So this microbe is already circulating in the mosquito population at a 5% infection rate. The scientists propose either: a) release spores en masse to infect mosquitoes b) infect male mosquitoes in the lab and release them into the wild to infect the females when they have sex There is an obvious third way. We could attempt to genetically engineer a more virulent strain of the pathogen and release it into nature. In the current climate I think this is less than likely to happen.
