6种常用灭鼠剂对黄胸鼠药效测试

Efficacy Tests for six Staple Rodenticides against Rattus Flavipectus

目的测试6种武汉常见市售灭鼠剂对黄胸鼠药效。方法在实验室做无选择摄食实验,测试6种灭鼠剂对黄胸鼠的药效。结果3号灭鼠剂毒杀率最高为80%,其次为5号和6号毒杀率为70%;4号灭鼠剂毒杀率为60%,1号和2号灭鼠剂毒杀率最低,为10%(表2)。1号和2号与4号鼠药对黄胸鼠的杀灭率有显著差异(P<0.05),与3号、5号和6号鼠药有极显著差异(P<0.01)。结论在以黄胸鼠为主的地点灭鼠可以选用3、4、5、6号灭鼠剂或增加灭鼠剂在现场存留时间。

Objective To study the effect of six staple mdenticides in Wuhan against Rattus flevipectus. Method Test the effents of six kinds of rodentlcides on flevipectus by No - choice feeding experiment in laboratory. Results The death rate of No. 3 rodenticides to Rattus flevipectus was 80%. 5 and 6 rodenticides were 70%. 4 rodenticides were 60%. and No. 1 and 2 rodenticides were 10%. The death rates of No. 1, 2 rodenticides to Rattus flevipectus and No. 4 have obvious difference （P 〈 0. 05 ）, and No. 3, 5, 6 have obvious difference （P 〈 0. 01 ） . Conclusions No. 3 - 6 rodenticide can be selected or keep rodenticides for longer time in rodent control when infested mainly with Rattus flevipectus.
