摘　　要：梨小食心虫产卵选择行为反映其与寄主植物之间的相互关系,是在长期协同进化过程中形成的。为繁衍后代,梨小食心虫必须选择合适的寄主与位置进行产卵,以利于其后续各虫态生长发育,完成整个生活史,提高种群数量,扩大危害。从空间环境因素(方位和层次)、梨小食心虫感官因素(嗅觉、视觉和触觉)以及寄主果树因素(不同果树和相同果树不同品种)3个方面对梨小食心虫产卵选择行为及其机制进行了综述,可为田间虫情调查、杀卵剂定向喷施,以及果树抗虫品种选育、栽培品种选择及搭配等提供理论指导。The oviposition preference can reflect the relationship between Grapholitha molesta（Busck）and host plant, which forms in the process of long- term cooperative coevolution. G. molesta（Busck）must choose the appropriate host plant and location to oviposit for reproduction, and it is favourable to the growth and development of the subsequent stage, complete the entire life cycle, improve the population, and expand the harm. This paper reviewed the oviposition preference behavior and mechanism of G. molesta（Busck）from the space environment factors（azimuth and layer）, sensory of G. molesta（Busck）factors（smell, sight, touch）and host plant factors（different host plant and different varieties of same host plant）. It could provide theoretical guidance at the insect survey and ovicide directional spraying in field, insect- resistant varieties breeding, fruit cultivars selecting and collocating and so on.
