What Are GMO Mosquitoes and What Is Their Purpose?
17038A. Krosofsky, GREENMATTERS, 2021-05-01 11:29:18.
Scientists have made GMO corn, strawberries, even many types of farm animals. Now, it seems, they have managed to genetically modify mosquitoes as well. But what is the purpose of GMO mosquitoes, and why would scientists go out of their way to create something that is already a problem for a huge portion of the planet’s population? As it turns out, GMO mosquitoes are a way to fight fire with fire. By creating and releasing their own genetically modified mosquitoes into existing populations, a few clever scientists have managed to curb the spread of dangerous mosquito-borne diseases like the Zika virus. According to the CDC, GMO mosquitoes are modified from the Aedes aegypti mosquito species. Aedes aegypti mosquitoes are commonly found in many parts of the U.S., including Florida and Texas. They are well known for spreading and carrying viruses like Zika, dengue, and chikungunya, but the GMO versions of these insects are designed to stop the spread of those diseases right at the source: the carriers themselves.

‘Home to GMO Mosquitoes?!’ Florida Unleashes a Billion Lab Grown Mosquitoes
16925Anonymous, B and T MAGAZINE, 2021-04-30 15:40:06.
Up to a billion genetically engineered mosquitoes are going to be released in the Florida Keys—but locals are having none of it, with billboards erected saying ‘no!’ to the damned blood suckers. The genetically-modified mosquitoes, known as the OX5034, were made in a laboratory in London by British biotech firm Oxitec, in a bid to kill-off a species in the Florida Keys that carries dengue fever, Zika virus, and yellow fever. It comes after more than 7,300 dengue cases were reported in the US in the past decade, Vice reports. While most were contracted outside America, 71 were transmitted in Florida, according to the CDC.
The Release of 1 Billion Exterminator Mosquitoes Has Begun
16922D. Noor, Gizmodo, 2021-04-30 15:32:45.
Tens of thousands of male mosquitoes are descending on the Florida Keys. But these are no ordinary mosquitoes: They’re genetically modified, and they were planted around the state on purpose. It’s part of a plan to curb disease by releasing 1 billion mosquitoes across two states—but it’s giving some folks the heeby jeebies. Workers placed boxes of mosquitoes’ eggs—two on Cudjoe Key, one on Ramrod Key and three on Vaca Key—on Thursday, and expect them to hatch in about a week. They’ll repeat the process over the coming months, releasing 12,000 of the bugs per week for 12 weeks. That’s 144,000 mosquitoes overall—gross. The project marks the first time GMO mosquitoes have ever been released in the U.S., was launched by the Florida Keys Mosquito Control District (FKMCD) with the private British firm biotech Oxitec. It’s an attempt to curb the spread of dengue, Zika and yellow fever.
First-ever US release of genetically modified mosquitoes begins in Florida Keys
16920S. LaMotte, CNN, 2021-04-30 15:27:44.
The first release of genetically modified mosquitoes in the United States began this week in the Florida Keys -- the culmination of a decade-long effort by local mosquito control authorities to see if a genetically modified organism is a viable alternative to spraying insecticides in the region.For the first 12-week phase, blue-and-white boxes containing about 12,000 GMO eggs developed by a US-owned, British-based company called Oxitec have been placed in six small areas of Ramrod Key, Cudjoe Key and Vaca Key. When water is added, the mosquitoes hatch, mature and enter the environment over the next week or so. A small, vocal group of Florida Key residents have fought the release of what they call "mutant mosquitoes" since the project was announced -- and they are incensed. "Our opposition has been long and strong," said Barry Wray, the executive director of the Florida Keys Environmental Coalition. "We live here, this our home, and they're forcing this down people's throats." "The only thing you can do legally at this point is stand in your yard with an insect fogger," said Mara Daly, a resident of Key Largo, Florida, who has fought the release for eight years. "You can't touch a box, but you can fog the s**t out of your own yard if you don't want to be a part of the trial."
Driving genetic destruction
16899Anonymous, Alliance for Natural Health, 2021-04-29 17:41:37.
Genetically-engineered (GE) mosquitoes have been released in a number of countries, including the US. We’ve known for some time that these experiments have not gone to plan, but a new paper provides a better understanding of how they’ve went awry, and provides a harrowing warning for what could go wrong with a new era of gene editing known as “gene drives” in which the genetics of entire species can be tampered with. This could create a nightmare scenario where, instead of a disease-carrying mosquito population being controlled or eliminated, unpredicted changes occur that make them even more virulent and dangerous. Current GE experiments involve altering the genetics of mosquitoes to be “self-limiting,” meaning that offspring inherit a gene that prevents them from surviving to adulthood, thus driving the population down. The goal is to limit the spread of diseases like dengue and yellow fever. But what has happened is that a certain percentage of the offspring of the GE mosquitoes are surviving and integrating into the gene pool of the local population. Scientists note this will have unpredictable consequences and could lead to more pathogenic disease strains—the very opposite of what these experiments were supposed to accomplish.
The first genetically modified mosquitoes released in the U.S. to buzz in the Florida Keys
16897K. Weintraub, USA Today, 2021-04-29 17:37:24.
