The UC Davis Departmentof Entomology and Nematology has scheduled a fifth anniversary celebration of its bee garden on Saturday, May 2.
It's difficult to believe that the Häagen-Dazs Honey Bee Haven is five years old. But it is, and the event will take place from 10 a.m. to 2 p.m.
The half-acre bee garden, planted in the fall of 2009, is located on Bee Biology Road next to the Harry H. Laidlaw Jr. Honey Bee Research Facility, west of the central campus. A public ceremony will be held from 10:30 to 11:30 a.m.
Michael Parrella, professor and chair of the department, will welcome the crowd at 10:30 a.m. Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology, was the interim chair of the department and directed and organized the installation of the garden. It was planted in 2009, thanks to a generous donation from Häagen-Dazs. More than 50 percent of their ice cream flavors depend on pollination.
Raj Brahmbhatt, associate brand manager of Häagen-Dazs Ice Cream at Nestle USA, Dreyer's Ice Cream company, will speak at 10:50 a.m. on “What the Haven Means to Us.”
Christine Casey, manager of the haven, will discuss “What Your Donations Mean to the Haven” at 11:15.
What can you do in the bee garden? Walk the paths. Admire the flowers. Admire the pollinators. Learn how to observe and identify bees, what to plant to help bees, and how to use native bee houses. There also will be beekeeping demonstrations and garden tours.
The garden is open to the public from dawn to dusk every day. Admission is free. Tours (a nominal fee is charged) can be arranged with Casey at cacasey@ucdavis.edu. To book a tour, access the website and click on "Visit Us."
The design is the work of a Sausalito team--landscape architects Donald Sibbett and Ann F. Baker, interpretative planner Jessica Brainard and exhibit designer Chika Kurotak--the winners of the international design competition.
Read more about the garden here! How it all began, who the founding manager was and the honor she and the 19 volunteer gardeners received, and who built the state-of-the-art fence around the garden.
We remember when it was an open field with jack rabbits bounding through the tall grass and red-tailed hawks circling above. The rabbits still bound (but not inside the garden) and the hawks still circle looking for prey.

UC Davis entomology doctoral student Stacy Hishinuma has received and accepted a position in the USDA Pathways Internship Program with the Region 5 field office of the USDA Forest Service, San Bernardino.
Hishinuma studies the walnut twig beetle, Pityophthorus juglandis, which in association with a newly described fungus, Geosmithia morbida, causes thousand cankers disease (TCD) of walnut and butternut trees.
The walnut twig beetle is believed to be native to Arizona, California, New Mexico and Mexico. In 2006, plant pathologist Ned Tisserat and entomologist Whitney Cranshaw of Colorado State University identified the pathogen in declining black walnut trees in central Colorado. The disease has now spread east of the Mississippi to states in the heart of the valuable black walnut timberlands. Most recently it was reported from Indiana. Latest collection records show that the beetle and pathogen are now known from nine states in the western United States and seven states in the eastern USA. In 2013 the disease was also reported in Italy marking the first time that it occurred in Europe.
Hishinuma works with major professor Mary Louise Flint and is co-advised by chemical ecologist and forest entomologist Steve Seybold of the Pacific Southwest Research Station, USDA Forest Service, Davis, an affiliate of the department. Flint is an Extension specialist emeritus with the UC Davis Department of Entomology and Nematology and a former associate director with the UC Integrated Pest Management Program.
“USDA will provide some financial support during the end stages of her Ph.D. thesis, in exchange for 320-640 hours of work and training over the next 14 months,” said Seybold. Then, in June 2016 her position will be converted to that of a permanent entomologist with the USDA Forest Service office in San Bernardino after she has completed her thesis. She will be responsible for forest insect survey, detection, and management on four national forests in southern California ranging from San Diego to Monterey counties.
“The highly competitive internship and guaranteed position are a credit to her and her achievements,” Seybold said.
Seybold and Flint assisted her in developing the internship, as did Richard “Rick” Bostock, UC Davis professor of plant pathology.
Hishinuma won the 2013 Western Forest Insect Work Conference Memorial Scholarship for her research on TCD and presented her work at group's 65th annual conference, held March 31-April 3, 2014 in Sacramento. She also received two scholarships from the California Garden Clubs, Inc. (CGCI) and a McBeth Memorial Scholarship to support her research on TCD.
Seybold's research group has led the effort to characterize the disease in California and to develop a nationwide detection program for the beetle. They recently published two papers in the journal PLOS ONE that characterize the genetic diversity and invasion patterns of both the pathogenic fungus and the beetle in the United States. Scientists believe that TCD occurs only on walnut, butternut, and wingnut, but it is most damaging to native black walnuts, Juglans californica, J. hindsii, and J. nigra although the disease has been recorded on at least 10 species of walnuts or their hybrids in California. Often the first symptoms of TCD are flagging and yellowing leaves and branch dieback, Seybold said. Affected branches show sap staining and pinhole-sized beetle holes. Beneath the surface are dark stains caused by the funguhe news is startling, but not totally unexpected.

