U.S. quarantine notes

This species was intercepted 2 times at U. S. ports-of-entry between 1995 and 2012, with specimens originating from Mexico. We also have examined specimens taken in quarantine from Colombia (Annona); Costa Rica (palm); Guatemala (Chamaedorea); Panama (Musa); St. Croix (Meliococcus). ScaleNet includes hosts in 7 plant families from the Nearctic and Neotropical zoogeographic regions. Four species of Crypticerya other than C. rosae and C. genistae (Hempel) have been intercepted at a U. S. port-of-entry including: C. littoralis (Cockerell) (Mexico, on Carica, Chamaedorea, and Persea; Guatemala, on Chamaedorea); C. montserratensis Riley & Howard (Colombia, on orchid; Dominican Republic, on Annona; Guatemala and Mexico, on Chamaedorea); C. similis Morrison (El Salvador, on Laelia); and C. zeteki (Cockerell) (El Salvador, on orchid).
