Pollination | A Pollinator Health Podcast

As the 300th episode approached Dr. Melathopoulos started to get nervous. He had been doing the show since 2018. When his podcasting hero Melvyn Bragg hung up his podcasting mic last year, Dr. Melathopoulos wondered if he should do the same. But no. Polli-Nation is officially outgrowing its borders! While the show's roots are at OSU Extension, we are thrilled to welcome a new collaborative hosting team. By bringing in the expertise of Nicole Bell (East Coast/UMass), and Drs. Brandon Hopkins and Priya Chakrabarti Basu (WSU), we are expanding our coverage from the wild bee meadows of New England to the high-tech honey bee storage facilities of the Pacific Northwest. Hear the different hosts visions for the future of pollination in this episode.  Nicole Bell – UMass Amherst Extension: https://www.umass.edu/bee-campus/about/directory/nicole-bell The Pollinator Steward Certification: https://www.umass.edu/agriculture-food-environment/resources/pollinators/pollinator-steward-certification-program Dr. Brandon H

 In this episode Dr. Melathopoulos speaks with Dr. Armando Falcon-Brindis, assistant professor and extension specialist in entomology at the University of Idaho's Parma Research and Extension Center and director of the Parma Cocoon Testing Center. Dr. Falcon-Brindis explains why alfalfa leafcutter bees are far more effective than honey bees at pollinating alfalfa seed and describes how the lab uses X-ray imaging to assess cocoon health by counting live larvae, dead cells, pollen balls, machine damage, predators, parasites, and signs of pathogens, with follow-up dissections when needed. He details grower sampling methods, recommended bee release rates, and sex-ratio testing, then outlines new program efforts including a demonstration pollinator garden, field-based IPM trainings, and modernization of diagnostics with digital X-ray and other technologies.  University of Idaho Faculty Profile: https://www.uidaho.edu/people/afalconbrindis Parma Research and Extension Center: https://www.uidaho.edu/idaho-ag-expe

 Dr. Melathopoulos talks with Dr. Hannah Gaines-Day (University of Wisconsin–Madison) about WiBee (W-I-B-E-E), an app created after conversations with Wisconsin apple growers who wanted to know whether wild bees provide enough pollination or if honeybee rentals are needed. The app has users stand still and record insect visits in a standardized 3x3-foot area for five minutes, tallying easy-to-identify functional "morpho groups" (honeybee, bumblebee, large dark, small dark, green bee, and non-bees) while also logging weather, habitat, and flower abundance. Validation work compared Wibee visitation rates with pollen deposition in apple and cranberry, finding a tight relationship in cranberry but not apple due to pollen source ambiguity; a follow-up will test relationships with fruit set, and pumpkin data are pending. Wibee has been widely adopted by Master Gardeners, has generated about 15,000 publicly viewable surveys, and may be compared with camera-based monitoring in future work. Essential Links: WiBee Of

 In this episode of Pollination, host Dr. Andony Melathopoulos talks with Dr. Elizabeth Murray ( Mt. James Entomological Collection, Washington State University) about pollen wasps (Masarinae) and how they represent a rare, parallel shift to bees from carnivory to provisioning young with pollen. The conversation covers pollen wasp origins around 125 million years ago alongside bees, likely in arid Western Gondwana as angiosperms rose, their global but dry-region-biased distribution, low species diversity (

 Christine McDonald discusses her family-run beekeeping operation based in Terrace, British Columbia. Living in a remote area, Christine emphasizes the importance of in-person gatherings for bee education despite the proliferation of online resources. She explains how her family has turned geographical challenges into strengths, mentioning their diverse range of products, including honey and candles, and their reliance on wild forage like fireweed. Christine highlights the seasonal challenges they face, such as preparing colonies for winter and managing a short beekeeping season. She also elaborates on their approach to raising queens and maintaining their operation's sustainability. Additionally, Christine's Instagram presence has become a pivotal part of connecting with the wider beekeeping community.

 This week, we talk with Ryan Lieuallen of Sweet Bee Honey Company in Milton-Freewater, Oregon. Ryan shares insights into the significant challenges and changes within the beekeeping industry, including high winter mortality rates and the potential economic impacts of the Tropi mite infestation. We discuss the emergence of new Varroa treatments and innovative strategies for creating sustainable bee pastures for bees. Explore Ryan's dedication to maintaining a five-generation beekeeping heritage while adapting to future challenges in beekeeping and sustainable agriculture.

 In this episode of the podcast, Dr. Zach Portman discusses a new paper addressing the problem of ghost records in bee data. These records often lack physical specimens, creating challenges for verifying data of bee species. Dr. Portman explains the process and complications behind collecting and verifying bee data, emphasizing the importance of preserving specimens. The conversation also delves into the implications of ghost records for conservation efforts and taxonomy, proposing that funding agencies should require proper storage plans for collected specimens.

Pollinator Pathway is a national organization dedicated to the establishment of native plant communities for pollinators that are managed without pesticides. It got started in the Western US in Bend, Oregon and this week we hear from two board members, Gwen Bartonek and Lisa Sanco, about the many activities the organization has pulled off in Oregon's High Desert city.

The attention to California almonds, means the pollination of Washington State tree fruits is often overlooked. But the massive pollination effort in Washington is a huge effort and may be facing potential problems. Harry and Andony catch up with commercial beekeeper Tim Hiatt to discuss tree fruit pollination, as well as Tim's efforts to advocate for beekeeping in the Washington legislature.   

This week on PolliNation Itai Kanot and Shelbi Perkins from BeeHero discuss how their in-hive and in-field sensors are improving pollination efficiency by providing real-time data on bee colony strength, benefiting both growers and beekeepers. BeeHero: https://www.beehero.io/

Dr. Diana Cox-Foster joins us to discuss her and her team's research at the USDA on honeybee and native bee competition. From lab tests to field studies, they uncover the effects of this competition on pollination.

Queen Bee Honey Company in Alpine, Oregon built up from a Datsun pickup truck to a commercial beekeeping business. In this episode we hear about how Karen Finley built her business and the increasing problem of lack of summer forage for honey bees in Oregon's Willamette Valley.      

The BEEvent, hosted annually by the Linn County Master Gardeners, provides gardeners and small farmers with essential knowledge and practical tools to support and protect bee pollinators.

While there has been a lot of attention to the plight of wild bees, we are increasingly discovering that there is a lot more that we don’t know. A state checklist of bees is a great starting point for taking stock of what we do know. This week I am joined by Chanda Bartholomew, who is an Entomology Collection Taxonomist with the Pest Program in the Plant Protection Division of Washington State Department of Agriculture. She is the lead author of “An annotated checklist of the bees of Washington state” that was published in the Journal of Hymenoptera Research in November of 2024.  Link to the article: https://jhr.pensoft.net/article/129013/
