750 million genetically engineered mosquitoes approved for release in Florida Keys
More than 750 million genetically modified mosquitoes will be released into the Florida Keys in 2021 and 2022.
The plan received final approval from local authorities, against the objection of many local residents and a coalition of environmental advocacy groups.
The mosquito is also approved to be released into Harris County, Texas, beginning in 2021, according to Oxitec, the U.S.-owned, British-based company that developed the genetically modified organism (GMO).
The Environmental Protection Agency granted Oxitec’s request after years of investigating the impact of the genetically altered mosquito on human and environmental health.
“This is an exciting development because it represents the ground-breaking work of hundreds of passionate people over more than a decade in multiple countries, all of whom want to protect communities from dengue, Zika, yellow fever, and other vector-borne diseases,” said Oxitec CEO Grey Frandsen.
A long fight in Florida
In June the state of Florida issued an Experimental Use Permit after seven state agencies unanimously approved the project. But it’s taken over a decade to obtain that approval.
In 2009 and 2010, local outbreaks of dengue fever, which is spread by the Aedes aegypti, left the Florida Keys Mosquito Control District desperate for new options. Despite an avalanche of effort — from aerial, truck and backpack spraying to the use of mosquito-eating fish — local control efforts to contain the Aedes aegypti with larvicide and pesticide had been largely ineffective.
And costly, too. Even though Aedes aegypti is only 1% of its mosquito population, Florida Keys Mosquito Control typically budgets more than $1 million a year, a full tenth of its total funding, to fighting it.
In 2012, the district reached out to Oxitec for help. The company had developed a male mosquito named OX513A, programmed to die before adulthood unless it was grown in water that contained the antibiotic tetracycline.
Batches of the sterile OX513A would be allowed to live and mate with females; however, their male and female offspring would inherit the “kill” programming and die, thus limiting population growth.
OX513A had been field tested in the Cayman Islands, Panama and Brazil, with Oxitec reporting a large success rate with each release. For example, a trial in an urban area of Brazil reduced the Aedes aegypti by 95%.
Apparently their definition of ‘large success’ differs from the environmental health minister in the Cayman Islands.
But when word spread in the Florida Keys that the mosquito was on the way, public backlash was swift: More than 242,000 people signed a Change.org petition against the proposal.
Public relations campaigns reminding Floridians that the GMO mosquito doesn’t bite because he’s male didn’t completely solve the problem. Media reports quoted angry residents refusing to be treated as “guinea pigs” for the “superbug” or “Robo-Frankenstein” mosquito.
The EPA spent years investigating the mosquito’s impact on both human health and the environment, allowing time for public input. But in the midst of the evaluation, Oxitec developed a second-generation “Friendly Mosquito” technology and withdrew the application for the first.
The new male mosquito, OX5034, is programmed to kill only female mosquitoes, with males surviving for multiple generations and passing along the modified genes to subsequent male offspring.
The EPA permit requires Oxitec to notify state officials 72 hours before releasing the mosquitoes and conduct ongoing tests for at least 10 weeks to ensure none of the female mosquitoes reach adulthood.
However, environmental groups worry that the spread of the genetically modified male genes into the wild population could potentially harm threatened and endangered species of birds, insects and mammals that feed on the mosquitoes.
So, do you think these genetically engineered mosquitoes will help or will only help to develop new mutant and resistant insects that could become the next plague? More on Strange Sounds and Steve Quayle. [CTV News]
