Using to much insecticides for long time can caused resistence of mosquito. This research aim to know resistance status of </em>Aedes aegypti <em>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 </em>15, <em>30, </em>45 <em>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 &lt;80% is resistance, between 80-98% is tolerance and 99-100% is suscepti­ble. </em>Aedes <em>aegyptifrom endemic rural in district Cimahi showed resistance of cypermethrin 0.2% and OA%. This result showed that all mosquito still alive after </em>15 <em>minutes spreading by cypermethrin 0.2%, and only </em>6.7% <em>mosquito death in cypermethrin OA%. After 30 minutes, death mosquito counted </em>46.7% <em>in cypermethrin 0.2% and </em>73.3% <em>in OA%. </em>46.7% <em>mosquito was death in </em>45 <em>and 60 minutes spreading by cypermethrin 0.2% and </em>73.3% <em>in OA%. The result showed resistance ratio (RR50) ofmosquito is </em>4.6. Aedes <em>aegyptifrom en­demic rural in district Cimahi showed a resistance to cypermethrin 0.2% and OA%.</em><strong><em></em></strong></p><p class="Style"><strong><em>Keywords: </em></strong>Aedes aegypti, <em>cypermethrin, resistance, Cimahi district</em></p></td></tr></tbody></table>
