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.

Levy consultation discussions continue

KVH’s consultation on the proposed biosecurity levy increase continues, with growers across the regions taking the opportunity to learn more, ask questions and share their views. Recent meetings have been held in Pukekohe, Waikato, Te Puke, and Gisborne, with constructive discussions focusing on how rebuilding KVH’s biosecurity reserves is essential after five biosecurity responses in the last two years and what it means for growers. See the upcoming meeting schedule here and look out for reminder emails from KVH direct to your inbox. (Unfortunately, our meeting in Motueka last week was affected by weather conditions and cancelled flights, and this has now been rescheduled for Tuesday 11 August). Thank you to everyone who has contributed to the proposal so far.

Win a Prezzy card – have your say on the Pathway Plan review

KVH is reviewing the National Kiwifruit Pathway Management Plan (Pathway Plan) to ensure it remains fit-for-purpose for managing biosecurity risks across the kiwifruit industry. The review will help identify what's working well, where improvements can be made, and which areas should be prioritised for the future. We are seeking feedback from growers, orchard managers, contractors, nursery operators, post-harvest representatives, consultants, and others involved in the kiwifruit industry. The survey takes around five minutes to complete, and everyone who participates can enter a prize draw to win one of two $100 Prezzy cards. Contact details collected for the draw will be kept separate from survey responses and used only for administering the prize draw. Have your say here, by Friday 31 July.
