That's because bees don't fly until the temperature hits around 55, and the thermometer on that wintry day (Jan. 7) refused to budge over 47.
The facility, part of the U.S. Department of Agriculture's Agricultural Research Service, is located next to the UC Davis Department of Entomology and Nematology's Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, west of the central campus.
It slides Davis into the national spotlight as "Pollination Central" and "The Bee Capital of the World." The Davis facility is the newest of five USDA bee research labs in the United States and as the only one in California.
“This is the only USDA bee research team in California—where the action is,” said emcee Paul Pratt, research leader of the Invasive Species and Pollinator Health Research Lab. USDA maintains honey bee research facilities in Tucson, Ariz.; Beltsville, M.D., Baton Rouge, La., and Stoneville, Miss.
“The opening of the USDA-ARS bee lab marks a new opportunity for USDA and UC Davis entomologists to collaborate and investigate serious problems that affect stakeholders,” said Steve Nadler, professor and chair of the UC Davis Department of Entomology and Nematology. “We are very fortunate that the lab was built at UC Davis.”
Plans for the USDA-ARS facility began five years ago at a stakeholders' conference in the Laidlaw facility. Attendees at the November 2015 meeting targeted honey bee health, primarily varroa mites, pesticides and nutrition.
Park-Burris, of Jackie Park-Burris Queens, Palo Cedro--her family has worked with UC Davis researchers for more than 80 years--cut the ribbon with four other stakeholders: almond pollination consultant Robert Curtis of Carmichael, former director and associate director (now retired) of Agricultural Affairs, Almond Board of California; Kevin Adee of Bruce, S.D., president of the American Honey Producers' Association; Brad Pankratz of Can-Am Apiaries, Orland, Calif.; and Darren Cox of Cox Honey Farms, Logan, Utah, a past president of the American Honey Producers' Association.
Pratt introduced newly hired research entomologists, Arathi Seshadri and Julia Fine, who form the Invasive Species and Pollinator Health Research Unit at Davis. They are dedicated toward developing technology that improves colony survivorship through long-term studies of multiple stress factors, he said. "They will develop and transfer integrated biologically based approaches for the management of invasive species and the improvement of pollinator health.”
The speakers centered their presentations around cooperation, camaraderie, and, yes, the cold! (See new story and images on the UC Davis Department of Entomology and Nematology website.)
Park-Burris said it well:
"The California State Beekeepers' Association is overwhelmed that we have a USDA lab to collaborate with our UC Davis lab. We hope there's a lot of collaboration going on. We really look forward to that. As a stakeholder, my family has been raising queens just north of here (Palo Cedro) for over 80 years. Dr. Laidlaw had worked with my uncle and my father. He's been at my house. And he's been through my bees. Julia (Fine) has even already been up to see the queen farm.” (See more information on Harry Hyde Laidlaw Jr., 1907-2003, the father of honey bee genetics, on the UC Davis website.)
“The queen bee breeding industry could definitely use you guys,” Park-Burris continued. “California has all the issues because everybody comes here. …it's very important that we have this lab here and how grateful we are that you have all gone to the work to make this happen."
“We look forward to solving some of our problems—varroa, varroa, varroa--and forage and pesticide interaction,” Park-Burris said, “and all that happens in California during the largest pollinator event in the world. So you're in a good place and we're grateful.”
The bees? They're grateful, too.
The U.S. Department of Agriculture's Agricultural Research Service (USDA-ARS) is gearing up for a ribbon-cutting ceremony and facility tour on Tuesday, Jan. 7 at its newly constructed Honey Bee Research Facility on Bee Biology Road, University of California, Davis.
The event is scheduled to begin at 1 p.m. The site is located next to the Harry H. Laidlaw Jr. Honey Bee Research Facility.
“The focus of this new USDA-ARS honey bee research program is to develop technology that improves colony survivorship through long-term studies of multiple stress factors,” a spokesman said. “These new facilities support two recently hired researchers: Drs. Arathi Seshadri and Julia Fine. These new scientists and associated technical staff are members of the Invasive Species and Pollinator Health Research Unit, whose mission is to develop and transfer integrated biologically based approaches for the management of invasive species and the improvement of pollinator health. The research team collaborates with federal, university, non-governmental and industry partners conducting research to improve honey bee survival and beekeeping sustainability in California and nationwide."
