Take Benicia, Solano County. Its little hot spots near the Carquinez Strait--think trees growing near sun-warmed asphalt--yield early almond blooms, often as early as New Year's Day.
At the Matthew Turner Park in Benicia, today, honey bees buzzed around the almond blossoms, gathering pollen and nectar. But the honey bees were not alone.
Yellow-faced bumble bees, Bombus vosnesenskii, were foraging, too. It's always a treat to see honey bees in the almonds, but it's a double treat to see a bumble bee.
Pollination of California's almond acreage is as intense as it is huge. The 2016 almond acreage totaled 1.2 million acres--940,000 bearing and 300,000 acres non-bearing, according to a report issued in April 2017 by the California Department of Food and Agriculture, in cooperation with the National Agricultural Statistics Service of the U.S. Department of Agriculture. This year, California has more than a million acres of bearing almonds, and each acre requires two bee hives for pollination. The leading almond-producing counties? Kern, Fresno, Stanislaus, Merced and Madera.
Solano County, of course, doesn't make the list, but when you want to see the early almond blooms, it's the place to "bee."
Which reminds us of the research, Synergistic Effectgs of non-Apis Bees and Honey Bees for Pollination Services, published by an international team of scientists in the Jan. 10, 2013 edition of The Proceedings of the Royal Society B. The researchers, including pollination ecologist Neal Williams of UC Davis, found that honey bees are more effective at pollinating almonds when other species of bees are present.
When blue orchard bees and wild (non-managed) bees such as bumble bees, carpenter bees and sweat bees, are foraging in almonds with honey bees, the behavior of honey bees changes, resulting in more effective crop pollination, said lead author Claire Brittain, then of the Neal Williams lab. She earlier worked as a post-doctoral fellow at Leuphana University of Lüneburg, Germany.
“These findings highlight the importance of conserving pollinators and the natural habitats they rely on,” Brittain told us in a news release. “Not only can they play an important direct role in crop pollination, but we also show that they can improve the pollination service of honey bees in almonds.”
Agroecologist Alexandra-Maria Klein, now a professor at Leuphana University, served as the project lead while a postdoctoral fellow in the UC Berkeley lab of conservation biologist/professor Claire Kremen. In fact, Klein and Kremen initiated the project in 2008 and continued working on the project together in 2009 and 2010. Williams joined the team in 2010.
Native pollinator specialist Robbin Thorp, now a distinguished emeritus professor of entomology at UC Davis, identified 50 different species that the team found. They included bumble bees, small carpenter bees, sweat bees, digger bees, mining bees and blue orchard bees.
Take a look around you during the almond pollination season. The honey bees are not alone.

UC Davis entomology major Lohitashwa “Lohit” Garikipati, who will be displaying his praying mantis collection at the Bohart Museum of Entomology during the seventh annual UC Davis Biodiversity Museum Day on Saturday, Feb. 17, is keenly interested in sharing information about insects.
“Every organism on the Earth has value, and we should respect that,” says Garikipati, a third-year entomology student who rears praying mantises. “Regardless of its appearance, its lifestyle, or its behaviors, all the life that we see here on Earth is the result of change billions of years in the making. There's nothing that is scary, or disgusting; fear is taught, and the sooner we stop fearing and start appreciating, the sooner we can save as much biodiversity on the Earth as we can. It only takes one second to decide you care enough to stop fearing, so why not start now?”
Lohit (pronounced “Lo-Heat”) serves as secretary of the UC Davis Entomology Club, which is advised by forensic entomologist Robert Kimsey of the UC Davis Department of Entomology and Nematology.
“What I like most about mantids, besides their amazing appearance, is how charismatic they are compared to other insects,” says Lohit. “Their behavior varies between species, but all have this awareness that most other insects lack, which make them fun to interact with and study. Their predatory behavior is also interesting.”
Garikipati, a native of Pleasanton, Calif., says he's been interested in praying mantises since elementary school. “I started rearing native species in the 5th grade,” he recalled. “I kept a Mantis religiosa (European mantis) and hatched the ooths she laid. Since then I've had in my collection over a dozen species throughout that time. There wasn't any one species that I ended up consistently rearing, as I would get nymphs, rear them ‘til I got a second generation, then trade or sell them to get a new species. I will definitely be keeping orchids as long as I can though!”
