A large mosquito farm is currently under construction in Brazil to combat arboviruses such as dengue, zika and chikungunya. The cost of construction and operation is estimated at 19 million US dollars. The cost of building and running the biofactory is estimated at US$19 million, with the World Mosquito Program and the Institute of Molecular Biology of Paraná each bearing half.
Up to 100 million mosquito eggs are bred weekly in the factory. The hatched mosquitoes become infected with the bacterium Wolbachia infected and released in towns and villages across the country.
76
percent there have been fewer dengue cases in Niterói since the Wolbachia mosquitoes were introduced.

The Wolbachia mosquito reduced dengue cases by 76 percent, chikungunya cases by 56 percent and Zika cases by 37 percent in the Brazilian city of Niterói, according to the World Mosquito Program.
