本文叙述合成性诱剂对粘虫Mythimna separata Walker雄蛾的引诱活性。在北京第二代粘虫发生期间的试验表明,顺—11—十六烯醛对粘虫雄蛾有很强的引诱活性。在顺—11—十六烯醛中加入少量顺—11—十六烯醇乙酸酯(1—10％),能显著地提高诱蛾活性。同时表明在日本活性很高的粘虫诱芯(顺—11—十六烯醇乙酸酯及顺—11—十六烯醇比例为8:1或9:1)在中国北方诱到的粘虫雄蛾数量极少。在中国北方第三代粘虫发生期,以顺—11—十六烯醛和顺—11—十六烯醇乙酸酯(9:1或9.5:0.5)为组分的诱芯对粘虫雄蛾也显示了较弱的引诱活性。
This article describes the lure activity of synthetic attractants against Mythimna separata Walker male. Experiments during the second generation of armyworm in Beijing showed that cis-11-hexadecenal had a strong attractant activity against male armyworm. Adding a small amount of cis-11-hexadecenal acetate (1-10%) to cis-11-hexadecenal can significantly increase the entrapment activity. At the same time, it is shown that the highly active viscera of Japanese armyworms (8: 1 or 9: 1 cis-11-hexadecenol acetate and cis-11-hexadecenol) attracted to northern China Moths are few in number. In the third generation of armyworm in northern China, the entomophores were characterized by cis -11-hexadecenal and cis -11-hexadecenol acetate (9: 1 or 9.5: 0.5) Moths also showed weaker attractant activity.
