【摘要】目的研究和比较几种常用白蚁防治药剂对白蚁的毒力。方法采用毒土穿透试验和药膜法。
结果毒死蜱对散白蚁的穿透域值在8～10mg/kg,吡虫啉需要在20mg/kg以上才能完全阻止白蚁的穿透,
氟虫胺是阻止散白蚁穿透的最有效药剂之一,其穿透域值为1mg/kg;联苯菊酯对散白蚁的穿透域值在018～
1mg/kg,氯菊酯的为5～10mg/kg,氰戊菊酯的为10～20mg/kg。在药膜法试验中,致使白蚁全部死亡的各药
物浓度分别为:吡虫啉100mg/L、氰戊菊酯30mg/L、毒死蜱为8mg/L、氯菊酯均为10mg/L、联苯菊酯为018
mg/L、氟虫胺为013mg/L。结论对非驱避性白蚁防治药剂,白蚁在穿透过程中会发生较高的死亡率,甚至
达到100%,对拟除虫菊酯类的驱避性白蚁防治药剂,白蚁在穿透过程中发生的死亡率较低,并且穿透的药物
浓度与死亡率不呈正相关线性关系。氟虫胺和联苯菊酯对白蚁的毒力最高,其次为毒死蜱、氯菊酯和氰戊菊
酯,吡虫啉的毒力最低。
