Ebeling, W. 1932 Experiments with oil sprays used in the control of the California red scale, Chrysomphalus aurantii (Mask.) (Homoptera: Coccidae) on lemons.. Journal of Economic Entomology 25: 1007-1012.

Notes: Data are presented which indicate that the effectiveness of oil sprays is proportional to the heaviness of the oil and the percentage of oil used in the spray, and inversely proportional to the amount of spreader used in the spray.
