The Ministry for Primary Industries (MPI) is always looking for pests and diseases that might have arrived from overseas. Finding them early is vital for successful biosecurity responses. The online and interactive Atlas of biosecurity surveillance explains more about the what, where and why of our nation’s surveillance programmes, including fruit flies, one of our industry’s “most unwanted”. There are 13 targeted programmes, focusing on specific pests, diseases and biosecurity risks. You can interact with such tools as surveillance maps, showing locations of trap sites, and see latest data for investigations by MPI teams, by region. General surveillance is also important - that is harnessing those who are out on our orchards, to contribute to gathering and reporting information around the presence of potentially new and unwanted threats. If you’ve seen an unusual pest or disease symptom, make a report by filling in our online form and we will be in touch.

It was international Earth Day on Tuesday and here’s a fitting snippet we saw online - celebrate native species! In the USA, native insects, such as spined soldier bugs, have been shown to consume on of our industry’s most unwanted pests, the Spotted Lanternfly (SLF). In a recent study, researchers discovered that predatory insects, especially spined soldier bugs and praying mantises, effectively reduced SLF populations in a controlled setting. Even better, the insects ate the spotted lanternflies regardless of life stage - promising news in the fight to control these very damaging invasive insects. While biological control (using natural enemies to control a population) is unlikely to work by itself, it is one more tool in the toolbox and may one day lead to a reduced reliance on chemical pesticides.

Last week a grower called to let us know that reporting of a shield bug from his home garden via the Biosecurity New Zealand online reporting form had a reply back to them within 30 minutes with the following message. “Fortunately, the bug spotted is not Brown Marmorated Stink Bug (BMSB) but a local species, the brown shield bug. It is present in Australia and New Zealand. It has a huge host range and though not as common as the green vegetable bug, it is a minor pest of some crops. If you are interested, you can see some further information and images of the bug at this information page put together by Landcare Research/Manaaki Whenua.” It’s great to hear stories of industry using the range of reporting tools available and supporting identification by providing a good set of photos – see the ones taken in this case here.

Growers are reminded to update KVH should the Psa status of your KPIN change from undetected to Psa positive. This allows refresh of industry statistics regarding Psa spread, and supports KVH decisions on the supply of nursery stock, budwood and pollen to new developments and existing Psa undetected blocks. Controls are in place under the Kiwifruit Pathway Management Plan to provide protection against the full range of biosecurity threats to our industry, including Psa-V and effective movement controls disallow plant material at risk of harbouring Psa to move to undetected sites. Growers with Psa undetected sites can source Full Certification plant material through the Kiwifruit Plant Certification Scheme (KPCS) to provide greater confidence of freedom from Psa-V and other biosecurity risks. This provides growers and greenfield developers with the best possible start for their investment. KVH is aware that across time, growers may observe Psa-like symptoms on previously undetected blocks, and reminds growers of their responsibility to confirm any new Psa positive status to KVH. Newer growers, or those less familiar with Psa can contact post-harvest technical teams for help with a visual confirmation or assistance in testing for Psa if needed. If you have developed a new orchard over the last few years, and have noted that Psa is now present, you can contact [email protected] to update your KPIN status. Also, if you are a greenfield developer, you can contact KVH for an ID number so that you can receive nursery plants and budwood for your site. This ongoing collective management of Psa at orchard, regional and national level helps minimise Psa-impacts for all growers.

Controls on the movement of fruit and vegetables in the Auckland North Shore suburb of Birkdale have been lifted after no further evidence of the Oriental fruit fly was found in the area. The decision to end the operation follows seven weeks of intensive fruit fly trapping and inspections of hundreds of kilograms of fruit, with no further detections. Residents and businesses in the affected area are being thanked for their support of the movement controls, keeping an eye out for fruit flies, and safely disposing of fruit in provided bins. The support from the North Shore community has been vital to protect our industry and the wider horticultural sector. National routine surveillance will continue, with New Zealand’s system of nearly 8,000 fruit fly traps spread across the country, set for three exotic fruit fly species of concern: the Queensland fruit fly, Mediterranean fruit fly and Oriental fruit flies. KVH thanks industry personnel from APAC who collaborated with us on fruit fly response activities in Birkdale.

