Establishing a base for understanding the threat of the brown marmorated stink bug to plants of value to Māori / E whakarite ana he tūāpapa e mārama ai i ngā kino o te ngārara pīhau parauri ki ngā tipu e whai hua ki te Māori

Abstract

The brown marmorated stink bug (BMSB) Halyomorpha halys (Heteroptera: Pentatomidae) is an invasive pest in North America and Europe that damages many plant species and invades human dwellings. It is regularly intercepted at Aotearoa/New Zealand’s borders but is not yet known to have established. Māori are partners in New Zealand’s biosecurity community and an understanding of the potential impact of any invasive alien species to their interests is essential. The known impacts of BMSB in published literature were reviewed with a focus on Māori plant taonga (valued or treasured plant species) in: (1) Māori commercial enterprises; (2) mara kai (food gardens); and (3) the natural estate. Many fruit and some vegetable species are likely to be affected by BMSB in commercial and non-commercial Māori horticulture but the impact of BMSB on indigenous/native and other taonga plant species in mara kai and the native estate is difficult to evaluate. BMSB poses a serious economic threat to some crop species of commercial value to Māori, as well as threat to some native taonga species. A kaupapa Māori approach examining unpublished mātauranga (knowledge) would considerably broaden this understanding. He ngārara raupatu kaha nei i te tini o ngā tipu, te urutomo noa i te hunga tangata te ngārara nei. Ka kaha haukotingia te ngārara nei e te mana ārai o Aotearoa heoi anō, kāore anō kia whakawhenua i a ia. E mahi tahi ana a Māori rāua ko te hapori marukoiora, anō hoki e mārama ana i te mōrearea o ngā tipu tauiwi - e whai pānga kia rātou. Te Tukanga. I arotake i ngā tuhinga e hāngai ana ki ngā kopuratanga e mōhio nei - e Māori ai te titiro o roto: (1) ngā pākihi Māori (2) ngā māra kai (3) te taiao anō hoki. Te Whakautu. He maha hoki ngā huawhenua me ngā huarākau ka pāngia e te BMSB o roto i ngā pākihi, i ngā ahuone Māori heoi anō, te taea te whakatau i ngā pānga o te BMSB ki te iwi taketake me ōna taonga o roto i ngā māra kai. Te Whakakapinga. Kei tino raru ētahi tipu e whai pānga ki te Māori, ngā tipu taketake anō hoki i te BMSB. Mā te tirohanga Māori e whakawhānui i ngā mōhiotanga.

Trapping for early detection of the brown marmorated stink bug, <i>Halyomorpha halys</i>, in New Zealand

“…This could be addressed with nochoice laboratory trials to clarify future research. The risk of BMSB to New Zealand, including Māori taonga (Teulon et al 2019), is evident and monitoring areas of likely introduction is integral to early detection that informs eradication efforts. A high-level IPM framework would effectively manage multiple pests in multiple production systems (Kogan 1998) and will undoubtedly be the goal for BMSB control in all of New Zealand's major production regions should BMSB become established.…”

“…New Zealand is considered to be suitable for establishment of BMSB (Zhu et al 2012;Fraser et al 2017;Kriticos et al 2017). Incursions of BMSB into New Zealand could significantly damage important primary industries, jeopardise successful integrated pest management (IPM) programmes through the application of additional pesticides, and have severe cultural and commercial impacts on Māori, who have significant economic and cultural interests in both horticultural production and the natural estate (Ballingall & Pambudi 2017;Walker et al 2017;Burne 2019;Teulon et al 2019). A significant upswing in detections of BMSB at the New Zealand border since 2014 means that the probability of stink bug establishment remains moderate to high (Duthie 2012(Duthie , 2015Ormsby 2018;MPI 2019;Vandervoet et al 2019).…”
