目的:观察和评价杀它仗在敌鼠钠盐灭效差地区灭鼠控制鼠疫流行的效果。方法:选择通过敌鼠钠盐毒谷饱和投药灭鼠无法降低鼠密度的地区,采用杀它仗回合式投药灭鼠,夜笼法测定灭鼠效果。结果:敌鼠钠盐毒谷灭鼠后第15天考核,灭效35.84%。改用杀它仗毒饵24小时后观察毒饵1176粒,盗食246粒,摄食率20.92%,第10天再次观察600粒,盗食9粒,摄食率1.5%,第11天考核,灭鼠效果100%。结论:敌鼠钠盐灭黄胸鼠的效果,在持续使用18年的地区灭效显著下降,采用杀它仗灭鼠可获得理想的灭效。杀它仗成品毒饵可替代敌鼠钠盐应用于鼠疫疫情的控制工作。
Objective: To observe and evaluate the effect of killing its battle against the epidemic of plague in rodent control areas with poor efficacy of sodium salt. Methods: In the area where rat density could not be reduced by saturated administration of sodium and sodium salt poison valley in rats, rodenticides were used to kill rats and caged animals were assayed by night cage method. Results: On the 15th day after antiemetic treatment, the antagonist sodium salt poison valley was 35.84% off. Use to kill its battle drug bait 24 hours after the observation of bait 1176, stealing food 246, feeding rate of 20.92%, the first 10 days to observe 600 tablets, stealing 9, feeding rate of 1.5%, the first 11 days assessment, anti-rat effect 100%. CONCLUSION: The effect of anti-human rodent sodium on yellow-thorax rat is significantly decreased after 18 years of continuous use, and killing mice by using it can achieve the desired effect. Kill it to fight the finished product bait can be used as an alternative to the antagonist sodium salt plague epidemic control.
