摘要
目的 :探讨灭鼠后家鼠数量恢复情况和规律 ,为制定灭鼠巩固措施提供依据。方法 :采用 0 .0 0 5 %溴敌隆毒米饱和投毒灭鼠 ,后逐月用粉迹法和笼夜法测定鼠密度。结果 :灭鼠较彻底、环境卫生条件好的住宅区 ,低鼠密度可保持 5～ 6个月 ,8个月后鼠密度即恢复到灭鼠前的水平。环境卫生差 ,鼠密度高的农村 ,仅通过毒鼠难以把鼠密度降到较低水平 ;即使通过连续灭鼠把密度大幅度降下来 ,但 1～ 2个月后又恢复至灭鼠前的水平。不同季节灭鼠效果有明显差异。结论 :灭鼠后家鼠数量恢复的速度与灭鼠率、环境卫生条件有关 ,即灭鼠率高、环境卫生条件好的恢复慢 ;否则 ,恢复快。农村灭鼠必须把毒鼠和改造环境结合起来 ,方能有效控制鼠害。
Object: To probe into the rule and inquire into the density restorative situation of domestic rodents population,which would aid for institution of effective measures in rodent's control. Method: Poison bait of 0.005% Bromadiolone was used for killing rats with surplus baiting method, and then the population density was determined with powderedspot and cagetrap captured menthods every months Result: The lower population density of domestic rodnts could be kept for 5-6 months in the areas with better general sanitation and higher rats killing efficiency, and the density didn't restore until 8 months later. While in those areas with poor general sanitation and high population density of domestic rodents,it was very difficult to make down to a lower level just by killing rats with rodenticide only. Even though a large number of rodenticide with continuing bating had it be treated with,it should keep the low level of rodent density not longer than 1 or 2 months. For killing rats there was obvious difference in effiency between different seasons. Conclusion: The density restoration in population of domestic rodents affer killing rats is related to the environment sanitary condition and the killing efficiency. The duration of restoring is relatively longer in the area with high rats killing efficiency in good general sanitary, and shorter with conversely. For successful rodents control in suburbs, the rats killing with rodenticide must be in combination with improving of general sanitary.
