摘　　要：【目的】梨小食心虫、桃小食心虫和苹果蠹蛾是新疆果树的主要害虫。研究利用性诱剂监测这3种食心害虫在南北疆不同果园的消长动态,分析其世代发生规律,为梨小食心虫、桃小食心虫和苹果蠹蛾的害虫防治工作提供依据。【方法】利用性诱剂对梨小食心虫、桃小食心虫和苹果蠹蛾开展检测预报。【结果】2009年,梨小食心虫和桃小食心虫年在轮台地区和石河子地区一年分别发生5代、4代。苹果蠹蛾在轮台地区一年发生4代,在石河子地区有少量的出现。在不同地区的不同果园内,诱集到的梨小食心虫、桃小食心虫和苹果蠹蛾是不同的。【结论】果树混栽的果园内,梨小食心虫、桃小食心虫和苹果蠹蛾的发生程度较严重。梨小食心虫、桃小食心虫、苹果蠹蛾存在着世代重叠现象,化学防治的重点应放在第一代幼虫上。【Objective】Oriental fruit moth（Grapholitha molesta Busck）,peach fruit borer（Carposina niponensis Walsingham） and codling mothcodlingmoth（Cydia pomonella（L.）） are the main pests on Xinjiang fruit trees.The purpose of this research is to detect and prevent them better by monitoring the growth and decline trends of the three borer pests in Xinjiang in the different orchards by using pheromone trap.The paper analyzed their generation occurrence regularity and provided the basis of preventing them.【Method】The pheromone trap was used to detect and prevent the Grapholitha molesta Busck,Carposina niponensis Walsingham and Cydia pomonella（L.）.【Result】In 2009,5 generations of Grapholitha molesta Busck and 4 generations of Carposina niponensis Walsingham appeared in Shihezi and Luntai districts.4 generations of Cydia pomonella（L.） appearedmin Luntai district,but only small number appeared in Shihezi district.What were trapped in the different orchards in different regions,were different.【Conclusion】Grapholitha molesta Busck,Carposina niponensis Walsingham and Cydia pomonella（L.）.were serious occurrence in the orchards which are mixed with other fruit trees.The phenomena that different generations of Grapholitha molesta Busck,Carposina niponensis Walsingham and Cydia pomonella（L.）.overlapped existed,it is very important for killing the first generation.
