How does releasing male Wolbachia-Aedes mosquitoes suppress Aedes aegypti populations?
- When male Wolbachia-carrying Aedes aegypti (Wolbachia-Aedes) mosquitoes mate with urban female Aedes aegypti that do not carry Wolbachia, their resulting eggs do not hatch.

Over time, continued releases of male Wolbachia-Aedes mosquitoes will lead to a decline in urban Aedes aegypti populations. This not only reduces the risk of dengue, but also of other Aedes aegypti-borne diseases such as Zika and chikungunya.
The science behind Wolbachia-Aedes suppression technology
Read on for a more detailed look at the biology behind Wolbachia-Aedes suppression technology. You’ll also find out more about the studies NEA has done to ensure that the male Wolbachia-Aedes mosquitoes we release will be effective at suppressing Aedes aegypti populations.
