Bee Science: Varroa Mites with Dewey Caron (BSD-3)

Release Date: 03/18/2026

Queen Biology and Quality with Dr. David Tarpy (382)

Beekeeping Today Podcast

In this episode, Jeff Ott and Becky Masterman launch a new series focused on honey bee queens with leading researcher Dr. David Tarpy. From the start, the conversation challenges a common oversimplification: the queen is not just an “egg-laying machine,” but part of a dynamic, cooperative system shaped by both biology and worker perception. Tarpy explains that queen quality extends beyond visible traits like brood pattern. Instead, it includes physical characteristics such as body size, mating success, and sperm viability—factors that set the upper limit, or “ceiling,” of colony...

Bee Swarmed with Mateo Kaiser (381)

Beekeeping Today Podcast

Mateo Kaiser joins Jeff and Becky to discuss how Bee Swarmed is changing the way beekeepers find and collect swarms. Built to connect the public with local beekeepers quickly, the platform helps remove the chaos that often surrounds swarm calls and replaces it with real-time alerts, cleaner communication, and better outcomes for both bees and beekeepers. The conversation begins with a timely Hive IQ question about swarm prevention and colony expansion. Jeff and Becky talk through the challenge of managing strong spring colonies, when to divide, and why waiting too long can cost both bees and...

2026 Midwest Honey Bee Expo – Part 3

Beekeeping Today Podcast

Honey show judging and beekeeper education take center stage in this final installment from the 2026 Midwest Honey Bee Expo. In this Beekeeping Today Podcast Short, Jeff Ott and Becky Masterman bring together conversations from the show floor, featuring Stephanie Slater and members of the University of Minnesota bee lab. Stephanie shares what it takes to organize a successful honey show, from publishing rules months in advance to building categories that encourage broad participation. With entries nearly doubling from the previous year, the Midwest Honey Bee Expo honey show continues to grow,...

Varroa Management Planning: Tools and Strategies (Bee Science)

Beekeeping Today Podcast

In this Bee Science Short, Dr. Dewey Caron continues his series on integrated pest management (IPM) for Varroa mites, focusing on the critical step of selecting and applying the right tools at the right time. Dewey emphasizes a simple but essential message: have a plan. Effective Varroa control begins with understanding pest levels, assessing risk, and determining when intervention is necessary based on economic injury levels (EIL). From there, beekeepers must choose appropriate management tools to keep mite populations below damaging thresholds. The episode highlights the importance of...

Varroa Management Guide Update with Dewey Caron (380)

Beekeeping Today Podcast

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...

Midwest Honey Bee Expo Interviews: Comb Honey Innovation and Feeding Solutions (Part 2)

Beekeeping Today Podcast

In this Beekeeping Today Podcast Short, Jeff Ott and Becky Masterman continue their live coverage from the 2026 Midwest Honey Bee Expo, featuring two conversations focused on innovation in comb honey production and hive feeding systems. The episode begins with Mick and Madison Fry, creators of SimplKomb, a comb honey production system designed to simplify harvesting while reducing waste. Their approach integrates production and packaging into a single cassette that fits standard medium frames, allowing bees to build comb directly within the final retail container. The result is a cleaner...

Terra Vera Update: Hive Health, Biosecurity, and Varroa Control (379)

Beekeeping Today Podcast

In this episode of Beekeeping Today Podcast, Jeff Ott and Becky Masterman welcome back Dr. Jeff Pettis and Carlos Perea of Terra Vera for an update on their evolving approach to honey bee health—one that goes beyond traditional varroa control. The discussion begins with a listener question on varroa management in top bar hives, highlighting the complexity of applying existing treatments across different hive configurations. From there, the conversation shifts to Terra Vera’s oxidant-based technology, which mimics natural immune responses found in mammals and honey bees. Carlos explains how...

[Bonus] Short - Midwest Honey Bee Expo Interviews: Beekeepers and Innovations (Part 1)

Beekeeping Today Podcast

In this special Beekeeping Today Podcast Short, Jeff Ott and Becky Masterman record live from the floor of the Midwest Honey Bee Expo, bringing listeners a series of conversations with beekeepers, educators, and innovators shaping today’s beekeeping community. The episode captures the energy of the expo, where hundreds of beekeepers gather to learn, connect, and share ideas. From practical hive management to emerging technologies and equipment, these conversations highlight the diversity of perspectives and experiences within beekeeping. Jeff and Becky begin with David Burns, a well-known...

[Bonus] Short - Winning Honey with Stephanie Slater

Beekeeping Today Podcast

In this Beekeeping Today Podcast Short, Stephanie Slater launches a new monthly series focused on honey shows, judging, and the art of presenting hive products. Stephanie begins by sharing how she got started in beekeeping, tracing her journey from attending an Earth Day presentation to becoming an active honey show competitor and judge. Her story sets the stage for a series designed to make honey shows more accessible to beekeepers at all levels. This first episode focuses on the value of entering honey shows. Stephanie explains how competition raises quality standards, helps beekeepers...

AHB Swarming with Chip Taylor and Gard Otis (378)

Beekeeping Today Podcast

In this episode of Beekeeping Today Podcast, Jeff Ott and Becky Masterman welcome back Dr. Chip Taylor and Dr. Gard Otis for a deep dive into Africanized honey bee swarming behavior—and what it reveals about honey bee biology. The conversation begins with a listener question on comb rotation and foundation use, offering practical spring management tips for replacing old brood frames and encouraging new comb building. From there, the discussion shifts to swarming—one of the most important reproductive behaviors in honey bees. Drawing on decades of research in South and Central America, Chip...

Varroa mites are the most destructive parasite affecting honey bee colonies worldwide. In this Bee Science Short, Dr. Dewey Caron explains how Varroa destructor reproduces, spreads within colonies, and why understanding the mite’s biology is essential for modern beekeeping.

Female Varroa mites enter brood cells shortly before they are capped and reproduce alongside the developing bee. Inside the sealed cell, mites feed on the developing bee and produce offspring that emerge with the young adult bee. Because the mite’s reproductive cycle is closely tied to brood production, populations can increase rapidly during the active season.

Beyond direct feeding damage, Varroa mites also spread viruses that weaken colonies and shorten the lifespan of worker bees. Dewey explains why unchecked mite populations can quickly overwhelm a colony if they are not monitored and managed.

For beekeepers, the key is awareness. Regular monitoring allows beekeepers to track mite levels and respond before populations reach damaging levels. Understanding the biology of Varroa helps beekeepers make informed decisions about management strategies and colony health.

This episode is part of the Bee Science with Dewey series, where Dr. Caron shares practical explanations of honey bee biology to help beekeepers better understand what is happening inside their colonies.
