The goal is "to advance the land management aims of local tribal communities and provide a platform to educate about the importance of maintaining wetland biology for climate change, ecological and human health, and vector control,” announced medical entomologist-geneticist Geoffrey Attardo, associate professor, UC Davis Department of Entomology and Nematology.
The symposium is sponsored by the UC Davis Department of Entomology and Nematology and the Pacific Southwest Center of Excellence in Vector-Borne Diseases, which aims to “strengthen the capacity to prevent and respond to emerging vector-borne diseases in the southwestern United States and Pacific Islands.”
His collaborator is Diana Almendariz, a traditional ecological knowledge specialist and a cultural practitioner of Maidu/Wintun,Hupa/Yurok traditions, heritage, and experiences. She will discuss the precolonial relationships between native peoples and wetlands in Northern California, the impacts of colonization on those relationships, and the application of traditional ecological knowledge practices to restore damaged wetland ecosystems. (See video of her talking about her goals at https://www.youtube.com/watch?

He's been planning "Tule and Cattail: A Tale of the Marsh Economy and Its Role in Human Health and Wellbeing” for a year. Sponsored by ENT and the Pacific Southwest Center of Excellence in Vector-Borne Diseases, it's free and family friendly. You can register at https://qr.codes/xYbeAK.
What a great day to spend a Sunday afternoon--and on St. Patrick's Day, too.
Attardo, both a talented scientist and photographer, has been capturing lots of images in the wetland area in Cache Creek conservatory which is adjacent to the Tending and Gathering Garden. "The wetland area is flooded by runoff from the Gordon Slough and is a habitat to plants and animals native to Northern California," says Attardo, chair of the UC Davis Designated Emphasis in the Biology of Vector-Borne Diseases. "The islands in the wetland are populated with tule which is a hardstem bulrush. Tules provide shelter to an array of wildlife. Red-winged blackbirds commonly build their nests in tule stalks. Reptiles and amphibians also live among them. Dragonflies frequently use tule stalks for eclosion and as perches. Fish also use the submerged stalks and root systems as nurseries."
"The tule acts as a water filter by sequestering excess nutrients from the water in collaboration with symbiotic microbes," he commented. "The tule also stabilizes the banks and slows waterflow. The tule is also utilized by native peoples for a variety of purposes including making sleeping mats, baskets, cordage, external and internal walls for homes, canoes. It also functioned as a food source."
Basically, it's a collaborative outreach project "to integrate indigenous ecological knowledge and Western science to provide educational outreach opportunities."
The aim: "to advance the land management aims of local tribal communities and provide a platform to educate about the importance of maintaining wetland biology for climate change, ecological and human health, and vector control," Attardo says.
Here's what's on the agenda (note that the symposium will start promptly at 1 p.m. Snacks and drinks will be provided.)

That's just one of the facts that UC Davis medical entomologist-geneticist Geoffrey Attardo will discuss when he presents a seminar on "The Mating Biology of Tsetse Flies--Insights into the Morphological, Biochemical, and Molecular Responses to Mating Stimuli in a Viviparous Disease Vector."
The seminar, hosted by the UC Davis Department of Entomology and Nematology, is set for 4:10 p.m., Monday, Oct. 9 in 122 Briggs Hall.
Attardo, an associate professor, UC Davis Department of Entomology and Nematology and chair of the Designated Emphasis in the Biology of Vector-Borne Diseases, is a global expert on vectorborne diseases, including his groundbreaking work on tsetse flies. He researches the invasive yellow mosquito, Aedes aegypti, which can carry such diseases as dengue, chikungunya, Zika and yellow fever.
His work involves predicting insecticide resistance and tracking movements of genetically independent populations of aegypti throughout the state.
"Research into the reproductive behavior of tsetse flies offers key insights into controlling diseases like African sleeping sickness," Attardo writes in his abstract. "Unique among insects, these flies give birth to live offspring. During mating, males transfer a mix of sperm and other vital substances to the females. This study employs state-of-the-art techniques, including 3D scanning and genetic analysis, to monitor changes in the female fly's reproductive system over a 72-hour period post-mating. Findings indicate that mating sets off a chain of intricate changes in the female, affecting everything from biochemistry to gene activity. These changes prepare her for pregnancy and childbirth. The study opens up new avenues for understanding tsetse fly biology and offers potential strategies for disease control."
The seminar also will be on Zoom. The link:
https://ucdavis.zoom.us/j/95882 849672
The Attardo lab monitors the dynamics of vector insects at the levels of physiology, population genetics and environmental interactions.
Attardo, who holds a doctorate in genetics from Michigan State University, where he researched the molecular biology of mosquito reproduction, joined the UC Davis Department of Entomology and Nematology in 2017 from the Yale School of Public Health's Department of Epidemiology of Microbial Diseases.
For his outstanding work, he received the 2022 Medical, Urban, and Veterinary Entomology Award from the Pacific Branch, Entomological Society of America, which encompasses 11 Western states, plus parts of Canada and Mexico, and U.S. territories.

