The six-member team, including Elina Lastro Niño, associate professor of UC Cooperative Extension, UC Davis Department of Entomology and Nematology, is sharing an online pre-print version of their research on the yield characteristics of a self-compatible almond variety.
The paper, titled “Comparison of Yield Characteristics of Independence, a Self-Compatible Almond Variety, as Affected by the Presence of Honey Bee Pollinators,” is online at https://www.researchsquare.com/article/rs-3870916/v1 during the review process for Scientific Reports.
Co-authors with Niño are Angelita De la Luz, Beeflow Inc. Smart Pollination Services; Bernardo Niño, Xerces Society for Invertebrate Conservation (he is formerly from UC Davis); William Stacy, UC Davis Extension; and Arathi Seshadri, U.S. Department of Agriculture's Agricultural Research Service (USDA-ARS).
The abstract:
“Until recently, all the almond varieties grown globally, have been self-incompatible, a fact that drives the interdependent relationship between almond growers and the beekeepers that provide honey bee colonies for pollination. Recently, almond growers have begun a transition to self-fertile varieties, such as Independence, which do not require genetically distinct pollen to produce kernels. However, this transition often occurs under the impression that due to self-compatibility, one can eliminate the honey bee rentals for pollination and thereby reduce costs for these orchards, but the impact that eliminating rented colonies would have on almond quality and yield are not fully understood.”
“Here, we explore the extent to which yields for Independence variety vary with and without honey bee pollination and across a range of hive stocking densities in the San Joaquin Valley of California. We found that access to honey bee pollination significantly improves nut set and whole tree yields, ultimately resulting in economically meaningful gains to growers. Our economic model shows how specific honey bee hive stocking density recommendations depend on the surrounding landscape and will change as acreage of self-fertile varieties continues to increase over time."
In their research, the authors point out that
- The United States is the world's largest almond producer, with California accounting for nearly 80 percent of the world's almond supply
- Almond orchards rank as the highest in their need for pollinators, specifically honey bees
- California's almond orchards need more than a million honey bee colonies every season for pollination, brought in all over the country and globally
- There are insufficient colony numbers stemming from poor nutrition, improper use of agrochemicals, loss of natural habitat and increased incidences of pests and diseases,
- Until recently, all the almond varieties grown in California have been self-incompatible and almond growers depend exclusively on beekeepers to provide honey bee colonies for pollination
"For growers and beekeepers alike, the question at the forefront is to determine the extent to which self-fertile varieties such as Independence, reduce the dependency on pollination services rendered by managed honey bees," the authors wrote. "Growers specifically, are also interested in knowing any differences in yield quality and quantity resulting from absence of bee-pollination-mediated pollen transfer and ovule fertilization, given that previous studies have reported higher oleic to linoleic ratio in almonds from cross-pollinated trees and this high ratio is most favorable for consumers seeking health benefits."

And if you're part of the UC Davis-based California Master Beekeeper Program (CAMBP), it takes a lot of worker bees from all facets to succeed.
We congratulate CAMBP for its well-deserved recognition at the recent UC Davis Staff Assembly's Citation of Excellence ceremony.
CAMBP director and founder Elina Lastro Niño, associate professor of Cooperative Extension and a member of UC Davis Department of Entomology and Nematology faculty, and co-program manager Wendy Mather won a Faculty-Staff Partnership Award.
Niño, UC Extension apiculturist since 2014, founded CAMBP in 2016. Mather joined the program in March of 2018. Also integral to the program is Kian Nikzad, but as a newer employee, was ineligible to be nominated.
The awards ceremony, held Sept. 12 in the International Center on campus, singled out “some of our most exceptional UC Davis individuals and teams,” Chancellor May said in his presentation.
Nominators of "The Bee Team" (Kathy Keatley Garvey, Nora Orozco and Tabatha Yang of Department of Entomology and Nematology) lauded Niño and Mather for providing a “program of learning, teaching, research, and public service, goes above and beyond in delivering comprehensive, science-based information about honey bees and honey bee health. They continually and consistently develop, improve, and refine their statewide curriculum that educates stewards in a train-the-trainer program to disseminate accurate, timely, and crucial information. Honey bees pollinate more than 30 California crops, including almonds, a $5 billion industry (no bees, no pollination, no almonds). Indeed, California produces more than a third of our country's vegetables and three-quarters of our fruits and nuts. However, colony losses are alarming due to pesticides, pests, predators and pathogens.”
