摘要(Abstract)：

核桃长足象(Alcidosdes JuglandChao)、核桃举肢蛾(Atrijuglans hitauheiYang)是引起核桃早期落果的主要果实害虫。它们与核桃当年产量损失及损失率有密切关系,害虫危害越重,产量损失率越大,其中产量损失率最高可达75.3%。且对次年挂果量有影响,危害程度越大,对次年挂果影响也越大。因此,核桃果实害虫对次年该桃产量的损失不仅包括虫害落果部分还应包括因虫害而影响挂果减少量中的一部分。
Alcidosdes Jugland Chao and Atrijuglans hitauhei Yang are main fruit insect pests of Juglans regia Linn.,and will cause the early dropping of fruits.They are closely related to the yearly output and loss rate of walnuts,and the more serious the extent of injury is,the greater the output loss rate is.The highest output loss rate is 75.3%.And they will impact on the volume of bearing fruit in the following year,the more serious the extent of injury is,the greater the impact is on the volume of bearing fruit in the following year.Therefore,the following-year output losses of the fruit insect pests of Juglans regia includes not only the losses caused by the fruit insect pests,but also the losses caused by the impact on the volume of bearing fruit.
