Abstract

S: Vector control of dengue usually doing by using insecticides, whether by govern­ment or insecticides used in household. Using to much insecticides for long time can caused resistence of mosquito. This research aim to know resistance status of Aedes aegypti from endemic rural in district Cimahi to cypermethrin (synthetic pyretroid). Resistance status knowing by susceptibility methods (WHO standard) with using impregnated paper that con­taining cypermethrin 0.2% and OA%. Aedes aegypti spread by it for 15, 30, 45 and 60 minutes. Number of mortality count by percentage death mosquito in each time and each concentration of cypermethrin. Data interpreted by WHO standard, which percentage of death mosquito <80% is resistance, between 80-98% is tolerance and 99-100% is suscepti­ble. Aedes aegyptifrom endemic rural in district Cimahi showed resistance of cypermethrin 0.2% and OA%. This result showed that all mosquito still alive after 15 minutes spreading by cypermethrin 0.2%, and only 6.7% mosquito death in cypermethrin OA%. After 30 minutes, death mosquito counted 46.7% in cypermethrin 0.2% and 73.3% in OA%. 46.7% mosquito was death in 45 and 60 minutes spreading by cypermethrin 0.2% and 73.3% in OA%. The result showed resistance ratio (RR50) ofmosquito is 4.6. Aedes aegyptifrom en­demic rural in district Cimahi showed a resistance to cypermethrin 0.2% and OA%.
