Transmission of deformed wing virus (DWV) through imported semen

Australian beekeepers can import drone bee semen to access overseas genetics for desirable traits like improved honey production or resistance to Varroa mites. However, semen can be infected with bee viruses like Deformed Wing Virus (DWV), which we want to keep out of Australia. This is why any imported semen must pass strict virus testing requirements. DWV is very common in honey bees overseas, which makes it challenging to obtain DWV-free semen to import.

This project will investigate the transmission of DWV from queens to their offspring when inseminated with DWV-infected semen. It will also explore the feasibility of anti-viral treatment of imported semen. This information can be used to develop protocols that assist beekeepers to import drone semen that meet the virus testing requirements and maintain strong bee biosecurity.
