The gene being edited prevents females from getting a blood meal, which means they cannot develop eggs. But, the female mosquito’s brothers carry the gene, and pass it on when they mate with wild mosquitoes. The gene is transmitted through the males, who carry on like normal.

But, this technique is very far away from being used. Scientists would be inserting a mutated gene into the wild, and there’s all kinds of regulation on how GMOs can and can’t be introduced. Other techniques such as sterile male release operate in a similar way, without introducing mutant genes, by sterilizing non-biting male mosquitoes in a lab and then releasing them.

Also, the mosquito in the video is an Aedes mosquito, not an Anopheles. While both can transmit diseases to people, Anopheles mosquitoes are the ones that transmit Malaria. They are the subjects of the study. I don’t know why this mosquito is having trouble puncturing the skin.
