BIOTEKNOLOGI VEKTOR MALARIA NYAMUK Anopheles sundaicus DI KECAMATAN NONGSA, KOTA BATAM, TAHUN 2008

Abstract


Malaria was one of the vector-borne diseases that still becoming a health problem in Indonesia. It closely related with the environment condition. The case of malaria in Nongsa subdistrict was high with the highest Annual Parasite Incidence (API) in Sambau village was 34%o in 2007, whereas in Batu Besar village 2.3%o. The aim of this research was to know bionomic of An.sundaicus malaria vector in Nongsa subdistrict that covered mapping of larvae habitat, density of vector mosquitoes, biting activity, parous rate, vector incrimination as well as sensitivity status to insecticide. The study hold by catching mosquitos with human trap indoor/outdoor and wall resting start on 06.00 PM until 6.00 AM. The larva survey with technique searching in the morning. The results of habitat mapping in the village of Teluk Mata Ikan and Batu Besar found one type of An.sundaicus larvae habitat in the former sand quarry with water salinity between 5-12%o, pH 7 and water temperatures between 29-33°C. The results of An. sundaicus caught in July showed that outdoor Man Biting Rate (MBR) 4,7 and indoor 3,0. On October 2008, outdoor Man Biting Rate (MBR) were 2.8 and indoor 0.8, whereas in December, the density of An. sundaicus caught outdoor 35.5 and indoor 18.7. An.sundaicus blood sucking activity expressed in the Man Hour Density (MHD) in July as the highest, outdoor between the hours of 02.00 to 03.00 AM and outdoor between the hours of 04.00 to 05.00 AM. In October, the highest outdoor was between the hours of 04.00 to 05.00 AM, indoor between the hours of 03.00 to 04.00 AM and 01.00 to 02.00 AM. In December, the highest outdoor was between the hours of 23.00-24.00 and indoor between the hours of 01.00 to 02.00 AM and 03.00 to 04.00 AM. The results of ELISA test to circum sporozoite protein found containing 14.01% P. falciparum and 5.68% of P.vivax. Besides, it also found that An. sundaicus containing 2 types of Plasmodium sp (mix). The results of testing susceptibility to insecticides found that An.sundaicus still vulnerable to Bendiocarb (0.1%) and Deltamethrin (0.05%) insecticides.
