A team of scientists, including Christian Nansen, agricultural entomologist at the University of California, Davis, answered those questions in their research, “How Do ‘Mute' Cicadas Produce their Calling Songs?” in the Feb. 25th edition of PLOS ONE, an open access peer-reviewed scientific journal published by the Public Library of Science.
Cicadas in the genus Karenia lack the specialized sound-producing structures that characterize most cicadas, according to Nansen and colleagues Changquing Luo and Cong Wei, both of Northwest A&F University, China.
Although they don't possess the tymbal mechanism, the word “mute,” is misleading, says Nansen, assistant professor in the UC Davis Department of Entomology and Nematology. “They do indeed produce sounds.”
The researchers discovered a new sound-production mechanism in Karenia caelatata, which produces impact sounds by banging the forewing costa against the operculum. It's somewhat like beating a drum while other cicada species with tymbal mechanisms play an orchestra of diverse and loud sounds.
In their publication, the researchers described the temporal, frequency and amplitude of the sound produced.
“Morphological studies and reflectance-based analyses reveal that the structures involved in sound production of K. caelatata(i.e., forewing, operculum, cruciform elevation, and wing-holding groove on scutellum) are all morphologically modified,” they wrote. “Acoustic playback experiments and behavioral observations suggest that the impact sounds of K. caelatataare used in intraspecific communication and function as calling songs.”
“The new sound-production mechanism expands our knowledge on the diversity of acoustic signaling behavior in cicadas and further underscores the need for more bioacoustic studies on cicadas which lack tymbal mechanism,” they concluded in their abstract.
Cicadas, also known as “tree crickets” (from Latin cicada), are among the most widely recognized of insects due to their large size, usually 2 to 5 centimeters or more, and loud sounds, sometime as high as 120 decibels. Theirs is among the loudest of all insect-produced sounds. Cicadas live in warm climates, from temperate to tropical. Immature cicadas spend most of their lives sucking juice from tree roots. The adults suck plant juices from stems.
The best-known North American genus, Magicicada, has a long life cycle of 13 or 17 years and emerges in great numbers.
Cicadas damage cultivated crops, shrubs, and trees, mainly from females scarring tree branches where they lay their eggs. In many cultures, cicadas are a delicacy on the menu.

“The agricultural sector in California is so exciting, because of its diversity and economic importance,” said Nansen, whose agricultural entomology expertise encompasses seven countries including his native Denmark. “Secondly, there is a strong spirit of innovation in this region, and I hope to contribute to the development of highly advanced crop monitoring systems and decision support tools, so that farming practices can become less reliant on pesticides.”
“I also believe that the strong academic programs at UC Davis with ecology and evolution are of incredible value, and that we can integrate the basic theory from these disciplines into the fundamental of crop management to obtain more sustainable farming systems,” Nansen said. “As an example of a line of research I am interested in – application of fertilizers obviously affect crop growth, but they also affect the attractiveness of crops to many insect pests, and they influence the ability of plants to resist attacks by several important insect pests.”
“So, how can we optimize use of crop fertilizers to stimulate yields but also minimize risks of pest infestations? The answer to such a question is underpinned by in-depth understanding about host selection ecology and about fitness and evolutionary processes involved in host adaptation. In other words, it is critically important to demonstrate how we can use studies of agricultural systems to learn about the ecology of species and their food webs and evolutionary processes.”
At UC Davis, Nansen is focusing on four major themes: host plant stress detection, host selection by arthropods, pesticide performance, and use of reflectance-based imaging in a wide range of research applications.
As part of his undergraduate studies, Nansen took time off to travel to Brazil to write a book about sustainable agriculture in rainforest areas. “In this process, I learned about the potential of honey bees as both pollinators of crops but also as ‘promoters' more broadly of sustainable agricultural development,” Nansen said.
Nansen wrote his master's thesis on honey bees: “The Apis mellifera Forging Response to the Pollen Availability in Cistus salvifolius.” The plant isalso known as a sage-leaved rock rose or Gallipoli rose. He conducted field work in Portugal involving pollen identification, observations on daily flight and foraging activity, and modeling of pollen availability.
For his doctorate, his interest turned to the larger grain borer, a serious pest of stored maize and dried cassava roots. He wrote his dissertation on “The Spatial Distribution and Potential Hosts of the Larger Grain Borer, Prostephanus truncatus (Horn) (Coleoptera: Bostrichidae), in a forest in Benin, West Africa.” His research involved stored product insect ecology, field trapping with pheromone traps, experimental work on pheromone production, vegetation analysis, satellite image interpretation, laboratory infestation of potential breeding substrates, and histological studies.
