Guest Speaker Dr. Juliana Rangel

Dr. Juliana Rangel of NCSU spoke at the PCBA September meeting. Dr Rangel gave a Dr. Juliana Rangelpresentation on the relationship between honey bee health and pollination in Agro-ecosystems. Some of the topics she discussed were.

  1. Importance of honey bees as pollinators, value of honey bee pollination services in the US, and some definitions of ecosystems, agro-ecosystems, and ecosystem services (pollination being an important ecosystem service to humans)
  2. Basics of pollination biology, morphological adaptations of honey bees for pollination
  3. Economic impact and benefits of honey bee pollination nationwide and in NC
  4. Costs of honey bee pollination and of lack-there-of (pests and pathogens to honey bees and their impact on honey bee health and productivity).
  5. Honey bee health vs. ecosystem health

She also shared a few very interesting stats:

  • 75% of flowering plants rely on animal pollination
  • 33% of the food we consume is pollinated by honeybees
  • Multi-million dollar crops such as Almonds, Apples and Blueberries are 90% reliant on honey bee pollination.
  • Annual value of honey bee pollination on agricultural products is about 15 billion dollars.

Dr. Rangel is a postdoctoral fellow at NCSU. She was awarded one of only 15 National Science Foundation Postdoctoral Research Fellowships in Biology titled “Queen supersedure in honey bees: how and why do workers replace their mother queen with a sister queen?” The award is for $189,000 over three years. Juliana’s research addresses the collective decision-making of honey bee colonies over colony level reproduction, which has important pragmatic implications for the apicultural industry in maintaining stable and productive colonies.