The open house takes place from 1 to 4 p.m. in Room 1124 of the Academic Surge Building, 455 Crocker Lane, UC Davis campus. The theme: "Household Vampires." The event will zero in on mosquitoes, fleas, ticks, lice and bedbugs. Scientists will be there to answer questions. The event is free and family friendly and parking is also free.
Who's talking about mosquitoes?
- Educators from the Sacramento-Yolo Mosquito and Vector Control District. See https://www.fightthebite.net/
- Carla-Cristina "CC" Melo Edwards, a first-year doctoral student in the laboratory of medical entomologist-geneticist Geoffrey Attardo, associate professor of entomology, UC Davis Department of Entomology and Nematology. She will share her expertise on mosquitoes and show specimens.
- Moriah Garrison, senior entomologist and research coordinator with Carroll-Loye Biological Research (CLBR). She is scheduled to show live ticks and mosquitoes and field questions.
- Nazzy Pakpour, UC Davis alumna, Novozymes scientist and author of Please Don't Bite Me
Professor Attardo, who maintains a lab website on Vector Biology and Reproductive Biology at http://attardo-lab.com, and chairs the Designated Emphasis in the Biology of Vector-Borne Diseases, will display some of his mosquito images, including a blood-fed Aedes aegypti, and a female and male Culex tarsalis. (A prior commitment prevents him from being at the open house the entire time.) One or more images by Alex Wild, a UC Davis doctoral alumnus and curator of entomology, University of Texas, Austin, also will be featured.
Breaking news? The Aedes aegypti mosquito, which can transmit such diseases as Zika, yellow fever, dengue, chikungunya and others, was detected Sept. 11 in Dixon. "The mosquito may be active around dusk and dawn but bites most often during the day and often bites indoors," said Richard Snyder, Solano County Mosquito Abatement District manager, in a news release.
The Sacramento-Yolo Mosquito Vector Control District recently announced two fatalities in Sacramento and Yolo counties due to West Nile virus. "In addition to these deaths, currently there are 10 other human cases in Sacramento County and 8 in Yolo County. Since there won't be a significant decline in mosquito populations until mid-October, more human cases will likely be reported."
UC Davis distinguished professor Lynn Kimsey, director of the Bohart Museum and UC Davis forensic entomologist Robert Kimsey will be among the presenters on other "household vampires."
Attendees can see the Bohart's butterfly collection, curated by entomologist Jeff Smith, and get acquainted with critters in the live insect petting zoo.
The family arts and crafts activity will feature collecting activities. Participants are asked to bring a recycled jar. "This should be a clean and dried glass jar with a wide, metal top--think jam, pickle, peanut butter jars. Four to 16-ounce jars work well," said Tabatha Yang, education and outreach coordinator. "We will have some on hand as well, but recycling is good! We will fill the bottom with plaster of paris and let it dry and teach people how to use it properly, using something like nail polisher remover containing ethyl acetate as the killing agent.

Fleas? Ticks? Bed bugs? Mosquitoes?
Yes!
The Bohart Museum of Entomology will host an open house, themed "Household Vampires," from 1 to 4 p.m., Saturday, Sept. 23 in Room 1124 of the Academic Surge Building, 455 Crocker Lane, UC Davis campus. It's free and family friendly. Parking is also free.
One of the presenters ready to answer your questions about mosquitoes is Carla-Cristina "CC" Melo Edwards, a first-year doctoral student in the laboratory of medical entomologist-geneticist Geoffrey Attardo, associate professor of entomology, UC Davis Department of Entomology and Nematology, who also specializes in reproductive physiology and molecular biology.
In the Attardo lab, Edwards focuses her research "on investigating the physiological mechanisms underlying pyrethroid resistance in Aedes aegypti (the yellow fever mosquito)."
She was a McNair scholar at Baylor University, where she completed her undergraduate degree in cell and molecular biology in May 2021. "I got interested in the mosquito field through my undergraduate research of studying the sensory and oviposition responses of Aedes aegypti in relation to the compound geosmin," Edwards related.
"When I am not in the lab, I enjoy getting involved with my local community by helping out and doing outreach," Edwards said. This past summer she helped the city of Lubbock, Amarillo, and the Texas Public Health Department by identifying mosquitoes for West Nile surveillance. She also served as the outreach chair for the Texas Tech Association of Biologists during her masters' degree pursuit and enjoyed being a mentor for first-generation students.
"In my free time, I like getting coffee with my friends, running (currently training for the California International Marathon), and trying new crafts and recipes."
Attardo will be displaying images of mosquitoes. An image of mosquito larvae by UC Davis doctoral alumnus and macro photographer Alex Wild, curator of entomology at the University of Texas, also will be displayed.
Open house attendees can view the butterfly specimen collection, curated by entomologist Jeff Smith, and get acquainted with live Madagascar hissing cockroaches and stick insects, part of the Bohart Museum's insect petting zoo. A family arts-and-crafts activity is also planned.
The Bohart Museum, founded in 1946, houses a global collection of eight million insect specimens. It also maintains an insect-themed gift shop. UC Davis distinguished professor Lynn Kimsey, a UC Davis alumna, directs the museum.
