By trapping and counting adult female mosquitoes searching for blood meals, public health officials in Brazil have a new, effective way to prevent dengue fever cases and to lower costs associated with the illness.

The new system, which uses traps spaced at 300-m intervals, was implemented in 21 cities in the state of Minas Gerais in Brazil from April 2009 to June 2011. By using traps designed to capture mosquitoes most likely to bite and transmit dengue, health officials can monitor high-risk areas more effectively and specifically target their mosquito control efforts. Traditional approaches that measure larvae and pupae and capture adult mosquitoes by aspiration are labor intensive and less effective.
