摘　　要：目的研究口岸常用熏蒸剂硫酰氟杀灭蜚蠊卵荚的最佳投药剂量与时间关系。方法在实验室对各组美洲大蠊卵荚进行熏蒸处理,观察其孵化情况,运用趋势面模型分析方法对实验数据进行拟合,并通过现场实验验证。结果趋势面模型有统计学意义(F=26.776,P<0.000 1,判定系数R^2=0.918);该模型可预测硫酰氟熏蒸杀灭卵荚的剂量与时间关系;现场实验按照预测剂量-时间数据,运用熏蒸剂量计算公式计算,起始投药浓度为36 g/m^3、投药量为2.7 kg、熏蒸作用20 h,杀灭率达100%。结论掌握硫酰氟杀灭蜚蠊卵荚的最佳剂量与作用时间关系,为指导口岸有效开展集装箱熏蒸杀虫工作提供依据。Objective To study the fumigant effect of sulfuryl fluoride on Blattaria＇s ootheca and to explore the relationship of the dose and time. Methods We separated the oothecas of Periplaneta americana into different groups in the laboratory. We used sulfuryl fluoride to fumigate them and then observed their hatching situation. All the experimental data were fitted by the trend surface model and verified by field experiment. Results The trend surface model of the ootheca of the P. americana was statistically significant（F=26.776, P〈0.000 1, R^2 = 0.918）. The model effectively predicted the dose and time relationship of the Blattaria＇s oothecas killed by sulfuryl fluoride. The field killing rate of the ootheca was100% based on the initial concentration of 36 g/m^3, the dosage of 2.7 kg and the fumigation time of 20 h which according to the predicted dose-time data and fumigation dose formula. Conclusion According to this study, we calculated the optimal dose-time model of sulfuryl fluoride to kill the Blattaria＇s ootheca. And we can guide the port to carry out fumigation and insecticide work of containers more effectively.
