重齿小蠹信息素诱捕器设置技术的研究

STUDY ON TECHNIQUE OF SETTING UP TRAPS WITH AGGREGATION PHEROMONE OF THE DOUBLE-SPINED SPRUCE BARK ENGRAVER,Lps duplicatus(SAHLB.)

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。

Experiments were carried out from 2007 to 2008 in Baiyinaobao Natural Preserve,Inner Mongolia to study Technique of Setting up Traps with Aggregation Pheromone of the double-spined spruce bark engraver,Ips duplicatus（Sahlb.）.Results show the effect of the catch of window trap is the best among three types.The height of the traps set up affects the effect of the catch of the traps,the height 2m of the traps is the first.The different colors,traps have different effects of the catch,black traps can catch the most bark beetles.Traps set up 20m away from the forest edge have the best effect of the catch.
