摘要
虫螨腈在<300 mg/kg浓度时对白蚁没有驱避性,其对白蚁的毒性由本身的施用浓度决定。外界环境(如pH值、有机碳含量、土壤粘性等)也会影响虫螨腈对白蚁的毒性。此外,白蚁的品种、品级也会影响其对虫螨腈的耐受性。高浓度的虫螨腈在土壤中的降解半衰期会比较长,但在模拟施工条件下关于虫螨腈持效期的研究目前还不多见。虫螨腈可以通过复配或其他方式来达到很高的增效目的。虫螨腈会在一些白蚁群体中进行横向传递。建议利用虫螨腈驱避性小、复配有增效及在白蚁群体中可横向传递的特性来制作白蚁饵剂系统控制白蚁危害。
Chlorfenapyr has no repellent effect on termites at a concentration lower than 300 mg/kg. The toxicity of chlorfenapyr to termites is determined by the concentration. The external environmental factors （such as pH value, organic carbon content, and soil stickiness） also affect the toxicity of chlorfenapyr to termites. In addition, termites＇ tolerance to chlorfenapyr is affected by species and grades. Chlorfenapyr has a relatively long degradation half-life at high concentration. However, studies concerning the effective duration of chlorfenapyr under a simulated construction condition are rarely seen. The effectiveness of chlorfenapyr can be synergized by a combined formula or other methods. Horizontal transfer of chlorfenapyr can be found in some termite populations. The characteristics such as low repellent effectiveness, combination synergism, and horizontal transfer in termites can be used in making the bait system for control of termites.
