Scott, internationally known for his work on the ecology and epidemiology of dengue, received the award "for his outstanding contributions to the study of mosquito ecology, evolution of mosquito-virus interactions, epidemiology of mosquito-borne disease and evaluation of novel products and strategies for mosquito control and disease prevention."
He focuses his work on contributing to improved public health in the United States and in the developing world, where resources are inadequate and help is desperately needed.
The coveted ASTMH award memorializes parasitologist-entomologist Harry Hoogstraal (1917-1986), a global authority on ticks and tick-borne diseases.
Scott, who joined the UC Davis faculty in 1996, received his bachelor and master's degrees from Bowling Green (Ohio) State University, and his doctorate in ecology in 1981 from Pennsylvania State University. He did postdoctoral research in epidemiology at Yale University School of Medicine's Arbovirus Research Unit, part of the Department of Epidemiology and Public Health.
Scott served on the faculty of the Department of Entomology, University of Maryland, from 1983 to 1996 before joining the UC Davis entomology faculty as a professor of entomology and director of the Vector-Borne Disease Laboratory. He was acting director of the UC Davis Center for Vector-Borne Research from 1996 to 1999, and directed the UC Davis Arbovirus Research Unit from 2001 to 2003. He served as vice chair of the Department of Entomology from 2006 to 2008.
In 2014, Scott was selected a “distinguished professor,” an honorary title bestowed by the provost “to recognize outstanding faculty in the professional series who have achieved the highest level of scholarship.”
Highly honored by his peers, Scott is a fellow of three organizations: American Society of Tropical Medicine and Hygiene (2014), Entomological Society of America (2010), and the American Association for the Advancement of Science (2008). In 2015, he won the Charles W. Woodworth Award, the highest honor awarded by the Pacific Branch of the Entomological Society of America.
Scott is the fifth medical entomologist from UC Davis to receive the Harry Hoogstraal Award since it was first presented in 1987. Other UC Davis recipients:
- 2012: William Reisen, director of the Center for Vectorborne Diseases (CVEC)
- 2007: Bruce Eldridge, former director of the statewide UC Mosquito Research Program and emeritus professor of entomology at UC Davis
- 2005: Robert Washino, emeritus professor and former chair of the UC Davis Department of Entomology
- 2004: John Edman, former director of CVEC and emeritus professor of entomology

The award-winning UC Berkeley-UC Davis Linnaean Games Team will vie for the national championship at the Entomological Society of America's annual meeting, set Nov. 11-14 in the Vancouver Convention Center, Vancouver, B.C.
The Linnaean Games, launched in 1983, are lively question-and-answer, college bowl-style competitions on entomological facts and played by winners of the ESA branch competitions. The teams score points by correctly answering random questions.
The UC Berkeley-UC Davis team is comprised of captain Ralph Washington Jr., a UC Davis entomology graduate who is studying public policy at UC Berkeley; UC Davis doctoral students Brendon Boudinot, Jill Oberski and Zachary Griebenow, all of Phil Ward lab, specializing in ants; and UC Davis doctoral student Emily Bick of the Christian Nansen lab, a lab that specializes in insect ecology, integrated pest management and remote sensing.
The UC Davis Linnaean Games Team, captained by Washington, won the national championship twice, defeating the University of Georgia in 2016 and the University of Florida in 2015. Boudinot served on both championship teams, and Bick, the 2016 team.
Last year UC Davis did not compete. Texas A&M won the national championship, with Ohio State University finishing second.
The national preliminaries will begin at noon Sunday, Nov. 11 while the finals will get underway at 5 p.m. on Tuesday, Nov. 13. Members of the winning team will each receive a gold medal and and a plaque for the team's department.
The UC Berkeley-UC Davis team won the regional championship at the Linnaean Games hosted by the Pacific Branch of ESA at its meeting June 10-13 in Reno. They defeated Washington State University in a sudden death overtime to win the title.
Among the questions asked at the regional competition:
Question: Name the fungal agent that grows naturally in soils throughout the world and causes white muscardine disease and is commercially packaged as a biological insecticide for the control of termites, whiteflies, and other insect pests?
Answer: Beauveria bassiana
Question: Name the process through which spiders use silk to fly and disperse.
Answer: Ballooning.
Question: Where are you most likely to encounter a rheophilic insect?
Answer: In moving streams.
Theme of the ESA meeting is “Sharing Insect Science Globally.” This year it is a joint meeting with the Entomological Societies of Canada and British Columbia.
The 7000-member ESA, founded in 1889, is the world's largest organization serving the professional and scientific needs of entomologists and individuals in related disciplines. It is affiliated with educational institutions, health agencies, private industry, and government.

