California is home to over 30 introduced psyllid species, far more than any other state. Some are minor pests of ornamental trees, while others, such as the Asian Citrus Psyllid, are important economic pests. The primary hosts for all psyllids that have been introduced into the state are listed here. Many of these psyllids are still established in California, but for some species no recent records have been documented.