“Agricultural entomology has given me so many opportunities to travel and work internationally, and that has been extremely rewarding,” he said. “I am passionate about food production and how to produce food ‘smartly' – so that it is profitable and also environmentally sustainable. And insects are critically important in manipulated food webs, such as, a crop field, forest, orchard, or horticultural greenhouse. I enjoy studying their ecological roles in these systems and how we can use that information to develop smarter ways to produce food.”
Nansen recalled that his childhood exposures to international scientists played a major role in his choice of a career. His father, a professor in veterinary parasitology, entertained many colleagues in the family home. “And my mother cooked the food! This is probably the main reasons why I enjoy both cooking and why my career has been so international.”
“Even though Denmark is a very small country (5 million people),” Nansen said, “it has been at the forefront of agricultural research and production for many decades. And growing up, my father took me on field trips and exposed me to farming systems.” In fact, young Christian earned his weekly allowance in the chicken business: he sold eggs to neighbors.
Nansen said he is delighted to see a “steadily growing appreciation for the origin and quality of the food we eat. Today, in the 21st century, the technologies deployed in modern agriculture are so advanced and similar to the cutting-edge technologies in other fields, he said. “Those technologies require skill sets beyond what most people may be aware of. Use of drones, remote sensing, GIS models, mathematical models of weather, crop physiology and soil dynamics, models to optimize input requirements and minimize economic risks, phone apps to optimize applications of agro-chemicals – these are all skill sets and approaches we are using as part of studying food production systems and developing innovative and reliable tools to be used within the agricultural sector.”
Nansen previously held faculty positions at Texas A&M, Texas Tech, and most recently at the University of Western Australia. As a university employee, the most common way to “create impact” is by influencing the minds and interests of students, but also of particular stakeholders,” he said.
“While working in Texas, we developed a very effective sampling method for an important insect pest in potato fields, and a 4th generation potato grower (Bruce Barrett) actually changed his management strategy because of our sampling method: he purchased the equipment needed and hired people specifically to conduct insect sampling, as he saw how use of this method could save him thousands of dollars on insecticide sprays--because he would now have a much better idea about when and where to spray. Recently, in Australia we demonstrated to farmers that sub-optimal maintenance of their stored seed grain led to loss of crop vigor and therefore a loss in crop yields. That is, if the seed grain is poorly managed, then stored grain infestations will likely occur, and these beetles will damage the kernels so they don't germinate. We provided simple guidelines for how the grain storage practices could be improved, so quite a few farmers are now following our guidelines to optimize the vigor of their seed grain.”
“Sometimes, we can go further and actually develop tools or gadgets which end-users may find useful. As an example, we have developed a freely available phone app to optimize pesticide spray applications based on weather and spray settings (http://agspsrap31.agric.wa.gov.au/snapcard/). The main goal with this phone app is to guide farmers so that they obtain the best possible spray coverage--to reduce risk of pests developing resistance--and to encourage them NOT to spray pesticides under unfavorable conditions.”

Burton, who served the UC Davis Department of Entomology for 28 years as an Extension entomologist, died Jan. 22, 2015 at age 90 in Davis.
Burton was born June 3, 1924 in Omaha, Neb., the only child of John and Vesta Burton. In July 1943, he was inducted into the U.S. Army and sent to Camp Adair, Ore., to a new wartime infantry division – the 70th Infantry “Trailblazer” Division. He fought in the Battle of the Bulge and was discharged in April, 1946 with the rank of technical sergeant.
He wed Charlotte McKnight and they were married for more than 66 years. He earned a bachelor's degree in entomology from UC Berkeley and a master's from Louisiana State University. He spent his 38-year career with the Agricultural Extension branch of the University of California. He served 10 years as an entomology farm adviser in Bakersfield, followed by 28 years at UC Davis as an entomologist specialist.
Burton was a lifetime member of Kiwanis International and an active member of the Davis Kiwanis Club. An avid golfer, he allso loved playing bridge, family board games and reading, but mostly cherished spending time with his family.
He is preceded in death by his parents, Vesta and John Burton, and his wife Charlotte Burton. He is survived by his daughters Maryn Mason (Bill) and Anice Isaacs (Bob); and granddaughters Kimberly Mason, Audra Anderson (Kory), Rebecca Mason, Ashley Nolan (Bowie).
