摘　　要：目的:了解0.005%大隆的现场灭鼠效果,为今后应急状况下控制鼠类提供科学依据。方法:选择雷州市雷城镇相邻的地理景观、生态环境等因素基本一致4个自然村居民区作为现场实验区。其中3个为大隆毒饵实验区,另一个为敌鼠钠盐毒谷对照区。采用食饵消耗法,分别计算不同的投药天数食饵的消耗率及其灭鼠效果。结果:在大隆实验A、B、C区的灭鼠率分别为77.5%、89.8%、90.4%,敌鼠钠盐对照D区的灭鼠率为78.8%。结论:大隆一次性投药灭效与敌鼠钠盐连续3次投药灭鼠效果基本一致。大隆连续2次投药灭鼠效果明显大于敌鼠钠盐连续3个投药的灭鼠效果。大隆连续3次投药灭鼠效果可达90%以上。在应急状态下实施灭鼠,可选择大隆。To understand the field deratization effect of 0.005% Brodifacoum poison bait on the rodents, and to improve the scientific basis for control of rodents on emergency situations in the futrue.nethods：Take the four villages who have the same geographical conditions and ecological factors in Leizhou as a field test area.Three of which is test area with Brodlfaeoum poison bait, and the other is comparative area with Diphacine Na-sal poison bait.We calculate different of dosage rates and effects of prey rodent by using prey consumption.Results：Brodifacoum experiment in A, B, C area, anti-rodent rates were 77.5%, 89.8%, 90.4%.Anti-rodent rate was 78.8% in comparative area with Diphacine Na--sal poison bait. Conclusion：The effect of one-time dosage with Brodifacoum as basically the same as the rodent effect of consecutive three times dosage with Diphacine Na-sal poison bait.The effect of row 2 dosage with Brodifacoum is significantly greater than the effect of Diphacine Na-sal＇ s.The effect of one-time dosage with Brodifacoum as basically the same as the rodent effect of consecutive three times dosage with Diphacine Na-sal poison bait.The effect of three-time dosage with Brodifacoum consecutively up to 90%.The implementation of rodent control in emergency state can adopt brodifacoum.
