Wolbachia induces male-specific mortality in the mosquito Culex pipiens (LIN strain).

<h4>Background</h4>Wolbachia are maternally inherited endosymbionts that infect a diverse range of invertebrates, including insects, arachnids, crustaceans and filarial nematodes. Wolbachia are responsible for causing diverse reproductive alterations in their invertebrate hosts that maxi...
