Native bacteria block Wolbachia from being passed to mosquito progeny

Researchers discovered that a type of bacteria called Asaia blocks invasion of Wolbachia into mosquitoes' germlines, stopping the insects from transmitting Wolbachia to their offspring. This finding provides a potential answer to why some insect species are infected with Wolbachia while others are not.
