The UC Davis Department of Entomology and Nematology's seminar on Wednesday, Feb. 26 will feature six “Faculty Flash Talks” on topics ranging from honey bees to tsetse flies to digger bees to trapdoor spiders to fruit flies.
The seminar, set from 4:10 to 5 p.m. in 122 Briggs Hall, will include Joanna Chiu, Jason Bond, Geoffrey Attardo, Rachel Vannette, Julia Fine, and Arathi Seshadri.
Associate professor Joanna Chiu, vice chair of the department, will present “results from a project in which we study the mechanisms by which insects sense environmental changes (temperature and photoperiod) to regulate their seasonal physiology. Our lab has identified a protein that can track seasonal changes in temperature and photoperiod to promote winter physiology. Without this protein, insects don't know winter is coming!”
Her laboratory research interests include molecular genetics of animal behavior, Circadian rhythm biology, and posttranslational regulation of proteins.
Capsule information:
Jason Bond, Schlinger Chair in Insect Systematics, is a global expert on spiders. His research interests include systematics, taxonomy, and evolution of terrestrial arthropods with an emphasis on arachnids and myriapods. "We employ molecular, morphological, and ecological approaches to study questions related to evolutionary diversification at multiple hierarchical levels (populations – higher taxa)," he says. (See recent grant.)
Geoffrey Attardo, a medical entomologist/geneticist, focuses his research on insect disease vectors, insect reproduction, vector/parasite interactions, reproductive physiology, male seminal secretions, symbiosis, lactation, nutrition, lipid metabolism, transcriptional regulation, comparative genomics, transcriptomics, proteomics and metabolomics. His research on tsetse flies was recently featured on KQED's Deep Look (see news story on Deep Look). (See news story on landmark research.)
Rachel Vannette, community ecologist and assistant professor who coordinates the department's seminars, says: "All plants are colonized by microorganisms that influence plant traits and interactions with other species, including insects that consume or pollinate plants. I am interested in the basic and applied aspects of microbial contributions to the interaction between plants and insects. I also use these systems to answer basic ecological questions, such as what mechanisms influence plant biodiversity and trait evolution." (See recent research)
Arathi Seshadri and Julia Fine, who recently joined the USDA-ARS lab on Bee Biology Road, UC Davis, aim to improve honey bee survival and beekeeping sustainability in California and nationwide. They collaborate with federal, university, non-governmental and industry partners. (See news story on opening of the facility.)
Seshadri, a pollination biologist with expertise in honey bee behavior and plant reproductive strategies, is working with beekeepers and farmer stakeholders to develop projects aimed at finding solutions to the ongoing pollination challenges. Also trained as an evolutionary biologist, she has applied principles of plant-pollinator mutualism, specifically the impact of phytochemicals in pollen and nectar on honey bee health and colony performance. Her contributions to pollinator conservation include enhancing the sustainability of all pollinators, including native bees on farms and urban areas. She also has expertise in agroecosystem-based approaches and citizen science programs to promote pollinator diversity and abundance.
Fine, an entomologist with expertise in insect toxicology, honey bee physiology, reproduction and development, focuses her research on identifying how stressors impact honey bee behavior, health and fecundity. She uses both established and novel laboratory techniques. Her previous projects involved investigating how agrochemical and viral stressors interact to affect the development and survival of honey bee brood and how nutritional stress affects honey bee queen fecundity. In engaging with beekeepers and growers, Fine is researching how realistic biotic and abiotic stressors affect honey bee reproduction, longevity and pollination services, and she is identifying techniques and strategies to overcome these effects.
The seminar is open to all interested persons. For more information, contact Vannette at rlvannette@ucdavis.edu.

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.
