Wolbachia are intracellular transitional bacteria that control the reproduction of insects via cytoplasmic incompatibility (CI). “Wolbachia-uninfected females will not breed with infected males, which reduces the frequency of uninfected individuals and increases the frequency of Wolbachia-infected insects in a population.” This effect will cause other transitional controlled transformed symbionts to spread within an insect population which expands the frequency. These insects include: Ae. aegypti, Aedes albopictus, and Culex quinquefasciatus. Densovirus is an example of how the spread is transformed through symbionts, occurring in the natural populations of mosquitoes.
