| 摘 要： | 栎线小卷蛾的幼虫危害梨树的花和嫩叶,且种群数量逐年增大,已成为影响临夏州皮胎果产业发展的重要害虫。通过对栎线小卷蛾幼虫为害皮胎果梨花的损失率进行研究,并根据近几年栎线小卷蛾幼虫防治技术推广应用实践,确定栎线小卷蛾幼虫防治指标,结果表明：皮胎果花蕾损失率与栎线小卷蛾幼虫虫口密度之间呈极显著的正相关线性关系,虫口密度越大,落蕾量越大;栎线小卷蛾幼虫防治指标为7头/100花。

| Abstract: | Flower and tender leaf of Pyrus ussuriensis were damaged by larvae of Zeiraphera isertana,and population amount increased year by year,Zeiraphera isertana have become important insects in Linxia and they had influence on production development of Pyrus ussuriensis.The study was carried out on the loss rate of Pyrus ussuriensis damaged by Zeiraphera isertana in this paper,based on popularization practice of control technique of Zeiraphera isertana,control index of Zeiraphera isertana was determined,the results showed that there was a highly significant positive linear correlation between loss rate of Pyrus ussuriensis bud and the population density of Zeiraphera isertana,and the population density of insects was larger,loss rate of Pyrus ussuriensis bud was larger;control index of larvae of Zeiraphera isertana achieved 7 per hundred flowers. |
