| 摘 要： | 油菜是临夏州最重要的经济作物，受多种害虫危害，尤其是苗期（子叶～7叶）。本实验在2012年设在甘肃临夏州和政县，选用2种药剂（毒死蜱与辛硫磷）来防治春油菜苗期主要害虫油菜跳蚤甲（Psylliodes punctifrons Baly）。比较了2种农药及2种施药方法对害虫防效的差异，分析防效与产量之间的线性相关性，并从中选择出适宜保苗、保产的农药。对春油菜苗期害虫防治提出了建议，为临夏州春油菜区害虫综合防治提供了一定的理论支撑。

| Abstract: | Rape is the most important economic crop in Linxia, and often is attacked by many pests, especially in the seedling stage （cotyledon-7 leaves）. This research was done in double-low rape fields in Hezheng County, Linxia Prefecture, Gansu Province in 2012, expecting to use two kinds of medicines （chlorpyrifos and phoxim） for spring rape in the seedling stage to control one of its primary pests： Psylliodes punctifrons Baly. Different control effects of the 2 pesticides and the spray methods （seed dressing＋spraying, spraying） were counted by comparison, and correlation analyses of control effects and rape yields were made, and then the suitable pesticides and the methods were picked out. The paper put forward several advices for pest control of spring rape in the seedling stage, and provided the technical and theoretical support for the comprehensive pest control of spring rape in Linxia. |
