成含量为500μg·个-1的诱芯,其诱蛾效果最好,诱蛾量能准确反映林间沙棘木蠹蛾发生与消长的情况。

Abstract:

We identified the mostly component(Z)-7-tetradecenyl-1-ol(Z7-14∶OH)、(Z)-7-tetradecenyl acetate(Z7-14∶Ac)and(E)-7-tetradecenyl acetate(E7-14∶ Ac)of sex pheromones of Holcocerus hippoophaecolus by gas chromatography(GC)and electroantennographic(EAG)analyses,and trapping trial of male moths with synthetic sex attractant in our laboratory was made.Two years field trial showed that the biological activities of mixture of(Z)-7-tetradecenyl acetate(Z7-14∶Ac)、(E)-3-tetradecenyl acetate(E3-14∶Ac)and(E)-7-tetradecenyl acetate(E7-14∶ Ac)in a 10∶10∶1 ratio are the strongest,and the lure with the mixer had accurate reflection of H.hippophaecolus presence and density.
