摘　　要：通过对昆明地区云南樟和山玉兰上的黄圆蹄盾蚧进行系统调查和室内饲养,共收集到捕食性天敌昆虫6种,即日本方头甲、二双斑唇瓢虫、红点唇瓢虫、七星瓢虫、异色瓢虫、日本通草蛉。其中日本方头甲是主要捕食性天敌。寄生性天敌5种,即双带巨角跳小蜂、双带花角蚜小蜂、长缨恩蚜小蜂、盾蚧汤氏跳小蜂和金黄蚜小蜂。双带巨角跳小蜂是主要寄生性天敌,在昆明一年发生4代,4月中旬开始羽化,7月中旬至9月中旬是双带巨角跳小蜂羽化盛期。双带巨角跳小蜂对黄圆蹄盾蚧的种群数量有一定的控制作用。For effective control of the scale make use of the natural enemies. Predatory insects, the most important measurement is to protect and and parasitic natural enemies of Aonidiella citrina were collected after systemic investigation in the field and rearing in the laboratory in Kunming. The predatory natural enemies were identified as six species, Cybocephalus nipponicus, Chilocorus bijugus, Chilocorus kuwanae , Coccinella septempunctata , Harmonia axyridis and Chrysoperla nipponensis . Among them, C. nipponicus was the most important predatory enemy. There were five species of parasitic natural enemies, Comperiella bifasciata , Azotus perspeciosus , Encarsia citrina , Thomsonisca amathus and Aphytis chrysomphali. C. bifasciata was the most important parasitic enemy. All the natural enemies had a certain control effect on the population of A. citrina in the field. C. bifasciata had four generations a year. The adult emergence started in the middle of April after the winter, and emergence peak was from the middle of July to the middle of September.
