Do you know who discovered it?
That would be UC Davis distinguished professor James R. Carey of the Department of Entomology and Nematology, who will present a departmental seminar at 4:10 p.m. Wednesday, May 25, on "The Conceptual Sweep of a Mathematical Discovery in Insect Biodemography: From Medfly Populations to the U.S. Congress."
You can attend the seminar in person at 122 Briggs Hall, UC Davis campus, or access it via Zoom. The Zoom link is https://ucdavis.zoom.us/j/99515291076.
"Twenty years ago while attempting to develop a new concept for studying insect aging in the wild, I discovered a previously unknown mathematical identity now referred to in the formal demography literature as the eponym Carey's Equality—the age distribution of a stationary population equals the distribution of lifetimes yet to come," Professor Carey says in his abstract. "In this seminar I will present my attempts at both operationalizing the concept for study of populations of insects and other non-human species, and generalizing it for applications to groups with fixed numbers of members and where renewal involves birth and death processes."
"These general applications include data from a British cemetery, the National Basketball Association, the Baltimore Longitudinal Health Study, the U.S. Congress (both chambers) and the world population," said Carey, a member of the UC Davis Department of Entomology and Nematology faculty since 1980. "After discussing implications and extensions of the identity, I will wrap up with descriptions of five simple but important demographic relations that all entomologists should know."
Highly honored for his research, teaching and public service, Carey served as the principal investigator of a 10-year, $10 million federal grant on “Aging in the Wild,” encompassing 14 scientists at 11 universities.
Biodemography Textbook. In 2020, he and Deborah Roach, professor and chair of the University of Virginia's Department of Biology, co-authored a 480-page textbook, Biodemography: An Introduction to Concepts and Methods, published by Princeton University Press and hailed as the “definitive textbook for the emerging field of biodemography, integrating biology, mathematics and demography.” Carey recently created a free-access, video guidebook with a playlist of 175 separate presentations, subtitled in 300 different languages. He storyboarded the script, turned graphs, schematics, tables and equations into animated slides, and then with teleprompter assistance, narrated and video-recorded the 175 presentations, which span 12 hours of viewing. It appears on UC Berkeley Population Sciences website at https://bit.ly/3FTge7u.
An internationally recognized teacher, Carey won a 2018 global award in the Robert Foster Cherry Award for Great Teaching Program, an academic competition sponsored every two years by Baylor University, Waco, Texas. He received the 2015 Distinguished Achievement in Teaching Award from the Entomological Society of America (ESA) and the 2014 Distinguished Teaching Award from the Pacific Branch of ESA. The UC Davis Academic Senate honored him as the recipient of its 2014 Distinguished Teaching Award, given to internationally recognized professors who excel at teaching.
Carey is a fellow of four organizations: American Association for the Advancement of Science, Entomological Society of America, California Academy of Science and the Gerontological Society of America. He holds a doctorate in entomology (1980) from UC Berkeley, and two degrees from Iowa State University: a bachelor of science degree in animal biology (1973) and a master's degree in entomology (1975).

It's World Bee Day!
How did that come about?
One word: Slovenia.
The Republic of Slovenia, rich in beekeeping history, asked the United Nations to proclaim an annual World Bee Day, and following a three-year international effort, the United Nations agreed to do so in December 2017.
So May 20 is the annual World Bee Day.
"Slovenia LOVES bees and beekeeping and it seems like California does, too!" says Wendy Mather, program manager of the UC Davis-based California Master Beekeeper Program (CAMBP). "There are 72 Apprentice Assistant and 93 Apprentice level candidates vying for their CAMBP certification this year! The '22 season is buzzing."
Mather points out: "World Bee Day is a confirmation that we humans respect and appreciate our dependence on one of our favorite generalist pollinators, the honey bee, for a healthy, diverse diet. Bee health equals human health and we thank all our CAMBP volunteers for their service to humanity in helping to raise awareness of the importance of bee health and science-based beekeeping. Our members are honey bee ambassadors and are committed to environmental stewardship."
