Analisis Daya Resistensi Nyamuk Aedes aegypti Terhadap Insektisida Malathion di Wilayah Fogging Kabupaten Malang Bagian Selatan Sebagai Sumber Belajar Biologi

DHF is an acute febrile disease through the bite a mosquito that infected with the dengue virus through the vectors of Aedes aegypti and Aedes albopictus which are found almost all corners in Indonesia. Dengue Hemorrhagic Fever can attack all age groups. Dengue fever often causes extraordinary events in several region in Indonesia. Malang Regency Government used chemical control, namely fogging with the insecticide Malathion to break the chain of transmission of DHF caused by the Aedes aegypti mosquito. Fogging is an eradication effort by fumigating to kill adult mosquitoes. Insecticides that are often used for fogging are organophosphate ester insecticides such as sumithion, phenithrothion, cypermethrin and malathion. Continuous use of insecticides can cause resistance to target insects. The study aims to describe the resistance of Aedes aegypti mosquitoes into malathion insecticide 0.8% in 3 fogging areas of southern Malang Regency, and analyze differences the resistance of Aedes aegypti mosquitoes originating from 3 fogging areas in southern Malang Regency. The study was carried out starting from preparing materials to be used, landing collection of Aedes aegypti mosquito eggs and larvae, rearing eggs and larvae to becoming adult mosquitoes, identifying Aedes aegypti mosquitoes, to conducting a susceptibility test using impregnated paper malathion 0.8%. The susceptibility test treatment used 4 tubes which were divided into 2 groups, they are 1 control tube and 3 treatment test tubes. Type of study is descriptive observational with the sampling technique using simple random sampling. The results of the susceptibility test shows that the mortality rate of the test mosquitoes in the Districts of Kepanjen, Gondanglegi, and Bantur reached 98%, 93%, and 96%, respectively, The three sub-districts have an average percentage of 96% which, when adjusted for the resistance criteria from the WHO in 2016, is tolerant. This shows that the Aedes aegypti mosquitoes in the three locations are classified as tolerant to the insecticide malathion by 0.8%