On Thursday morning, workers from a British company placed basketball-sized cardboard boxes into six yards in the Florida Keys. Then they added water. In a week or so, 12,000 male Aedes aegypti mosquitoes will – one by one – begin buzzing out of each box, the first genetically modified mosquitoes to be released in the United States. Local officials argue the trial is necessary at a time when pesticides are increasingly ineffective against these dangerous pests. A 2016 vote on the project claimed a solid majority of support in most of the surrounding counties. "At the end of the day, our hope is to be able to control this mosquito more efficiently and keep our population below any sort of disease transmission threshold," said Andrea Leal, executive director of the Florida Keys Mosquito District. "Our toolbox for Aedes aegypti control is shrinking, unfortunately, and that's making us think outside of the box."
A Billion Lab-Grown Mosquitos Are Being Released and People Are Freaking Out
16895V. Kipnis, Vice, 2021-04-29 17:08:03.
On Thursday afternoon, six Florida Keys residents will walk out into their yards and set out aquamarine cardboard boxes filled with mosquito larvae. Then, water will be poured into the containers. For the next ten days, as the mosquitoes grow into adults, their neighbors will be waiting to see what happens next. That’s because these aren’t just any mosquitoes: These are genetically-modified organisms, known as the OX5034, and they were made in a laboratory in London. Under a two-year Experimental Use Permit approved by the EPA, the British biotech firm Oxitec has been green-lit to release over 1 billion genetically modified mosquitoes across 6,600 acres in Florida and Texas. For their pilot project, they’re focusing on the lower Florida Keys, where in the coming 12 weeks, they plan to release 144,000 non-biting male mosquitoes from six different locations—making this the first time ever that a genetically-engineered mosquito will be let out into an open ecosystem in the United States.
The mosquito-bite fight begins
16883F. Billingsley, Click2Houston, 2021-04-29 15:10:43.
Anyone who thought February’s freeze would kill all the mosquitos is biting up the wrong leg. They are back and, seemingly so, with a vengeance (did surviving just make them stronger, one wonders?). In Florida this week, an interesting and controversial fight against the bite begins after more than a decade of getting there. The company Oxitec will be releasing 144,000 Genetically Modified Mosquitoes in the Florida Keys designed to fight the mosquito population. Did you ever take the antibiotic tetracycline? I took it to fight acne as a kid but it treats lots of other bacterial infections. Oxitec has engineered all their mosquitoes with a gene that makes only the females depend on tetracycline. Without it, the females die and it’s the females that bite. So all the eggs from the engineered mosquitoes will be shipped to Florida and when they hatch, the engineered female mosquitoes won’t have any tetracycline and they are toast.
Nearly 144K GMO Mosquitoes to be Released in South Florida: What We Know
16902J. Prigeon, 6 South Florida, 2021-04-28 17:46:54.
Nearly 144,000 genetically modified mosquitoes will be released in South Florida this week as part of an effort to reduce the population disease-carrying mosquitoes. The landmark release of GMO insects marks the beginning of the U.S.-approved program to control the number of Aedes aegypti mosquitoes in the area. The project will place boxes loaded with Oxitec’s non-biting male mosquitoes in six areas around the Florida Keys to mate with biting female mosquitoes. As a result of the encounters, the female offspring will not survive and – hopefully – will reduce the dangerous mosquito's population in the area.

GMO mosquitoes to be released in Florida Keys
16880NBC News, WRCBtv, 2021-04-28 15:02:40.
Florida will begin releasing genetically modified mosquitoes this week as part of its efforts to control one of the disease-spreading species of the biting insect. The state will release almost 144,000 nonbiting male mosquitoes in the coming weeks engineered by the British firm Oxitec that are meant to mate with biting females, with any resulting female offspring unable to survive. The project was approved after years of public comment and official review. "As we are seeing development of resistance to some of our current control methods, we are in need of new tools to combat this mosquito," Andrea Leal, executive director of the Florida Keys Mosquito Control District said in a press release. The project is meant to control the population of the Aedes aegypti mosquito, which can spread dengue fever, Zika virus and yellow fever, as well as heartworm to pets and animals.
Nearly 150,000 Gene-Hacked Mosquitoes to Be Unleashed in Florida
16878S. Kim, Newsweek, 2021-04-28 14:58:55.
Nearly 150,000 mosquitoes that have been genetically modified by Oxitec, a biotechnology company based in the U.K., will be released across parts of Monroe County's Florida Keys region starting this week. The release is part of an experiment to help combat a disease-transmitting local mosquito population (the Aedes aegypti mosquito species) that is responsible for "virtually all mosquito-borne diseases transmitted to humans" such as dengue, Zika and yellow fever, the company says. Speaking to Newsweek, a spokesperson for Oxitec said: "We are releasing 12,000 [mosquitoes] per week for 12 weeks," which equates to a total of 144,000 mosquitoes, the spokesperson added. The experiment—a collaboration between the Florida Keys Mosquito Control District (FKMCD) and Oxitec—received approval from the U.S. Environmental Protection Agency (EPA) and the Florida Department of Agriculture and Consumer Services (FDACS). It is also supported by the U.S. Centers for Disease Control and Prevention as well as an independent advisory board, Oxitec says.
