[The video opens with the title Apiculture Surveillance Progrqamme – Working to Protect New Zealand Apiculture. Ben Phiri, Senior Advisor, Animal Health, MPI then comes on to screen and speaks to camera. The video follows on with imagery of aspects that are being spoken to including beehives, collecting samples of bees, the laboratory and laboratory procedures. Five people who are involved in the process are interviewed and appear on camera.]
[Ben Phiri, Senior Advisor, Animal Health, MPI]
My name is Ben Phiri and I’m a senior advisor, I’m part of the surveillance team Animal Health here based at Wallaceville Upper Hutt I’m in charge of Apiculture Surveillance.
Apiculture Surveillance has many facets the first one is Asurequality who conduct field work.
The field work includes hive inspection and collection of samples.
My name’s John, I’m an AP2
[John Maynard, AP2 (approved person) Asurequality]
And do contractual work for Asurequality doing the exotic bee disease programme
We’re looking under the hive mat for small hive beetles
And that’s fine
Now, we’ll take a bee sample
A apistan strip or two apistan strips per brood box
They stay in for twenty four hours while the sticky board is underneath, catch the mite fall
So it is important for us to guard against exotic organisms because when for example American foul brood first came in to New Zealand production dropped by about seventy percent
So that’s a huge huge drop and for bees we are not talking just honey production we are also talking about impacting orchards and pollination so it can have devastating effects on the New Zealand economy actually
[Dr Sherly George, Team Manager, PHEL]
I’m Sherly George, Team manager responsible for the laboratory component of the Apiculture Surveillance Programme of MPI
A significant number of beehives from high risk sites as well as from the export sites are checked for exotic pests and diseases
It gives assurance or ongoing assurance to our trading partners that New Zealand is free from listed pests and diseases
Secondly, it serves as an early warning signal
So the samples are collected in the field by the AP2s and sent on to Asurquality where they check the sample quality and also that all the information is correct
They get frozen for forty-eight hours before they’re sent on to us here at the Plant Health and Environment Laboratory where we freeze them ourselves and then begin the testing
[Stacey Lamont, Senior Technician, PHEL]
My name’s Stacey Lamont and I’m a senior technician at the Plant Health and Environment Laboratory and I’m responsible for the bee lab technicians as part of the programme
So after the staff have completed all their training we are confident that they are able to identify all of the targeted organisms
So we make sure we emphasise the importance of sample integrity when we are training the staff
Yeah upon completing the training they realise this a key part of the work that we do
So there are six different organisms specifically targeted in the programme including the tracheal mite Acarapis woodii and the small hive beetle Aethina tumida
[Euvarroa spp. Tropilaelaps spp. Varroa jocobsonii Braula coeca Acarapis woodii Aethena tumida]
And we are also on the lookout for other exotic bee species as well
[Wendy Blount Bee Technician]
I’m Wendy Blount I’m a bee technician here and my role is to process and screen samples of adult bees and sticky boards which arrive at our laboratory
We’re looking for targeted exotic organisms
We don’t include Varroa destructor we do make note of it’s occurence and numbers
So we complete three different tests for each sample
We wash the whole bees to dislodge any external arthropods which might be present
We also examine sticky boards which again might collect external arthropods that could be present on the bees
And then we take a section of the whole bee which contains the bee trachea and then we process those sections and examine them to look for the tracheal mite
MPI laboratory has excellent quality systems in place to pinpoint any point of incursion which provides us with the opportunity to act immediately
Different parts of MPI work together with Asurequality as well as with the beekeepers to have a robust system in place to safeguard our apiculture industry

International Year of Plant Health (1.04)
I am life.
I am home to millions.
And I sustain millions more.
My abundance brings prosperity, while my scarcity can be deadly.
I cover much of the earth, and my influence extends far beyond.
I have been around for longer than you can imagine.
But my world is threatened.
People need to take notice.
And do more to secure my future.
Because I am worth protecting.
Your health relies on my health.
Your life relies on mine.
I am plants. I am life.

Science at work: protecting plant health (6.15)
[The video begins with an image of the sun rising behind some trees. The Biosecurity New Zealand logo shows in the lower left corner of the screen. Words appear that say ‘Science at work. Protecting plant health’. An image of a brown marmorated stink bug appears next to the words. During the video, scenes are shown that relate to the words being spoken. This includes footage of kiwifruit and avocado orchards, forests, market gardens, and at outdoor locations like suburban homes where biosecurity staff are checking trees for insect pests. Other scenes during the video show staff at work in laboratories and scientists working at their computers. Also shown is the Post Entry Quarantine glasshouse facility and a detector dog at work. Some of the film shows close ups of the pests under a microscope, of staff doing diagnostic tests and staff being trained in the lab]

