摘要:

  【摘要】 目的 观察不同杀虫剂的灭蚤效果,筛选优质高效的灭蚤剂。方法 实验室用瓶膜法,现场采用滞留喷洒法。结果 (1)10%功百害悬浮剂和8%大功达可湿性粉剂的药物浓度在0.0025%、0.005%时,印鼠客蚤24 h死亡率均为100%。(2)家仆杀虫剂仅需0.5~3 min就可将旱獭寄生蚤全部击倒,功百害和大功达次之,需5~7 min, 而杜邦万灵所需时间最长,为10~20 min;从死亡时间看,施用家仆杀虫剂5 min内蚤全部死亡,功百害和大功达则需30~40 min,而杜邦万灵所用时间最长,为1~1.5 h。结论 8%大功达可湿性粉剂和10%功百害悬浮剂毒力强,现场灭效好,气味小,经济安全,可在鼠疫疫区现场灭蚤中推广使用。

Abstract:

  【Abstract】 Objective To observe the toxicity of different insecticides to fleas and to screen out new and high effective insecticides. Methods The residual spraying was used in the field, and the bottle film method in the laboratory. Results The mortality rate of Xenopsylla cheopis was 100% after 24 h treatment with the concentration of 0.0025% for 10% Gongbaihai SC and 0.005% for 8% Dagongda WP. Jiapu insecticides could knock down the fleas within 0.5-3 min, followed by Gongbaihai and Dagongda within 5-7 min. The knocking time of Wanling produced by Dupont was the longest with the value of 10-20 min.  For death time, the fleas were all dead within 5 min after treatment, 30-40 min for Gongbaihai and Dagongda, and 1-1.5 h for Wanling of Dupont. Conclusion Dagongda and Gongbaihai can be used for the control of fleas in plague foci.
