Dynamics and diversity of bacteria associated with the disease vectors Aedes aegypti and Aedes albopictus

Abstract Aedes aegypti and Aedes albopictus develop in the same aquatic sites where they encounter microorganisms that influence their life history and capacity to transmit human arboviruses. Some bacteria such as Wolbachia are currently being considered for the control of Dengue, Chikungunya and Zi...
