| 摘 要： | 考查斜纹夜蛾Spodoptera litura(Fabricius)性信息素诱捕器放置高度、间隔距离以及气象因子对性信息素诱集效果的影响。结果表明,放置高度为1m时,性信息素诱捕器易引起斜纹夜蛾的反应,明显优于0.5m和1.5m的诱集效果。诱捕器放置的间隔距离,以25m为诱集效果最佳,与10,15,20及30m的具有显著差异。夜间风向对诱捕器的诱蛾效果具有明显影响,在3个成一列放置的诱捕器中,诱集量最大的是放在上风口位置的诱捕器;同时,与夜间风向平行设置的诱捕器,其诱集量显著高于与夜间风向垂直设置诱捕器的诱集量。 |

| Abstract: | The effects of the height of trap, the distance between traps, and the weather factors were determined on the trapping efficiency of the traps to Spodoptera litura （Fabricius）. The results showed obviously higher trapping efficiency at 1 m from the ground than those at 0.5 or 1.5 m. The best distance between traps was 25 m, at which the traps showed higher efficiency than those between 10, 15 or 20 m. There was a significant influence of the wind direction at night on the trapping efficiency. The windward trap attracted more moths than the others. Meanwhile, the traps paralleling with the direction of the wind at night trapped more adults of S. litura than the traps being vertical to the wind direction. |
