Brown Marmorated Stink Bug

How to make a submission on the Samurai Wasp application

The Environmental protection Authority (EPA) has called for public submissions on the release of Samurai Wasp, a parasitoid wasp to combat Brown Marmorted Stink Bug. 

Download a copy of TomatoesNZ's submission here.

Submissions are open until Thursday 31 May 2018

Make a submission using this form or this template, or go to the EPA website.

The EPA will also accept emails directly (email: submissions@epa.govt.nz), and require at the minimum only a few sentences of support (if emailing include ‘Application APP203336 ’ in the subject line).

As you are preparing your submission you may wish to consider:

• Providing a description of your business/industry.
• Describing how brown marmorated stink bug has the potential to impact on your livelihood/business/industry (for example, overseas growers have experienced crop losses, aesthetic damage to fruit, management costs, a need to increase insecticide use, labour costs etc)
• Describing how brown marmorated stink bug has the potential to impact on your lifestyle/family/home/garden (for example, overseas people have experienced infested homes and buildings, an unpleasant odour from the bugs etc)
• Describing how brown marmorated stink bug has the potential to impact on your social/cultural/environmental values (for example, overseas BMSB feeds on valued amenity and native plants etc)
• Including whether you feel that the samurai wasp will be a useful BMSB control tool in comparison to the other available tools and why (overseas the primary control methods include insecticide, trapping or exclusion netting)
• Stating whether you wish for the EPA to approve or decline the application.

Tiny wasp to combat stink bug

11 April 2018

Horticultural industry groups along with the Ministry for Primary Industries (MPI) are working together to use a tiny parasitoid wasp to combat the Brown marmorated stink bug (BMSB).

The BMSB Council (a partnership between horticultural industry groups and MPI, under GIA) has made an application to the Environmental Protection Authority (EPA) seeking approval to release the Samurai wasp (Trissolcus japonicus) as a biocontrol agent against BMSB, but only if an incursion is found in New Zealand.

BMSB Council Chair Alan Pollard says if a BMSB incursion is found here, the consequences would be disastrous for New Zealand's horticulture industries and everyday New Zealanders.  

“The stink bug is one of the biggest biosecurity threats we face, and it could cause hundreds of millions of dollars of losses. The wasp provides an opportunity to be proactive in our approach and gives us another tool we can use to control the stink bug,” said Mr Pollard.

“It feeds on over 300 plant species and can multiply and get to very high population numbers rapidly, destroying crops and gardens and even get into your home. In the USA and Europe where the invasive pest has become established, it has caused severe damage to the horticulture industries. It’s also invaded residents’ homes and become a real social nuisance.”

“We’ve also seen growers overseas use high levels of insecticides as the primary way to control the stink bug. We believe the wasp will provide a targeted and self-sustaining control tool and provides growers with another option other than increasing insecticide sprays,” says Mr Pollard.

The wasp does not sting and is harmless to humans but is a natural enemy of the stink bug. The female wasp lays her eggs inside the stink bugs eggs, killing the stink bug in the process. Studies overseas have shown the wasp can destroy over 70 percent of the eggs in a stink bug egg mass.

A NZIER report, commissioned by the Samurai Wasp Steering Group, has estimated that gross domestic product would fall by between $1.8 billion and $3.6b by 2038 if BMSB became established. It also estimated the horticulture export value could fall by between $2b and $4.2b.

Public submissions are now open until 5pm, Thursday, 24 May 2018. Interested parties are encouraged to make a submission on the EPA website.

About the BMSB Council

The BMSB Council is a partnership under GIA between industry and government and is the responsible for BMSB readiness and response. The Council consists of member organisations (Kiwifruit Vine Health, Ministry for Primary Industries, New Zealand Avocado, New Zealand Apples & Pears, New Zealand Winegrowers, Tomatoes New Zealand, Vegetables New Zealand) and observers (Foundation for Arable Research, Horticulture New Zealand, New Zealand Plant Producers Inc., Process Vegetables New Zealand and Summerfruit New Zealand).

About the Government Industry Agreement (GIA)

GIA operates as a partnership between industry groups and Government to manage pests and diseases that could badly damage New Zealand's primary industries, our economy, and our environment. It aims to improve biosecurity outcomes and give everyone the confidence that the best decisions are being made to manage and mitigate biosecurity risks. For more information, visit www.gia.org.nz.

More details about the application can be viewed in this Q&A sheet.

BMSB risk season is upon us

December 2016

The BMSB risk season (summer) is well and truly underway, with MPI reporting as many detections at the border already this season as for the whole of last season.

HortNZ industry is working with MPI, NZWine, Foundation for Arable Research, and better Border Biosecurity (B3) to apply to the EPA for approval of a biocontrol agent for BMSB (Trissolcus japonicus). This work is focused on the EPA approval process so hopefully we can all start to make real progress on the GIA Operational Agreement for response to a BMSB incursion in the new year. 

Read more about BMSB and its biocontrol agent in this article from the February NZ Grower magazine.

Preventing the entry of BMSB remains our key approach but, given the detections, preparing to respond to an incursion is also top of mind.  In the prevention space we appreciate the excellent work done by MPI border staff to detect pests on the cargo, mail and passenger pathways.  The threat from BMSB is increasing as it spreads across Europe.  With an increase in entry pathways keeping alert for BMSB in NZ remains critical so please print out the BMSB posters (below) for staff, friends and family, and report immediately any suspicious bugs!
