GMO mosquitoes to eradicate malaria in Africa

Successful experiment in Djibouti, Kenya thinks about it

05-06-2024 by redazione

Rather than in the vaccine, which inevitably encounters obstacles from the pharmaceutical lobbies and has become mired in the swamps of bureaucracy and endless tests throughout Africa, the future for defeating malaria (and perhaps even eliminating a good part of the mosquitoes, which, although they are creatures of the Lord, even the most convinced animal activists find hard to bear) seems to lie in genetics.
The first experiments, in this sense, are flattering and are about to land in Kenya as well, after having been successful in Djibouti, where also because of the climate and the ‘pit’ in which the city resides, the incidence of malaria was very high and where, a detail not to be underestimated, there are hundreds of foreign soldiers from all over the world in the security forces for the Horn of Africa. Recently tens of thousands of genetically modified laboratory mosquitoes were released in Djibouti in an attempt to stop the spread of an invasive species that transmits malaria.


The male ‘Anopheles stephensi’ mosquitoes, which do not sting humans, were developed by the British biotechnology company Oxitec.
Their special feature is that they are equipped with a gene that kills the female offspring before they reach maturity. As is known, only female anopheles mosquitoes bite and transmit malaria and other viral diseases. This is the first time these mosquitoes have been placed in the environment in East Africa.
Similar technology has been successfully used in Brazil, the Cayman Islands, Panama, and India, according to the US Centres for Disease Control and Prevention (CDC). According to CDC estimates, there are now more than one billion such mosquitoes released worldwide as of 2019.


‘We have created good mosquitoes that do not sting and do not transmit diseases. And when we release these friendly mosquitoes, they seek out and mate with wild-type females,' Grey Frandsen, head of Oxitec, told the BBC. The stephensis species, which arrived years ago from Asia and is more resistant than the African species, is now present in six other African countries: Ethiopia, Somalia, Kenya, Sudan, Nigeria and Ghana.
In Djibouti, the first results are already being seen, and countries still dealing with malaria, such as Kenya, are beginning to think seriously about it.
