Using Wolbachia Bacteria to Control Mosquito-Borne Disease

This publication is intended for both the general public and mosquito control professionals. It outlines the use of the bacterium Wolbachia pipientis as a tool to control mosquito populations and reduce the spread of mosquito-borne disease. Biting mosquitoes transmit many pathogens that cause deadly diseases in people, our pets, and our livestock. Collectively, malaria, dengue, West Nile, filariasis, and other mosquito-borne diseases result in millions of infections and hundreds of thousands of deaths every year. Effective vaccines for most of these have not been developed or are not yet available to the general public, and disease management is focused on controlling mosquito populations. Insecticides have become less effective over the past fifty years as mosquito populations all over the world have developed resistance. This has driven scientists to explore new options for controlling mosquitoes, including using the bacterium Wolbachia pipientis.
