Characterization of the Aedes aegypti population on an island field site in Vietnam

We have now assessed the long-term seasonal abundance and spatial distribution of Ae. aegypti as a precursor to the development of a vector control strategy based on the release of wMelPop transinfected mosquitoes. For the small island field site of approximately 600 households, we estimated an upper Ae. aegypti population size of 26,000 adult female mosquitoes. Therefore, for a Wolbachia-based intervention, we envisage that multiple, broad scale releases from numerous locations in the village (as opposed to a few, focal releases) will most likely be required – this will counteract any spatial heterogeneity, dampen the effect of transient key premises and enhance movement rates of Wolbachia.
