Today, we venture into the critical realm of invasive pests, zeroing in on the invasive shot hole borer (ISHB), a formidable newcomer from southern Asia threatening California's trees. We navigate through the fascinating biology of the ISHB, discussing its rapid spread and dire consequences for urban and native forests alike, not only threatening California’s tree canopy, but over 65 species of trees throughout the country. 

We are joined by Dr. Beatriz Nobua-Behrmann from the University of California Cooperative Extension, who sheds light on the pest's impact to a wide variety of ornamental trees, including a very important agricultural crop, avocado trees.

We will emphasize the importance of monitoring and early detection of the Invasive Shot Hole Borer, with Dr. Nobua-Behrmann outlining diagnostic signs and mitigation strategies. We highlight integrated pest management techniques and the potential of biological controls, such as the introduction of parasitoid wasps.
