SUMMARY
The host preference is used in mathematic calculation of vectorial capacity. Annual Parasite Incidence (API) of malaria incident showed increasing in Srumbung sub district, Magelang regency for 2001-2003. Data about host preference identification of Anopheles, either vector or estimated vector in Magelang regency has not been providing yet. We will know Anopheles sp. host preference in Srumbung sub district, Magelang regency, Central Java from the research. The research was done by Anopheles sp. capturing at the morning and the afternoon, Mosquitoes captured, were identified their species and selected in order to get mosquitoes with blood fed or half gravid abdomen condition. Mosquito's abdomen was crushed on Whatman filter paper and tested with EliSA technique. The research result indicated that 10 species of Anopheles sp. in Srumbung sub district, Magelang regency are Anopheles vagus, An. jlavirostris, An. balabacensis, An. aconitus. An. maculalus, An. barbirostris, An. bengalensis, An. kochi. Anopheles minimus and An. subalbatus (further confirmation is needed). ELISA blood meals test resulted mosquitoes which consumed human blood meals are An. balabacensis 9,76% (from 82 specimens), An. flavirostris 9,09% (from 33 specimens). An. vagus 5,8% (from 69 specimens) and An. aconitus 4% (from 25 specimens). The presence of Anopheles as vector of malaria (Anopheles balabacensis dan An. aconitus) which consumes human blood meal in Srumbung sub district, Magelang regency means that Srumbung sub district is potential for malaria transmission. The presence of the cattle can reduces risk of malaria transmission. The cattle can becomes a barrier or the effort to reduce contact between human and Anopheles.
