Abstract

Background: Dengue suppression often relies on control of the mosquito vector, Aedes aegypti , through applications of insecticides of which the pyrethroid group has played a dominant role. Insecticide resistance is prevalent in Ae . aegypti around the world and the resulting reduction of insecticide efficacy is likely to exacerbate the impact of dengue. Dengue has been a public health problem in Saudi Arabia, particularly in Jeddah, since its discovery there in the 1990s and insecticide use for vector control is widespread throughout the city. An alternative approach to insecticide use, based on blocking dengue transmission in mosquitoes by the endosymbiont Wolbachia , is being trialled in..
