The world’s deadliest animal is a picky eater. Because they transmit viral diseases like Zika and chikungunya, and the parasites that cause malaria, mosquitoes like blood-sucking Aedes aegypti are responsible for over 700,000 deaths worldwide every year.
But in Omid Veiseh’s lab at Rice University, his team of bioengineers was struggling to get mosquitoes to eat. Typically, researchers study mosquitoe feeding by letting them bite live animals—lab mice, or grad students and postdocs who offer up their arms for science. That’s not ideal, because lab animals can be expensive and impractical to work with, and their use can raise ethical issues. Student arms don’t scale well for large tests.
In collaboration with entomologists from Tulane
