当选择用于任何方面的某种有效的杀虫剂时,我们必须考虑它的毒杀目标昆虫的作用方式和影响它的功能的那些特性。在施用木材蛀虫药液的情况下,杀虫剂的功能有如下四个方面:(1)扩展到木材内部的药液,随着溶剂的渗入和杀虫剂大量的游离出来,在药液使用之后,幼虫就立即开始被杀死。(使用的溶剂一般对昆虫幼虫具有毒性)。(2)在溶剂蒸发之后,残余的杀虫剂阻止还活着的幼虫成功地蛀入处理区。(3)由于残余的杀虫剂直接的毒杀作用,或者排斥的作用,阻止成虫成功的羽化,致使蛀虫停留在蛹室,不能通过已处理的木材表层。
When choosing an effective pesticide for any use, we must consider what it does to kill the target insect and how it affects its function. In the case of the wood borer solution, the function of the insecticide has the following four aspects: (1) The chemical solution that extends into the interior of the wood is dissolved in the solution as the solvent permeates and a large amount of insecticide escapes, After that, the larvae begin to be killed immediately. (Solvents used are generally toxic to insect larvae.) (2) Residual insecticide prevents the surviving larvae from successfully eating into the treatment zone after solvent evaporation. (3) As a result of the direct poisoning effect of residual insecticides or their repellent effect, the successful emergence of adult worms is prevented, causing the moth to stay in the pupal chamber and not to pass through the treated wood surface.
