The Pacific Branch of the Entomological Society of America (PBESA) has announced that two distinguished professors and a graduate student from the Department of Entomology and Nematology, University of California, Davis, have won major awards.
Distinguished Professors James R. Carey and Thomas W. Scott, and doctoral candidate Mohammad-Amir Aghaee will be among those honored at PBESA's 99th annual meeting of PBESA, set April 12-15 in Coeur d'Alene, Idaho. PBESA encompasses 11 Western U.S. states, plus several U.S. territories and parts of Canada and Mexico
Carey won the Distinguished Teaching Award and his nomination packet will now advance to the national level. Scott won the C. W. Woodworth Award, the highest honor given by PBESA. Aghaee won the John Henry Comstock Graduate Student Award, the highest graduate student award given by PBESA.
Of note: Scott is the 10th UC Davis-affiliated entomologist to win the Woodworth award. This is the third consecutive year that UC Davis has won the Comstock award (previous recipients were Kelly Hamby and Matan Shelomi) and this is the second consecutive year that UC Davis has won the teaching award (Diane Ullman received the 2014 award and then went on to win the national award).
Carey last year received the 2014 Distinguished Teaching Award from the UC Davis Academic Senate, an honor given to internationally recognized professors who excel at teaching. PBESA singled him out for his technological innovations, creativity and excellence.
“Dr. Carey is not only considered the most technologically innovative and creative classroom teacher on the UC Davis campus, but his expertise is highly regarded throughout the UC statewide system,” wrote nominator Michael Parrella, professor and chair of the UC Davis Department of Entomology and Nematology. “He crafted a groundbreaking model for 21st century instruction, and his presentations are in high demand statewide, nationally and globally. His presentations have taken him from UC Davis to UC Irvine to the University of Alabama, and beyond, including Germany, Korea, Denmark, France and Africa.”
“Dr. Carey uses synergistic strategies to develop video-based learning methods for faculty research programs, professional networks and outreach programs,” Parrella said. “He has developed ‘what-you-need-to-know' videos to increase writing and speaking skills and technical fluency, as well as to understand such subjects as copyright and fair use laws. All are geared for ease of learning and increased knowledge retention.”
Carey last year received the 2014 Distinguished Teaching Award from the UC Davis Academic Senate, an honor given to internationally recognized professors who excel at teaching.
When asked his philosophy of teaching, Carey said: “My philosophy of teaching is inseparable from my philosophy of scholarship. Students need to know the big picture to understand the pixels. They need to zoom in and zoom out so that they can consider the details I present in class in the context of larger conceptual and operational frameworks.” (See more.)
Scott, a noted medical entomologist, is a global authority on dengue and other mosquito-borne diseases. In accepting the award, he will present a 30-minute talk April 13 on “Embracing Complexity: The Path to Improved Public Health Entomology.”
Scott, who has researched mosquito-borne disease for 35 years, is a global authority on the epidemiology of mosquito-borne disease, mosquito ecology, evolution of mosquito-virus interactions, and evaluation of novel products and strategies for mosquito control and disease prevention. Among the top vector biologists in the world, he is recognized as the leading expert in the ecology and epidemiology of dengue, said nominator Michael Parrella, professor and chair of the UC Davis Department of Entomology and Nematology.
Scott is known for his holistic and comprehensive approach in finding solutions to protect the world's population from dengue, a disease that infects some 400 million per year. Some 4 billion people in 128 countries, more than half of the world's population, are at risk for dengue. Currently no vaccine or drug is effective against this life-threatening disease.
Scott's most significant research contributions concern the ecology and epidemiology of dengue:
- Blood feeding behavior, longevity, dispersal, and vector-virus interactions of the mosquito Aedes aegypti;
- Longitudinal cohort studies of spatial and temporal patterns in human dengue virus infection in Peru and Thailand; (dengue research in Peru, Thailand, Puerto Rico and Mexico for the past 25 years)
- Impact of human movement on mosquito contact rates and spatial dimensions of dengue virus transmission; and mathematical and computer simulation modeling of mosquito population biology and mosquito-borne pathogen transmission. (See more.)
