Abstract
Efficiency of Misrona Super oil to various life stages of_the California red scale, Aonidiella aurantii and the citrus white fly, Dialeurocies citri infesting orange trees by ground spray motor (48 I. M.S. oil/fed.) and aerial spray by helicopter (10 I.M.S. oil/fed.) in Sharkiya Governorate was investigated. Both methods gave satisfactory results and no phytotoxicity was observed after winter application with a superior efficacy for helicopter. Insects existing on the low and high levels of orange trees were the most responsive to the miscible oil activity especially in aerial application. Also, the immature stages of both pests were most sensitive to the m.s. oil efficacy than the pupal and adult stages. Therefore, it seems that helicopter might be introduced as a useful technique for controlling scale insects and white flies by using miscible oil especially in case of large areas of citrus trees. This method saves great amount of chemicals, water, time, cost and minimizes the environmental pollution.
