Project Wolbachia: Residents are killing the ‘helpful’ mosquitoes, which can be a nuisance

T. J. Cheng,  today,  2021.

Since the full scale implementation of Project Wolbachia in Tampines last year, residents such as myself have had mosquitoes invading our homes frequently.   In 2019, Dr Amy Khor, then Senior Minister of State for the Environment and Water Resources, said that there was a 90 per cent suppression rate at study sites in Tampines and Yishun from February to November that year. However, certain public housing estates under the project were still dengue hot zones last year.The idea of the project is to have the male Aedes mosquitoes, which are injected with the Wolbachia bacteria, mate with female Aedes aegypti mosquitoes. The females then go on to lay eggs that do not hatch, effectively suppressing their numbers.
