摘要
目的观察0.005%溴敌隆和0.0375%杀鼠迷对Wister大白鼠和Km小白鼠的再遇适口性和灭效,为现场灭鼠药物的选择提供依据。方法将大白鼠和小白鼠分别分为对照组、0.005%溴敌隆组和0.0375%杀鼠迷组,通过有选择摄食试验,观察和比较两种灭鼠药物的再遇摄食系数和毒杀率。结果大白鼠、小白鼠对0.005%溴敌隆的再遇摄食系数分别为1.05和2.89,毒杀率均为100%;大白鼠、小白鼠对0.0375%杀鼠迷的再遇摄食系数分别为0.81和0.32,毒杀率分别为100%和91.67%。结论溴敌隆和杀鼠迷都有较好的再遇适口性和灭效,溴敌隆再遇适口性优于杀鼠迷。
Objective To observe feed- again palatability and killing efficacy for rodent to 0.005% brornadiolone and 0. 0375 % cournatetralyl in laboratory and to provide evidences for practice. Methods Wister mice and KM rats were randomized into 3 groups including the control, the bromadiolone, and the coumateralyl respectively. Carry on food choice- test and observe feed - again palatability and killing efficacy on the basis of the coefficient of the bait intake and the mortality. Results In the brornadiolone group, the coefficients of the bait intake were 1.05 and 2.89 for the mice and rats respectively, and were 0.81 and 0.32 for cournatetralyl. The percentages of the killing efficacy for the mice and rats were both 100% for bromadiolone, and 100% and 91. 67% for coumatetralyl respectively. Conclusions Both 0. 005% brornadiolone and 0. 0375% cournatetralyl have good feed- again palatability and satisfactory rodent killing efficacy, but the brornadiolone is a little better than that of the cournatetralyl. They have similar lethal crest- time at the 6th day and the 7th day.
