The Curious Life of California Oak Gall Wasps

Using long fruit pickers, a UC Davis research team fans out along Putah Creek, plucking the tiny homes of gall wasps from the branches of oak trees. These small, round growths, created by California oak gall wasps, protect their larvae. In the lab, researchers are raising the insects and searching for clues about this cryptic species that’s all around yet rarely noticed.

Student Entomologists Gain Hands-On Skills in Insect Biology

Distinguished Professor of Entomology Jay Rosenheim noticed a trend during his office hours a few years ago: Many of his undergraduate students wanted research lab experience but were unsure how to get started. Alongside colleagues Louis Yang and Joanna Chiu, they collectively decided to try something different in 2011.

“Our basic idea was to get students into the labs really early in their undergraduate programs,” Rosenheim recalled. “There’s a whole new set of skills that are very different from what students are typically working on in their formal coursework.”

UC Davis Bohart Museum of Entomology Welcomes New Director with Spider Expertise

Professor Jason Bond starts today (Feb. 1) as the new director of the UC Davis R.M. Bohart Museum of Entomology, which houses the 7th largest insect collection in North America. Bond succeeds Lynn Kimsey, distinguished professor with the Department of Entomology and Nematology, who retired last month after serving as the museum’s director and curator since 1990.

CA&ES Departments Welcome Newly Appointed Chairs

UC Davis Professors Joanna Chiu and Andrew Whitehead have been appointed as the new chairs of the Departments of Entomology and Nematology and Environmental Toxicology, respectively. Mary Delany has also been appointed as interim chair for the Department of Human Ecology. As the academic year gets underway, these visionary leaders are set to steer their departments toward groundbreaking research, interdisciplinary collaborations and exceptional experiences for students.

Snack Maker Makes Donation to Continue Bee Health Research at UC Davis

Bees play a critical role in California’s agricultural ecosystems by pollinating many important crops, including almonds. Climate change, habitat loss, pesticides and other factors pose problems for bee populations.

To date, KIND Snacks has donated $350,000 for bee research at UC Davis, led by Entomology Professors Neal Williams and Elina Niño for continued research on bee health. California grows the vast majority of the world’s almonds, which rely on bees and other pollinators.

Pesticides Can Affect Multiple Generations of Bees

A new study from researchers at the University of California, Davis, finds that pesticides not only directly affect bee health, but effects from past exposure can carry over to future generations. The study, published in the journal Proceedings of the National Academy of Sciences, suggests that bees may require multiple generations to recover from even a single application.

Pesticides and Food Scarcity Dramatically Reduce Wild Bee Population

Study Finds 57% Drop in Reproduction When Exposed to Both Threats

The loss of flowering plants and the widespread use of pesticides could be a double punch to wild bee populations. In a new study, researchers at the University of California, Davis, found that the combined threats reduced blue orchard bee reproduction by 57 percent and resulted in fewer female offspring. The study was published in the journal Proceedings of the Royal Society B.

CA&ES scientists are among the winners of Chancellor’s Innovation Awards

A team of scientists affiliated with the UC Davis Foods for Health Institute and entomology professor Bruce Hammock are among the recipients of the 2020 Chancellor’s Innovation Awards, which recognize faculty, project teams and community partners for their work, dedication and success in improving the lives of others and addressing the needs of society.

 

Grapevine Red Blotch Disease Threatens U.S. Grape Industry

$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.
