Helmy, E.I., Hindy, M.A., Hassan, N.A., & El-Immry, S.M. 1997 Comparison between aerial and ground spraying against the California red scale, Aonidiella aurantii (Mask.) and Dialeurodes citri (Ashmead) on citrus trees.. Egyptian Journal of Agricultural Research 75: 601-609.

Notes: The efficiency of Misrona Super Oil to control various life stages of Aonidiella aurantii and Dialeurodes citri, infesting sweet oranges in Egypt, was investigated during 1994. Two spraying methods were used, a conventional ground spray and a low volume aerial spray by helicopter. Both methods resulted in sufficient insect control, but aerial spraying was more efficient. No phytotoxicity was observed. Immature stages of both pests were more susceptible than pupal and adult stages.
