British scientists use genetically-modified mosquitoes to fight dengue fever in the Cayman Isles Scientists have released genetically modified mosquitoes in an experiment to fight dengue fever. It is the first time genetically altered mosquitoes have been set loose in the wild, after years of laboratory experiments and hypothetical calculations. But while scientists believe the trial in the Cayman Islands could lead to a breakthrough in stopping the disease, critics argue the mutant mosquitoes might wreak havoc on the environment. ‘Anything that could selectively remove insects transmitting really nasty diseases would be very helpful,’ he said. Dengue is a potentially fatal mosquito-borne disease that can cause fever, muscle and joint pain, and haemorrhagic bleeding. More than 2.5billion people are at risk and the World Health Organization estimates there are at least 50million cases every year. There is no treatment or vaccine. Unlike malaria, which is also spread by mosquitoes, dengue outbreaks are unpredictable and bed nets are of limited use because dengue-spreading mosquitoes also bite during the day. Researchers at Oxitec Limited, an Oxford-based company, created sterile male mosquitoes by manipulating the insects' DNA. Scientists in the Cayman Islands released 3million mutant male mosquitoes to mate with wild female mosquitoes of the same species. That meant they wouldn't be able to produce any offspring and lower the population. Only female mosquitoes bite humans and spread diseases. From May to October, scientists released batches of genetically mutated male mosquitoes in cages three times a week in a 40-acre area. By August, mosquito numbers in that region dropped by 80 per cent compared with a neighboring area where no sterile male mosquitoes were released. Luke Alphey, Oxitec's chief scientific officer, said with such a small area, it would have been very difficult to detect a drop in dengue cases. But their modeling estimates suggested an 80 per cent reduction in mosquitoes should result in fewer dengue infections. For years, scientists have been working to create mutant mosquitoes to fight diseases like malaria and dengue, which they say could stop outbreaks before they start. But, others suspect it could be an environmental nightmare. ‘If we remove an insect like the mosquito from the ecosystem, we don't know what the impact will be,’ said Pete Riley, campaign director of GM Freeze, a British non-profit group that opposes genetic modification. He said mosquito larvae might be food for other species, which could starve if the larvae disappear. Or taking out adult mosquito predators might open up a slot for other insect species to slide in, potentially introducing new diseases. Humans have a patchy track record of interfering with natural ecosystems, Mr Riley said. In the past, such interventions have led to the overpopulation of species including rabbits and deer. ‘Nature often does just fine controlling its problems until we come along and blunder into it.’ Oxitec's Alphey said their genetically modified mosquitoes can't permanently change the ecosystem because they only last for a generation. But to stamp out dengue in endemic areas like Asia and South America, billions of the special-order mosquitoes would likely be needed to stifle their wild counterparts.
