Bactrocera facialis fruit fly

We found male facialis fruit flies in surveillance traps in Ōtara, Auckland. Find out more about these flies and what we have been doing.

What's the situation?

Three single male facialis fruit flies were found in separate surveillance traps in Ōtara. The first was detected on 18 February and the most recent was found in a surveillance trap on 5 March, 630 metres to the north of the last find inside the current Zone B.

We have since found no more flies in Ōtara and the Controlled Area Notice has been lifted. This means there are no further restrictions on the movement of fruit and vegetables in Ōtara. Biosecurity New Zealand thanks the residents of Ōtara for their help and co-operation.

The pest is difficult to catch at the border because it can arrive as eggs or tiny larvae concealed inside fruit.

Controlled Area Notice lifted

To manage the fruit flies that have been found, an area of Ōtara, Auckland, was put under a Controlled Area Notice (CAN).

Since we have found no more flies in Ōtara, the CAN has been lifted. This means there are no further restrictions on the movement of fruit and vegetables in Ōtara.

We'll continue with trapping for facialis fruit flies in Ōtara pest using fruit fly traps. In the very unlikely event you find maggots in fruit, or find something you suspect to be a fruit fly, please contact our Pest and Disease hotline 0800 80 99 66.

Information about Export Restriction Zones

We have established an Export Restriction Zone (ERZ) of 5.5km around the area where facialis fruit fly were detected in Ōtara. This means export consignments of facialis fruit fly host material must meet additional requirements to move through the ERZ and be eligible for export.

All facialis fruit fly host material destined for export and travelling through an Export Restriction Zone must be contained in an insect-proofed environment and some additional documentation provided.

We've prepared the following information and guidance about the Export Restriction Zone and transit requirements.

Facialis fruit flies are slightly smaller than a housefly with a black thorax (the part below the head), have yellow areas near the wings, and on the triangular area at the end of the thorax. The abdomen or lower body is orange-brown except for some black markings in the middle and towards the sides. The wings are mostly clear, except for dark veins on the front of the wings. See the "Background" section above for images.

Risk to New Zealand

Facialis fruit fly would jeopardise a horticulture industry worth $5 billion a year in domestic sales and exports.

  • 80% of New Zealand's horticulture crops are susceptible to attack by these fruit flies.
  • Fruits and vegetables they attack become inedible.
  • Any fruit and vegetables would be subject to trade restrictions.

Keeping them out

To keep facialis fruit fly out, New Zealand:

  • imposes tough requirements on imported produce
  • checks passengers, luggage and freight at the border
  • has had a dedicated trapping programme since the 1970s.

The traps are an early-warning system, telling us if flies have arrived so we can eradicate them.
