摘要

Insecticide resistance in Anopheles culicifacies, the major vector of malaria in tribal areas of Chhattisgarh, was determined using standard WHO susceptibility tests. Majority of the districts in Chhattisgarh are highly malaria-prone and under the Enhanced Malaria Control Project (EMCP), where synthetic pyrethroids are used for indoor spraying against An. culicifacies. Resistance/susceptibility of An. culicifacies to DDT (4%), malathion (5%) and deltamethrin (0.05%) was studied in a few villages of Kanker and Jagdalpur, Mahasamund and Raigarh Districts. The corrected mortality varied from 13.8 to 25 % to DDT, 59.3 to 87.9% to malathion and 89.4 to 92.5% to deltamethrin. The tests also revealed a higher knock-down time for An. culicifacies collected from the Kanker and Jagdalpur Districts where synthetic pyrethroid is being sprayed, indicating incipient resistance to synthetic pyrethroid in this vector species.
