The most recent discovery of invasive shothole borer-pathogen complex in Santa Cruz County has been identified as a different species of beetle and symbiotic fungi than the two complexes previously known in California.
The authoritative source for current knowledge of ISHB/FD is the UC IPM Pest Note on Invasive shothole borers (ISHB), authored by Beatriz Nobua-Behrmann, UC Cooperative Extension, Orange County; Akif Eskalen, UC Davis Plant Pathology; Stacy Hishinuma, USDA Forest Service; Shannon Lynch, State Univ.
In a NAISMA blog post, Dr. Beatriz Nobua-Behrmann, Urban Forestry and Natural Resources Advisor with UC Cooperative Extension, explains how to identify infestations by invasive shothole borers and how you can protect your trees from this pest and its pathogenic fungi.
An all-star lineup of tree pest experts from UC Cooperative Extension and other organizations will speak about Pests & Diseases of Southern California Trees at the Winter 2022 Street Tree Seminar. Offered online through Zoom, the seminar takes place Thursday, February 24 from 8:30 am to 3:30 pm.
