Larry Arrington, Dean Introduction Red wax scale, Ceroplastes rubens Maskell, was first found in Florida at an Orange County nursery on the foliage and stem of greenhouse-grown Aglaonema pictum var. tricolor and A. oblongifolium 'Curtisii' in November 1955. This collection was a new Florida and continental United States record of an introduced plant pest. Introduced foliage plants apparently were responsible for the establishment of this insect in Florida.
