<![CDATA[Abstract The study on mosquito diversity was conducted in Jagaraga Village, Buana Pemaca Subdistrict and Sukajaya Village, Buay Rawan Subdistrict of Ogan Komering Ulu Selatan Regency in 2017. This study aimed to analyze population density of mosquitoes, feeding habits and resting behavior of mosquito, and identify the types of potential /specific breeding habitat of mosquito larvae in OKU Selatan regency. Mosquitoes were collected during the night for 12 hours, started at 06.00 p.m. until 06.00 a.m. by human landing, resting, and cattle landing collection methods. The indoor density of mosquitoes ranged from 0.04-3.96 mosquitoes/person/hour with the highest density of 10,7 on Cx.tritaeniorhyncus. Species of mosquitoes collected in Sukajaya Village were more diverse than in Buana Pemaca Village. There were 12 species and the most dominant species was Cx. tritaeniorhyncus (68.09%), Breeding habitats were identified in rice fields, bricks pit, puddle marsh, and flow of rice fields. Abstrak Penelitian tentang keragaman nyamuk telah dilakukan Di Desa Jagaraga Kecamatan Buana Pemaca dan Desa Sukajaya Kecamatan Buay Rawan Kabupaten OKU Selatan pada tahun 2017. Penelitian ini bertujuan untuk mengetahui angka kepadatan populasi nyamuk yang tertangkap, menganalisis kebiasaan mencari makan danperilaku beristirahat masing-masing spesies nyamuk yang tertangkap serta mengetahui jenis-jenis habitat perkembangbiakan potensial bagi larva nyamuk yang ada di Kabupaten OKU Selatan. Penangkapan nyamuk dilakukan selama 12 jam dimulai dari pukul 18.00 WIB malam hingga pukul 06.00 pagi, menggunakan metode human landing collection, resting collection dan penangkapan di sekitar kandang ternak. Spesies nyamuk yang tertangkap 12 spesies dan yang paling dominan yaitu Culex tritaeniorhyncus(68,9%). Kepadatan nyamuk yang menggigit per orang per jam (MHD) di dalam rumah berkisar antara 0,04-3,96 ekor/orang/jam. Kepadatan rata-rata paling tinggi pada nyamuk Cx. tritaeniorhyncus 10,7 ekor. Habitat perkembangbiakan berupa sawah, lubang galian tanah liat untuk batu bata, kobakan, aliran sawah.]]>
