摘　　要：通过引移释放尼氏钝绥螨 ,保护利用桔园天敌 ,生物防治与化学防治的协调管理等措施的应用 ,对柑桔叶螨防治的年均施药次数从 6.2 3次减少到 1.94次 ,防治用工减少 5 4.0 7% ,防治费用减少 77.78% ,柑桔产量提高 15 68.4kg/hm2 ,新增投入产出比达1∶10 .97。The study on introducing and releasing the Predatory mite (Amblyseius nicholsi Ehara),protecting and using the nature enemies of the pest, managing the biological insect controlling and chemical controlling congruously and so on were carried out. The degree of using pesticides had dropped from 6.23 times to 1.94 times, the labor cost of controlling the citrus mite had reduced 54.07%, all the cost of controlling the citrus mite had reduced 77.78%, the yield had increased 1?568.4?kg/hm 2,the new proportion of input-output was 1∶10.97.
