中文摘要：柑橘全爪螨 Panonychus citri (McGregor)是柑橘上的重要有害生物，控制上目前仍以化学防治为主，捕食螨也在一些果园采用。安全性较高
的农药正不断推广应用，一些生物源农药也已大面积使用。不过这些农药对柑橘全爪螨及其它柑橘害虫的田间控制效果如何，是否影响到商品
捕食螨和果园自然天敌的种群维持与发展及其对柑橘害虫的持续控制，仍需较多而深入地检测和评估。2011年4—2012年1月，在广东省封开县
，选择了3个不同害虫防治措施（以阿维菌素为主，巴氏新小绥螨Neoseiulus barkeri＋矿物油乳剂为主，胡瓜新小绥螨N. cucumeris＋苦参
碱为主）的果园，调查比较了不同害虫防治措施对柑橘全爪螨的防治效果及对柑橘园中天敌类群的影响。试验结果显示，以巴氏新小绥螨＋矿
物油乳剂为主和以胡瓜新小绥螨＋苦参碱为主的果园内自然天敌的丰富度高于以阿维菌素为主的果园，其群落结构也有所不同，它们对柑橘全
爪螨和其它柑橘害虫的田间持续控制效果也比以阿维菌素为主的措施更好。
英文摘要：Panonychus citri (McGregor) is a major pest of citrus that is still controlled predominantly by chemical pesticides,
although predatory mites are used in some orchards. Although safer chemical pesticides are now used in many citrus orchards
there is a need to determine the effects of these pesticides on predatory mites and other natural enemies of P. citri. This
experiment was carried out in citrus orchards in Fengkai County, Guangdong Province from April 2011 to January 2012. Three
treatments were investigated: (1) Abamectin used as the main control agent; (2) Matrine used as the main control agent plus
the predatory mite Neoseiulus cucumeris; (3) Mineral oil used as the main control agent plus the mite N. barkeri. The
results show that the richness of natural enemy groups in citrus orchards controlled by Matrine + N. cucumeris and by
Mineral oil + N. barkeri was higher than that in citrus orchards in which control was achieved predominantly with abamectin.
The community structures of natural enemy groups differed under the different treatments. The sustained control effects of
Matrine + N. cucumeris and Mineral oil + N. barkeri were better than those achieved by predominantly using abamectin.