Currently in his collection:
- Two adult female orchid mantises (Hymenopus coronatus)
- A pair of male and female adult Australian rainforest mantises (Hierodula majuscula)
- A pair of male and female 4th instar ghost mantises (Phyllocrania paradoxa)
- A 5th instar female African spiny flower mantis (Pseudocreobotra wahlbergii)
- Three third instar Decimiana bolivari (there's no agreed upon common name, but they can be called South American dead leaf mantises, he says).
Lohit traces his interest in all insects to early childhood. “I've had an innate interest in animals in general as long as I can remember, insects just happened to be the most fun and most easy to find and study! The thing that fascinates me most about insects is their massive diversity and the ability insects have to surprise us by breaking what we think an animal can do. For example, wasps photosynthesizing.”
He is interested in enrolling in graduate school, “possibly in Davis--I'm not quite sure yet. Currently, my career plans involve doing research on mantis ecology, as well as updating taxonomy. Many genera need a lot of work and updated descriptions for the species they contain. I would like to be a professor as well!”
When he's not working with insects, Lohit enjoys “playing guitar, going to the gym, or trying to climb the mountain of homework or studying I have!”
Meanwhile, visitors can see learn all about praying mantises--and hold and photograph them--from 9 a.m. to 1 p.m., Feb. 17 at the Bohart Museum, located in Room 1124 of the Academic Surge Building, Crocker Lane. The Bohart, directed by entomology professor Lynn Kimsey, is the home of a global collection of nearly 8 million insect specimens, and a live "petting zoo," comprised of Madagascar hissing cockroaches, stick insects and tarantulas. Also on Feb. 17, highlights at the Bohart Museum will include the 500,000-specimen butterfly/moth collection, curated by entomologist Jeff Smith; and an insect collection display by Smith and fellow Bohart Museum associates Fran Keller and Dave Wyatt from their latest expedition to Belize. "You'll be able to see the tremendous diversity of butterflies, moths and mantids, and talk to the scientists who have just returned from there," said Tabatha Yang, education and outreach coordinator. "There will be orchids and orchid bees connecting the Bohart Museum's work with plant biology and science."
The Bohart Museum is one of the 13 museums or collections on campus where visitors can explore “the diversity of life” on Biodiversity Museum Day. All are within walking distance on campus except for the Häagen-Dazs Honey Bee Haven on Bee Biology Road and the Raptor Center on Old Davis Road.

Back back to "bugged."
You'll see "bugs" at four sites: the Bohart Museum of Entomology, Häagen-Dazs Honey Bee Haven, the Nematode Collection, and at the Design Museum's special exhibition, It's Bugged: Insects' Role in Design.
Bohart Museum of Entomology
The Bohart Museum of Entomology, open from 9 a.m. to 1 p.m. on Feb. 17, is the home of a global collection of nearly 8 million insect specimens. Highlights will include the 500,000-specimen butterfly/moth collection, curated by entomologist Jeff Smith; display of praying mantises, including orchid mantises, by UC Davis entomology student Lohit Garikipati; and an insect collection display by Smith and fellow Bohart Museum associates Fran Keller and Dave Wyatt from their latest expedition to Belize. "You'll be able to see the tremendous diversity of butterflies, moths and mantids, and talk to the scientists who have just returned from there," said Tabatha Yang, education and outreach coordinator. "There will be orchids and orchid bees connecting the Bohart Museum's work with plant biology and science."
Häagen-Dazs Honey Bee Haven
Häagen-Dazs Honey Bee Haven, a half-acre bee demonstration garden next to the Harry H. Laidlaw Jr. Honey Bee Research Facility, Bee Biology Road, will be open from noon to 4 p.m. Activities include catch-and-release bee viewing and making "Feed the Bees" seed cookies. The haven was installed in the fall of 2009. A six-foot-long bee sculpture, Miss Beehaven, by artist Donna Billick, co-founder and co-director of the UC Davis Art/Science Fusion Program, anchors the haven. Other art, coordinated by entomology professor Diana Ullman, co-founder and director of the Art/Science Fusion Program, and Billick, also graces the haven. Guests will see bee condos occupied by leafcutter bees and mason bees. Robbin Thorp, distinguished emeritus professor of entomology, has recorded more than 80 different species of bees in the garden. Coordinator: Christine Casey, academic program management officer.
