AB  - The polyphagous shot hole borer (PSHB) is an invasive ambrosia beetle that forms 
      a symbiosis with a new, as-yet-undescribed Fusarium sp., together causing 
      Fusarium dieback on avocado and other host plants in California and Israel. In 
      California, PSHB was first reported on black locust in 2003 but there were no 
      records of fungal damage until 2012, when a Fusarium sp. was recovered from the 
      tissues of several backyard avocado trees infested with PSHB in Los Angeles 
      County. The aim of this study was to determine the plant host range of the 
      beetle-fungus complex in two heavily infested botanical gardens in Los Angeles 
      County. Of the 335 tree species observed, 207 (62%), representing 58 plant 
      families, showed signs and symptoms consistent with attack by PSHB. The Fusarium 
      sp. was recovered from 54% of the plant species attacked by PSHB, indicated by 
      the presence of the Fusarium sp. at least at the site of the entry hole. Trees 
      attacked by PSHB included 11 species of California natives, 13 agriculturally 
      important species, and many common street trees. Survey results also revealed 19 
      tree species that function as reproductive hosts for PSHB. Additionally, 
      approximately a quarter of all tree individuals planted along the streets of 
      southern California belong to a species classified as a reproductive host. These 
      data suggest the beetle-disease complex potentially may establish in a variety of 
      plant communities locally and worldwide.
