Auckland fruit fly detections
11 May 2019

Another Queensland Fruit Fly (QFF) has been found within the current Northcote controlled area, bringing the total to eight over the past three and half months.

Biosecurity New Zealand is stepping up on the ground efforts in the suburb, and will begin placing bait on fruit trees to attract and kill adult flies, in particular females. The current restrictions on the movement of fruit and vegetables remain in place, and trapping and the collection of fallen fruit in some of the controlled area will continue.

While it is concerning there has been another detection, it still doesn’t tell us that there is a breeding population. What it does is raises the potential that QFF remain in the area, albeit at very low levels.

The latest finds will mean an expansion of the B Zone in Northcote; and the establishment of a new A Zone with a radius of 200m around the new detection, along with the associated restrictions on the movement of fruit, vegetables and green waste. The controlled area of 1.5 km will be expanded toward the west from the latest detection.

Teams on the ground will continue removing fallen fruit from backyards in the A zone, and placing bait on fruit trees. The bait is made up of a protein to attract adult fruit flies, and a very low concentration of insecticide to kill the flies. People living in the area will be given at least 24 hours’ notice that bait will be placed in their property and will provided with detailed information about the programme.

Details about the Controlled Area Notice: No fruit and vegetables (other than leafy or root vegetables and cooked, processed, preserved, dried, frozen and canned fruit) can be moved from Zone A of the controlled area. In addition, compost and green waste from gardens cannot be moved out of this Zone.

Residents in the A Zone are asked to avoid composting fruit and vegetables. For disposing of fruit and vegetable waste, they are encouraged to use a sink waste disposal unit if possible or bins provided by Biosecurity New Zealand. These bins will be delivered shortly and residents advised of their location.

For the B Zone – no fruit and vegetables grown in the Zone can be moved out of the controlled area. Produce that has been sourced commercially from outside the area can be moved.

People living in Northcote are urged to check if they are living in the Controlled Area Zones and what this means for them. They can do this on the Biosecurity New Zealand website.

Detailed maps of the controlled areas and a full description of the boundaries, and full information about the rules are also available on the Biosecurity New Zealand website.

Summary of finds: Single male QFF have been found in separate surveillance traps in the Auckland North Shore suburbs of Devonport (one single fly) and Northcote (eight single flies over an extended period of time). Three Facialis flies have been found in Otara.
