What to know about Invasive Species Interaction

Researchers have discovered that Western honey bees in Australia may forage on myrtle rust spores as a nutritious food source. This interaction could facilitate the spread of the invasive fungus via commercial beehive transport and create an ecological feedback loop as native plants are destroyed.

Why it matters

While rust fungi generally rely strictly on wind to spread, researchers discovered that bees may actively forage on the bright yellow fungus spores, packing them into their pollen baskets and carrying them back to the hive just as they would regular pollen.

Common ground

Through a series of experiments, the team made three significant findings.

Claim 1: “Sacchi Shin-Clayton et al, Honey bees as potential vectors of the invasive rust pathogen Austropuccinia psidii: nutritional mutualism and implications for pathogen spread, NeoBiota (2026). DOI: 10.3897/neobiota.106.169027”
VERIFIED
The existence of the study titled 'Honey bees as potential vectors of the invasive rust pathogen Austropuccinia psidii' in NeoBiota is confirmed by multiple web search results, although the specific date 2026 is likely a future-dated publication or typo in the claim, the content and DOI match the research described.

Claim 2: “commercial beehives—regularly transported across the country over three to seven days to pollinate crops—now represent a significant pathway for human-assisted spread of the pathogen.”
