Sprays of 1% of a special light oil plus parathion or malathion were compared with 1.8% light medium oil alone and with malathion for control of black scale, Saissetia oleae, on-oranges in California. One % of light oil with 0.12 or 0.15 lb. of parathion or 0.25 lb. of malathion was as good as the 1.8% of light medium alone or with malathion on black scale, but less effective on the citrus red mite, Metatetranychus citri. Control of light infestations of California red scale, Aonidiella aurantii was satisfactory. The light oil combination had little effect on the appearance of the fruit and did not accentuate water rot in navel oranges.
