U.S. quarantine notes

This species was intercepted 7 times at U. S. ports-of-entry between 1995 and 2012, with specimens originating from Guam, Hong Kong, Indonesia, Malaysia, The Philippines, and Taiwan. We also have examined specimens taken in quarantine from Guam (Areca); Indonesia (Areca); Malaysia (Cordyline, Nomaphila); New Guinea (Begonia); Palau Islands (Areca); Taiwan (palm). ScaleNet includes hosts in more than 25 plant families from the Australasian and Oriental zoogeographic regions. No other species of Icerya have been taken in quarantine at U. S. ports-of-entry other than I. aegyptiaca (Douglas), I. pulchra (Leonardi), I. purchasi (Maskell), I. samaraia and I. seychellarum (Westwood).
