The California Master Beekeeper Program (CAMBP), directed by Extension apiculturist Elina Lastro Niño of the UC 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 husbandry 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 email@example.com.
Rebecca Godwin won first in the poster competition for her research on trapdoor spiders and Lacie Newton won second for her oral presentation on species delimitation. Their major professor, Jason Bond, is the department's Evert and Marion Schlinger Endowed Chair in Insect Systematics.
Godwin titled her work, “Revision of New World Ummidia (Mygalomorphae, Halonoproctidae)”: Her abstract: “Ummidia is a historically taxonomically difficult group of spiders belonging to the infraorder Mygalomorphae, one of the three main lineages recognized within spiders. Mygalomorph life history and their incredibly cryptic appearance make them difficult to identify, as a result they are frequently overlooked by spider systematists. Ummidia Thorell 1875 is a wide-ranging genus of trapdoor spider found both in the Mediterranean region of the Old World and in the New World from the eastern United States south to Brazil. Taxonomic work on New World Ummidia is sparse outside of original descriptions, the most recent of which are over half a century old."
"I am revising the genus Ummidia in the Nearctic region. I have approached this taxonomic problem by examining approximately 700 specimens of Ummidia from various collections (American Museum of Natural History, Museum of Comparative Zoology, Florida State Collection of Arthropods, California Academy of Sciences, and Auburn University Museum of Natural History). Examination of museum material has seemingly confirmed the undescribed diversity of Ummidia; preliminary estimates of New World species ranging between 50 and 60, with particularly high amounts of diversity in the Florida and Virginia. This study, along with many others conducted utilizing museum collections, is indicative of the importance of natural history collections and their usefulness in discovering unknown biodiversity.”
"Previous research by Hendrixson and Bond (2005) described a new sympatric species Antrodiaetus microunicolor in the A. unicolor species complex using morphological criteria (i.e. size and setal character differences) and behavioral criteria (non-overlapping mating seasons). Subsequently, they used two molecular markers COI and 28S and discovered that A. unicolor is paraphyletic with respect to A. microunicolor. To further delineate this species complex, we implement the cohesion species concept and employ multiple lines of evidence for testing genetic exchangeability and ecological interchangeability. Our integrative approach includes extensively sampling homologous loci across the genome using a version of RADseq called 3RAD, assessing population structure across their geographic range, and evaluating ecological similarity by niche-based distribution modeling. Based on our analyses, we conclude that this species complex has two or three species in addition to A. microunicolor.”
Godwin holds two degrees from Auburn University: her bachelor's degree in zoology in 2004, and her master's degree in wetland biology in 2011. She began her doctoral studies at Auburn University in 2014, and transferred to UC Davis when Bond accepted the UC Davis position in 2018.
Godwin's research interests include taxonomy, systematics, and phylogreography of trapdoor spiders, as well as effective science communication and increasing general science literacy.
Newton received her bachelor of science degree from Millsaps College, Jackson, Miss., in 2016, and then joined the Auburn University doctoral program. Like Godwin, she transferred to UC Davis with her major professor in 2018. Newton served as an undergraduate teaching assistant at Millsaps College for “Introduction to Cell Biology” and “General Zoology,” and as a graduate teaching assistant in “Introduction to Biology” at Auburn University.
Newton now serves as a graduate teaching assistant at UC Davis for “Introduction to Biology: Biodiversity and the Tree of Life.” She won the 2019-2020 George H. Vansell Scholarship, UC Davis. Her research interests include systematics, species delimitation, and phylogeography of spiders; phylogenetics; comparative transcriptomics of troglophilic and troglobitic spiders; cave biology and conservation.
Both Godwin and Newton volunteer at the Bohart Museum of Entomology's programs on spiders and at the campuswide UC Davis Biodiversity Museum Day.
Bond joined the UC Davis faculty after a seven-year academic career at Auburn University, Ala. He served as professor of biology and chair of the Department of Biological Sciences from January 2016 to July 2018, and as curator of arachnids and myriapods (centipedes, millipedes, and related animals) at the Auburn University Museum of Natural History, from August 2011 to July 2018.
The 16th annual Bruce Hammock Lab Water Balloon Battle--known as "Bruce's Big Balloon Battle at Briggs" or "15 Minutes of Aim"--is set for 3 p.m., Friday, July 12 on the Briggs Hall lawn.
The event will take place on the northwest side of Briggs on the lawn between Briggs and the fire department--"the one still green," said coordinator Christopher Morisseau, a researcher in the Hammock lab. (The traditional site is being prepared for planting.)
Participants will fill 2000 balloons, starting at 1 p.m. on the grass by the loading dock. Morisseau said the policy is "no filling,no throwing" or "bring your own balloons."