Genetically modified mosquito larvae to be released in Florida Keys
16869E. Helmore, The Guardian, 2021-04-28 14:13:40.
The Florida Keys will this week see the release of genetically modified, non-biting male mosquito larvae as part of a controversial program designed to curb the spread of insect-borne diseases such as dengue, Zika and yellow fever. The Florida Keys Mosquito Control District and British firm biotech Oxitec announced last week that 12,000 of the invasive Aedes aegypti mosquito species are expected to emerge each week for twelve weeks from six locations: two on Cudjoe Key, one on Ramrod Key and three on Vaca Key. US researchers seek citizen scientists as billions of Brood X cicadas set to emerge Eventually it is planned that hundreds of millions of the mosquitoes might be released. Oxitec’s non-biting male mosquitoes will mate with the local biting female mosquitoes and since the female offspring cannot themselves survive to reproduce, the population of Aedes aegypti is subsequently controlled. According to the CDC, the genetically modified mosquitoes carry two types of genes: a fluorescent marker gene that glows under a special red light, and a self-limiting gene that prevents female mosquito offspring from surviving to adulthood.
Florida set to release swarms of GMO mosquitoes as residents decry ‘criminal experiment’ by Bill Gates-backed biotech
16866rt com, rt com, 2021-04-28 14:04:30.
A plan to release thousands of genetically modified mosquitoes in an effort to combat disease in the Florida Keys has triggered dire concerns among locals, some saying the “criminal” experiment will turn them into guinea pigs. Spearheaded by the Florida Keys Mosquito Control District (FKMCD) and Oxitec, a British biotech firm that’s received backing from the Bill and Melinda Gates Foundation, the project aims to turn the first swarms of gene-edited bugs loose into the Keys starting sometime this week, the two bodies announced in a joint statement. For the first leg of the plan, set to be expanded later, mosquito boxes will be placed at six locations, which over 12 weeks will release around 144,000 Aedes aegypti mosquitoes, a species most closely linked with transmitting illnesses such as dengue, Zika and yellow fever. If all goes according to plan, the male, non-biting bugs will mate with local biting females, whose female offspring are programmed to die off, helping to control the Aedes aegypti population and reduce the spread of disease. While the particular species makes up only about 4% of the overall population in the Keys, it is behind “virtually all” mosquito-borne diseases passed to humans, as well as some that are transmitted to animals, such as heartworm, according to Oxitec.
BUZZ OFF Florida residents blast pest control ‘TERRORISTS’ over plans to unleash a BILLION mutant mosquitoes in the Keys
16857J. Bentley-York, The SUN, 2021-04-27 20:46:15.
The areas Mosquito Control District (FKMCD) are set to release the gene hacked ‘fraken-squitoes' in a bid to fight insect-borne viruses like yellow fever. A BILLION mutant mosquitoes are set to be released in the Keys to fight insect-borne viruses like yellow fever Florida pest control chiefs have been branded “terrorists” over the plans. The trial is set to begin this week, seeing a first phase of up to 144,000 modified mosquitoes released over the next 12 weeks. The project aims to reduce the numbers of Aedes aegypti species which are known for carrying diseases including dengue, chikungunya, zika and yellow fever. The male mosquitoes, developed by British biotech company Oxitect, do not bite, and will be introduced in small areas in a select number of neighborhoods in the Monroe area. However, Florida residents are calling on the US Environmental Protection Agency (EPA) to end "this live experiment" as they blasted the organisation as “terrorists.” Barry Wray of the Florida Keys Environmental Coalition said: “People here in Florida do not consent to the genetically engineered mosquitoes or to being human experiments.”
Florida to release a billion genetically modified mosquitoes and people are worried
16871B. Robinson, indy100, 2021-04-27 14:19:58.
It sounds like the pitch for a horror movie, but Florida’s about to release up to a billion genetically modified mosquitoes in the Keys. What could go wrong? Florida residents and environmentalists are already voicing their concerns after state officials and Oxitec, a biotechnology a UK-based biotechnology company, announced plans to release the critters over a two year period in Monroe County, in the Florida Keys section of the state. But why? In a press release from Friends of the Earth, they state that the project attempts to reduce the number of Aedes aegypti, one of the many species of mosquitoes that carry infectious diseases such as Yellow Fever and Zika.
Thousands of genetically modified mosquitoes being released in Florida
16863T. Lapin, New York Post, 2021-04-27 13:58:39.
Thousands of genetically modified mosquitoes have begun to be released in Florida this week as part of an effort to combat a disease-spreading species of the insect. The buzzy project, from British biotech company Oxitec, aims to curb the population of Aedes aegypti mosquitoes, which can spread diseases such as Zika and dengue fever, The Miami Herald reported. The project aims to have genetically modified male mosquitoes mate with non-modified females, which are the ones that bite. A so-called “death mechanism” would then act to prevent any resulting female offspring from surviving.
Halt This Nightmare’: Alarm as Florida Set to Begin Release of Genetically Engineered Mosquitoes
16861J. Johnson, Common Dreams, 2021-04-26 20:59:02.