Mohammad-Amir Aghaee
Mohammad-Amir Aghaee, a doctoral candidate and researcher in the Larry Godfrey lab, is a fifth year Ph.D. candidate working on rice water weevil management in California rice. He will present a talk on the rice water weevil, Lissorhoptrus oryzophilus. He will be among the six Comstock recipients, all winners from their individual branches, honored at the national ESA meeting, Nov. 15-18, 2015 in Minneapolis, Minn.
“Mohammad took on a very difficult project for his dissertation research,” said Extension entomologist Larry Godfrey, who nominated Aghaee for the award. “His project deals with the most important invertebrate pest of rice in California, the rice water weevil. The challenges arose not only from working in the rice system--wading through mud for hours--but also from working with this insect that cannot be reared in the laboratory and which has one generation per year. Therefore, all the field studies had to be conducted within the short window of time each year.”

Therefore, all the field studies had to be conducted within the short window of time each year.”
Active in ESA, Aghaee captained the UC Davis debate team that won the ESA championship in 2013 and 2014. He anchored the UC Davis debate and Linnean Games teams for four years, from 2011 to 2014. He served on the UC Davis Linnaean Team (the Linnaean Games involve answering entomological questions) that won the PBESA championship in 2012. For four years, Aghaee has participated in the ESA's student 10-minute paper competitions, covering such topics as Lygus bug movements in bush beans, efficacy of Bacillus thuringiensis spp. galleriae against rice water weevil, and preliminary research on winter flooding effectiveness against rice water weevil. He won a first-place President's Award for his winter flood presentation in 2013.
Aghaee received his bachelor's degree in environmental sciences, genetics and plant biology in 2010 from UC Berkeley, with high distinction. He obtained his master's degree in entomology from UC Davis in 2012, and expects to receive his doctorate in December 2015
In his research, Aghaee seeks to develop alternative management options for rice growers as part of his dissertation. “I have examined the use of Bacillus thuringiensis spp. galleriae as a biopesticide for rice water weevil and explored the mechanisms of winter flooding rice fields as a cultural control against weevil larvae. I am currently examining the possible role of silicon augmentation as a means of increasing rice tolerance to weevil damage and the potential threat of Brown marmorated stinkbug (Halyomorpha halys) to California rice.
Aghaee and Godfrey recently published an open-access article appearing in the Journal of Integrated Pest Management that discusses the rice water weevil's life history and invasion biology, as well as management strategies and future directions of research. They told the story of the weevil since it was first identified as a pest in 1881 by C. V. Riley and L. O. Howard. They then discussed reasons why it has been able to spread so rapidly — up to 36 kilometers per year in some cases — which is partly because of its ability to reproduce asexually.
“This invasive ability is aided by a particular and peculiar aspect of this weevil's biology, the fact that a small percentage of the population in its native range reproduces by parthenogenesis,” they wrote.
The most harmful insect pest of rice in the United States, it causes yield losses of up to 25 percent. Adults inflict damage by consuming leaf tissue, and the larvae feed on the roots of rice plants. A native of the southeastern U.S., the rice water weevil invaded Japan in 1976, Korea in 1980, China in 1988, and Italy in 2004. (See more.)
Congratulations to Professors Carey and Scott and doctoral student Mohammad-Amir Aghaee! It's quite an honor to receive these awards. PBESA encompasses 11 U.S. states (Alaska, Arizona, California, Hawaii, Idaho, Montana, Nevada, Oregon, Utah, Washington and Wyoming); several U.S. territories, including American Samoa, Guam and the Northern Mariana Islands; and parts of Canada and Mexico.

They're pests of fruits, vegetable and horticultural crops, including tomatoes, grapes, strawberries and soybeans. They're barely visible to the naked eye, but oh, how disastrous they can be. Some thrips transmit plant diseases, such as the tomato spotted wilt virus.
