Further detections still only hot-spots

Fruit fly larvae brings zone expansion

The recent detection of suspected fruit fly larvae near the eastern boundary of the Greater Devonport Control Area has seen Biosecurity Tasmania expand the overall control area. The larvae was found in fruit on trees in the backyard of a house near a large commercial orchard in the State's north-west.

According to the General Manager of Biosecurity Tasmania, Dr Lloyd Klumpp, the area was already under ground control treatment following the recent detection of two flies on the property.

"Although investigations are ongoing, because of the distance from the Spreyton detection site, it is unlikely we are dealing with a population movement. The information at this stage indicates we have a number of hot spots rather than a spreading population."

Dr Klumpp said there was evidence there may have been problems on mainland Australia in the supply of fruit and Biosecurity Tasmania will be investigating that as part of the traceback investigations.

"Our priority is to identify where these sites are and target them specifically to eradicate fruit fly from the State and re-establish our fruit fly freedom on a state-wide basis."

However, it is not just the island state of Tasmania working to manage this pest.
Recently Victoria's Yarra Valley lost its Pest Free Place of Production following the detection of Queensland fruit fly.

Also this month Western Australian biosecurity authorities banned the movement of host produce in Perth's south following the detection of a female Queensland fruit fly in a suburban trap.

In December Biosecurity South Australia banned the import of Queensland mangoes after one was found to be heavily infested with larvae.
