Medical entomologist-geneticist Geoffrey Attardo, associate professor, UC Davis Department of Entomology and Nematology and chair of the Designated Emphasis in the Biology of Vector-Borne Diseases (DEBVBD),  will speak on tsetse flies at the next department seminar, set for 4:10 p.m., Monday, Oct. 9 in 122 Briggs Hall.

Attardo will discuss “The Mating Biology of Tsetse Flies--Insights into the Morphological, Biochemical, and Molecular Responses to Mating Stimuli in a Viviparous Disease Vector.”

"Research into the reproductive behavior of tsetse flies offers key insights into controlling diseases like African sleeping sickness," he 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:

The Attardo lab monitors the dynamics of vector insects at the levels of physiology, population genetics and environmental interactions. 

Attardo 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.

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. 

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.

If you've been following the breaking news about the invasive mosquito, Aedes aegypti, detected recently in Yolo, Solano and Sacramento counties--you can learn more about these disease-carrying mosquitoes at the Bohart Museum of Entomology open house on Saturday afternoon, Sept. 23.

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.

CC Edwards. In the Attardo lab, CC 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."

"I went on to do my masters at Texas Tech University under the advisement of Dr. Corey Brelsfoard where I graduated this past summer (2023)," she said. "I investigated the effects of microplastics in relation to the mosquitoes Aedes aegypti and Aedes albopictus (the Asian tiger mosquito). Plastic pollution has been a worldwide problem and research has shown that microplastics have been found in the guts of various organisms. With Aedes species being container inhabiting species, my master's research was focused on investigating if there are alterations of the mosquitoes' microbiomes and their immunity due to the ingestion of microplastics." 

"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.

Moriah Garrison. Moriah, who joined CLBR more than five years ago, manages a wide variety of studies, including experimental design and hands-on entomology. She received her bachelor's degree in entomology from UC Davis in 2020 and is pursuing a master's degree in entomology with a specialization in medical entomology from the University of Florida. A former UC Davis laboratory manager in applied insect ecology, she worked as a field researcher with the Pollinator Partnership for two years.  

CLBR, involved in insect repellent testing and natural product development, is  owned and managed by scientists Scott Carroll and Jenella Loye, a husband-wife team affiliated with UC Davis Department of Entomology an Nematology. Formed in 1989, the company  serves the consumer products industry with testing, development and regulatory services for insect repellents, organic products, and low toxicity pesticides. Carroll, president of CLBR, is an evolutionary biologist, while Loye is a medical entomologist and microbiologist.  Carroll holds a doctorate in biology/biological sciences from the University of Utah, while Loye holds a doctorate in zoology, microbiology and epidemiology from the University of Oklahoma.

Photography Displays. 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 (DEBVBD), will display some of his mosquito images, including a blood-fed Aedes aegypti, and a female and male Culex tarsalis. Alex Wild,  a UC Davis doctoral alumnus and curator of entomology, University of Texas, Austin, will display an image of mosquito larvae that currently hangs in Briggs Hall, home of the UC Davis Department of Entomology and Nematology. Wild's insect images can be viewed on his website,  https://www.alexanderwild.com.

Petting Zoo. A popular attraction is the live petting zoo; visitors are encouraged to hold or get acquainted with live Madagascar hissing cockroaches and stick insects.

Family Arts and Crafts Activity. The event will be held outside and will highlight two collecting techniques, said Tabatha Yang, education and outreach coordinator. 

1. Clear Packing Tape Art. "Clear packing tape is a good way to collect small, hard-to-see insects," Yang said. "Glitter will mimic small insects like fleas or bed bugs. Putting the tape on white paper makes it easy to look at them under a microscope and for this craft it will make a pretty card."
2. Making insect collecting or "kill" jars. 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. 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.

What do you think of when someone mentions "household vampires?"

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.
