Subject: Detection of the armored scale Duplachionaspis divergens in Florida, U.S.A.
Date posted: January 10, 2002
Source: USDA-ARS and FL DPI
Specimens of this Indian species of scale were collected on "grass" near Orlando, FL in November, 2001. This constitutes the first occurrence of D. divergens in North America; the only other incidence of this scale in the New World is one collection from Columbia. In India, the host range of D. divergens encompasses mainly members of the family Poaceae, and is known as a minor pest of young sugar cane plants, as well as lemongrass (Cymbopogon spp.). As a possible pathway for this species, lemongrass is imported from regions where D. divergens is found. It is unclear whether this organism presents a significant pest threat in North America.
