What is it all about?

This project is developing a new biological control option to manage Varroa mite, a major threat to honeybee health and pollination services. Varroa mites are a leading cause of colony losses worldwide and pose significant risks to Australian agriculture through reduced pollination and higher production costs. Current chemical controls are limited by resistance, residues and impacts on bee health.

The research is identifying and optimising naturally occurring fungal strains that can infect and kill Varroa mites without harming honeybees or contaminating bee products. Laboratory and hive based trials are being used to test fungal strains for effectiveness, safety and stability under hive conditions. The project is also developing practical delivery methods, such as treated strips, patties and hive entry materials, to ensure the fungi reach mites effectively in commercial beekeeping systems.

Field trials will assess performance in real hives, including impacts on mite populations, bee health and residues in honey, wax and pollen. Alongside the research, a commercialisation pathway is being developed to support registration and future availability of any effective non chemical Varroa control product identified through the research.

The expected outcome is a safe, sustainable and cost effective Varroa management tool that supports healthy pollinators, reliable crop pollination and long term productivity for horticulture and agriculture.
