摘　　要：苹果蠹蛾是苹果、梨等仁果类果树上的重要害虫,也是重要的入侵害虫。其具有寄主广泛、适生性强、蛀果为害等特点,一旦侵入很难彻底根除。老熟幼虫脱果后寻找隐蔽场所滞育的习性是其适应不利环境和维持种群繁衍的重要生存策略。本文就苹果蠹蛾幼虫滞育的诱导和终止因素、滞育场所的选取及聚集习性、滞育幼虫对环境的适应能力及内在生理生化特性以及针对滞育幼虫的防治技术等研究进行了综述,为探明苹果蠹蛾的灾变机理、预测预报和防治提供依据。The codling moth,Cydia pomonella（ L.）,is a notorious invasive fruit pest of apple,pear and other pome fruits. Eradication of this invasive pest is difficult,due to its extensive host range,high habitat suitability and larval feeding inside fruits. The mature larva leaves damaged fruit for shelter where pupation or diapause happens. The diapausing larva can survive under adverse natural conditions and diapause is also the most important survival strategy for the population. The present review summarizes the factors of inducing and terminating diapause,the selection of diapause sites,aggregation behavior,environmental adaptability and physiological and biochemical characteristics of diapausing larvae. Research on diapause propensity in C. pomonella can provide a reference basis for prediction and control of the pest.
