“This is a big step and it is very exciting,” said Zhiyong Xi, a medical entomologist at Michigan State University who was not involved in the study. While disease-resistant mosquitoes have been created in the lab previously, this is the first time they have taken root in the field, he said.
Several years ago, researchers found that infecting lab ...
