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.

Meet the team

Next in our series of team member introductions is Kerry O’Neil, our Monitoring & Compliance Officer. We started this series late last year to share more about the roles we have, and how each of us interact with you, our readers, and growers, in our day-to-day activities. I’ve been with KVH since December 2021 and day-to-day you’ll see me working with various people and groups across the industry to keep raising the bar and improve our biosecurity practices, organising various monitoring programmes, developing protocols, and ensuring compliance standards are met, so that we all continue managing biosecurity risks. I also audit pack-houses, kiwifruit processors, budwood suppliers, and pollen mills, and try to streamline these processes to keep them as quick and easy as possible for you. I quite enjoy helping nurseries wanting to join the Kiwifruit Plant Certification Scheme (KPCS) – especially working on their manuals, and organising sampling, testing, and external auditing. Before joining KVH, I worked at the Tauranga City Council in regulation and compliance, specifically with food and health registrations and alcohol licensing. Outside of work, I find it hard to say no to a round of golf. I travel a lot so next time I’m in your region I’d love to hear any local recommendations.

February grower roadshows

We look forward to seeing you at the upcoming Zespri Grower Roadshows. We’ll be speaking at each location, providing an update on the fruit fly response and industry biosecurity surveillance systems, including recent unusual symptom reports, alongside presentations from Zespri and NZKGI. The roadshows run 17 – 27 February and will all be held in person, with an option to join the Te Puke event online. Register here.

Fun Fact

What am I? This week we have an image for you – can you guess the object? Our industry-led exotic stink bug surveillance system in the Bay of Plenty has kicked off again this year, thanks to industry organisations working alongside us, and as well as the standard sticky pheromone traps that have been used in previous years, some of the sites now also include one of these – an aerodynamic trap. These Brown Marmorated Stink Bug (BMSB) traps are shaped like a windvane which helps the pheromone travel further, attracting more stink bugs to the area. Originally trialled in kiwifruit in Italy through co-funding from the Zespri Biosecurity Innovation portfolio, it was exciting to see this research being implemented last year on a field visit with other members of the BMSB Council, and now we’ve got eight of our own as part of this year’s industry surveillance network at 14 sites – mainly pack-houses - from Mount Maunganui and Te Puke to Te Puna and Katikati. Our surveillance enhances nationwide efforts while raising awareness of stink bugs across the kiwifruit industry and providing practical, tangible monitoring activities. Importantly, it also builds capability within the industry for any stink bug response, whether that be specifically dedicated to kiwifruit or to assist in joint efforts involving other industries. The Ministry for Primary Industries (MPI) oversees the national BMSB surveillance programme, which operates on an entry risk basis, using lure traps and vegetation searches on a fortnightly basis during the high-risk season of September through to the end April each year. Most trapping efforts are concentrated in the main centres, primarily Auckland, Wellington, and Christchurch. Read more about BMSB, including latest detection data, here.
