各种消灭木材害虫的物理方法实用性差异很大。用 r 射线和热空气加热,可以有效地杀灭木材害虫.X 射线不能有效地杀死木材害虫,但是,用 X 射线可以不破坏木材而检验防虫措施的效果.高频和超高频电磁波以及超声波的作用尚未得到足够的研究,缺少相应的实用设备.冷冻可以杀死木材害虫.真空杀虫没有实际意义.用物理方法杀虫不破坏木材,效果好,不造成环境污染,对古建筑、文物和木竹制品等特别适用.物理方法杀虫没有预防作用,不能完全代替化学方法.
Practicality of various physical methods to eliminate wood pests varies greatly. X-rays do not kill wood pests effectively by heating with r-rays and hot air, but X-rays can be used to check the effectiveness of pest control measures. High frequency and UHF electromagnetic waves and The role of ultrasound has not been enough research, the lack of appropriate practical equipment. Frozen can kill wood pests. Vacuum insecticide is not meaningful. With physical methods insecticide does not destroy the wood, the effect is good, does not cause environmental pollution, ancient buildings, Cultural relics and wood bamboo products, etc. Physical Methods Insecticide has no preventive effect and can not completely replace chemical methods.
