摘要： 为明确有机生产方式下桃园害虫和天敌数量变化，2004年在北京平谷区前芮营村有机桃园用性诱剂法和捕虫网法分别调查了3种主要害虫（梨小食心虫、 苹小卷叶蛾和桃潜叶蛾）和4种主要天敌（龟纹瓢虫、异色瓢虫、七星瓢虫、小花蝽和草蛉）的发生规律。结果表明：3种害虫世代较明显，发生高峰集中；天敌数量逐渐积累，数量增加明显。

Abstract: In this experiment, author investigated the dynamic of the three main pests (Grapholitha molesta Busck, Adoxophyes orana Fischer von Roslerstamm and Lyonetia clerkella Linnaeus)and the four main natural enemies(Propylaea japonica(Thunbery), armoia(Leis)axyxidis, Coccinella septempunctta, Orius minutus and Chrysopidae ) with the synthetic sex pheromone lures and the clap nets for understand dynamic of pests and natural enemies under organic management. The results shown that the generations of the three pests are distinctness, the peak of appear convergent; the number of the natural enemies accumulate gradually, the developing regulation is clear.
