水浸处理原木杀虫效果的研究

Study on the effect of pest killing by soaking logs in water.

对水浸处理原木杀灭木材中的松褐天牛、横坑切梢小蠹、材小蠹及病害松材线虫的效果进行了研究。结果表明天牛成虫、蛹及小蠹虫较易死亡 ,而天牛幼虫和松材线虫抗逆性强 ,需长时间浸泡。结论认为水浸处理原木需 1年时间或在高温季节处理

Studies on the effect of killing Monochamus alternatus Hope,Blastophagus minor Hartig,Xyleborus sp.,Bursaphelenchus xylophilus Nickle by soaking logs in water were performed.The result indicates that the bark beetles,adult and pupae of longhorned beetles can be killed easily by this method.But larvae of longhorned beetles and nematode need much more time because of their excellent enduring capability.Thus,to reach the purpose of quarantine treatment,the logs should be soaked in water for almost one year or at least 3 months when in summer.
