UC Davis alumnus Hannah Burrack, a professor of entomology and extension specialist at North Carolina State University, Raleigh, has been named chair of the Department of Entomology at Michigan State University, East Lansing, effective Jan. 1, 2022. Burrack will replace F. William Ravlin, the chair since 2014. 

 “Hannah's background in extension, combined with her research experience and administrative skill set makes her a great fit for our college, its students and for our stakeholders in Michigan,” said interim dean designate Kelly Millenbah, of the College of Agriculture and Natural Resources (CANR) in a news release. “Hannah is also committed to undergraduate and graduate student development and has supported various mentoring initiatives.”

Said Burrack: "I have followed the innovative research, exceptional students, and impactful extension undertaken by the MSU Entomology Department from the very start of my career, and I am thrilled to be joining this team in January. I am passionate about science that connects with stakeholders—be that students, growers, industry partners, or the broader citizens of the state. Entomology as a discipline naturally fosters these connections, and I am so excited to work together with the faculty, students, and staff at MSU to do great things!”

Burrack received her doctorate from UC Davis Department of Entomology and Nematology in 2007, studying with Frank Zalom, UC Davis distinguished professor and a former president of the 7,000-member Entomological Society of America (ESA). She also received her master's degree from UC Davis.

"Hannah is going to make a great chair," Zalom said. "She has great communication skills, vision and energy." 

When she joined NC State in 2007 as assistant professor and Extension specialist for small fruits and tobacco pest management, Zalom said: "The NC State faculty made a very wise choice in hiring her. Hannah has the complete package when it comes to IPM research and extension, and I have every confidence that she will be a leader of her generation of IPM specialists."

At NC State, Burrack directs Education & Outreach for the NC Plant Sciences Initiative, an interdisciplinary initiative with the goal of conducting transformational plant sciences research, education, and outreach, according to the news release. Her current research focuses broadly on the ecology of insect pests in tobacco and small fruit crops; she utilizes the information to enhance pest management. Her extension appointment supports tobacco production and small fruit crop diversification, as she works with local and regional growers.

Burrack, known for her “boundless energy and fresh ideas,” served as the principal investigator and manager of several USDA National Institute of Food and Agriculture grants and panels related to research on spotted wing drosophila management, crop protection, pest management and methyl bromide transitions. In 2018, she received the University Faculty Scholar Award and the Extension Service Award from NC State University. 

The UC Davis alumnus  "has been part of extension engagement and outreach with stakeholders; taught courses in entomology, horticulture and crop sciences departments; supported undergraduate research projects; and mentored students and visiting scholars," according to the news release. "She has also been a part of various NC State University committees related to teaching and tenure, extension, research and technology, as well as faculty search committees."

Burrack was named the 2011 recipient of the “Future Leader” award from the Southern Region Integrated Pest Management  (IPM) Center. She received the Friends of IPM award at the annual meeting of the Southeastern Branch of ESA, held in San Juan, Puerto Rico. The Friends of IPM Future Leader award recognizes IPM leaders early in their career for their excellent work.

Registration for the comprehensive, asynchronous course, "Honey Bees and Beekeeping for Veterinarians," is now underway at http://www.wifss.ucdavis.edu/beevets/. The course is intended for veterinarians, veterinary technicians, apiculture educators, apiary inspectors and beekeepers in California and Oregon.  course, "Honey Bees and Beekeeping for Veterinarians," is now underway at http://www.wifss.ucdavis.edu/beevets/. The course is intended for veterinarians, veterinary technicians, apiculture educators, apiary inspectors and beekeepers in California and Oregon. Participants are encouraged to register today; the course will be available only until June 30, 2020. 

The U.S. Food and Drug Administration's Veterinary Feed Directive (VFD) addresses antibiotic resistance and antimicrobial use in the feed or water of food-producing animals. The VFD implementation aims to ensure the judicious use of antimicrobials, and to minimize the impact of their use in colonies.

This means that beekeepers now need to establish a veterinarian-client-patient relationship to obtain the antibiotics they need to manage foulbrood and other microbial diseases.

