The Viagra of Parasites?

Andrew Weeks of the University of Melbourne published a paper in PLoS Biology which used Drosophila simulans to describe the evolution of Wolbachia, a maternally inherited bacteria that causes the host to hatch fewer eggs when uninfected females mate with Wolbachia-carrying males.
