More than 100-thousand genetically modified mosquitoes were released in Brazil, in part of an effort to battle the ongoing dengue epidemic.

Oxitec, a global initiative focused on insect control, is responsible for the project in Sao Paulo.

Oxitec scientists inject the male mosquitoes with a modified gene containing a protein known as TTA.

When they produce offspring with the dengue-carrying female, the next generation will die before reaching adult phase.

It claims this method is capable of suppressing the mosquito population in the area by 90-percent.

Oxitec’s leader of field operations says similar results were seen in the Cayman Islands in 2009, and most recently in Panama.
