Episode Details

In this episode of Beekeeping Today Podcast, Jeff Ott and Becky Masterman welcome Dr. Dewey Caron for a wide-ranging discussion on Varroa management, beekeeping education, and the evolving work of the Honey Bee Health Coalition.

Dewey shares his journey from academic entomology to a "retirement" filled with teaching, research, and extension work across the Pacific Northwest. Now based in Oregon, he continues to educate beekeepers through presentations, writing, and his monthly Bee Science series on the podcast.

A central focus of the episode is Dewey's work with the Honey Bee Health Coalition (HBHC), which brings together researchers, beekeepers, industry representatives, and regulators to provide science-based, unbiased guidance for honey bee health. Dewey explains how the Coalition's Tools for Varroa Management guide has evolved since its first release in 2014 and is now approaching its ninth edition.

One of the most important updates discussed is a shift in recommended Varroa thresholds. Where beekeepers once tolerated higher mite levels, emerging research and field experience show that even low mite counts—around 1%—can present significant risk due to the viruses Varroa mites vector, including Deformed Wing Virus (DWV) and related pathogens.

The conversation also highlights the Coalition's decision tool, which helps beekeepers navigate treatment options based on their management style, seasonal timing, and colony conditions. Dewey emphasizes that successful Varroa management is not about a single product, but about integrating monitoring, thresholds, and multiple control strategies.

The episode also touches on Dewey's long-running Pacific Northwest colony loss survey, offering insights into overwintering success, beekeeper experience levels, and management practices across the region.

This episode reinforces a key message: effective beekeeping today requires informed, proactive Varroa management grounded in science and adapted to changing conditions.
