A second type of fruit fly (Bactrocera facialis – the facialis fruit fly) was found in the south Auckland suburb of Ōtara.
It is a different species to the
Queensland fruit fly and is a separate incident to that in Devonport.
The facialis is native to Tonga and is known to affect crops of
capsicum and chilli. However, it appears to be less harmful to other fruit and
vegetables.
Ministry for Primary Industries director general Ray Smith said
it was a tropical fruit fly species so New Zealand’s climate may not be an
ideal home for it.
“As with the fruit fly in Devonport, we need to determine
if it’s a lone specimen or if there’s a population of these flies in the
area,” Mr Smith said.
“To do this, we’re setting more traps in the area around
the find.
“And while we look for more flies, we have restricted the
movement of fruit and vegetables to stop the spread of any other facialis fruit
flies that may be out there.
“We are progressively ramping-up activities in the area and
will be working closely with the local community.”
If there are no further detections, the operation is expected to
last two-to-three weeks.
Ōtara under Controlled Area Notice
Parts of Ōtara have now been put under Controlled Area Notice
(CAN).
The movement of certain fruits and
vegetables out of the Controlled Area is restricted to help prevent the spread
of any fruit flies if there are more than one. The CAN is a legal notice.
Those living in Zone A, are not allowed to take out whole fruit or vegetables
(except leafy and root vegetables like taro, lettuce, cabbage, bok choy,
rhubarb, broccoli, brussels sprouts, carrots, parsnips, potatoes, kumara,
celery, onions, spring onions).
Additionally, no fruit or vegetable waste, such as fruit skins
and cores/stones, peelings and the like, or garden waste such as prunings from
fruit trees or vegetable garden cuttings, can go out of the area.
The fruit or vegetables should either be disposed of in a home
in-sink disposal unit or put into specially-supplied Biosecurity New Zealand
bins.
Those in Zone B cannot move home-grown fruit and vegetables out
of the Controlled Area.
Commercially-purchased fruit and vegetables bought at the
supermarket can be moved out of the area. Homegrown produce waste and garden
waste needs to be disposed of in Biosecurity New Zealand bins.
Minister for Biosecurity Damien O’Connor said getting rid of the
fruit fly was New Zealand’s “most well-oiled biosecurity response”.
“We’ve been here several times before and each time we’ve
successfully got rid of this horticultural pest,” he said.
“Two fruit flies is not an incursion as we saw in 2014 when
the fruit fly was found twice in Whangarei, but we can’t be too careful and as
the response ramps up I urge the local community to be vigilant.
“This is a pest that could significantly harm our $5.5
billion horticulture sector and is why the government is committed to do what
it takes to keep it from establishing here.”
This is a pest that could significantly harm the $5.5 billion
horticulture sector.
“Ever more visitors, a changing climate and more trade all
contribute to biosecurity risk and this is the reason we are strengthening the
system, including an extra $10 million at the Budget to bolster our systems
offshore, and why we’re overhauling our 25-year-old Biosecurity Act to make it
fit for the future we face.”
Biosecurity New Zealand has commenced an investigation into how
the fruit flies have entered the country.
The response and eradication of the Queensland fruit fly in
Devonport and the Bactrocera Facialis fruit fly in Ōtara, is estimated to take
two-to-three weeks, both operations costing $1.3 million.
Previous fruit fly responses and successful eradication
include:
- 2016, Tau fly, Manurewa,
Auckland: one fly, level 1 response, two weeks, $1.0m
- 2015, Queensland fruit fly, Grey Lynn,
Auckland: 14 flies and larvae at varying stages, level 2 response (breeding
population), 10-11 months, $16.1m
- 2014, Queensland fruit fly,
Whangarei: one fly, level 1 response, three weeks, $1.1m
- 2014, Queensland fruit fly,
Whangarei: one fly, level 1 response, three weeks, $1.2m
- 2012, Queensland fruit fly, Avondale,
Auckland: one fly, level 1 response, three weeks, $1.5m
If people in the area believe they have seen signs of this fruit fly or found larvae (like white grains of rice) in fruit, they should call the response team on 0800 80 99 66.
