Google subsidiary expands mosquito facility in Singapore to strengthen anti-dengue efforts

Google subsidiary Debug is expanding its mosquito production facility in Kaki Bukit, Singapore, from 20,000 to 28,000 square feet to enhance its efforts in combating dengue. The company plans to increase its workforce, including software engineers and mosquito biologists, to support this growth. Debug currently produces over 10 million male Aedes mosquitoes weekly, which are infected with Wolbachia bacteria to reduce the local mosquito population and dengue transmission. This expansion aims to further automate mosquito production and improve AI-driven sex-sorting technology. Debug’s work supports Singapore’s Project Wolbachia, launched in 2016, which involves releasing lab-grown male mosquitoes carrying Wolbachia. These males mate with wild females, resulting in eggs that fail to hatch and thus suppressing the mosquito population. The project has achieved significant success, reducing Aedes aegypti populations by 80 to 90 percent in treated areas and lowering dengue risk by 70 percent for residents. Debug began as a Verily Life Sciences initiative, a Google parent Alphabet company, and partnered with Singapore’s National Environment Agency (NEA) in 2018 to trial its automated mosquito sorting and release technologies. Debug’s Kaki Bukit facility is one of two in Singapore producing Wolbachia-infected mosquitoes, with the NEA operating the other. The NEA’s facility produces around five million mosquitoes weekly, while Debug has increased its output from six million in 2024 to over 10 million today. The expansion will enable Debug to scale production further by integrating automation across the mosquito rearing lifecycle, enhancing both yield and quality. Despite plans for a third NEA facility encountering tender challenges, Debug’s growth positions it as a regional research and development hub for mosquito-borne disease control. This initiative is critical as dengue fever remains a major public health concern in tropical regions. Debug’s advancements in AI and automation represent a promising approach to sustainable vector control, potentially serving as a model for other countries facing similar challenges. The expanded facility and increased production capacity could accelerate efforts to reduce dengue incidence and improve public health outcomes in Singapore and beyond.
