linda gates foundation and it is interesting because it is cheap and probably quite safe, unlike intech decides which are toxic and need to be continuously respray. wolbachia containing mosquitoes should theoretically be good to go once you release them once. you only need to release them once but there is no genetic modification so it's an easier cells for communities have to reject those approaches. and it seems that wolbachia stops the spread of these viruses through many different groups, through competing with nutrients, stimulating the insects immune system and in many ways. that is reassuring because as carl said, irises have a habit of running rings around us and no sensible evolutionary biologists with assuming that evolution will not get the better of us at some point but if the bacterium allows the insect to resist the viruses or to be a bad inspector for those viruses and have many different types of resistance would theoretically need to evolve which would be hard. so, here we have a really interesting approach that is a solution seeker, who knows but we will wait and see.
