He isolated malaria parasites from the salivary glands of mosquitoes that had fed on infected birds. [248] For this work, Ross received the 1902 Nobel Prize in Medicine.
Smells produced by humans are a big part of what draws mosquitoes to us. In a study, scientists helped pinpoint the chemicals in body odor that attract the insects. What mosquitoes are most ...