As of Sept. 15, 2023, CAMBP has donated 34,000 hours of volunteer time and served 209,000 individuals in education, outreach and beekeeping mentorship. If a volunteer hour were to be calculated at $26.87, CAMBP has given $913,580 back to California in service of science-based beekeeping and honey bee health.
Its website, accessible to the public, offers a list of classes and knowledge-based information, including backyard beekeeping, bees in the neighborhood, bees and beekeeping regulations, defensive bees, live honey bee removals, and protecting pollinators.
“Bottom line,” the nominators concluded, “our ‘B' Team is really an ‘A' Team, an outstanding example of UC Davis teaching, research and service; a team providing exemplary service and contributions; and a team that creates and maintains high morale and embodies the Principles of Community.”
Joint Statement. In a joint statement following the awards ceremony, Mather and Nikzad said: “We share this award with our passionate and caring member volunteers. Our members are deeply committed to honey bee health, science-based beekeeping practices, and, most importantly, to each other. Their enthusiasm and dedication drive our mission forward. We wish to acknowledge Elina Niño for her visionary leadership; she has brought together various stakeholders, including growers, bee breeders, commercial, sideline, and hobbyist beekeepers, as well as the general public, through CAMBP, UC Davis, UC Agriculture and Natural Resources (UC ANR) and UC Cooperative Extension (UCCE). We missed having her at the ceremony.”
Well deserved! A tip of the bee veil to CAMBP! You're smokin'

National Honey Bee Day is Saturday, Aug. 19 and you're invited to join this oh-so-sweet celebration!
Launched in 2009, National Honey Bee Day takes place on the third Saturday of August. The event originated when a small group of beekeepers petitioned the U.S. Department of Agriculture "to honor" the honey bees and beekeepers.
HoneyLove.org, a Los Angeles-based honey bee educational non-profit organization, manages National Honey Bee Day and boosts "the educational outreach, community action and advocacy efforts to protect the health and well-being of honey bees," according to its website.
California Master Beekeeper Program. While we're honoring bees, we should also honor the UC Davis-based California Master Beekeeper Program (CAMBP), founded and directed by Elina Lastro Niño,associate professor of Cooperative Extension and a member of the faculty of the UC Davis Department of Entomology and Nematology.
"The award seeks to highlight teams who actively develop and encourage faculty/staff partnerships and as a result are able to make notable contributions to UC Davis that contribute to the University's Mission of Teaching, Research, and Service; and who exemplify outstanding achievement and/or service," according to Staff Assembly officials.
At the time of the nomination (March 15, 2023), CAMBP had
- Given 32,000 hours of volunteer time (Beneficial Educational Experiences) and served 186,630 individuals in education, outreach and beekeeping mentorship. If a volunteer hour is worth $26.87, the program has given $859,840 back to the state of California in service of science-based beekeeping and honey bee health.
- Enrolled 185 Honey Bee Ambassadors (a level established in 2021), 494 Apprentice, 93 Journey level candidates and certified 20 Master level beekeepers. There are 12 members in 2023 participating in their Master Capstone projects.
- Recorded 3752 hours since the team began tracking Continuing Education Experiences in 2020.
- Embarked on a project updating a safety manual.
National Honey Bee Day is also a good opportunity to learn about bees, our mini-agricultural workers that pollinate one-third of the food we eat.
The book includes 16 color plates (images contributed by Kathy Keatley Garvey), spotlighting a bee egg, bee castes, swarms and almond pollination, among others.
Princeton University Press bills the book as "the first up-to-date general reference of its kind published in decades. It is a must-have resource for social insect biologists, scientifically savvy beekeepers, and any scientist interested in bees as a model system."
Among his many honors and recognitions, Johnson was part of The UC Davis Bee Team that won the 2012 Team Award from the Pacific Branch, Entomological Society of America. Other members: Extension apiculturist Eric Mussen (1944-2022); systematist/hymenopterist Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology; native pollinator specialist Robbin Thorp (1933-2019) emeritus professor of entomology; and pollination ecologist Neal Williams (now professor) who specializes in pollination and bee biology.
