| 摘 要： | 扑虱灵对稻飞虱的防治效果，及对捕食性天敌的毒性，进行了田间试验，并与叶蝉散，杀虫双的使用结果作比较．试验结果表明，扑虱灵对稻飞虱的防治效果达93％，与叶蝉散，杀虫双相比较。防治效果提高了2．39～32．85％．对黑肩绿盲蝽和蜘蛛种群具有不同程度的选择性，维护较低的稻飞虱与天敌的比值，有利于天敌作用的发挥，维持对稻飞虱较长的残效期，基本上可以控制稻田后期飞虱的增长．

| Abstract: | The present paper dealt with the killing efficiency of the pesticide buprofezin on the plant hoppers and their predacious enemies.The result of the field test showed that the control efficiency of buprofezin on the plant hoppers counted up to 93% compared with the checked plots.The rice yield of the test plots with buprofezin had increased by 119 kg over the checked plots and by 30.8-45.1 kg over the plots with other pesticides.The pesticide could re- duce the pest population and kill less the predacious enemies. |
