U.S. quarantine notes

This species has never been taken in quarantine, but because it is a serious pest in Europe and has been expanding its distribution, we decided to include it. ScaleNet records the species from Pinus maritima and P. pinaster from the Palaearctic region. No other species of Matsucoccus other than M. matsumurae (Kuwana) have been taken in quarantine at U.S. ports-of-entry.
