The southern coast of the Caspian sea is an increasingly urgent problem, because of pesticide application and different type of cancers are increasing. The response of the citrus red mite, Panonychus citri to different doses of mineral oil and determination of LC50 and LC90 using bio-assay technique was tested. The treatment applied in two different techniques including: slide dip method and using backpack sprayer. Laboratory evaluation indicated that in very low concentration of narrow-range mineral spray oil the mortality was very high, using slide dip method. The LC50 and LC90 were calculated 0.44 and 0.85%, respectively, using backpack sprayer. The dilute application of 0.85% mineral oil compared with conventional control and just control in the citrus orchard. There were no significant differences between two treatments of mineral oil and conventional control. Therefore, according to the two years results the concentration of 0.85% mineral oil in water should control the citrus red mite. Results are discussed in terms of a sustainable, integrated pest management system.
