Entomological surveillance of Aedes mosquitoes is used for operational (and research) purposes to determine changes in geographical distribution, for monitoring and evaluating control programmes, for obtaining relative measurements of the vector population over time, and for facilitating appropriate and timely decisions regarding interventions. There are a number of methods for monitoring vectors (mostly Aedes aegypti) of arboviral diseases. However, the selection and use of a method requires a clear understanding of the surveillance objectives, the availability of skills and resources, and in some instances the level of infestation.

This document describes selected sampling methods that can be used to conduct surveillance of Aedes mosquitoes, pupae and oviposition. It is intended for qualified entomologists at national and sub-national level who are responsible for the surveillance of local Aedes populations.
