View of Aedes aegypti mosquitoes infected with the Wolbachia bacterium --which reduces mosquito transmitted diseases such as dengue and chikungunya by shortening adult lifespan, affect mosquito reproduction and interfere with pathogen replication-- at the Oswaldo Cruz foundation in Rio de Janeiro, Brazil, on October 2, 2014. The mosquitoes, when released, are expected to quickly infiltrate the insect population and stop the spread of the disease. Small-scale trials have already been conducted in communities in northern Australia.
