Abstract
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 beetle tended to increase as prey density and temperature go up. In the constant temperature of 25$^{\circ}C$, average number of consumed adult mites by an adult of O. kashmirica benefica to Panonychus citri, 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 (P. citri) for a day, respectively. Total number of mites consumed during larval stage (5 days, 25$^{\circ}C$) to P. citri, T. urticae and T. kanzawai were 77.7, 61.3 and 73.0, respectively. The larva and adult beetle did not prefer specific species in the P. citri, T. urticae and T. kanzawai, and when there was no diet, few incidents of cannibalism between different developmental stage were observed.