Entomology Today, published by ESA, posted a preview of the 2018 Linnaean Games. Author Emily Justus, a graduate student in entomology, Ohio State University, interview some of the participants. She wrote: "Another common thread between teams is that they believe having a well-rounded team gives them an edge. Zach Griebenow, a member of UC Davis/Berkeley team, attributes their success to the members of his team being broadly knowledgeable, and he says he believes that all successful teams have this in common."

A new display, designed and coordinated by Bohart associate and UC Davis biological sciences graduate Emma Cluff, showcases stick insects and insect digestion. A research grant donated by Brian Johnson, associate professor of entomology, funded the project.
“I have always thought stick insects were pretty amazing,” said Cluff, who worked on the project over a six-month period. “I loved making the display visually catching as well as informative. I spent a lot of time reading papers and communicating with graduate students who worked with Brian Johnson, and I enjoyed figuring out how to translate their science into terms that the public would find accessible.” The Johnson lab studies the genetics, behavior, evolution, and health of honey bees and currently focuses on the evolution and genetic basis of social behavior using comparative and functional genomics.
Stick insects, most abundant in the tropics and subtropics, belong to the order Phasmatodea and are found on all continents except Antarctica. They derive their name from the ancient Greek “Phasma,” meaning an apparition or phantom, referring to their resemblance to sticks or leaves.
The finished project, mounted on a wall, includes a wood sculpture of a stick insect by Leo Huitt of Woodland, and illustrations by UC Davis entomology student Karissa Merritt, who drew the anterior midgut, Malpighian tubules, crop and hindgut. The display also includes stick insect facts, with lift off tabs.
“People seem surprised that we know so much about stick insect digestion,” Cluff commented. “Visitors have also commented on how incredible it is that a fairly complex digestive system can fit in such a slender organism.”
In her display, Cluff explains cellulose and why it is difficult to digest. She defines cellulose as “a molecule made of linked sugars. It is found in plants and forms plant cell walls. This moleculre provides the rigid structure in plants, like stems and wood (this means that wood is made mostly of sugar!)”
Why is it difficult to digest? “Cellulose has a very stable structure and forms strong fibrous strands. Because of this, animals need enzymes (proteins which enable chemical reactions) to break the cellulose apart into sugars.”
This was her first experience designing an exhibit. “It was a really wonderful experience,” she said.
“Emma is very talented and I would really like to see her continue doing science outreach,” said Lynn Kimsey, director of the Bohart Museum and professor of entomology at UC Davis.
Cluff, from Turlock, plans to attend graduate school and become a marine biologist. “I love marine bio and I am also passionate about education so I would like to somehow combine the two. I always loved marine science as a kid, and taking a research course at Bodega Bay re-inspired me. I think marine science is so important for the future of our planet, and I also fell in love with research and the creativity of it.”
The Bohart Museum is located in Room 1124 of the Academic Surge Building on Crocker Lane. It is the home of nearly eight million insect specimens, plus a live “petting zoo” that includes stick insects, Madagascar hissing cockroaches, tarantulas and praying mantids; and a year-around gift shop.
Richard “Doc” Bohart (1913-2007), former professor and chair of the UC Davis Department of Entomology (now the Department of Entomology and Nematology), founded the insect museum in 1946.
The Bohart Museum is open to the general public Mondays through Thursdays, from 9 a.m. to noon and from 1 to 5 p.m., plus occasional, weekend open houses​. Admission is free. The next weekend open house is from 1 to 4 p.m., Sunday, Nov. 18 and centers around urban entomology..

