Daftar Isi:
- Malathion merupakan salah satu jenis insektisida yang telah lama digunakan dalam pemberantasan vektor Demam Berdarah Dengue (DBD) yaitu Aedes aegypti (Ae.aegypti) Pemakaian insektisida dalam jangka waktu lama dapat menimbulkan efek samping seperti resistensi. Tujuan penelitian adalah untuk mengetahui status resistensi A.aegypti terhadap malathion 0,8% di Kelurahan Labuh Baru Timur. Penelitian ini merupakan penelitian observasional deskriptif dengan desain cross-sectional. Larva Ae.aegypti diambil dari 4 RW di Kelurahan Labuh Baru Timur, kemudian dibawa ke laboratorium Parasitologi Fakultas Kedokteran Universitas Riau untuk dipelihara menjadi nyamuk dewasa. Metode uji resistensi yang digunakan adalah metode susceptibility test WHO dengan impregnated paper malathion 0,8%. Nyamuk dipindahkan tabung paparan yang sudah diberi malathion 0,8% dan tabung kontrol masing-masing sebanyak 25 ekor kemudian diamati selama 1 jam untuk melihat nyamuk knockdown. Selanjutnya nyamuk Ae.aegypti dipindahkan ke holding tube, diletakkan pada ruangan selama 24 jam kemudian dihitung mortalitas nyamuk. Hasil penelitian ini menunjukkan mortalitas nyamuk Ae.aegypti 24 jam setelah paparn malathion 0,8% adalah 10%. Pemakaian insektisida dalam jangka waktu lama tidak efektif untuk mengeliminasi vektor demam berdarah karena dapat menimbulkan resistensi. Status resistensi nyamuk A.aegypti di Kelurahan Labuh Baru Timur terhadap malathion 0,8% adalah resisten. Perlu adanya rotasi pemakaian malathion dalam pengendalian Ae.aegyptisebagai vektor DBD. Kata kunci : malathion, resistensi, susceptibility test WHO
- Malathion is a type of insecticide that has long been used in the eradication of Aedes aegypti (Ae.aegypti) as main vector of the Dengue Hemorrhagic Fever (DHF). The use of insecticides in the long term can cause side effects such as resistance. This study aims to determine the resistance status of A.aegypti of malathion 0.8% in Labuh Baru Timur Village. This was a descriptive observational study design, based on its timeused cross-sectional study design. Larvae were taken from 4 RWs in Labuh Baru Timur, then taken to the Parasitology Laboratory of the Faculty of Medicine, Riau University to be reared as adult mosquitoes. The WHO susceptibility test method with 0.8% impregnated paper malathion was used as resistance test method. Twenty five of Ae. Aegypti were transferred to exposure tubes which had been given malathion 0m8% and control tubes then observed for 1 hour to see the knockdown Ae. Aegypti. Furthermore, the Ae.aegypti mosquito was transferred to a holding tube, placed in the room for 24 hours then calculated of Ae.aegypti mortality. This result showed that Aedes aegypti mortality in 24 hours after exposure of malathion 0,8% was 10%. The use of insecticides in the long term is not effective to eliminating dengue vector because it can cause resistance. The resistance status of Ae.aegypti of malathion 0,8% in Labuh Baru Timur Village was resistant. It is necessary to rotate the use of malathion to control Ae.aegypti as a vector of DHF.