It is open to all who want to get wet, and children and spouses are always welcome.
Last year water balloons, water guns, super sprayers, and buckets prevailed in the international soakfest. Twenty-eight researchers in the Hammock lab from seven countries participated: the United Stares, China, France, Ukraine, Lebanon, Japan and Korea. They included postdoctoral scholars, researchers, graduate students, visiting scholars, visiting graduate students, visiting summer students, short-term visiting scholars and student interns.
Hammock, a UC Davis distinguished professor who holds a joint appointment with the UC Davis Department of Entomology and the UC Davis Comprehensive Cancer Center, hosts the annual event in mid-July when triple-digit temperatures strike the campus. It's an opportunity for the lab members--who work hard throughout the year and play hard for 15 minutes--to engage in a little fun and camaraderie. The thirsty lawn benefits, too.
Hammock, trained as a entomologist, chemist and toxicologist--and who now focuses his research on human health, is recognized for his work on using natural chemical mediators to control inflammation and intractable pain. He co-discovered the soluble epoxide hydrolase, and many of his more than 1100 publications and patents are on the P450 branch of the arachidonate cascade where the soluble epoxide hydrolase (sEH) degrades natural analgesic and anti-inflammatory compounds.
Hammock, an alumnus of UC Berkeley with a doctorate in entomology, joined the UC Davis faculty in 1980. He is the founding director (1987-present) of the UC Davis NIEHS (National Institute of Environmental Health Sciences) Superfund Research Program and is a founding member (1990-present) of the UC Davis Comprehensive Cancer Center. He has directed the UC Davis NIH/NIEHS Combined Analytical Laboratory for 25 years.
Highly honored by his peers, Hammock is a fellow of the National Academy of Inventors, which honors academic invention and encourages translations of inventions to benefit society. He is a member of the U.S. National Academy of Sciences, a fellow of the Entomological Society of America, and the recipient of the Bernard B. Brodie Award in Drug Metabolism, sponsored by the America Society for Pharmacology and Experimental Therapeutics. He is the first McGiff Memorial Awardee in Lipid Biochemistry. The Eicosanoid Research Foundation recently honored him for work on oxidized lipids.

Shahid Masood Siddique has never met a plant parasitic nematode he didn't like--to study, that is.
Plant-parasitic nematodes are microscopic worms that extract water and nutrients from such host plants as wheat, soybeans, sugar beets and bananas.
“They're one of the most destructive agricultural pests,” says Siddique, an assistant professor with the UC Davis Department of Entomology and Nematology. “The agricultural losses due to plant-parasitic nematodes reach an estimated $80 billion. The high impact of plant parasitic nematodes in economically important crops is not only due to the direct damage but also because of the role of some species as virus vectors.”
“In fact, a recent expert-based assessment of crop health lists nematodes among the most damaging pests and pathogens in different crops. In particular for soybeans, nematodes are the most damaging pests in the United States and around the world.”
Siddique, who joined the UC Davis faculty in March after serving as a research group leader for several years at the University of Bonn, Germany, says nematodes are troubling in other ways as well. “Although nematode-resistance varieties are available for various crops, there is an emergence of resistant-breaking population throughout the world. An example is the recent arrival of peach root-knot nematode in California, which has the potential to seriously harm many of region's important crops including almonds, peaches, eggplants, sugar beets and cucumber.”
Siddique was among a team of scientists from Bonn University and University of Missouri, who demonstrated the ability of parasitic nematodes to synthesize and secrete a functional plant hormone to manipulate the host system and establish a long-term parasitic interaction. PNAS published the research in August 2015. In a subsequent article headlined “Researchers Discover Key Link in Understanding Billion-Dollar Pests in Agriculture,” Science Daily called nematodes “a huge threat to agriculture, causing billions in crop losses every year …The discovery will help to develop crop plants that feature enhanced protection against this type of parasites.”
Born and reared in Multan, Pakistan, Siddique received two degrees in Multan: his bachelor of science degree from the Government College Bosan Road in 2001 and his master's degree in botany from the Bahauddin Zakariya University in 2004. Then it was off to Vienna, Austria to receive his doctorate in 2009 in agriculture and biotechnology from the University of Natural Resources and Life Sciences.
What sparked his interest in nematology? While studying for his masters, he developed a keen interest in molecular biology and biotechnology. For his doctorate, he sought a lab where “I could do my PhD and learn more about cell and molecular biology.” He found that opportunity with Florian Grundler, a professor at the University of Natural Resources and Life Sciences (BOKU), Vienna, Austria.
