Dispersal of Engineered Male Aedes aegypti Mosquitoes.
BACKGROUND:Aedes aegypti, the principal vector of dengue fever, have been genetically engineered for use in a sterile insect control programme. To improve our understanding of the dispersal ecology of mosquitoes and to inform appropriate release strategies of 'genetically sterile' male Aed...
