摘　　要：研究了性信息素诱捕器的颜色、形状、粘胶面积以及在树冠内放置的位置对槐小卷蛾Cydiatrasias(Meyrick)雄蛾诱捕效果的影响。结果表明 ,白、绿和黄 3种颜色的诱捕器的诱捕效果明显优于蓝颜色的诱捕效果 ;三角形诱捕器诱捕雄蛾的效果明显优于双层圆盘形和双层船形的诱捕效果 ;粘胶面积为 5 0 0 .0cm2 的三角形诱捕器的诱捕效果明显优于 2 5 0 .0cm2 和 16 6 .7cm2 的诱捕效果 ;悬挂于树冠中上部的诱捕器的诱捕效果明显优于悬挂于树冠中部及中下部的诱捕效果。在槐小卷蛾性信息素监测与防治系统中 ,悬挂在树冠中上部、粘胶面积为 5 0 0 .0cm2The effects of the color, shape, sticky surface area and height in the crown of the sex pheromone traps on capture of Cydia trasias (Meyrick) male moth were evaluated in Zhongguancun, Beijing, in 1999. The white, green and yellow traps were much more effective than blue one. Triangle traps were much more effective than double disc and boat shape traps. The triangle trap of 500.0cm 2 were much more effective than those of 250.0cm 2 and 166.7 cm 2 . The triangle traps hung in upper-middle part of the crown were much more effective than those of in middle and lower-middle parts. Thus, white, triangle traps of 500.0cm 2 provided a reliable tool for monitoring and control in pheromone system of Cydia trasias, when hung in the upper-middle part of the crown.
