Britain and the United States plan to experiment with 2.4 billion genetically modified mosquitoes


Male mosquitoes, as we all know, don’t bite.So have you ever seen genetically modified mosquitoes that only produce males?2.4 billion genetically modified mosquitoes could soon be introduced in California, foreign media reported.It is believed to be an experiment to control the spread of disease., on March 26, the guardian reported earlier this month, the U.S. environmental protection agency (epa) approved the biotech company Oxitec to expand its biological experiment plan in Florida, allowing its in the central valley of California launched a new pilot project, the project is to allow its up to about 2.4 billion in the 2024 years ago gm mosquitoes to experiment.British biotech company uses mosquitoes to control the spread of disease Oxitec says its genetically modified mosquitoes are all male and therefore do not bite people.Genetically modified male mosquitoes are released as eggs, which are ready to be deployed in a device that “just adds water”, making it very convenient.The genetically modified mosquitoes were developed with a special protein, so that when they are paired with other females, they produce offspring that are also non-biting males.The project specifically targets Aedes aegypti, one of more than 3,500 mosquito species and a dangerous invasive insect that spreads diseases like dengue, Zika, Chikungunya and yellow fever in other countries.By releasing the genetically modified mosquitoes, the company hopes to help control Aedes aegypti mosquitoes in California.According to the California Department of Public Health, the number of such mosquitoes in the area has increased in recent years and they have been found statewide in 21 counties.Although no dangerous disease transmission has been reported in California, officials stress the growing risk of disease transmission from the invasive insects.Rajiv Vedyanan, Oxitec’s Aedes aegypti project manager in the United States, said the mosquitoes were non-native and damaging to the environment, and that the female aedes aegypti was active during the day, making it difficult to use conventional insecticides.Oxitec has introduced the special genetically modified mosquito in Brazil and is conducting a year-long trial in the Florida Keys.The company claims the results are encouraging: “Every single gm mosquito larva is a male,” says Vedianathan.The EPA concluded earlier this month that the test was safe for humans and the environment, but ruled that mosquitoes cannot be released near any source of tetracycline, an antibiotic that acts as an antidote.The regulation also prohibits mosquitoes from being released within 500 meters of wastewater treatment facilities, commercial citrus, apples, pears, nectarines, peach growing areas or commercial livestock production areas such as cattle, poultry and pigs.And all the modified mosquitoes are equipped with a marker gene that allows scientists to distinguish them from wild mosquitoes, and will be monitored regularly to make sure the experiment goes according to plan.Even so, the pilot has met resistance.Critics have called on California regulators to stop the experiment, citing the unpredictability of possible consequences and a lack of transparency in the process.So far, the EPA has received nearly 13,000 objections to the project, most of which were collected by advocacy group Friends of the Earth and the Center for Food Technology and Food Safety.David Perls, food and technology program manager for Friends of the Earth in Florida, said California and Florida should not take risks with experimental biotechnology, adding that the lack of publicly available data from Florida field trials makes it difficult to measure the success of the program.”Nothing in science is 100 percent valid,” Perls said.The public, however, is being asked to trust that Oxitec’s experiment will succeed.How do we know if females are produced?See a report they gave you?”Opponents have also raised questions about the gm mosquitoes’ interactions with tetracycline, an antibiotic used in agriculture that can be found in wastewater and accelerates the development of female mosquitoes.They worry that this complex interaction could lead to new hybrid mosquitoes that are harder to control.In addition, the use of mosquitoes to control the spread of disease is also alarming.In response to the objections, Vaidianathan said regulators had reviewed the experimental data, management had presented its findings at meetings across the country and would release the data to the public after the regulatory process was completed.”We have been following epa guidelines to the letter,” he said.Source: Extreme News
