Wolbachia dengue-fighting study completed, 50% suppression rate noted, phase 2 to start next year: NEA
The study showed that 50 per cent fewer adult mosquitoes were found in sites where male Wolbachia-Aedes mosquitoes were released, compared with sites where no Wolbachia-Aedes mosquitoes were released.

SINGAPORE - The first phase of a study on Wolbachia-bacteria-carrying mosquitoes has been completed, with successful suppression of half the targeted Aedes aegypti population observed during the study, the National Environment Agency (NEA) said on Friday (Dec 8).
In October last year, NEA started the first phase of the field study at Braddell Heights, followed by Tampines West and Nee Soon East a month later.
When male mosquitoes carrying the naturally occurring Wolbachia bacteria mated with female mosquitoes, the bacteria caused the females to produce eggs that did not hatch.
The aim of this was to reduce the Aedes aegypti population, which transmits the viruses that cause dengue fever. These mosquitoes also carry the chikungunya and Zika viruses.
Phase 1 of the study has met its objectives and a second recommended phase will commence in the second quarter of next year, NEA said.
Phase 1 of the study showed that Wolbachia technology has the potential to suppress the Aedes aegypti mosquito population, as half of the Aedes mosquito eggs collected from release sites did not hatch...
