Abstract: Objective To explore the measures of economic and effectual control of malaria.Methods Three areas were chosen on similar natural condition、morbidity of malaria and population for the study.The disease reservoir was controlled in each area.The bed nets were treated with 2.5% deltamethrin( 15 mg/m²) in one area.In addition to impregnated bed nets residual spraying with 5% Alphacypermethrin(25 mg/m²) was carried out in cattle、pig pen and people activity areas in another area;No mosquito control measures were adopted in the control area.The study was evaluated and compared with the results of aetiology and the entomology.Results The densities of A.anthropophagus in houses、outside houses(men bait) and cattle、pig pen reduced by 100%,71.96%,94.01%,67.42% respectively,in the area with both treatments of impregnated-bed nets and residual spraying;In the area treated with impregnated bed nets method the densities outside houses(men bait) rose with 12.38% and those in other places was reduced by 99.63% 、18.71%、69.44% respectively.The biting rates ofAn.anthropophagus in the areas of treatment and in the control area were 0.1111,0.2222,1.1688 respectively;The morbidity of malaria in impregnated-bed nets?residual spraying with impregnated-bed nets and control areas decreased by 73.12%,57.71%,65.71% respectively.Conclusion Only impregnated bed nets and impregnated bed nets with residual spraying could reduce the density of A.anthropophagus in the house and they reduced more quickly for the density of A.anthropophagus with impregnated bed nets and residual spraying than for the only impregnated bed nets.
