Karakteristik Habitat Larva Anopheles Spp. Di Desa Sungai Nyamuk, Daerah Endemik Malaria Di Kabupaten Nunukan, Kalimantan Utara

A research about Habitat Characteristics of Anopheles spp. larvae was done in Sungai Nyamuk Village, Nunukan District, North Kalimantan Province from August 2010 to January 2012. This research aims to analyse the characteristics of breeding places of Anopheles spp. The larvae taken from various types of habitat with detention and maintained until it was developed into mosquitoes, then later identified. The results showed that there are four types of potential breeding places of Anopheles spp. ie lagoon, ditches, fish ponds and marshes. Anopheles types that are found consist of five species, namely An. vagus, An. subpictus, An. sundaicus, An. indefinitus dan An. peditaeniatus. Types of potential breeding places are dominated by the unused fish pond, with the substrate in the form of mud and water is not flowing, located around settlements surrounded by grasses, shrubs and trees. Breeding places contains of aquatic plants such as grasses and moss. Predators are found in the form of a dragonfly nymph, crustaceans, tadpoles and small fish. Early malaria vector control at the level of the larvae is a critical point of the success of malaria elimination programs in endemic areas
