槐小卷蛾性诱剂的合成与林间诱蛾活性试验

槐小巷蛾（ＣｙｄｉａｔｒａｄｉａｓＭｅｙｒｉｋ）性诱剂的主要成分为（反、反）－８，１０－十二碳双烯－１－醇（简式ＥＳＥ１０－１２：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，ＥＳＥ１０－１２：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。

SYNTHESIS AND FIELD EXPERIMENTS OF SEX ATTRACTANT FOR CHINESE LOCUST MOTH,CYDIA TRASIAS MEYRICK(LEPIDOPTERA:TORTRICIDAE)

The sex attractant for Chinese locust moth(Cydia trasias Meyrick),(E,E )-8,10-dodecadien-1-ol,was synthesized via Crignard coupling reaction from two readily available starting materials containing C8 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-baitedtrap 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.