Enter Professors George Kennedy and Diane Ullman.
Kennedy, the William Neal Reynolds Distinguished Professor of Agriculture at North Carolina State University. Raleigh, N.C., will speak on "Modeling the Epidemiology of Tomato Spotted Wilt: Understanding the Role of Thrips Population Dynamics and Virus Inoculum Sources" from 12:10 to 1 p.m., Wednesday, April 1 in 122 Briggs Hall, as part of the UC Davis Department of Entomology and Nematology's winter seminar series.
Colleague/collaborator DianeUllman will introduce him.
"Effective management of this virus in commercial crop production systems requires an understanding of the factors that determine the timing and magnitude of virus spread. This seminar will discuss the ways in which seasonal weather events influence the dispersal dynamics of vector thrips populations, the abundance of virus inoculum sources in the landscape, and ultimately the timing and magnitude of TSWV spread into susceptible crops. It will further provide an illustration of how efforts to model these relationships improved understanding of the epidemiology of TSWV and led to the development of a TSWV risk prediction tool that is now being used in pest management decision making."
Kennedy, past president of the Entomological Society of America (ESA), holds a bachelor's degree in entomology from Oregon State University and a doctorate in entomology from Cornell University. See his biosketch on the ESA website.
Ullman and Kennedy are among those organizing two consecutive mid-May conferences at the Asilomar Conference Center, Pacific Grove. International scientists, Extension specialists, and agricultural industry professionals will target thrips and insect-vectored pathogens.
The second conference is the Xth International Symposium on Thysanoptera and Tospoviruses, to be held May 16-20. "This meeting is the tenth in a series of international symposia that, over 30 years, have grown to be the dominant vehicle and venue for information exchange between scientists investigating problems related to thrips and tospoviruses around the world," Ullman said. "These symposia have been instrumental in extending knowledge and producing new solutions and innovations in thrips and tospovirus management worldwide, by providing a forum for sharing research findings and integrating fundamental and applied knowledge.
And about those thrips...
The tiny insects pierce hundreds of species of plants, sucking the nutrients and causing billions of dollars in damage to U.S. agricultural crops. As mentioned, they transmit plant viruses in the genus Tospovirus, such as the tomato spotted wilt virus. Read more on the UC IPM website.
“There are 23 additional approved and emerging tospovirus genotypes transmitted by at least 14 thrips species (Thysanoptera: Thripidae),” said Ullman, who has been researching thrips and tospoviruses since 1987.
That's something to think about when you're planting your tomatoes this spring...

Images of arthropods in the public domain that you can download.
Free. For. All.
Noted insect photographer/entomologist Alex Wild, curator of entomology for the Biodiversity Collections, University of Texas at Austin, has launched the "Insects Unlocked" Project, aiming for $8000 over a month-long campaign.
Wild, who received his doctorate in entomology in 2005 from the University of California, Davis, is a professional insect photographer extraordinaire. And, under his mentorship, a team of students in UT's Insect Image Lab "will learn the art and artistry of digital microphotography while capturing images of Texas's smallest wildlife," he explains. They will "create thousands of beautiful, unique, and informative visual works for release into the public domain. The resulting image collection will be open for anyone to use, free of the constraints of traditional copyright."
"Where can you use Insects Unlocked's images?" he asks. "Anywhere you'd like! Web pages, magazine covers, books, billboards, blogs, t-shirts, scientific papers, apps, social media, coffee mug designs, classroom presentations, Wikipedia, and more. Ours are public works and can be used for anything, including commercialization, without the need for advance permission or even credit."