Environmentalists and Florida residents voiced concern and outrage Monday as state government officials and the biotechnology giant Oxitec announced plans to move ahead this week with a pilot project that involves releasing up to a billion genetically engineered mosquitoes in Monroe County over a two-year period. Presented by local authorities as an effort to control the population of Aedes aegypti—a mosquito species that can carry both the dengue and yellow fever virus—critics warn that the effort's supposed benefits and its potential negative consequences have not been sufficiently studied. Responding to news that the first boxes of genetically modified mosquitos are set to be placed in six locations in Monroe County this week, Friends of the Earth noted in a press release that "scientists have raised concerns that GE mosquitoes could create hybrid wild mosquitoes which could worsen the spread of mosquito-borne diseases and could be more resistant to insecticides than the original wild mosquitoes."
Florida residents claim ‘pest control trial’ that will release up to a BILLION genetically engineered mosquitos in the Keys to reduce species carrying diseases is ‘TERRORISM’
16859S. Liberatore, Daily Mail, 2021-04-26 20:54:47.
The Florida Keys will soon be buzzing with close to a billion 'fraken-squitoes' – gene-hacked mosquitoes aimed at eradicating a disease carrying mosquito. The Florida Keys Mosquito Control District (FKMCD) and Oxitec, a British biotech company, are starting the first-ever U.S. release of genetically engineered (GE) Aedes aegypti mosquitoes this week, which will see up to a billion over a two-year period. The project aims to reduce the numbers of Aedes aegypti, one of several mosquito species that can carry diseases including dengue, chikungunya, Zika and yellow fever. Floridians, however, are calling on the US Environmental Protection Agency (EPA) to end 'this live experiment' saying they are being subjected to terrorism by the FKMCD.
Coalition Against GMO Mosquito Condemns Release of Genetically Engineered Mosquitoes
16853GMO Free USA, 3BL CSRwire, 2021-04-26 20:40:26.
Despite a decade of community opposition, the experimental release of genetically engineered mosquitoes begins today in the Florida Keys. British biotech corporation, Oxitec, in collaboration with the Florida Keys Mosquito Control District, plans to release up to a billion genetically engineered mosquitoes in two phases. GMO Free USA and the Coalition Against GMO Mosquitoes condemn the uncontrolled release and are airing radio spots to educate Florida Keys residents about the health and environmental risks. This unprecedented mass release of a genetically engineered insect is the first of its kind in the United States and many Florida Keys residents remain unaware. The Coalition Against GMO Mosquitoes recently launched an educational website, StopGMM.com, and sponsored a local billboard to increase public awareness and galvanize opposition. The new radio spot will run daily on multiple stations. Oxitec and the FKMCD have failed to provide sufficient answers to the most pressing questions posed by concerned residents. Some residents have reached out to government officials at the EPA, in Congress and the White House to request intervention to halt the experiment until thorough research is conducted.
Nation’s First Trial Of Genetically Modified Mosquitoes Starts In Florida Keys
16851N. Klingener, WLRN, 2021-04-26 20:35:50.
Boxes containing the eggs of genetically modified Aedes aegypti mosquitoes, water and a little food are being placed in six locations in the Lower and Middle Keys this week — in a trial that will be the first of its kind in the United States. The genetic modification is intended so that female offspring won't survive. Female mosquitoes are the ones that bite and can transmit diseases like dengue and zika. The genetically modified males are supposed to breed with wild females — and then their female offspring won't survive, either. Andrea Leal is in charge of the Florida Keys Mosquito Control District. The district has been working with the British firm Oxitec for more than a decade, since a 2009-10 outbreak of dengue fever in Key West.
Major fly pest genetically modified in lab to produce more males
16835H. Dunning, Imperial College London, 2021-04-23 14:29:07.
It has been predicted that the world's population will increase to over nine billion people by 2050, and that global food production will need to increase by around 70 percent to match this rate of change. Lead researcher Dr Angela Meccariello, from the Department of Life Sciences at Imperial, said: “Currently, medfly infestations are estimated to contribute towards a loss of up $298 US million annually due to crop damage across a wide geographic area and in over 250 different species of fruits and vegetables. “Due to factors such as climate change, the spread of invasive species and pesticide resistance, there is potential for the negative impact of the medfly on global agriculture to increase if left unchecked. We therefore need new technologies to fight these pests, and our modification could be one such tool.” The team’s modification works by using a DNA-cutting enzyme to destroy the X chromosome during the production of sperm, leading to predominantly male offspring, as females require two Xs. In their experiments, they managed to produce populations of the flies that were 80% male.
Genetically-engineered mosquitoes set for release in Florida Keys: Science offers tool to fight Zika, dengue, malaria but critics claim it’s unnecessary and potentially dangerous
16808J. Musto, Genetic Literacy Project, 2021-04-22 16:02:53.
U.K.-based biotechnology company Oxitec has partnered with the Florida Keys Mosquito Control District in an effort to control the invasive and disease-spreading female Aedes aegypti mosquitoes in the region. Oxitec’s [genetically modified] male mosquitoes — which don’t bite, unlike the recently-discovered yellow fever-carrying Aedes scapularis mosquitoes — will be introduced in small areas in a select number of neighborhoods between mile markers 10 and 93 in the Keys. In recent reporting from Undark, the non-profit digital science magazine notes that Oxitec had been proposing an experimental release in the Keys for years and that it had been rejected before in both Key Haven and Key West — though some residents in surrounding areas voted in support of the release.
