A scientific research project may initially be deemed a failure, but failure can lead to success.
It did recently at the University of California, Davis.
Take the case of the walnut twig beetle, Pityophthorus juglandis, which in association with the canker-producing fungus, Geosmithia morbida, causes thousand cankers disease, which kills walnut trees, especially wreaking havoc on black walnuts.
The late Steve Seybold (1959-2019), a UC Davis-affiliated entomologist and global authority on the insect, fungus and disease, accidentally discovered an insect repellent when he was...

The legacy of chemical ecologist Steven Seybold thrives with the recent publication of two papers by two of his UC Davis students.

We are all saddened by the death of noted forest entomologist and chemical ecologist Steven Jon Seybold, a lecturer and researcher with the UC Davis Department of Entomology and Nematology and a research entomologist with the Pacific Southwest Research Station, USDA Forest Service, Davis.
Steve passed away Friday, Nov. 15 at a Sacramento hospital of a heart condition. Born in 1959 in Madison, Wisconsin, he was 60 years old. He was one of the pioneering scientists researching the newly discovered thousand cankers disease (TCD), caused by the walnut twig beetle, Pityophthorus juglandis, in association with the canker-producing...

Forest health promises to take a turn for the better, thanks to forest entomologists like Jackson Audley, a doctoral student at the University of California, Davis.
Audley just received the 2019 Western Forest Insect Work Conference (WFIWC) Memorial Scholarship Award for his research on the chemical ecology of an invasive bark beetle, the walnut twig beetle.
Audley, who conducts his research in a commercial orchard near Winters, investigates behavioral chemicals that repel the walnut twig beetle from landing on English walnut trees. The walnut twig beetle (Pityophthorus juglandis), in association with a canker-producing fungus, Geosmithia morbida, causes the...
