Mosquito antennae could unlock new ways of detecting natural disasters
Monitoring and detecting natural disasters could be improved through a more thorough understanding of mosquito antennae that are being recreated at Purdue University.

Research groups under Purdue professors Pablo Zavattieri and Ximena Bernal conducted this work, which is published in Acta Biomaterialia.
“We’re still in the early stages but we’re pretty optimistic that we’ll at least learn a great deal,” said Zavattieri, the Jerry M. and Lynda T. Engelhardt Professor of Civil Engineering in Purdue’s College of Engineering. “Taking inspiration from nature and using it to advance scientific research has been a core feature of engineering since the very beginning.”
Mosquitoes rely on their antennae to navigate the auditory landscape, homing in on critical sounds amid the background noise of their own wingbeats.
Through analysis of the mosquitoes’ antennal features - particularly the arrangement and morphology of sensory hairs - civil and construction engineering PhD candidate and team researcher Phani Saketh Dasika said they have already gained insights into how these adaptations enhance the auditory sensitivity and selective response to environmental cues.
“Using advanced micro-CT imaging to create high-fidelity CAD models for finite element analysis, we found that the architectural features of mosquito antennae enable species- and sex-specific acoustic target detection, even amid non-target signals like their own wingbeats,” Dasika said in a statement. “Our findings also suggest that mosquito antennae are capable of detecting a broader range of frequencies than previously thought, though not all of these may be actively utilised.”
