摘　　要：枣粘虫（Ancylis sativa）是枣树主要的食叶和蛀果害虫,为了控制其危害,2004年在太谷地区对4种不同处理枣林的枣粘虫天敌发生与态势进行了系统的调查研究,结果表明种草综合防治枣林枣粘虫天敌昆虫的物种数比种草常规防治枣林、未种草综合防治枣林和未种草常规防治枣林分别增加37.2%、84.4%和118.5不%,个体数分别增加39.2%、91.0%和187.4%,枣粘虫幼虫和蛹的寄生率分别增加46.94%和31.27%、35.21%和21.99%、116.42%和60.33%;综合防治枣林区草蛉类和寄生性天敌类的丰盛度明显大于（P〈0.05）化学防治的枣林,而瓢虫类与蜘蛛类则明显小于（P〈0.05）化学防治的枣林,食虫蝽类与其它捕食性天敌则是种草枣林区大于未种草枣林区;枣林种草后天敌的恢复与重建速率提高了50%-81%;种草枣林多样性的标准误明显减小,相关性测定表明枣粘虫天敌功能团与物种的优势度、多样性、均匀度的变化趋势较为一致,均极显著（P〈0.01）相关。To understand the ecological impact both intercropped herbages and management methods in jujube plantation on natural enemies and Ancylis sativa,during March 10 to September 30 in 2004 a systematic survey was conducted under four treatments toward the jujube trees that were all in 10-years old and in full fruit production in a jujube plantation that is located 2.5 km west of Taigu（111°32＇E,37°26＇N,781.9 m elevation）in Shanxi Province,China.Among the four different treatments,two of them applied intercropped herbage treatment（Lotus comiculotus）,and other two without herbage treatment.In each treatment,five trees chosen by the chessboard sampling method were used to monitor and record the population dynamics of natural predators in every 10 days.Each treatment was performed in triplicate.The natural enemies were distinguished based on their trophic relationships and taxonomy.Abundance and dominance of species,diversity indices of community were used to analyze and compare the successions of natural enemies in the four different treatments. Compared with conventional management jujube field intercropped with herbage,integrated pest management jujube field without herbage,and conventional management jujube field without herbage,we found that the species of natural enemies of Ancylis sativa in the jujube plantations intercropped with herbage and applied IPM increased by 37.2%,84.4% and 118.5%,respectively;and the individual number of natural enemies of Ancylis sativa by 39.2%,91.0% and 187.4%,respectively.Parasitic ratio of the larvae and pupa of Ancylis sativa increased by 46.94% and 31.27%,35.21% and 21.99%,and 116.42% and 60.33% respectively.Abundances of lacewings and parasite natural enemies of Ancylis sativa in the jujube plantations under the integrated pest management were significantly larger than the chemically controlled jujube plantations（P〈0.05）.On the contrary,the abundances of spiders and ladybirds were significantly smaller than their respective counterparts（P〈0.05）.Also in t
