摘要
1991年冬至1992年春,在济南东郊宿家村先用0.5%毒鼠磷小麦毒饵灭家鼠,格粉板法测定灭鼠率为66.06%;对残存鼠分别用0.05%敌鼠钠玉米与小麦毒饵进行杀灭,结果三组敌鼠钠玉米毒饵的灭效均很好,3周后灭鼠率分别为93.77%、94.59%和100%;而三组敌鼠钠小麦毒饵的灭效均较低,灭鼠率分别为77.27%、72.04%和88.36%。其中敌鼠钠小麦毒饵三个试验纽继续多次饱和投放同种毒饵,观察至5个月后.灭效分别变为72.27%、20.04%和94.24%。上述结果表明,用急性灭鼠药后家鼠对同种诱饵配制的敌鼠钠毒饵也产生拒食现象,且较稳固。
From the winter of 1991 to the spring of 1992, we controlled rodentsy 0.5% Gophacide wheat bait in Xujia village in east suburb of Jinan. The rate of controlling is 66.96% measured by squared powdere clappers, then, we controlled the remnants by corn and wheat baits Diphacinone-Na. The effects of three groups of corn bait were all good, the rates of controlling after three weeks were separatelly 93.77%. 94.59%, and 100%. Bit the effects of three groups of wheat bait were all bad, their rates were separatelly 77.27%, 72.04%, and 88.36%. Later, we put same bait Diphacinone-Na fully to remnants of the three groups of Wheat bait many times again. Afterwards, we had been observing for five months, the rates of contrclling were separetelly 72.27%, 20.04%and 94.24%. In all, it is said that the remnants refuse same bait Diphaeinone-Na after controlled by acute poisoning, and also the effect is fairly stand
