I posted that on May 21, 2009 when Jay--now UC Davis Distinguished Professor Jay Rosenheim--won the first of many teaching awards spearheaded by his students.
He'll soon be UC Davis distinguished professor emeritus. He's retiring at the end of June after 34 years with the Department of Entomology and Nematology (ENT).
The department won't be the same without him.
Rosenheim specializes in insect ecology, integrated pest management, and biological control, and the use of farmer-generated data to enhance pest and crop management ('Ecoinformatics'). He is internationally known for his research on the ecology of insect parasitoids and predators, insect reproductive behavior, and the application of big data, or ecoinformatics, methods in agricultural entomology.
And he was among the seven retiring or newly retired ENT faculty members honored on June 11 at a department-sponsored event at UC Davis Alumni Center.
Professor Louie Yang said it well at the event.
"I've known him for 24 of those years and having seen just a little bit of how much he has done for students, colleagues, and the university in each of those years, it is deeply humbling to reflect upon his cumulative career-long contribution to science and mentorship."
"I've come to see that there are many ways to be a professor," Yang continued. "Jay's way has long been characterized by creative scholarly achievements, thoughtful and intentional contributions to agriculture, an intuitive feel for his organisms and a natural intuition for the quantitative side of ecology. I've also had a chance to witness and benefit from Jay's commitment to mentorship up close. Jay has provided mentorship to students and faculty alike, and I've benefited from both. His mentorship is characterized by good judgment and empathy; he is quick to forgive mistakes and genuine in celebrating your successes. On our campus, he's provided leadership of a quiet doing kind, often working behind the scenes to make important things happen and to provide a calming and moderating influence in challenging times."
Yang concluded with "I will sorely miss having Jay as a colleague. But I want to end with a heartfelt thanks. Thanks for all you've done for us over the many years, and for passing the baton. We wish you all the best on the road ahead."
A native of Yorktown, N.Y, young Jay developed an interest in biology while exploring the vernal pools behind his Hudson River Valley home. As an undergraduate at UC Davis, he initially majored in physics. "On a lark" he enrolled in Professor Harry Kaya's Entomology 100 course in 1981. The professor inspired him, the class enthralled him, and insects captivated him.
Rosenheim's career has not only led to his being elected a Fellow of the Entomological Society of America (ESA) and a Fellow of the American Association for the Advancement of Science, but recipient of teaching awards from the Associated Students of UC Davis and the UC Davis Academic Senate; the Distinguished Student Mentoring Award from ESA's Pacific Branch and the campuswide Graduate Program Advising and Mentoring Award.
Rosenheim co-founded and co-directs the campuswide Research Scholars Program in Insect Biology (RSPIB) with Professors Joanna Chiu (now chair of the department) and Yang. The program aims to provide "undergraduates with a closely-mentored research experience in biology," according to the website. "Because insects can be used as model systems to explore virtually any area of biology (population biology; behavior and ecology; biodiversity and evolutionary ecology; agroecology; genetics and molecular biology; biochemistry and physiology; cell biology), faculty in the program can provide research opportunities across the full sweep of biology. The program's goal is to provide academically strong and highly motivated undergraduates with a multi-year research experience that cultivates skills that will prepare them for a career in biological research."
Rosenheim is the kind of professor who ignites, inspires and supports you. He recently reflected on his role: "The job of a professor is quite diverse, and quite rewarding in different ways. Teaching in a classroom provides instant gratification, as you see the light of understanding and excitement shining in students' eyes as they explore and grasp new concepts. Research in the laboratory provides instead delayed gratification, where long periods of hard work--sometimes years--may pass before questions are answered and one feels the satisfaction of pushing forward the margins of scientific understanding."
"But, perhaps the most lasting sense of accomplishment comes from mentoring graduate students," Rosenheim related. "Building relationships with graduate students, watching them grow in their skills and confidence and, finally, seeing them establish themselves in their careers, provides the kind of reward that is similar in some ways to the happiness that parents derive from their children. And the relationships never end--they are bonds that last a lifetime. I think the key to effective mentorship is to place the student's welfare at the top of one's priority list. So, drafts of papers should be returned promptly with constructive suggestions, and not allowed to languish in a long queue of manuscripts waiting for reviews--more senior colleagues can wait, if someone needs to wait."
We owe a debt of gratitude to UC Davis Distinguished Professor Jay Rosenheim, exemplary teacher, mentor and researcher, and wish him well in his retirement.

