Western Australia (WA) is taking several proactive measures to protect its bee population from Varroa mites, maintaining its status as a Varroa-free region. Here's an overview of the protective strategies in place:
## Surveillance Program
WA has implemented a robust surveillance program to detect and prevent the entry of Varroa mites:
- A network of 40 sentinel hives is strategically placed at key locations across the state, acting as an early warning system for exotic bees and bee parasites[1].
- 34 catch boxes are located in Bunbury, Fremantle, and Geraldton[1].
- Plans are underway to expand the sentinel hive program to monitor additional industrial areas and freight hubs in the Perth metropolitan area[1].
- Floral sweeps using butterfly nets are routinely conducted at Fremantle, Bunbury, and Geraldton ports to monitor for exotic bees and mites[1].
## Biosecurity Measures
Strict biosecurity protocols are in place to prevent the introduction of Varroa mites:
- WA has implemented stringent border quarantine measures to reduce the risk of Varroa mites and other bee pests entering the state[1].
- Bees, bee products (including honey), and beekeeping equipment are not permitted to enter WA without meeting specific import conditions and/or treatments[1][3].
- The Department of Primary Industries and Regional Development (DPIRD) coordinates the surveillance program with support from volunteer beekeepers[1].
## Legal Requirements and Industry Cooperation
To ensure effective monitoring and rapid response:
- All beekeepers in WA, including hobbyists, are legally required to register with DPIRD[1][3].
- Beekeepers are encouraged to regularly check their hives and report any unusual findings immediately to the Exotic Plant Pest hotline[1][3].
## Geographic Advantage
WA's geographic isolation provides a natural barrier against the spread of Varroa mites, giving the state an advantage in maintaining its pest-free status[3][4].
## Confidence in Biosecurity Borders
Dr. Sonya Broughton, WA's chief plant biosecurity officer, expressed high confidence in the state's ability to keep Varroa mites out due to:
- Quarantine border checks
- Post-entry surveillance
- Prohibition of bee or honey material from eastern states[2]
While there are concerns about complacency and preparedness within the industry, authorities remain vigilant. The state's biosecurity measures, combined with its geographic isolation, continue to make Western Australia a safe haven for honeybees, protecting both the local honey industry and the purity of WA honey from the threats posed by Varroa mites.
