You are being down voted because on the surface your argument seems unreasonable. But in a way you could be correct that the remaining mosquitos have an innate immunity against mating with the sterile mosquitos. Just speculating but it is possible that some mosquitos are able to detect a sterile mosquito by the pheromones, or lack of them, that they produce (or through some other hidden mechanism that we don't know). It is not impossible. All sexual organisms are choosy to some degree when it comes to mating. Otherwise the male would not have to court a female. More tests are needed, I say.
