摘　　要：目的观察温度和相对湿度对硫酰氟熏蒸灭鼠效果的影响。方法试验在模拟熏蒸箱内进行,均匀设计实验方案,通过单因素和多因素分析判断温度、湿度和剂量对硫酰氟熏蒸灭鼠效果的影响。结果单因素分析显示硫酰氟剂量和温度影响灭鼠效果,剂量从0.750g/m3增至0.892g/m3,鼠死亡率从30%升至70%;不同湿度(25%～85%)鼠死亡率差异无统计学意义;均匀设计多因素分析显示相对湿度、剂量与小鼠的死亡率有关,以小鼠的死亡率为应变量,温度、相对湿度和剂量为自变量,进行二次型回归分析,得回归方程:P=-0.00839H+1.03677D。结论硫酰氟熏蒸灭鼠效果好,在实际工作中,应根据湿度和温度变化科学调整熏蒸时的投药剂量。Objective To determine the impact of temperature and relative humidity on sulturyl tluonde tumlgatlon against rats. Methods The study was conducted in a simulated fumigation container in order to determine the impact of temperature, humidity and sulfuryl fluoride doses on the fumigation against rats. Results Univariate analysis showed that sulfuryl fluoride efficacy was affected by dose and temperature. As the dose increased from 0.750 g/m3 to 0.892 g/m3, the mortality of rat increased from 30% to 70%. There was no significant difference in the mortality among different humidity groups （25%-85%）. Multivariate analysis revealed that relative humidity and dose were correlated with the mortality. The quadratic regression equation with the mortality rate of mice as the dependent variable, and temperature and humidity as the other variables was： P=-0.008 39H＋1.036 77D. Conclusion The fumigation dosage of sulfuryl fluoride should be adjusted based on humidity and temperature.
