Abstrak: Nyamuk Aedes aegypti adalah nyamuk yang paling sering menyebabkan penyakit Demam Berdarah Dengue (DBD). Berbagai macam upaya telah dilakukan untuk pengendalian nyamuk Aedes aegypti salah satunya dengan cara penyemprotan (fogging) insektisida golongan karbamat. Penggunaan dari insektisida golongan karbamat yang tidak rasional dapat menyebabkan peningkatan enzim asetilkolinesterase sehingga dapat menimbulkan resistensi terhadap nyamuk Aedes aegypti. Tujuan: Mengetahui status resistensi

... rva nyamuk Aedes aegypti terhadap insektisida golongan karbamat di Kecamatan Denai kota Medan. Metode: Penelitian ini merupakan penelitian deskriptif dengan menggunakan metode potong lintang dimana menggunakan 276 larva nyamuk Aedes aegypti. Hasil Penelitian: Hasil penelitian diperoleh larva nyamuk Aedes aegypti yang rentan terhadap insektisida golongan karbamat sebesar 66.3% dan sebesar 33.7% larva nyamuk Aedes aegypti toleran terhadap insektisida golongan karbamat dan larva nyamuk Aedes aegypti yang bersifat resisten tidak dijumpai. Kesimpulan: Sebanyak 33.7% larva nyamuk Aedes aegypti toleran terhadap insektisida golongan karbamat. Abstract: Aedes aegypti is the main vector mosquito that causes Dengue Hemorrhagic Fever (DHF). Various efforts have been made to control the Aedes aegypti mosquito by fogging carbamate insecticides. The use of an irrational carbamate insecticide causes an increase in the acetylcholinesterase enzyme so that caused resistance to the Aedes aegypti larvae. Objective: To determine the resistance status of Aedes aegypti larvae to insecticides of the karbamat group in Kecamatan Medan Denai. Method: This study was a descriptive research design with cross sectional design, which used 276 Aedes aegypti larvae. Results: The results of this study found 66.3% of larvae that were susceptible to carbamate insecticide, 33.7% of larvae were tolerant to carbamate insecticides and resistant larvae were not found. Conclusion: 33.7% of Aedes aegypti larvae are tolerant to carbamate insecticides.
