摘要: 目的 确定长爪沙鼠对敌鼠钠盐的敏感性.方法 采用高、中、低3个浓度毒饵以急性无选择攻毒的方式对实验室内饲养的长爪沙鼠进行敌鼠钠盐敏感性测试.结果 各浓度的敌鼠钠盐毒饵对长爪沙鼠的致死率均为100%;在测试条件下,高浓度药物试鼠的死亡时间稍短;但低浓度处理雌雄试鼠摄毒总量(0.457、0.394 mg)显著低于中(0.704、0.834 mg)、高浓度(1.614、1.358 mg)处理组.结论 采用低浓度可以降低鼠防成本,并有助于延缓抗药性的产生时间,从而延长敌鼠钠盐使用寿命.

Abstract: Objective To determine the susceptibility of Meriones unguiculatus to sodium diphacinone. Methods Baits containing high, medium, and low concentrations of sodium diphacinone were given to M. unguiculatus raised in the laboratory to test the acute toxicity of this rodenticide. Results The mortality rate was 100% in the M. unguiculatus receiving baits with different concentrations of sodium diphacinone. Although the lethal time was a little shorter in the M. unguiculatus treated with high-concentration bait, the total intake of sodium diphacinone was significantly lower in female and male M. unguiculatus treated with low-concentration bait (0.457 mg and 0.394 mg) than in those treated with medium-concentration bait (0.704 mg and 0.834 mg) and those treated with high-concentration bait (1.614 mg and 1.358 mg). Conclusion Use of the bait with low concentration of sodium diphacinone can reduce the cost of rodent control, and it can delay the development of rodenticide resistance, thus prolonging the service life of sodium diphacinone.
