克鼠星1号灭鼠效果研究

目的在实验室内及现场对“克鼠星1号”灭鼠剂的杀灭效果进行试验,为抗凝血灭鼠剂的选择使用提供依据。方法进行实验室“克鼠星1号”对SD大鼠和小白鼠有选择性和无选择性杀灭试验,并进行现场毒杀试验。结果有选择性杀灭试验,SD大鼠和小白鼠对“克鼠星1号”摄食系数分别为0.30和0.38。无选择性杀灭试验,SD大鼠连续3次给药毒杀率可达100%,小白鼠连续2次给药毒杀率90%。现场试验,3 d饱和投毒饵,灭效92.59%。结论“克鼠星1号”灭鼠剂适口性良好,对SD大鼠和小白鼠有较好的杀灭效果,可作为家栖鼠化学防制的有效选择之一。

Efficacy of Keshuxing No.1 against rodents

Objective To observe the efficacy of Keshuxing No.1 against SD rats and mice in both laboratory and field,and provide evidential support for practical selection of anticoagulant rodenticide.Methods Selective and nonselective feeding tests of Keshuxing No.1 against rats and mice were conducted in laboratory.Results The feeding indices of Keshuxing No.1 for SD rats and mice were 0.38 and 0.30 respectively in selective feeding tests.In nonselective feeding tests,the death rates of SD rats and mice were 100% and 90% respectively after 3 consecutive feeding.The killing rates of Keshuxing No.1 against mice and rat in the field tests were 92.86% and 91.67% respectively.Conclusion The palatability of Keshuxing No.1 for rat and mouse is good.It has very good killing effect on mouse and rat in both laboratory and field.Keshuxing No.1 can be an effective choice for chemical prevention and control of house mouse.
