Ogan Komering Ulu (OKU) District is one of dengue endemic areas in South Sumatera Province. One of the effort to prevent the occurrence of DHF transmission is by controlling mosquito vectors at the larval level. The use of insecticides in the control of DHF vectors, in addition to causing resistance, can also adversely affect the environmental health. Currently, DBD vector control in OKU District is done biologically (biological control), that is by using larvae-eating fish. This study was conducted to determine the level of community participation in the control of dengue vectors using larvae-eating fish. The research location was in Baturaja Lama and Sekarjaya village. The population was all households in both urban villages. The number of samples was determined by reference to the WHO provisions on the minimum standard of DBD entomology survey sample that is 100 houses, the number of household samples that were obtained was 217 chosen by purposive method. The result of index calculation of larvae showed the number of HI in Baturaja Lama village was 42,1% and Sekar Jaya village was 48,2%. CI figures in the Baturaja Lama village was 19.2% and Sekar Jaya village was 16.2%. BI figures in Baturaja Lama village was 51.4% and Sekar Jaya village was 75.5%. Fishing behavior showed significant correlation to larva existence, but the percentage of households maintaining fish in the two sub-districts was low, less than 10%. It is necessary to increase the community's knowledge about the benefits and potential development of larvae-eating fish species in the effort of controlling DHF.
