不同果实诱捕器外观及颜色对实蝇的引诱特性研究

Study on the Attraction Characteristics of Bactrocera tau by the Appearance and Color of Different Fruit Traps

  • 摘要: 通过采用不同颜色和形状的果实模型诱捕器和雄性性诱剂在野外田间对南亚果实蝇进行引诱试验,比较其对南亚果实蝇的引诱效果。同时比较果实模型诱捕器和市售诱捕器对南亚果实蝇的引诱效果,分析其诱杀效果显著水平,选出引诱效果更好的诱捕器。其结果表明:不添加任何性诱剂时与添加液体性诱剂或者添加一片固体性诱剂时,三种果实模型诱捕器的诱捕效果均依次为HG+1Y>SG+1Y>QC+1Y;而在添加两片固体性诱剂时,三种果实模型诱捕器的诱捕效果依次为HG+2Y>QC+2Y>SG+2Y;而在果实模型诱捕器和市售诱捕器使用效果中显示:HG+Y和HZ+Y对南亚果实蝇的诱捕效果最佳,六种诱捕器的诱捕效果依次为HZ+Y>HG+Y>QC+Y>SG+Y>SJ+Y>YG+Y。

     

    Abstract: Using fruit model traps of different colors and shapes and male sex attractants to attract Bactrocera tau in the field, the attraction effects on Bactrocera tau were compared. At the same time, the attraction effects of fruit model traps and commercially traps on Bactrocera tau were compared, and the significant level of their trapping effects was analyzed, in order to select traps with better attracting effects. The results showed that: (1) Compared with adding liquid attractant or a piece of solid attractant without any sex attractant, the trapping effects of the three fruit model traps were in the order of HG+1Y>SG+1Y>QC+1Y; (2) When two pieces of solid attractant were added, the trapping effects of the three fruit model traps were HG+2Y>QC+2Y>SG+2Y; (3) Effect of using fruit model traps and commercial traps: HG+Y and HZ+Y had the best trapping effects on Bactrocera tau. The trapping effects of the six traps were in the order of HZ+Y>HG+Y>QC+Y>SG+Y>SJ+Y>YG+Y.
