摘要： 本文报道1984-1986年对枣尺蠖和枣壁虱防治指标的研究及应用结果。初步提出，枣尺蠖的防治指标为百股平均幼虫7.5头，枣壁虱的防治指标为叶平均虫量0.5头。研究及生产示范试验证明，枣树开花前（5月中旬）为最佳防治时期；采用主治和兼治相结合，治虫与施肥相结合，辅以夏剪管理的综合防治措施，只在花前喷药防治一次，即能很好地控制枣树的5种主要害虫。

Abstract: Results of the study and application of the index for controlling S.jujuba and E.annaltus were reported.The study was Carried out during 1984-1986 in Henan province.The indexes of 7.5 larvae per hundred jujube thigh for S.jujuba and 0.5 insect per leaf E.annaltus were suggested.The study and and demonstration experiment indicated that the optimum time for control was before flowering of Chinese jujube(mid May).Five main insect pests could be well controlled by integrated management combining pestcide spraying once before flowering with fertilizer application and summer pruning.
