Two little beetles, the Polyphagous and Kuroshio Shot Hole Borers, are attacking common native and landscaping trees in our neighborhoods, parks and open spaces. These tiny beetles bore into the trees and spread a fungus, Fusarium euwallaceae, that interferes with the distribution of water and nutrients, resulting in a disease called Fusarium Dieback. The beetles can lay their eggs and grow Fusarium in 36 known species.
The Polyphagous Shot Hole Borer/Fusarium Dieback (PSHB/FD) and Kuroshio Shot Hole Borer/Fusarium Dieback (KSHB/FD), are a non-native beetle-fungi complex that have invaded Southern California and are currently threatening tens of thousands of trees throughout the region. This invasive species complex is quickly reaching epidemic proportions and has widespread environmental, economic, and aesthetic implications for the region.
Dr. John Kabashima, our January '4th Tuesday' Conservation Lecturer, will review the history of the complex in Southern California, current research, potential responses and agricultural, urban forest and riparian management issues. His talk will include information on how we can recognize the presence of the invasive beetle and how to reporto a suspected tree.
Dr. Kabashima has a PH.D. in Entomology and an M.S. in Pest Management from UC Riverside, an M.B.A from Pepperdine and a B.S. in Agricultural Biology from California Polytechnic University at Pomona. In addition to his position as Environmental Horticulture Advisor, Dr. Kabashima served as interim Center Director of the UC Agriculture and Natural Resources South Coast Research and Extension Center (SCREC) in Irvine and as the County Director of the UCCE in Orange County. He is currently working on the Polyphagous Shot Hole Borer/Fusarium Dieback as an Emeritus Advisor.
Please join us. Doors open at 7:00 for snacks and social. The program starts at 7:30. We hope to see you there.
