From Forest Health News 160, March 2006.
On 20 March the Ministry of Biosecurity New Zealand officially declared the West Auckland and Mt Wellington populations of the painted apple moth (Teia anartoides) eradicated. No moths linked to the original populations had been detected in these areas for 2 years. The moth was first found in Auckland in 1999 and since that time parts of Auckland were aerially sprayed up to 69 times.
The Ministry of Agriculture and Forestry estimated its potential economic impact at between $58 million and $356 million over 20 years if it became widely established, not counting potential impacts on market access or the conservation estate. It cost $62.4 million to eradicate. The trapping and monitoring programme will remain in place for some time. For further details see the MAF website.
