Polyphagous shot hole borer and Fusarium dieback, an emerging exotic pest/disease complex causing dieback throughout agricultural, urban, and wildland landscapes in Southern California
Wednesday May 4th, 10:30 am, Urban Forestry/Risk Breakout (Main Street USA)
The polyphagous shot hole borer (PSHB) is an invasive ambrosia beetle that forms a symbiosis with multiple fungi. Together, they cause fusarium dieback (FD), a pathogen/insect complex that affects trees in agriculture, ornamental landscapes, and native forests in California. Since early 2012, FD has been confirmed on more than 138 species of tree in landscape and urban forest in Los Angeles, Orange, Riverside and San Bernardino and San Diego counties.
Akif Eskalen is a plant pathologist and extension specialist in the Department of Plant Pathology and Microbiology at UC Riverside. His research focuses on identification, biology, epidemiology and control of pathogens associated with subtropical crops in California, including new potential threats, and addresses how these pathogens interact to contribute to subtropical crop decline. Currently, Akif is studying on biology, epidemiology and botanical host range of Fusarium Dieback pathogens associated with Polyphagous shot hole borer in California.
