饮血止渴

Thirsty mosquitoes

Mosquitoes are the world's deadliest animals, transmitting diseases that kill hundreds of thousands of people annually. Only the females bite, to acquire protein to make their eggs. But blood can also serve as a refreshing beverage on a hot, dry day.

A new study finds that dehydrated mosquitoes are more aggressive, land more often on hosts and feed more frequently than those with ready access to water. In quenching their thirst, they may also increase the spread of diseases. The study is by Joshua Benoit, a biologist at the University of Cincinnati and his colleagues. It appeared in the journal Scientific Reports.
