Culex quinquefasciatus is the vector of the avian malaria Plasmodium relictum, a key limiting factor of endemic Hawaiian forest birds. The main components of the study included: (1) adult mosquito monitoring to document the altitudinal distribution, seasonal occurrence, relative abundance, and trapping efficacy of Culex quinquefasciatus (K\u012bpahulu Valley, Maui, 1 file); (2) stream surveys to determine the larval habitat availability and prevalence of larval mosquitoes (K\u012bpahulu Valley, Maui, 1 file), (3) characterization of larval habitat (K\u012bpahulu Valley, Maui, 1 file), (4) egg viability (hatching rate) in naturally occurring Culex quinquefasciatus populations (K\u012bpahulu Valley, Maui and Volcano, Island of Hawai'i, 2 files) and (5) the geographical coordinates for key localities in the study (K\u012bpahulu  Valley, Maui and Volcano, Island of Hawai'i, 1 file). The study was conducted by U.S. Geological Survey, Pacific Island Ecosystems Research Center personnel in collaboration with National Park Service, Pacific Island Inventory and Monitoring Network, Haleakal\u0101 National Park and Hawai\u2018i Volcanoes National Park. Studies were conducted in native forests on Maui and the Island of Hawai'i during 2022 and 2023.\nFirst posted - September 6, 2024 (available from author)\nRevised - January 2026 (version 2.0)", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P13UJFWU", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.65a878b5d34ebad3f34cc2df.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_65a878b5d34ebad3f34cc2df", "keyword": ["Haleakal\u0101 National Park", "Hawai'i Island", "Hawai'i Volcanoes National Park", "Hawaiian Islands", "Kauai", "K\u012bpahulu Valley", "Palikea Stream", "USGS:65a878b5d34ebad3f34cc2df", "avian malaria", "biota", "extinction", "health", "incompatible insect technique", "kiwikiu", "mosquito monitoring", "wildlife disease"], "modified": "2026-03-12T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-156.7255, 18.7191, -154.5941, 21.1460", "theme": ["geospatial"], "title": "K\u012bpahulu Valley, Haleakal\u0101 National Park, Maui Seasonal Distribution and Relative Abundance of the Mosquito Culex quinquefasciatus, 2022-2023 (ver. 2.0, March 2026)"}
