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。
In the winter of 1991 to the spring of 1992, Jiashijia village in the eastern suburbs of Jinan used 0.5% poisonous rat poisoned wheat poison bait to eliminate domestic rats, and the rate of rodent control was 66.06% by the grid powder method. The remaining rats were treated with 0.05% Bait to kill, the results of the three groups of anti-rat corn bait efficiency are very good, 3 weeks after the rodent rate was 93.77%, 94.59% and 100%; and three groups of anti-rat sodium bait efficiency than the Low, rodent rate were 77.27%, 72.04% and 88.36% respectively. Among them, three trials of the naive mouse sodium bait continued to be saturated with the same kind of bait for several times, and the effects disappeared to 72.27%, 20.04% and 94.24% respectively after 5 months of observation. The above results show that using acute rodenticide postemergence sodium bait prepared by the same type of bait also produce antifeedant phenomenon, and more stable.
