PEST RISK ANALYSIS 4.1 Stage 1: Initiation

4 PEST RISK ANALYSIS

4.1 Stage 1: Initiation

A list of pests likely to be associated with stone fruit from New Zealand (i.e. the biosecurity risk pathway) was generated from information supplied by NZ MAF and literature and database searches. The list was used in this PRA.

The ‘PRA area’ is defined in this pest risk analysis as the State of Western Australia. The ‘endangered area’ is defined as any area within Western Australia where susceptible hosts are present and in which ecological factors favour the establishment of a pest that might be introduced in association with stone fruit from New Zealand. The pathway is considered to be fresh stone fruit for consumption from export orchards in New Zealand.

4.2 Stage 2: Pest Risk Assessment

4.2.1 Pest categorisation

The quarantine pests for stone fruit from New Zealand, determined through this process of pest categorisation, are listed in Table 5. These pests require detailed risk assessment since they meet the IPPC criteria for a quarantine pest, specifically:

• 
  the pest is known to be associated with stone fruit in New Zealand;
  
• 
  the pest is absent from Western Australia, or has a limited distribution and is under official control;
  
• 
  the pest has the potential for being on the pathway;
  
• 
  the pest has the potential for establishment or spread in Western Australia; and
  
• 
  the pest has the potential for consequences.
