With over half the world now at risk from mosquito-transmitted dengue fever, based on the World Health Organization (WHO), the UN is taking the lead on the universal effort to eliminate the disease – and others – by calculating the effect of releasing millions of sterilized pests throughout a number of continents, it announced on Thursday.
Using a process referred to as Sterile and clean Insect Technique (Sit down) – developed years ago to target crop-eating bugs in the United States – UN scientific study has spent the last 10 years adapting it to mosquitoes.

Working with the WHO exotic diseases programme, they have now drawn up guidelines for nations seeking to tackle disease breakouts passed on through the winged bugs.
“Countries have previously began like Italy, Greece and Mauritius, as well as others have the point of accomplishing it, as an example the United States, France and Brazil”, said Jeremy Bouyer, medical entomologist on the Department of Nuclear Techniques in Food and Agriculture, a joint Worldwide Atomic Energy Company (IAEA) / Food and Agriculture Institution (FAO) initiative.
“We currently have proof that Sit down has the capacity to reduce the denseness of mosquitoes really considerably now we should demonstrate that it will likewise impact the transmission in the disease.”
Bug contraception – Explaining the Sterile Bug Technique as “an insect delivery manage method”, Mr. Bouyer explained it entails delivering sterile males “that will out-compete the wild men inside the field and they can cause sterility inside the women so that their eggs will not hatch – which means you will manage the next generation”.
If it is accomplished for long sufficient, “you should be able to reduce, and perhaps, get rid of the target population”, he added.
Working with WHO’s tropical illnesses system, Mr. Bouyer’s team developed guidelines for nations around the world wanting to tackle diseases breakouts passed on by mosquitoes.
Featuring progress in automating and upscaling the mass creation of sterile mosquito communities, which can be released from a drone within their tens of thousands over communities, he additional: “The important bottlenecks that were sexual intercourse working and drone release, are solved therefore we are prepared for pilot testing.”
Dengue, together with other diseases transmitted by mosquitoes – malaria, Zika, chikungunya and yellow high fever – take into account about 17 per cent of all contagious illnesses worldwide, based on the World Health Organization (WHO).
Florence Fouque, Team leader of the UN-subsidized TDR, the Programme for Study and Training in Tropical Illnesses, stated that it might probably consider about 4 years before it is known if the pilot assessments happen to be effective in lessening disease transmission.
“Sometimes surprisingly low population of mosquito can nevertheless transfer diseases, just what exactly we must measure is the influence on the individuals, and this is just what we wish to do as it has never ever been done up to now,” she said.
“Two major varieties of mosquitoes … are transmitting a number of illnesses, which can be infections, such as dengue, zika, chikungunya, yellow high fever; yet it is just about two species, Aedes aegypti and Aedes albopictus.”
Huge potential – If successful, the possible health advantages could be huge, Raman Velayudhan, Coordinator, from WHO’s Division of Neglected Tropical Illnesses (NTDs) said.
Of the current dengue epidemic, he said: “Many countries inside the world have noted a rise, and we have reports from Bangladesh, Brazil, Philippines, and some African nations and almost 10 other Latin American countries, dengue has ongoing to increase.”
Higlighting the safety from the irradiation technique, Mr. Bouyer insisted that no test pipe manufactured genes – known as transgenes – were becoming placed into mosquitoes.
“The mutations we are creating with this program are random, so we are not transgenic, we are not putting transgenes to the mosquitoes and they are happening naturally within the ymtskn population,” he explained. “It’s just that people have sufficient mutations to create complete sterility with what we launch. But there is no specific issue as to what we launch, the mosquitoes are certainly not radioactive, they are just irradiated and therefore sterilized.”
