Recent worsening of global dengue situation, geographical spread of the West Nile virus to the United States and the unexpected emergence of the Zika virus on the Yap island in the Pacific, have placed mosquito-borne flaviviruses in the limelight. Vector control remains as a key measure for prevention and control of these diseases. Mosquito borne flaviviruses are vectored by an array of mosquito species, with different behaviour and habitats. This chapter discusses the principles of vector control using Singapore's dengue control programme to illustrate a strategy for urban peridomestic Aedes mosquitoes; and control of rural WNV and JEV to demonstrate strategies for rural Culex mosquitoes. In both situations, the incorporation of measures that consider the complex interplay of factors, including disease ecology, vector bionomics, land use, human activities and other social economic development, is essential. Despite the different strategies demanded by different vectors of diverse ecology and bionomics, the organisational framework that guide vector control remains consistent. The management system demands cost-effectiveness, which seeks synergies among the various tools used, and among various stakeholders. Sustainability, insecticide resistance and negative impact on the environment remain as some of the challenges faced by vector control programmes read more ...