Research leader Paul Pratt of the Invasive Species and Pollinator Health Research Lab will give the welcoming address, followed by the presentation of colors by the Travis Air Force Base Honor Guard.
Among the speakers: Robert Matteri, director of the Pacific West Area, USDA-ARS; Anita Oberbauer, associate dean, UC Davis College of Agricultural and Environmental Sciences; and Kevin Hackett, national program leader, USDA-ARS.
The two new researchers will be introduced, followed by remarks by Darren Cox of Cox Honey of Utah, past president of the American Honey Producers' Association; Jackie Parks-Burris, past president of the California State Beekeepers' Association; and Extension apiculturist Elina Lastro Niño of the UC Davis Department of Entomology and Nematology and the Harry H. Laidlaw Jr. Honey Bee Research Facility. Niño also directs the California Master Beekeeper Program.
The event is open to invited guests. All guests are invited to tour the new facilities following the program. A stakeholder meeting is set from 2:30 to 3:30 p.m. in the Laidlaw bee facility classroom. For more information,contact Platt at firstname.lastname@example.org./span>
Are you ready to celebrate Moth Night at the Bohart Museum of Entomology at the University of California, Davis?
Mark your calendar for 8 p.m. to 11 p.m. on Saturday, July 21.
That's when the Bohart Museum will join forces with National Moth Week, July 21-29, to celebrate the beauty, life cycles and habitats of moths. It's free, open to the public, and family friendly.
The Bohart, located in Room 1124 of the Academic Surge Building, Crocker Lane, is hosting the "Moth Night" both inside and outside the museum. You will see scores of moth and butterfly displays inside. Outside, moth light traps will be set up so you can see what moths are drawn to the blacklighting displays.
The UC Davis event is one of only two public events scheduled in California during the week; the other is in San Mateo County on July 28.
Bohart scientists will be on hand to discuss moths and answer questions. They include three Bohart associates: entomologist Jeff Smith of Rocklin, curator of the the moth and butterfly specimens; and "Moth Man" John DeBenedictis and naturalist and photographer Greg Kareofelas, both of Davis, who will staff the light traps/blacklighting displays. The best time to see the moths in the light traps is later in the evening, closer to 10, according to Lynn Kimsey, director of the museum, and Tabatha Yang, education and outreach coordinator.
"We will focus on colorful moths of the night--night rainbows if you will and the biodiversity of tropical moths," Yang said. A family craft activity is planned. Last year the family craft activity featured making moth-shaped window ornaments resembling stained glass.
Free refreshments--cookies and hot chocolate--will be served. Common Grounds, a Davis coffee shop. will be providing the large containers of hot water for the event.
One of the "oh, wow!" moths is Attacus atlas (Atlas moth), found in the rainsforests of Asia. One of the largest moths in the world, it has a wingspan that can measure 10 to 11 inches.
Last year more than 15 species landed on the blacklighting display. The first moth to arrive was the alfalfa looper moth, Trichopusia ni. The most striking: the grape leaffolder, Desmia funeralis.
Some facts about moths, from the National Moth Week website:
- Moths are among the most diverse and successful organisms on earth.
- Scientists estimate there are 150,000 to more than 500,000 moth species.
- Their colors and patterns are either dazzling or so cryptic that they define camouflage. Shapes and sizes span the gamut from as small as a pinhead to as large as an adult's hand.
- Most moths are nocturnal--others fly like butterflies during the day.
- Finding moths can be as simple as leaving a porch light on and checking it after dark. Serious moth aficionados use special lights and baits to attract them.
The Bohart Museum houses a global collection of nearly eight million specimens. It is also the home of the seventh largest insect collection in North America, and the California Insect Survey, a storehouse of the insect biodiversity. Noted entomologist Richard M. Bohart (1913-2007) founded the museum. It maintains a live "petting zoo," featuring Madagascar hissing cockroaches, walking sticks, tarantulas, and praying mantids. The museum's gift shop, open year around, includes T-shirts, sweatshirts, books, jewelry, posters, insect-collecting equipment and insect-themed candy.
