摘　　要：为了研究香梨优斑螟在红枣上的为害情况,随机选取了新疆阿拉尔垦区4~10a树龄的17个枣园,开展香梨优斑螟在树体上的为害痕迹调查。结果表明:调查枣园都有受到香梨优斑螟为害现象,枣园最低受害率为4.00%,最高为50.40%,其中受害率低于10%的枣园占总调查枣园的41.2%,受害率50%以上的仅为5.9%,总体上发生较轻。通过受害率与树龄之间的相关性分析,没有发现树体受害痕迹随着树龄的增加而上升(R^2=0.1969),因此推测香梨优斑螟在红枣上为害历史较短,并可能有为害加重的趋势。In order to study the injury situation of Euzophera pyriella on the red jujube,we randomly selected the 17 jujube gardens of 4-10 years old in the Alar area of Xinjiang,and carried out the investigation on the damage trace of Euzophera pyriella on the tree body.The results showed that the investigation of jujube garden has been affected by Euzophera pyriella.The jujube suffer rate was 4.00%-50.40%,the victimization rates less than 10%of jujube accounted for 41.20%of total survey jujube gardens,more than 50.00%of victimization rate was only 5.90%,generally lighter.Through correlation analysis between the age and victimization rates,found no traces tree body suffer and rise with the increase of tree age(R 2=0.196 9),suggesting that the pests harm on jujube history is shorter,and may have the tendency of the damage.
