The purpose of this study was to determine the type of insecticides which Aedes aegypti mosquitoes are resistant to, so that other susceptible insecticides still can be used.The study was a cross sectional epidemiological study with Garden cluster sampling in Sub-district Wongsorejo, Banyuwangi, Muncar, Tegaldlimo, Kalibaru which is considered sufficient to represent Banyuwangi Regency.Mosquito samples appropriate to the characteristics were isolated and tested for insecticide-resistance primer namely voltage gated sodium channel (VGSC) to determine the specific resistance expressed in mosquitoes.The result of resistance test using WHO standard method showed that Aedes aegypti mosquito from Banyuwangi Regency were resistant to cypermethrin 0.25% and malathion 0.

8%.There was a VGSC coding gene with 250 bp band Intimates Set detected using polymerase chain reaction (PCR) technique which was associated with the resistance of Aedes aegypti mosquitoes in Banyuwangi Regency to organophosphate insecticides (malathione) and pyrethroid insecticides (cypermethrin).
