Yaya Yaya The mosquito is a formidable and destructive pest. And while it’s known that exhalation of carbon dioxide by its victims acts as a highly compelling invitation to dinner, other smelly signals have been less well documented. Published in The Lancet, Bart Knols’ 1996 research, “On human odor, malaria mosquitoes, and Limburger cheese,” changed that. The entomologist described how Anopheles gambiae, Africa’s most prolific malaria-spreading mosquito, exhibited a keen partiality for biting human feet and ankles. Crucially, the research also showed that these mosquitoes can be attracted to Limburger cheese, a stinky fromage that shares many characteristics with the whiff of human feet, offering potential use as a synthetic bait for traps. Interestingly, Knols is one of the few people to have won an Ig Nobel (for entomology in 2006) and a Nobel Peace Prize (shared in 2005 as part of the International Atomic Energy Agency).
