地震后临时居住地蝇类防治效果观察

Efficacy of flies control in temporary habitation

目的采用溴氰菊酯控制蝇类密度,预防地震后肠道传染病的暴发流行。方法使用了空间喷雾与滞留喷洒相结合的实验组与对照组的对比实验。结果采用0.05%溴氰菊酯每天喷洒厕所、垃圾集中点、生活污水排放处,持续6 d,对照组与实验组经统计学处理(P<0.05),均有显著差异;人住帐篷和厨房内滞留喷洒溴氰菊酯,帐篷内药效可持续7 d,厨房内仅持续4 d,对照组与实验组经统计学处理(P<0.05),有显著性差异。结论溴氰菊酯空间喷雾和滞留喷洒均能有效降低蝇类密度。

Objective To control flies density with deltamethrin and prevent intestinal infectious disease after earthquake. Methods Using residual spraying and space spraying. Results Toilet, rubbish heaps and waste water ditches were sprayed with 0. 05% dcltamethrin for 6 days, apparent differences existed between test group and control group among three spots （ P 〈 0. 05 ）. The tents were sprayed by residual spraying, the efficacy could last for 7 days. Kitchens were sprayed by residual spraying, the efficacy could last for 4 days. Apparent differences existed between test group and control group （ P 〈 0. 05 ）. Conclusion Space spraying and residual spraying of deltamethrin can reduce the flies densities efficiently.
