The population of Tetranychus urticae was also less than 1 mite per eggplant leaf from September 1 to October 22 after three times releases of 10 P. persimilis in autumn season experiment. In Phytoseiulus persimilis released plot, the percentage of leaves with T. urticae adults and nymphs were 8.6~13.3% and 5% or less in spring and autumn season experiment.
