Pierre Lau on PolliNation

Pierre Lau is a Ph.D. candidate at Texas A&M University, where he has devoted his time and effort to studying honey bee nutritional ecology. He started building his academic resume at the University of California, San Diego and California State Polytechnic University, Fullerton with honey bee behavioral and native bee pollination studies. As an emerging scientist in the field of honey bee nutritional ecology, Pierre has studied honey bee salt preferences in water, the types of plants honey bees collect pollen from in urban environments, and colony-level macronutrient preferences.

Listen in to learn all about pollen: how to collect and identify it, how it can be used in forensics, and the tools that researchers have developed to source it from particular plants.

“The fun thing about pollen and why palynology is a thing is that every species of plant will produce a unique pollen grain to that species. We can play CSI and forensics here: when you look at the pollen that honey bees collect, you can trace it back to the plant that they were actually visiting.” – Pierre Lau

Show Notes:

  • The different kinds of pollen and it’s structure
  • How the FBI uses pollen to find criminals
  • How to collect pollen
  • Why the process of identifying pollen can be dangerous
  • How Lau is helping Texas beekeepers track the source of their honey
  • How Nuclear Magnetic Resonance can be used to discover the chemical fingerprint of honey originating in a particular region
  • Why honey is one of the top 10 most adulterated products in the United States

“A lot of times when I would sample pollen pellets and beekeepers have a guess about what their bees are collecting, they would be very surprised about what the results actually show. That’s because I think that we are very focused on what we can see: the flowering plants on the floor or shrubs. But a lot of times, the bees will actually go up into trees for their pollen.” – Pierre Lau

Dr. Ramesh Sagili on PolliNation with Andony Melathopoulos

Dr. Ramesh Sagili is an Associate Professor in the Department of Horticulture at Oregon State University and heads up OSUs mighty Bee Lab. He is a regular guest on PolliNation and this week he comes on the show to tell us how to manage colonies for an intense honey flow (happening right now in Western Oregon with the onset of the blackberry flow). It’s also been an unusual year with colonies brooding up early in the year and this brings on the threat of varroa mites. Dr. Sagili explains why an early spring can be both a blessing and a curse and what to do about it.

On today’s episode, learn how to keep your bees healthy and productive, what is most important in maintaining your bees, and how to prevent varroa mites.

“Close to 50% of the nectar that [honeybees] bring in around the year is from blackberries.” – Dr. Ramesh Sagili

Show Notes:

  • How beekeepers can get ready for blackberry nectar season
  • What the process is of getting honey into the colonies
  • What honey supers and queen excluders are
  • Why wax production is such an important factor and can’t be overlooked in honey production
  • Why this season is the perfect time to consider dividing your colony
  • What other opportunities are available for beekeepers during this season
  • How to learn when to perform key maintenance with your bee boxes
  • How to use your honey supers
  • Why beekeepers should be concerned with mites for this season’s bees
  • What treatments are available for varroa mites
  • What Sagili’s lab is doing this upcoming year at Oregon State University

“Oregon is not a great place to raise queens, but I think between the window of June through August, it’s a good time raise your own queens here.” – Dr. Ramesh Sagili
