Red Blotch Disease Makes Cover of JournalFrank Zalom and research biologist Mysore "Sudhi" Sudarshana of the USDA's Agriculture Research Services (ARS), is featured as the cover story of this month's special focus issue, "Disease Management in the Genomics Era," in the journal Phytopathology.
The cover features a photo of feeding injury caused by the three-cornered alfalfa hopper, Spissistilus festinus. Last year the Zalom team hypothesized that the three-cornered alfalfa hopper could transmit the Grapevine red blotch-associated virus, GRBaV, based in part on phylogeneic analysis of coat protein sequences of 23 geminiviruses that revealed that GRBaV-CP was most similar to that of another geminivirus that was transmitted by another treehopper. Their research, published in the journal, confirmed that the alfalfa hopper “was able to both acquire the virus from a grapevine infested with GRBaV and transmit the virus to healthy grapevines in the laboratory.” -more-
Retreat for Faculty, Graduate Students
Faculty and graduate students with the UC Davis Department of Entomology and Nematology--and others associated with an ENT/NEM lab--got together for a retreat, held Friday, Oct. 14 through Sunday, Oct. 16 at Sagehen Creek Field Station in Truckee.
Doctoral candidate (and photographer) Sandy Olkowski shared some of her photos of the activities, including insect collecting and dinner preparation. She also took s photo of deer at the campsite. -more-
Unique Honey Tasting Event Oct. 20Honey and Pollination Center at the Robert Mondavi Institute, UC Davis,
Featured honeys are hard-to-find almond, savory coriander, fruity pomegranate and our ever-changing Northern California wildflower. Each honey will be paired with its produce: almonds, cilantro and pomegranate seeds. As a special treat, the wildflower will be combined with a creamy cheese so participants can discover how honeys change with different foods.
Extension apiculturist Elina Niño will deliver a short talk on the state of the bees in California and the country with a focus on the almond pollination season.
Cost is $30 (general), $25 (UC Davis affiliates), $12.50 (students). Register here: https://registration.ucdavis.edu/Item/Details/254
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-
Marvin Goodrow: 1930-2016
Dr. Goodrow joined the environmental diagnostics group in the Entomology Department and participated in the inaugural UC Davis/National Institute of Environmental Sciences (NIEHS) Superfund Research and Training Program, an interdisciplinary program directed by Bruce Hammock, distinguished professor in the Department of Entomology and Nematology. The program was formed 30 years ago.
“Marvin was proud to have worked with Donald Cram who won the Nobel Prize in 1987,” Hammock recalled. “He carried out key organic chemistry for preparation of numerous immunoassays for pesticides and other environmental contaminants. He was an enthusiastic mentor of young scientists.” -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-
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-
List of Departmental Seminars
"My research explores the intricacies of plant-pest (insect/pathogen) interactions in the context of forest health," he says. "The specialized interactions between plants and pests offer opportunities to explore defense mechanisms and identify traits (physical/chemical) such as underlying genes, biochemical pathways, proteins, and phytochemicals involved in plant protection."
During his Ph. D. research at The Ohio State University and as a postdoctoral fellow at the University of British Columbia, he successfully applied an integrated approach to deciphering plant-insect interactions in important forest tree species.
A list of the department's 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.