CRISPR may help curb malaria by altering a mosquito’s gut genes, new study suggests
16828Cornell Alliance for Science, Genetic Literacy Project, 2021-04-21 16:46:24.
Altering a mosquito’s gut genes to make them spread antimalarial genes to the next generation of their species shows promise as an approach to curb malaria, suggests a preliminary study published in eLife. The study is the latest in a series of steps toward using CRISPR-Cas9 gene-editing technology to make changes in mosquito genes that could reduce their ability to spread malaria. If further studies support this approach, it could provide a new way to reduce illnesses and deaths caused by malaria. Mosquito are becoming increasingly resistance to insecticides and malaria parasites are gaining resistance to antimalarial drugs, creating an urgent need for new ways to fight the disease. Gene drives are being tested as a new approach to controlling mosquitoes, locusts and other insects. They work by creating genetically modified mosquitoes that, when released into the environment, mate with wild insects. The offspring contain genes that either reduce mosquito populations or make the insects less likely to spread the malaria parasite. But scientists must prove that this approach is safe and effective before releasing gene drive mosquitoes into the wild.
Fighting mosquitoes with mosquitoes
16825W. Feng, The Daily Targum, 2021-04-21 16:38:39.
When you think about the animal that has killed the greatest number of humans in the world, you generally tend to think of large predators. Is it perhaps the great white shark or maybe the cute but deadly hippopotamus? While these animals are certainly deadly, the number of annual fatalities caused by them are eclipsed by the number of individuals killed by the tiny blood-sucking mosquito. According to the World Health Organization, approximately 725,000 people are killed every year by mosquito-borne diseases. The mosquito has been the center of numerous pathogenic outbreaks over the last couple decades, such as the West Nile virus, malaria and the Zika virus. While conventional control strategies have been employed, these have all failed to stop the spread of these viruses. To combat this issue, one solution that has been proposed is gene drives. While further testing and research is still required to ensure the safety and efficacy of gene drives, the benefits of this technology far outweigh any potential consequences, lending them to be extremely helpful in the battle against insect-borne diseases.
Eliminating malaria via a simple genetic modification
16822S. Gunn, Front Line Genomics, 2021-04-20 16:32:44.
Despite decades worth of research and efforts, data from 2015 onwards suggests that there has been no significant progress in reducing global malaria cases. Every year, around 400,00 people die from malaria, with over 90% of cases being within sub-Saharan Africa. The rise of mosquito resistance to pesticides as well as malaria parasite resistance to antimalarial drugs has emphasised the urgent need for the development of new tools to fight this disease. One approach that researchers are exploring is the use of gene drives. A gene drive is a genetic modification that can spread through a population at higher inheritance rates than normal. In this context, researchers can genetically modify mosquitos that, when released into the environment, would spread genes to either reduce mosquito populations or make them less likely to spread the malaria parasite. Due to concerns regarding the safety of gene drives, it is vital that researchers prove that this approach is safe and effective before releasing the modified mosquitos into the wild. There are currently no clear pathways for safely testing these tools within endemic countries.
UK biotech firm’s 750 mn GM mosquitoes will mate with females off Florida, sow a deadly gene
16819S. Ramesh, The Print, 2021-04-20 16:27:48.
Oxitec, a UK-based biotechnology company, plans to release genetically modified mosquitoes in the Florida Keys islands off the US this month as part of a trial to curb mosquito-borne diseases like dengue and the one caused by the Zika virus. This is the latest genetic engineering experiment targeting mosquitoes that is aimed at tackling diseases that continue to kill thousands every year — an approach that has critics as well as backers. Only females of mosquitoes bite, while males feed on all nectar. The mosquitoes Oxitec plans to release will all be male, carrying a protein that will kill all their female offspring. The exact locations where the mosquitoes will be released have not been made public. The objective over time is to reduce the population of the Aedes aegypti mosquito, which spreads both the above-mentioned diseases as well as chikungunya and yellow fever. Mosquito populations in Florida are believed to have grown resistant to a common group of insecticides, prompting worries.
This Malaria Preventing Mosquito Is Not A GMO But Is A Science Boost For Nature – Will Activists Want To Block It?
16816H. Campbell, science 2.0, 2021-04-20 16:13:03.
Mosquitoes like Aedes aegypti don't have any value ecologically. If Thanos snapped them out of existence tomorrow there is nothing they do that won't immediately be taken up by 3,000 other mosquito species, not to mention 25,000 bee species when it comes to pollination. The only thing they are great at is killing people; by being a leading source of vector-borne dengue disease. Not far behind is Anopheles gambiae mosquitoes, which carry malaria. Malaria kills nearly as many people each year as COVID-19 did in 2020 but there is no Warp Speed program to keep poor people in developing nations from dying. Environmental activists (overwhelmingly white and wealthy) instead spend $2 billion a year scaring people of color in other countries about science. Pesticides wiped out malaria in the U.S.(1) and remain the best way to go. DDT still works well and is in common use in afflicted countries.(2) Though banned politically in the U.S. half a century ago, our EPA literally writes the manual for how to spray it in homes elsewhere, but the Rachel Carson dream was to replace pesticides with genetically modified crops - optimizing nature to keep other parts of nature from killing everything using fewer chemicals.
