桃树苹小卷叶蛾防治方法研究

Study on Control Methods of Peach Adoxophyes orana

[目的]研究防治桃树苹小卷叶蛾的有效方法。[方法]根据苹小卷叶蛾危害桃树的特点设置采用药剂防治、采用药剂防治且在幼虫盛发期前摘叶、采用药剂防治且进行果实套袋3种处理,调查果实被为害的百分率。[结果]仅采用药剂防治处理的被害果率达35.00%,极显著高于其他2种处理;采用药剂防治且在幼虫盛发期前摘叶与采用药剂防治且进行果实套袋处理间被害果率差异不显著,但套袋处理效果更佳,果实被害率为0。[结论]在苹小卷叶蛾为害期前进行果实套袋,可有效防治该虫发生。

[Objective]The study aimed to find out efficient control method against peach Adoxophyes orana. [ Method] Chemical control, chemical control and picking leaves before larvae peak period, chemical control and fruit bagging were designed as treatments according to the damage characteristics of Adoxophyes orana on peach, and the percentage of the damaged fruits was investigated. [ Result ] The pereentage of the damaged fruits treated by chemical control reached 35.00% , which was significantly higher than the other two treatments; the control effect of the chemical control and fruit bagging treatment was better than the chemical control and picking leaves before larvae peak period treatment, but no remarkable difference was observed. [ Conclusion ] Bagging fruit before the damage period can effectively control the oecorance of Adoxophyes orana.
