Via Channel News Asia, a new way to eradicate dengue? Only time will tell, excerpt from the article :
" KUALA LUMPUR: Malaysia is considering releasing genetically modified mosquitoes designed to combat dengue fever, in a landmark field trial that has come in for criticism from environmentalists.
In the first experiment of its kind in Asia, 2,000-3,000 male Aedes aegypti mosquitoes would be released in two Malaysian states in October or November.
The insects in the study have been engineered so that their offspring quickly die, curbing the growth of the population in a technique researchers hope could eventually eradicate the dengue mosquito altogether.
Females of the Aedes species are responsible for spreading dengue fever, a sometimes deadly illness that has killed 100 people so far this year in Malaysia alone.
The World Health Organisation estimates worldwide infections at 50 million annually. Numbers have grown dramatically in recent decades, due to rapid urbanisation and enhanced mobility that has carried the virus further afield.
The proposal field trial follows a series of lab tests conducted in Malaysia since 2006, and the government is seeking public feedback before moving to the next step.
But environmentalists are not convinced, and are concerned the genetically modified (GM) mosquito could fail to prevent dengue and could also have unintended consequences."
