This USGS data release consists of seven data sets and accompanying metadata for studies on the efficacy of adult mosquito traps and lures for monitoring populations of the invasive mosquito Culex quinquefasciatus and the efficacy of the biopesticide VectoMax FG for control of larval Culex quinquefasciatus in Hawaiian forest bird habitat. Culex quinquefasciatus is the vector of the avian malaria Plasmodium relictum a key limiting factor of forest birds. The main components of the study included: 1) the evaluation of trap designs and lures for adult mosquitoes in forested habitat and the prevalence of malaria in those mosquitoes (Hawaii Island 2 data files), 2) Kawaikoi Stream surveys for larval mosquitoes and suitable...
Rapid ʻŌhiʻa Death is a fatal disease caused by Ceratocystis lukuohia and C. huliohia that are decimating Hawaiʻiʻs keystone trees species, ʻōhiʻa (Metrosideros polymorpha). We developed practical and effective decontamination practices for both cultured C. lukuohia and C. huliohia as well as Ceratocystis spores embedded in ambrosia beetle frass (fine particles of macerated wood or boring dust, beetle parts, and feces). This data release includes data and metadata containing decontamination results of ambrosia beetle (Coleoptera: Scolytinae) frass contaminated with Ceratocystis lukuohia propagules using various laboratory and household disinfectants.
The yǻyaguak (Mariana swiftlet; Aerodramus bartschi) is an endangered cave-nesting species historically found on Guam and the southern Mariana Islands, Micronesia. The population on Guam has been severely impacted by the introduction of the brown treesnake (Boiga irregularis). Population status assessments have, however, been challenging due to the limitations of traditional counting methods, which rely on visual observations at cave entrances and are prone to inaccuracies. To improve count accuracy, we estimated yǻyaguak population size and relative nesting activity using thermal and near-infrared videography at Mahlac, Maemong and Fachi Caves from April 2019 to April 2023. This study demonstrates the potential...
These two raster data layers depict the land cover and degree of human disturbance to plant communities on the seven main Hawaiian Islands, and were developed as part of a comprehensive USGS assessment of carbon sequestration potential by natural ecosystems in the State of Hawaii.
