Singapore (VNA) – Singapore’s National Environment Agency (NEA) onDecember 2 launched a new facility that can breed millions of male mosquitoes aweek to prevent urban female Aedes aegypti mosquitoes from producing offspring.

This comes in the wake of a surge of dengue cases in Singapore this year, withclose to 15,000 cases and 20 deaths reported.

The new facility will allow the NEA to scale up Wolbachia Project by producingup to 5 million male mosquitoes a week. The project involves the release ofmale Wolbachia-Aedes aegypti mosquitoes to suppress the urban Aedes aegyptimosquito population, which is the primary vector of dengue, chikungunya andZika here.

When the released male Wolbachia-Aedes aegypti mosquitoes mate with urbanfemale Aedes aegypti ones that do not carry Wolbachia, the eggs do not hatch.

NEA said that over time, the continued release of maleWolbachia-Aedes aegypti mosquitoes is expected to bring about a gradualreduction in the urban Aedes aegypti mosquito population, and hence lower therisk of dengue transmission.

Speaking at the launch of the new facility, Senior Minister ofState for the Environment and Water Resources Amy Khor, who is also SeniorMinister of State for Health, said the dengue situation is likely to worsenover the next few decades as a result of global warming.

Higher temperatures result in mosquitoes breeding faster and causethe dengue virus to replicate at a quicker rate, she explained./.