Cooperative Extension apiculturist Elina Lastro Niño of the UC Davis Department of Entomology and Nematology, is the founding director of CAMBP. The organization has disseminated science-based beekeeping information through a network of trained volunteers since 2016.
CAMBP's vision is "to train Apprentice, Journey and Master level beekeepers so they can effectively communicate the importance of honey bees and other pollinators within their communities, serve as mentors for other beekeepers, and become the informational conduit between the beekeeping communities throughout the state and UCCE staff," according to its website.
Beekeepers and prospective beekeepers can sign up for classes, which run from February through October. Upcoming classes (many online but some in person)
- Honey Bee Health, May 21
- All About Varroa, June 4
- Queen Rearing Basics, June 11
- Pesticides, Colony Collapse Disorder, Research and Hope, June 18
- Wax Working, Honey and Hive Products, July 9
- Advanced Anatomy and Physiology of the Honey Bee, Aug. 13
- Seasonal Honey Bee Colony Management in Southern California, Sept. 17
- Broodminder: Apiary Technology and Honey Bee Health, Oct. 15
- Exploring Beekeeping in Person at the South Coast Research and Extension Center, Irvine, Oct. 22
That's it for the 2022 classes. In addition, there's an "Introduction to Mead" class offered Nov. 5. Mead or honey wine, is the world's oldest alcoholic beverage.
Let's hear it for the bees!

"Celebrating 50 Years of the Dogface Butterfly:California's State Insect"
Scientists and the public will celebrate the 50th anniversary of the California State Legislature' designation of the dogface butterfly as the state insect.
Folsom Lake College professor and Bohart scientist Fran Keller, and Bohart associate Greg Karofelas, a volunteer docent for the Placer Land Trust's dogface butterfly tours, will on hand to discuss the butterfly. The California dogface butterfly, Zerene eurydice, is found only in California. It thrives in the 40-acre Shutamul Bear River Preserve near Auburn, Placer County. The preserve, part of the Placer Land Trust, is closed to the public except for specially arranged tours.
Keller is the author of 35-page children's book, The Story of the Dogface Butterfly, with photos by Keller and Kareofelas, and illustrations by former UC Davis student Laine Bauer. Kareofelas' images include the life cycle of the dogface butterfly that he reared. Keller holds a doctorate in entomology from UC Davis, where she studied with major professor Lynn Kimsey, director of the Bohart and UC Davis distinguished professor of entomology.
Kareofelas and Keller also teamed to create a dogface butterfly poster of the male and female. Both the book and the poster are available online from the the Bohart Museum of Entomology gift shop.
California legislators adopted the dogface butterfly as the official state insect on July 28, 1972. But as early as 1929, entomologists had already singled it out as their choice for state insect. Their suggestion appears in the California Blue Book, published by the State Legislature in 1929. (Read more on how the butterfly became the state insect under the Ronald Reagan administration.)
The dogface butterfly is so named because the wings of the male appear to be a silhouette of a poodle. It is also known as "the flying pansy."
Bohart Museum. The Bohart Museum is the home of a worldwide collection of eight million insect specimens, plus a gift shop and a live "petting zoo," comprised of Madagascar hissing cockroaches, stick insects and tarantulas.

So says Scott McArt, an assistant professor in the Cornell University's Department of Entomology, who will speak on "Pesticide Risk to Pollinators: What We Know and What We Need to Know Better" at the Wednesday, May 4 virtual seminar hosted by the UC Davis Department of Entomology and Nematology.
The seminar begins at 4:10 p.m. The Zoom link:
https://ucdavis.zoom.us/j/99515291076
McArt, who joined the Cornell faculty in 2017, focuses his research on pollinator health and ecology. His areas of expertise include disease ecology, ecotoxicology, community ecology, chemical ecology, and plant-pollinator interactions. He maintains his lab research site at https://blogs.cornell.edu/mcartlab/.
