Sterilising Mosquitoes Could Halt Spread of Dengue

As dengue fever remains a deadly threat to lives with increasing number of patients, the Thai Institute of Nuclear Technology has proposed radiology process to sterilise Aedes mosquito, the main carrier of the dengue virus, in the effort to reduce the spread of the carriers. According to health officials, this year saw a dramatic increase of the number of Thai people being afflicted with dengue fever.

They said this was the result of the exponential increase of the number of Aedes mosquito population in the country. The rising concern forced health officials to consider ways to reduce their number. The Thai National Institute of Nuclear Technology has proposed employing radiology as a means of sterilizing mosquitoes which they say will result in a dramatic reduction in their numbers. The experiment was conducted in Nakhon Nayok office of the Institute.

“When these sterilized males are released into the wild and breed with females, the eggs will not have been fertilized and will fail to hatch. This in turn will directly result in a dramatic reduction of the next generation of Aedes mosquitoes,” he said. As we continue to release more of them, each subsequent generation will see their numbers reduced even further. We may even see a complete eradication of the species in some certain areas. He said first trials to release the sterilized mosquitoes will be carried out soon to see if these males can compete with normal male Aedes mosquitoes to breed in the wild.

The success ratio can then be determined so that the correct numbers to be released in a particular area can be specified. The scientists say that the trials should be completed within 2 – 3 months. These sterilized mosquitoes will be released into critical areas in the country to help curb the spread of dengue fever and other mosquito related diseases, he added.