Florida to release genetically modified mosquitoes to fight disease
16812K. Jones, WND, 2021-04-17 16:07:26.
A biotechnology company will soon release genetically modified mosquitoes in certain areas of the Florida Keys in order to combat infectious diseases spread by the parasitic insects.The findings could lead to a new method for combating the spread of diseases such as the Zika virus and dengue fever, according to experts. Both diseases are commonly attributed to mosquito bites in humans.Fox News reported that a strain of mosquitoes developed by a United Kingdom-based company called Oxitec -- partnered with the Keys' Mosquito Control District -- will soon be released into a select number of neighborhoods in Florida. The aim of the experimental program is to control the population of the female Aedes aegypti mosquitoes which make life insufferable for many residents of the Keys.

The company says its technology aims to combat dengue fever, a deadly disease transmitted by mosquitoes Aedes aegyptiIn addition to other diseases such as Zika.According to Who is the And the Centers for Disease Control and Prevention in the United States. However, some neighbors are against releasing this transgenic mosquito because they fear that they will become so Guinea pigs. Oxitec Attempts to release genetically modified mosquitoes from 2011But it was always getting delayed due to discussions of places and some scholars. Despite this, the Florida Keys Mosquito Control District agreed to Exam, Which will take place at various locations at Keys.
Breeding Malaria Out: Scientists Engineer Mosquitos to Spread Antimalaria Genes
16800L. Papadopoulos, INTERSTING ENGINEERING, 2021-04-17 13:57:17.
According to the Centers for Disease Control and Prevention (CDC), malaria is a "serious and sometimes fatal disease caused by a parasite that commonly infects a certain type of mosquito which feeds on humans." There are four types of malaria parasites: Plasmodium falciparum, P. vivax, P. ovale, and P. malariae with P. falciparum being the one most likely to result in death. But what if these mosquitos could be genetically altered to spread antimalaria genes instead of the disease? That would be nothing short of a miracle. Researchers from Imperial College London have successfully altered a mosquito’s gut genes to make them spread antimalarial genes to the next generation of their species. This innovation may result in curbing malaria once and for all. This is especially important as the parasite that causes malaria has been becoming increasingly resistant to antimalarial drugs.

16794M. Wehner, BGR, 2021-04-15 13:13:24.
Preventing illnesses in humans is a high priority for scientists that devote their lives to finding cures and techniques that keep people healthy, but sometimes a plan comes along that is so wild it can cause even the most devoted science fans to furrow their brow. In Florida, dengue fever regularly sickens over 100 people per year, and many of those individuals that contracted the virus are believed to have received it locally via mosquitos. Now, in what can only be described as the real-life equivalent of a made-for-TV sci-fi movie, scientists in Florida are prepared to unleash a swarm of genetically modified mosquitoes that will hopefully cut down on the number of the biting insects and, as a result, lower the numbers of mosquito-borne illnesses. The company behind the “OX5034” modified mosquitos is called Oxitec, and while it’s gained approval from the Environmental Protection Agency, there are still plenty of critics that fear unforeseen consequences.
Curbing Malaria’s Spread by Genetic Engineering
16792Anonymous, Genetic Engineering & Biotechnology News, 2021-04-15 13:03:49.
There is an urgent need to find new ways to combat the growing mosquito resistance to pesticides and malaria parasite resistance to antimalarial drugs. Gene drives are being tested as a new approach. In a new study, researchers from the Imperial College London reported that their approach brings gene drives one step closer as a potential strategy for eliminating malaria. Their study was published in the journal eLife, in a paper titled, “Converting endogenous genes of the malaria mosquito into simple non-autonomous gene drives for population replacement.”
New genetic modification could cut malaria spread
16789Staff Writers, MALAYSIA NOW, 2021-04-15 12:56:54.
Altering a mosquito’s gut genes to make them spread antimalarial genes to the next generation of their species shows promise as an approach to curb malaria, suggests a preliminary study published in eLife on Tuesday. The study is the latest in a series of steps being taken toward using CRISPR-Cas9 gene-editing technology to make changes in mosquito genes that could reduce their ability to spread malaria. If further studies support this approach, it could provide a new way to reduce illnesses and deaths caused by malaria. Growing mosquito resistance to pesticides, as well as malaria parasite resistance to antimalarial drugs, has created an urgent need for new ways to fight the disease. Gene drives are being tested as a new approach. They work by creating genetically modified mosquitoes that, when released into the environment, would spread genes that either reduce mosquito populations or make the insects less likely to spread the malaria parasite.
Researchers Using Mutant Mosquitoes To End Malaria, Which Kills 4 Lakh Per Year
16797M. Mohanti, India Times, 2021-04-14 13:20:52.
Every year, more than 22 crore people get infected with malaria and more than 4 lakh die because of it. In fact, in 2019, nearly half of the world's population was at risk of malaria. According to WHO, infants or children aged under 5 years are the most vulnerable group, accounting for two-third of all malaria deaths worldwide. Malaria is caused by parasites that are transmitted to people via the bites of infected female Anopheles mozzies. In a non-immune individual, symptoms--fever, headache, and chills--usually appear 10–15 days after the infective mosquito bite. If it goes untreated for a day, these mild symptoms can progress to severe illness, often leading to death, if bitten by the P. falciparum parasite.
