Invasive Shot Hole Borer or ISHB, is an exotic ambrosia beetle that was first detected in 2003 in southern California and is responsible for attacking a large number of tree species by transmitting fungus that can kill a tree in 2-3 years. Adult beetles are either black or brown in color, whereas larvae are white and grub-like. The term “ambrosia” refers to two or more fungi species that are carried by the female and inserted into tree when she mines galleries into the sapwood. The fungus grows in the galleries, where developing adults and larvae feed on it. The presence of both the galleries and the fungi increases tree stress and can lead to tree mortality.
