Abstract

The incidence of dengue hemorrhagic fever (DHF) has increased significantly throughout the world in the last decade. One of the challenges in eradicating DHF is the occurrence of vector resistance to insecticides. This study aimed to looked at the mutation site of the VGSC codon F1534C Aedes aegypti on RT 5 & 6 Pancur Pungah Village, Muara Dua District, Ogan Komering Ulu Selatan Regency as a marker of resistance. The samples in this studied were larvae and pupae of Aedes aegypti. Larvae and pupae were bred into F1 generation and then tested for susceptibility and followed by polymerase chain reaction (PCR). The results of the suscepbillity test carried out obtained mosquito mortality of 10.5% so it was categorized resistant based on WHO criteria. Continued PCR test found no mutation point occurred in the VGSC gene mutation point F1534C in Aedes aegypti. Therefore, the possibility of mutations in the VGSC gene is at another mutation point. Keyword: Mutation, Aedes aegypti, F1534C   ABSTRAK Kejadian demam berdarah dengue (DBD) telah meningkat signifikan di seluruh dunia dalam dekade terakhir. Salah satu tantangan dalam pemberantasan DBD adalah kejadian resistensi vektor terhadap insektisida. Penelitian ini bertujuan untuk melihat titi mutasi gen VGSC kodon F1534C Aedes aegypti di RT 5 & 6 Kelurahan Pancur Pungah Kecamatan Muara Dua Kabupaten Ogan Komering Ulu Selatan sebagai penanda terjadinya resistensi. Sampel pada penelitian ini adalah larva serta pupa nyamuk Aedes aegypti. Larva dan pupa dibiakkan menjadi generasi F1 lalu dilakukan uji suscepbillity dan dilanjutkan uji polymerase chain reaction (PCR).  Hasil penelitian pada uji  suscepbillity yang dilakukan didapat kematian nyamuk sebesar 10,5% sehingga dikategorikan resisten berdasarkan kriteria WHO. Dilanjutkan uji PCR didapat tidak terjadi titik mutasi pada gen VGSC mutasi titik F1534C pada Aedes aegypti. Oleh karena itu, kemungkinan terjadinya mutasi pada gen VGSC berada pada titik mutasi yang lain. Kata kunci: Mutasi, Aedes aegypti, F1534C
