Cornell researchers are biting back at deadly mosquito-borne illnesses, using nature’s own tricks.
A team in the College of Human Ecology is a winner in a global competition that asked innovators to create radically sustainable environmental solutions inspired by the natural world. The Cornell team created a mosquito-control device that functions like a carnivorous plant.
The device, dubbed the UPod, was inspired by the carnivorous Utricularia vulgarisor common bladderwort plant, which creates a water vacuum through its trap bladders by pumping water out and sucking in small insect prey in the blink of an eye. The device was created by graduate students Anna Gannett, Joey Sun and Paulina Villacreces, and their adviser, professor Kathleen Gibson, from the Department of Design and Environmental Analysis in the College of Human Ecology.
Similar to how the Utricularia vulgarisplant traps prey, the solar-powered UPod pulls water and larvae into a tightly-sealed water chamber through a trap door that functions through a smart sensor mechanism. Larvae are suffocated in the water chamber, then pumped out as new water and larvae are pulled in.
The UPod is one of eight project winners of the Biomimicry Institute’s Global Design Challenge, an international design competition that invites innovators to learn how to use biomimicry – the process of looking to nature for design inspiration – to develop solutions to climate change.
“In the scoping process of our project development, we identified the expansion of mosquito-borne illnesses as a global human health problem related to climate change,” the team said. “Through our research we were able to find out that most of the mosquito control was in the form of vaccines or costly medicine, insecticides, fumigation, awning screens and others, but realized many people do not have access to these options and that these represent only short-term solutions.”
According to the team, higher average temperatures and increased precipitation due to climate change are contributing to the expanding threat of mosquito-borne diseases like dengue, malaria and chikungunya. Current mosquito-control strategies can be harmful to people and the environment.
The UPod was developed to be an environmentally friendly, self-sustaining, reusable and affordable solution that helps individuals, communities and nations take control of larvae populations and prevent the spread of mosquito-borne diseases.
