摘要: 为了解“玉露香梨”采前落果特点及成因，本研究分别对迷向区、生草区、清耕区3个区的落果特点进行了分析.结果表明，“玉露香梨”采前落果主要由梨小食心虫(Grapholitha molesta)、黄粉蚜(Aphanostigma jakusuiense)、自然落果、鸟啄4种情况造成； 3个区域中以梨小食心虫造成落果占比最高，为63.31%，其次为自然落果，占比34.43%，两者均显著高于黄粉蚜和鸟啄造成的落果；梨小食心虫是造成落果的主要原因并且边缘位置发生程度高于中心位置.本研究最后提出防止香梨落果的具体防治措施，可为“玉露香梨”虫害防治提供理论支撑.

Abstract: In order to understand the characteristics and causes of 'Yulu pear' fruit drop before harvest，the studies were carried out in three areas of sex pheromone disorientation area，grass growing area and clear tillage area. The results showed that the pre-harvest fruit drop in 'Yulu pear' was mainly caused by Grapholita molesta，Aphanostigma jakusuiense，natural fruit drop and bird pecking. In the three areas，the fruit drop caused by G. molesta was the highest at 63.31%，followed by natural fruit drop at 34.43%，both of which were significantly higher than those caused by A. jakusuiense and bird pecking. G. molesta was the main cause of fruit drop and the degree of occurrence in the edge position was higher than that at the center. This study proposed specific control measures to prevent the pear fruit drop，which could provide theoretical support for the pest control of 'Yulu pear'.
