How often are male mosquitoes attracted to humans?

Many mosquito species live close to humans where females feed on human
blood. While male mosquitoes do not feed on blood, it has long been
recognized that males of some species can be attracted to human hosts. To
investigate how commonly male mosquitoes are attracted to humans, we
review existing literature and performed human-baited field trials. We
then undertook further laboratory and tent experiments to examine
attraction to humans in males and females of three
common Aedes species. We find that male attraction to
humans is restricted to a handful of species including Aedes
aegypti and Ae. albopictus. The presence of male
host-seeking behaviour in some species may promote mating success and
contribute to these species being globally invasive. Male and
female Ae. aegypti show similar patterns in
preferential attraction between different human subjects. We also
demonstrate that mosquito repellents applied to human skin repel male
mosquitoes. Our findings provide insights into mosquito evolution and
behaviour and have implications for mosquito control programs,
particularly those that involve monitoring of the male mosquito
population.
