SINGAPORE: Male Wolbachia-carrying mosquitoes have been released in expanded sites in Nee Soon and Tampines, under the next phase of a study to reduce the Aedes mosquito population and fight dengue.
The third phase of the National Environment Agency's (NEA) Project Wolbachia kicked off on Friday (Feb 22), with the mosquitoes released at Nee Soon East and Tampines West sites that are 1.6 to 2.2 times larger compared to the trial area in phase two.
These male mosquitoes infected with the Wolbachia bacterium do not bite or transmit diseases. If they mate with an uninfected female mosquito, the resulting eggs will not hatch.
The purpose of expanding the sites is to determine if suppression of the urban Aedes aegypti mosquito population can be sustained in larger areas, said NEA.

The study says that land use changes, pollution, and climate change are all causing biodiversity loss.
