Biosecurity quiz answers:

1.    Why is biosecurity important to New Zealand and our primary industries?
Biosecurity is fundamental in protecting New Zealand’s economy, environment and a range of our social and cultural values. It ensures that our unique environment and value of our primary industries are maintained by preventing any unwanted and harmful organisms from entering New Zealand and managing their impacts if they do get here.
2.    Who is the current Minister for Biosecurity?
The Honourable Damien O’Connor

3.    Psa is still an important biosecurity issue for our industry. Name two controls under the National Psa Pest Management Plan designed to prevent further spread of Psa.
-    Reporting any suspicious symptoms to KVH within 48 hours.
-    Having an effective crop protection programme in place.
-    Winter pruning and tying to occur before 1 October each year.
-    Commercially viable kiwifruit is harvested by 1 July each year.
-    Psa positive orchards ensure their orchards are not a significant infection risk to nearby orchards.
-    Controls associated with the movement of risk goods that could transport Psa (e.g. rootstock, budwood, pollen, machinery, bins, beehives etc).

4.    Biosecurity is everyone’s responsibility. What are three important actions that you can do in your role to improve our biosecurity?
-    Promote the importance of biosecurity in your every day practices.
-    Build biosecurity requirements into contracts that you create with staff and service providers.
-    Establish a pest of the month campaign in your workplace to educate staff about potential risks and what to do if anything of concern is found.
-    Ensure that your systems are biosecurity robust.
-    Follow the pathway management plan for Psa.
-    Include biosecurity as a standard item on meeting agendas.
-    Get staff training to manage biosecurity risks on the job.
-    Report the unusual.

5.    Movement of plant material can spread unwanted pests or diseases. Name two biosecurity related actions or considerations when sourcing new rootstock for an orchard.
-    Ensure the nursery is meeting KVH requirements and has Kiwifruit Plant Certification Scheme (KPCS) certification.
-    Consider KPCS certification: “full” vs “restricted”.
-    Consider the areas in which rootstock is moving- i.e. Recovery region to Containment region and whether KVH approval is required.
-    Inspect plants upon arrival before introducing into the orchard.

6.    Travelling overseas is exciting but can lead to the introduction of pests and diseases to New Zealand. To reduce risk, what should you do if visiting a kiwifruit orchard (or other rural areas) overseas before returning home?
-    Declare risk goods on arrival in New Zealand.
-    Clean all clothing and footwear that has been used overseas, paying special attention to plant material, seeds and soil.
-    Where possible, do not bring equipment used on orchards overseas back into New Zealand. If you need too then clean and disinfect/sanitise all equipment.
-    Inform border staff if you have been in rural areas, particularly on orchards.

7.    Imagine you have just imported a tractor from Italy. Name a potential biosecurity risk that could be associated with this import and what can you do to reduce this risk?
Brown Marmorated Stink Bug (BMSB) could be a potential risk from Italy. Ensure import guidelines for these goods are followed according to MPI standards. Check goods on arrival to ensure that nothing has remained on the tractor before allowing it into the orchard. Also accept any other biosecurity risks that could be present either as hitchhikers or on plant material or soil contaminants.

8.    Why is traceability important for biosecurity?
Traceability is an essential component for biosecurity surveillance, response and management.

Tracing where goods have come from and are going to, allows for a rapid understanding of movements when biosecurity threats occur. It assists in understanding and delimiting the spread and helps to determine the best management approach when responding to a threat.  It also provides our trading partners with assurances that the goods they are receiving are safe, and free of pests and diseases.

9.    One of the shield bugs below is a BMSB. The other is a species commonly found in New Zealand. Choose the BMSB and give two reasons for your choice.
The BMSB is on the left. Reasons: larger size (about the size of a 10-cent coin), white banding on the antennae, and alternate markings on the abdomen.

10.    What is this?
It is a BMSB nymph.

11.    This pest is a biosecurity threat to kiwifruit, what is it?
Spotted Lanternfly (Lycorma delicatula)

12.    Not all pathogens can be spread in the wind like Psa, what is another way that pathogens can spread between orchards?
-    On tools/machinery used between orchards
-    With people movements/footwear
-    Animals
-    Grafting of infected material
-    Insect Vectors
-    Rain
-    Through the soil

13.    Name two pathogens not present in New Zealand that are biosecurity threats to our industry?
-    Accept any pathogens that feature on our priority pest list however common examples include:
-    Brazilian Wilt (Ceratocystis fimbriata)
-    Phytophthoras
-    Verticillium Wilt
-    Non-New Zealand Psa strains
