Mosquito-borne avian malaria is a key limiting factor on Hawaiian forest bird populations. Preservation of endemic forest birds and restoration of Hawaiian forest bird communities will rely on mosquito control. While landscape level control is being developed, managers need short term and reliable tools for monitoring and controlling mosquito populations to protect remaining breeding bird populations. As part of a larger study looking at the efficacy of the biopesticide VectoMax FG for control of larval Culex quinquefasciatus, USGS and DOFAW personnel monitored adult mosquitoes (Culex quinquefasciatus and Aedes japonicus) along the Kawaikoi Stream during late summer, September through November 2016 and 2017. Ten...

Data included are DNA sequences used to identify species boundaries among Ichthyophonus-like parasites. Sequences were generated for three gene regions from each parasite isolate. DNA sequences can be downloaded from GenBank (https://www.ncbi.nlm.nih.gov/) as text or fasta files. Accession numbers for each sequence are included in the data table (.csv file). Data includes 87 sequences (99,383 total nucleotides). Once manuscript is accepted there are no restrictions on dissemination of these data.

As part of a larger study looking at the ecology and potential control of larval Culex quinquefasciatus, USGS and Hawaii DOFAW personnel surveyed a kilometer long reach of the Kawaikoi Stream for larval mosquitoes (Culex quinquefasciatus), potential larval mosquito habitat and non-target aquatic macroinvertebrates during late summer, September through November 2016 and 2017. Along each 10-meter section of the stream, 20 dip samples were taken (when possible) to record the presence of mosquito immatures (larvae and pupae) and macroinvertebrate encountered. Sampling was restricted to stream margins, perched pools, rock holes and back waters. No swift water was sampled. The number of discreet pools per 10-meter section...

While landscape level control is being developed managers need short term and reliable tools for monitoring and controlling mosquito populations to protect remaining breeding bird populations. As part of a larger study on the efficacy of the biopesticide VectoMax FG for control of larval Culex quinquefasciatus and adult mosquito traps for monitoring, USGS personnel evaluated host-seeking trap configurations and gravid trap lures for capturing adult mosquitoes (Culex quinquefasciatus and Aedes japonicus) in...

This data publication contains data files collected as part of a field, laboratory, and modeling effort aimed at uncovering ecological drivers of avian malaria transmission and impacts on Hawaiian honeycreepers across an elevational gradient on the eastern flank of Mauna Loa and Kilauea volcanoes on Hawaii Island. From 2001-2004, mosquito and bird data were collected at nine sites ranging 25 to 1,800 m above sea level. This data publication includes site and sampling coordinate data, mosquito capture data, mosquito avian malaria infection data, and point-transect distance sampling data. Site coordinate data consists of GPS spatial location data of sampling points where mosquitoes were captured and birds were surveyed...

As part of a larger study looking at the ecology and potential control of larval Culex quinquefasciatus, USGS and Hawaii DOFAW personnel monitored larval mosquitoes (Culex quinquefasciatus) and the non-target species Microvelia vagans and Megalagrion larvae in perched stream pools, seeps and ground pools along the Kawaikoi Stream during late summer, September through November 2016 and 2017. Pools were sampled before and following treatment with the biopesticide VectoMax FG at 1, 2, 7, 14, and 21 days post treatment to determine the efficacy of control and potential non-target effects. Only pools with mosquito larvae were treated although paired, untreated pools were also sampled to serve as controls for the non-target...

As part of a larger study looking at the efficacy of the biopesticide VectoMax FG for control of larval Culex quinquefasciatus, USGS and DOFAW personnel monitored adult mosquitoes (Culex quinquefasciatus and Aedes japonicus) along the Kawaikoi Stream during late summer, September through November 2016 and 2017. Ten trap sites were selected across a 1-kilometer grid centered on the intersection of the Alakai Swamp Trail and Kawaikoi Stream, Alakai Wilderness Preserve, Kauai. Traps were located at least 200 meters apart at accessible sites along the stream, valley floor, and adjacent plateau. Both Biogents Sentinel Traps (BGS) and Centers for Disease Control and Prevention (CDC) Gravid Traps (GRV) were operated nightly...

Mosquito-borne avian malaria is a key limiting factor on Hawaiian forest bird populations. Preservation of endemic forest birds and restoration of Hawaiian forest bird communities will rely on mosquito control. While landscape level control is being developed managers need short term and reliable tools for monitoring and controlling mosquito populations to protect remaining breeding bird populations.This dataset consists of site coordinates on Kauai and Hawaii Island where trapping of adult mosquitoes, surveys for larval mosquitoes and biopesticide efficacy trials occurred during 2016 and 2017.
As part of a larger study on the efficacy of the biopesticide VectoMax FG for control of larval Culex quinquefasciatus and adult mosquito traps for monitoring, USGS personnel evaluated host-seeking trap configurations and attractants as well as infusions for gravid trap for capturing adult mosquitoes (Culex quinquefasciatus and Aedes japonicus) in native forest habitat from August to November 2017. Four trap sites were selected in a forest tract in Volcano Village. Traps were arranged in a 100-meter square and trap types and lures were rotated through each site during each week of the study in a latin square design. Both host-seeking traps (Biogents Sentinel Traps and Centers for Disease Control and Prevention (CDC)...

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...
