Female mosquitoes of the species 80s egypti need the nutrients present in your plasma to ensure the proper development of their eggs.

And though their thirst may seem unquenchable, the ladies actually take time to savor your blood once they've sipped their fill. After a female bites, she'll double her body weight,

and then she'll actually completely lose interest in biting people for several days.

Laura Duval, a postdoctoral researcher at the Rockefeller University in New York City. The insect's post-praniel recovery phase made Duval and her colleagues wonder whether they could

essentially trick mosquitoes into thinking they'd already eaten.

Duval works in the lab of Leslie Vosshall, who studies genetics, neuroscience, and behavior.

Here's Vossal.

Our idea was that maybe the same drugs that would turn off human appetite

might actually work to turn off mosquito appetite.

Turns out that when the Rockefeller researchers fed mosquitoes,

a drug that's used to treat people for obesity,

the insects were indeed less interested in hunting for their next human

meal ticket.

But the problem was that we needed to figure out how the human diet drugs were actually working