Burton was known for his sense of humor and ever-present smile. At the celebration of life, plans call for a “Putt One for Vern” contest. In lieu of flowers, remembrances can be made to either The Bohart Museum of Entomology, Department of Entomology and Nematology, 1 Shields Ave., Davis, CA 95616; The Kiwanis Family House, 2875 50th St., Sacramento, Calif. 95817; or The URC Foundation, 1515 Shasta Drive, Davis, CA 95616. Those who wish to sign a guestbook online may do so at www.wiscombefuneral.com.
In 2008, when he was 85, he was interviewed for a Department of Entomology feature story, published on Dec. 18, 2009. Vern Burton said he didn't set out to become an entomologist. Home from the World War II battlefields, he enrolled in Compton Community College and then the University of California, Berkeley.
A family friend promised him a job in his termite control business once he finished his studies. His college associates, however, couldn't envision “Vern and termites” in the same sentence. Neither could he.
“There were better things to do in life than crawling under a house looking for termites,” quipped Burton, known for his wry sense of humor.
During his career, Burton worked with crops such as alfalfa, beans, cotton, potatoes, small grains and sugar beets and helped resolve pest problems through integrated pest management (IPM) strategies and close associations with university researchers.
Burton enjoyed working with researchers like noted alfalfa seed expert Oscar Bacon, now a retired professor and former chair of the UC Davis Department of Entomology. “I'd help identity problems in the field and take them back to the researchers.”
“I always enjoyed helping people in ag and urban settings with their insect problems,” Burton said, “or their perceived problems.”
When Burton retired in December 1988, then Cong. Vic Fazio lauded him for his outstanding contributions to California agriculture, particularly in the field of IPM. In remarks entered into the congressional record on Jan 4, 1989, Fazio said that Burton “contributed greatly to California agriculture and to the University of California's mission for excellence in agricultural research, education and public service.”
“Mr. Burton's outstanding contributions include the development of innovative methods and strategies for nematode control in cotton, which have improved production while reducing pesticide use. He also aided in the development and establishment of treatment thresholds for green peach aphid on sugar beets and established and supervised the cotton pest management program in the San Joaquin Valley in the 1970s. That work resulted in the appropriation of permanent federal funds for an integrated pest management program.”
Other successes included “more effective and efficient control of lygus bugs and spider mites on dry beans, development of a successful pest management program on Burbank potatoes, and investigations on an aphid believed to be a serious insect pest on small grains. Mr. Burton helped prove that the aphid actually had no significant impact on grain yields and thereby insecticide use was markedly reduced.”
Fazio noted that over the years, Burton “has provided support and guidance to county programs conducted by Farm Advisors through field test pilot activities, recommendations, and suggestions for problem solutions, and printed information and participation in educational programs. He has also helped disseminate education and informative entomological information to a diverse clientele in agricultural and urban areas throughout the state.”
In the news story, IPM specialist and professor Frank Zalom was quoted: "“Vern was dedicated to California growers, and worked tirelessly to provide new and useful information to them. He understood the research-extension continuum better than most people ever could, having served the university as an extension entomologist in the county and also here on campus.”
Also active in entomological organizations, Burton served as president and secretary-treasurer of the Northern California Entomology Club and as secretary-treasurer of the Pacific Branch of the Entomological Society of America.
Although born in Nebraska, Vern spent his childhood in several states: Nebraska, Minnesota and Illinois before his father, in the tire business, moved his family to Los Angeles in 1939.
Young Vern joined the Army fresh out of high school and completed basic training in the Willamette Valley, Oregon, where he would meet his future wife, Charlotte.
He said his three years in the Army proved to be “a great educational experience and quite an adventure for someone just out of high school.” He landed in Marseille, France on Dec. 15, “the day the Germans launched the Battle of the Bulge. “I went overseas as a squad leader and came back as a platoon sergeant,” he recalled.
Burton attended Compton in 1946-1948, completing lower division requirements before enrolling at UC Berkeley. He interrupted his UC Berkeley studies in April 1951 to accept a Kern County Farm Advisor position, which he held until September 1960. He completed his 1960-1988 career an Extension entomologist based at UC Davis.
Burton and his wife, a retired 20-year accountant with the UC Davis Viticulture and Enology Department, moved to the University Retirement Community, Davis, in 2004.
In his early retirement years, he served as a lieutenant governor in 1992-93 of Division 7, Kiwanis International; worked four years in the UC Davis Medical Center gift shop and helped with the Kiwanis Family House at the Med Center. He traveled with his family, played golf and fished.
A favorite activity since childhood was “to get up early and go fishing in the morning and fry it for breakfast the same day.”
