Modified mosquito releases to fight dengue fever, chikungunya or yellow fever

To date, only one technique based on genetically modified mosquitoes has been developed at an operational level, it is the RIDL technique (release of insects carrying a dominant lethal gene, or release of insects carrying a dominant lethality gene). Male mosquitoes which, unlike females, do not bite, are genetically modified. Their offspring die before reaching adulthood. This technique has received authorization from the US Environmental Protection Agency. Last spring, the private company Oxitec began a trial in Florida consisting in disseminating mosquito eggs Aedes aegypti (known to carry many viruses such as dengue fever, yellow fever, chikungunya and Zika) genetically modified in nature for three months.
