BACKGROUND: Biak Numfor regency had high number of malaria cases in Papua Province. This regency is an area with coastal ecosystem. Anopheles farauti was reported as one of the main vectors of malaria in Papua. Vector capacity (VC) is a quantitative entomology indicator used to measure contagious potency of malaria in endemic areas. Vectorial capaci-ty is the rate (usually daily) at which a bloodsucking insect population generates new inoculations from a currently infectious case. Vectorial capacity is the product of the eight components; vector longevity is a key component. It is a measure of potential rather than actual rate of transmis-sion, because it includes no parasitological information. This study aimed to estimate VC of An. farauti Laveran (Diptera: Culicidae), and to deter-mine its relationship with of malaria cases in Biak Numfor regency.

SUBJECT AND METHODS: Methods used to calculate VC values were: (1) Human landing collection, (2) Ovarial surgery, and (3) ELISA test. Data of malaria cases were obtained from the Regency Health Office of Biak Numfor.

RESULTS: Vector capacity values in Biak Numfor coastal ecosystem were within the range between <0.01 to 0.05. This result indicated that Anopheles farauti mosquito was a potential malaria vector and it increase-ed the contagious risk of malaria in coastal ecosystem.

Anopheles farauti mosquito is a potential malaria vector and it increases the contagious risk of malaria in Biak Numfor coastal ecosystem.
