Washington - Rutgers University’s scientists have discovered a virus responsible for the mass die-off of superworms, which are used as pet food and a human protein source.
Using cryo-electron microscopy, they identified the Zophobas morio black wasting virus, which primarily affects the larvae of darkling beetles, also known as superworms.
Led by researchers Jason Kaelber and Judit Penzes, the study began after beetle farmers reported unexplained deaths in their colonies.
Penzes isolated the virus using virus purification methods, while cryo-electron microscopy revealed the virus as part of the parvovirus family.
The research marks the first time cryo-electron microscopy has been used to discover an unknown pathogen, a breakthrough that could enhance future outbreak management for animals, plants, and humans.
The team is now developing a vaccine using a related virus that doesn't cause symptoms in superworms.
The discovery offers crucial insights for beetle farmers, allowing them to better protect their colonies.
It also demonstrates the potential of cryo-electron microscopy for rapid pathogen detection in future pandemics or agricultural crises.
