November 2010. A whitefly found on the undersides of soursop (Annonasquamosa) leaves. The adult is small (0.74 mm body length); wings with two dark bands. Immatures exude pale blue-green opalescent glassy rods. The host was sweetsop, Annona squamosa.
The same member sent another email later, saying that specimens were sent to Greg Evans, USDA-APHIS, and they were identified as Dialeuropora decempuncta. This species has been recorded in a report on a Pacific Islands whitefly survey done by Paul De Barro and Wilco Liebregts in 1996/7 at http://tinyurl.com/DeBarroReport. This report lists D. decemuncta among several new whiteflies collected on Guam.
