中文摘要： 通过对山西临汾桃园苹小卷叶蛾（以下简称苹小）Adoxophyes orana (Fischer von Rosslerstamm)、梨小食心虫（以下简称梨小）Grapholita molesta (Busck)的调查，明确山西临汾桃园苹小和梨小的发生规律，苹小和梨小均是临汾桃园的重要害虫，梨小和苹小不仅种群数量在年度间波动较大，而且种群动态的趋势在年度间也不一致。首次指明梨小的化蛹场所，梨小在树上寻找多种类型的隐蔽处化蛹。苹小对糖醋液的趋性显著强于对性诱剂的趋性，梨小对性诱剂的趋性显著强于对糖醋液的趋性，根据苹小梨小对糖醋液和性诱剂的趋性特点和他们各虫态的发育历期，对桃园苹小和梨小的防治提出较为合理的思路。
英文摘要： The summer fruit tortrix moth Adoxophyes orana (Fischer von Rosslerstamm), and the Oriental fruit moth, Grapholita molesta (Busck), in peach orchard were investigated in Linfen City, Shanxi Province during peach growing season in 2006 and 2007 The results showed that both the summer fruit tortrix moth and oriental fruit moth were main pests in peach orchard. But sizes of the populations in these two pests changed between 2006 and 2007 The Oriental fruit moths preferred to stay at shelter of peach tree when they pupated, and they could be induced significantly more numbers by the sugarvinegar liquid versus the sex pheromone. but the Oriental fruit moth was reverse to the Oriental fruit moths. According to the development period and trend toward the sugar-vinegar liquid or the sex pheromone in these two moths, we also discussed the methods of pest control.
