Bactrocera facialis fruit fly

We found male facialis fruit flies in surveillance traps in Ōtara, Auckland. Find out more about these flies.

Background

Three single male facialis fruit flies were found in separate surveillance traps in Ōtara between 18 February and 5 March 2019.

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.

About the facialis fly

Facialis fruit flies can harm home gardens and horticultural crops, in particular, capsicum and chillies.

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

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.

If you find larvae in fruit or believe you have seen a fruit fly, call 0800 80 99 66.

If you have any enquiries, call 0800 80 99 66.

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.
