Resource requirements for national active surveillance programmes of high impact exotic pests in New Zealand
S. Ganev and M. Braithwaite
ABSTRACT
Organisms that are new to New Zealand are detected every year. These range from benign or saprophytic to significant pests. Currently, detection of exotic organisms relies on a combination of public submissions, reporting from research scientists and limited planned surveillance programmes. With the exception of the fruit fly surveillance programme, the Ministry of Agriculture and Forestry Biosecurity Authority (MAFBA) does not undertake active surveillance programmes for high impact exotic pests of horticulture and agriculture. This is seen as a potentially significant deficiency. The National Plant Pest Reference Laboratory (NPPRL) was commissioned by MAFBA to conduct pilot surveys of twelve high impact exotic pests to determine the resources required to plan, carry out field surveys and conduct laboratory identifications. The surveys were statistically designed to enable early pest detection and hence, maximise the probability of pest eradication. Pest selection was based on pest reputation, biology, epidemiology and the use of various diagnostic techniques to provide a variety of potential scenarios. This paper presents details of the sampling, statistical methods and resources that were used to compile information on active surveillance programmes for each pest.
