Eucalyptus leaf beetle (Paropsisterna beata)
MPI Biosecurity Response Update, 6 August 2014.
The Eucalyptus leaf beetle (Paropsisterna beata) was detected on few Eucalyptus trees at Whitemans Valley, Upper Hutt in August 2012. It is endemic to Australia. Eucalyptus spp. are the only known hosts.
During July surveillance to determine whether the beetles had spread from the infested site and to determine their location was carried out. The survey within the 0 - 500m zone and 500m – 2km zone used intensive bark and litter searching. No beetles were found throughout the zones.
The ground sprays planned for July were carried out as scheduled. No off target deposition was recorded and the residents are still happy with the way operations and liaison is proceeding.
Further surveillance is planned in February 2015 to confirm the effectiveness of the response. Once the results from this surveillance are known decisions will be made on the extent of further activities.
