Prunus sp. are P. acericola and P. psidii reported
as occurring on the same host. Pulvinaria ur-
bicola and P. psidii are frequently reported from
the same hosts, but they usually occupy different
habitats on the plant. Pulvinaria psidii occurs on
leaves and small young stems, whereas P. ur-
bicola usually occurs on the stems at ground
level. The combination of stout, fringed
marginal setae, multilocular pores with 10
loculi, numerous dorsal tubular ducts, and usu-
ally a sclerotized plate enclosing the spiracles will
differentiate P. psidii from other members of the
genus in Florida.
