Bangladesh is studying the feasibility of applying Sterile Insect Technique (SIT) to control the dengue outbreak. A team of experts from WHO-FAO and IAEA arrived in Dhaka to discuss the feasibility of this technique.


  • What is it? Sterile Insect Technique (SIT) is a 'mosquito fights mosquito technique.' 

  • Working: Under this, radiation sterilised male mosquitoes are released in areas with dengue causing female Aedes aegypti mosquitoes turning them infertile. 

  • Significance: This is an environmentally friendly method to control mosquitoes as no pesticide is used. 

  • Global scenario of usage: This breakthrough technique has been tested successfully at two sites in Guangzhou in China.
