Diseases caused by arboviruses transmitted by Aedes aegypti, such as dengue, 
chikungunya and Zika continue to rise in annual incidence and geographic 
expansion. A key limitation for achieving control of Ae. aegypti has been the 
lack of effective tools for monitoring its population, and thus determine what 
control measures actually work. Surveillance of Ae. aegypti has been based 
mainly on immature indexes, but they bear little relation to the number of 
mosquito females, which are the ones capable of transmitting the viruses. The 
recent development of sampling techniques for adults of this vector species 
promises to facilitate surveillance and control activities. In this review, the 
various monitoring techniques for this mosquito are presented, along with a 
discussion of their usefulness, and recommendations for improved entomological 
surveillance.
