Species composition of mosquito and public perception about Dengue vector of hemorrhagic fever in Bareng Tenes Malang

Dengue Hemorrhagic Fever (DHF) is a mosquito-borne tropical disease caused by the dengue virus. Aedes aegypti and Aedes albopictus are the mosquito vectors of DHF. Malang city was an endemic region of dengue disease in East Java. One of the villages that had a high number of DHF cases was Bareng Tenes. The Case Fatality Rate (CFR) in Malang city totaled 5 patients out of 879 cases (Health Department of Malang city, 2010). Bareng Tenes RW 02 was one of the densely populated regions of Malang city. The objectives of this research were to identify mosquito composition and to analyze the public perception about the DHF vectors in Bareng Tenes RW 02 Malang. This research used two kinds of survey methods of mosquitoes. The first method for collecting larvae was used by direct capture using pipettes from artificial containers and the second method was collecting egg of mosquitoes by using an ovitrap. Public perception was calculated using the questionnaire technique. The accidental sampling technique in this research was Likert scale. The composition of mosquitoes found in Bareng Tenes RW 02 was Aedes aegypti, Aedes albopictus and Culex quinquefasciatus. The mosquito survey showed that Aedes aegypti was the dominant species and the IVI value for the ovitrap survey was 118.06% while the value of IVI for the larval survey was 103.51%. Based on the public perception data, it showed that the community has a very good understanding of DHF knowledge, DHF vectors and ways of DHF prevention, but the undertaken activities by the community have not yet appeared to control the mosquito population especially for their larvae.
