After years of intense debate between pros and cons, the first genetically engineered yellow fever mosquitoes (Aedes aegypti) have been released on the Florida Keys to combat diseases such as dengue fever and Zika virus. The project stipulates that 12,000 male GMO larvae will be released every week within 12 weeks; once they reach adulthood, they will transmit a lethal gene that can kill female larvae.
inside Florida KeysFlorida Keys, scientists have begun to releasesurroundings Tens of thousands larva of Yellow fever mosquito (Aedes aegypti) Genetically modified versus Lethal gene A large population that has stabilized in this area of the United States.These ones insect Actually I was originally from Africa Vittori Different and dangerous disease, Come dengue, Zika, Chikungunya Yellow fever is growing with the increase of the local population Resistance Traditional control methods to end or at least contain the threat, so it was decided to pass it onGenetic Engineering. After years of research and arguments between support and opposition, the Federal Environmental Protection Agency (Environmental Protection Agency -Environmental Protection Agency) and Florida Reef Mosquito Control District (FKMCD) gave the green light to the project, and it reached its climax in the first batch of these weeks.
Yellow fever mosquito Genetically modified organisms Created by a British biotech company Iron oxide ore, Engaged in this work for many years.The insects released are male (In the form of a larva) Not stinging once AdultAfter mating, they pass the deadly gene to the female; in short, when a female fertilized by a genetically modified organism will give birth egg, All those who are destined to be women-the only ones who are stinged-will not develop and die because the gene makes them dependent on antibiotic (tetracycline). All females who continue to mate with transgenic males will no longer have infectious offspring, resulting in a decrease in the number of yellow fever mosquitoes (invasive, non-native).Genetically modified mosquitoes will also carry a gene that makes them adults Fluorescent lamp When exposed to specific light, an effective way to control the spread of these silent “killers”.
Aedes aegypti mosquitoes account for about 4% of the total number of mosquitoes in the Keys, but they are actually responsible for all human diseases transmitted by mosquitoes. ” He has announced The Mosquito Control Center emphasized the need to adopt such a severe solution. However, not everyone is in favor of releasing genetically modified organisms into the natural environment. Jaydee Hanson, Director of International Technology Assessment Center and Food Safety Center He has told the Guardian The project is a “Jurassic Park experiment,” and Barry Ray, executive director of the Florida Keys Environmental Alliance, pointed out that “people in Florida do not approve of releasing genetically modified mosquitoes or conducting human experiments.” Given these different positions, the first release It took several years.
The project expects them to be released once a week 12,000 eggs The GMO males total 12 weeks, so in various areas of the Florida Keys, known for their spectacular wetlands, 140,000 GMO mosquitoes. Certain areas will not involve cross-checking the effectiveness of interventions.The ultimate goal is to release Millions of these insectsAims to eliminate the problem of infectious diseases. Since female larvae affected by the mutant gene will survive on tetracycline, Oxitec He has announced The males will be released hundreds of meters away from waste water areas, orchards, commercial areas, etc. All that remains is to wait for the initial results of the controversial experiment to determine whether it is possible to win the battle against yellow fever mosquitoes.
