"Recently, mosquitoes and mosquito-borne parasites have developed resistance to chemical treatments and antimalarial drugs."
This seems similar to phage therapy, in that the treatment continues to evolve along with the target.
The treatment in the above article is a fungus. "Despite being lethal to mosquitoes, the transgenic Metarhizium fungus is harmless in humans."
Funny that you mention phage therapy as the first person to implement desease-based pest control for bugs was Félix d'Hérelle, better known for having invented phage therapy a few years later.
His biography is definitely worth reading as his life was entertaining to say the least.