As of April 6, the former San Diego resident is the National Thysanoptera Taxonomist with the National Identification Services (NIS) at the Systematic Entomology Laboratory (SEL) in Beltsville, MD.
Specifically, her position is with the National Identification Services (NIS) of the Plant Protection and Quarantine (PPQ) program of USDA's Animal and Plant Health Inspection Service (APHIS) or what USDA officials refer to as "APHIS PPQ NIS." The Thysanoptera collection of the Systematic Entomology Laboratory (SEL) is housed with USDA's Agricultural Research Service (ARS).
“I love my work,” she said, “and I love my favorite insect, thrips.”
Thrips are tiny insects that cause billions worth of damage annually to U.S. agricultural crops. Barely visible to the naked eye, they heavily damage fruits, vegetable and horticultural crops, so much so that they can—and do--pose a biosecurity threat. In 1996, Cuba's Fidel Castro accused the United States of aerially releasing Thrips palmi over potato fields.
“Of the more than 5000 species of thrips known in the world, some are serious pests, and some are beneficial as pollinators and predators,” O'Donnell said. “Some thrips transmit plant diseases, such as the tomato spotted wilt virus and the Impatients necrotic spot viruses.”
“To monitor agricultural crops effectively, it's important to be able to identify them, but it's difficult to do so without understanding thrips taxonomy and identification,” O'Donnell said. “Thrips are so small—one millimeter long or less--that they're like a speck. Inspectors see larvae, eggs and adults on plant material coming in. It's difficult to separate species at the life stage of eggs, larvae and adult males.”
“There were many times I was doubtful that I could continue to meet the demands of my chosen field,” O'Donnell said, crediting her family, friends and UC Davis scientists with offering her the support she needed to complete her education.
O'Donnell holds three degrees from UC Davis: a bachelor's in agricultural systems and the environment (1997), a master's degree in plant protection and pest management (2000) and a doctorate in entomology (2007).
After receiving her doctorate, she joined the USDA as “the co-lateral Thysanoptera specialist, USDA-APHIS-PPQ,” west of the Mississippi. That is, she was a key thrips specialist for the Animal and Plant Health Inspection Service's Plant Protection and Quarantine Program. Her work involved detecting, identifying and intercepting thrips and other pests arriving at U.S. ports from around the world.
Her major professor Diane Ullman, a professor in the UC Davis Department of Entomology and Nematology, describes her as "a tremendously talented biologist and she holds a real fascination for thrips, their classification, host relationships and biology."
"She will do a fantastic job in this position, which will be important to the global community studying thrips and trying to develop management strategies," Ullman told us.
Read more about Cheryle O'Donnell here. She offers good advice to prospective graduate students in encouraging them to follow their dreams: "Focus on your goals, never deviate from those goals, and never allow obstacles to get in the way,” she advises. "It is a difficult and challenging path you have chosen but it will be worth all the hard work. The UC Davis community, the ‘village' which supports you, is an experience you will never forget and the payoff will be great throughout your life.”
Meanwhile, O'Donnell is anticipating two mid-May thrips conferences at the Asilomar Conference Center, Pacific Grove. One of the key organizers is Professor Ullman. See more information.

What a grand event!
When the University of California, Davis held its annual campus "Take Your Daughters (And Sons) to Work" Day today (April 23), the participants met one-on-one with entomologists, firefighters, physicians, plant specialists, veterinarians and scores of others in the UC Davis workforce.
It was one big open house.
At the Bohart Museum of Entomology, children's author S.S. Dudley (also known as retired scientist Steve Stoddard of medical entomologist Thomas Scott's lab in the UC Davis Department of Entomology and Nematology), entertained the crowd by talking about the places he's been, the insects he's seen and the people he's met. He is the author of “Butterfly Wish” and “Elf Hills.”
Joel Fuerte, 6, of Woodland, whose mother Gabriela "Gabby" Sanchez Fuerte, works for the School of Education, listened wide-eyed.
Joel then walked over to the live "petting zoo" and held walking sticks and a rose-haired tarantula named Peaches. Little Roxanne Bell, 7, whose mother Jenna works at the Mondavi Center, said that Peaches "tickled" her. Her expression? Priceless!
Meanwhile, Tabatha Yang, education and public outreach coordinator, led tours of the museum, which houses nearly eight million insects.
"Take Your Daughters (And Sons) to Work" goes by the name of TODS, but that doesn't began to explain what it's all about. It's more than just a career day. Officials say "it not only exposes girls and boys to what a parent or mentor does during his/her workday, but shows children the value of their education and provides an opportunity to share how they envision their future and begin steps toward their goals in a hands-on and interactive environment."
Yes, it does.
Maybe some day little Joel Fuerte will become a children's author and little Roxanne Bell, an entomologist. Or vice versa! Or, maybe they can do both, and follow the career path of Steve Stoddard, aka S. S. Dudley.

Overhead in the lady's restroom of a restaurant at the Sausalito marina:
Mother to daughter: "There's a lady in here."
Daughter: "A lady? Well, why wouldn't there be a lady in here? This is a lady's restroom."
Mother: "Look right over there, on the wall."
Indeed, there was a "lady" in the lady's restroom: a lady beetle. Family Coccinellidae. The damsel in distress was crawling up and down the cement wall searching for something it couldn't find. An escape route!
So, I picked up the domed-wonder and transported it from Marin County to our Solano County home. I deposited the little traveler on an Iceland poppy.
The lady beetle perked up, checked out its surroundings, and began exploring.
Ah, aphids!
Happy Earth Day!
