小菜蛾雄蛾对不同组分、比例和剂量的人工合成引诱剂的田间反应(英文)

Field behavioral responses of male diamondback moth,Plutella xylostella to different components,ratios and dosages of synthetic sex attractant in China

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.

Trapping experiments were set up in Chinese cabbage field to test the potential for improving lures for pheromone traps of diamondback moth,Plutella xylostella in China.The field test showed that catch was improved by adding 0.01% of（Z）-9-tetradecenyl acetate to lures that are currently used in China.Traps were significantly more attractive to the male adults in the field baited with ternary blends of（Z）-11-hexadecenal,（Z）-11-hexadecenyl acetate and（Z）-11-hexadecenol in 7∶3∶1 ratio than those baited in other ratios of ternary blends.Lures captured more males when loaded with four-component mixtures of（Z）-11-hexadecenal,（Z）-11-hexadecenyl acetate,（Z）-11-hexadecenol and（Z）-9-tetradecenyl acetate in a ratio of 70∶30∶10∶0.01 at the dose of 10 μg than at other doses,which are recommended for the use in male trapping in China.
