采用摄食试验方法，选用溴敌隆、杀鼠迷和敌鼠钠盐三种抗凝血灭鼠剂对褐家鼠进行实验室毒效比较。结果无选择摄食试验，溴敌隆、杀鼠迷和敌鼠钠盐三组的毒杀率均为１００％（１４／１４、１４／１４和１１／１１）。有选择摄食试验，溴敌隆组的毒杀率为９２．８６％（１３／１４），摄食系数是０．７０，毒饵接受性好，毒杀率高；杀鼠迷和敌鼠钠盐组毒杀率分别是６１．５４％（８／１３）、３８．４６％（５／１３），其摄食系数分别是０．４５、０．２２。
Using feeding test method, the choice of bromadiolone, war rats and natriuresis three kinds of anticoagulant rodenticides Rattus norvegicus laboratory toxicological comparison. Results There was 100% (14/14, 14/14, and 11/11) of the poisoning kill rates in the three groups with no food choice test, bromadiolone, warfarin and natriuretic sodium. In selective feeding test, the poisoning rate of brooderone was 92.86% (13/14), the food intake coefficient was 0.70, the poison bait had good acceptance and the rate of poisoning was high; Respectively, 61.54% (8/13) and 38.46% (5/13) respectively. The food intake coefficients were 0.45 and 0.22 respectively.
