Okinawa is the largest, most urbanized, and densely populated island in the Ryukyus
Archipelago, where mosquito species diversity has been thoroughly studied. However, the south-central
Okinawa mosquito fauna has been relatively poorly studied. Here, we present results from a mosquito faunal
survey in urban environments of Nishihara city, south-central Okinawa. Mosquitoes were sampled biweekly,
from April 2007 to March 2008, at 3 different environments: a forest preserve, an animal farm, and a water
reservoir. We employed 4 mosquito collection methods: 1) oviposition traps; 2) light traps; 3) sweep nets; and
4) larval surveys of tree holes, leaf axils, and artificial water containers. We collected a total of 568 adults and
10,270 larvae belonging to 6 genera and 13 species, including 6 species of medical importance: Aedes
albopictus, Armigeres subalbatus, Anopheles Hyrcanus group, Culex bitaeniorhynchus, Cx. quinquefasciatus,
and Cx. tritaeniorhynchus. Mosquito species composition was similar to data from previous studies in
Okinawa Island. The flattening of the species accumulation curve suggests that our diversity sampling was
exhaustive with light and oviposition traps, as well as the coincidence between the species richness we found
in the field and estimates from the Chao2 index, a theoretical estimator of species richness based on species
abundance. This study highlights the importance of combining several sampling techniques to properly
characterize regional mosquito fauna and to monitor changes in the presence of mosquito species. |