"Research in our lab focuses on the impact of pesticides, pathogens, and habitat on honey bees and wild bees," he writes on his website. "We are particularly interested in scientific research that can inform management decisions by beekeepers, growers and the public. Current research projects include: 1) Understanding pesticide exposure and risk to bees in multiple land management contexts, 2) Combining empirical data with network modeling to understand pathogen transmission in complex plant-pollinator networks, and 3) Understanding how habitat enhancements (e.g., flowers at solar power sites) impact pollinator populations and the services they provide to agriculture."
McArt's duties at Cornell also include director of the Cornell Chemical Ecology Core Facility, and associate curator of the Cornell University Insect Collection.
He writes a monthly column, Notes from the Lab, in American Bee Journal; each month he summarizes scientific publications for a non-scientific audience. "The goal is to make the emerging pollinator health science more approachable and relevant to beekeepers," he says.
He is also a member of the New York State (NYS) Beekeeper Tech Team, which works directly with NYS beekeepers to improve honey bee health, reduce colony losses, and increase profitability of the state's beekeeping industry: https://pollinator.cals.cornell.edu/nys-beekeeper-tech-team/
In addition, McArt coordinates such beekeeping workshops as "Introduction to Honey Bee Queen Rearing" and "Honey Bee Biology and Disease Management for Veterinarians" and engages with growers regarding pesticide risk to bees and creating pollinator-friendly habitat. His extension materials are onsite.
When asked "What gets you out of bed in the morning?" during a new faculty interview, he responded "Most of the factors contributing to declines in bee health (pesticide exposure, lack of floral resources, disease, inadequate management practices) are preventable. With targeted research efforts and educated stakeholders, regulatory agencies and public, we can make a difference."
McArt holds a bachelor of arts degree in environmental and evolutionary biology (2001) from Dartmouth College, Hanover, N.H., and a master's degree in biological sciences (2006) from the University of Alaska, Anchorage. He received his doctorate in entomology in 2012 from Cornell University. He served as a USDA-NIFA (National Institute of Food and Agriculture) postdoctoral fellow at the University of Massachusetts, Amhurst, in 2014, and then as a research scientist at Cornell from 2014 to 2017, before joining the Cornell faculty.

Folks will do just about anything to remove cockroaches from their homes, but when it comes to UC Davis Picnic Day, you can't remove people from them.
Nor would UC Davis Department of Entomology and Nematology want that. Roach Races are an integral part of Picnic Day.
Hundreds of cheering fans showed up at Briggs Hall for the department's Roach Races, held Saturday, April 23 during the 108th annual UC Davis Picnic Day.
Entomology students organized and directed the races, but the real heroes and heroines were the American roaches, reared by UC Davis entomologists and ready to run.
Spectators applauded them wildly, but gasped when a few of the two-inch insects tried to escape into the crowd.
Cockroaches, which belong to the order Blattodea, are primarily nocturnal and “have a tendency to scatter when disturbed,” according to the UC Statewide Integated Pest Management Program (UC IPM).
That they did during the Roach Races.
“There are five species of cockroaches in California that are commonly regarded as pests: German cockroach, brownbanded cockroach, oriental cockroach, American cockroach, and Turkestan cockroach," according to UC IPM. "Indoor cockroaches are known as significant pests of public health, and outdoor species that find their way inside are considered serious nuisance pests as well as potential public health pests. Most cockroaches harbor within moist, dark crevices when not foraging for food. They crawl quickly and may climb rough surfaces. A few species can fly short distances or glide as adults during warm nights, but most have no wings, reduced wings, or otherwise do not fly."
UC IPM says that "Indoor infestations of cockroaches are also important sources of allergens and have been identified as risk factors for development of asthma in children, especially within multi-unit housing environments. The levels of allergens present have been directly correlated to both cockroach density and the conditions that contribute to heavy infestations, such as housing disrepair and poor sanitary conditions.”
Sometimes youngsters participating in Maggot Art, another insect-activity hosted by the UC Davis Department of Entomology and Nematology during Picnic Day, get so attached to the maggots creating art for them that they ask to take them home.
Not so with the UC Davis Roach Races. Not a single person--not a single one--asked to take one home.
