为了评价溴氰菊酯浸泡蚊帐防制嗜人按蚊及其防疟效果的成本效益。通过对以往资料的分析表明，试验区与对照区比较，试验区嗜人按蚊密度下降８５％～９０％；浸帐后试验区疟疾发病率可减少６４．７％～８９．０％。按人均处理面积核算成本，溴氰菊酯浸泡蚊帐法（浸泡蚊帐１０．１９ｍ２／人）的费用为０．２４４元／人；ＤＤＴ室内滞留喷洒（３０．９７ｍ２／人）的费用为０．７０８元／人；溴氰菊酯室内滞留喷洒（３０．９７ｍ２／人）的费用为１．０２４元／人。三者成本比率为１∶２．９∶４．２。研究结果表明，使用溴氰菊酯浸泡蚊帐防制疟疾媒介，可控制疟疾传播和减少疟疾发病率；并且使用方法简易，群众易掌握；成本比滞留喷洒低，对人畜安全，对蚊帐无腐蚀损坏作用
To evaluate the cost-effectiveness of deltamethrin-impregnated mosquito nets against Anopheles anthracis and its effectiveness against malaria. The analysis of past data shows that the density of Anopheles anthropophagus in the experimental area is reduced by 85% -90% compared with that in the control area. The incidence of malaria in the experimental area after the immersion can be reduced by 64.7% -89.0%. According to the per-processing area accounting cost, the cost of deltamethrin-impregnated nets method (soaking nets 10.19m2 / person) was 0.244 yuan / person; the cost of DDT indoor detention spraying (30.97m2 / person) was 0.708 Yuan / person; deltamethrin indoor residual spraying (30.97m2 / person) costs 1.024 yuan / person. The cost ratio of the three is 1: 2.9: 4.2. The results show that the use of deltamethrin soaked mosquito nets to control malaria vectors can control the spread of malaria and reduce the incidence of malaria; and the method of use is simple, easy to grasp by the masses; the cost is lower than that of stagnant spray; it is safe for humans and animals; effect
