Summary: It has been known that the mosquitoes which transmit malaria have restricted distributions in the South West Pacific Region but the geographical range limits of individual species as well as the factors which define their ranges were not clearly understood. Our research has revealed that climate and other environmental variables influence range and abundance. Computer modelling studies show that different combinations of environmental factors are associated with presence or absence of the various species. Spatial analysis of species presence records and historical weather data has permitted accurate prediction of the geographical ranges of the different mosquito species in the region. This new knowledge on species range limits and the factors which influence vector distribution should enable control efforts to focus more efficiently against the mosquitoes which transmit malaria in this part of the world.
