Google plans to release 32 million mosquitoes in the United States! "Biological Debug Experiment" to combat dengue fever sparks heated discussion

Google has applied to release 32 million special male mosquitoes in the U.S., using AI and automation technology to block reproduction. It is claimed that the Debug project previously succeeded in reducing more than 70% of dengue fever cases in Singapore.

Google applies to release 32 million mosquitoes in the wild in California and Florida

Google’s mosquito-release experiment, a move by the tech giant, has sparked heated discussion among U.S. internet users. According to a report by the UK’s The Guardian, Google has recently submitted an application to the U.S. government, planning to release 32 million specially treated male mosquitoes in California and Florida within two years.

Named Debug, the program focuses on applying technology and data science to the field of global public health. Google hopes to reduce the number of deadly mosquitoes in the wild through biotechnology that uses good insects to control bad insects.

Currently, the U.S. Environmental Protection Agency (EPA) is reviewing this experimental use permit, and the public comment period will end on June 5, 2026. After evaluation, the authorities will decide whether to approve it.

The core technology of the mosquito-release program is natural Wolbachia

According to Google’s official article, this Debug program, which has lasted more than 10 years, is centered on using naturally occurring symbiotic bacteria—Wolbachia.

Scientists infect male mosquitoes with this bacterium in the laboratory. After they are released into the wild and mate with wild female mosquitoes, the eggs laid by the females will not hatch, thereby reducing the mosquito population. Because only female mosquitoes bite, releasing male mosquitoes does not increase the risk of residents being bitten.

Data from the U.S. Centers for Disease Control and Prevention (CDC) shows that West Nile virus is the main mosquito-borne disease in the United States.

Chad Huff, a public information officer from the Florida Keys Mosquito Control District, pointed out that this technology targets Culex mosquitoes, also known as “mosquitoes that transmit West Nile virus and St. Louis encephalitis.” In some trial areas, the number of mosquitoes has already been reduced.

Introducing AI and automation equipment to raise male mosquitoes to block reproduction

The program was originally developed by Verily, a company under Alphabet, Google’s parent company, and in December 2024, Google fully acquired it.

Google engineers use artificial intelligence (AI) computer-vision technology to precisely sort mosquitoes by sex during production, and increase output through automated robots, then combine this with delivery vehicles equipped with GPS to ensure the mosquitoes are released accurately in the right locations.

Singapore experiment successfully reduced 70% of dengue fever cases

Before applying in the U.S., the Google Debug program had already been tested in Singapore.

Since 2018, Debug has worked with Singapore’s National Environment Agency (NEA) to promote the program, and in 2022, a breeding facility was put into operation. By 2024, the program was releasing 6 million male mosquitoes per week, and weekly release volumes have already exceeded 10 million.

Official trial data shows that after continuous releases for 6 to 12 months, the number of Aedes aegypti in the trial area successfully decreased by 80% to 90%, and local dengue fever infection cases fell by more than 70%.

Currently, nearly 4 billion people worldwide are threatened by dengue fever, and Asia alone bears 70% of the disease burden.

Debug program leader Linus Upson said that the original goal of launching the program in Singapore was to improve the efficiency of mosquito production and release through technology, and bring this technology to more communities in Asia affected by dengue fever.

He emphasized that the success achieved in Singapore has given the team confidence to further expand its global rollout.
