摘要:

槐小卷蛾(Cydia tradias Meyrik)性诱剂的主要成分为(反、反)-8, 10-十二碳双烯-1-醇(简式E8El0-12:OH)。从两个易得的C6原料出发,通过Grignard偶联反应合成了这种性诱剂。林间诱蛾试验结果表明, E8E10-12:OH对槐小卷蛾具有强烈的引诱作用,诱蛾量的变化能及时而准确地反映林间槐小卷蛾的发生与消长情况,从而为进行适时而有效的防治提供科学依据。

Abstract:

The sex attractant for Chinese locust moth (Cydia trasias Meyrick), (E, E)-8, 10-dodecadien-1-ol, was synthesized via Grignard coupling reaction from two readily available starting materials containing C6 units(scheme 1). Field trials were undertaken in Chinese locust grove in Beijing during 1993-1994. The experiments showed that (E, E)-8.10-dodecadien-1-ol gave. strong attractive activity to the male Chinese locust moths. The attractant-baited trap can be used to detect both the presence and the density of the moth in the field, which is very useful for monitoring population of the pest insect.
