The Ministry of Agriculture and Forestry (MAF) has no plans to use aerial
operations to eradicate fall webworm in Mount Wellington, MAF's director of
forest biosecurity Peter Thomson said today.
Scientific and technical experts met recently and reviewed data from the 723
traps used to monitor for the presence of fall webworm in and around Mount
Wellington. The traps have not shown any further evidence of fall webworm since
the initial find in April 2003.
"The unanimous advice from the scientific and technical experts was that as
no further fall webworm activity has been detected, there is no need to plan for
aerial operations," Peter Thomson said.
"As a result of decisive actions against the fall webworm, the need for
aerial treatment is not seen as necessary.
"We will continue monitoring the traps over the next 12 months. If any
further moths are trapped the first response will be an intensive ground search
and the deployment of additional traps. Consequent actions to treat the site
will be assessed by the Technical Advisory Group.
"MAF wants to thank the Mount Wellington community for their participation
and support in the effort to ensure that the fall webworm does not establish in
New Zealand," said Peter Thomson.
Mount Wellington residents are reminded that the vegetation control zone and
restrictions are still in place and will remain until further notice. Residents
should call 0800 96 96 96 for more information on these restrictions.
Prior to the discovery of fall webworm in April 2003, this pest had never
been found within New Zealand. The fall webworm could have had a serious impact
on urban, native and commercial trees.
If by June 2005 no further fall webworms are found, MAF will be able to
declare success for the Mount Wellington fall web worm eradication programme.
