目的 了解 0 .0 0 5 %溴敌隆普通毒饵和蜡块毒饵对大白鼠的适口性及杀灭效果 ,为使用此类药物灭鼠提供依据。方法 选择性摄食试验和毒杀效果观察。结果 0 .0 0 5 %溴敌隆普通毒饵和蜡块毒饵对大白鼠的摄食系数分别为 0 .81和 0 .6 6 ;毒杀率都达到 10 0 % ;平均死亡时间分别为 5d和 6 .3d ;雌性试鼠对溴敌隆更为敏感 ,雄性试鼠对溴敌隆较为耐受。结论 0 .0 0 5 %溴敌隆普通毒饵和蜡块毒饵对鼠类适口性好 ,毒效高。
Objective To understand the palatability and killing effect of 0.050% bromadiolone bait and wax block bait on rats, and to provide the basis for the use of such drugs in rodent control. Method of selective feeding test and poisoning effect observation. Results The feeding coefficient of 0. 0 0 5% bromadiolone and wax block baits was 0.81 and 0.6 6, respectively. The poisoning kill rates reached 100%, and the average death time was 5d and 6 respectively .3d; Female test rats were more sensitive to bromadiolone, male test rats were more tolerant to bromadiolone. Conclusion 0. 0 0% 5% of bromadiolone common bait and wax block bait for mice palatability, high toxicity.
