May 9, 2022 – GMO Mosquito Released in the U.S., they appear to have passed an early test suggesting they could one day help reduce the number of insects that spread infectious diseases.
Scientists free nearly 5 million genetically engineered men as part of testing Aedes aegypti 7-month-old mosquito in the Florida Keys.
Male mosquitoes don’t bite, and these mosquitoes are also engineered so they pass genes on to their female offspring, causing them to die before they can reproduce.In theory, this means that the population Aedes aegypti Mosquitoes die over time, so they can no longer spread disease.
The goal of this pilot project in Florida is to see if these genetically modified male mosquitoes can successfully mate with females in the wild, and to confirm whether their female offspring actually die before they can reproduce.On both counts, the experiment was successful, says Oxitec, the biotech company that developed the engineering Aedes aegypti Mosquitoes, say in one Internet Conference.
More testing in Florida and California
Based on the results of this preliminary study, the U.S. Environmental Protection Agency (EPA) has approved additional pilot programs in Florida and California, the company said in a report. statement.
“Given the growing health threat posed by this mosquito in the United States, we are working to make this technology available and widespread,” Oxitec CEO Greg Franson said in the statement. “These pilot programs, where we can demonstrate the effectiveness of the technology in different climatic settings, will play an important role.”
Initial tests of genetically modified mosquitoes were not designed to determine whether the engineered insects could stop the spread of these diseases. The purpose of the initial tests was just to see how reproduction worked once the transgenic males were released.
The company reports that genetically modified males successfully mate with females in the wild. Scientists collected more than 22,000 eggs laid by these females from traps such as flower pots and trash cans around the community.
In the lab, the researchers confirmed that the offspring of these paired females inherited a lethal gene designed to cause them to die before adulthood. The scientists also found that the lethal gene is passed on to female offspring across generations.
More trials are needed before these genetically modified mosquitoes can be released in the wild on a larger scale—especially since tests done so far have not shown that the engineered bugs can prevent the spread of infectious diseases.
release the transgene Aedes aegypti The introduction of mosquitoes into the wild will not reduce the need for pesticides, as most mosquitoes in the United States are not of this species.
