It says that if a contaminated male fertilizes the eggs
of a female without the bacteria, these eggs do not turn into larvae.
That implies that eggs of a female with the bacteria fertilized by a male that also has the bacteria can develop normally. So, assuming the 60% infection rate applies to male and female mosquitos, 60% of males cannot fertilize the eggs of 40% of females due to the bacteria, or about 25% of male/female combinations are incompatible due to this effect.
