Abstract: Objective:By comparing palatabilites and death rates of five acute rodenticides and mixtures of it and picricid,laboratory basis was provided for using of picricid.Methods:Adopting tests of the choice feeding and the no choice feeding with mice.Results:The feeding indexes of Zinc phosphide,Silatranes,Gophacide,Desmethylbromethalin and Bromethalin were respectively 0.57,only eating a few grains,0.03,0.93,2.1;After adding picricid,the feeding indexes were separately 1.5,only eating a few grains,0.38,0.93and 5.2.The death rates were separately 100%,90%,100%,100% and 100%;After adding picricid the death rates all were 100%.Conclusion:It has satisfactory killing effect against mice that picricid and the five acute rodenticides are mixtured.

摘要： 目的:通过比较苦味剂与5种急性灭鼠剂合用的适口性及灭鼠效果,为苦味剂的应用提供依据。方法:采用有选择及无选择摄食试验。结果:5种急性灭鼠剂磷化锌、毒鼠硅、毒鼠磷、敌溴灵、溴杀灵的摄食系数分别为0.57、只吃几粒、0.03、0.93、2.1,加入苦味剂后的摄食系数分别为1.5、只吃几粒、0.38、0.93、5.2;有选择试验杀灭率为100%、90%、100%、100%、100%;无选择试验加入苦味剂后均为100%。结论:苦味剂与5种急性灭鼠剂合用有很好的灭鼠效果。