[Dr Brett Alexander, Team manager, Plant Health and Environment Laboratory]: The plant kingdom is at the centre of life on earth.
And you don’t need to look very far to understand just how vital plant life is to our own existence and wellbeing. We know this …
But… It is easy to take it for granted that forests, ecosystems and farming practices that have existed through the ages, will continue as they always have. The reality is that exotic pests and diseases threaten these systems. Some could have destructive outcomes in very short order.
In a nutshell, biosecurity is simply this, to be aware of any potential threats and to guard against them.
Inside that nutshell, there is a world of complexity. A myriad of pests and diseases from around the world that can completely overwhelm host plants when they land in a new ecosystem that has had no opportunity to develop defences.
[The video shows Xyllela fastidiosa damage in olive trees, Italy]
Bacteria that can decimate industries, viruses that can make produce inedible, insects that can destroy harvests, and invasive plants that can smother ecosystems.
New Zealand has a strong biosecurity system. We consider ourselves a team of 5 million people watching out for these pests and diseases.
At its heart is our National Plant Protection Organisation - The Ministry for Primary Industries’ and its Plant Health and Environment Laboratory.
We’d like to invite you to come inside for a look at our laboratory. Responding to any biosecurity threat is based on knowing exactly what organism you are dealing with.
Our diagnostic work relies on expertise in all aspects of plant health. It requires tools and techniques from the straightforward to the highly advanced.
A lot of samples come through these doors. They come from a wide range of sources, -
from members of the public, growers, MPI’s border staff, investigators and surveillance programmes. These lead to the laboratory running 30 to 40 thousand tests every year
[Title: Post-entry quarantine]
Being able to import new high-value plant varieties is crucial for horticultural industries. The high-level quarantine facility we operate - is what allows that to happen.
As an example of how this works, this strawberry which was imported from the USA will be inspected twice a week for over 16 months.
It will undergo a series of diagnostic tests checking for a long list of regulated pathogens, often using the nucleic acid-based test, the PCR.
These PCR tests compare the genetic code of an organism against a known reference to see if there is a match.
Each test for each pathogen needs to be specifically developed, many of which have been developed and validated in our laboratories.
Let’s use an example to take a look at the strategies, tools and technologies we work with to protect New Zealand from biosecurity threats.
[Title: Brown marmorated stink bug]
One of the world’s most destructive pests – the brown marmorated stink bug, or BMSB for short.
Stink bugs are very effective at hiding themselves in small spaces in luggage or cargo. Detector dogs are equally effective at finding them.
But they need training using the actual bugs and these bugs need to be maintained with absolutely no risk of an escape. We maintain them in our high level quarantine facility.
Next in the link, the Ministry runs a surveillance programme where traps are set up at 50 high-risk sites around the country.
When a suspect is found it is sent into the lab for an urgent identification.
If it’s female it can be dissected to see if it has ever mated or laid eggs. If it had, that would indicate to the team that more intensive action needs to be taken.
Our scientists also apply cutting edge technology to help manage the risk. We are investigating using Genetic markers that will allow us to trace where in the world a stink bug may have come from. This would give valuable insight to the policymakers who manage our borders.
[Title: High throughput sequencing]
High-throughput sequencing is an advanced molecular diagnostic tool. Firstly, the genetic material is extracted from the bug, then it goes through a process that reveals it's genomic sequence.
This is what the scientists use to unravel the hidden genetic information from the BMSB. It takes all these tools to stop pests like the Brown Marmorated Stink Bug before they can take a hold in New Zealand.
High throughput sequencing opens the door for scientists to answer biological questions about fungi, bacteria, viruses and insects that previously could never be answered.
[Title: Working with innovative technology]
As the National Plant Protection Organisation, it is important to be at the forefront of biosecurity science.
That means always looking for opportunities to improve what we do and how we do it. And regularly evaluating new technology and tools and making sure we have the skill to get value from them.
We provide science advice to government, primary industries and the general public. We work together with our counterparts from other countries and research organisations
and regularly provide science training programmes nationally as well as around the Asia Pacific region.
Connecting with such a large community strengthens both our biosecurity capabilities as well as theirs.
Our aim is to understand pests and diseases and have systems in place before they arrive in New Zealand. With preparation, the pathogen, insect or plant can be accurately identified and the action plan to deal with it can be swung into place.
The complexity of this work, the technology, the systems and the expertise, all of this is focused on one simple objective – to protect plants and protect life.

Why plant health?
The theme of the International Year of Plant Health 2020 is ‘Protecting Plants, Protecting Life’. Plants support life on Earth - they produce the air we breathe and the food we eat.
The FAO estimates that up to 40% of global food crops are lost to plant pests and diseases, resulting in more than US$220 billion of lost trade each year. Protecting plant health is crucial for eliminating hunger, reducing poverty, protecting our environment, and boosting social and economic development.
Importance of plant health in New Zealand
New Zealand's isolation means we are home to many unique families of plants, and biosecurity is hugely important to our nation’s wellbeing.
We also acknowledge and promote mātauranga Māori (Māori knowledge) of plant health. Indigenous insights are vital for guiding plant protection and conservation in New Zealand.
