The impact of spraying DDT and HCH on A. culicifacies resistant to DDT and HCH was assessed in Loni PHC, Ghaziabad, U.P. [India]. Monitoring of entomological and parasitological indices revealed that correct insecticidal dosage application and increasing the insecticidal coverage brought about significant reduction in vector densities and the incidence of malaria. The study also showed that there was no advantage of enhancing HCH dosage from 200 to 500 mg/m2 and that DDT performed better in this area.
