Abstract

The effect of three mineral oils; Star oil, Shokrona oil and Shokro­na Super, as well as Vertimec (abamectin 1.8% E.C., natural product produced by the soil microorganism, Streptomyces avermitis) and Di-thane M-45, against the citrus rust mite Phyllocoptruta oleivora and the citrus brown mite, Eutetranychus orientalis was evaluated. Results indicated that Dithane M-45 was the most effective com­pound in reducing citrus rust mite population and produced the least percentage of russetted fruits. Vertimec came next, followed by Shokro­na Super, Star oil then Shokrona oil. Vertimec was the most toxic com­pound against the citrus brown mite followed by Shokrona Super, Star oil then Shokrona oil.
