斜纹夜蛾与烟青虫或棉铃虫性诱芯同器安放对诱捕效果的影响

Effect of the Same Device Installation of Sexual Inducer for Prodenia litura( Fabricius) with H. assulta( Guenée) or Helicoverpa armigera Hubner on Trapping Efficacy

[目的]明确斜纹夜蛾与烟青虫或棉铃虫性诱芯同器安放对诱捕效果的影响。[方法]比较斜纹夜蛾与烟青虫、斜纹夜蛾与棉铃虫2种性诱芯同器安放较单一安放的诱捕效果差异。[结果]烟青虫、斜纹夜蛾性信息素同器安放和棉铃虫、斜纹夜蛾性信息素同器安放对斜纹夜蛾诱捕效果无任何影响,在烟青虫、斜纹夜蛾或棉铃虫、斜纹夜蛾共同发生的烟区或烟地,可同器安放烟青虫、斜纹夜蛾性信息素或棉铃虫、斜纹夜蛾性信息素;由于烟青虫、棉铃虫虫口基数小,诱捕虫量少,烟青虫、棉铃虫性信息素与斜纹夜蛾性信息素同器安放是否对烟青虫、棉铃虫诱捕效果存在干扰还需进一步开展试验进行验证。[结论]该研究结果为"二合一同器应用"与"二合一性诱芯产品"的开发提供了理论依据。

[Objective]The aim was to clear effect of the same device installation of sexual inducer for Prodenia litura(Fabricius)with H.assulta(Guenée)or Helicoverpa armigera Hubner on trapping efficacy.[Method]We compared the difference in trapping efficacy between the same device installation of sexual inducer for Prodenia litura(Fabricius)with H.assulta(Guenée)or Helicoverpa armigera Hubner and the single device installation.[Result]There was no effect on the trapping efficacy of Prodenia litura(Fabricius)between the same device installation of sexual inducer for Prodenia litura(Fabricius)with H.assulta(Guenée)and Prodenia litura(Fabricius)with Helicoverpa armigera Hubner,so in the co-occurring area of Prodenia litura(Fabricius)and H.assulta(Guenée)or Prodenia litura(Fabricius)and Helicoverpa armigera Hubner,the same device installation of sexual inducer for Prodenia litura(Fabricius)with H.assulta(Guenée)and Prodenia litura(Fabricius)with Helicoverpa armigera Hubner could be used.Due to small population and small trapping quantity of H.assulta(Guenée)and Helicoverpa armigera Hubner,further tests were needed to verify the interference of the same device installation of sexual inducer for Prodenia litura(Fabricius)with H.assulta(Guenée)and Prodenia litura(Fabricius)with Helicoverpa armigera Hubner on the trapping effect of H.assulta(Guenée)and Helicoverpa armigera Hubner.[Conclusion]The result provides reference for the development of installation of the same device and two-in-one of sexual inducer.
