Brown Marmorated Stink Bug

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).

BMSB preparedness

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.

Proposed amendments to the Biosecurity Act

The Ministry for Primary Industries (MPI) has completed a review of the Biosecurity Act 1993 and is currently consulting on several proposed amendments. Since 2018, KVH has been actively involved in the review process, providing input on behalf of the kiwifruit industry, and it is pleasing to see that this input has been reflected in some of the proposed changes. What are the proposed changes? There are more than 70 proposed changes to the Act which vary in significance to our industry. MPI has grouped these proposals into six topics and provided discussion documents and more detailed regulatory impact assessments for each: System wide issues Funding and compensationBorder and importsReadiness and responseLong-term managementLegislative interfaces These documents can be found on the MPI website here. KVH is drafting a comprehensive submission that will address most of the proposed changes, as each has some bearing on how the biosecurity system will operate in the future, although some of the proposals are much more significant to our sector, particularly those in the sections about funding and compensation, readiness and response, and long-term management. KVH has attended a number of workshops with other members of the primary sector to ensure we understand the major issues and help inform our position on these. Over the next month we will be testing and socialising our position with the kiwifruit industry, including industry forums such as the NZKGI Forum, Industry Advisory Council, and the Technical Forum. We welcome the opportunity for further discussion with growers on these matters and will include this as part of our presentation at the upcoming Zespri Grower Roadshows.

Stink bug awareness building

The annual national Brown Marmorated Stink Bug (BMSB) campaign is underway, increasing awareness with the public of the threat this bug poses and the importance to report any possible finds. This high-risk season there will be a continuation of using successful digital channels, like TVNZ Plus and social media – including targeted Facebook, Instagram, and TikTok ads. Shoppers popping into The Warehouse around the country will also see displays, encouraging surveillance and reporting to protect New Zealand.

Fun Fact

We’ve been at a lot of grower field days over the last few weeks, and it’s been great to see you all. Here is a photo from a Trevelyan’s day that included some much-needed sweet treats! Thanks to the Trevelyan’s team for your support. A reminder we have a spring 2024 biosecurity flyer out now, with tips on protecting your orchard investment and managing biosecurity risk through to pollination. Share this with your teams and also check out recordings from this year’s Biosecurity Symposium now available on our YouTube channel. Remember to report unusual vine symptoms, including new or unexpected Psa-V symptoms of concern, to KVH on 0800 665 825 or by email.
