云杉八齿小蠹聚集信息素应用技术研究

Research on the application technology of aggregation pheromone of Ips typographus L.

为有效控制云杉八齿小蠹的危害,在长白县十三道沟林场开展了信息素应用技术研究,结果表明:信息诱捕器的有效引诱距离可以达到200 m以上,以林缘外25 m的诱集效果最好;在供试的三种诱捕器中,以漏斗式诱捕器的诱集效果最佳。

To effective control the damage of 1ps typographus L. , research on the application technology of aggregation pheromone was carried out at Shisandaogou forest farm in Changbai county. The results showed that the effective trapping distance of the pheromone traps could be up to 200 m. And the pheromone traps 25 m outside the stand edge got the most catches. As to the three types of traps tested, the funnel trap was the best one in terms of number of the be- etlescaught.
