These studies were carried out to investigate the amounts and preferences of Oligota kashmirica benefica to 3 species of phytophagous mites and cannibalism. The number of mites consumed by an adult beetles tended to increase as prey density and temperature o up. In the constant temperature of 25¡É , average number of consumed adult mite by an adult of O. kashmirica benefica to Panonychus citiri, Tetranychus urticae and T. kanzawai were 21.9, 13.5 and 14.1 for a day, respectively. The number of mites consumed by larva of O. kashmirica benefica tended to increase as the larva grow up. First, 2nd and 3rd larva of the beetle consumed 2.8,11.2 and 25.4 adult of citrus red mite for a day, respectively. Total number of mites consumed during larval stage to P. urticae and T. kanzawai were 77.7, 61.3 and 73.0, respectively.
