Summary

As part of a larger study looking at the seasonal distribution and relative abundance of the southern house mosquito Culex quinquefasciatus in Kīpahulu Valley, Haleakalā National Park, adult mosquito distribution and abundance was monitored at two altitudinal sites throughout the year. Study sites at Delta Camp (915 m asl) and Palikea Camp (1280 m asl) were visited twice during each three-month season from September 2022 to September 2023. At each study site, 15 BioGents (BG) Sentinel II traps (S), 15 BioGents Pro traps (P), and 15 Center for Disease Control (CDC) Gravid traps (G) were operated for 4-7 nights across a 1-kilometer square area. CO2 baited traps (S and P) were operated at 30 fixed transect stations located 100 meters [...]

Purpose

Kīpahulu Biological Reserve in Haleakalā NP (HALE) is nationally and globally significant as one of the most remote, intact, dramatic valleys in the Pacific containing remarkable biodiversity found nowhere else on the planet. It is critical habitat for 6 Hawaiian honeycreepers, including 3 endemic to Maui: the critically-endangered ‘Ākohekohe (Palmeria dolei), critically-endangered Kiwikiu (Pseudonestor xanthophrys), and endangered Maui ʻAlauahio (Paroreomyza montana). Populations of these endangered species have declined dramatically over recent decades. Mosquito-borne avian malaria exacerbated by climate change is the key limiting factor of Hawaiian forest bird populations. Preservation of endemic forest birds and restoration of Hawaiian forest bird communities in Kīpahulu Valley will rely on landscape-scale mosquito control such as Wolbachia-based Incompatible Insect Technique (IIT). The mosquito trap capture data can be used to estimate densities and occupancy rates of mosquitoes and to guide control efforts both geographically and temporally to be most efficacious.Trap capture data can also be used for determining the most efficient trap technology and trapping effort to employ for successful monitoring of Culex quinquefasciatus populations.
