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.

During the initial throes of the Mediterranean fruit fly invasion in California, protesters disagreeing with the California Department of Food and Agriculture's eradication procedures and policies used to sing the catchy tune, "There Ain't No Bugs on Me," the work of Jerry Garcia and David Grisman.

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."

A noted authority on California's tropical fruit fly invasion says the state is in "crisis mode."

"It's really serious," says UC Davis distinguished professor James R. Carey, a noted authority on the invasion of tropical fruit flies.

Professor Carey will discuss his findings at a UC Davis Department of Entomology and Nematology seminar at 4:10 p.m., Monday, June 3 in Room 122 of Briggs Hall. His seminar, titled "California's Fruit Fly Invasion Crisis," also will be on Zoom. The Zoom link:

If you've ever seen the nests of the bindweed turret bees, Diadasia bituberculata, and if you've ever tried to photograph these fast-flying bees, you know how speedy they are and how difficult they are to photograph.

So when we viewed KQED's Deep Look video,  “This Fly Torpedoes a Bindweed Bee's Nest,” on YouTube at https://youtu.be/gJHCoP4WqMc, we were totally amazed. It's nothing short of spectacular.

The crew filmed the bees in a nesting area outside the UC Davis Stebbins Cold Canyon Reserve, near Winters. 

UC Davis scientists Shawn Christensen, a fifth-year doctoral candidate in the laboratory of community ecologist Rachel Vannette, UC Davis Department of Entomology and Nematology, were among those collaborating with the Deep Look production. 

“Shawn has done a lot of work on this bee and with Deep Look, and he also leads our lab's work on Anthophora bomboides, a bumble bee mimic, and studies microbial associates of pollen and solitary bees,” said community ecologist and associate professor Rachel Vannette, a Chancellor's Fellow and vice chair of the Department of Entomology and Nematology.

The bees, also known as digger bees or chimney bees, are specialists on bindweed, commonly known as morning glory.  “The females use pollen only from one plant species and are active through the late spring and early summer,” said Vannette, an international leader in microbial ecology who studies interactions between plants, insects and microbes.

Native to California, the bindweed turret bees dig underground nests, many with structures called turrets at the nest entrance. They provision the nests with pollen for their future offspring, and then lay their eggs inside.    

Gabriela Quirós, coordinating producer of Deep Look and producer of this video,  consulted with the UC Davis scientists, obtaining information on the location of the bee nests, as well as information on the brood cells, pollen, and turrets. The Deep Look production includes UC Davis images taken inside a bee nest. 

Quirós also consulted with seven other scientists: Stephen Buchmann, University of Arizona; Andy Calderwood, Ventura County Deputy Agricultural Commissioner;  Neal Evenhuis, Bishop Museum of Honolulu, Hawaii; Paul Havemann, UC Davis Natural Reserve System; Keng-Lou James Hung,  University of Oklahoma; Doug Yanega, UC Riverside, and James Carey, a naturalist who researches and videos bindweed turret bees in the Santa Monica Mountains National Recreational Area. 

 Josh Cassidy, the lead producer and cinematographer, filmed all the footage except for the male bees fighting with each other (00;17;14- 00;25;22 in the video).  James Carey, who filmed that incredible footage, “has been regularly monitoring and filming bindweed turret bees since 2016 in Rancho Sierra Vista/Satwiwa, an open space in the Santa Monica Mountains,” Quirós said. “James also filmed the shot at 04;17-04;21 showing nests in the Santa Monica Mountains covered up at the end of the nesting season."

Christensen, a member of the UC Davis Microbiology Graduate Group and anticipating his doctorate in the spring of 2024, is an evolutionary biologist turned microbiologist. Christensen also researches other native bees,  including Melissodes and Colletes.

Vannette focuses her research on the chemical and microbial ecology of plant-pollinator interactions and how microbes influence plant defense and resistance against insect pests.  On its website, the Vannette lab is described as "a team of entomologists, microbiologists, chemical ecologists, and community ecologists trying to understand how microbial communities affect plants and insects--sometimes other organisms, too. We often study microbial communities in flowers, on insects or in soil. We rely on natural history observations, and use techniques from chemical ecology, microbial ecology and community ecology.  In some cases, we study applied problems  with an immediate application including pathogen control or how to support pollinators.”

We're looking forward to more research from the Vannette lab, including their work on Anthophora bomboides, a bumble bee mimic that forms turrets in sand dunes (including the sand cliffs at Bodega Head).

Most people are unaware that there are more than 20,000 known bee species in the world, and 4,000 of them are native to the United States. Of the 20,000 known bee species, 70 percent are ground-nesting bees. California alone is home to more than 1600 species.

And just one of those species is the bindweed turret bee, Diadasia bituberculata, that forages on morning glories. Glory bee...
