Whangarei Queensland fruit fly Operations update 4
29 January 2014
Note: Updates will be posted at approximately midday daily. Media releases will be issued in the event of significant
developments .
MPI is currently responding to the detection of a single male fruit fly in a surveillance trap last week.
The fruit fly is a significant pest of fruits and some vegetables and poses a threat to both New Zealand’s commercial
growers and home fruit and vegetable gardens.
The Ministry is running an extensive testing programme, examining fruit and vegetable material collected from an area
around the location of the find and setting and examining lure traps to test for the presence of a fruit fly population.
To date, no further fruit flies have been found. Traps taken from Zone B (explanation below) have been examined and no
fruit flies detected.
Field work continues in Whangarei today with personnel inspecting gardens and rubbish bins for any signs of fruit flies
and collecting and re-setting traps to detect any flies present. They are also collecting fruit and vegetables from home
gardens and also from disposal bins for analysis.
There are 83 lure traps in place in Zone A (a 200m circular zone around the find location) and 183 traps in Zone B (a
wider circular zone extending out 1.5km from the find location).
MPI will continue to update results from trap inspections as they come to hand. Traps from throughout the Controlled
Area are being inspected regularly.
The two zones make up a Controlled Area which was put in place on Thursday 23 January with the issuing of a Controlled
Area Notice.
This restricts the movement of fruit and some vegetables out of the specified area.
There are 78 properties within Zone A and 1,401 within Zone B.
The restrictions on the movement of fruit and vegetables will be in place until MPI has sufficient evidence that there
are no Queensland fruit flies present in the area. This will entail traps being checked until they have been clear of
any fruit flies for 14 days. At this stage the controls are likely to be in place until February 8.
The restrictions apply to all movements of whole fruit. Parents of children living in the Controlled Area and sending
their children to school outside the area will need to leave leave whole fresh fruit out of lunchboxes until further
advised. Sliced fruit can be included where by cutting it open, fruit can be seen to be in good condition with no bugs
present in it.
All properties within the entire Controlled Area have been visited and residents provided with full information about
the fruit fly. All these properties have also been inspected for the presence of fruit trees and vegetable gardens with
host plants for the fruit fly.
211 wheelie disposal bins are in place at private homes and key locations throughout the Controlled Area so residents
can dispose of any fruit or vegetables or produce waste. MPI is collecting these, taking some material for analysis and
safely disposing of the material.
A field laboratory is in place examining fruit and vegetable samples collected from within the affected area and will
identify any suspect insects collected.
12 boundary road signs are in place marking the Controlled Area.
Information is being handed out at the Countdown supermarket within the Controlled Area, and customers are being
informed about the movement restrictions on fruit and some vegetables through signs, personal approaches, leaflets and
the in-store PA system.
MPI is in continual contact with other retailers in the area to liaise and ensure that they and their customers are
aware of the restrictions.
There have been no adverse reactions by trading partners to the detection of the single fruit fly.
This find does not constitute an outbreak.
