松树虫害木存放及剖板处理防止松墨天牛传播

Prevention of Monochamus alternatus from spread by means of piling and thinning beetle infested pinelogs

将砍伐后以不同方式存放的松树虫害木分别剖成厚度为 1 .0 cm、1 .5 cm、2 .0 cm及 2 .5 cm的木板 ,系统地调查木材内部松墨天牛各虫态的存活情况。并由此提出使用松树虫害木做木包装时的各种处理措施。试验结果表明松树虫害木伐倒后在林外存放 1 2个月时 ,松原木内已无任何虫态活天牛 ;而在林内存放时 ,因受到松墨天牛的再侵染 ,还有活虫态存在。新伐的松树虫害木当剖成厚度为 2 .0 cm以下的木板时 ,可杀死绝大多数松墨天牛 ,而且所有天牛虫道均已被破坏 ,虫体暴露在外 。

After being piled in different ways,beetle infested pine logs (BPL) are thinned into boards at different thickness ( 1 0 cm, 1 5 cm, 2 0 cm and 2 5 cm respectively).The situation of Monochamus alternatus inside the logs is systematically examined and quarantine methods are put forward on solid wood packing materials(SWPM)made of BPL.It is concluded that there are no living beetles in BPL after being piled naturally for 12 months outside forest while there are still some in BPL piled inside forest because of the second infestation of the beetles.As to newly felled BPL,different stages of the beetles are almost killed when logs are thinned into boards with thickness of less than 2.0cm,and all galleries of M. alternatus are seriously destroyed,their bodies are exposed to air and they will die naturally soon.
