Experiments by University of California Riverside entomologists demonstrate mosquitoes are attracted first to carbon dioxide, then to skin odors; findings could lead to more effective mosquito traps The carbon dioxide we exhale and the odors our skins emanate serve as crucial cues to female mosquitoes on the hunt for human hosts to bite and spread diseases such as malaria, dengue and yellow fever. Two entomologists at the University of California, Riverside have now performed...
