研究了重齿小蠹信息素诱捕器设置技术。结果表明,窗式、交叉式和漏斗式诱捕器的诱虫效果不同,窗式诱捕器的诱虫效果最好,交叉式的次之,漏斗式的最差;诱捕器设置的高度对诱捕效果有明显的影响,设置高度为2m的诱捕器诱捕作用最强;不同颜色的诱捕器的诱虫效果不同,黑色诱捕器诱虫效果最好,其余的依次为红色、绿色、白色和黄色的;设置于距林缘不同距离的诱捕器的诱捕作用不同,随着设置距离的增加,诱捕量逐渐减少,距林缘20m的诱捕器诱虫效果最好。
The technique of setting pheromone traps in Bethlehemia nitida was studied. The results showed that the trapping effect of the trapezoidal, cross and funnel traps was different, the trapping effect of the trapping traps was the best, followed by the trapezoidal traps, and the hopper was the worst. The trapping height The traps with different color had different trapping effects, the black traps had the best trapping effect, the rest were red, green, white and yellow in turn; Traps placed at different distances from the forest edge had different trapping effects. With the increase of the set distance, the trapping amount gradually decreased, and the traps at the distance of 20m from the forest edge had the best trapping effect.
