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.

Avocado is a neotropic tree which has been commercialized world-wide, yet it's native pollinators have been little studied. The most frequently studied pollinator has been the old-world insect, Apis mellifera. In commercial orchards it is common practice to introduce honey bee colonies, although it is not clear exactly what the extent of their effect is in California orchards in the presents of native bees and other pollinators. The purpose of this study is to evaluate the range of avocado flower visitors and to assess whether those numbers can be affected by the introduction of gardens that might promote their numbers in the orchards during the avocado bloom period.
Measuring pollinator performance is difficult because of weather impacts, alternate bearing habit and the high level of fruit shedding in avocado. In this study, pollination gardens have been established in three avocado orchards in coastal California near Santa Barbara, just north of Los Angeles. These gardens have been established since 2014 with a variety of perennials that can supply nectar and pollen over the year and especially during the prolonged flower season. The three orchards where the gardens are established each exceed 40 ha. Gardens have been established in just one portion of the orchards, so that flower visitation can be assessed near and far from the gardens. The individual visitation activity of flower visitors was evaluated per unit time and their abundance on avocado flowers near the gardens and away from the gardens. Visitation was also similarly assessed on the pollinator gardens. Pan traps were also used to assess the presence of native bees in the orchards.
The most abundant visitors in all years have been Syrphid spp. along with a variety of other flies and wasps. The most abundant native bee species have included Ceratina, Halictus, Agapostemon and several andrenid species. The highest diversity and abundance of visitors has occurred after the high rainfall year of 2016/17 after previous drought years.

I recently came across a library of all kinds of images of pests, diseases and crops. It has lots of entries, such as “Bees of the United States”:
And images of citrus pests and diseases and even different cultivars of citrus, under “Citrus ID”:
'Xie Shan" citrus cultivar
And even a few avocado images:
But there's a heck of a lot more.
Clicking on the different links and their volumes of images will take some time because of the shear number. The images have been collected as a public data base for not only academics, but also for the general public. At present, it's not too easy to search, but it's worth a look.
Here's a list of the different categories that can be perused:
