James Carey to Deliver Major Presentation at ICE Conference
Carey is the world’s foremost authority on arthropod demography. He has authored more than 250 scientific articles, including landmark papers in Science that shaped the way scientists think about lifespan limits and actuarial aging, and two articles in the Annual Review series that provide new syntheses on insect biodemography. Co-chair of ICE is UC Davis chemical ecologist Walter Leal. See ICE schedule.
The Entomological Society of America (ESA) is hosting ICE. The ESA annual meeting is typically scheduled every November; however, for 2016, ESA's meeting events will take place during ICE 2016. UC Davis graduate students will compete in the ESA's Linnaean Games, a college-bowl type event focusing on insects and entomologists. The team, captained by Ralph Washington Jr., also includes Brendon Boudinot and Emily Bick.
Bruce Hammock: FDA's Ban on Triclosan, 'Story with a Good Ending"Bruce Hammock who sounded the alarm about triclosan with several other scientists funded by the National Institute of Environmental Health Sciences (NIEHS), says the U.S. Food and Drug Administration's recent ban of 19 over-the-counter antibacterial chemicals, including triclosan and trilocarban, is the right thing to do.
Triclosan and trilocarban are widely used antibacterial chemicals found in cosmetics, soaps, shampoos, toothpastes, body washes and many other household products.
Hammock initiated the work on triclosan through the NIEHS/UC Davis Superfund Program that he directs, pulling together researchers from multiple colleges on campus, including the College of Agricultural and Environmental Sciences, School of Veterinary Medicine and the School of Medicine. -more-
Malaria Mosquito's Host Choice Linked to Genetic Component
The research, published in the Sept. 15 edition of PLOS Genetics, involved the study of Anopheles arabiensis, in Kilombero Valley in Tanzania. The mosquito is the primary vector of malaria in east Africa.
"We know that blood feeding preference among mosquitoes can be species specific,” said co-author and professor Greg Lanzaro, who leads the Vector Genetics Laboratory, UC Davis Department of Pathology, Microbiology and Immunology and is an affiliate of the UC Davis Department of Entomology and Nematology. “For example, there are mosquito species that specialize in feeding on amphibians or reptiles. We also know that many species are more catholic when choosing a meal and this can have important implications to human health—it's how some disease agents move between animals and humans.” -more-
Use Antimicrobials Wisely--Scott CarrollScott Carroll.
In a paper titled “Use Antimicrobials Wisely,” published in the current edition of Nature, a nine-member international research team, including Carroll, advocates that the United Nations reframe its action on antimicrobial resistance.
The United Nations met Sept. 21 in New York to discuss the global antimicrobial drug resistance (AMR) crisis.
“We're concerned about what will happen if the proposed UN solutions focus mainly on incentives for new drug development, at a time when the drug industry itself is abandoning those efforts against infectious disease due to AMR,” said Carroll, who co-leads the international group on resistance to pesticides and antimicrobial drugs. He founded and directs the Institute for Contemporary Evolution, Davis, and is a member of the Sharon Lawler lab, UC Davis Department of Entomology and Nematology. -more-
UC Davis Honey and Pollination Center Helping Students
Two UC Davis entomology graduate students, Patricia Bohls and Maureen Page, have each received a $6700 stipend, thanks to philanthropic donations and the UC Davis Honey and Pollination Center's efforts to support students engaged in research, teaching and outreach. Bohls, who is seeking her doctorate in entomology, with a focus on honey bee queen rearing and health, studies with Extension apiculturist Elina Niño. Originally from Macedonia, Ohio, Bohls received her bachelor's degree in neuroscience and environmental studies at Hiram (Ohio) College. Page, who began her graduate students this fall with pollination ecologist Neal Williams, associate professor of entomology, is exploring pollinator communities in response to agricultural management and the benefits of providing diverse floral habitat. She completed her undergraduate work at Scripps College, Claremont, Calif. -more-
Systemic Insecticides May Not Work as Well During Drought--Christian NansenChristian Nansen.
“Weather patterns associated with climate change may adversely affect the performance of some of the most important insecticides, systemic insecticides, against coleopteran and lepidopteran pests,” Nansen says.
“These insecticides depend on efficient water and nutrient uptake through the root system and on vascular flow – both mechanisms may be partially compromised under drought conditions,” Nansen points out. “This leads to lower uptake and non-uniform distribution of systemic insecticide in plant tissues – and therefore, higher risk of pests NOT acquiring a lethal dosage.” -more-
Three Receive Hazeltine Student Research Awards
For the second consecutive year, UC Davis graduate students Sandy Olkowski, Stephanie Kurniawan and Maribel "Mimi" Portilla are recipients of the Bill Hazeltine Student Research Awards, memorializing a medical entomologist who worked tirelessly in mosquito research. The three recently lunched at a Davis restaurant with Hazeltine's sons, Craig of Scottsdale, Ariz.,and Lee Hazeltine of Woodland. The graduate students discussed their research and goals and thanked them for the Hazeltine family's support. -more-
UC Davis Toxicologist Shirley Gee: 40 Years of Service
If you preface her name with “research scientist” or “renowned toxicologist,” followed by “40 years of service at UC Davis,” those words don't even begin to describe her or her work.
Shirley Gee, principal investigator, lecturer, mentor and the longtime manager of the Bruce Hammock research lab, UC Davis Department of Entomology and Nematology, retired June 30, leaving a long chain of accomplishments, admiration, appreciation and affection extending locally, nationally and globally.
Gee, who joined the Hammock lab in 1985, managed a team of researchers that annually included some 40 scientists: graduate students, technicians, post graduates and visiting professors from all over the world.
“Forty seems like a crazy big number,” Gee said, “and I am a little overwhelmed by it (the number).” -more-
Next Seminar Speaker: Meredith Cenzer
Soapberry bugs are a classic evolutionary example of how rapidly insects can switch hosts, adapting from a native to an invasive plant, she says.
Her newly published UC Davis research shows that soapberry bugs have not only lost adaptations to their native host plant but are regionally specializing on an invasive host. -more-
A list of the fall seminars through Nov. 30, is here. All will take place on Wednesdays from 4:10 to 5 p.m. in 122 Briggs Hall. This is a change from the previous noon-hour seminars.
Lester Ehler: 1946-2016
"Dr. Ehler had a remarkable career at UC Davis,” said Steve Nadler, professor and chair of the UC Davis Department of Entomology and Nematology. “In his research he built upon fundamental investigations in integrated pest management (IPM) to provide practical biological control for many different systems. Les was both a national leader in the discipline of biological control, and an outstanding citizen of the department and university.”
Dr. Ehler, who joined the UC Davis Department of Entomology in 1973 and retired in January 2008, was the first biological control specialist on campus and was known as the “quintessential biological control researcher.”
For four decades he championed the use of natural enemies to control agricultural pests and warned of the dangers of pesticides. -more-
