采用在灭鼠的范围内只对重点生境一次性投毒灭鼠 ,非重点生境不投毒 ,只作投毒前后鼠密度调查。用夹夜法进行鼠密度测定 ,评价灭鼠效果及鼠密度下降情况。结果显示 ,大隆、溴敌隆、磷化锌对重点生境的灭鼠效果分别为 10 0 %、10 0 %及 96 83%。只对重点生境投毒灭鼠后 ,非重点生境及全生境的鼠密度分别下降 87 95 %及 97 2 4%。此种方法比传统普遍投毒灭鼠节省 70 %的药物及 80 %的人工。作者认为 :本方法能有效的控制低山丘陵区鼠密度 ,效果可靠、方便、经济 ,对于有效的控制流行性出血热的流行具有重要意义及极高的学术价值和推广应用价值
Used in the area of rodent control only key habitats once poisoning rodent control, non-key habitats are not poisonous, only for the investigation of rat density before and after poisoning. The rat density method was used to determine the anti-rat effect and the decrease of the rat density. The results showed that the killing effect of Dalong, bromadiolone and zinc phosphide on key habitats was 100%, 100% and 96 83% respectively. After deratting only the key habitats, the rat densities decreased by 87 95% and 97 2 4% respectively in non-key and entire habitats. This method saves 70% of the drug and 80% of the labor compared with the traditional poisoning. The author believes that this method can effectively control the rat density in the hilly area, the effect is reliable, convenient and economical, which is of great significance for the effective control of the epidemic of epidemic hemorrhagic fever and has very high academic value and popularization and application value