Extension Apiculturist Eric Mussen, a member of the UC Davis Department of Entomology faculty since 1976 and now emeritus, recalled Vern as a “dedicated scientist with a terrific sense of humor.” They shared office space with two other scientists on the third floor of Briggs Hall.
Vern claimed that bees would always single him out for special attention, Mussen said.
Said Burton: “Whenever I'd watch a honey bee demonstration in alfalfa and clover fields (which bees pollinate), honey bees would find me and deposit their stinger. I'd stay out of the fields if they just moved in the honey bees.”
“There's a place for honey bees in this world and I acknowledge that,” he said, tongue-in-cheek.

The two emeriti professors from the UC Davis Department of Entomology and Nematology were among five honored at the event. Also honored were Dickson recipients/emeriti professor Daniel Anderson of the Department of Land, Air and Water Resources; Martha Macri of the Department of Linguistics; and Peter Schiffman, Department of Geology. (See web page.)
UC Davis Chancellor Linda P. B. Katehi, Provost Executive Vice Chancellor Ralph Hexter, and emcee Bill Rains, past president of the UC Davis Emeriti Association, praised them for their work.
Robbin Thorp
Thorp was singled out for the distinguished emeritus award for his outstanding scholarly work and service accomplished since his retirement in 1994. "Dr. Robbin Thorp should be the first scientist to be cloned," said emcee Rains, quoting James Cane of the USDA-ARS Pollinating Insect Research Unit, Utah State University, Logan.
Thorp, who joined the UC Davis entomology faculty in 1964 and achieved emeritus status in 1994, is a state, national and global authority on pollination ecology, ecology and systematics of honey bees, bumble bees, vernal pool bees, conservation of bees, contribution of native bees to crop pollination, and bees of urban gardens and agricultural landscapes.
Since his retirement, he has compiled an exemplary record for his research, teaching, publications, presentations, and advisement services, sharing his expertise with local, statewide, national and international audiences. In his retirement, he has published 68 papers and is the first author on 15 publications. He received several prestigious awards: the 2013 outstanding team award, with several colleagues, from the Pacific Branch of the Entomological Society of America, and the 2010-2011 Edward A. Dickson Emeriti Professorship, UC Davis. Thorp is the North American regional co-chair for the International Union for Conservation of Nature (IUCN) Bumblebee Specialist group. He is a member of 10 professional societies, including the International Society of Hymenopterists.
Thorp maintains his office and research headquarters in the Harry H. Laidlaw Jr. Honey Bee Research Facility on the UC Davis campus. Among his latest publications: he co-authored two books published in 2014: Bumble Bees of North America: An Identification Guide (Princeton University Press) and California Bees and Blooms: A Guide for Gardeners and Naturalists (Heyday). Of the 20,000 bee species identified worldwide, some 4000 are found in the United States, and 1600 in California.
Thorp spends much of his time in the Bohart Museum of Entomology, which houses collections critical to his bee identification work. He identifies species and regularly volunteers at the open houses and other event.
Thorp is an integral part of The Bee Course, an annual 10-day workshop sponsored by the American Museum of Natural History and held at the Southwestern Field Station near Portal, Ariz. He has taught there since 2002 (the instructors are all volunteers), and even though he is 81 years young, he plans to continue teaching there. (See more on the departmental web page.)
Hugh Dingle
Hugh Dingle. an international authority on animal migration, received a Dickson award to help fund his research on monarch butterflies, “Monarchs in the Pacific: Is Contemporary Evolution Occurring on Isolated Islands?” Monarch butterflies established just 200 years ago in remote Pacific islands are undergoing contemporary evolution through differences in their wing span and other changes, he believes.
Dingle, author of two editions of “Migration: The Biology of Life on the Move,” said his previous studies reveal that migrant and resident monarchs exhibit different wing shapes. He will be working with community ecologist Louie Yang and molecular geneticist Joanna Chiu, assistant professors in the UC Davis Department of Entomology and Nematology, to examine the ecology and physiology of monarch butterflies (Danaus plexippus) in three islands where contemporary evolution might be expected. The islands are Oahu (Hawaii), Guam (Marianas) and Weno (Chuuk or Truk).
“This is the necessary first step in a long-term analysis of the evolutionary ecology and physiology of monarch butterflies on remote Pacific islands,” said Dingle, a fellow of the American Association for the Advancement of Science and the Animal Behavior Society.
