摘　　要：【目的】摸清新疆阿克苏地区苹果园金纹细蛾的发生规律,为该虫的综合治理提供科学依据。【方法】选择不同树龄、不同品种、不同间作方式的苹果园,利用性诱剂诱捕法和田间调查法,研究金纹细蛾的发生危害规律。【结果】金纹细蛾在阿克苏地区1年发生6代,第一代成虫发生期为5月上旬至6月上旬,第二代6月中旬至7月中旬,第三代7月中旬至8月上旬,第四代8月中旬至8月下旬,第五代9月上旬至10月。不同类型的果园中金纹细蛾危害程度和发生量不同,其中20年树龄果园>5年树龄果园、清耕果园>间作1年生绿肥作物果园>间作多年生绿肥作物果园、红色之爱果园>红富士果园。【结论】金纹细蛾以蛹在危害叶片虫斑内化蛹越冬,在阿克苏地区1年发生6代,其中7—8月危害较严重,老龄果园、清耕果园发生重,对不同品种的嗜好性也有差异。【Objective】Lithocolletis ringoniella is a kind of leaf pest of fruit trees that mainly harms apple trees and seriously reduces fruit production.With the development of the characteristic fruit tree industry in Xinjiang,L.ringoniella has occurred in the Aksu area in recent years.The study aimed to find out the occurrence regularity of L.ringoniella in Apple orchards in southern Xinjiang,and to provide scientific basis for integrated management of the pest.【Methods】In this paper,the occurrence and damage rule of the L.ringoniella was studied by the methods of sexing attraction trapping and field investigation in apple orchards with different ages,varieties and intercropping patterns.In each treatment orchard,three sets of traps were placed respectively.They were hung with wire on the trunk of a ventilated area on the dark side of the fruit trees at a height of 1.5 meters or in the middle and lower part of the tree crown.Each set of traps was hung with one sex attractant and a sticky trap was installed.From March 12 to September 28,the number of L.ringoniella on the sticky trap was surveyed once a week,and the sticky trap was replaced.The sex attractant was replaced every three weeks.From May 20 to September 28,5 trees were selected from each orchard for marking,and 1 branch was identified from the east,south,west,north,and middle of each tree.20 leaves were investigated on each branch.100 leaves were investigated for each tree,and the number of damaged leaves was classified and counted.【Results】The results showed that the L.ringoniella occurred 6 generations in a year in southern Xinjiang.The overwintering adults began to emerge when the average temperature of 7 consecutive days in spring was over 7.1℃.There was no obvious discontinuity between the generations of L.ringoniella adults in each treatment,and the number of the first and second generations was small and the duration was long.The number of L.ringoniella adults in the third and fourth generations increased significantly,and the duration was
