How are
mosquitos infected with Wolbachia?

Wolbachia can only be transmitted from parent to offspring inside the female's egg. When a male mosquito that carries Wolbachia mates with a female without the bacteria then that female's eggs don't hatch. Wolbachia-infected female mosquitoes, however, produce normal numbers of offspring – which carry Wolbachia.
