Impact of residual spraying of Reldan against Anopheles culicifacies in selected villages of District Ghaziabad (Uttar Pradesh), India
Background & objectives : Indoor residual spraying of Reldan 40% EC @ 0.5 and 1g/m2 was done inTatarpur and Chauna villages, respectively in Dhaulana PHC, Distt. Ghaziabad (U.P.) to evaluate itsimpact against Anopheles culicifacies and malaria incidence. Results were compared with that ofPiyawal...

| description | Background & objectives : Indoor residual spraying of Reldan 40% EC @ 0.5 and 1g/m2 was done inTatarpur and Chauna villages, respectively in Dhaulana PHC, Distt. Ghaziabad (U.P.) to evaluate itsimpact against Anopheles culicifacies and malaria incidence. Results were compared with that ofPiyawali village which was taken as control area.Methods : Four rounds of spray were done from 1999–2000 in human dwellings and cattlesheds inexperimental villages. Entomological parameters — man hour density, parity rate, sporozoite rate, etc.were monitored using standard procedures. Epidemiological indicators such as SPR, SFR, cases/000,Pf/000 were also calculated. Cone bioassays as per WHO method were also carried out to assess thepersistence of the insecticide on different surfaces.Results : Entomological results revealed that spraying of reldan @ 0.5 g/m2 resulted in significantreduction in adult densities of An. culicifacies in sprayed villages over the control village. Sprayingalso resulted in reduction of percent parous females, reduction in malaria incidence (p < 0.05).Interpretation & conclusion : Reldan showed high efficacy @ 0.5 g/m2 in controlling the densities ofAn. culicifacies and malaria incidence. However, double dosage of reldan @ 1 g/m2 can be used forcomprehensive vector control provided > 95% spray coverage is achieved. |