Topics covered in this online course will include prudent use of antibiotics, the Veterinary Feed Directive, bee biology, and beekeeping techniques and tools. "By bringing veterinarians together with apiculturists through education, we can maintain strong, healthy colonies for specialty crop pollination and safe honey production for consumers," a spokesperson said.

The training is being offered by the laboratory of Extension apiculturist Elina Lastro Niño, affiliated with the UC Davis Department of Entomology and Nematology and the UC Agriculture and Natural Resources;  the UC Davis School of Veterinary Medicine, and OSU.

Course authors and developers are the Western Institute for Food and Security (WIFSS), UC Davis; Elina Niño and Bernardo Niño; Jonathan Dear, UC Davis School of Veterinary Medicine, and Ramesh Saglii, OSU's Honey Bee Laboratory.

Upon completion of the course, the participants will be able to:

• Describe the importance of honey bees
• Explain the veterinarian's role in commercial beekeeping
• Recognize distinguished characteristics of honey bees
• Recognize specialized beekeeping equipment, including personal protective equipment (PPE)
• Recognize the components of a hive inspection
• Describe honey bee immunity against pathogens, pests and diseases
• Describe common pests and diseases that may impact honey bees
• Describe how the Veterinary Feed Directive (VFD) governs the use of antimicrobial drugs in apiculture

Honey bees are responsible for pollinating one-third of the American diet. They pollinate such specialty crops as apples, melons, cranberries, pumpkins, squash, broccoli, and almonds. However, annual honey bee colony losses are high due to a variety of environmental and biological causes, including bacterial diseases. Historically, beekeepers have self-prescribed antibiotics to control these diseases. 

Funding for the development of the “Honey Bees and Beekeeping for Veterinarians” course was made possible by the U.S. Department of Agriculture (USDA) Specialty Crop Multi-State Program through an agreement between the California Department of Food and Agriculture and The Regents of the University of California, Davis (agreement number 17-0727-001-SF).

Entomological offerings will be showcased at the 107th annual UC Davis Picnic Day, themed "Discovering Silver Linings," to take place virtually on Saturday, April 17.

Silver linings promise to grace this family-oriented event, billed as informative, educational and entertaining. 

Picnic Day officials have released the schedule of events that includes entomological exhibits and talks from the UC Davis Department of Entomology and Nematology, Bohart Museum of Entomology and the UC Davis Graduate Student Association. 

Here's a quick list: 

Bohart Museum of Entomology

Bohart associate Greg Kareofelas, Bohart Museum associate and naturalist, has created a pre-recorded video on the Gulf Fritillary butterfly, Agraulis vanillae. These orange-reddish butterflies have  silver-spangled underwings, are glorious. Kareofelas will showcase them and show you how to rear them, which is what he did last year during the pandemic. It's on YouTube at https://www.youtube.com/watch?v=OR3WwE7mbrA.   

Entomologist Jeff Smith, the volunteer curator of the Lepidoptera collection at the Bohart, will present a live Zoom event from 1 to 2 p.m. on Saturday on mimicry in Lepidoptera (moths and butterflies). "I will briefly mention camouflage," Smith says, "and spend most of the time on mimicry for defense--mimics of toxic or distasteful species, mimicry using odors or sounds, mimics of snakes or spiders, and mimics of non-food materials such as bird feces."

Zoom Passcode: 160485

"People who want to submit their questions to Jeff or request to see certain species from the collection can email their requests to bmuseum@ucdavis.edu with Picnic Day in the subject," says Tabatha Yang, the Bohart Museum's education and outreach coordinator. "We won't have the time or capacity to access the collection during the event for any requests. Instead, we will pull the items that are requested or relevant to the talk and have those prepared to show. Of course we may not be able to honor everyone's request, but we will do our best."