Dingle said the monarch, widely distributed “for eons” in the New World, is fairly new to the Pacific islands and to Australia. “In addition to North America, the monarch occurs as a resident throughout the Caribbean and Central and northern South America—and probably as a migrant farther south. One of the more intriguing aspects of its distribution is that beginning in the early part of the 19th century, it spread throughout the Pacific all the way to Australia, where there are now well-established migratory and non-migratory populations.”
Dingle speculates that the monarchs arrived in the Pacific islands with their host plant, milkweed, which was valued at the time for its medicinal properties. Some of the islands are extremely isolated, he said.
An analysis of a monarch population in Hawaii shows that resident monarchs have shorter, broader wings than the long-distance migrants. The Hawaii butterfly wings were shorter than the eastern U.S. long-distance migrants, but “not so short-winged as the residents in the Caribbean or Costa Rica, which have been present in those locations for eons, rather than the 200 years for Hawaii.”
“If there are indeed wing shape changes associated with evolution in isolation, are there other changes that may have occurred under selection and local adaptation for residency?” Dingle wonders. “Are there other changes that may have occurred under selection and local adaptation for residency? Examples of such traits might be changes in flight muscle physiology, changes in photoperiodic diapause response, changes in the characteristics of orientation ability and its relation to antennal circadian rhythms, or changes in the reproductive capacity or tactics (re-colonization of ‘empty' habitats is no longer part of the life cycle).
Dingle published the second edition of “Migration: The Biology of Life on the Move” (Oxford University Press) in November 2014. It is the sequel to the widely acclaimed first edition, published in 1996. National Geographic featured Dingle in its cover story on “Great Migrations” in November 2010. LiveScience interviewed him for its November 2010 piece on “Why Do Animals Migrate?” (See more on the departmental web page.)
Emeriti Luncheon
Preceding the ceremony, Chancellor Katehi presented a progress report on UC Davis, which is ranked No. 9 in the nation's top 10 public universities in rankings released last fall by by U.S. News & World Report. This is the fifth consecutive year that UC Davis has been ranked in the top 10 U.S. public universities.
The UC Davis community includes more than 34,000 students, some 4,100 faculty and other academia, and 17,400 staff. The incoming fall class drew nearly 80,000 applicants, she said.
The UC Davis annual research budget totals more than $750 million. Among the other statistics: UC Davis ranks No. 1 in the world for teaching and research in the area of agriculture and forestry, according to QS World University Rankings.
Katehi said that UC Davis is planning now for the next 30 years, not the next five. "What kind of university will make us proud?" she asked. "What we do today will define us in 30 years."
"Where are we going to be in 30 years?" she asked. "We need to draw a path to get there. We need to know where we're going to be so we can get there."
She thanked the UC Davis Retiree Association for its continuing support. The association was established in 1989 to provide retired academics of UC Davis/UC Davis Health System or other UC campuses living in the Davis/Sacramento area with opportunities for continuing interest in and support for the excellence of UC Davis, according to Sue Barnes, director of the Retiree Center.

Niño, who joined the UC Davis Department of Entomology and Nematology on Sept. 1 from Pennsylvania State University—2600 miles away--is as busy as the proverbial worker bee during a colony's spring buildup as she settles into her new position involving research, education and outreach.
“California is a good place to bee,” she said. “I just wish I could have brought some of that Pennsylvania rain with me to help out California's drought.” Now she is looking forward to the almond pollination season, which brings some 1.5 million colonies from all over the country to California's almond orchards.
Niño operates her field lab at Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road and at her campus lab in Briggs Hall, on the central campus. Her aims: to conduct practical, problem-solving research projects; to support the state's beekeepers through research, extension and outreach; and to address beekeeper and industry concerns.
Niño, who studies honey bee biology, health, reproduction, pollination biology, insect ecology, evolution, genomics and chemical ecology, and genomics, replaces Eric Mussen, who retired in June 30 after 38 years of service. “Elina is a very accomplished scientist,” said Mussen. “Her research involves the reproductive processes involved in queen bee mating, including the impacts of oviduct manipulation, insemination volume and insemination substances. The induced changes include measurable behavioral, physiological and molecular alterations that occur, including differences in behavioral interactions between queens and worker bees.”
Niño has already met with many of the state's beekeepers, attended meetings of the California State Beekeepers' Association, the California Bee Breeders' Association, and the Almond Board of California, and charmed youngsters from the California School of the Blind, Fremont who asked many questions about honey bees.
“I love meeting people,” she said. She delights in answering questions, including those from inquisitive school children.
One of the most common questions: “Do you get stung?” Answer: “Yes, many times.”
