    304 - Millions of Solitary Bees in a Cemetery: Andrena regularis Aggregations and Parasite Dynamics | PolliNation

    Dr. Bryan Danforth of Cornell University joins the podcast to discuss a new Apidology study led by Steven Hodge on emergence dynamics and host–parasite associations in a massive cemetery nesting aggregation of the solitary bee Andrena regularis. Using emergence traps checked daily for 40 days at East Lawn Cemetery near Cornell, the team estimated a mean population size of 5.5 million emerging bees within a compact area and documented synchronized host emergence with more gradual, delayed emergence by Nomada cuckoo bees, plus low-frequency associates including a meloid beetle and a conopid fly. Danforth explains A. regularis biology and its exceptional importance and effectiveness as an apple pollinator, highlights evidence for greater female investment as a potential sign of abundant resources, and argues cemeteries and other nest sites may be overlooked conservation assets, supported by Cornell's Ground-Nesting Bees iNaturalist initiative.

    302 - Forest Log Landings for Bees | PolliNation

    Log landings serve as a unique way to provision habitat in otherwise closed-canopy forests, providing refuge for wild bees and wasps. UMass Amherst PhD candidate Aliza Fassler unpacks her research on seeding log landings with native plants, and speaks to the pollinator assemblages that use them.   Learn more about Aliza's research in this technical report: https://t.ly/gM2hR Visit the UMass Extension pollinator resources page: ag.umass.edu/pollinators

    301 - Mason Bees 101: How to Care for Blue Orchard Bees (and Stop Houdini Flies) | PolliNation

    Thyra Mckelvie joins PolliNation to discuss managing blue orchard bees (mason bees). Thyra is the Managing Director and Solitary Bee Educator at Rent Mason Bees. She outlines three essential care steps: start with clean, openable nesting material of proper size, remove nests at the end of spring to protect developing bees from summer predators, and harvest/clean cocoons in fall to control pests and disease. In addition, Thyra covers the key pests of mason bees include pollen mites, Houdini flies, chalkbrood fungus, and monodontomerus wasps, plus sterilization methods.

    300 - PolliNation RELOADED | PolliNation

    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 Hopkins – Washington State University Lab Page: https://bees.wsu.edu/about-hopkins-lab/ Dr. Priya Chakrabarti (Basu) – Washington State University Research Website: https://priyadarshinichakrabarti.com Harry Vanderpool – Hear our episode with Harry: https://youtu.be/CSiDXLmgxjU?si=D796BGDFkSUMMT59 00:00 Nicole Bell - episode highlight 00:25 Podcast Origins and Growth 01:45 Episode 300 New Era 03:09 Meet Nicole Bell 06:04 Meet Brandon Hopkins 08:48 Meet Priya Chakrabarti  10:49 Harry Vanderpool Updates 14:30 Co-Hosts Vision Ahead

    299 - Inside Idaho's Alfalfa Leafcutter Bee Cocoon Testing Center | PolliNation

    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-experiment-station/centers/parma 00:00 X-Ray Cocoon Clues 01:12 Podcast And Guest Intro 02:48 New Extension Role 05:22 Why Leafcutters Win 08:14 Cocoon Center Basics 11:28 X-Ray Diagnostics 14:28 Using Results For Rates 19:35 Sampling And Reports 23:09 New Programs And Tech 27:44 Pollinator Garden Impact

    298 - Wibee: A Simple App to Measure Pollination Activity in Your Orchard | PolliNation

    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.

    297 - Pollen Wasps: A Parallel Path to Pollination | PolliNation

    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 ( 00:00 Gondwana Origins Teaser 00:58 Podcast Intro And Guest 02:22 Inside The Entomology Collection 03:49 Why Collections Matter 05:27 Growing The Collection 06:52 What Are Pollen Wasps 09:04 Angiosperms And Shared Origins 11:00 Reverting Back To Carnivory 12:40 Where They Live And Diversity 15:49 Life History Compared To Bees 18:07 How They Carry And Pollinate 19:21 Nests And Plant Hosts 23:31 Research And Conservation Questions