“His group was working on understanding the molecular aspects of plant-nematode interaction,” Siddique recalled. “In particular, they were using microarrays to study the changes in gene expression in plants upon nematode infection. I found the work very interesting and joined his lab.”
Nematodes did not immediately trigger his interest. “They have a complicated life cycle and infection pattern,” he points out. “Also, it is not yet possible to genetically transform plant-parasitic nematodes. So, I was mostly focusing on plants, which are more amenable to genetic manipulations. Then I gradually started to realize that how fascinating it is to work with nematodes, how they have mastered the ability to manipulate the defense and developmental pathways of their host.”
By the time he completed his doctorate, “I was completely infected by nematodes.” He still is.
What drew him to UC Davis? “High academic reputation in field of agriculture was the main factor that drew me to UC Davis,” Siddique says. “Ethnic diversity and liberal culture of golden state are some of the other factors that contributed to my decision to move to UC Davis.”
“For the next six months, I will be focusing on establishing a state-of-the art nematology lab here at UC Davis. This includes buying equipment, hiring the staff, establishing the protocol, and multiplying the nematode culture. In terms of research, my mid-term goal is understanding the plant immune responses to nematode infections. In long-term, I would like to use this knowledge to produce durable and broad-spectrum resistance in crops.”
“Another area where I will be focusing is development of molecular diagnostic tools for plant-parasitic nematodes from soil,” Siddique says. “I will be particularly focusing on nematodes that are relevant to California agriculture. Lastly, I am highly interested in understanding the mechanism of biocontrol of plant-parasitic nematodes. I expect that this will help in understanding why application of microbial biocontrol is so inconsistent.”
Siddique describes himself as “a result-oriented person and I am comfortable leading a large research team. At the same time, I like to delegate the responsibilities. My working style is collaborative and I believe on open and frank communication.”
In his leisure time, he enjoys cooking, outdoor adventures and watching documentaries. What would people be surprised to know about him? “I am an introvert,” he says. “A couple of other things: I like super spicy food and my favorite game is cricket. And oh, yes, I don't like ice-cold water.”
Siddique is currently seeking “undergraduate and graduate students to work on a number of exciting projects.”
“California is a beautiful place to live,” Siddique says, “and Davis is a perfect place to work on nematodes. So, for those interested in working with nematodes, drop me an email at email@example.com.”

Those are a few of the activities or calendar items newly announced by the Bohart Museum of Entomology.
Moth Night. The Bohart will celebrate National Moth Night: Exploring Night Time Nature on Saturday, Aug. 3, instead of in July. The event, free and family friendly, will take place from 8 to 11 p.m. Visitors can view the Bohart's world-class collection of moths, make a craft, and search for moths outside with experts. Scientists will set up a blacklight to draw night-flying insects. The set-up includes a white sheet that's illuminated by a generator-powered ultraviolet (UV) light.
Last year Bohart associate and "Moth Man" John De Benedictis listed the species, by family, sighted at Moth Night. Among them
- NOCTUIDAE: Spodoptera exigua (Beet Armyworm Moth), Proxenus sp. (probably P. mindara)
- GEOMETRIDAE: Prochoerodestruxaliata
- PYRALIDAE: Ehestiodesgilvescentella
- TORTRICIDAE: Cydia latiferreana (Filbertworm Moth), Grapholita prunivora (Lesser Appleworm Moth)
- GELECHIIDAE: Leucogniella sp. (probably L. distincta)
- TINEDAE: Oinophila v-flava
- ACROLOPHIDAE: Amydria sp. (cannot tell genus or species without dissecting. Likely Pseudopsalta confusella.)
Lepidopterists' Society Meeting. The Bohart Museum will be closed to the public July 8-12 to accommodate the 68th annual meeting of the Lepidopterists' Society. The Bohart Museum, to host the conference, maintains the seventh largest insect collection in North America with more than eight million specimens. It is also the home of the California Insect Survey.
New Summer Hours. The Bohart Museum will be closed in the mornings to walk-in visitors due to scheduled tours and outreach events, announced Tabatha Yang, education and outreach coordinator. The insect museum will be open to visitors from 1 to 5 p.m., Mondays through Thursdays "and we are offering a scavenger hunt."
Wednesday Walk-Ins. "On Wednesdays, starting July 3 at 2:30 p.m. and 3:30 p.m., we will have casual 30-minute tours for walk-in visitors," Yang said. "No reservations are required. All of these events are free to the public, but donations are suggested."
Directed by Lynn Kimsey, UC Davis professor of entomology, the insect museum is located in Room 1124 of the Academic Surge Building on Crocker Lane. The Bohart also houses a gift shop and a live "petting zoo," comprised of Madagascar hissing cockroaches, walking sticks and tarantulas.
