The woolly whitefly, Aleurothrixus floccosus Mask., first discovered in residential San Diego during November 1966 surveys for the citrus whitefly, has been of deep concern to the citrus industry , the University of California, and various agricultural agencies. In 1968, a study by Harold Lewis for the California-Arizona Citrus League estimated potential losses to California citrus of $10 per acre for either whitefly or a 17 percent average increase in total pest control costs statewide.