The Bohart Museum's regular hours are from 9 a.m. to noon and 1 to 5 p.m. Mondays through Thursdays. It is closed to the public on Fridays, Saturdays and Sundays and on major holidays. Admission is free.
Although the festival, set from 10 a.m. to 5 p.m. in downtown Woodland, focuses on honey bees--they're the pollinators that produce honey!--you'll see other arthropods there, too, including native bees and spiders.
The Bohart Museum of Entomology at UC Davis will be displaying bee specimens, including sweat bees, leafcutter bees, blue orchard bees, bumble bees, carpenter bees, sunflower bees and others. Directed by Lynn Kimsey, professor of entomology at UC Davis, the insect museum houses some eight million insect specimens, plus a live "petting zoo" (think Madagascar hissing cockroaches, tarantulas, and stick insects) and a year-around gift shop. It's located in Room 1124 of the Academic Surge Building.
Look for spiders, too, at the California Honey Festival. "Interns will be tabling from Heidi Ballard's Education 142 class on environmental education," said Tabatha Yang, the Bohart Museum's education and outreach coordinator, who is assisting with the project. They will be discussing the different hunting techniques of various spiders, including crab spiders, jumping spiders, trapdoor spiders and orbweavers.
The California Honey Festival is a free, family friendly event sponsored by the UC Davis Honey and Pollination Center and the City of Woodland. it will include bee presentations, live music, cooking demonstrations, a beer and wine garden, and a Kids' Zone. You'll learn from world-class bee garden designer and author Kate Frey on what to plant in your garden to attract bees. She and Professor Gretchen LeBuhn of San Francisco State University authored the award-winning book, The Bee Friendly Garden.
Extension apiculturist Elina Lastro Niño, California's state apiculturist, and a member of the UC Davis Department of Entomology and Nematology faculty, will present three "live" bee demonstrations in a circular screened bee tent. Her demonstrations are scheduled for 11:15, 1 p.m. and 3:45 in the bee tent, UC Davis Stage. See complete schedule of events.
Amina Harris, director of the Honey and Pollination Center, says the festival was created in 2017 to cultivate an interest in beekeeping, and to educate the public in support of bees and their keepers. "Bees face many threats today—it is the goal of the festival to help attendees understand the importance of bees to food diversity in the United States."
The California Honey Festival's mission is to promote honey, honey bees and their products, and beekeeping. Through lectures and demonstrations, the crowd can learn about bees and how to keep them healthy. Issues facing the bees include pests, pesticides, diseases, malnutrition, and climate changes.
So, come for the bees. Stay for the native bees and...the spiders. Then next year on March 14 you can celebrate National Save a Spider Day.
The Hammock lab and the Guodong Zhang lab at the University of Massachusetts published exciting research today (April 30) in the Proceedings of the National Academy of Sciences that involves hope for patients with obesity-enhanced colon cancer.
Their research showed that inhibiting an enzyme, soluble epoxide hydrolase--discovered in the Hammock lab--may reduce the risk of obesity-enhanced colon cancer and may offer a therapeutic target to block and treat colonic inflammation.
Co-first authors Weicang Wang and Jianan Zhang of the Zhang lab, and Jun Yang of the Hammock lab/UC Davis Comprehensive Cancer Center, noted that 30 percent of Americans are obese, and these individuals have a 30 to 60 percent higher risk of developing colon cancer. It is the third most common cancer and the second leading cause of cancer-related deaths in the United States. Colon inflammation is an early symptom of cancer.
“But to date, the mechanisms by which obesity increases cancer risks are not well understood, and there are few effective strategies to prevent obesity-enhanced colon cancer," said Zhang, a former postdoctoral researcher in the Hammock lab and now an assistant professor of food science at UMass where he focuses his research on prevention of colonic inflammation (inflammatory bowel disease) and colon cancer. "Our study showed that soluble epoxide hydrolase and its metabolites are over-expressed in colon of obese mice. In addition, we found that pharmacological inhibition or genetic deletion of soluble epoxide hydrolase (sEH) abolishes obesity-induced inflammation and activation of pro-tumorigenic pathways in colon. These results showed that sEH is an essential enzyme involved in obesity-enhanced colonic inflammation and potentially colon cancer, and pharmacological inhibitors of sEH could be novel agents for prevention of these diseases.”
