克鼠星1号灭鼠效果研究

Efficacy of Keshuxing No.1 against rodents

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。

Objective To observe the efficacy of Keshuxing No. I 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.
