RNAi – making science-informed responses

Genetic modification has been used in Aotearoa New Zealand since the 1970s. It is used in research laboratories and in contained field tests, in some medicines and medical research and as part of science-based courses. This research is strictly controlled – no one can import, develop, field test or release a genetically modified organism without approval from the Environmental Risk Management Authority.

New Zealand’s laws and regulations governing genetic modification are among the most rigorous in the world, and strike a balance between protecting our health and environment and preserving opportunities for all types of production genetically modified and non-genetically modified.

In 2019, Royal Society Te Apārangi published reports on gene editing scenarios and regulations. The expert panel concluded: “It’s time for an overhaul of the regulations. There’s an urgent need for wide discussion and debate about gene editing within and across all New Zealand communities.” The panel also noted, “New Zealand needs to have its own perspective given our unique cultural heritage and environment, and the special challenges we face in maintaining our biodiversity.”

Exploring ideas about genetic modification

Concept cartoons help students consider a range of viewpoints, justify their own ideas, clarify their thinking and consider others’ ideas.

Is there a place for using RNAi in Aotearoa?

The fundamental aim of biotechnology is to solve problems and make useful products. RNA interference (RNAi) – a form of gene technology – has the potential to help with the vexing issue of pest control in Aotearoa. RNAi is being trialled in the United States to assist with varroa mites and in Australia to slow the spread of myrtle rust.

New Zealand’s BioHeritage National Science Challenge, whose mission is to protect and manage biodiversity and biosecurity, recognises that gene technologies may potentially be useful in pest eradication. The BioHeritage Challenge notes that science plays multiple roles in building knowledge, addressing societal issues and concerns and informing policy.

In this activity, students use a variety of resources to consider personal, societal and science perspectives and make a science-informed response to the use of RNAi as a means of pest control.

By the end of this activity, students should be able to:

• use resources to aid understanding of the basic biology that underpins genetic technologies
• use resources to aid understanding of the threats posed by varroa and myrtle rust
• use resources to aid understanding of te ao Māori perspectives regarding gene technologies for pest control
• use resources to aid understanding of public perspectives of the benefits and risks associated with gene technologies
• use concept cartoons to consider aspects of genetic modification and RNAi
• use concept cartoons to justify/position their ideas on the issues
• discuss/create a science-informed response to the potential use of RNAi as a means of pest control.