Some don't know that all worker bees are females, that they do all the work. They are fascinated with the queen bee, which can lay as many as 2000 eggs a day during peak season. Once a youngster, thinking about the queen bee, asked: “What happened to the king?”
Bees are in a global decline due to pesticides, parasites, pests, malnutrition and stress. Niño says most people have heard of colony collapse disorder, and many know that the average beekeeper loses approximately 30 percent of the colonies each winter due to the combined effect of various pests, pathogens, environmental toxins, and poor nutrition.
“My research and extension goals are to provide stakeholders with practical tools that better equip them to confront these challenges. My primary research focus is to characterize biological factors that regulate honey bee queen reproduction. By better understanding these factors, we can improve the honey bee breeding protocols necessary for creating and maintaining resilient honey bee stock.”
Elina Niño wasn't always so devoted to bees. Born and reared in Bosnia in Eastern Europe, Elina moved to the United States with plans to become a veterinarian. She obtained her bachelor's degree in animal science at Cornell University, Ithaca, N.Y., but while there, enrolled in an entomology class on the recommendation of her advisor. “I was hooked,” she recalled.
Following her graduation from Cornell in 2003, she received her master's degree in entomology from North Carolina State University and her doctorate in entomology from Pennsylvania State University. While at Penn State, she sought to add to her applied-research expertise and gain experience in basic research. She joined the honey bee lab of Christina Grozinger, who studies the genomics of chemical communication and collaborates with researcher David Tarpy on understanding queen bee post-mating changes.
After attending her first lab meeting, “I was hooked again!” Niño recalled.
She and her fellow researchers confirmed that carbon dioxide causes queens to stop attempting mating flights and helps them start producing eggs. They also found that instrumental insemination triggers changes in Dufour's gland pheromone. Understanding the regulation of reproductive processes can lead to better management practices for improved colony productivity and health, Niño said.
Niño is now settled in Davis with her husband, Bernardo Niño, a former senior research technologist in the Grozinger lab and now a staff research associate at the Laidlaw facility; their toddler son, Sebastian; and their dog, a Doberman named Zoe.
Bernardo, who managed some 40 to 50 colonies at Penn State, received his bachelor's degree in biology from St. Edward's University, Austin, Texas; and his master's degree in entomology from North Carolina State University, Raleigh, NC.
Elina is building up her research team, which includes Bernardo; and staff research associate Billy Synk and doctoral candidate W. Cameron Jasper of the Brian Johnson lab.
“We view ourselves as the liaison between the beekeepers and other relevant growers and the scientific community,” Elina said. “We are continuing research on queen mating and reproduction, especially considering the importance of Northern California beekeepers for the queen rearing and bee breeding enterprises.”
They will expand their work to include studies “crucial for supporting honey bee health.” Current collaborate work includes examining the effects of Israeli Acute Paralysis Virus, Deformed Wing Virus and Nosema gene expression regulation and longevity in workers. Understanding the molecular mechanisms that underlie individual responses to specific honey bee pathogens, Elina said, “can lead to the implementation of appropriate beekeeping practices.”
“In the near future, we plan to contribute to the general understanding of synergistic effects of pesticides on honey bee health and collaborate on research evaluating alternative Varroa mite control.”
Her lab not only aims to conduct applied research that leads to practical solutions, but to alert the state's beekeepers about new research, and develop web-based educational tools. She write the bimonthly newsletter, “from the UC apiaries,” appearing on the UC Davis Department of Entomology and Nematology's website. In addition, she will be serving on various advisory boards to allow “us to guide decision making and legislation based on the most up to date scientific information.”
How would she describe herself? “Like a rock. I don't get easily disturbed. There's not a lot that fazes me. I find a way to figure out a problem and find a solution.”
Now she and her “Bee” team--that is, Bernardo and Billy--are gearing up for their inaugural queen bee rearing short-course March 28-29 at the Harry H. Laidlaw Jr. Honey Bee Research Facility. It is open to beekeepers with basic bee experience who want to learn more about rearing queens.
Another pending activity: she'll be judging the California 4-H Honey Bee Essay Contest, “Planting for Bees from Backyards and Up” (http://preservationofhoneybees.org/essays) next February. The contest closes Feb. 20.
Meanwhile, Niño has set up her lab's website at http://elninobeelab.ucdavis.edu/; a Facebook page at https://www.facebook.com/elninolab and has obtained an easy-to-remember email, elnino@ucdavis.edu.
“California is a good place to bee,” she reiterated.
