GENEVA (IDN) – A form of insect birth control – Sterile Insect Technique (SIT) – that sterilises male mosquitoes using radiation will soon be tested as part of global health efforts to control diseases such as dengue, chikungunya and Zika.
The technique involves the mass production, sex-separation and sterilisation of male mosquitoes by exposing them to low doses of radiation. Sterile males released into the wild mate with wild female mosquitoes of the same species, resulting in the production of unviable eggs that lead to a decline in wild mosquito populations.