Today he posted on his Facebook page: "I am pleased to report that the Insects Unlocked project to crowd-fund public domain arthropod images is more than 60% funded, not even a week into a month-long campaign. Your support has been generous and unexpected--thanks so much! To celebrate, over the weekend I created some new public domain images for the project, including this 60 image focus-stack of a Brachygastra mellifica Mexican honey wasp (see below). If you'd like to support more images like this, consider contributing at the link: https://hornraiser.utexas.edu/proj…/54e79bbc14bdf7205ddd5ab7
Basically, donations to the program will support several undergraduate students as they learn the UT imaging system and receive training in scientific imaging, entomology, and outreach. As Wild says, "Donations will also improve our processing computers, add cameras and lighting rigs for field use, and offset the costs of web hosting. Our team will start in the summer of 2015, using the 2015-16 academic cycle as a pilot while we evaluate the feasibility of a long term publicly-funded program."
How many images will be in the public domain? "The amount and type of images we produce is proportional to the level of support we receive," Wild says. "Our image lab is located inside the UT insect collection, and we begin with high-magnification captures of curated material, as well as live field photography at the adjoining Brackenridge Field Laboratory. Should we exceed our funding goal, the Insects Unlocked team may be able to mount expeditions to diverse parts of Texas to photograph and video more live insect behavior in the field.
Wild, who studied with major professor/ant specialist Phil Ward at UC Davis, captures amazing images of insects. His work has been published in scientific journals, books, magazines, and newspapers, including the New York Times, National Geographic and Scientific American. He returned to the UC Davis campus in October 2011 to deliver a presentation on "How to Take Better Insect Photographs." His presentation is the most popular of all the UCTV seminar videos posted by the UC Davis Department of Entomology and Nematology. Watch it online.
Wild is enjoying his new position as curator. The collection contains about 500,000 pinned and 500,000 ethanol specimens. "We have one of the world's largest collections of cave arthropods," he said.
You can follow the project on Twitter at @InsectsUnlocked, and view and download the images on Flickr. Wild writes about the project on his Myremocs blog and in his Scientific American blog.
Alex Wild appreciates the generosity of the 75 donors (as of today). But he, too, is generous--exceedingly generous!--with his time and talents that will benefit us all.

Visitors at the annual California Agriculture Day, held Wednesday, March 18 on the west lawn of the State Capitol, made a beeline to the California State Beekeepers' Asssociation (CSBA) booth to see the bees, pocket some honey sticks and talk bees.
Staffing the booth were five beekeepers and Extension apiculturist emeritus Eric Mussen of the UC Davis Department of Entomology and Nematology, who retired last June after 38 years of service, fielded lots of questions.
Bill Cervenka of Bill Cervenka Apariies, Half Moon Bay, provided a bee observation hive. Carlin Jupe of Sacramento, secretary-treasurer of the CSBA, brought along 2000 Honey Stix containing wildflower honey, ordered from Nature's Kick, Salem, Ore.
Each honey stick contained a CSBA message:
- Honey bees are the backbone of agriculture
- They pollinate 1/3 of the human diet
- They pollinate 50 varied U.S. crops worth more than $20 billion
- They pollinate California's $2.5 billion almond production
- They produce $150 million in U.S. honey and beeswax
"I spent quite a bit of time on 'How do I keep bees in a thirty-third floor apartment with no balcony?'" Mussen related. "I sent a number of people to the Sacramento Beekeeping Supply store to find an opening in beginning beekeeping courses. I spent time explaining the bee space and how to keep purchasing wooden ware from the same supplier, so the space would not be violated."
Folks also wanted to know how the drought is impacting the bees. State Senator Jim Nielsen "wanted to know that he kicked up enough of a fuss to get agriculture a place at the water conference table. Up until then, no ag reps were desired."
Eight-year-old Sam Blincoe of Sacramento took a special interest in the bee observation hive, as Mather explained what the bee colony is all about. "He's going to become a beekeeper," she predicted.
The theme, she added, "also reflects the United Nations' declaration of 2015 as the International Year of Soils to increase awareness and understanding of the importance of soil for food security and essential ecosystem functions."
