Summary
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 larval habitat [...]

An additional data file contains geographical coordinates for key localities in the study. The study was conducted by The US Geological Survey, Pacific Island Ecosystems Research Center personnel in collaboration wth biologists with the Kauai Forest Bird Recovery Project. Studies were conducted in native forests on Kauai and Hawaii islands during 2016 and 2017.

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. These data allow for the evaluation of VectoMax FG as a suitable control measure for local populations of Culex quinquefasciatus and efficacy of several mosquito trap types and lures for monitoring low density mosquito populations. Other data collected provide basic biology on 1) the type and relative abundance of larval habitat used by Culex quinquefasciastus, 2) the relative abundance of adult mosquitoes at the Kawaikoi Stream study site and 3) the prevalence of malarial infection in mosquitoes. The data could be used to develop local control strategies for mosquito control, disease risk assessment and population analysis and modeling.
