Importantly, the modified Metarhizium fungus is harmless to humans, despite being so deadly to female mosquitoes. “Interestingly, we noticed that the presence of the fungus did not deter female mosquitoes from mating with infected males. When used with more traditional mosquito control methods, using the modified Metarhizium could be a powerful new tool if it can be brought up to scale. Ledger, the team is working out how best to integrate this new technology with other mosquito control approaches. Using several mosquito control techniques will likely achieve better control than any one approach.
