Pest watch: 2 November 2010 – 21 March 2011 Biosecurity is about managing risks – protecting the New Zealand environment and economy from exotic pests and diseases. The Ministry of Agriculture and Forestry devotes much of its time to ensuring that new organism records come to its attention, to follow up as appropriate. The tables here list new organisms that have become established, new hosts for existing pests and extensions to distribution of existing pests. The information was collated between 26 August and 1 November 2010. The plant information is held in the Plant Pest Information Network (PPIN) database. Wherever possible, common names have been included.
