摘　　要：[目的]明确在库尔勒香梨生产中香梨优斑螟所用防治技术。[方法]走访调查库尔勒香梨的主要种植区域香梨优斑螟防治技术。[结果]果农重视香梨优斑螟越冬代的化防控制,但对其发生规律不清楚,多数仅仅当做食心虫(梨小食心虫、苹果蠹蛾和香梨优斑螟)进行防治,而它们的发生时间存在很大差异;糖醋液对于香梨优斑螟诱集效果很好,在调查中使用其进行测报或防治的极为少见;该虫既可为害果实也可为害香梨主干和枝干的韧皮部,由于韧皮部虫斑明显,易造成树势衰落和伴随着腐烂病发生,果农普遍对其重视,但防效甚微。[结论]香梨优斑螟的综合防控技术水平较低,有必要加强香梨优斑螟发生规律和成灾机制的深入研究,结合生产实践制定科学的系统防控体系。Objective To make clear the control methods of Euzophera pyriella Yang in Korla fragrant pear production. [Method] Investigating the control methods of Euzophera pyriella Yang in the main planting areas of Korla fragrant pear. [Result] Farmers paid attention to the chemical control of the overwintering generation of Euzophera pyriella Yang, but not mastered its occurrence regularity. Most just controlled as the moth. But there was a big difference in the occurrence time of Grapholitha molesta （Busck）, Cydia pomonella （L.） and Euzophera pyriella Yang. The trapping effect of sweet and sour liquid on Euzophera pyriella Yang was very good, but it was rarely used in forecasting and prevention of that pest. Fruits, brancheds phloem and trunk phloem of fragrant pear all could be damaged by Euzophera pyriella Yang. Farmers pay attention to that pest for the obvious insect spots in phloem, but received little control effect. [Conclusion] The further study on ccurrence regularity and disaster mechanism of Euzophera pyriella Yang was required for the low level of comprehensive prevention and control technology. The scientific prevention and control system need to be established according to the production practices.
