A single male fruit fly was caught in a surveillance trap on Thursday, sparking a large biosecurity response in the area.
Authorities are trying to work out if the fruit fly is a solitary find, or if it is part of an incursion in the area.
More traps are being set up, so there will eventually be 150 traps within 200m of where the fruit fly was found.
Field teams are out in Devonport visiting houses to check fruit trees, gardens and compost bins that could provide a habitat for fruit flies.
Samples will be taken to check for fruit fly contamination.
Legal controls are in place to restrict the movement of certain fruit, vegetables and compost from the suburb.
People in Devonport are being asked to report any suspected sightings of the Queensland fruit fly, or the discovery of insect eggs or larvae inside fruit or vegetables to 0800 80 99 66.
An advertising campaign is underway and leaflets are being distributed around Devonport.
Signs are also being put up on main roads and at the ferry terminal.
Bins are being organised for the area, so people can safely dispose of locally-grown fruit and vegetable waste.
