Mosquito attraction to human study : Walter Leal has spent decades studying insects, but one question stood out: why are mosquitoes so attracted to humans? His research identified a natural compound called nonanal, produced by humans and birds, that Culex mosquitoes find irresistible.
Leal, a Brazilian chemical ecologist and professor of entomology at the University of California, Davis, even tested the idea on himself before asking others to participate, as per a report.
