Show Notes

Aotearoa New Zealand’s next biosecurity threat might not arrive by ship or plane — it could already be in the air. In this episode of scigest, scientist and host Ki-Taurangi Bradford speaks with biosecurity scientist Dr Toni Withers about the invisible wind pathway carrying pests across the Tasman. 
Toni explains how moths, butterflies and plant pathogens can travel vast distances on air currents, how new forecasting models are predicting when and where incursions may occur, and how interceptions on offshore platforms help test these predictions. 

The episode also explores the vital role of volunteer citizen scientists and the use of isotope analysis to trace where intercepted insects originate. Blown Away web pages: https://bit.ly/4q65ZT0.

Imagine trying to develop a nutritious fish feed for a very picky eater that is only 5 mm long. That’s the challenge scientists at the Bioeconomy Science Institute Maiangi Taiao are tackling as they work to develop new foods for larval fish. Their research could help reduce reliance on traditional live feeds and support a more resilient aquaculture industry, one of the world’s fastest-growing food production sectors.

Yellow-legged hornets pose a significant threat to honey bee colonies. While New Zealand's biosecurity response efforts are providing reasons for optimism, overseas experience offers important lessons on how colonies, beekeepers and industries adapt when hornets arrive. In this episode of Scigest, scientist and host Andrew Dare speaks to Dr James Sainsbury, who recently completed a research project developing a yellow-legged hornet readiness guide for the apiculture industry. They discuss what we can learn from overseas experience and how this research can support New Zealand’s current biosecurity response. If you think you’ve seen a yellow-legged hornet, take a photo and report it to MPI by calling 0800 80 99 66 or emailing [email protected].

Fungi underpin the health of our ecosystems, yet they're one of the least understood groups of organisms. In this episode of Scigest, host Dr Hilary Ireland sits down with recently retired mycologist Dr Peter Buchanan, whose remarkable 50-year career has helped transform our understanding of Aotearoa New Zealand's fungi.
