Asian Scientist Journal (Jul. 18, 2022) — It may appear counterintuitive to skinny out a crowd by including extra folks to it; however with regards to Singapore’s dengue-carrying mosquito downside, that is perhaps a surprisingly efficient resolution.
Since 2016, the Nationwide Environmental Company (NEA) of Singapore has been investigating how some specialised bug-carrying bugs would possibly complement present dengue management measures, below a program known as Mission Wolbachia.
Naturally, the Aedes aegypti mosquitoes being launched by the NEA among the many nation’s high-rise neighborhoods aren’t any strange crowd of bugs. For one, they’re all male, that means they don’t chew; for an additional, they don’t carry the dengue virus; and uniquely, they’ve all been bred to hold a bacterium known as Wolbachia inside their our bodies.
When these male mosquitoes breed with females out within the area, this bacterium will get handed on to their eggs—and stops them from hatching totally.
The lead to area trials to this point, in keeping with Affiliate Professor Ng Lee-Ching, could be a steep crash within the native A. aegypti inhabitants—as much as 98 p.c in some residential neighbourhoods—and a simultaneous plunge in native dengue fever circumstances. Ng, group director of the NEA’s Environmental Well being Institute, is a part of Mission Wolbachia.
“Globally, [Project Wolbachia] is the primary such research in a high-rise panorama,” stated Ng. “Because the undertaking expands, the completely different terrain and places have given us completely different information factors and classes which have enabled us to scale up.”
Constructing on the undertaking’s promising outcomes, in June 2022 the NEA introduced it will increase area trials to eight extra websites in Singapore. These will cowl an extra 1,400 Housing Improvement Board (HDB) blocks, bringing the whole protection of Mission Wolbachia to 31 p.c of all such public housing within the nation.
However simply how do an obscure bacterium and an notorious mosquito—the commonest service of the dengue virus in city environments—mix to type a novel instrument in an age-old public well being battle? Ng explains extra about Mission Wolbachia in an interview with Asian Scientist Journal.
