Status Resistensi Aedes aegypti (Linn.) terhadap Organofosfat di Tiga Kotamadya DKI Jakarta

High cases of Dengue Fever in Jakarta increased efforts to control the population of Aedes aegypti by using insecticides. Insecticides which are often used in that control are malathion and temefos which derived from the class of organophospat. Associated with resistance in many areas, the purpose of this article is to know the susceptibility of Ae. aegypti in endemic areas in Jakarta to insecticide malathion and temefos. This study was an observational study with cross sectional design. Research sites in nine Puskesmas in East Jakarta, West Jakarta and South Jakarta. The study population was all the houses located in highest endemic area in nine regions of Puskesmas. Sample survey in the form of 100 homes / buildings in each area. Larvae survey conducted in the home / building, then the larvae obtained were collected for later colonization to 3rd generation. Susceptibility test to 0.8% malathion is done by using impregnated paper refers to the WHO method, whereas susceptibility test to temefos test was conducted by elliot. Result of this research shows that in all research areas have been resistant to organophosphate insecticides (Temefos and Malathion 0.8%). The use in the long term is suspected to be the cause of resistance to the insecticide malathion Ae.aegypti 0.8% and temefos 0,02ppm.
