$3 Million Grant Awarded to Study Causes, Impact of Grapevine Virus
University of California, Davis, scientists will lead a collaborative effort to study grapevine red blotch disease, which threatens the $162 billion U.S. grape industry. The virus causes red veins and blotches on grape leaves. The fruit on diseased plants is smaller, ripens more slowly, and its sugars and colors are muted.
Sixteen UC Davis researchers have been named in the annual Highly Cited Researchers 2019 list released by the Web of Science Group, which compiles statistics on scientific publishing. The list identifies scientists and social scientists who have published multiple papers ranking in the top 1 percent by citations in a particular field and year, over a 10-year period.
Citation counts represent how often a particular paper has been cited in other scientific publications.
UC Davis researchers included in this year’s list are:
Strawberry growers now have a free smart phone application tool to predict spray coverage to combat such pests as two-spotted spider mites, lygus bugs and leafrollers, thanks to a three-year collaborative project involving UC Davis agricultural entomologist Christian Nansen and several UC Davis computer science majors.
Many people set up hummingbird feeders in their yards to nurture and watch these high-energy pollinators. But could the sugar water they provide be impacting these tiny feathered friends?
A study led by the University of California, Davis, is one of the first to address the potential for sugar water from hummingbird feeders to act as a vector for avian — or even zoonotic — pathogens. It found that the majority of microbes growing in feeders do not likely pose a significant health hazard to birds or humans.
The Department of Entomology at UC Davis began as an offshoot of the Department of Entomology and Parasitology at UC Berkeley. Entomology at Davis was closely entwined with the department at Berkeley for more than 50 years before it separated and became autonomous. Much of this early record is fascinating and it demonstrates how entomology has always been an integral part of teaching, research and extension on the Davis campus—in effect the department and the campus came of age together.
UC Davis entomology professor Frank Zalom receives national award
Frank Zalom, an integrated pest management (IPM) specialist and distinguished professor of entomology, is the recipient of the 2017 B.Y. Morrison Medal, established in 1968 by the U.S. Department of Agriculture/Agricultural Research Service (USDA-ARS). He is the first entomologist to receive the award.
Ron Tjeerdema named to NAS committee on dispersants for oil spills
Ronald Tjeerdema, CA&ES Associate Dean for Environmental Sciences, has been named to a select committee for the National Academy of Sciences (NAS) that will evaluate the use of dispersants in future oil spills.
“I am looking forward to contributing my 30 years of experience in oil spill research,” said Tjeerdema, who is a professor in the Department of Environmental Toxicology and also holds the Donald G. Crosby Endowed Chair in Environmental Chemistry.
Three to be honored at May 2 reception for outstanding student advising
Emma Martinez, Louie Yang, and Carly Tyer are the 2017 recipients of the Harry and Eleanor Walker Academic Advising Award. They will be honored at a reception May 2 at the Robert Mondavi Institute Sensory Theater.
Farms with more variety of crops attract fewer insect pests
Left to its own defenses, a farm field growing a variety of plants tends to attract fewer insect pests than a field growing just one type of crop. While scientists and farmers have noted that difference for years, the reasons behind it have been poorly understood.
A Sacramento company that turns food waste into liquid fertilizer has launched a three-year almond trial at UC Davis to test the product’s effect on crop production, nitrogen leaching, and soil health.
Working with Professor Edwin Lewis with the UC Davis Department of Entomology and Nematology, California Safe Soil is also conducting ongoing trials throughout the state with several other commodities, including berries, lettuce, and tomatoes.
