黄斑卷蛾性诱剂的合成与田间诱蛾活性试验

黄斑卷蛾（Acleris fimbriana Meyrick)性诱剂的主要成分为（反）－11，13－十四碳双烯醛（简式E11，13－14：Ald)。从易得的原料出发，通过Wittig反应合成了这种性诱剂及其类似物。田间诱蛾试验结果表明，E11，13－14：Ald对黄斑卷蛾具有强烈的引诱作用，最佳剂量为1．0mg。单一的（反）－11，13－十四碳双烯－1－基醋酸酯对黄斑卷蛾没有引诱作用，但对E11，13－14：Ald的诱蛾活性有明显的增效作用。而（反）－11，13－十四碳双烯－1－醇和（反）－11－十四碳烯－1－醇，（反）－11－十四碳烯醛对E11，13－14：Ald的诱蛾活性有抑制作用。

SYNTHESIS AND FIELD TRAP TESTS OF SEX ATTRACTANT FOR YELLOW TORTRIX ACLERIS FIMBRIANA MEYRICK(LEPIDOPTERA:TORTRICIDAE)

The sex attractant for yellow tortrix, Acleris fimbriana Meyrick,(E) 11,13 tetradecadienal(E11,13-14:Ald),was synthesized via Wittig reaction from two readily available starting materials. Field trials were undertaken in Beijing during May October, 2000. The tests showed that E11,13 14:Ald gave strong attractive activity to the male yellow tortrix . The optimum dose of E11,13 14:Ald to catch male yellow tortrix was 1.0mg. Single E11,13-14:Ac was not attractive to the male moths, but it could highly enhance the attractive effect when it was added to E11,13 14:Ald. On the other hand, E11,13-14:OH, E11 14:OH and E11 14:Ald inhibited the attractive effect when they were added to E11,13 14:Ald respectively.
