摘要(Abstract)：

【目的】明确郑州地区桃园梨小食心虫发生规律、危害特点及适宜应用的最佳诱捕器类型,为梨小食心虫科学防治提供理论依据。【方法】以国家果树种质郑州桃圃为试验园,利用梨小食心虫性信息素诱芯制作的不同诱捕器诱捕梨小食心虫成虫,结合田间折梢率和蛀果率调查及气象资料记录,进行数据分析。【结果】梨小食心虫在郑州地区包括越冬代在内一年发生6代,2、3世代种群数量最大,越冬代与第1世代间界限明显,后面4个世代存在明显世代交替;梨小食心虫以幼虫危害新梢和果实,最大折梢率和蛀果率发生期分别与梨小食心虫幼虫的大量发生期相对应;郑州桃园梨小对自动补水型诱捕器选择性更强,相同条件下,用该诱捕器诱捕到的梨小成虫较多。【结论】针对梨小食心虫的发生规律和危害特点,适合郑州桃园梨小食心虫诱捕的诱捕器为自动补水型。