The Bohart Museum, located in Room 1124 of the Academic Surge Building on Crocker Lane (the museum is closed now due to the pandemic), is directed by Lynn Kimsey, UC Davis professor of entomology. It houses nearly eight million insect specimens, plus a year-around gift shop and a live "petting zoo," comprised of Madagascar hissing cockroaches, stick insects and tarantulas.

“However, the plants that are keeping up with climate change might also experience costs to earlier leaf-out,” said Meineke, lead author of the first-of-its-kind study, Phenological Sensitivity to Temperature Mediates Herbivory. 

One of the costs is that “early” species get eaten more in warmer years. “This seems to be because when they leaf out earlier,” she said, “they also lengthen the amount of time herbivores have in a given year to eat their leaves.” 

Two plant species that showed higher insect damage due to rising temperatures were two native blueberries: Vaccinium angustifolium, a wild lowbush blueberry native to eastern and central Canada and the northeastern United States, and Vaccinium corymbosum, the northern highbush blueberry, a native North American species and a significant commercial food crop. 

The publication is the result of a massive five-year research project involving herbarium specimens collected from the northeastern United States and France from 1900 to 2015.  These two areas have warmed more than the global average, Meineke said, and the plants studied are distributed widely across them.

Meineke, an assistant professor who joined the UC Davis faculty in March 2020, launched her research while a National Science Foundation postdoctoral fellow at the Harvard University Herbaria, where she studied how worldwide urbanization and climate change have affected plant-insect relationships over the past century.

“This was a true collaboration,” Meineke said. “Each of us was interested in different pieces of the research. Davies and Davis brought the phenology hypotheses and expertise, and I brought an interest in/knowledge of herbivory and how it may change as the climate warms.” 

The authors wrote that “both insect and plant development are sensitive to temperature, though the specific cues plants and associated insects use to time life history events may differ and include photoperiod, chilling, ‘forcing' and precipitation. For the vast majority of insect and plant species, the combined and relative contributions of these cues have not been well characterized.” 

The specimens studied were selected first on the basis of the availability of previously published phenological sensitivity metrics: flowering sensitivity and leaf-out sensitivity. “We use the general term ‘phenological sensitivity' to refer to the extent to which a particular life event (e.g., for plants, budbreak, leaf-out, flowering, fruiting) responds to temperature from year to year (e.g. days change in phenology per ‘C' warming),” they explained. 

The next step? “We are now beginning to look into whether and how herbivory might have shifted over time in California native plants,” Meineke said. “Our focal species so far is the valley oak, Quercus lobata, but we hope to eventually expand these observations to more taxa. We're also looking into other mechanisms that might drive herbivory shifts here in the west, where phenology is driven more by moisture than by temperature.” 

A native of Greenville, N.C., Meineke holds a bachelor's degree from the University of North Carolina in environmental science, with a minor in biology, and a doctorate in entomology from North Carolina State University where she completed her dissertation,  "Understanding the Consequences of Urban Warming for Street Trees and Their Insect Pests.” 

The project was supported by a Discovery Grant from the Natural Sciences and Engineering Research Council of Canada. The material is based upon work supported by the National Science Foundation Postdoctoral Research Fellowship in Biology in a grant awarded to Meineke. 

The abstract:

Species interactions drive ecosystem processes and are a major focus of global change research. Among the most consequential interactions expected to shift with climate change are those between insect herbivores and plants, both of which are highly sensitive to temperature. Insect herbivores and their host plants display varying levels of synchrony that could be disrupted or enhanced by climate change, yet empirical data on changes in synchrony are lacking. Using evidence of herbivory on herbarium specimens collected from the northeastern United States and France from 1900 to 2015, we provide evidence that plant species with temperature‐sensitive phenologies experience higher levels of insect damage in warmer years, while less temperature‐sensitive, co‐occurring species do not. While herbivory might be mediated by interactions between warming and phenology through multiple pathways, we suggest that warming might lengthen growing seasons for phenologically sensitive plant species, exposing their leaves to herbivores for longer periods of time in warm years. We propose that elevated herbivory in warm years may represent a previously under appreciated cost to phenological tracking of climate change over longer timescales.
