中文摘要:

【目的】 烟田一般多种害虫同时发生,为明确烟田蛾类害虫性诱芯之间的相互作用。【方法】 采用性诱芯两两叠加的方法,调查并比较烟田斜纹夜蛾Spodoptera litura、棉铃虫Helicoverpa armigera、烟青虫Helicoverpa assulta和小地老虎 Agrotis ypsilon性诱芯之间的相互作用。【结果】 小地老虎诱芯与烟青虫诱芯复合使用,对小地老虎的诱捕量显著多于小地老虎诱芯单独使用,两者的平均诱捕量分别为(2.83±0.95)头/诱捕器/d和(1.17±0.79)头/诱捕器/d;这种复合诱芯对烟青虫的诱捕量也显著多于烟青虫诱芯单独使用,两者的平均诱捕量分别为(3.00±1.46)头/诱捕器/d和(0.83±0.54)头/诱捕器/d。斜纹夜蛾诱芯单独使用对斜纹夜蛾的诱捕量最多,为(7.83±1.97)头,小地老虎诱芯、棉铃虫诱芯和烟青虫诱芯分别与斜纹夜蛾诱芯复合,对斜纹夜蛾的诱捕量均会显著下降,这3种复合诱芯的诱捕量分别为(2.17±1.08)、(2.67±1.26)和(4.33±1.89)头/诱捕器/d。【结论】 烟青虫性诱芯和小地老虎性诱芯复合的诱集效果对2种靶标均表现显著的增效作用,而斜纹夜蛾性诱芯无论和其他任一种类性诱芯复合使用均表现为拮抗作用。

英文摘要:

[Objectives]  Using sex pheromone lures to trap tobacco pests is both environmentally friendly and effective. However, antagonistic interactions may occur when the sex pheromones of more than one pest are simultaneously deployed. Understanding these interactions will allow such combinations of sex pheromones to be avoided. [Methods]  Interactions between different combinations of sex pheromones used to trap Spodoptera litura, Helicoverpa armigera, Helicoverpa assulta, and Agrotis ypsilon, were investigated in Taipingba town, Fengdu county, Chongqing. [Results]  A combination of A. ypsilon and H. assulta sex pheromones caught significant more A. ypsilon moths[(2.83±0.95) moths/trap/day] than those caught by the A. ypsilon pheromone alone [(1.17±0.79) moths/trap/day]. This pheromone combination also caught significantly more H. assulta [(3.00±1.46) moths/trap/day] than traps baited with H. assulta sex pheromone alone [(0.83±0.54) moths/trap/day]. Spodoptera litura sex pheromone caught more S. litura moths [(7.83±1.97) moths/trap/day] than all other lures tested. However, combining this pheromone with either the A. ypsilon, H. armigera, or H. assulta, sex pheromones significantly decreased the number of S. litura moths captured to (2.17±1.08), (2.67±1.26) and (4.33±1.89) moths/trap/day, respectively. [Conclusion]  A combination of H. assulta and A. ypsilon sex pheromones had a significant synergistic effect, but combining S. litura sex pheromones with those of other species significantly decreased the number of S. litura captured.
