摘要: 目的观察杀飞克对印鼠客蚤的实验室毒效和现场灭效。方法实验室用瓶膜法,现场用滞留喷洒法。结果(1)当药物浓度为6.25mg/L时,KT50为5.75min;当药物浓度为12.5、25、50、100mg/L时,KT50分别为3.52、6.07、3.13和3.05min;(2)当药物浓度在12.5mg/L以上时,24h死亡率均为100%;(3)药膜在室温和普通湿度下存放1年后,当药物浓度在50mg/L以上时,24h死亡率均为100%;(4)现场灭效:药物浓度300mg/L对地面游离印鼠客蚤的2d校正灭蚤率为100%,15d校正灭蚤率为82.72%,30d校正灭蚤率为91.24%。结论杀飞克10%可湿性粉剂毒力强,现场灭效好,气味小,对人畜安全,可在控制家鼠鼠疫灭蚤中使用。

Abstract: Objective To study the efficacy of 10% Solfac against Xenopsylla cheopis.Methods In laboratory test residual smearing method was used while in field tests resort spraying method was used.Results(1) When the concentrations of Solfac were 6.25,12.5,25,50 and 100 mg/L,the KT50 values were 5.75,3.52,6.07,3.13,3.05 min respectively;(2) All the insects were killed at the concentrations of Solfac 12.5 mg/L and above;(3) When the insecticide was applied at or more than 50 mg/L using residual smearing,at room temperature and natural humidity,its efficacy could last for more than one year;(4) In field tests,the mortalities of 300 mg/L Solfac to Xenopsylla cheopis was 100% for 2d and 82.72% for 15d and 91.24% for 30d.Conclusion The Solfac can be used in flea control in plague epidemic area.
