According to this article from the New York Post, the US just approved the mass release of male mosquitos infected with a bacteria that sterilizes them. The idea, according to the article and some inference, is that they'll mate with female mosquitos and impregnate them with non-viable eggs, causing a missing generation of mosquitos. Brilliant, right?
Well, no. Male mosquitos, from what I can gather, typically live less than a week in their adult phase, mating perhaps once while females will live for a few weeks mating, feeding, laying eggs and repeating until they die. Even if males and females both only manage to mate once, for every female you want to not produce viable young, you'd need to release one infected male. With a very conservative estimate of 10 trillion mosquitos in the United States, one generation per year, and current separation of male from female mosquitos in the lab by hand according to the article, you'd need to manually infect 10 trillion male mosquitos per year, for at least a few years, to make a serious dent in the mosquito population.
How does anyone think this is a practical idea?
