对砍伐后存放了不同时间的杨树虫害木分别剖成厚度为１．０ｃｍ、１．５ｃｍ、２．０ｃｍ及２．５ｃｍ的木板，系统调查了木材内光肩星天牛幼虫及蛹的存活情况。试验结果表明伐倒木存放７个月以上时，杨树虫害木内无任何天牛活虫态存在，可安全地制作不同厚度的木包装，并杜绝人为传播；新伐杨树虫害木当剖成厚度为１．５ｃｍ以下的木板时，可全部杀死各虫态的天牛；锯成２．０ｃｍ厚的木板时，所有天牛虫道均已被破坏，天牛虫体暴露在外，严重破坏了生存环境，在剖板后不久即可自然死亡。 Poplar pests stored at different times after harvesting were cut into wood panels with thickness of 1.0cm, 1.5cm, 2.0cm and 2.5cm respectively. The survival of larvae and pupae in the wood was investigated systematically. The test results showed that when the planted wood was stored for more than 7 months, there was no living beetle in the poplar pest wood, which could safely produce wooden packages of different thicknesses and prevent the artificial propagation. When 1.5 cm below the wood, can kill all the horned beetles; sawing into 2.0cm thick plank, all the beetles have been destroyed, beetle body exposed, severely damaged Survival environment, natural death shortly after the profile.
