Jumping on bed pantyhose

Description:A machine then sorted out each individual chemical, and one called sulcatone was present only in the stockings worn by humans. As Rockefeller University explains, school researchers studied two types of mosquitoes in Rabai, Kenya, whose disparate behavior was first observed in the s. To suss out which odor Or4 was homing in on, the researchers had human volunteers and guinea pigs don pantyhose for 24 hours. But the researchers note that sulcatone alone can't explain the preference; they added sulcatone to guinea pig odor and the brown-bodied mosquitoes showed no increased preference for the odor. They then began a process of cross-breeding and sorting that ultimately allowed them to identify an odor-receptor gene, Or4, that was much more highly expressed in human-preferring mosquitoes.