KVH recently linked with Scott Wilson, our new Gisborne regional coordinator, in a visit to reconnect with growers for an update on how vine health in the region is tracking following the impacts of Cyclone Gabrielle. See a set of images from the visit here. Pleasingly, growers are seeing a marked improvement in vine health as they work to address drainage and compaction issues and continue replanting with the more water resilient Bounty rootstock. The visit also allowed an opportunity to attend an orchard soil assessment discussion held by Agrotechnovation who presented on the value of physical soil classification as a tool for growers to uncover and improve issues impacting orchard performance, and particularly for those on silted sites. Growers from kiwifruit, citrus and grape sectors attended, as well as Zespri staff and the local Ministry for Primary Industries (MPI) Farm Advisory contact, providing a chance to further build regional networks and connections. The KVH team also met Gisborne pack-house and nursery contacts who connect with us through biosecurity elements of the Pathway Plan including biosecurity plans and Kiwifruit Plant Certification Scheme accreditations. We acknowledge and thank all those who took time from their busy schedules to meet with the KVH team on their day and share their knowledge and insights.

Biosecurity works – and there’s data to prove it. Prevention pays off and, when applied consistently and properly, protects new areas from incursions. New research published in the Conversation shows that biosecurity policies work to protect the environment and are likely to be cheaper than the cost of control or eradication. Introduced species now cost the global economy an estimated $423 billion annually. This article talks about a century of Antarctic data proving biosecurity policies work. Under the web of agreements governing Antarctica, cargo must be checked for any sign of plants, seeds, insects, and rodents. Visitors must ensure the items they bring are clean. In new research, scientists analysed a century of data on how many species have been introduced to the icy continent and surrounding sub-Antarctic islands. Though there’s little human presence there, many species have been introduced and several have established. But across most sub-Antarctic islands, the rate of introduced species has remained steady, or slowed, after biosecurity policies were introduced, even as more humans arrived. The exception was the Antarctic continent itself, where species introductions are increasing. This is likely due to surging visitor numbers and inconsistent biosecurity efforts between different nations and tourist operators.

The Brown Marmorated Stink Bug (BMSB) is the kiwifruit industry’s second-most unwanted biosecurity threat after fruit flies; and the risk of it entering New Zealand is considered extreme.
The BMSB is able to hitchhike on inanimate objects such as cars and shipping containers. If it were to enter New Zealand it would have no problem establishing due to New Zealand’s highly suitable climate and abundance of host material. Its entry and establishment would result in significant production impacts to many horticultural industries.
The high risk and potential consequence of BMSB have made it a priority for biosecurity readiness activities for both KVH and the Ministry for Primary Industries (MPI).

KVH is working with Zespri, MPI and the wider kiwifruit industry to ensure we are all prepared for BMSB, if it were to arrive and establish here. This includes running regular simulation exercises, hosting workshops, and developing joint workplans for how we would manage an incursion and long term response.
Read the BMSB Readiness Plan (A) for information about how the industry is ready for a New Zealand incursion. Read the BMSB Readiness Plan (B) for information about long term management considerations should BMSB establish in New Zealand.
Read the BMSB kiwifruit growers guide to long-term management. The guide outlines all the things growers should do on-orchard and how to do them when managing BMSB long-term.
In August 2018 the New Zealand horticulture industry welcomed the Environmental Protection Authority’s (EPA) decision allowing the release of a tiny Samurai Wasp into New Zealand, if ever there was an incursion of the BMSB. Read the media release here.
KVH and Zespri have recently designed a useful infographic tool for growers. It encourages growers to cast their eye into a possible future where BMSB has arrived in New Zealand and all response/eradication efforts have failed. What long-term management of the bug might look like on-orchard; factors to consider into future planning; and the times of the year each is most appropriate, is summarised in the infographic here.