Design Museum
The Design Museum will be open from noon to 4 p.m. in Room 124 of Cruess Hall. Professor Timothy McNeil and curator Adrienne McGraw will staff the exhibit, It's Bugged: Insects' Role in Design, which explores the connections between people and insects. This is a special opening just for Biodiversity Museum Day. (The exhibit opened Jan. 8 and continues through April 22; regular hours are weekdays from noon to 4 p.m. and Sundays from 2 to 4 p.m.) "It's Bugged" includes art from faculty and graduate students. It will include hornet nest paper art and beetle gallery sculptures, both the work of Ann Savageau, professor emerita, UC Davis Department of Design; insect-themed clothing; insect specimens from the Bohart Museum of Entomology and insect photos from UC Davis alumnus Alex Wild, curator of entomology at the University of Texas, Austin. Coordinators: Timothy McNeil, professor, and Adrienne McGraw, exhibition curator.
Nematode Collection
The Nematode Collection will be open from noon to 4 p.m. in the Science Laboratory Building, central campus (off Kleiber Hall Drive). Visitors can expect to see live and preserved nematode specimens. Highlights include the huge jars of whale intestinal worms. Nematodes, also called worms, are elongated cylindrical worms parasitic in animals or plants or free-living in soil or water. They exist in almost every known environment. The many different species eat everything from bacteria and fungi to plant and animal tissue. Coordinator: Corwin Parker, nematology doctoral student.
For further information on the Biodiversity Day, access the UC Davis Biodiversity Museum Day website for maps and more information, including social media links, Facebook and Twitter, @BioDivDay. There's also capsule information on the Department of Entomology and Nematology website.
Last year's Biodiversity Museum Day drew some 4000 visitors to campus. This year? Many more are expected.

Do you know where your nematodes are? If you're a grower, you should.
"To make informed management decisions and ensure that environmentally damaging soil fumigants are applied only when and where needed, growers need to know precisely the density and distribution of pest nematodes," says nematologist Amanda Hodson, a professional researcher in the UC Davis Department of Entomology and Nematology who will present a departmental seminar at 4:10 p.m., Wednesday, Jan. 31 in 122 Briggs Hall.
Hodson, who will deliver the hourlong seminar on "Molecular Detection and Integrated Management of Plant Parasitic Nematodes," studies the interrelationships between nematode pests, ecosystem functioning and management decisions.
"Molecular methods overcome some of the drawbacks of the labor and time intensive process of nematode detection," she says. "Our analysis has established the accuracy of real time PCR (qPCR) primers which accurately differentiate and quantify several pest nematodes from other nematodes in the soil including lesion nematode (Pratylenchus vulnus), ring nematode (Mesocriconema xenoplax) and two separate groups of root knot nematodes (Meloidogyne spp.). Integrated management of these soil pests requires better understanding of the interactions between nematode pest suppression, soil food webs, management tactics, crop productivity, and soil health. Our experiments link managing for nematode pest suppression with other desired ecological outcomes such as increased soil organic matter and nutrient cycling in cropping systems such as almonds, tomatoes and carrots."
Hodson's research integrates plant and root biology with the fields of entomology, nematology, acarology and biogeochemistry. She completed her doctorate in entomology at UC Davis in 2010 on the ecological effects of a biological control agent in pistachio orchards, finding that the entomopathogenic nematode, Steinernema carpocapsae, caused temporary changes in native soil food webs. Following up on these results in the laboratory, she found that the European earwig (Forficula auricularia) could serve as a novel host for the nematode. This susceptibility depended on host body size with significantly higher mortality rates seen in larger earwigs.
The departmental seminars (see schedule) are open to all interested persons. Seminar coordinators are assistant professor Rachel Vannette, Extension apiculturist Elina Lastro Niño and doctoral student Brendon Boudinot of the Phil Ward lab.
