摘要
云杉八齿小蠹(Ips typographus L.),是云杉的重要害虫,不仅侵害衰弱木或风倒木,还危害活立木,引起树木流脂,减少结实量,导致针叶大量脱落,最终使林木大片枯死。为了控制该虫的猖獗和危害,开展聚集信息素诱捕云杉八齿小蠹的试验。云杉八齿小蠹聚集信息素弥散载体含有效成份为甲基丁烯醇、顺式马鞭草烯醇、小蠹二烯醇。使用自制塑料水管、塑料薄膜和硬纸板涂胶等多种诱捕器,通过1988—1989两年的试验,证明了选用塑料膜制成的管型诱捕器,制作简易,使用方便,成本低廉,其成本仅为常用的塑料水管的1/10,而且材料易得,运输和携带均方便,适于林区推广使用。
Spruce bark beetle (IPs typographus L.) is the most important pest of spruce. It attackts weaken trees as well as normal ones. It can cause the shedding of resin, the decreasing of seed production and the losing of needles. In the end the tree will die. To control the damage of this pest, the trapping experiment was conducted by using 'Ipslure' and several kinds of traps (including plastic pipes, pipes of plastic film and thick paper stick with glue.) The experiment being conducted from 1988 to 1989 showed that the pipes made of plastic film can be produced and used easily. The cost of this kind of trap is only one tenth of the normal plastic pipes. This kind of trap can be widely used in the mountain area.
