‘Bee' thankful for the evolution of pollen
Missouri U. researchers discover wildflower's spiny pollen
adapts to help plants reproduce
Over 80% of the world's flowering plants must reproduce in order to produce new flowers, according to the U.S. Forest Service. This process involves the transfer of pollen between plants by wind, water or insects called pollinators -- including bumblebees.
In a new study, researchers at the University of Missouri discovered spiny pollen -- from a native wild dandelion species in the southern Rocky Mountains -- has evolved to attach to traveling bumblebees. Using a highly detailed electron scanning microscope, the research team could observe the microscopic surface of the spiny pollen, which otherwise looks like yellow dust to the naked eye.
"The spiny pollen actually acts like Velcro," Lynn said. "So, when bees are harvesting pollen for food, this pollen is sticking to their hair. It's a great example of mutualism where the plant needs the pollinator to reproduce and the pollinator needs the plant for its food."
The researchers plan to study how a bumblebee's hairs contribute to this process.

If you're sticking close to home these days and looking for something to do (or looking for something for kids to do) the Xerces Society has several bee monitoring guides and tools worth checking out.
Developed for conservationists, farmers, land managers, restoration professionals, and community scientists, the Bee Monitoring Protocol and Community Science Guides are useful for documenting how native bee communities change through time in pollinator habitats. The publications include an introduction to bee identification, a detailed monitoring protocol, and data sheets for different habitat types.
We will dive into the fascinating world of bees – managed and wild - and learn about the current research to keep them healthy from leading experts in the field. You will also get an opportunity to tell us your concerns about bees and pest management in agriculture and discuss how we can shape the future of CA agriculture together.

The California Master Beekeeper Program (CAMBP), directed by Extension apiculturist Elina Lastro Niño of the University of California-Davis Department of Entomology and Nematology, is hosting two short courses in early August: one on “Planning Ahead for Your First Hives” and the other, “Working Your Colonies.”
Each will take place from 9 a.m. to 4 p.m. in the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, west of the central campus. The deadline to register is Thursday, Aug. 1.
“These courses are foundational to beekeeping husband excellence,” said Wendy Mather, program manager. “They are great for folks who are thinking about getting bees next season, as well as those who currently have bees and want to ensure they're doing whatever they can to ensure the success of their hives.”
The classes are not required to become a California Master Beekeeper, but are highly recommended, as “they will help folks prepare to become a science-based beekeeping ambassador,” Mather said. Instructors are Elina Niño and CAMPB educational supervisor Bernardo Niño, a staff research assistant in the Niño lab.
Planning Ahead for Your First Hives
“Planning Ahead for Your First Hives” will take place Saturday, Aug. 3 and will include both lectures and hands-on activities. Participants will learn what's necessary to get the colony started and keep it healthy and thriving. They will learn about bee biology, beekeeping equipment, how to install honey bee packages, how to monitor their colonies (that includes inspecting and monitoring for varroa mites) and other challenges with maintaining a healthy colony.
The course is limited to 25 participants. The $105 registration fee covers the cost of course materials (including a hive tool), lunch and refreshments. Participants can bring their bee suit or veil if they have one, or protective gear can be provided. For more information or to register, see https://registration.ucdavis.edu/Item/Details/572.
Working Your Colonies
“Working Your Colonies” will take place Sunday, Aug. 4 and will include both lectures and hands-on activities. Participants will learn what is necessary to maintain a healthy colony. Lectures will cover advanced honey bee biology, honey bee integrated pest management, and products of the hive. Participants also will learn about queen wrangling, honey extraction, splitting/combined colonies, and monitoring for varroa mites.
The course is limited to 25 participants per session. The $175 registration fee covers the cost of course materials, lunch and refreshments. For more information or to register, see https://registration.ucdavis.edu/Item/Details/559.
Participants can bring their bee suit or veil if they have one, or protective gear can be provided. All participants are to wear closed-toed and closed-heel shoes, long pants and a long-sleeved shirt.
The California Master Beekeeping Program uses science-based information to educate stewards and ambassadors for honey bees and beekeeping. For more information, contact Mather at firstname.lastname@example.org.
Research to help plant growers
protect bees and manage pests.
A group of scientists from the IR-4 Project is doing research to explore the relationships between bees, environmental horticulture plants, and pesticides. This group has put together a database allowing users to create customized plant lists for bees, to research articles, to find pollinator news updates and to research best management practices documents. Check it out:
The research is primarily targeted towards helping environmental horticulture growers, but the information should also produce valuable resources for home gardeners or anyone interested in the interplay between bees, plants, and pesticides.
