梨小食心虫（Grapholitha molesta Busck）是鳞翅目（Lepidoptera）卷蛾科（Tortricidae）一种具有蛀果习性的世界性害虫，主要危害蔷薇科植物并造成严重经济损失。同其他植食性昆虫一样，梨小食心虫对寄主植物的准确定位关系到觅食、求偶、交配和后代存活，乃至整个种群繁衍等生命活动。基于“梨小食心虫—蔷薇科植物”之间的相互关系，综述了梨小食心虫寄主定位行为的研究现状，并分析影响该行为过程的重要化学、物理和生理等因素，探讨昆虫行为调控技术在梨小食心虫等蛀果类害虫综合防控中的应用前景，为今后研究该类害虫对不同寄主植物的潜在危害及防控奠定理论基础。

The oriental fruit moth ( OFM), Grapholitha molesta Busck, is a worldwide fruit pest of Tortricidae,Lepidoptera.It prefers to infect various fruit trees of Rosaceae and causes serious economic losses.Like other phytophagous insects,pinpoint host-location is closely related to feeding, courtship,mating and offspring survival of OFM,even related to reproduction of the whole population.In the paper,based on the interaction between OFM and host-plant(Rosaceae),research status of host location behavior of OFM is reviewed.Through analyzing the effects of chemical,physical and physiological factors on the behavior strategy,the application prospect of behavior regulation technology is explored for improving prevention and control of OFM in different host plants.
