本文以3种不同浓度的敌鼠钠盐毒谷对残存鼠及非残存鼠作了耐药性观察.结果表明残存鼠对敌鼠钠盐具有明显的抗药性,但依然有效,在经常广泛投放敌鼠钠盐灭鼠药的内环境,只要适当增加其浓度,仍可收到较好的毒杀效果. In this paper, three kinds of different concentrations of the enemy rat poisoning sodium sodium poisoning on the residual and non-residual mice made resistance showed that the remaining mice on the antagonist sodium salt has obvious resistance, but still effective, often widely used in the release of the enemy sodium salt rodenticide Environment, as long as the appropriate increase in its concentration, can still receive a good poison kill effect.