In the study, the 18-member team investigated the roles of sEH in obesity-induced colonic inflammation, which included using two different sEH inhibitors and a knockout mouse genetically modified not to produce sEH. Results proved similar in all cases.
They further conducted another study in both lean and obese mice with experimentally induced colon inflammation and used molecular analyses to follow a pathway called Wnt. About 90 percent of sporadic colorectal cancers have activating mutations within the Wnt pathway. The team found that obesity increases activation of Wnt signaling in the colon, but it can be abolished by the two different inhibitors and the knockout.
“The sEH inhibitor blocked obesity-induced colon inflammation,” said Hammock. “This worked even for mice on high fat diets.”
“Colon inflammation is highly associated with a variety of diseases and the inflammation often progresses to colon cancer,” Hammock said. “Weicang Wang, Guodong Zhang and co-workers have done a meticulous job investigating the biologically active fats including fatty acid diols that are associated with the inflammation. By blocking the production of these diols they were able to block the inflammation.”
“The study was an exciting discovery from lipidomics technique,” said co-first author Jun Yang. “The consistent results from pharmacologic inhibition and genetic knockout (KO) as well as the signaling pathway mechanistic studies all support sEH as a potential treatment for obesity-induced colon inflammation."
Co-author Jun-Yan Liu is already collecting human samples to extend the study, and Hammock pointed out that they hope that the soluble epoxide hydrolase inhibitor will be in human clinical trials this year.
This work, titled “Lipidomic Profiling Reveals Soluble Epoxide Hydrolase as a Therapeutic Target of Obesity-Induced Colonic Inflammation,” drew grant support from the USDA's National Institute for Food and Agriculture; National Institutes of Health's National Institute of Environmental Health Sciences (NIH/NIEHS); NIEHS Superfund Research Program, and the National Natural Science Foundation of China.
The five UC Davis researchers—Bruce Hammock, Jun Yang, Jia Sun, and Sung Hee Hwang and Debin Wan—are all with the Hammock lab/UC Davis Comprehensive Cancer Center.
The UMass researchers, in addition to those listed above: Yuxin Wang, Wiepeng Qi, Haixia Yang, and Professor Yeonhwa Park, Department of Food Science, Katherine Sanidad, Food Science and Molecular and Cellular Biology Graduate Program, and Professor Daeyoung Kim of the Department of Mathematics and Statistics.
Hammock, a member of the National Academy of Sciences and the National Academy of Inventors, directs two major UC Davis programs; the Superfund Program financed by the National Institute of Environmental Health's National Institute of Environmental Health Sciences (NIH-NIEHS); and the NIH Biotechnology Training Program. He began his career reseaching insect pests but switched to human health issues.
To date, the Hammock laboratory has published almost 900 peer-reviewed papers on the sEH enzyme, discovered while Hammock and Sarjeet Gill (now of UC Riverside) were researching insect developmental biology and green insecticides at UC Berkeley. The work, begun in 1969, led to the discovery that many regulatory molecules are controlled as much by degradation as by biosynthesis, Hammock said. These epoxy fatty acid chemical mediators control blood pressure, fibrosis, immunity, tissue growth, and pain and inflammation.
For many years Gill and Hammock were alone in studying this enzyme but today its importance is well recognized in mammalian biology, with more than 17,000 peer-reviewed papers in the area. Hammock credits the NIEHS for supporting research in this area since the 1970s.
A Davis-based company, EicOsis, has received a large grant from the U.S. National Institutes of Health to move inhibitors to the clinic to treat diabetic neuropathic pain. “We are developing a non-opiate analgesic to treat the chronic pain often associated with diabetes and hope to be in human trials over the next 12 months,” said William Schmidt, vice president of clinical development at EicOsis.
