Lymphatic filariasis is still become the health problem in Indonesia, the disease almost found inthe entire area with fairly high level endemicity. Karya Makmur Village, Madang Suku III District, EastOgan Komering Ulu Regency, South Sumatera Province in 2007 has micofilariae rate of 1,05% based fromblood survey. The aims of the research is to identify vector and the breeding habitat. This research has beenconducted in Karya Makmur Village from May to November 2011. This type of research is noninterventionstudy with spot survey research design. Mosquitoes collection using human landing andresting collection methods, while mosquito larvae were collected from breeding sites. This research found14 species of Mansonia and Anopheles were collected and the species were Mansonia uniformis, Ma.annulata, Ma. Indiana, Ma. dives, Ma. bonneae, Ma. annulifera, Anopheles Nigerrimus , An. annularis, An.maculatus, An. letifer, An. vagus, An. barbumbrosus, An. barbirostris and An. tesselatus. Mansoniauniformis and Anopheles Nigerrimus was confirmed as filariasis vector but none containing microfilariae.Breeding habitat of Anopheles have water temperature 280C — 300C and pH 7 with vegetation (grass andEichhornia crassipes / water hyacinth) and predator (Oreochromis niloticus / nile tilapia and Aplocheiluspanchax / fish head lead). Thus the community are expected to behave positively, especially avoidmosquito bites and manipulate the environment that potentially as mosquito larvae breeding habitat.
