【摘要】 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更多还原

【Abstract】 The effect of deratization and the drop if rat density were evaluated with the methods of one time baiting in major habitats within the scope of deratization on baiting in minor habitats,only a survey made on rat density before and after deratization,determination of rat density with the night trapping method.The results showed that the effects of deratization with Brodifacoum,Bromadiolone and Zinc phosphide were 100%,100% and 96.83% respectively to the major habitas.The rat density dropped by 87.95% and 97.24% respectively in minor and whole habitats after baiting only in major habitats.This method could save 70% rodenticide and 80% labour,compared with the traditional universal baiting method.We believe that this method,which is reliable,convenient and economical,can effectively control the rat density in hilly areas,and is of great significance in the effective control of epidemics of Epidemic Hemorrhagic Fever(EHF) and of great academic value and value of spread and application.更多还原