If you're struggling with triple-digit temperatures, think about the honey bees.
They need to collect water for their colony to cool the hive so their brood can develop. And for other purposes.
Just call them "The Water Girls."
Lately the bees have taken a liking to our birdbath. The birds? They're practicing social distancing.
We remember Extension apiculturist Eric Mussen (1946-2022) telling us "Like most other animals, the bodies of honey bees are mostly water. Thus, they need to drink water routinely as we do. Additionally, water (or sometimes nectar) is critical for diluting the gelatinous food secreted from the head glands of nurse bees, so that the queen, developing larvae, drones, and worker bees can swallow the food. They use water to keep the brood nest area at the proper relative humidity, especially when it gets hot and dry outside the hive. Water droplets, placed within the brood nest area, are evaporated by fanning worker bees and that cools (air conditions) the brood nest area to keep the eggs and developing brood at the critical 94 degrees Fahrenheit required for proper development."
Unlike us, honey bees cannot simply turn on a faucet. "They will fly up to nearly five miles to find a suitable watering source," Mussen told us back in 2014. "Suitable to honey bees might not be suitable to us, but if it is moist, it may be visited. Suitable to the neighbors is a separate question. Honey bees can become quite a nuisance if they visit drippy irrigation lines or hose connections, birdbaths, pet water dishes, swimming pools, fountains, or wet laundry and the like. The water foragers become habituated to those sites. If you try to dissuade the bees by drying up the source for a while, it becomes evident that the bees will visit the site every so often so they'll be around quickly after the water is returned."
What to do? "People have tried to use repellents in the water, but the bees are likely to use the odor as an attractant when attempting to relocate the water source. Some people have had success keeping bees and wasps out of their swimming pools with very lightweight oils or monomolecular films--their purpose is to prevent mosquitoes from being able to breathe. But, if the water is splashed very much, you'll require a new layer."
And all those bees struggling in your swimming pool? "Not all moribund honey bees in a swimming pool are there because they were trying to get a drink. Every day, approximately 1,000 old honey bees from each colony die naturally. This normally occurs during foraging, and the bees just flutter down to the ground, sidewalk, driveway, parking lot, or whatever they were passing over. Some flutter into swimming pools. They are not dead, yet, so they can and do inflict stings on people who bump into them on the surface of the water. "
Beekeepers should make sure there's a watering source on their property so the bees won't hunt for water elsewhere, Musssen pointed out. It should be available all year around. "Once the bees are habituated to the site, most of them will use that source."
It's also a good idea to place corks in a birdbath for the bees to stand on. Bees don't like to get their feet wet. And if they drop into the water structure, they can drown.
As for the bee tenants in our watering hole, bring 'em on.
We absolutely love "The Water Girls." The birds, well, not so much. (But they do have access to a second birdbath and a fish pond.)

If you missed UC Davis distinguished professor James R. Carey's well-attended seminar on "California's Fruit Fly Invasion: A 70-Year Struggle Nears Critical Mass," it's now online on YouTube.
His seminar, which took place June 3 in Briggs Hall, UC Davis, and on Zoom, drew global interest, stretching as far as Australia.
Carey pointed out that Callfornia has "the largest agricultural industry in the United States ($55 billion), is the fifth largest worldwide supplier of agricultural produces, grows more than 200 different crops, and "most fruit crops have been attacked by multiple tephritid species."
The California Department of Food and Agriculture (CDFA) reported that the first Mediterranean fruit fly (medfly) outbreak occurred on June 5, 1980, he said, and as of June 3, the state has detected 18 total species of fruit flies in 350 cities, amounting to 11,000 detections.
In his hour-long seminar, Carey presented an overview of the long-developing crisis, discussed lessons learned from analysis of fruit fly detection databases, and argued that "in order to have any chance at stemming this ever-rising tide, CDFA and the USDA urgently need to switch from their historic, ad hoc eradication strategy to a new one that is evidence-based and far more scientific."
In the closing moments, he asked "Why have oriental fruit fly outbreaks been occurring annually for the past 60 years in California?"
Because, he said, the fruit flies are "permanently established."
Carey, a 44-year member of the UC Davis faculty who is retiring in June, and a senior scholar in the Center for the Economics and Demography of Aging at UC Berkeley, researches insect biodemography, mortality dynamics, and insect invasion biology. He holds a doctorate in entomology from UC Berkeley (1980).
Carey served on the CDFA's Medfly Scientific Advisory Panel from 1987-1994, testified to the California Legislature "Committee of the Whole" in 1990 on the Medfly Crisis in California, and authored the paper "Establishment of the Mediterranean Fruit Fly in California" (1991, Science 258, 457).
He is a fellow of four professional societies: Entomological Society of America, the American Association for the Advancement of Science, the California Academy of Sciences, and the Gerontological Society of America. He is former director (2003-13) of a 11-university consortium funded by the National Institute on Aging (NIH/P01) on the evolutionary ecology of lifespan. He co-authored the book “Biodemography: An Introduction to Concepts and Methods” (Carey, J. R. and D. Roach. 2020; Princeton University Press) and authored the books, “Demography for Biologists (Oxford University Press 1993), Longevity (Princeton University Press, 2003), and Longevity Records: Life Spans of Mammals, Birds, Amphibians and Reptiles (Odense, 2000) as well as more than 250 journal articles and book chapters.

Oh, there ain't no bugs on me
There ain't no bugs on me
There may be bugs on some of you mugs
But there ain't no bugs on me
You can hear it on YouTube.
UC Davis distinguished professor James R. Carey of the Department of Entomology and Nematology, drew national news media coverage in 1991 when he declared that the medflies are "established" here, that the "recurring outbreaks" are not caused by tourists continually bringing infested fruit to California in their airline baggage.
Today Carey says that California's fruit fly invasion is in "crisis mode."
The professor will present a Department of Entomology and Nematology seminar on "California's Fruit Fly Invasion Crisis" at 4:10 p.m., Monday, June 3 in Room 122 of Briggs Hall. It also will be on Zoom. The Zoom link:

"After seven decades of near-continuous outbreaks in scores of California cities, tephritid fruit fly invasions (e.g., Mediterranean, oriental, peach, and Mexican fruit flies) are reaching critical mass, with many of the annual eradication programs morphing into below-the-radar, never-ending fruit fly control programs," Carey says in his abstract. "Permanent establishment of any one of these tropical species has the potential to shut down the multi-billion dollar domestic and foreign markets for hundreds of California fruit and vegetable crops."
"I will present an overview of the long-developing crisis, discuss lessons learned from analysis of fruit fly detection databases, and argue that, in order to have any chance at stemming this ever-rising tide, CDFA and the USDA urgently needs to switch from their historic, ad hoc eradication strategy to a new one that is evidence-based and far more scientific."
