BRAZIL-MOSQUITO-DENGUE-CONTROL-OPERATION

Brazilian biologist Roberto Costa Peres releases some of 10,000 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-- in Tubiacanga, Ilha do Governador, Rio de Janeiro, on October 2, 2014. The mosquitoes 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.
