【摘要】 梨小食心虫为世界性果树害虫，主要为害仁果类（如苹果、梨等）、核果类果树（如桃等）的新梢和果实。该虫虫体小、钻蛀性为害，隐蔽性强，发生代数多、世代重叠严重，生产上防治困难。而过度化学防治会导致“三R”问题严重，梨小食心虫发生为害已成为限制果树高质量绿色发展的主要因素之一。对梨小食心虫的生物学特性、综合防控措施（包括农业和物理防治，化学防治，生物防治、综合防治等）进行综述，以期为梨小食心虫的综合防控提供参考。更多还原

【Abstract】 Grapholita molesta Busck is a global fruit tree pest that mainly damages the new shoots and fruits of fruit trees such as apple and pear,as well as stone fruit trees such as peach. Due to its small size,more generations each year,and overlapping generations,it is difficult to be controlled in production. However,excessive chemical control can lead to resistance,resurgence and residue. It has become one of the main factors limiting the high-quality and green development of fruit trees. The biological characteristics and comprehensive pre-vention and control measures are summarized including agricultural and physical control,chemical control,biological control,and comprehensive control in order to provide reference for the integrated control ofthis pest.更多还原
