Phytoseiid mites are rich in our country and the work of collecting resouce begun at the end of 70’s in twenty century. Over 260 phytoseiid mites species had been identified in crops of different area , including about 20 very useful species. At the optimun temperature 25～ 30 ℃, the developmental time of phytoseiid mites from egg to adult is about 6～7 days and their longevity are 30～50 days. The response of phytoseiid mites to lots of injurious mites belongs to Holling’s Ⅱequation. Many phytoseiid mites are hydrotropic species of like humidity and high relative humidity has beneficial effect on egg hatching and mite survival. When high temperature in summer or low temperature in winter , phytoseiid mites could passed the adverse circumstances by oversummer or overwinter for a short time. Phytoseiid mites need mating to produce eggs. No matting or lack matting times lead
