Now that summer’s here, have you noticed that the mosquitoes are out in full force? Did you know that mosquitoes cause more human suffering and disease than any other organism on the planet? Over 750,000 people a year die from mosquito-borne illnesses, and it’s not just humans that are affected! Mosquitoes spread dog heartworms, Eastern equine encephalitis, and many other diseases that affect our pets and local wildlife. But there might soon be a solution!
Researchers have figured out a way to genetically engineer mosquitoes that could dramatically reduce or eliminate some mosquito-borne illnesses. In these mosquitoes, when sperm is produced, the X chromosome that the male would normally pass on to its female young is destroyed, so 95% of the time they only have male offspring. Why does this matter? Well, male mosquitoes don’t bite- the females do. Females spread disease, and one female can lay up to 3,000 eggs over the course of her lifetime.
Hopefully, this type of pest control could eliminate many mosquito-borne illnesses. But could this type of gender control work in other species? Could this research have applications in the understanding and management of X-linked diseases? What do you think?
