目的:了解溴鼠灵对黄胸鼠的毒杀效果.方法:采用常规方法对黄胸鼠进行有选择性试验、无选择性试验和现场灭效观察.结果:有选择性试验,黄胸鼠对0.005%大米、小麦和稻谷毒饵的摄食系数分别为0.52、0.67和0.64.无选择性试验,0.005%大米、小麦和稻谷毒饵1次给药毒杀率分别为70%、80%和40%;3次给药毒杀率分别为100%、100%和90%.现场试验,0.005%小麦毒饵连续3次投药,毒饵盗食率为54.75%,灭鼠率为93.44%.结论:该药适口性好,现场灭效高,可大面积推广应用.“,”Objective: To study the toxicant efficiency of Brodifacoum against R. flavipec-tus. Method: The routine method was taken to observe the palatability and the killing efficiency of Brodifacoum for R. flavipectus. Results: The feeding index of R. flavipectus were 0. 52, 0. 67 and 0. 64 to 0. 005% paddy bait, 0. 005% rice bait and wheat bait in choice test. One-day and three-days nonchoice feeding tests of 0. 005% Brodifacoum bait, the deeth rates of R. flacipectus were 40~80% and 90~100% respectively. The field test of 0. 005% wheat bait was conducted. The feeding rate was 54. 75% and the killing rate was 93. 44%. Conclusion: The Brodifacoum were well palatable and killing efficiency to R. flacipectus. It is the popularization and application in Yunnan.