The 5x6-foot photographic image dwarfs its real-life counterpart, Parnopes grandior, commonly known as the “ruby-tailed wasp,” which measures 1.2 centimeters or about 0.5 inches in length.
Visiting scientists, schoolchildren and the general public who enter the door to Room 1124, Academic Surge Building on Crocker Lane, are marveling at Biss's intricate work, which encompasses more than 8,000 separate images, said Lynn Kimsey, director of the Bohart Museum and professor of entomology at UC Davis.
The ruby-tailed wasp image may rival Dorothy's ruby slippers in the Wizard of Oz. Chrysidid wasps are renowned for their highly sculptured, brilliant metallic colors.
“We chose it partly to honor the work that the museum founder, Richard ‘Doc' Bohart did,” said Kimsey, who was one of his last graduate students. ”It belongs to the group that he researched. He spent much of his career studying chrysidid wasps or parasitoid wasps.”
The “cuckoo” name refers to the fact that the female lays her eggs in the nests of unsuspecting hosts, including the sand wasp, one of its major hosts. Its larvae consume the host eggs, larvae and the stored food.
“It's a European species, found throughout Europe but not here in the United States,” Kimsey related. The wasp, most diverse in arid regions, prefers dry and sandy soils in subtropical and Mediterranean climates.
Members of the Bohart Museum Society funded the wasp image project, part of the museum's major redesign, which includes new signage, graphics and paint in the hallway.
Levon Biss, based in London, works across many genres, including news, sports, portraiture and insects. He developed his interest in insects after his son, Sebastian, found a ground beetle in their backyard. He photographed it and other insects, showed them to the Oxford Museum of Natural History, and gained access to the museum's historical collection of insects, including some collected by Charles Darwin.
Biss now creates micro-scale images for what he calls his Microsculpture series. Over the course of two years, he photographed 37 insects from the Oxford collection. To create the final insect portraits, he composites thousands of images using multiple lighting setups. Biss photographed most of them in about 30 sections, “each section lit differently with strobe lights to accentuate the microsculpture of that particular area of the body.”
In October 2017, Biss drew rave reviews for his TED talk, “Mind-Blowing Magnified Portraits of Insects.”
The British photographer launched a world gallery tour of his images two years ago; the show is now at the Houston (Texas) Museum of Natural Science, July 13, 2018 through Jan. 13, 2019.
Richard “Doc” Bohart (1913-2007), former professor and chair of the UC Davis Department of Entomology (now the Department of Entomology and Nematology), founded the Bohart Museum of Entomology in 1946. He was an authority on the family Chrysididae, which includes more than 3000 described species. During his 32-year academic career, he identified more than one million insect specimens, many of which are housed in the museum that bears his name. Today the museum, dedicated to teaching, research and public service, houses nearly eight million specimens, collected throughout the world. It also includes a live “petting zoo” of stick insects, Madagascar hissing cockroaches, tarantulas and praying mantids, as well as a year-around gift shop.
The museum is open to the general public Mondays through Thursdays, from 9 a.m. to noon and from 1 to 5 p.m., plus occasional, weekend open houses​. The next weekend open house is from 1 to 4 p.m., Sunday, Nov. 18 and centers around urban entomology.

The Hellman Family Foundation contributes funds to support and encourage the research of promising assistant professors who exhibit potential for great distinction in their research. The fellowship is designed to support research and creative activities that will promote career advancement.
Vannette's project, “Characterizing the Structure and Function of Pollinator Microbiomes,” will investigate the communities of bacteria and fungi in flowers and pollinators including bees and hummingbirds. “Our work to date suggests that microbes in flowers are common and influence pollinator behavior,” says Vannette. The current funding will allow her to link microbial communities in flowers with their influence on pollinators by examining microbial modification of nectar and pollen chemistry, and examine how microbial effects vary among plant and pollinator species, and with environmental variation.
The 11 assistant professors will receive a total of $244,000 in grants for research in a wide range of disciplines. Since 2008, UC Davis has received nearly $3 million in Hellman grants, awarded to 136 early-career faculty members. The Hellman Fund provides grant monies to early career faculty on all 10 UC campuses, as well as to four private institutions.
Vannette is one of two recipients from the College of Agricultural and Environmental Sciences. The other is Frances Moore, an assistant professor, Environmental Science and Policy. Her project title: "Quantifying the Costs of Ecosystem Damages from Climate Change for Improved Climate Policy Analysis.”
The community ecologist joined the UC Davis Department of Entomology and Nematology in 2015 after serving as a postdoctoral fellow at Stanford University's biology department, where she was a Gordon and Betty Moore Foundation Postdoctoral Fellow from 2011 to 2015 and examined the role of nectar chemistry in community assembly of yeasts and plant-pollinator interactions.
Vannette received her bachelor of science degree, summa cum laude, in 2006 from Calvin College, Grand Rapids, Mich., and her doctorate from the University of Michigan's Department of Ecology and Evolutionary Biology, Ann Arbor, in 2011. Her thesis: “Whose Phenotype Is It Anyway? The Complex Role of Species Interactions and Resource Availability in Determining the Expression of Plant Defense Phenotype and Community Consequences.”