First GMO mosquitoes to be released in the Florida Keys

Oxitec says its technology will combat dengue fever, a potentially life-threatening disease, and other mosquito-borne viruses — such as Zika — mainly transmitted by the Aedes aegypti mosquito. While there have been more than 7,300 dengue cases reported in the United States between 2010 and 2020, a majority are contracted in Asia and the Caribbean, according to the U.S. Centers for Disease Control and Prevention. In Florida, however, there were 41 travel-related cases in 2020, compared with 71 cases that were transmitted locally. Native mosquitoes in Florida are increasingly resistant to the most common form of control — insecticide — and scientists say they need new and better techniques to control the insects and the diseases they carry. “There aren’t any other tools that we have. Mosquito nets don’t work. Vaccines are under development but need to be fully efficacious,” says Michael Bonsall, a mathematical biologist at the University of Oxford, who is not affiliated with Oxitec but has collaborated with the company in the past, and who worked with the World Health Organization to produce a GM mosquito-testing framework.
Transgenic mosquito resistant to multiple serotypes of the dengue virus

The dengue virus causes epidemics in more than 100 tropical and sub-tropical countries, where over 2.5 billion people (over 40% of the world’s population) are currently at risk of dengue infections. In recent years, dengue has become the number one vector-borne disease in Sri Lanka. The worst ever dengue virus outbreaks experienced in 2009, 2010, and 2013 transformed dengue into a major health issue in Sri Lanka. There are no medicines or effective vaccines developed for dengue; therefore, mosquito vector control is the most promising option to control dengue virus transmission. The conventional vector control methods used currently have only limited success. In an attempt to find a solution to this problem, the research team lead by Professor Ranil Dassanayake, Department of Chemistry, University of Colombo in collaboration with Professor Nilmini Gunawardene, Molecular Medicine Unit, Faculty of Medicine, University of Kelaniya undertook to develop a dengue virus resistant transgenic Aedes aegypti mosquito (the primary vector of dengue virus transmission) line using an RNA interference (RNAi) based technology, as a component of the Ph.D. research project of Mr. Kalindu Ramyasoma.
Village hears from experts as genetic-mosquito release experiment nears.
16678J. McCarthy, KEYSWEEKLY, 2021-03-26 14:56:47.
On March 18, Islamorada Village Council heard from several independent scientists who discussed information and issues behind the genetically modified mosquitoes for population and disease suppression. The scientists collectively said they’re neither for nor against the release. A representative from the Florida Keys Mosquito Control District and one from Oxitec responded following the presentation. Fred Gould, professor of North Carolina State’s Department of Entomology and Plant Pathology, briefly explained the strain of mosquitoes (OX5034) set for release. He said he was involved with another strain of genetically modified mosquitoes in development in 2010 when a field case study was conducted in Mexico. “In the laboratory, it turned out the male mosquitoes flew fine and mated well. But in the real environment, they weren’t as strong as the wild type mosquitoes and they basically had 3% of the matings. Instead of having half the matings, they had very few,” he said. Gould went on to say that this is also shown in work by Oxitec in Brazil, where it turns out that the genetic mosquitoes “are not very fit.” “It would take 30 of them, at least, to be equal to an individual wild type in terms of how many matings you have,” he said. “When you’re thinking about that, you have to recognize you have to release a lot of mosquitoes in order to have any activity. I just want to bring that home to you that it goes up and down as to what that percent fitness is, and we don’t know what that’ll look like in Florida. “Will it work? I want to say it might work just fine,” he continued. “There’s a chance that they’ll be doing these releases and it won’t be a simple thing.”
Mosquito anxiety prompts query from congressman
16592T. Java, Keynews.com, 2021-03-10 20:09:26.
Anxiety among some residents over the pending release of hundreds of millions of genetically modified mosquitoes next month in undisclosed locations throughout the Florida Keys has prompted Congressman Carlos Gimenez to seek answers from the U.S. Environmental Protection Agency. The Florida Keys Mosquito Control District and Oxitec, a British-based biotech company, plan to release genetically modified Aedes aegypti mosquitoes in selected neighborhoods between mile markers 10 and 93 as a way to control the wild population of the disease-carrying pest. This is the first experiment of its kind in the U.S.
New Pesticides Will Modify Insect Genes: What Could Go Wrong?
16587Food Tank, EcoWatch, 2021-03-09 19:44:05.
Farmers across the U.S. could soon fill their pesticide spray tanks with a substance known as interfering RNA (RNAi). (RNA is a molecule similar to DNA.) Insects that are exposed to it — either by eating crops sprayed with the substance or by landing on a crop and absorbing it through their bodies — would be genetically modified right there in the field. The pesticide would trigger a process inside the insects' cells to switch off or "silence" genes that are essential for survival — like those needed to make new, healthy cells — thus killing them.
Gene Drives Built to Follow More Stringent Rules of the Road
16590Anonymous, Genetic Engineering & Biotechnology News, 2021-03-08 19:57:32.