Meanwhile, California Farm Bureau Foundation president Paul Wenger issued this statement today, the first day of spring: "On this first day of spring, we celebrate the agricultural bounty of our nation and especially of California, where a unique combination of climate, soils, water and know-how allows farmers and ranchers to harvest food and farm products every day of the year. While parts of our nation continue to shiver in cold and snow, California provides, thanks to one of only five Mediterranean climates in the world. As we celebrate this bounty, we must also resolve to assure we can sustain it. As California suffers through another year of drought, we must pay particular attention to our state's ability to manage the rain and snow that does fall each winter, to sustain us through dry times. Farm Bureau will continue to press our leaders, at the local, state and national levels, to assure sustainable food production by building new water storage and better managing the entire water system, to ensure California remains the No. 1 agricultural state in the nation."

Ever watched Valley carpenter bees (Xylocopa varipuncta) foraging on salvia?
Native pollinator specialist Robbin Thorp, distinguished professor of entomology at the University of California, Davis, recently noticed a flurry of carpenter bees in the grape-scented sage, Salvia melissodora, in the Department of Entomology and Nematology's bee garden on Bee Biology Road.
Native bee enthusiast Celeste Ets-Hokin of the Bay Area gifted the plant to him. It is now thriving in the department's half-acre bee friendly garden, the Häagen-Dazs Honey Bee Haven. Planted in 2009, the garden is located on Bee Biology Road, next to the Harry H. Laidlaw Jr. Honey Bee Research Facility, west of the central campus.
When carpenter bees forage on the sage, they receive "pollen deposits" or "pollen caps" on their heads. "A perfect placement spot for pollen transfer from flower to flower," Thorp commented. "It also produces a striking orangish patch on the face of the all black bees."
The female Valley carpenter beesare solid black, while the males (which Thorp calls "teddy bear bees"), are green-eyed blonds.
As for the Salvia melissodora, the name "melissodora" originates from the Greek "Melissa" (honey bee) and "odora" (fragrance).
Mark your calendar for Saturday, May 2. That's when the Department of Entomology and Nematology will celebrate the fifth anniversary of the garden installation. Free and open to the public, the open house will take place from 10 a.m. to 2 p.m. UC Davis bee scientists will be there to help you observe and identify the native bees and provide information on honey bees. Download the flier for more information.
Thanks to a generous gift from Häagen-Dazs, the garden came to life during the term of interim department chair, Professor Lynn Kimsey, director of the Bohart Museum of Entomology, who coordinated the entire project.
A Sausalito team--landscape architects Donald Sibbett and Ann F. Baker, interpretative planner Jessica Brainard and exhibit designer Chika Kurotaki--won the design competition. The judges were Professor Kimsey; founding garden manager Missy Borel (now Missy Borel Gable), then of the California Center for Urban Horticulture (CCUH) at UC Davis and now director of the statewide UC Master Gardeners; David Fujino, executive director, CCHU; Aaron Majors, construction department manager, Cagwin & Dorward Landscape Contractors, based in Novato; Diane McIntyre, senior public relations manager, Häagen-Dazs ice cream; Heath Schenker, professor of environmental design, UC Davis; Jacob Voit, sustainability manager and construction project manager, Cagwin and Dorward Landscape Contractors; and Kathy Keatley Garvey, communications specialist, UC Davis Department of Entomology and Nematology.
Others who played a key role in the founding and "look" of the garden included the UC Davis Art/Science Fusion Program, co-founded and co-directed by the duo of entomologist/artist Diane Ullman, professor and former chair of the UC Davis Department of Entomology (now Department of Entomology and Nematology), and self-described "rock artist" Donna Billick. The ceramic mosaic art is the work of UC Davis Entomology 1 students, taught by Ullman and Billick, and artists from the community. Billick's stunning ceramic bee sculpture of a worker bee, "Miss Bee Haven," anchors the garden. Eagle Scout Derek Tully planned, organized and built a state-of-the-art fence around the garden. Later the California chapter of the Daughters of the America Revolution provided a much-welcomed donation. (Read more about the history of the bee garden here). Chris Casey succeeded Melissa Borel as the manager of garden.
Now five years have come and gone, and generations of bees have come and gone. Life is good.
