The Resistance of Aedes Aegypti to Permethrin 0.25% Insecticide, Malathion 0.8%, and Transfluthrin 25% in the Universitas Islam Bandung Tamansari Campus

Abstract

Massive and long term insecticide use causes resistance of mosquitos to insecticides. This research has a goal for assessing the resistance of Aedes aegypti to the insecticides of permethrin 0.25%, malathion 0.8%, and transfluthrin 25% in the Universitas Islam Bandung Tamansari campus. The Aedes aegypti resistance in the Universitas Islam Bandung Tamansari campus Bandung city to insecticides measured with the susceptibility test in September 2015. The susceptibility test to the permethrin 0.25% and malathion 0.8% insecticides implemented by using WHO standard instruments and methods. The susceptibility test to transfluthrin 25% implemented by using commercial insecticide according to the usage suggestion. The total mosquitos that died after the exposure of permethrin 0.25%, transfluthrin 25%, and malathion 0.8% for 60 minutes were 20%, 23%, and 80%. The WHO criteria state that mosquitos were still susceptible to insecticides if the death rate is 98–100%, tolerant if the death rate is 80–97%, and mosquitos are resistant if the death rate is less than 80%. In conclusion, the Aedes aegypti mosquitos in the Universitas Islam Bandung Tamansari campus are already resistant to the insecticides permethrin 0.25% and transfluthrin 25% and tolerant to malathion 0.8%.
