Ep. 4: Dr. Astri Wayadande: Electropenetrography

Dr. Astri Wayadande is known for her work in our understanding of insect feeding. Using a technique referred to as electrical penetration graph or electropenetrography, sucking insects are integrated into a low-voltage circuit. Upon feeding, the insect completes the circuit and different electrical signal patterns indicate different types of feeding behavior.

Talking Bugs
Interviews with Entomologists from around the World
The field of entomology is incredibly vast, with professionals focusing on viruses vectored by the deadliest animal (mosquitoes), academics studying the mechanisms of freeze tolerance, government researchers tackling insects that could pose biosecurity threats, and forensic entomologists arriving at the crime scene. In this series, learn a bit more about who these entomologists are, what inspired them to get into the field, and discuss some of their most recent research.
