| 摘 要： | 研究了红秋葵上斜纹夜蛾的发生规律及控制技术。结果表明，斜纹夜蛾是红秋葵上发生的主要害虫，其自然种群数量随季节变动，在7—8月达为害的高峰，温度升高明显有利于其种群数量的增长．种群数量变动与温度呈密切正相关，其回归关系式为：Y。=17．4924＋0．2031X．-0．0005942X；；浓度为1gDW／l（10mL的柑橘、艾蒿提取物喷施后．药后3d的校正防效分别为83．69％、82．22％，其次是曼陀罗、蓖麻和蛇床子提取物喷施后，药后3d的校正防效分别为78．81％、72．96％和71．04％。

| Abstract: | The occurrence regularity and control technique of Spodoptera litura on Abelmoschus esculentus were studied. The result showed that S. litura was the main pests of red okra. Population dynamic of S. litura was significantly affected by season and temperature. There was a peak from June to August. The influence of temperature on population dynamic of S. litura could be described by the equation： YI= 17. 492 4＋0. 203 1X1--0.0 005 942X;The orrection control effect was 83.69% and 82. 22% after 3 days spraying with 1 gDW/100 mL extracts of C. reticzdata and A. argyi. The orrection control effect was 78.8%-72.96% and 71.04% after 3 days spraying with 1 gDW/100 mL extracts of D. rnetel, R. comrnunis and C. monnieri. |
