45%苯醚·硫酰氟熏蒸剂现场灭蟑药效试验研究

Field test of the biological efficacy of the 45% mixed fumigant of sulfuryl fluoride with d-Cyphenothrin on cockroach control

目的观察45%苯醚·硫酰氟熏蒸剂现场熏蒸灭蟑效果。方法选择宾馆餐厅的操作间施用45%苯醚·硫酰氟熏蒸剂10～20g/m3,观察72h蜚蠊密度变化。结果 45%苯醚·硫酰氟熏蒸剂现场使用10～20g/m3时,标示性蜚蠊6～72h死亡率为88.04%～100%,处理后72h蜚蠊密度平均下降率为82.46%～98.53%。结论 45%苯醚·硫酰氟熏蒸剂可用于密闭场所灭蟑。

Objective To observe the killing efficacy of the 45% mixed fumigant of sulfuryl fluoride with d-Cyphenothrin on cockroaches. Methods The 45% mixed fumigant of sulfuryl fluoride with d-Cyphenothrin was applied at 10-20 g/m3 in the kitchen operating area of a hotel restaurant and the change in the cockroach density was observed. Results The cockroach mortality rate was 88.04%-100% within 6-72 h after application of the mixed fumigant at 10-20 g/m3, with an average decrease of 82.46%-98.53% in the cockroach density 72 hours after the application of the fumigant. Conclusion The 45% mixed fumigant of sulfuryl fluoride with d-Cyphenothrin can be used to kill cockroaches in confined spaces.
