为了提高小菜蛾性诱剂的田间诱捕效果,在大白菜地进行不同人工合成引诱剂对小菜蛾的诱捕试验.试验结果表明,增加0.01%的顺-9-十四碳烯乙酸酯能够提高目前诱芯的诱蛾效果.三元组分,顺-11-十六碳烯醛、顺-11-十六碳烯乙酸酯和顺-11-十六碳烯醇在7∶3∶1比例下的诱蛾能力显著优于其它三元组分比例的诱蛾力.比例为70∶30∶10∶0.01的四元组分,顺-11-十六碳烯醛、顺-11-十六碳烯乙酸酯、顺-11-十六碳烯醇和顺-9-十四碳烯乙酸酯,诱芯含量为10μg时在田间的诱蛾效果最好,因而建议在中国使用这种诱芯诱捕小菜蛾.
In order to improve the trapping effect of the sex-inducing agent of Plutella xylostella in the field, Chinese cabbage trapping experiments with different synthetic attractants on Plutella xylostella were carried out.The results showed that 0.01% cis-9-tetradeceneacetic acid ester could increase The current induced decoy effect of the trident, cis-11-hexadecenal, cis-11-hexadecene acetate and cis-11-hexadecenol in a 7: 3: 1 ratio Under the attraction of moths significantly superior to the other three component ratio of the moth force ratio of 70:30:10:0.01 of the quaternary component of cis -11-hexadecenal, cis -11-XVI Cetyl acetate, cis-11-hexadecenol and cis-9-tetradeceneacetate. When the entrapment amount is 10 μg, the effect of entrapping in the field is best, so it is suggested to use this kind of lure in China Core Trapping Plutella xylostella