Gene drives, or systems that accelerate the spread of desirable genetic traits into a population, may be built to achieve specific levels of spread when released into the wild. By exerting control over the degree of spread, those who unleash gene drives may realize the benefits promised by gene drives—the suppression of disease-carrying or crop-destroying insects—while minimizing the risks that unintended genetic changes could occur that would lead to undesirable ecological outcomes. A gene drive engineered to allow for a high degree of control was recently introduced by scientists based at the University of California, San Diego (UCSD). The new gene drive is a “split drive” system. Details appeared in an article titled, “Inherently confinable split-drive systems in Drosophila.” The article demonstrates that split-drive systems may allow various genetic parameters and strategies to be used to either limit or extend drive potential.
Gene-Editing Approach To Control the Invasive Gray Squirrel
16572M. Campbell, Technology Networks, 2021-03-08 14:33:09.
Biodiversity refers to the extent of the variety of life that is found on planet Earth – and it is currently under threat. Changes in biodiversity have been flagged as "surpassing safe limits" for several years, and world leaders and scientists across the globe are consequently exploring different ways to address the crisis. Invasive species, defined by National Geographic as "an organism that is not indigenous, or native, to a particular area", threaten planet Earth's biodiversity to an even greater extent than climate change. The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) Global Assessment Report found that the number of invasive species per country have risen by ~70% since 1970 across 21 countries that were included in the report. An example of an invasive species is the gray squirrel Sciurus carolinensis found in the UK, which outcompetes the native red squirrel for resources and habitats and carries diseases that are not pathogenic to themselves but can kill red squirrels.
New gene-drive technologies can help control crop pests
16569Anonymous, AZO Life Sciences, 2021-03-08 14:21:28.
The supposed gene drives, which exploit CRISPR technology to affect genetic inheritance, show the potential to quickly spread particular genetic traits across the populations of a specified species. For instance, gene-drive technologies used on insects are being developed to stop the spread of devastating diseases, like dengue and malaria, by inhibiting mosquito hosts from becoming infected. Gene-drives are being designed in agricultural fields to help regulate or remove economically damaging crop pests. But together with the potential to modify populations, there have been concerns about the long-term impacts of these transformative novel technologies in the wild. Both scientists and ethicists have queried about how the so-called gene drives, once turned loose in a regional population, can be controlled if required. Scientists from the University of California San Diego (UC San Diego), Tata Institute for Genetics and Society (TIGS) at UC San Diego, and their collaborators at UC Berkeley have now designed a new technique that gives more control over the release of gene drives. Information about the new “split drive” was published in the Nature Communications and eLife journals on March 5th, 2021.
New ‘Split-drive’ System Puts Scientists in the (Gene) Driver Seat
16555M. Aguilera, UC San Diego News Center, 2021-03-05 19:42:37.
Gene-drive technologies applied in insects, for example, are being designed to halt the spread of devastating diseases such as malaria and dengue by preventing mosquito hosts from becoming infected. In agricultural fields, gene-drives are being developed to help control or eliminate economically damaging crop pests. But along with the capacity to alter populations, concerns have been raised regarding the long-term effects of these transformative new technologies in the wild. Researchers and ethicists have voiced questions about how gene drives, once turned loose in a regional population, could be held in check if necessary. Now, researchers at the University of California San Diego, Tata Institute for Genetics and Society (TIGS) at UC San Diego and their colleagues at UC Berkeley have developed a new method that provides more control over gene drive releases. Details of the new “split drive” are published March 5 in the journals Nature Communications and eLife.
In Uganda, genetically modified mosquitoes bring hope and fear
16550Anonymous, africanews, 2021-03-05 19:32:29.
Scientists here are investigating whether populations of the malaria-carrying insects can be reduced by genetic modification. They're looking at the viability of releasing large numbers of genetically modified mosquitos into the wild to influence future generations. The study is being led by scientists here at the institute in Kampala with researchers from the Target Malaria group. Dr. Jonathan Kayondo is the principal investigator managing the project. He says the disease can be deadly for children, especially those under five-years-old. "The aim here is to develop a new vector control tool for the suppression of malaria transmission," says Dr. Jonathan Kayondo.
Ecology: Gene drives may help control invasive grey squirrel in the UK
16557A. Korn, EurekaAlert, 2021-03-04 19:50:50.
Gene drives introduce genes into a population that have been changed to induce infertility in females, allowing for the control of population size. However, they face technical challenges, such as controlling the spread of altered genes as gene drive individuals mate with wild individuals, and the development of genetic resistance, which may render the gene drive ineffective. To address these challenges, Nicky Faber and colleagues used computer modelling to investigate the effectiveness of a combination of three gene drive technologies using the grey squirrel as a case study.
Genetically modified mosquitoes for better health
16527D. Devis, COSMOS, 2021-03-04 18:24:41.
One method of preventing these mosquito-born diseases is to use insecticides to kill the mozzies and remove them, but sometimes this only works as a short term solution, or has unintended devasting effects on the ecosystem. Another method for decreasing the number of disease-carrying mozzies is to introduce disease resistant, genetically modified mozzies. These transgenic mozzies could be part of a gene drive system where they have a newly introduced disease-resistant gene, linked up with CRISPR mechanisms that help the gene dominate in the population by continuing to copy itself through the genome. All of this requires very thorough risk assessment.
