Ecological distribution of mosquito larvae of the Anopheles punctulatus group on Niolam (Lihir) Island, Papua New Guinea.
We surveyed the larval habitats of members of the Anopheles punctulatus group of mosquitoes on Niolam (Lihir) Island, Papua New Guinea. Identification of this group was undertaken by polymerase chain reaction-restriction fragment length polymorphism analysis of the amplified internal transcribed spacer unit 2 of rDNA, because morphologic separation of member species is unreliable. The most widespread malaria vector species and their most common larval habitats were identified to aid source-reduction programs for malaria control. The most ubiquitous species was An. punctulatus, followed by An. farauti no. 2. then An. farauti s.s. Anopheles punctulatus has increased relative to An. farauti s.l. since the start of development projects on Lihir Island. The most common larval habitats were shallow temporary pools with clay substrate and with plants or floatage. These habitats, mostly encountered alongside poorly drained roads, may be increased by development projects.
