Gene drives offer a potentially revolutionary method for pest control over large spatial extents.

Social support for pest management programs is essential to their success. In this study, we explored stakeholder perceptions of current wasp and what attempting eradication means them. Local stakeholders involved in 7 conservation or projects across Aotearoa New Zealand were interviewed. Q-method analysis identified two major perspectives the participants. A target-driven ambitious perspective emerged where invasive wasps was objective any control method deemed effective could be used achieve that goal. Negative impacts justified by removing larger negative impact on environment. The second agreed must managed but characterised as more holistically minded. Control methods perceived have wider ecosystem less acceptable. Education engagement highlighted increase local future management.
