稳定控制鼠疫疫源地黄鼠数量方法研究

Study on the Control Methods for the Quantity of Citellus dauricus Brandt in Plague Epidemic Areas

目的 :有效地控制黄鼠数量增长 ,以长期稳定地控制鼠疫。方法 :踏查鼠密度 ,确定灭鼠地段 ,并实地踏查验收。灭鼠以生态、物理方法为主 ,溴敌隆杀灭为辅。结果 :有鼠面积占 3村总面积的 2 0 %。超标面积为135hm2 ,平均洞密度为 13 .5个 / 10hm2 。灭鼠后洞密度为 0 .6 7个 / 10hm2 ,灭洞率达 95 % ,达到稳控鼠疫标准 (黄鼠密度 <2只 / 10hm2 )。结论 :此方法适合我国国情 ,有很强的可操作性和科学性 ,灭效好 。

Objective: To control Citellus dauricus Brandt effectively and to control the incidence of plague for a long time. Method:The density of rodents was investigated and the areas of eliminating rodents were confirmed.Ecological and physical measures were the main method of eliminating rodents combing with rodenticides. Result:The rodent density befor treating was 13.5 holes per ten hectas.The rodent density after treating was 0.67 holes per ten hectas (the standard:<2 holes per ten hectas). The rodent control rate was 95%. Conclusion: The methods suitable for the China situation can raise the effectiveness and benefits of eliminating rodents.
